Hydrogen is seen as one of the important energy vectors of the next century. Hydrogen as an energy carrier, provides the potential for a sustainable development particularly in the transportation sector. A hydrogen fueled engine has the potential for substantially cleaner emissions than other internal...
Bentz (2007) qualitatively compares the heat capacity of this porewater phase with that of water ice, noting the unusually high specific heat capacity of bulk liquid water can be attributed to energy consumed in bending and breaking of mobile hydrogen bonds. In molecular-dynamics simulations, Qomi...

At low temperature, amorphous materials have low energy excitations that result in a heat capacity that is in excess of the Debye heat capacity calculated from the sound velocity. These excitations are ubiquitous to the glassy state and occur with roughly the same density for all glasses. The s...

The energy goes into breaking hydrogen bonds. It takes a lot of energy to make water increase in temperature. The reverse is true too; it takes a lot of energy to lower the temperature of water. Basically, water really doesn't want to change temperature. We're pretty lucky to be made ...
Hydrogen molecules produced by the action of radiation play the role of the “catalyst”, and H2O molecules formed in the secondary reactions are the “deactivated form of the catalyst”. Hydrogen atoms and hydrated electrons propagate the chain. Oxygen formed in both spurs and the secondary ...
