Carnegie Mellon University's Roberto R. Gil and Rongchao Jin have successfully used NMR to analyze the structure of infinitesimal gold nanoparticles, which could advance the development and use of the tiny particles in drug development. Their approach offers a significant advantage over routine methods for analyzing gold nanoparticles because it can determine whether the nanoparticles exist in a both right-handed and left-handed configuration, a phenomenon called chirality. Determining a...

Researchers Develop New Process with Porous Molecular Organic Frameworks (MOFs) - Relevant to the Production of Pharmaceuticals Researchers of Karlsruhe Institute of Technology (KIT) and Ruhr-Universität Bochum (RUB) have developed a flexible and efficient new process for the separation of enantiomers. Enantiomer separation is indispensable for the production of many pharmaceuticals. In their process, the scientists use porous molecular frameworks (MOFs) that are assembled...

Ancient Norse mariners used Icelandic rocks to help them navigate the ocean when the Sun and stars were obscured by clouds, according to a study published Wednesday in the Proceedings of the Royal Society A. Over a thousand years ago Vikings ventured thousands of miles from their home toward Iceland and Greenland, and possibly even as far as North America, centuries before Columbus, by reading the position of the Sun and stars, and by way of landmarks, currents and waves. Experts have...

A nanoscale game of "now you see it, now you don't" may contribute to the creation of metamaterials with useful optical properties that can be actively controlled, according to scientists at Rice University. A Rice laboratory led by chemist Stephan Link has discovered a way to use liquid crystals to control light scattered from gold nanorods. The researchers use voltage to sensitively manipulate the alignment of liquid crystal molecules that alternately block and reveal light from the...
