Potential for nano research recognised HCM CITY — Viet Nam has the potential to be one of the world’s leaders in nanomaterial research and development, according to an American scientist, professor Omar M. Yaghi of University of California at Los Angeles (UCLA). Yaghi is UCLA’s Jean Stone professor of chemistry and has received many awards […]
The European Commission is preparing plans that would see European firms build infrastructure in metal-rich African nations in exchange for access to key raw materials there, marking the EU’s latest effort to counter China’s dominance on the continent. Background In November 2008, the European Commission launched a Raw Materials Initiative aimed at facilitating companies’ access to […]
In an interconnected world, global issues demand integrative solutions. It’s a statement that many people would agree with – in systems where associations between cause and effect are complex, you ignore synergistic inter-relationships between factors at your peril.
Researchers at the University of California Berkeley have developed a new way to directly integrate ultrathin layers of compound semiconductors onto silicon substrates. The technique produces low-power, high-performance nanoscale transistors that can be switched on and off more quickly than their bulk counterparts.
Researchers at the University of Ulm in Germany have developed a new and powerful technique to accelerate drug uptake into cancer cells. The method beats slow diffusion-controlled processes – one of the most important limitations in chemotherapy.
The first biosensor made from plasmonic nanohole arrays has been unveiled by researchers at Boston University Photonics Centre in the US. The device, which exploits “extraordinary optical transmission”, can detect live viruses in a biological solution.
Researchers at Harvard University in the US have developed a new, clean and simple technique, dubbed “ice lithography”, to fabricate nanodevices. The method, which relies on using a thin film of water ice as a resist for electron-beam lithography, does not contaminate or degrade samples, unlike many conventional nanofabrication processes.
Researchers at the University of Glasgow in the UK are the first to have created “super-twisted light” in the lab. The light is so-called because it has a high degree of circular polarization and could be used to detect minute quantities of biological molecules in solution. Indeed, super-twisted light could help scientists study the proteins […]
The polarization of light can be rotated by almost 6° as it passes through a single sheet of graphene in a magnetic field, according to an international team of physicists. This latest property of graphene – a sheet of carbon just one atom thick – was unexpected because large rotations normally occur only in much […]
Researchers at the Nano-Science Center of the University of Copenhagen, Denmark, have developed a way to produce ultra-clean nanowires, overcoming one of the challenges to the production of such materials – controlling the production so the electronic structure is perfectly uniform throughout the nanowire.
Nanotechnology promises to play a major role in the automotive sector, and this article highlights applications already in use and ones we can expect in the future. The automotive sector is a huge consumer of material technologies and nanomaterials are expected to improve the performance of existing technologies significantly.
This article addresses regulatory issues of nanotechnology and takes an in-depth look at how the United States Environmental Protection Agency (EPA), the U.S. Food and Drug Administration (FDA), and the U.S. Occupational Safety and Health Administration (OSHA) have dealt with nanotechnology regulation since a November 2007 memorandum from the Office of Science and Technology Policy, […]
The United States National Nanotechnology Initiative (NNI) is currently accepting public comments on its draft NNI Strategic Plan. The NNI is a nearly US$1.8 billion multi-agency federal research and development initiative focused on nanotechnology innovation. The Plan is the framework that underpins the nanotechnology work of 25 NNI member agencies, with the aim of ensuring […]
Russian President Dmitry Medvedev, speaking at the annual RUSNANOTech Forum, said Russia must cut excessive tax burden and red tape if it is to become a major player in nanotechnology. Technological modernization, and nanotechnology in particular, has been one of the themes of Medvedev’s presidency. He said Russia must create internal demand for nanotechnology if […]
A recent article, “Debunking Some Misconceptions about Nanotoxicology”, in the journal Nano Letters, written by David B. Warheit from the DuPont Haskell Global Centers for Health and Environmental Sciences, addresses what the author perceives to be myths and misconceptions regarding nanotoxicology. Nanotoxicology studies are growing, and a general understanding of nanotoxicity is expanding, yet the […]
A team of chemists and engineers at the University of California, Los Angeles, United States, has developed a method for coating large surfaces with nanofiber thin films that are both transparent and electrically conductive. The thin film is a result of a vigorous agitation of water, dense oil, and polymer nanofibers that spreads over virtually […]
Researchers at the University of Buffalo, United States, have developed a novel technology to deliver a chemotherapeutic drug to specific cells in the lung without causing acute inflammation. The discovery is expected to have major implications for research and treatment of tuberculosis, as well as other inflammatory lung diseases. The technique uses quantum dots linked […]
Adoption of six nanotech innovations for energy efficiency has the same impact on fossil fuel consumption as shutting down every U.S. coal plant, says Lux Research. BOSTON–(BUSINESS WIRE)–The increasing consumption and diminishing reserves of fossil fuels will create significant issues for civilization, but energy efficiency can help mitigate the challenge – and advances in nanotechnology […]
Extracting drinking water from the sea to prepare for a world parched by climate change, and re-imagining aeroplane and ship hull designs for the best fuel efficiency, are two of the visionary applications of a new £2.4 million research project announced today (Friday 15 October) at the University. Professor Jason Reese of the University’s Faculty […]
(Nanowerk News) The National Industrial Chemicals Notification and Assessment Scheme (NICNAS) is introducing new administrative processes for the notification and assessment of industrial nanomaterials that are considered to be New Chemicals under Part 3 (Notification and Assessment of Industrial Chemicals) of the Industrial Chemicals Notification and Assessment Act 1989 (the Act). These new administrative arrangements […]
Dos países de América Latina destacan entre un grupo de cinco naciones en desarrollo donde se están haciendo avances en nanotecnología. Mientras en Brasil hay una incipiente pero creciente relación industria-academia, en México aún falta establecer una red nacional articulada. Así lo indica un informe sobre capacidad de innovación y sistemas de innovación en energías […]
