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 ...

Plastic solar cells' new design promises bright future

Energy consumption is growing rapidly in the 21st century, with rising energy costs and sustainability issues greatly impacting the quality of human life. Harvesting energy directly from sunlight to generate electricity using ...

Inside the black box of iron oxide formation

From the splendorous red hues in the Grand Canyon to the mundane rust attacking a neglected bicycle, iron hydroxides are all around us. As a matter of fact, they are just as common as quartz, which is the most widely distributed ...

'Yolk-shell' design leads to world-record battery performance

(Phys.org)—SLAC and Stanford scientists have set a world record for energy storage, using a clever "yolk-shell" design to store five times more energy in the sulfur cathode of a rechargeable lithium-ion battery than is ...

Invention jet prints nanostructures with self-assembling material

A multi-institutional team of engineers has developed a new approach to the fabrication of nanostructures for the semiconductor and magnetic storage industries. This approach combines top-down advanced ink-jet printing technology ...

Research show mechanism behind wear at the atomic scale

(Phys.org)—Wear is a fact of life. As surfaces rub against one another, they break down and lose their original shape. With less material to start with and functionality that often depends critically on shape and surface ...
