By combining expertise in nanophotonics and materials science, researchers have laid the groundwork for a chemical sensor on a chip that could be used in small portable devices to analyze samples in a lab, monitor air and water quality in the field and perhaps even detect explosives.
Researchers managed to reverse the electronic characteristics of a polymer known to disperse semiconducting nanotubes - while leaving the rest of the polymer's structure intact. By so doing, they have reversed the process, leaving the semiconducting nanotubes behind while making it possible to disperse the metallic nanotubes.
Advances in our understanding of the profound connections between atomic-scale processes and biological molecules serve to deepen, if not transform, the way we regard ecological processes - and, by implication, living things, no matter how invisible.
Using a unique single-molecule force measurement tool, a research team has developed a clearer understanding of how platelets sense the mechanical forces they encounter during bleeding to initiate the cascading process that leads to blood clotting.
Researchers have discovered a new type of Weyl semimetal, a material that opens the way for further study of Weyl fermions, a type of massless elementary particle hypothesized by high-energy particle theory and potentially useful for creating high-speed electronic circuits and quantum computers.
Scientists found that the interactions between particles trapped in light distributed along an optical microfiber, as well as the speed of particle movement were different based on the light's characteristics.
