(Nanowerk News) Thin-film zeolite membranes with tiny, molecule-sized pores are one step closer to replacing the energy-intensive processes now used in industrial separations, a group of academic ...

Most solid materials, both those formed naturally and those fabricated for technological applications, are polycrystalline. In other words, they consist of a complex arrangement of grains within which ...

Mixed ionic–electronic conductors (MIECs) are widely used in semiconductors, electrochemical energy storage materials, electrodes of fuel cells and batteries, separation membranes and catalysts with ...

Researchers in the US, Germany, Singapore and Spain have developed a new technique to obtain images of grain-boundary defects in graphene by analysing the behaviour of surface plasmons. Their study ...

Engineering researchers demonstrate that graphene, even if stitched together from many small crystalline grains, is almost as strong as graphene in its perfect crystalline form. This resolves a ...

Materials engineers have found that the juncture at which graphene sheets meet does not compromise the material's strength. These so-called grain boundaries are so strong, in fact, that the sheets are ...

Hybrid perovskites are promising materials for the next generation of solar cells as they combine the benefits of both organic and inorganic materials. Currently, the efficiency of hybrid perovskite ...

(Top) Picture of thermal measurement setup in the Goodson lab, Stanford University. (bottom) The sample is placed on a high-precision stage and raster scanned to produce 2D images of the thermal ...

In the quest to design more efficient solar cells and light-emitting diodes (LEDs), a team of engineers has analyzed different types of defects in the semiconductor material that enables such devices ...
