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.
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.
