Nano Dispersions Technology was established in as an association of high level engineers from Venezuela, Japan and the USA, with a strong global network that includes other research laboratories, world class experts on fluid mechanics and rheology, mechanical design, mixing technology, formulation engineering, combustion, finance and administration. Our business model aims at establishing new ventures and promote business around innovative technologies or products, based on nanodispersions developed by our laboratory and our network.
On occasion, we engage in technology development for third parties. Along with many years of experience in the physicochemical formulation and mixing of dispersed systems, NDT holds a cavitationfree mixing technology capable of reaching nano-sized drops and particles in top-down process schemes.
Embedded in the processes we test in our laboratories and pilot plants is the ability to scale up the manufacturing of virtually any product we design. The robustness of the latter capability stems from fundamental fluid mechanics principles. One major technological development is ready to launch the production of a liquid fuel based on colloidal petroleum coke and coal particles.

From branded products to entirely unique solutions Prior has the tools to provide for your needs. Are we finally seeing some progress, towards the multibillion dollar markets emerging? Are there any companies making money from Printed Electronics?
Over the last couple of years I have noticed significantly less noise about printed electronics than in the past decade. Are we in a period of calm before a storm or are we seeing real progress from research to development? No one talks about this anymore. In a sense, there is an increasing maturity in the industry. Gone is the wild hubris, the extravagant claims to be reinventing the world. Weekly press releases claiming to be able to walk on water are replaced by a new reality. In the real world, just how do you move from research lab to production?
This move is proving harder than many had anticipated. The printed revolution is promised low manufacturing costs, green energy efficient devices, rollable, flexible screens and many more desirable features and qualities. Large global companies involved in printed electronics have large high profile research projects, They are addressing big challenges such as OLEDs Organic Light Emitting Diodes for general lighting applications in global markets.
These companies need to see big addressable markets to justify the big research budgets; nothing else will feed these machines to justify the investment for future growth. Will the break through ideas and devices come through these major international companies or will be it be through the small SMEs working quickly and cheaply with low overheads going after niche markets? In my travels within the printed electronics industry I see lots of great ideas.
Many of these could be genuinely game changing. I personally know of quite a few printed electronic products that will come to market in the next 12 months. The results of a meeting of minds. I have long advocated. However, organising this mix is harder to achieve than would be expected. The two worlds do not drink in the same bars. I know from personal experience that artists, designers and creatives are fascinated by the hard science magic that scientists weave and, in turn, scientists are surprised by the ideas generated by a community that tends to use the right side of their brains: Many companies simply do not get it…never having had the experience of working with creative people and not seeing the value in cross fertilization.
They are rare occasions and are increasingly few and far between. Also many science and research based companies struggle when faced with the difficulty of understanding the different vocabulary of the creative language. This is a shame as I know from personal experience that it is at such meetings that the magic happens and we need more of it.
Solutions to problems that do not exist or never needed solving. Is printed electronics is coming of age? We are now learning to manufacture in volume, I expect to see a flood of press releases over the next year announcing real innovations and developments in printed electronics, but to take it to the next level we need to bring in the creative community. Richard Kirk, Chief Executive Location: We can not leave product design and invention solely to science and research teams.
Often, we end up with fantastic science being shoe. Whilst hosted and run by the School of Engineering, the centre is fully multidisciplinary with users and collaborators in the schools of Physics, Chemistry, Medicine, Biochemistry and Cell Biology. The centre is run as a pseudo-industrial operation by 18 technicians and full commercial access to the centre is available through the startup company Kelvin NanoTechnology. Over the last 5 years over international companies and 90 universities have used the facility either for collaborative research, development or for delivery of unique solutions using the expertise at Glasgow.
Engineers from industry rub shoulders with PhD students and postdocs in the cleanroom. The centre holds the world record for the smallest features written by electron beam lithography of 2.

Such accuracy allows nanogaps between metal electrodes to be made for chemists interested in probing individual molecules. For making nanoscale devices, low damage pattern transfer is also an important capability. Recently the centre has used 5 nm lithography followed by reactive ion etching with low energy to fabricate Si nanowires of 1.
With this capability, research aimed at delivering 10 nm CMOS transistors, the fastest telecoms lasers and integrated Si photonics all have major industrial interest. In optics, work on plasmon filters using nanopatterned holes allows different colours to be filtered.
