Storing a Lightning Bolt in Glass for Portable Power
(PhysOrg.com) -- Materials researchers at Penn State University have reported the highest known breakdown strength for a bulk glass ever measured. Breakdown strength, along with dielectric constant, determines ...
Folding batteries increases their areal energy density by up to 14 times
Antigravity could replace dark energy as cause of Universe's expansion
Since the late 20th century, astronomers have been aware of data that suggest the universe is not only expanding, but expanding at an accelerating rate. According to the currently accepted model, this accelerated ...
Researchers develop graphene supercapacitor holding promise for portable electronics
(PhysOrg.com) -- Electrochemical capacitors (ECs), also known as supercapacitors or ultracapacitors, differ from regular capacitors that you would find in your TV or computer in that they store substantially ...
