A new type of polymer can show that it has changed shape. After exposure to UV light, the chain-like molecules emit a different colour of light. This opens a new pathway for research into how viruses function in a cell and how minor damage in rubbers and plastics can accumulate and lead to rupture.
Nanomembrane sheets made from nylon resemble a tangled web. The tiny iron oxide particles on the fiber surfaces can help clean toxic chemicals from water, but if the particles get separated from the web, they can become hazards themselves.
Researchers have solved a key obstacle in creating the underlying technology for miniature optical sensors to detect chemicals and biological compounds, high-precision spectroscopy, ultra-stable microwave sources, and optical communications systems that transmit greater volumes of information with better quality.
Engineers have discovered a way to grow graphene nanoribbons with desirable semiconducting properties directly on a conventional germanium semiconductor wafer. This breakthrough could allow manufacturers to easily use graphene nanoribbons in hybrid integrated circuits, which promise to significantly boost the performance of next-generation electronic devices.
Graphene has number of interesting properties that have led researchers to suggest either modifying components of Li-ion batteries, or using graphene as the energy-storage medium instead as promising solutions.
Scientists have created a solid-state memory technology that allows for high-density storage with a minimum incidence of computer errors. The memories are based on tantalum oxide, a common insulator in electronics.
