Nanowires give 'solar fuel cell' efficiency a tenfold boost

A solar cell that produces fuel rather than electricity. Researchers at Eindhoven University of Technology (TU/e) and FOM Foundation today present a very promising prototype of this in the journal Nature Communications. The ...

Polymer mold makes perfect silicon nanostructures

Using molds to shape things is as old as humanity. In the Bronze Age, the copper-tin alloy was melted and cast into weapons in ceramic molds. Today, injection and extrusion molding shape hot liquids into everything from car ...

Printing silicon on paper, with lasers

In seeking to develop the next generation of micro-electronic transistors, researchers have long sought to find the next best thing to replace silicon. To this end, a wealth of recent research into fully flexible electronic ...

Engineers use liquid drops to make solids stiffer

(Phys.org)—Engineers at Yale University have discovered that the stiffness of liquid drops embedded in solids has something in common with Goldilocks: While large drops of liquids are softer than the solid that surrounds ...

Silicone liquid crystal stiffens with repeated compression

(Phys.org) —Squeeze a piece of silicone and it quickly returns to its original shape, as squishy as ever. But scientists at Rice University have discovered that the liquid crystal phase of silicone becomes 90 percent stiffer ...

Surface structure controls liquid spreading

Researchers at Aalto University have developed a purely geometric surface structure that is able to stop and control the spreading of liquids on different types of surfaces. The structure has an undercut edge that works for ...

Low density of Earth's core due to oxygen and silicon impurities

During accretion and differentiation of the Earth, chemical interactions in a silicate magma ocean and liquid iron drove silicon and oxygen impurities into what went on to become the liquid outer core. Contrasting with previous ...
