Titanium hosts record high superconductivity for elements superconductors

Titanium breaks record of Tc for element superconductors

21-Sep-2022

Element superconductors are important either for superconducting mechanism studies or for potential applications because of the single composition. However element superconductor (SC) usually show very low transition temperature (Tc) typically below 10K. Recently Prof. Changqing Jin’s team at ...

Graphene as 'the philosopher’s stone’: turning waste into gold

"This apparent magic is essentially a simple electrochemical process"

25-Aug-2022

Throughout history, alchemists believed in the existence of the philosopher’s stone: a substance that could turn cheap substances into precious gold. Now scientists from The University of Manchester, Tsinghua University in China and the Chinese Academy of Sciences have shown that graphene can be ...

New membrane improves reversibility of zinc-air batteries

22-Jun-2022

The long-standing challenges to the practical implementation of rechargeable zinc-air batteries (ZABs) are the electrochemical irreversibility of the Zn anode and degradation of the air cathodes in alkaline electrolyte, which eventually results in poor cycle life and low cell voltage. To improve ...

Microalgae-based conversion of carbon dioxide to biofuels

Scientists explore a genetic sensor of blue light to double oil productivity in industrial microalgae

01-Apr-2022

Microalgae, algae that cannot be seen by the naked eye, absorb carbon dioxide and produce oils that can be used as biofuels. These biofuels, which can be carbon negative, offer promise as an alternative to conventional fossil fuels. However, the biological processes that allow these microalgae to ...

Selective membrane may cycle dual-ion batteries closer to reality

Solution to a "notorious issue" provided

24-Jan-2022

Lithium-ion batteries are relatively safe, long-lasting, fast charging and better for the environment than non-rechargeable batteries–right? Not quite. The rocking-chair mechanism that allows for commercial power storage generally uses rare earth elements, such as nickel and cobalt. Researchers ...
