Method and Apparatus for Sample Analysis
PSU researchers have developed a novel way to collect, concentrate and analyze gas samples for analysis, primarily in environmental applications. By increasing pressure and performing analyses on a focused gas sample, this technology easily and cheaply enables continuous and real-time monitoring of air quality. Emission sources are more easily ide...

Shear-Force Ultrasonic Near-Field Microscope
The Shear-Force Ultrasonic Near-Field Microscope (SUNM) is a nanometrology tool for surface and subsurface materials characterization, including the dynamic behavior of fluid-like mesoscopic films confined between two sliding solid boundaries. By mechanically exciting the film and detecting the resulting sound emitted, the elastic properties of the...
