Hydration reactions of sodiated and potassiated nucleic acid bases (uracil, thymine, cytosine, and adenine) produced by electrospray have been studied in a gas phase using the pulsed ion-beam high-pressure mass spectrometer. The thermochemical properties, ΔH(o)(n), ΔS(o)(n), and ΔG(o)(n), for the hydrated systems were obtained from hydration equilibrium measurement. The structural aspects of th...

The Sulfur-Iodide (SI) process has been investigated extensively as an alternate process to generate hydrogen through the thermo-chemical decomposition of water. The commercial viability of this process hinges on the durability and efficiency of heat exchangers/decomposers that operate at high temperatures under corrosive environments. In cooperation with the DOE and the University of Nevada, L...

Thermochemical multistep waterand CO2-splitting processes are promising options to face future energy problems. Particularly, the possible incorporation of solar power makes these processes sustainable and environmentally attractive since only water, CO2 and solar power are used; the concentrated solar energy is converted into storable and transportable fuels. One of the major barriers to techn...

Charcoals have been widely used by scientist to research the removal of contaminants from water and air. One key feature of charcoal is that it keeps macropores from the parent material - though anisotropically contracted - and can even develop meso- and micropores. However, the controlled thermochemical conversion of biomass into charcoal at laboratory scale normally requires special setups wh...

This article reviews the progress, challenges and opportunities in numerical modelling of thermal transport, thermochemical reactions and thermomechanics in high-temperature solar thermochemical systems. Continuum-scale models are presented in mathematical detail while highlighting the literature that uses them. The discussion is enhanced by selected examples of numerical studies of solar therm...

Abstract Recently, interest in on-site heat generation has increased due to injection of thermochemical fluids as a complex effect on well productivity. The method treatment with H 2 O while restoring and increasing the filtration characteristics bottomhole formation zone is relatively new insufficiently studied technology. article discusses key factors affecting exothermic decomposition this f...

The increase in the population of the planet and the rapid economic growth and, consequently, the high consumption of energy has created many environmental problems in the globe. Due to these reasons and the lack of renewability of these fossil fuels, there has been a steep trend towards the production of renewable fuels from natural sources, one of which is the production of energy from biomas...
