A recently published study gives a vivid example of unusual chemical reactivity found in the reactions with organogold complexes. Using the complex of modern physical methods joined with computational studies, the authors proposed reaction mechanism, where a molecule of acetic acid serves as a proton shuttle, transferring the hydrogen atom between the reaction centers.

Mimicking the texture found on the highly antireflective surfaces of the compound eyes of moths, researchers use block copolymer self assembly to produce precise and tunable nanotextured designs in the range of about 20 nm across macroscopic silicon solar cells. This nanoscale texturing imparts broadband antireflection properties and significantly enhances performance compared with typical antireflection coatings.
