The formation, properties and impact of secondary organic aerosol: current and emerging issues [PDF]

, 2009
Secondary organic aerosol (SOA) accounts for a significant fraction of ambient tropospheric aerosol and a detailed knowledge of the formation, properties and transformation of SOA is therefore required to evaluate its impact on atmospheric processes ...

Photochemical Cyclization of Tertiary Buta‐2,3‐dienamides to β‐Lactams Upon Triplet Energy Transfer

Angewandte Chemie, EarlyView.
Energy transfer is the key to the successful photocyclization of the title compounds to 3,4‐disubstituted 2‐azetidinones. If the substituent at the nitrogen atom is primary (R2 = H), trans products are formed exclusively. The triplet state of xanthen‐9‐one (XT) was found to be quenched by an allene amide (R, R2 = H, R1 = Bn, and R3 = Ph) with a ...

Photochemical Approaches to Complex Chemotypes: Applications in Natural Product Synthesis. [PDF]

, 2016
The use of photochemical transformations is a powerful strategy that allows for the formation of a high degree of molecular complexity from relatively simple building blocks in a single step. A central feature of all light-promoted transformations is the

An Overview of Polyphenols and Color Chemistry in Cocoa

AgriFood: Journal of Agricultural Products for Food, EarlyView.
Cocoa polyphenols have been traditionally known for their beneficial properties in human health. However, less is known about their other impacts on cocoa processing. This review highlights current discoveries in the role of polyphenols in the formation of color in cocoa.

Aloe vera–Based Green Synthesis of Silver Nanoparticles With Characterization, Potent Antibacterial and Antioxidant Properties

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Green synthesis has emerged as a suitable alternative to the traditional method for manufacturing nanoparticles (NPs) as it provides a safer, sustainable, healthy, and environmental path for the NPs synthesis. Silver nanoparticles (AgNPs) were prepared using a green method with locally sourced Aloe vera leaf extract.
