In this project funded by the Danish EPA the Technical University of Denmark and National Research Centre for the Working Environment has initiated the development of a screening tool called NanoRiskCat (NRC) for the evaluation of exposure and hazard of nanomaterials contained in products for professional and private use.
The new cell shows potential to meet the major requirements for future device-level nonvolatile memory. RRAM is an emerging technology for nonvolatile memory, a candidate to replace NAND Flash technology in the scaling race to sub-10nm memories.
Researchers at Yale University have developed a novel nanoparticle with promising applications in gene therapy, a type of medical treatment that addresses the root causes of diseases now typically treated for symptoms.
An international collaboration led by the NIST Center for Nanoscale Science and Technology has used scanning electron microscopy with polarization analysis (SEMPA) to acquire images of the magnetic structure inside patterned nickel-palladium (NiPd) thin film nanostructures, revealing peculiar magnetization textures that can affect the behavior of these ferromagnetic alloys in experimental applications.
Researchers at Brown and Johns Hopkins universities have found optimal configurations for creating 3-D geometric shapes - like tiny, highly simplified geodesic domes that assemble by themselves. The Brown team developed the algorithmic tools, and the Johns Hopkins team tested selected configurations. The research may lead to advances from drug-delivery containers to 3-D sensors and electronic circuits.
Researchers spent 75 days on the job carrying out some very important homework - measurements in a "typical dwelling" of the release, distribution and fate of particles almost as tiny as the diameter of a single DNA molecule. Particles ranging in size from 100 nanometers down to 2.5 nanometers that were emitted by gas and electric stoves, hair dryers, power tools and candles were tracked and analyzed.
The Vienna University of Technology is the only research facility in the world, where single atoms can be controllably coupled to the light in ultra-thin fibre glass. Specially prepared light waves interact with very small numbers of atoms, which makes it possible to build detectors that are extremely sensitive to tiny trace amounts of a substance.
Researchers from Purdue and Harvard universities have created a new type of transistor made from a material that could replace silicon and have a 3-D structure instead of conventional flat computer chips.
A recent review provides an overview of interactions of nonbiodegradable, persistent nanoparticles with the immune system. Particular emphases include key factors that shape such interactions, cell-specific responses, allergy and immune-sensitive respiratory disorders.
