Insurance companies are major stakeholders capable of contributing to the safer and more sustainable development of nanotechnologies and nanomaterials. This is owed to the fact that the insurance industry is one of the bearers of potential losses that can arise from the production and use of nanomaterials and nanotechnology applications. Researchers have examined how the insurance market perception of nanotechnology can influence the sustainability of technological advances and insurers? concern for nanotechnology risks. They claim that, despite its role in sustaining technology development in modern society, insurers' perception on nanomaterials has been largely overlooked by researchers and regulators alike.
The surface force balance (SFB) provides measurements of surface and colloidal forces in liquids such as electrostatic surface forces, van der Waals forces, and solvation forces. Until now, the SFB required mica sheets as the substrate for measurements. This was the only material available in an atomically smooth state over centimeter-scale areas as well as being optically transparent as required for the optical interferometry. By replacing the mica sheets with graphene, electrically conducting and atomically smooth surfaces for the measurement of surface forces have now been created.
Advanced health monitoring systems and healthcare devices will become an integral part of the Internet of Things. As a harbinger of things to come, nanotechnology researchers have now demonstrated a smart thermal patch which can be used for thermotherapy for pain management in a user interactive way. To fabricate the device, the researchers used CMOS technology to devise a silicon based smart thermal patch which is flexible and stretchable.
Drawing attention to the possible implications of extreme weather does not answer the question what we can really do about the risks of climate change, and who will drive fresh solutions. Science - including nanotechnology - is an important part of the answer, and we need human ingenuity to step forward. To accelerate the process and help to push the boundaries of usable energy solutions, the Exergeia Project backs potentially groundbreaking inventions and innovations in all fields of alternative energy.
Graphene's properties appear to have almost limitless application potential, ranging from composite materials for the aerospace industry, next-generation batteries and supercapacitors, flexible displays and optical electronics and biosensors for applications in healthcare and medical devices. So why hasn't graphene, with the potential to vastly outperform the majority of currently available materials, been integrated into everything from wristwatches to ocean liners?
A majority of the members of the Environmental, Public Health and Food Safety (EHS) committee of the European Parliament approved several amendments to the draft regulation on novel foods, including one imposing a moratorium on novel foods containing nanomaterials. The EHS committee's amendments to the Commission's proposal show that the European Parliament and the European Commission clearly have two different approaches towards the regulation of nanotechnologies.
The use of copper as an alternative electrode material to silver would reduce the cost of conductive inks. Nevertheless, copper nanowire conductors face a serious bottleneck for future practical use in flexible and stretchable optoelectronics: although they are nearly as conductive as silver, this conductivity is not stable. Researchers have now demonstrated conductive copper nanowire elastomer composites with ultrahigh performance stability against oxidation, bending, stretching, and twisting. This material offers a promising alternative as electrodes for flexible and stretchable optoelectronics.
The successful implementation of graphene-based devices invariably requires the precise patterning of graphene sheets at both the micrometer and nanometer scale. Finding the ideal technique to achieve the desired graphene patterning remains a major challenge. Researchers have now demonstrated 3D printed nanostructures composed entirely of graphene using a new 3D printing technique. The method exploits a size-controllable liquid meniscus to fabricate 3D reduced graphene oxide nanowires.
