Sound-powered sensors stand to save millions of batteries

Sensors that monitor infrastructure, such as bridges or buildings, or are used in medical devices, such as prostheses for the deaf, require a constant supply of power. The energy for…

Mapping local quality at super-resolution scale

Super-resolution (SR) fluorescence microscopy, through the use of fluorescent probes and specific excitation and emission procedures, surpasses the diffraction limit of resolution (200~300 nm) that was once a barrier. Most…

70kW-level high power density vanadium flow battery stack

Recently, a research team led by Prof. LI Xianfeng from the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences (CAS) developed a 70 kW-level high power density vanadium…

Self-powered sensor automatically harvests magnetic energy

A system designed at MIT could allow sensors to operate in remote settings, without batteries. MIT researchers have developed a battery-free, self-powered sensor that can harvest energy from its environment….

Africa’s chance for green electricity

Dependence on coal and gas could be overcome in Africa first – study examines requirements for a post-fossil-fuels scenario. A joint study by the University of Tübingen, the Senckenberg Society…

Smooth operation of future nuclear fusion facilities is a matter of control

The Lehigh University Plasma Control Group, supported by a new $1.6 million DOE grant, continues work on advancing plasma dynamics simulation capabilities and algorithms to control superheated gasses that hold…
