3D 'printouts' at the nanoscale using self-assembling DNA structures

The new technique makes it possible to synthesize 3D DNA origami structures that are also able to tolerate the low salt concentrations inside the body, which opens the way for completely new biological applications of DNA nanotechnology. The design process is also highly automated, which enables the creation of synthetic DNA nanostructures of remarkable complexity.

Acetic acid as a proton shuttle in gold chemistry

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.

Illuminating the electronic properties of graphene

Researchers have shown that both the carrier mobility and the carrier density of graphene can be measured in a spatially resolved and non-destructive way - providing 'maps' of the electronic properties critical for the successful use of graphene in photovoltaics, electronics, spintronics and optics - using terahertz radiation and doing away with the need to fabricate devices.

Graphene - from science fundamentals to low-cost production

Keynote presentations on the third day of Graphene Week 2015 offered an eclectic mix of fundamental science and practical chemical engineering. Here we report briefly on each of the talks, beginning with an introduction to optoelectronics in 2D semiconductors and heterostructures, and concluding with an outline of a highly promising 'kitchen sink' approach to graphene production.

Nanocages offer new direction in sustainable catalyst design

Engineers have developed a new approach to structuring the catalysts used in essential reactions in the chemical and energy fields. The advance offers a pathway for industries to wean themselves off of platinum, one of the scarcest metals in the earth's crust.

Artificial moth eyes enhance the performance of silicon solar cells

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.
