An original state, both solid and liquid at the same time: this is the latest news on a substance -water- so familiar to everyone but which appears to hold always fresh surprises for scientists. Its name is “superionic water”; it doesn’t exist on Earth but it could be abundant inside certain planets of the solar system such as Uranus and Neptune and on many of the exoplanets of more recent discovery.
And the goalposts are shifting. “When it comes to saying where the supremacy threshold is, it depends on how good the best classical algorithms are,” said John Preskill, a theoretical physicist at the California Institute of Technology. “As they get better, we have to move that boundary.”
Boeing Leads Investment In New High Energy Density Battery That Could Eventually Enable Electric Flight
Batteries are currently taking over ground transport with electric cars and trucks, but battery technology is improving so quickly that it is soon expected to spread to air transport soon.
“One general philosophy for making something that can maintain high stress is to make it so strong that it’s unbreakable,” said Huang, professor of materials science and engineering in Northwestern’s McCormick School of Engineering.
When they illuminated the membrane with sunlight, they found the proton conductivity increased by 10 times, according to Dr Marcelo Lozada-Hidalgo, who led the research alongside Prof Sir Andre Geim.
A solar-driven photoelectrochemical cell provides a promising approach to enable the large-scale conversion and storage of solar energy, but requires the use of Earth-abundant materials.
