Excitons are pairs of bound negatively charged electrons and positively charged holes that form in semiconductors, enabling ...

A new twist on bromine-based flow batteries could make large-scale energy storage cheaper, safer, and far longer-lasting. Bromine-based flow batteries store and release energy through a chemical ...

Scientists in the United States have created a small device that produces a tiny electrical signal from Earth’s natural rotation. Although the voltage is extremely small, the experiment shows that ...

Researchers in China have developed a zinc–bromine flow battery that runs 700 cycles with no corrosion and reduced bromine ...

A weird phenomenon in which electricity flows like water was spotted in a nanowire made of "strange metal" — a bizarre metal phase that has stumped physicists for 40 years. When you purchase through ...

July 30 (UPI) --Researchers have developed a new way to generate electricity by moving saltwater across thin films of iron oxide, or rust. The discovery, detailed this week in the journal PNAS, could ...

It's not unusual to find rust around salt water, but now the pairing might actually be useful. Researchers at Caltech and Northwestern University have found that electricity can be produced when salt ...
