Entropies and Heat Capacities of Gaseous Selenium Molecules
The presumably cyclic molecules Ses, Se6 and Se; are the main constituents of saturated selenium vapor at temperatures up to 400 °C as well as of the vapor above freely subliming trigonal selenium, and cyclic Seg molecules can be prepared as various crystalline modifications [1], Small selenium rings are also discussed as constituents of liquid and amorphous selenium obtained by quenching the l...
متن کاملHeat capacity in proteins.
Heat capacity (Cp) is one of several major thermodynamic quantities commonly measured in proteins. With more than half a dozen definitions, it is the hardest of these quantities to understand in physical terms, but the richest in insight. There are many ramifications of observed Cp changes: The sign distinguishes apolar from polar solvation. It imparts a temperature (T) dependence to entropy an...
متن کاملHeat Capacity in Bits
The temperature T may be expressed as the rate of energy increase per unit increase in the state uncertainty under no-work conditions. The consequences of such a choice for heat capacities are explored. I show that the ratio of the total thermal energy E to kT is the multiplicity exponent ~log–log derivative of the multiplicity! with respect to energy, as well as the number of base-b units of m...
متن کاملHeat capacity of protein folding.
We construct a Hamiltonian for a single domain protein where the contact enthalpy and the chain entropy decrease linearly with the number of native contacts. The hydration effect upon protein unfolding is included by modeling water as ideal dipoles that are ordered around the unfolded surfaces, where the influence of these surfaces, covered with an "ice-like" shell of water, is represented by a...
متن کاملGaseous Flows and Heat Transfer through Micro- and Nano-channels
The overall object of this paper is a systematic study of gaseous flows and thermal transport in twodimensional microand nano-channels using direct simulation Monte Carlo (DSMC) method. In the flow study, a validation of DSMC code was conducted by simulating a continuum flow in microchannel and the results show that the discrepancy of friction coefficient from theoretical prediction is well bel...
