The lowest temperature, , where the specific heat is nonzero is introduced and is studied as a function of the dot radius. The value of approaches to the result for the free-space hydrogen atom for extremely small and also for large dot radii. The specific heat for two typical values of...
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...
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...

where\(\Delta E_{{\mathrm{H}}^ \ast }\)is the energy of hydrogen adsorption, and\(\Delta E_{{\mathrm{ZPE}}}\)is the difference in zero-point energy between the adsorbed states and the gas phase. The hydrogen adsorption site was confirmed by comparing the energy of hydrogen adsorption...
X-ray crystallography of a humanized 10G4 Fab fragment in complex with LTC4 revealed that binding induces a hook-like conformation within the hydrocarbon tail of the lipid arachidonic acid moiety. Specific hydrogen bonding to the LTC4 carboxylate groups further stabilized the complex, while a water...

(Fig.4b). These results suggest that Insig-2 is oxidizable and Cys215 is the major oxidation site. To determine whether Insig-2 stability is regulated by cellular redox, we transfected cells with Insig-2 followed by treatments with increasing concentrations of hydrogen peroxide (H2O2), an ...

PURPOSE:To perform specific heat measurement which is hardly affected by radiation loss by measuring the energy density at a place where the distribution of the energy density in a pulse beam emitted by a high-brightness light source is locally flat. CONSTITUTION:A heater 10 varies the temperature...
