Polymeric graphitic carbon nitride materials (for simplicity: g-C(3)N(4)) have attracted much attention in recent years because of their similarity to graphene. They are composed of C, N, and some minor H content only. In contrast to graphenes, g-C(3)N(4)

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,

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,

Investigating New Reactivities Enabled by Polariton Photochemistry.
Journal of Physical Chemistry Letters, 2019We perform quantum dynamics simulations to investigate new chemical reactivities enabled by cavity quantum electrodynamics. The quantum light-matter interactions between the molecule and the quantized radiation mode inside an optical cavity create a set ...

Photochemistry of Surface Fresh Waters in the Framework of Climate Change.
Environmental Science and Technology, 2019Photochemical processes taking place in surface fresh waters play an important role in the transformation of biorecalcitrant pollutants and some natural compounds and in the inactivation of microorganisms.
