Simply making nanoparticles spin coaxes them to arrange themselves into what University of Michigan researchers call 'living rotating crystals' that could serve as a nanopump. They may also, incidentally, shed light on the origin of life itself.
A recent study conducted by the Swiss National Science Foundation revealed that the bulk of silver nanoparticles is retained in wastewater treatment plants, only little is known about the persistence and the impact of the residual nano-silver in the environment.
'Mottronics' is a term seemingly destined to become familiar to aficionados of electronic gadgets. Named for the Nobel laureate Nevill Francis Mott, Mottronics involve materials - mostly metal oxides - that can be induced to transition between electrically conductive and insulating phases.
The investigation of cluster explosion dynamics under intense extreme-ultraviolet (XUV) pulses has so far been limited to large scale facilities like free-electron lasers. In a recent publication it was shown that the research on clusters is now also possible with intense XUV pulses obtained in a laboratory-scale environment with a newly developed light source that makes use of the high-order harmonic generation process.
The just-launched PLACYD Project, coordinated by Arkema, is working on a unique block copolymer materials line to address all necessary building blocks, such as metrology, inspection and design tools, to accelerate the adoption of directed self-assembly technology by the semiconductor industry.
Researchers at the University of Pennsylvania have devised a method to study stress at the macro and micro scales at the same time, using a model system in which microscopic particles stand in for molecules.
Researchers have persuaded fibroblasts, cells that makes the extracellular matrix, to make a a well-organized scaffold. Its fibers are a mere 80 nanometers across, similar to fibers in a natural matrix.
Researchers from the National Institute of Standards and Technology (NIST) and the Food and Drug Administration (FDA) have demonstrated that they can make sensitive chemical analyses of minute samples of nanoparticles by, essentially, roasting them on top of a quartz crystal.
