The first x-ray crystallography view of Martian soil. Obtained by the Chemistry and Mineralogy (CheMin) experiment on NASA's Curiosity rover, these data reveal crystalline feldspar, pyroxenes and olivine mixed with some amorphous (non-crystalline) material. The soil sample is similar to volcanic soils in Hawaii.

AFM micrograph of 2D S-layers assembled on mica shows two different pathways to crystalization, one in which the domans are 2-3 nanometers taller (white circles). Height differences, measured along the dotted black line, were the result of kinetic trapping.

This shows the new all-carbon solar cell consists of a photoactive layer, which absorbs sunlight, sandwiched between two electrodes.

Georgia Tech Professor Andrei Fedorov demonstrates the electron beam induced deposition (EBID) system used to create graphitic nanojoints to multi-walled carbon nanotubes.

New research funded by NLSI theorizes that our early Earth and moon were perhaps created in a different manner than has previously been believed.

First X-ray View of Martian Soil
This graphic shows results of the first analysis of Martian soil by the Chemistry and Mineralogy (CheMin) experiment on NASA's Curiosity rover. The image reveals the presence of crystalline feldspar, pyroxenes and olivine mixed with some amorphous (non-crystalline) material. The soil sample, taken from a wind-blown deposit within Gale Crater, where the rover landed, is similar to volcanic soils in Hawaii. The colors in the graphic represent the intensity of the X-rays, with red being the most intense.

This image shows the size-dependent extraction of particles. The fluorescent image indicates trapping of larger particles while smaller particles pass through.
