Photochemical smog is the result of complex chemistry taking place when sunlight irradiates the atmosphere laden with organic gases and nitrous oxides. High temperatures and bright sun light favour photochemical smog. The secondary pollutants, formed from the organic gases and nitrous oxides, are more aggressive and dangerous as the first pollutants. Secondary pollutants are O3, organic nitrate...

A new series of all-heterahomocalixarene-type structures was prepared. The new hetera[2(n)]metacyclophanes obtained contain a benzophenone moiety as photoactive component. Although both forms possess identical building blocks and differ only in ring size, they are markedly different in photochemical reactivity. The cyclophane size is the driving force for the photochemical behaviour of the benz...

The unique optical properties of the fluoropolymer microcapillary film (MCF) material combined with the extremely fast photoinactivation of Herpes HSV-1 virus, and photodegradation of indigo carmine, diclofenac and benzoylecgonine in the MCF array photoreactor, demonstrate a new, flexible and inexpensive platform for rapid photochemical transformations, high-throughput process analytics and pho...

Reactions of 1 ,Zdihydropyridines (la-c) and 1,4-dihydropyridines (2a-c) in the presence of benzyne (3) under thermal conditions, and in the case of (2c) under photochemical conditions, have been investigated. Benzyne acts as an oxidizing agent to convert dihydropyridine (la) and (2a) to the corresponding pyridine (4) or adds as a dienophile to (lb-c).

Nothofagus nitida (Phil.) Krasser (Nothofagaceae) regenerates under the canopy in microsites protected from high light. Nonetheless, it is common to find older saplings in clear areas and adults as emergent trees of the Chilean evergreen forest. We hypothesized that this shade to sun transition in N. nitida is supported by an increase in photochemical and non-photochemical energy dissipation ca...

BACKGROUND Non photochemical reduction of PQ pool and mobilization of LHCII between PSII and PSI are found to be linked under abiotic stress conditions. The interaction of non photochemical reduction of PQ pool and state transitions associated physiological changes are critically important under anaerobic condition in higher plants. METHODOLOGY/FINDINGS The present study focused on the effect...

PURPOSE Photochemical internalization is under development for improving macromolecular therapy by inducing photochemical damage to endocytic vesicles. This damage leads to the release of therapeutic macromolecules entrapped in endocytic vesicles into the cytosol. The macromolecules may in this way be able to interact with therapeutic targets instead of being degraded by lysosomal hydrolases. B...
