Temperature impact on nitrification and bacterial growth kinetics in acclimating recirculating aquaculture systems biofilters
This project assessed short-term temperature effects on total ammonia nitrogen (TAN) utilization rates in a batch laboratory-scale recirculating system. The tank system was designed for experiments on short term steady state and diurnal temperatures. A set of numerical models was developed to …

Growth kinetics and doping of gallium nitride grown by rf-plasma assisted molecular beam epitaxy
A reduced rate for growth of GaN by plasma-assisted molecular beam epitaxy often limits growth to temperatures less than 750°C, with the reduction significantly larger than thermal decomposition rates. Conditions producing a flux consisting predominantly of either atomic nitrogen or nitrogen …

Silicon (011) and Silicon Germanium (011) Gas-Source Molecular Beam Epitaxy: Surface Reconstructions, Growth Kinetics, and Germanium Segregation
Ge surface segregation occurs during Si1--xGex(011) GS-MBE. Ge surface coverages thetaGe increase with x, ranging from 0.27 to 0.74 ML for x = 0.04--0.20. At a given film composition, theta Ge decreases with decreasing Ts due to the corresponding increase in the fraction of H-bonded Si surface …