A nanogap created for undertaking spectroscopy of single molecules and a Si nanowire for sensing applications. Researchers at Glasgow were the first to demonstrate that mesenchymal stem cells could be directed to grow only into bone through the use of nanopatterned surfaces.
The technique is now being trialled in hip replacement surgery at the Southern General hospital in Glasgow. The Centre is always happy to discuss solutions with new collaborators and customers. There is increasing emphasis within healthcare on the use of preventative medicine rather than reactive strategies and treatments. Such strategies deliver enhanced healthcare in a more efficient and cost effective manner. Point-of-care screening diagnostics provide an essential basis for this to be delivered. A major opportunity to deliver preventative medicine is via the wider use of hand held sensing instruments.
These instruments allow ordinary medical staff, or even untrained personnel, to carry out rapid tests for infection at the initial consultation stage. Formerly such tests would have required costly laboratory analysis and incurred significant time delay. In addition, transportable point of care diagnostics permit screening to be carried out in locations remote from conventional pathology laboratory and healthcare facilities.
This enables the monitoring of treatment strategies in the field plus more rigorous implementation. A suite 30 success through nanomaterials.

Work has been under way for nearly a decade into developing nanostructured materials for a wide variety of applications and some of this has major potential for making a significant impact on our society and is beginning to be translated into industry.
A spin-out company, Polyfect Solution Limited PSL , was set up in July by Professor Mo Song to exploit the development of a novel, patented method for fabricating functional polymer powders. The technique solves the problem of dispersing nanoparticles into polymers for the production of both nanocomposites and nanocoatings without the use of chemical additives. A very wide range of applications exist across a number of quite different industries.
Other applications include the dispersion of conductive fillers such as carbon black, carbon nanotubes and graphene into polymers to provide anti-static packaging, flooring, fuel systems and housing for electronic devices, whilst taggant latex coatings offer opportunities in security protection [Note: A taggant is a chemical or physical marker, which can include the use of nanoparticles, that is added to plastics and other materials during manufacture and which help to identify products and their source]. Other work involving nanocomposites based on polymers includes the incorporation of a novel organoclay based on a plant oil surfactant into polylactic acid that offers the potential for biodegradable nanocomposites for packaging.
Being developed by Dr Noreen Thomas, additional work on the nanofiller system has shown significantly reduced water vapour permeability and improved biodegradability. Meanwhile, Prof Sanjay Rastogi is exploring the inclusion of fillers such as carbon nanotubes and nano zirconia into polyolefins to influence the crystallization behaviour of the polymer with the goal of achieving highly oriented polymeric structures that display enhanced tensile modulus, impact strength and viscosity.
Work is also ongoing in the field of nanostructured metals. Dr Simon Hogg is exploring the development of bulk nanostructured aluminium alloys for high strength applications. Nanoquasicrystalline aluminium alloys containing high levels of iron and chromium are promising materials for attaining elevated temperature capability and ultra high strength in light weight materials.
They also have the advantage of tolerating large impurity contents so can be made using cheaper and recycled material. However, despite their attractive properties the production of these materials has been restricted to the laboratory scale to date. Current work is now concentrating on a detailed characterisation of the alloys using synchrotron X-ray and neutron radiation and electron microscopy.
This is helping in the development of an understanding of the complex microstructure, thermal expansion behaviour and dominant strengthening mechanisms. The occurrence of Tin Sn whiskers on electroplated surfaces, typically from a micrometre to several millimetres long but just tens of nanometres in diameter has become of major concern to the electronics industry. Whisker growth mechanisms are still unclear and methods of mitigation are mostly concerned with, sometimes unreliable, polymeric conformal coatings. Replacing electroplated Sn-Pb finishes with Sn is accepted industrially, but can lead to enhanced tin whisker growth.
For in-service electronics a new generation of structurally modified polymeric conformal coatings will be produced, capable of acting as a barrier on surfaces with a high propensity to whisker growth. It is hoped that this dual approach will see a marked reduction in whisker growth from currently industrially utilised coating processes.
In the ceramic field, licensing is currently under way for research that has led to the ability to produce a range of genuinely nanostructured ceramics made from powders as fine as 20nm; this is smaller than the size of a typical virus. These ceramics have been found to display some extremely useful properties. The new nanostructured material has been shown to survive at least 3 weeks with no trace whatsoever of the phase change even beginning to occur. This has the potential to lead to the use of zirconia in such critical applications as hip replacement implants, dental ceramics and even valves for the petrochemical industry.
