Fine structure in swift heavy ion tracks in amorphous SiO2.
We report on the observation of a fine structure in ion tracks in amorphous SiO2 using small angle x-ray scattering measurements. Tracks were generated by high energy ion irradiation with Au and Xe between 27 MeV and 1.43 GeV. In agreement with molecular dynamics simulations, the tracks consist of a core characterized by a significant density deficit compared to unirradiated material, surrounde...
متن کاملLOW-ENERGY-ION ENHANCED DIFFUSION AT THE SURFACE OF METALS
Radiation enhanced diffusion at the surface of metals has been observed and studied for low-energy nitrogen ions at the surface of copper. The displacement of the target atoms during irradiation creates vacancies and other defects near the surface, thus enhancing the diffusion of implanted materials toward the surface and also into the solid. The mechanism has been studied here by a specia...
متن کاملThe low energy ion assisted control of interfacial structure: Ion incident energy effects
The properties of multilayered materials are often dependent upon their interfacial structure. For low temperature deposition processes where the structure is kinetically controlled, the interfacial roughness and the extent of interlayer mixing are primarily controlled by the adatom energy used in the deposition. Inert gas ion assistance during the growth process also enables manipulation of th...

دراین پروژه به بررسی مدل سازی خشک کردن مواد غذایی با استفاده از هوای خشک در خشک کن آزمایشگاهی نوع سینی دار پرداخته شده است. برای آنالیز انتقال رطوبت در طی خشک شدن به طریق جابجایی، یک مدل لایه نازک برای انتقال رطوبت، مبتنی بر معادله نفوذ فیک در نظر گفته شده است که شامل انتقال همزمان جرم و انرژی بین فاز جامد و گاز می باشد. پروفایل دما و رطوبت برای سه نوع ماده غذایی شامل سیب زمینی، سیب و موز در طی...
15 صفحه اولLow fluence swift heavy ion irradiation of amorphous germanium
Synchrotron based Small Angle X-ray Scattering (SAXS) give evidence of SHI irradiation induced ion-tracks in a-Ge. The scattering spectra of the ion-tracks can be fitted by using a model function of a cylindrical electron density distribution with an internal core shell structure. Core and shell are both of constant electron density but one being overthe other under-dense with respect to the su...
