An international team of scientists has succeeded in designing the world's first triply twisted molecule. Because of their peculiar quantum mechanical properties these structures are interesting for applications in molecular electronics and optoelectronics.
Using molecules of DNA like an architectural scaffold, scientists have developed a 3-D artificial enzyme cascade that mimics an important biochemical pathway that could prove important for future biomedical and energy applications.
Through a combination of high-resolution cryo-electron microscopy (cryo-EM) and new methodology for image analysis and structure interpretation, researchers have produced images of microtubule assembly and disassembly at the unprecedented resolution of 5 angstroms. Among other insights, these observations provide the first explanation of Taxol's success as a cancer chemotherapy agent.
Researchers have succeeded in measuring a previously unknown but essential property - thermal conductivity - of an ultra-thin material that is expected to play a major role in the fast-emerging field of nanoelectronics.
In response to requests from the semiconductor industry, researchers have demonstrated that atomic force microscope (AFM) probe tips made from its near-perfect gallium nitride nanowires are superior in many respects to standard silicon or platinum tips in measurements of critical importance to microchip fabrication, nanobiotechnology, and other endeavors.
