Vapor deposited multilayers consisting of a low electrical resistivity conductor sandwiched between ferromagnetic metals such as cobalt or nickel-iron alloys sometimes exhibit giant magnetoresistance ~GMR!. The GMR properties of these films are a sensitive function of structure and defects in the films and therefore depend upon the processing conditions used for their synthesis. A three-dimensi...

The energy available from the diet, which affects fat deposition in vivo, is a major factor in the expression of genes regulating fat deposition in the longissimus dorsi muscle. Providing high-energy diets to yaks might increase intramuscular fat deposition and fatty acid concentrations under a traditional grazing system in cold seasons. A total of fifteen adult castrated male yaks with an init...

We present a description of the effect of the surface roughness on the energy straggling associated to the energy loss distributions of protons transmitted through a self supported metallic thin foil. For this purpose we prepared a polycrystalline gold thin films using the standard sputtering method with different deposition rates. The statistics of the surface height distribution induced in th...

A simulation study of the energy released in air due to the development of an extensive air shower has been carried out using the CORSIKA code. The contributions to the energy release from different particle species and energies as well as the typical particle densities are investigated. Special care is taken of particles falling below the energy threshold of the simulation which contribute abo...

The spatial distribution of the energy deposited by kilovolt electrons moving through gaseous molecular nitrogen was measured. The range of electrons of initial energy 300 eV to 5 keY was obtained and can be expressed by the formula R = Kl + K2 EA 1 K3 EA 2. where R is the range, E is the initial energy of the electrons, and Kj,Aj are constants. The range, in this energy interval, is greater th...

In this study, energy and chemical interaction of ZnO and CdS surfaces interfaced with metal-organic framework (MOF), to improve their properties, have been investigated using density functional theory (DFT). Results show that reformation of structures by hybridation with MOF can increase their stability and improve their properties. Comparison of ZnO and CdS structures predict that deposition ...

The purpose of the research described in this article was to synthesize molybdenum nitride films with well-defined structures and stoichiometries using ion beam assisted deposition @AD). Approximately 400 nm thick films were prepared by the evaporative deposition of molybdenum while simultaneously bombarding the growing film with low energy (250-1000 eV) nitrogen ions. The effects of ion-to-ato...
