Weathering will cause the proportion of chemical composition ancient glass products to change, thereby affecting classification judgment type. In order reasonably analyze content products, this paper provides a reference for studying change trend weathering by exploring whether appearance cultural relics affects and law. According relationship between surface ornamentation, color type, linear r...

By coupling two different magnetic materials inside a single composite nanoparticle, the shape of the magnetic hysteresis can be engineered to meet the requirements of specific applications. Sandwich-like composite nanoparticles composed of a hard-magnetic Ba-hexaferrite (BaFe12O19) platelet core in between two soft-magnetic spinel iron oxide maghemite (γ-Fe2O3) layers were synthesized using a ...

The Large Plasma Device at the University of California, Los Angeles has recently been upgraded. The plasma is now 18 m long the device is 22 m long and is designed to produce a 0.36 T axial magnetic field. Its plasma source has also been upgraded, incorporating a 1 m square heater, a 72 cm diameter cathode and anode, and associated heat shields and reflectors. The barium oxide coated cathode i...

nanocrystalline particles of barium hexaferrite has been prepared by the sol–gel auto- combustion method using iron and barium nitrate with a ba:fe molar ratio of 1:10. the effect of fuel such as citric acid and aspartic acid was investigated on the structure and magnetic properties of nanoparticles. the results revealed that the formation of barium hexaferritefine particles is influenced by mo...

Chemical solution deposition (CSD) provides a low-cost, versatile approach for processing of thin and ultrathin ferroelectric films, as well as short and high aspect ratio ferroelectric nanostructures. This review discusses the state of the art in the processing of ferroelectric oxide thin films and nanostructures by CSD, with special emphasis on nucleation and growth phenomena. The effects of ...

Barium studies investigations (barium swallow, barium meal and barium enema) are the basic routine radiological examination, where barium sulphate suspension is introduced to enhance image contrast of gastrointestinal tracts. The aim of this study was to quantify the patients' radiation doses during barium studies and to estimate the organ equivalent dose and effective dose with those procedure...