The lower firing temperature involved with nanostructured ceramics means that much cheaper metal electrodes can be used, very significantly reducing the price of components. Collaborative innovation in materials chemistry is a key driver to develop and commercialise materials with nanoscale functionality — and which play a crucial role across high value, advanced manufacturing.
By delivering knowledge transfer, KCMC helps companies to shorten innovation-to-market timescales for sustainable solutions - notably across the energy, healthcare and new materials sectors. The application of nanotechnology for a diverse range of sensors has attracted steadily-growing attention. Research at KCMC partner the University of Manchester is focusing on the discovery and development of novel materials for use in platform technologies for sensor applications.
Energy-saving glass is key in reducing both heat loss from buildings and fuel consumption. In the world of engineering and structural components, nanocomposite coating technology has delivered significant benefits over classic electroplated chromium. In an ongoing development with MSC Ltd. They reduce cost and eliminate use of toxic Cr-plating solution.
Involved in the project from the beginning, KCMC helped to make the plan of development, schedule of delivery and implementation of tasks. These notably include thin film transistors utilizing organic semiconductors, and photonic devices.

SAFC Hitech and Pilkington have collaborated in adaptation of atomic layer deposition ALD to put energy saving layers onto window glass for homes application. The UK is home to a number of world-class companies whose success depends on their development and use of advanced materials. Examples of advances in materials technology include the use of advanced composites in aircraft and racing cars to reduce weight, reduce emissions and lower fuel bills.
The UK has developed new ways of designing lighter power modules through smart choices of materials. The increasing use of smart materials for healthcare, sports applications and the fashion industry has catapulted the UK to become one of the top nations in the world for design and innovation. A major challenge for the UK is to ensure that there is an ongoing investment in materials science and technology to support the much needed innovation and wealth creation by UK businesses.
Making choices between different technologies is both challenging and complex. Materials advances are at the heart of solutions enabling, for example, the effective end-of-life deconstruction of structures and the recycling and reuse of product waste. Everyone is familiar with the environmental pressure to reduce waste by recycling, but another factor is the preservation of materials that may become scarce or expensive. Supply shortage is a good reason for recovering materials. Materials security means making sure you have the materials needed to build the item that has been designed.
It means maximising recycling and recovery, improving antitheft measures, substituting for more-available materials where possible, but more importantly ensuring supply. In an economy fuelled by materials, we need to be sure that we can get these and keep them for a very long time.
A big factor is avoiding the waste of raw materials and the energy required for production and disassembly. Large-scale energy crises have often troubled modern society, but a huge amount of low-intensity energy is available throughout the environment if it can only be harvested and used.
BUY ON AMAZON'S NEVER EASY
Many small-and-numerous sources go largely ignored. For example, advanced crystals in a road generate power when they are compressed by vehicles passing over them. Advanced materials are often key, and promise the availability of devices which may have maintenance-free lives of hundreds of years, deriving power from the environment in which they operate. This source of energy includes photovoltaics power from light , thermoelectrics power from heat , piezoelectrics power from pressure and electrodynamics power from movement. In many cases energy harvesting and storage depends on materials capability and cost.
We have to make sure that the cost of the materials is low enough to do these things. That is where materials science comes in. The aim of development is to reduce costs, make installation easy and the result robust. There are new materials available to meet the growing need for biomaterials and biomarkers to manage and monitor serious clinical conditions. Technical textiles with antimicrobials have been developed to control the spread of MRSA in hospitals.
In areas where cleaning alone cannot solve the problem, such as in awkward corners and joints, advanced combinations of new and traditional materials can, for example, rotational or injection moulding of polymers enables many hospital items, such as bedside cabinets, to have rounded inner corners and few joints to allow easy and effective cleaning. Nanocrystalline silver is used in which the material is manipulated at the nano scale so that its surface area, and therefore effectiveness, is much increased. Copper is reported to kill This has become a reality with the advances in sensor design, integration of smart materials and ultra-low power microprocessor and wireless technologies.
Such materials are ideal for impact protection clothing for sport and other uses, such as the ballet pointe shoe. The life of the professional ballerina has traditionally been a tradeoff between grace on stage and excruciating foot pain. With the help of the Materials KTN, a new hightechnology shoe has been developed based on a shockabsorbing polymer that hardens on impact to cushion the foot. The creative use of advanced materials by product designers is an important contribution to many of the innovations described above.
