 | A light-transmitting compound that could one day be used in high-efficiency fiber optics and sensors that detect biological and chemical weapons at long distance almost went undiscovered by scientists because its structure was too difficult to examine. ...> Full Article |
Researchers have cast doubt on existing chemistry theory and brought microwave spectroscopy into the Digital Age with a unique new technique that measures the way that molecules change their geometric shapes.

 | New research demonstrates that novel probe technology based on flexible membranes can replace conventional atomic force microscopy (AFM) cantilevers for applications such as fast topographic imaging, quantitative material characterization and single molecule mechanics measurements. ...> Full Article |
Finding a simple and convenient technique that combines nanoscale structural measurements and chemical identification has been an elusive goal. With current analytical instruments, spatial resolution is too low, signal-to-noise ratio too poor, sample preparation too complex or sample size too large to be of good service.

A new instrument can covertly detect chemical plumes at great distances and may help thwart future chemical or nuclear-based terrorist attacks. The technology has a number of other uses, as well, from detecting environmental pollution to determining the extent of tissue damage in burn victims without physical contact.
