A detailed nanomechanical study of mechanical degradation processes in silicon structures containing varying levels of lithium ions offers good news for researchers attempting to develop reliable next-generation rechargeable batteries using silicon-based electrodes.
Cornell University, in partnership with Memorial Sloan Kettering Cancer Center, is opening a new $10 million Center of Cancer Nanotechnology Excellence that brings together scientists, engineers, biologists and physicians to develop and translate new cancer care applications based on nanotechnology.
Crucial to silicon semidconductor applications is the ability to 'dope' the semiconductor; which is to say, by controllably adding impurity atoms to a semiconductor, one can continuously vary its electronic and optical properties. Scientists now have demonstrated for the first time, a unique nanoscale analogue.
Germanium defects in a diamond crystal lattice act as a reliable source for single photons, new research shows. The results provide a promising new route to building components for quantum cryptography and biomarkers.
Biomedical engineers are using low-energy, ultrafast laser technology to make high-resolution, 3-D structures in silk protein hydrogels. The laser-based micropatterning represents a new approach to customized engineering of tissue and biomedical implants.
Researchers developed a simple method for producing a palladium-based nanomaterial that can spur the breakdown of formic acid into hydrogen and carbon dioxide. Its efficiency far exceeded that of any other reported heterogeneous catalysts, they say.
The researchers designed a new type of nanocarrier based on the biocompatible molecule poly(ethylene glycol), or PEG, that releases its cargo only in targeted immune cells. The nanocarrier degrades when it encounters the acidic part of these cells, simultaneously releasing the allergen and getting rid of the packaging.
Chemists have fabricated a novel nanosheet-based photonic crystal that changes color in response to moisture. The new material could form the basis for humidity-sensitive contactless control of interactive screens on digital devices.
