We report a quantitative measurement of the pressure effect on melting point elevation of encapsulated nanoparticles without epitaxial interfaces. By means of in situ x-ray diffraction, a substantial melting point elevation of about 15 K in encapsulated Al nanoparticles in Al2O3 shells without epitaxial interfaces was observed. Meanwhile, a pressure buildup of about 0.25 GPa on the Al nanoparti...

The problem of unbounded uniaxial chiral omega media in the presence of both static electric and magnetic point charges is investigated. For this purpose scalar electric and magnetic potentials in these media are introduced. Using these potentials, the corresponding electric and magnetic fields are determined. The similar problem of static electric and magnetic current sources with the goal of ...

Mercury (Hg) is a global pollutant and poses a worldwide concern due to its high toxicity. Guizhou province is recognized as a heavily Hg-polluted area in China due to both the special geochemical background and human activities. Here an integrated overview of current knowledge on the behavior of Hg in environments, as well as human health risk with respect to Hg contaminations in Guizhou was p...
