A biochar derived from the pyrolysis of excess sludge of sewage treatment plant at 700 °C was used to remove phenanthrene and pyrene from aqueous solution. The adsorption equilibrium for phenanthrene and pyrene was achieved within 7.5 and 15 h, respectively. The adsorption kinetics of phenanthrene and pyrene were well fitted to pseudo-second-order model, and the isotherms were well fitted to Freundlich...
The incorporation of strain in order to improve mobility has become an important element in CMOS device scaling. In this work, we have developed a new moment-based model of extended defect kinetics and further studied the impact due to stress on the energies of impurities, point defects and particularly extended defects. We specifically look at point defect clusters which control transient enhanced...
