By adapting a mode of the light field to a system under study, the interaction of light with matter can be optimized. In this context, the spatial distribution of the electric field of such a tailored mode plays an important role. Researchers use this approach to couple light to a single atom or individual nanoparticles.
LEDs made from nanowires will use less energy and provide better light. Researchers studied nanowires using X-ray microscopy and with this method they can pinpoint exactly how the nanowire should be designed to give the best properties.
Owing to recent spectacular advances in nanochemistry and nanomaterials sciences, substantial progress in the design and synthesis of synthetic nanoscale hybrid materials has been achieved with new or improved properties. This allows scientists to fabricate new hybrid materials that can be used in individual and multimodal imaging techniques simultaneously.
Biomedical engineers have invented a new device that more quickly and accurately 'listens in' on the chemical messages that tell our cells how to multiply. The tool improves our understanding of how cancerous growth begins, and could identify new targets for cancer medications.
Scientists have reported the first observation of spin precession of spin currents flowing in a silicon nanowire transport channel, and determined spin lifetimes and corresponding spin diffusion lengths in these nanoscale spintronic devices.
A recent estimate suggested there are more than 600 different types of graphene, commercial organisations looking to work with the material can struggle to know where to start. To address this problem, The University of Manchester and the National Physical Laboratory (NPL) have joined forces by holding the Graphene UK Standardisation Workshop at the National Graphene Institute (NGI).
Researchers have developed a simple 'recipe' for combining multiple materials with single functions into a single material with multiple functions: movement, recall of movement and sensing - similar to muscles in animals. The materials could be used to make robotics far more efficient by replacing bulky devices with a single, smarter, life-like material.
