Sleep and aging: Two sides of one coin?

Oxford University researchers have discovered a brain process common to sleep and ageing in research that could pave the way for new treatments for insomnia.

Pushing lithium ion batteries to the next performance level

Conventional lithium ion batteries, such as those widely used in smartphones and notebooks, have reached performance limits. Materials chemist Freddy Kleitz from the Faculty of Chemistry of the University of Vienna and international ...

Pressure helps to make better Li-ion batteries

Lithium titanium oxide (Li4Ti5O12, LTO), a "zero-strain" anode material for Li-ion batteries (LIBs), exhibits excellent cycling performance. However, it shows poor conductivity, which is the major drawback and limits its ...

Very heavy elements deliver more electrons

Actinides, a series of 15 radioactive elements, are vital to medicine, energy, and national defense. Scientists examined two exceedingly rare actinides, berkelium and californium. These elements are at the extreme end of ...

Simulations reveal role of calcium in titanium implant acceptance

Titanium-based materials are widely used in medical implant technology. Coating the surface of titanium materials with biologically active molecules has recently shown promise to improve how cells adhere to implants and promote ...

A step closer to sustainable energy from seawater

The research group led by Leiden chemist Marc Koper has discovered a catalyst that minimizes the production of chlorine gas during salt water electrolysis. The invention can enable the direct production of hydrogen from seawater. ...
