Generating cold with solids

After more than a century, physicists aim to dethrone the tried-and-tested technology of the refrigerator, as cooling can be made more energy-efficient.

Diapers can be recycled 200 times faster with light

More than 100,000 tons of diapers are disposed of annually in Germany. Vast amounts of valuable resources, such as diaper liners, end up in the trash. The liners consist of special polymers, so-called superabsorbers.

Titanium oxide material can remove toxic dyes from wastewater

Discharged in large quantities by textile, cosmetic, ink, paper and other manufacturers, dyes carry high-toxicity and can bring potential carcinogens to wastewater. It's a major concern for wastewater treatment—but researchers ...

Ionic crystal generates molecular ions upon positron irradiation

The positron, the antiparticle of the electron, has the same mass and charge as that of an electron but with the sign flipped for the charge. It is an attractive particle for scientists because the use of positrons has led ...

A simpler way to connect quantum computers

Researchers have a new way to connect quantum devices over long distances, a necessary step toward allowing the technology to play a role in future communications systems.
