Photochemical oxidant air pollution : peroxyacetyl nitrate (PAN) as an indicator of photochemical activity
Photochemical smog is formed by the interaction of sunlight with nitrogen oxides and hydrocarbons. These precursors are principally emitted by anthropogenic sources. As the major component of the photochemical oxidants is ozone, it is used as the indicator of photochemical smog and air quality …

A Model for the Chloroplast: A Study of the Photochemical and Spectral Properties of Pheophytin A Adsorbed to the Surface of Small Particles
… in influencing the nature and efficiency of the photochemical electron-transfer reactions of chlorophyll. This research has involved the study of a simple model for the chloroplast with the purpose of gaining some insight into this problem. It is known that chlorophyll and related molecules will …

Simulating the atmospheric primary and secondary organic aerosols
… the concentrations of OA during periods of high photochemical activity. To address the above issues new primary and secondary organic aerosol modules have been added to a three dimensional chemical transport model (PMCAMx) based on recent smog chamber studies. The new modeling framework is based …

Investigating the Molecular Composition of Rainwater and Secondary Organic Aerosol using Ultra-High Resolution Mass Spectrometry
… contained the most compounds due to increased photochemical activity and extra industrial emissions from North Africa respectively. All samples contained semi-volatile oxygenated organic aerosol and multiple organosulphates were tentatively identified. Continental samples contained …

Exploring the Function of Cytochrome c6A
… light harvesting balance was amplified, the photochemical activity of PSII was lower without c6A, and elevated NPQ levels suggested increased stress levels in the absence of c6A. These insights explain the observed growth penalty which could be caused by the altered light harvesting balance, …
