If you want to form very flexible chains of nanoparticles in liquid in order to build tiny robots with flexible joints or make magnetically self-healing gels, you need to revert to childhood and think about sandcastles.
Studies of the impact a droplet makes on solid surfaces hark back more than a century. And until now, it was generally believed that a droplet's impact on a solid surface could always be separated into two phases: spreading and retracting. But it's much more complex than that, as a team of researchers now reports.
The U.S. Food and Drug Administration has issued a final guidance for industry, 'Use of Nanomaterials in Food for Animals', which is intended to assist industry and other stakeholders in identifying potential issues related to safety or regulatory status of food for animals containing nanomaterials or otherwise involving the application of nanotechnology.
A miniaturized sensor based on Raman spectroscopy that can quickly and accurately detect or diagnose substances at a molecular level. The system can do chemistry, biology, biochemistry, molecular biology, clinical diagnosis, and chemical analysis,
Scientists discuss a new way to apply a widely used local-structure analysis tool - known as atomic pair distribution function (PDF) analysis - to x-ray scattering data from thin films, quickly yielding high-quality information on the films' atomic structure. The work creates new avenues for studies of nanocrystalline thin films.
