Scientists have created an innovative tool to directly detect the delicate, single-molecule interactions between DNA and enzymatic proteins. Their approach provides a new platform to view and record these nanoscale interactions in real time.
Using nanometer-scale components, researchers have demonstrated the first optical rectenna, a device that combines the functions of an antenna and a rectifier diode to convert light directly into DC current.
Material researchers are developing a procedure that allows them to mimic the complex fine structure of biological composite materials, such as teeth or seashells. They can thus create synthetic materials that are as hard and tough as their natural counterparts.
To the growing list of two-dimensional semiconductors, such as graphene, boron nitride, and molybdenum disulfide, whose unique electronic properties make them potential successors to silicon in future devices, you can now add hybrid organic-inorganic perovskites. However, unlike the other contenders, which are covalent semiconductors, these 2D hybrid perovskites are ionic materials, which gives them special properties of their own.
To provide a means for both comparing and selecting these energy-harvesting nanogenerators for specific applications, the Georgia Institute of Technology research group that pioneered the triboelectric nanogenerator (TENG) technology has now proposed a set of standards for quantifying device performance. The proposal evaluates both the structural and materials performance of the four major types of TENG devices.
Scientists have invented a new way to use chirality to make a wrench. A nanoscale wrench. The discovery allows to precisely control nanoscale shapes and holds promise as a highly accurate and fast method of creating customized molecules.