Through its initiatives, designed to help accelerate the rate of industrial innovation, the KTN is also helping to equip young people with many vital skills and attitudes for innovation, including problem-solving, curiosity, interrogation skills and multidisciplinary teamwork. This is because as the rubber warms up, it begins to leak air.

Nanotechnology in paints, coatings and printing inks Substances with nanoscale particles are nothing new to the paint and printing ink industry; 2, years ago the Roman architect Marcus Vitruvius Pollio used synthetically manufactured soot for wall paints. As we know today, that soot came in the form of nanoparticles. Silica is another example of a material that has been used, in particle sizes of between 4 and 20 nanometres, for almost years to improve the flow properties of paints.
Modern microscopy technology scanning electron microscope and atomic force microscope now enables these nanoscale particles and structures to be seen visually and measured, allowing scientific research into the inner makeup of paint, coating and ink films. It is now possible to use nanomaterials in a targeted manner for their formulation which have become of major significance in the development of new coatings.
Nanotechnology, relying on physical, chemical or biological effects of particles or material structures in a size range of less than nanometers, is a key technology for the future. Over the next 30 years, the number of improvements to conventional paint products and new functional paints is expected to increase at breath-taking speed.
It should not be forgotten, however, that particles in this size range have existed long before industrialization. Nature produces immense amounts of nanoparticles through the weathering of stones and rocks, in forest fires or on sea shores. By contrast, the technical production of nanoparticles and nanostructures for the purpose of achieving novel properties has started only recently. Important novel properties have been achieved by the addition of nanomaterials to products such as: Easy-to-clean paints Barrier inks and coatings Effects paints Antibacterial paints Scratch-resistant paints Photocatalytic paints Paints with UV protection Electromagnetic radiation screening paints.
Furthermore, the practical application of nanotechnology is producing research in the following fields: Electro-conductive paints Self-healing paints Nano-primers for anti-corrosive paints Heat-insulating paints. Nanomaterials currently used in paints, coatings and inks include some of the following substances: Titanium dioxide has photocatalytic properties in nanoscale form and is found in certain wall paints for removing organic pollutants from ambient air. Nanostructured silicon dioxide serves as a rheological additive and is also used in self-cleaning wall paints.
UV protection in transparent coatings is the most important application for iron oxide and nanoscale zinc oxide. Nano-size carbon black protects against electromagnetic radiation. Silver in nanoform is a constituent of wall paints for hospitals and food processing operations, in order to prevent attack by bacteria and other micro-organisms. These have shown that, when sanded or subject to wear, or at end-of-life after ageing, any added nanomaterials are not released from the film matrix into the environment. Nanocoatings — a Guide to the Perplexed The scale-up from lab to production of nanocoatings hits the double problem that coating is hard and nanoparticles can be difficult to deal with.
This means that there is only one relevant technique that can be used — slot coating. Here we meet a key problem. Fortunately, Hansen Solubility Parameters HSP are a proven, robust method for defining likeness, via three parameters for each solvent, polymer or nanoparticle, that capture the Dispersion, Polar and Hydrogen Bonding characteristics. By measuring the HSP of the nanoparticles and the polymer it is then simple to calculate which solvents are going to be compatible with each component. Importantly, if there is no single solvent that has the right properties cost, safety, volatility… HSP allow you to optimise a solvent blend to give you the right HSP using solvents which, on their own, may be of no use.
This would be impossible with conventional slot coating using a steel roller. If the contact angle of the coating to the substrate is low then a thinner coating will be stable. So, for thin coatings you have to be either much cleaner so there are no initial defects or have a much lower contact angle between coating and substrate. This effect is familiar to painters: So coating defects that previously flowed out before reaching the oven can suddenly be full of coating lines if the thickness is reduced even by a relatively small percent.
Fig 2 For a nanoparticle with HSP of [ As the volatile 1,3 Dioxolane evaporates first, the HSP Distance Ra increases rapidly which might be desired to produce rapid phase separation of the particles. Further tuning of the solvent blend lets you control what happens during evaporation — for example the volatile component might be especially good for the quantum dots so they will crash out early during evaporation if that is required for overall functionality.
