Ebook "Photochemistry: A modern theoretical perspective" offers an introduction to photochemistry for students with a minimal background in physical chemistry and molecular quantum mechanics. The focus is from a theoretical perspective and highlights excited state dynamics. The authors, experienced lecturers, describe the main concepts in photochemical and photophysical processes that are used as a basis to interpret classical steady-state experimental results (essentially product branching ratios and quantum yields) and the most advanced time-resolved techniques.

Ebook "Reactions of solids with gases (Comprehensive chemical kinetics, Volume 21)" addresses collision energy transfer and the effects it has on gas phase reactions, particularly at low gas density. Such systems include combustion, industrial gas phase processes and atmospheric/environmental processes. The book also discusses The Master Equation to give a good overview of the mechanics underpinning unimolecular kinetics. This new volume will be of interest to researchers investigating gas phase processes which involve unimolecular reactions and the related intermolecular reactions.

One of the excellent methods for recovering waste heat from combustion furnaces is using regenerators. In this work, the heat transfer characteristics of the regenerators in a glass melting furnace are numerically and experimentally studied. A one-dimensional heat transfer model is proposed to investigate the heat transfer characteristics of real regenerators.

Intramolecular reorganization energy (RE) of molecules derived from the diketopyrrolopyrrole (DPP) unit has been studied using B3LYP/6-31G(d,p) theory. It was found that the replacement of the oxygen atoms with sulfur in the DPP unit led to a smaller RE for both the hole and electron transfer processes. One disadvantage of the sulfur replacement is the twist of the conjugated backbone, which might impair the π − π interactions in the solid state. The RE calculated from the adiabatic potential energy surfaces and that derived from the normal mode analysis agreed well for both systems.

The second major aim of this work is to understand the antioxidant mechanisms of the diphenylamines. The potential energy surfaces (PES) of reactions between the substituted diphenylamines with CH3OO• radical were calculated at M05-2X/6-311++G(d,p) level of theory. Rate constants for hydrogen atom transfer processes at the NH bond were also computed at the same level of theory using the conventional transition state theory (TST).

Cellular respiration is a catabolic pathway for producing adenosine triphosphate (ATP) and is the most efficient process through which cells harvest energy from consumed food. When cells undergo cellular respiration, they require a pathway to keep and transfer electrons (i.e., the electron transport chain).

In this work, Ce3+ and Sm3+ ions doped/co-doped Ca2Al2SiO7 (CAS) phosphors were prepared by solid state reaction method at high temperature. X-ray diffraction results showed that the prepared samples had tetragonal single phases with selected synthesis conditions. Energy transfer process of Ce3+/Sm3+ pair in CAS phosphor was studied by photoluminescence (PL) and photoluminescence excitation (PLE) spectra. Emission intensity of Ce3+ in Ca2Al2SiO7:xCe3+ , (1mol%) Sm3+ phosphors clearly varied with Ce3+ concentration; and reached to maximum value at the concentration of 2 (mol%).
