Fervent Hype behind Magnesium Batteries: An Open Call to Synthetic Chemists—Electrolytes and Cathodes Needed

Abstract Magnesium metal is a superior anode which has double the volumetric capacity of lithium metal and has a negative reduction potential of −2.37 V vs. the standard hydrogen electrode. A major benefit of magnesium is the apparent lack of dendrite formation during charging…

Battery-free smartphones could be available by 2018

The phone works by harvesting small amounts of power from radio signals, radio frequency (RF) waves and carrying out high-power processes at a base station. The basic proof-of-concept prototype consists of an uncovered circuit board with no screen. Headphones are attached to receive…

Harnessingthe properties of a remarkable 2-D material

Characterizing the thermal properties of crystalline molybdenum disulfide, an important two-dimensional (2-D) material, has proven challenging. Now researchers from A*STAR have developed a simple technique that could pave the way for its use in a wide range of new applications in energy storage,…

Self-supported porous WN nanowires array: an efficient 3D electrocatalyst in the hydrogen evolution reaction

J. Mater. Chem. A, 2017, Accepted ManuscriptDOI: 10.1039/C7TA04923D, Paperbowen ren, dongqi li, qiuyan jin, hao cui, Chengxin WangDevelopment of non-noble metal electrocatalysts for hydrogen evolution reaction (HER) has attracted much attention. Metal-nitrides are considered as promising alternatives in recent years. Nevertheless, the preparation…

J. Mater. Chem. A, 2017, Accepted ManuscriptDOI: 10.1039/C7TA04932C, PaperYue Liu, Bin Li, Songmei Li, Jianhua Liu, Shubin YangMetallic lithium is one of the most favorable anode materials for the next-generation energy storage systems owing to its high theoretical capacity, low density and the…

Probing the energy reactance with adiabatically driven quantum dots. (arXiv:1708.02856v1 [cond-mat.mes-hall])

The tunneling Hamiltonian describes a particle transfer from one region to the other. While there is no particle storage in the tunneling region itself, it has associated certain amount of energy. We name the corresponding flux energy reactance since, like an electrical reactance,…