Such a trick is now being used for controlled phase separation in organic photovoltaics. Summary Experience shows that these three principles are relatively little-known in the nanocoatings community. But I, and others who now use these ideas routinely, can confirm that by taking these principles on board the nanocoatings team will be able to produce better coatings in a shorter development time. Interested readers can explore the coating and defect issues via TopCoat www. Nanotechnology revolutionizes coatings industry Nano-sized particles are not new to coatings, but the sector is uniquely placed to benefit from the explosion of ideas and potential for new functionalities that nanotechnology can bring.
After three successful programmes in Nottingham, the popular one-day event looks set to become an annual fixture. Rather than simply increasing hardness as might traditionally have been done in solventborne clear coats for cars, BYK has modified the particle surface to enhance polarity differences between nanoparticle and resins, thus increasing elasticity.
The coating then acts like a foam and bounces back after an impact, avoiding damage. To reduce damage caused by UV light, organic UV absorbers are often incorporated into a coating. However, these absorbers commonly suffer from migration and degradation over time. On the other hand, inorganic UV absorbers, such as zinc oxide and cerium dioxide, do not migrate, so the potential is there for them to keep their properties for the life of the coating.
BYK is conducting trials using nanoparticles of organic absorbers such as these, noting that particle size will affect the transparency of a coating. BYK is also working with carbon nanotubes CNT , which can bring electrical and thermal conductivity to coatings and inks, even at very tiny amounts, but have a strong tendency to form agglomerates. Second to present was Intrinsiq Materials, which has developed a copper nanoparticle-based ink for printed electronics applications. Conductivities are comparable to commercial silver inks, but much, much cheaper. Potential applications include security, displays and photovoltaics.
The company has additional inks under development, including nanoparticle-based nickel and silicon. It is also part of a government funded programme investigating the cost effectiveness and viability of printed copper antibody-based biosensors for disease detection, initially targeting sexually transmitted diseases such as chlamydia and gonorrhoea. Compared to devises that reply on gold and glass, these have the potential to dramatically reduced cost and time. Evonik is producing silica-nanocomposites that are ready to use and give a very high scratch and abrasion resistance to coatings.
Particle sizes are kept small enough so there is no loss of transparency or gloss. The composites are also able to enhance barrier properties. Unlike waxes, silicone oils or other surface modifying agents that work only in the top layer of a film, these are dispersed throughout the resin matrix. The conference also heard from TransCond, a European funded project that is looking to replace high VOC volatile organic compounds and heavy metal formulations in electrically conductive coatings.
At the moment, the focus is on how to take carbon nanoparticles and introduce them into a VOC-free paint polymer system. Corrosion control and anti-fouling, two important functions served by coatings, were discussed separately. According to TWI Technology Engineering, the next generation of anti-fouling coatings are likely to have low fluorine content — even though fluoro-polymers dominate the market today - and will be based on nano-structured surfaces.
Johnson Matthey, the international speciality chemicals company, has dedicated capability to produce a range of nanopowders using the flame spray pyrolysis technique. The Flame Spray Pyrolysis Facility can be used to produce a wide array of nanopowders ranging from single metal oxides such as Al2O3 to more complex mixed oxides or catalysts. The spray is combusted and the precursor s converted into nano sized metal or metal oxides particles, depending on the metal and the operating conditions.
The technique is flexible and allows the use of a wide range of precursors, solvents and process conditions, thus providing control over particle size and composition. Flame spray pyrolysis is a versatile technique for producing nanoparticles and can be used to make metal, metal oxide and more complex nanoparticle materials. Johnson Matthey has specialised in using the technique to make nanoparticle catalysts and has developed considerable inhouse expertise in this area. This knowledge is transferable into other application areas. Figure 2 shows the spectra of both ZnO nanomaterials. It is important to note that no stabiliser was used.
This is in agreement with the small particle size revealed by TEM analysis and the characteristic ease at dispersing the flame spray material in liquid media.

It was formed to enable the University to address global issues involving open innovation, in partnership with companies of global importance in the supply chain of the photonics and electronics industries. The CAPE partners are strategically placed in relationships where their interests do not overlap or conflict. The mix of partner interests has shifted over the time but the existing partners continue to represent global business interest. Now, after eight years, we know it has worked well. It is a joint agreement between the university and industrial partners , taking a balanced view of academic and industrial interests.
All the industrial partners are represented on the CAPE Steering Committee, and the University and the industrial partners have equal representation. Through joint governance and joint sponsored research, the CAPE Partnership has developed a research portfolio at the cutting edge of contemporary technology with very significant societal relevance in its focus on topical areas, from nano technology to the built environment.
