Carbon Energy, EarlyView.Optimized ITO back contact with pre‐Ga supply growth and Ag incorporation suppresses GaOx formation and interface recombination in bifacial CIGS solar cells. The devices achieve 17.25% front and 5.77% rear efficiency, delivering record bifacial power density up to 32.26 mW cm−2 in 4T perovskite/CIGS tandem architectures under enhanced albedo ...

Dynamic Control of Nucleic Acids Self‐Assembly and Expression Using Photoswitches
Chemistry – A European Journal, EarlyView.We review here the recent progress made in the design of molecular photoswitches, and highlight their implementation for the dynamic control over nucleic acids self‐assembly and expression. ABSTRACT Synthetic nucleic acids have become readily available and now constitute versatile building blocks in materials science—where they can be used to engineer ...

Azo dyes decolourisation by ABTS-oxidases (Laccases) from a fungus from tropical tree [PDF]
, 2012 Lignin is an important constitute of the wood and thus the organism like fungi and insects growing on wood produce some extracellular lignolytic enzymes. In fungi these enzymes include different oxidases and peroxidases.

The Canadian Journal of Chemical Engineering, EarlyView.Abstract Free‐radical grafting of natural polymers often assumes that initiators only create active sites before monomer addition. We tested this by exposing sodium alginate to potassium persulphate (KPS) under typical grafting conditions without monomer (acrylamide).

Studies on the activation of azo-dyes into direct-acting genotoxic agents by enterococcus faecalis.
, 1995 The ability of the intestinal bacterium Enterococcus faecalis to reduce a range of azo dyeswas studied and the optimal pH and temperature for azoreductase activity were determined.The rate of dye reduction was highly variable between dyes.
