Steam-Stripping for Regeneration of Supported Amine-Based CO2 Adsorbents
Here, a practical desorption process for supported amine adsorbents, steam-stripping, is demonstrated for the first time.
-
An Integrated Field Emission Array for Ion Desorption
Methods were developed to fabricate tip arrays with integrated gate electrodes, separated from the substrate with sufficient dielectric to sustain high voltages.

Inclined Dislocation-Pair Relaxation Mechanism in Homoepitaxial Green GaInN/GaN Light-Emitting Diodes
The creation of symmetrical pairs of inclined dislocations was observed in the GaInN/GaN quantum wells (QWs) of c-axis grown green light-emitting diodes (LEDs) on low-defect density bulk GaN substrate, but not…
