Going solid-state could make batteries safer and longer-lasting

If you pry open one of today's ubiquitous high-tech devices—whether a cellphone, a laptop, or an electric car—you'll find that batteries take up most of the space inside. Indeed, the recent evolution of batteries has ...

New quantum memory stores information for hours

Storing information in a quantum memory system is a difficult challenge, as the data is usually quickly lost. At TU Wien, ultra-long storage times have now been achieved using tiny diamonds.

A new state of matter: Quantum spin liquids explained

Magnetism is one of the oldest recognised material properties. Known since antiquity, records from the 3rd century BC describe how lodestone, a naturally occurring magnetised ore of iron, was used in primitive magnetic compasses. ...

'Surgery in a pill' a potential treatment for diabetes

Over the last decade, bariatric surgeons have made strides in performing weight loss surgery that not only reverses obesity but can also reverse type 2 diabetes in patients with both conditions. Despite dramatic improvements ...

Nanosized ferroelectrics become a reality

Using ferroelectricity instead of magnetism in computer memory saves energy. If ferroelectric bits were nanosized, this would also save space. But conventional wisdom dictates that ferroelectric properties disappear when ...
