TL;DR: In this article, the preparative and structural aspects of this very useful and protean photocycloaddition are reported. But they do not discuss the effect of UV irradiation on them.

TL;DR: In this article, the authors reviewed the historical steps of the mechanistic studies, based on fluorescence quenching, cyclization quantum yields measurement, the influence of dioxygen and solvents, they support a singlet state pathway; the dimerization rate constants are found to be generally high for reactions occurring within a few nanoseconds unless they are slowed down or inhibited by steric strain.

TL;DR: In this article, a new chemical modification of sugar cane bagasse and curaua fibres, consisting in a selective oxidation of lignin by chlorine dioxide and reacting some of the created unsaturated units (quinones or muconic derivatives) with furfuryl alcohol (FA), was used to create a fibre coating increasing compatibility between fibres and phenolic resins in composites.

TL;DR: In this paper, the inter and intramolecular photochemical reactions of 9-anthracenes in the absence of oxygen are discussed, and the mechanistic aspects are examined, next, in connection with the problem of excimer intermediacy.

TL;DR: This study shows that biobased composites with good properties can be prepared using a high proportion of materials obtained from natural resources using glyoxal, which is a dialdehyde obtained from several natural resources.
