Thermochemical hydrogen-deuterium isotope effects
"The heats of solution at 25.0 ± 0. 1°C for each member of hydrogen-deuterium isotopic pairs (chloroform/chloroform-d, acetone/acetone-d₆, methanol/methanol-d₁, ethanol/ethanol-d₁, and water/heavy water) have been determined as a function of molality in a variety of solvents. The heats for most of …

Salt hydrates for thermochemical energy storage
… of renewable energy sources. In particular, thermochemical energy storage has a high energy storage density, extended storage period and minimal heat losses. Anhydrous salts when reacted with water vapour in air are hydrated and generate heat. Salt hydrates have often been chosen for space …

Optimal Curing for Thermoset Matrix Composites: Thermochemical and Consolidation Considerations
A finite element method is then developed to solve two-dimensional consolidation problems. The consolidation governing equations, one for solid stress and one for fluid pressure, are derived using a local volume averaging approach, and they are strongly coupled. A special anisotropic hyperelastic …

Understanding Mercury's Thermochemical Evolution Using a Geochemical and Geophysical Lens
Mercury is the most mysterious planet in the inner Solar System, suggested by observations from the MESSENGER mission. These observations shine a light on potential processes occurring within Mercury as it evolved over time. Scientific instruments aboard MESSENGER indicate that Mercury has a very …

Modified Nafion membranes for hydrogen production in Cu-Cl thermochemical cycle
The decomposition of water by a thermochemical cycle is a promising green method of producing hydrogen on a large scale. A thermochemical cycle is a combination of thermal and chemical reactions that ultimately leads to splitting water into hydrogen and oxygen. The Cu-Cl cycle, which is one of the …
