Non-linear model of impurity diffusion in nanoporous materials upon ultrasonic treatment
Non-linear theory of diffusion of impurities in porous materials upon ultrasonic treatment is described. It is shown that at a defined value of deformation amplitude, an average concentration of vacancies and temperature as a result of the effect of ultrasound possibly leads to the formation of nano...

Показано, що при певному значеннi амплiтуди деформацiї, середньої концентрацiї вакансiй та температури в результатi впливу ультразвуку можливе формування нанокластерiв вакансiй та їх перiодичних утворень в поруватих матерiалах. Показано, що при температурi, меншiй за деяке критичне значення, у поруватих структурах спостерiгається значне зростання коефiцiєнта дифузiї. 2014 Article Non-linear model of impurity diffusion in nanoporous materials upon ultrasonic treatment / R.M.

| description |
Non-linear theory of diffusion of impurities in porous materials upon ultrasonic treatment is described. It is shown that at a defined value of deformation amplitude, an average concentration of vacancies and temperature as a result of the effect of ultrasound possibly leads to the formation of nanoclusters of vacancies and to their periodic educations in porous materials. It is shown that at a temperature smaller than some critical value, a significant growth of a diffusion coefficient is observed in porous materials. |
