Degradation of phenolic acids by gamma radiation as model compounds of cork wastewaters [PDF]
The degradation by gamma radiation of four phenolic compounds (gallic acid, protocatechuic acid, vanillic acid and syringic acid) present in cork wastewaters was studied in several treatment conditions.

ABSTRACT Exposure to urban air pollution, particularly particulate matter (PM), has been correlated with an increased risk of neurodegenerative diseases, notably Alzheimer's and Parkinson's diseases. However, the mechanisms underlying the association between urban air pollution and neurodegenerative diseases remain unclear.

Nature's Starships. I. Observed Abundances and Relative Frequencies of Amino Acids in Meteorites [PDF]
The class of meteorites called carbonaceous chondrites are examples of material from the solar system which have been relatively unchanged from the time of their initial formation. These meteorites have been classified according to the temperatures and physical conditions of their parent planetesimals.

Meteoritic Abundances of Fatty Acids and Potential Reaction Pathways in Planetesimals [PDF]
The origin of fatty acids on the prebiotic Earth is important as they likely formed the encapsulating membranes of the first protocells. Carbon-rich meteorites (i.e., carbonaceous chondrites) such as Murchison and Tagish Lake are well known to contain these molecules, and their delivery to the early planet by intense early meteorite bombardments ...

Photoredox autocatalysis is revealed to access cyclic biaryl sulfonamides (BASNs) without an initial exogenous photocatalyst. While unveiling photoredox autocatalysis is important to the enrichment of basic research, this has also led to further practical applications such as rapid discovery of novel, potent and readily accessible photocatalyst ...
