The intermittent supply of green electricity requires large-scale storage to keep our power grids stable. Since normal batteries do not scale very well, the idea of using flow batteries, which store ...

A new flow battery design achieves long life and capacity for grid energy storage from renewable fuels. A common food and medicine additive has shown it can boost the capacity and longevity of a ...

This file type includes high resolution graphics and schematics when applicable. A most critical device in an optical networking system is the laser diode, since it’s responsible for converting the ...

Low-power circuit design has evolved into a critical research domain that addresses the dual challenges of energy efficiency and variation resilience. This field focuses on creating systems that ...

A basic rule in our lives is that if energy can flow in one direction, then it can also flow in the reverse direction. For example, if you open a window and yell at someone outside, you also can hear ...

An RC circuit in series with the coil allows full-current turn-on for reliable relay operation, then reduces the current to save power. Fellow engineer Sanjay R. Chendvankar of Mumbai, India, recently ...
