Geoengineering: Whiter Skies?

One proposed side effect of geoengineering with stratospheric sulfate aerosols is sky whitening during the day and afterglows near sunset, as is seen after large volcanic eruptions. Sulfate aerosols in the stratosphere would increase diffuse light received at the surface, but with a non-uniform spectral distribution. We use a radiative transfer model to calculate spectral …

Boulder Ionics liquid electrolytes could double storage of ultracapacitors and improve batteries by up to ten times

Boulder Ionics’ ionic-liquid-based electrolytes enable a new generation of energy storage devices with superior performance, improved safety and lower costs. The company’s novel high-throughput synthesis process produces electrochemical-grade materials in minutes rather than days. This dramatic reduction in processing time enables a very low capital cost for the production equipment, minimizes labor costs, and improves …

South Korea Funds Graphene Commercialization

South Korea has approved a roadmap for graphene commercialization with $200 million budget for the next 6 years. They are also looking at a research institute that they would fund with $200-300 million per year. Korean government has approved a plan for commercializing graphene technologies, including; 1) graphene-based touch panels 2) organic light-emitting diodes (OLEDs) …

3 nanometer by 7 nm DNA Origami Tiles are Pixels in any 310 Pixel Shape

Nature – Complex shapes self-assembled from single-stranded DNA tiles Programmed self-assembly of strands of nucleic acid has proved highly effective for creating a wide range of structures with desired shapes. A particularly successful implementation is DNA origami, in which a long scaffold strand is folded by hundreds of short auxiliary strands into a complex shape. …
