Tuning Polymorphs using Pressure-Transmitting Media

Evaluations of pressure-transmitting media for cryogenic experiments with diamond anvil cell.

The fourteen kinds of pressure-transmitting media were evaluated by the ruby fluorescence method at room temperature, 77 K using the diamond anvil cell (DAC) up to 10 GPa in order to find appropriate media for use in low temperature physics. The investigated media are a 1:1 mixture by volume of Fluorinert FC-70 and FC-77, Daphne 7373 and 7474, NaCl, silicon oil (polydimethylsiloxane), Vaseline,...

High-pressure polymorphs of anatase TiO2

Theoretical compressibilities of high-pressure ZnTe polymorphs

We report the results of a theoretical study of structural, electronic, and pressure-induced phase transition properties in ZnTe. Total energies of several high-pressure polymorphs are calculated using the density functional theory ~DFT! formalism under the nonlocal approximation. Thermal effects are included by means of a nonempirical Debye-like model. In agreement with optical absorption data...

Diagnosing denture problems using pressure-indicating media.

Pressure-indicating media have more diverse applications than merely the identification of areas on the denture base that cause mucosal pressure and pain. The purpose of this article is to provide guidelines for optimal use of the media and to identify alternative uses that could be considered in daily practice.

Transmitting Plant Viruses Using Whiteflies

Whiteflies, Hemiptera: Aleyrodidae, Bemisia tabaci, a complex of morphologically indistinquishable species(5), are vectors of many plant viruses. Several genera of these whitefly-transmitted plant viruses (Begomovirus, Carlavirus, Crinivirus, Ipomovirus, Torradovirus) include several hundred species of emerging and economically significant pathogens of important food and fiber crops (reviewed b...
