Diamond plates create nanostructures through pressure, not chemistry: Method is more ecological than chemical processes
Yet, in a current paper in Nature Communications, Sandia National Laboratories researcher Hongyou Fan and colleagues appear to have achieved a start toward that end.

Measuring the mass of 'massless' electrons: Taming graphene, Harvard-led researchers successfully measure collective mass of ‘massless’ electrons in motion
A schematic of the experimental setup. Ham and Yoon measured the change in phase of a microwave signal sent through the graphene.

Astronomers map space’s icy wastes
In space, ice forms by building up a ‘frost-like’ layer on dust grains at a temperature of -263 degrees Celsius. The layer that results is a bit like the frost that forms on a car windscreen on a (somewhat less) cold morning on Earth. In this image the dust layer is represented by the blue coloured molecules at the bottom of the image. Water molecules have two hydrogen atoms (shown here in white) and one oxygen atom (shown here in red). Here the ice forms without structure (so-called amorphous ice), quite unlike the more familiar cubes of ice that you might find in a drink. This results in pores forming in the ice - the big 'hole' in the middle of this simulation. The 'hole' here is nano-sized - about a million times smaller in diameter than the diameter of a human hair. Gases get trapped in these pores, which can have a profound effect on temperatures and densities in regions of star formation.

NASA Launches Earth Science Challenges with OpenNEX Cloud Data
NASA satellite data incorporated into OpenNEX include global views of drought conditions. Green regions in this map of July 2012 are areas with more vegetation than an average July (2000-2013); red regions have less vegetation than average. Regions in black have no data due to clouds and snow.

Titan's Building Blocks Might Pre-date Saturn
New research on the nitrogen in Titan's atmosphere indicates that the moon's raw materials might have been locked up in ices that condensed before Saturn began its formation.

One step to solar-cell efficiency: Rice University researchers’ chemical process may improve manufacturing
Rice University scientists have reduced to one step the process to turn silicon wafers into the black silicon used in solar cells. The advance could cut costs associated with the production of solar cells. Here, a cross section shows inverted pyramids etched into silicon by a chemical mixture over eight hours.
