The stability of MICE at different temperatures and the interaction of MICE with metal ions were confirmed using FT-IR spectroscopy. The formation of pyruvic acid from degradation of DAB followed pseudo-second-order rate kinetics and it was a spontaneous, exothermic process. The activation energy ...
we compared accurate measurements of D for five quartzites, two microcrystalline samples (chert and agate), chalcedony, and two partially crystalline opal specimens (of type opal-CT) with single-crystal quartz. Samples were characterized using infrared (IR) spectroscopy, electron microprobe analysis, o...

The strengths of intramolecular HH and HY hydrogen bonding between a ligating 2-aminopyridine NH group and a cis Ir-H bond or a cis halo group has been estimated (1.8-5.2 kcal/mol) in a series of compounds of general form [IrH2(Y)(2-C6H4NH2)(PPh 3)2]n+ (Y = H-, F-, Cl-...
Determination of pesticide residual levels in strawberry (Fragaria) by near﹊nfrared spectroscopy In this study, the development of IR based-prediction method for easy, fast and non-destructive detection of pesticide residue levels measured by reference... A Yazici,GY Tiryaki,H Ayvaz - 《Journal ...
The relative critical overview of indicators, which set norms to the drinking water and are used as background for regulatory instruments of the USA, the EU, the WHO, Ukraine and Russia, has been revealed. The analytical review of current problems in dri
14 Factors Affecting the Success of Dental Implants Carlos Nelson Elias Instituto Militar de Engenharia, Biomaterials Laboratory Rio de Janeiro, RJ, Brazil 1. Introduction Dental implants are fully placed in the bone in order to replace the natural root of the tooth and allow the installation of ...
Protein secondary structure analysis by Raman spectroscopy The protein secondary structure is the specific conformational structure that is formed by the polypeptide backbone through the hydrogen bond connection along a particular axis of circling or folding, mainly for the four structures including ɑ-heli...
