A new formulation of the PCM solvation method: PCM-QINTn

Theoretical Chemistry Accounts: Theory, Computation, and Modeling (Theoretica Chimica Acta), 1997
A new formulation of the PCM electrostatic solution problem is proposed. Through a new derivation of the PCM-CLSn expression we propose an interpolation formula that improved the convergence: PCM-QINTn. All the available formulations are applied to the evaluation of the electrostatic component of the free energy of solvation for some molecular systems.

Thermal management of metal roof building using phase change material (PCM)

, 2021
The energy consumption of the buildings for cooling, especially during the days of high solar exposure is large due to the increased indoor temperature. The roof of the building contributes more for this cause by allowing a large quantity of heat during ...

The PCM Model

2013
This chapter introduces to the basic definitions of the PCM model for a molecular solute. The basic electrostatic problem for the determination of the solute-solvent interaction is described within the Integral Equation Formalism (IEF-PCM), and the QM problem associated to the effective Hamiltonian of the molecular solute is formulated in terms of a ...
