Study on Clean Leather Deliming Process with Sulfonated Phthalic Magnesium Salt
Deliming Leather Cleaer Production Non-Ammonium Deliming Agents Sulfonated Phthalic Magnesium Salt
2011/11/23
Sulfonated phthalic magnesium salt (SPMS) was used in the leather deliming process. The deliming properties of SPMS was determined with the indicators such as the change of pH, content of NH4-N, COD o...
Elastic Tensor and Thermodynamic Property of Magnesium Silicate Perovskite from First-principles Calculations
Thermodynamic property Elastic property MgSiO3 perovskite
2012/4/5
The thermodynamic and elastic properties of magnesium silicate (MgSiO3) perovskite at high pressure are investigated with the quasi-harmonic Debye model and the first-principles method based on the de...
A grid of NLTE corrections for magnesium and calcium in late-type giant and supergiant stars: application to Gaia
formation radiative transfer stars late-type atmospheres abundances
2011/10/18
We investigate NLTE effects for magnesium and calcium in the atmospheres of late-type giant and supergiant stars. The aim of this paper is to provide a grid of NLTE/LTE equivalent width ratios W/W* of...
