Abstract. This article, the eighth in series, presents kinetic and photochemical data sheets evaluated by IUPAC Task Group on Atmospheric Chemical Kinetic Data Evaluation. It covers gas-phase thermal reactions of organic species with four, or more, carbon atoms (? C4) available website 2021, including closed-shell HO NO3 radicals their photolysis. The present work is a continuation volume II (A...

This article, the sixth in the ACP journal series, presents data evaluated by the IUPAC Task Group on Atmospheric Chemical Kinetic Data Evaluation. It covers the heterogeneous processes involving liquid particles present in the atmosphere with an emphasis on those relevant for the upper troposphere/lower stratosphere and the marine boundary layer, for which uptake coefficients and adsorption pa...

This article, the fifth in the ACP journal series, presents data evaluated by the IUPAC Subcommittee on Gas Kinetic Data Evaluation for Atmospheric Chemistry. It covers the heterogeneous processes on surfaces of solid particles present in the atmosphere, for which uptake coefficients and adsorption parameters have been presented on the IUPAC website in 2010. The article consists of an introduct...

The IUPAC Subcommittee for Data Evaluation for Atmospheric Chemistry have extended the scope of the treatment of heterogenous reactions on this website. We are now in the process of replacing the data tables containing a compilation of uptake coefficient data for heterogeneous reactions of selected species with data sheets in which the relevant data for heterogeneous processes are evaluated and...

the use of twb has been developed in automotive industries because of it’s advantages such as reduction in weight, cost and fuel economy of vehicles. the main objective of the peresent work is to study the effects of weld zone, diffrence in surface coating and thickness ratio on the formability of twb composed of aisi 304, spcc and if steel sheets. it was found that the narrow weld zone has lit...

europium (eu) doped zno microsphere based nano-sheets were synthesized through hydrothermal method. effects of different concentrations of europium on structural and optical properties of zno nano-sheets were investigated in detail. prepared un-doped and eu-doped zno samples were characterized using x-ray diffraction (xrd), energy dispersive x-ray spectroscopy (edx), scanning electron microscop...

Various forms of representation are used to understand physics concepts. This study aims reveal the representations by students in summarizing their teaching materials. The observed include mathematical equations, verbal statements and graphs. participants were who attended lectures two academic years, namely 2016 2018. Students permitted freely write a summary lecture material that would be as...

The aim of retinal transplantation is to prevent blindness and to restore eyesight, i.e. to rescue photoreceptors or to replace damaged photoreceptors with the hope of re-establishing neural circuitry. A promising experimental paradigm is the sub-retinal transplantation of sheets of fetal retina, with or without its attached retinal pigment epithelium (RPE), into recipient rats with retinal deg...