CAPE and its CPA are constantly evolving to adapt to internal and external environmental needs with the aim of enhancing academic research and creating added value for business. In the electronic and photonic field, developing research to the product stage takes a long time, often a 15 to 20 year period. One has to be persistent, forgeing long-term relationships and investment. The original inventions and focused early stage research work in CAPE have 56 success through nanomaterials.
The CIKC works with UK industry enterprises to create business propositions and a knowledge base for commercialisation in the field of molecular and macromolecular materials - another important application of nanotechnology. The benefits of CAPE have been two-fold. The University researchers have gained too.
University research staff are often academically excellent, but are sometimes not too aware of what is going on in the commercial world. CAPE has helped a lot in that respect. With our partners, CAPE plans to build on its success and integrate with a wider area of the academic community, with a broader range of business enterprises and organisations, including small and medium companies, thereby reflecting current trends in the industrial landscape in the UK. A world centre of excellence to deliver business viable technology from scientific concept to demonstrator through academic-industrial collaborations at the University of Cambridge; A communication platform for CAPE partners to access technical knowledge and business information distributed over the value chain of the global electronics and photonics industry through not only internal interaction between the partners but also external engagement to key knowledge holders in fields outside the CAPE community; A focus point to create opportunities for all partners through brand building, technology demonstration, outreach and networking with the global community.
Providing machine vision lens solutions Best Scientific is proud to introduce the arrival of the new Optem Fusion Micro-Imaging Lens system, featuring the following: Dr Eric Best eric bestscientific. It offers quantitatively surface texture and surface form in three dimensions and at high speed. The technique is suitable for a range of samples from super smooth to rough, allowing direct comparison of a wider range of surfaces than any other method.
Scanning the fringes through the surface and then processing the information gives a quantitative 3D image with 0. The data can then be used to generate accurate quantitative parameters such as roughness, step height, feature width, form, volume, and angle. Recent developments also mean that thickness top surface roughness and interface roughness of semi-transparent films can now be measured. Central Oxford was no place for such sensitive equipment and the University opportunistically purchased the former Cookson Group technology centre at Begbroke, five miles north of Oxford.
That initial mix of young businesses working in proximity to researchers, sharing facilities and knowledge remains a key feature of the park which today is home to around people around half of whom are working for companies. Begbroke is attractive to early stage and rapidly growing companies who benefit from the incubator environment fostered on the site.
There is no denying that Begbroke has achieved its key aim to encourage innovation and enterprise guided ably by Professor Peter Dobson, its academic director. Oxford Gene Technology OGT , which is now acknowledged to be one of the most successful gene sequencing licensing companies in the world, established itself at Begbroke in and continues to base its operations at the site. Another more recent example of success is Oxford Nanopore Technologies ONT , which was spun out from the University using technology developed by Professor Hagan Bayley in the Department of Chemistry, started at the Begbroke Science Park in and grew to employ around 70 scientists before moving to larger premises at the Oxford Science Park in The company is developing a unique nanopore platform for the detection of biomolecules and sequencing of DNA and is currently valued at over GBP million.
The proximity of researchers from different departments encourages collaboration. Dr Helen Townley of the Department of Engineering Science is working with medics and colleagues from the Institute of Biomedical Engineering and the Department of Materials using novel nanomaterials to improve imaging of lymph nodes to investigate gynaecological cancers.

The emergence of the graphene family of materials is giving rise to exciting applications using properties such as the exceptional in-plane electrical conductivity, outstanding thermal conductivity, high strength as well as outstanding resistance to gas permeation.
Graphene research is rapidly developing, as researchers and industry strive to validate and develop commercial products that exploit these properties in the fields of electronics, battery electrodes, super-capacitors, structural composites, conducting polymers, packaging films, printable inks and biomedical technologies amongst others. However, for any new technology to reach its maximum potential, any health risks posed by exposures to hazards need to be identified and mitigated.
What are the risks from graphene and should you be concerned? The concern about graphene relates to its plate-like shape and the potential problems this may cause in sensitive regions of the lungs where oxygen and carbon dioxide are exchanged. It is crucial that this region remains clear and healthy. For most substances, this is not normally a problem as the lung has evolved so that larger particles cannot reach this region of the lung.
