Superconductivity Found In Titanium Oxide
October 5, 2017 | 6 Comments
Researchers at Tokyo Tech have reported superconductivity in two kinds of higher titanium oxides prepared in the form of ultrathin films. With a thickness of around 120 nanometers, these materials reveal properties that are only just beginning to be explored. Many of us are familiar with titanium dioxide (TiO2), a whitener commonly used in sunscreens […]

A Little Asphalt Makes a Better Lithium Ion Battery
October 4, 2017 | 3 Comments
Rice University scientists have found a touch of asphalt may be the secret to high-capacity lithium batteries that charge up to 20 times faster than commercial lithium-ion batteries. Chemist James Tour’s lab at Rice University developed anodes comprising porous carbon made from asphalt that showed exceptional stability after more than 500 charge-discharge cycles. A high-current […]

New Records For Perovskite Solar Cells
October 3, 2017 | 2 Comments
Scientists have greatly improved the operational stability of perovskite solar cells. The devices lost less than 5 percent performance when subjected to a crucial accelerated aging test during which they were exposed for more than 1,000 hours to full sunlight at 60° C. The Ecole Polytechnique Fédérale de Lausanne (EPFL) team introduced cuprous thiocyanate protected […]
