Formation mechanisms of spatially-directed zincblende gallium nitride nanocrystals

Gas-filled joints after oxy-helium saturation dive.

Though gas may be detected radiographically in joints this is c,nsidered to be a chance finding. Gas in joints after decompression from hyperbaric pressures has been ireported in animals (Gersh, 1946) but so far as we have been able to ascertain this has never before been noted in association with a particular dive in divers with or without symp,toms of decompression sickness. Ilt has been reco...

Gallium Nitride Photoconductive Detectors

Since 1994, the Applied Physics Laboratory has been collaborating with NASA Goddard Space Flight Center to develop photodetectors based on gallium nitride and aluminum gallium nitride material produced in the Milton S. Eisenhower Research and Technology Development Center. This article describes the results of our collaboration and highlights the development of gallium nitride photodetectors wi...
