TL;DR: The first version of the IUPAC technical report on chemical actinometers was published in Pure Appl Chem 61, 187-210 (1989) as mentioned in this paper, and since then some methods have been improved, procedures have been modified, and new substances have been proposed as chemical act-inometers.
Abstract: This document updates the first version of the IUPAC technical report on "Chemical actinometers" published in Pure Appl Chem 61, 187-210 (1989) Since then, some methods have been improved, procedures have been modified, and new substances have been proposed as chemical actinometers An actinometer is a chemical system or a physical device by which the number of photons in a beam absorbed into the defined space of a chemical reactor can be determined integrally or per time This compilation includes chemical actinometers for the gas, solid, microheterogeneous, and liquid phases, as well as for the use with pulsed lasers for the measurement of transient absorbances, including the quantum yield of phototransformation, as well as the literature for each of the actinometers The actinometers listed are for the use in the wavelength range from the UV to the red region of the spectrum A set of recommended standard procedures is also given Advantages and disadvantages are discussed regarding the use of chemical actinometers vs electronic devices for the measurement of the number of photons absorbed Procedures for the absolute measurement of incident photon flux by means of photodiodes are also discussed

TL;DR: The second edition of the Glossary of Terms Used in Photochemistry [Pure Appl. Chem. 68, 2223-2286 (1996); ] has been both corrected and updated as discussed by the authors.
Abstract: The second edition of the Glossary of Terms Used in Photochemistry [Pure Appl. Chem. 68, 2223-2286 (1996); ] has been both corrected and updated. Terms have been added related to molecular anisotropy, the use of polarized radiation, nonlinear optical phenomena, and the emerging field of computation of excited species. Some changes have been introduced in this "Glossary" regarding the terms related to radiation energy to make this collection fully compatible with internationally agreed-upon terms. Many links are included to various Web pages listing quantities relevant to the work of photochemists and scientists using photochemical tools.

TL;DR: A glossary of terms covering phenomena considered under the very wide terms photocatalysis and radiation catalysis is presented in this article, where a clear distinction is made between phenomena related to either photochemistry and photosynthesis or radiation chemistry and radiation catalysts.
Abstract: This glossary of terms covers phenomena considered under the very wide terms photocatalysis and radiation catalysis. A clear distinction is made between phenomena related to either photochemistry and photocatalysis or radiation chemistry and radiation catalysis. The term "radiation" is used here as embracing electromagnetic radiation of all wavelengths, but in general excluding fast-moving particles. Consistent definitions are given of terms in the areas mentioned above, as well as definitions of the most important parame- ters used for the quantitative description of the phenomena. Terms related to the up-scaling of photocatalytic processes for industrial applications have been included. This Glossary should be used together with the Glossary of terms used in photochemistry, 3 rd edition, IUPAC Recommendations 2006: (doi:10.1351/pac200779030293) as well as with the IUPAC Compendium of Chemical Terminology, 2 nd ed. (the "Gold Book" 2006-; doi:10.1351/gold- book), because many terms used in photocatalysis are defined in these documents.

TL;DR: A glossary that was prepared by the Photochemistry Commission of the Organic Chemistry Division of the International Union of Pure and Applied Chemistry during the period 1978-1985 is presented in this paper, which provides definitions of terms and symbols commonly used in the field in order to achieve consensus on the adoption of some definitions and on the abandonment of inadequate terms.

TL;DR: In this paper, the authors present a review of the current approaches for the heterogeneous photocatalytic reduction of CO2 on TiO2 and other metal oxide, oxynitride, sulfide, and phosphide semiconductors.
Abstract: Rising atmospheric levels of carbon dioxide and the depletion of fossil fuel reserves raise serious concerns about the ensuing effects on the global climate and future energy supply. Utilizing the abundant solar energy to convert CO2 into fuels such as methane or methanol could address both problems simultaneously as well as provide a convenient means of energy storage. In this Review, current approaches for the heterogeneous photocatalytic reduction of CO2 on TiO2 and other metal oxide, oxynitride, sulfide, and phosphide semiconductors are presented. Research in this field is focused primarily on the development of novel nanostructured photocatalytic materials and on the investigation of the mechanism of the process, from light absorption through charge separation and transport to CO2 reduction pathways. The measures used to quantify the efficiency of the process are also discussed in detail.

TL;DR: The second-order rate constants for oxidation by ozone vary over 10 orders of magnitude, between o 0.1 M 1 s 1 s -1 and about 7 − 10 9 M 1 S -1 s - 1 s − 1 as discussed by the authors.

TL;DR: This paper reviews the P. pastoris expression system: how it was developed, how it works, and what proteins have been produced and describes new promoters and auxotrophic marker/host strain combinations which extend the usefulness of the system.
Abstract: During the past 15 years, the methylotrophic yeast Pichia pastoris has developed into a highly successful system for the production of a variety of heterologous proteins. The increasing popularity of this particular expression system can be attributed to several factors, most importantly: (1) the simplicity of techniques needed for the molecular genetic manipulation of P. pastoris and their similarity to those of Saccharomyces cerevisiae, one of the most well-characterized experimental systems in modern biology; (2) the ability of P. pastoris to produce foreign proteins at high levels, either intracellularly or extracellularly; (3) the capability of performing many eukaryotic post-translational modifications, such as glycosylation, disulfide bond formation and proteolytic processing; and (4) the availability of the expression system as a commercially available kit. In this paper, we review the P. pastoris expression system: how it was developed, how it works, and what proteins have been produced. We also describe new promoters and auxotrophic marker/host strain combinations which extend the usefulness of the system.

TL;DR: A review of the known inorganic catalysts with a focus on structure-activity relationships is given in this article, where the first water splitting system based on TiO2 and Pt was proposed by Fujishima and Honda in 1972.
Abstract: Photochemical splitting of water into H2 and O2 using solar energy is a process of great economic and environmental interest. Since the discovery of the first water splitting system based on TiO2 and Pt in 1972 by Fujishima and Honda, over 130 inorganic materials have been discovered as catalysts for this reaction. This review discusses the known inorganic catalysts with a focus on structure–activity relationships.
