in). This custom was also known in France and was eventually transported to French Canada. In Germany old folk traditions recommended that horses be led into flowing waters on Easter Sunday as a means of insuring their good health (see alsoGermany, Easter and Holy Week in). Folk traditions ...
2O)--Complex]]>By means of an "ab initio" all electron treatment of the I-/H2O complex in various geometrical arrangements, it has been attempted to derive some arguments for the general discussion about the phenomenon of negative solvation, based on the background of quantum chemistry. The...
The interaction of water molecules with a polycrystalline V 2O 5 surface has been investigated both by means of a semi-empirical quantum chemistry computational method and by temperature-programmed desorption (TPD). From the TPD desorption spectra, it was found that water desorbed from the V 2O...

CH4―H2O体系流体包裹体研究对含油气盆地流体分析和成矿流体研究都有重要的意义。本文详细介绍了H2O、CH4和CH4―H2O体系的拉曼光谱特征及分子作用,分析了CH4―H2O体系热力学特征,同时对CH4―H2O体系流体包裹体拉曼光谱定量分析和计算的方法及步骤进行了叙述。利用人工合成
The kinetics of the solid-phase interaction in the system α-Fe-CuCl2. 2H2O was studied by means of Mössbauer spectroscopy. It was established that compounds of divalent and trivalent iron were formed by diffusion controlled chemical reactions. The experimental results were described by the Jurav...
nThbies synthesized means, that in a wide temperature range this big uncertainty in tem- perature has no significant effect on the validity of the results of this study. A ruby chip was inserted in the sample and the pressure determined from the peak wavelength of the R1 ruby fluorescence ...
Investigation of the vaporization of BaUO3 by means of mass spectrometry An investigation of the vaporization of BaUO3 has been carried out for the first time by means of Knudsen effusion mass spectrometry in the temperature ran... Michio,Yamawaki,and,... - 《Journal of Nuclear Materials》 被...
Moreover, PFAS are also still partially bound to soil particles or present in historical soil contamination. This means a restriction will only have a positive impact on groundwater quality in the much longer term. Therefore, by limiting production and use now, we can avoid a bigger problem ...
Ferrous succinate tetrahydrate (FeC 4H 4O 4·4H 2O) is prepared and its thermal decomposition is studied by means of simultaneous thermal analysis (TGA, DTA, DTG) curves supplemented with two probe d.c. electricial conductivity measurements under the atmospheres of static air, dynamic nitrogen ...
