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 identified....

Solution-Based Synthesis of Functional Graphene

PSU researchers have developed techniques to covalently attach single and multiple layers of graphene sheets on substrates. The graphene can subsequently be functionalized for use in nanobiosensor applications. Procedures are being developed for the solution-based synthesis and functionalization of graphene sheets from graphite in a way that is straightforward,...

Nitrogen Dioxide Gas Sensor

PSU researchers have developed a new chemical gas sensor capable of detecting nitrogen dioxide (NO2) at levels less than 100ppb (two orders of magnitude more sensitive than current chemiluminescent based NOx sensors), having a dynamic linear range of parts per million to parts per billion, and a speed of detection of 60-120 seconds. Unlike existing...

New Dyes for Forensic Applications

Fingerprints are the most common and useful physical evidence for the apprehension and conviction of crime perpetrators. Reagents for the detection and enhancement of fingerprints are among the most useful tools in this regard. However, the available fluorogenic reagents for detecting and enhancing fingerprints left in blood have several associated...

Ambient Pressure NO2 Sensor

The measurement of nitrogen dioxide (NO2) is important to both environmental monitoring and to research of flame, combustion, and surface chemistry. Current methods and devices operate at very low, sub-ambient pressures, requiring a substantial pumping system and limiting their usefulness in applications in higher pressure environments where direct...
