Ultrasonic technique discloses the identity of graphite

A group of scientists from Osaka University, in cooperation with Kaneka Corporation, evaluated the interplanar bond strength of graphene by measuring the elastic constant of graphite, demonstrating that the elastic constant ...

Untwisting plastics for charging Internet-of-Things devices

Untwisting chains of atoms within a plastic polymer improves its ability to conduct electricity, according to a report by researchers, led by Nagoya University applied physicist Hisaaki Tanaka, in the journal Science Advances. ...

Groovy key to nanotubes in 2-D

Ultrathin carbon nanotubes crystals could have wonderous uses, like converting waste heat into electricity with near-perfect efficiency, and Rice University engineers have taken a big step toward that goal.

Flexible photonic crystal from liquid thin-film metasurface

Photonic crystals are predicted to be one of the wonders of the 21st century. In the 20th century, new understanding of the electronic band structure-the physics that determines when a solid conducts or insulates-revolutionized ...

Silver improves the efficiency of monograin layer solar cells

As a result of their two-year joint project, the materials researchers of Tallinn University of Technology have improved the efficiency of next generation solar cells by partial substitution of copper with silver in absorber ...

Turning up the heat to create new nanostructured metals

Scientists have developed a new approach for making metal-metal composites and porous metals with a 3-D interconnected "bicontinuous" structure in thin films at size scales ranging from tens of nanometers to microns. Metallic ...
