Nonlinear phenomena in screening of highly charged grains in plasmas
Nonlinear effects in screening a highZ grain immersed in a plasma background were investigated by means of microscopic Monte-Carlo simulations and within the Poisson-Boltzmann theory. A distinct difference from the linear Debye-Hückel approximation was detected in the case of a strong plasma-grain coupling. It effected in the accumulation of the induced plasma charge on the grain surface, accom...

چکیده پلاتین، فلزی نجیب، پایدار و گران قیمت با خاصیت کاتالیزوری زیاد است که کاربرد های صنعتی فراوانی دارد. کمپلکس های پلاتین(ii) به عنوان دارو های ضد سرطان شناخته شدند و در شیمی درمانی بیماران سرطانی کاربرد دارند. خاصیت کاتالیزوری و عملکرد گزینشی پلاتین مستقیماً به اندازه و- شکل ماده ی پلاتینی بستگی دارد. بعضی از نانو ذرات فلزی در سطح مشترک مایع- مایع سنتز شده اند، اما نانو ساختار های پلاتین ب...

متن کاملNUMERICAL SIMULATIONS OF THE PHASE TRANSITIONS IN CLUSTERS
We have studied the phase transitions in atomic clusters by molecular dynamics simulation, assuming Lennard-Jones interatomic pair potential. Calculations are performed by DAP parallel computer. The results are analyzed by simulating their orientational distribution plots (dot-plot), and neutron diffraction patterns. It is shown that all the main features of the bulk phase transitions are e...
