Nextgeneration August 9, 2002 Next-Generation Tagging and Tracking System The Department of Energy's (DOE's) Oak Ridge National Laboratory (ORNL) and a strategic partner are working to develop the next generation of tagging and tracking systems for both defense and commercial applications. The intent is to address a significant need that currently exists in the training and logistics areas to …

Photoacoustic Microcantilevers for Spectroscopy ORNL researchers invented a unique microcantilever design that can identify the chemical structure of minute sample materials using photoacoustic and photothermal spectroscopy. The design advances current technology, which cannot identify specific chemicals, and furthers the detection of vapors, cells, and tissues. The technology can also characteri…

Superhydrophobic Nanostructured Materials Make the World’s Most Water Repellent Surface Hydrophobic surfaces bind very weakly with water, which makes drops bead on the surface. A hydrophobic surface is one which has a contact angle greater than 90 degrees with a drop of water. Many commercially available polymers are in this class. A superhydrophobic surface has a contact angle greater than 150…

Monolithically compatible impedance measurement Description BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates generally to the field of remote sensors and sensing, and in particular, to integrated remote sensors and sensing. 2. Description of Related Art Many problems prevent wide-temperature range impedance measurements in harsh environments. Pri…

New Methods in Motion Tracking to Generate Motion-Corrected Tomographic Images High quality three-dimensional images from conventional MRI, CT, PET, or SPECT scans require that the subject being imaged remain stationary during the scan. Any motion during the scan significantly reduces the quality of the resulting images. Although sedation and physical restraint can be used to impede live subjec…
