Thermal water splitting by redox reactants could contribute to a hydrogen-based energy economy. The authors previously assessed and classified these thermo-chemical reactions. Mn3O4/MnO/NaMnO2 multi-step cycles were demonstrated have high potential. present research experimentally investigated the MnOx/Na2CO3 system both in an electric furnace concentrated solar at 775 825 °C, respectively, usi...

Introduction: Elevated levels of CRP are present among patients at risk for further first-ever myocardial infarction and stroke. It has been shown that after ischemic stroke, increased levels of CRP are associated with unfavorable outcomes. Methods: From 120 patients admitted to the emergency unit of our hospital with the diagnosis of stroke CRP, D-dimer and ferritin level was measured and the ...

The mechanism of heterogeneous catalysis taking into account the influence temperature is briefly considered in development concept "electron as a catalyst". Here catalytic cycle includes heat transfer and electron generation besides mass transfer. realised through electrons positive feedback loop. This involves Edison Seebeck thermoelectronic effects. supplemented with stage. stage generation....

The fabrication of many devices in modern technology requires techniques for growing thin films. As devices miniaturize, manufacturers will need to control thin film growth at the atomic level. Because many devices have challenging morphologies, thin films must be able to coat conformally on structures with high aspect ratios. Techniques based on atomic layer deposition (ALD), a special type of...
