Photochemical & Photobiological Sciences, 2008
The use of a confined space in which to carry out reactions has proven popular in recent years, as demonstrated by the large volume of work published on 'molecular microreactors' such as zeolites, micelles and nanoparticles. This article looks at reactions in microstructured reactors, also known as microchannelled reactors or microreactors. In general,

The breadth of scientific and technological interests in the general topic of photochemistry is truly enormous and includes, for example, such diverse areas as microelectronics, atmospheric chemistry, organic synthesis, non-conventional photoimaging, photosynthesis, solar energy conversion, polymer technologies, and spectroscopy.

PHOTOCHEMISTRY OF RETINOCHROME
Photochemistry and Photobiology, 1981Abstract— Retinochrome is a photopigment found in the visual cells of cephalopods. It has been considered to act as a supplier of the 11‐cis‐retinal required for synthesis of rhodopsin, because its all‐trans chromophore is isomerized to 11‐cis form in the light.

The only action of light on the pigment of cone vision, iodopsin, as on the rod pigment rhodopsin, is to isomerize its chromophore from 11-cis to all-trans. All further changes are “dark” consequences of this one light reaction. Although this reaction initiates bleaching, its immediate product is a more intense pigment. At low temperatures in the dark,

Photochemistry in Nature and Applied Photochemistry
2016Several photochemical reactions of organic compounds are occurring in nature for the evolution of life and their existence on earth. Such evolutionary processes of life have been brought about by photochemical reactions of organic molecules. Among these photochemical reactions, photosynthesis of plants, vision of animals and depletion of stratospheric ...

IN the course of an investigation of the ultra-violet irradiation of solid films of uracil and thymine1, certain inconsistencies were observed in the irradiation of thymine films which were unexplainable at the time and therefore not reported. Information now available has led to an investigation of the influence of humidity, more properly the vapour ...

Le spectre d'absorption, les caracteristiques luminescentes et photochimiques de la riboflavine sont presentes. L'interpretation des donnees experimentales d'autres auteurs sur la decomposition photochimique de l'eau sensibilisee par la riboflavine est critiquee.
