Math-Phys-Chem Approaches to Life

Aging as the process in which the built-in entropy decreasing function worsens as internal time passes. Thus comes our definition, “life is a one way flow along the intrinsic time axis toward the ultimate heat death, of denumerably manymetabolic reactions, each at local equilibrium in view of homeostasis”. However, our disposition is not of reductionismic as have been most of approaches, but it...

Comment on "How to interpret Onsager cross terms in mixed ionic electronic conductors" by I. Riess, Phys. Chem. Chem. Phys., 2014, 16, 22513.

Here we show that the Onsager cross terms for ion-electron interactions are not an artifact, but the necessity to phenomenologically and completely describe the mass/charge transport of a mixed ionic-electronic conductor in terms of mobile charged components which are the only experimentally operable species. The use of an appropriate comprehensive defect model may help to reduce the cross term...

Comment on "Optical conversion of conical intersection to avoided crossing" by Y. Arasaki and K. Takatsuka, Phys. Chem. Chem. Phys., 2010, 12, 1239.

A recent paper in this journal proposed the conversion of conical intersections to avoided crossings by lowering the symmetry with an optical field. The article also claimed that the characters of nonadiabatic transitions caused by avoided crossings and conical intersections are qualitatively different. The present comment shows that this proposal and this claim result from an incorrect appreci...

Comment on "Density functional theory analysis of structural and electronic properties of orthorhombic perovskite CH3NH3PbI3" by Y. Wang et al., Phys. Chem. Chem. Phys., 2014, 16, 1424-1429.

Yun Wang et al. used density functional theory (DFT) to investigate the orthorhombic phase of CH3NH3PbI3, which has recently shown outstanding properties for photovoltaic applications. Whereas their analysis of ground state properties may represent a valuable contribution to understanding this class of materials, effects of spin-orbit coupling (SOC) cannot be overlooked as was shown in earlier ...
