Creating electricity with caged atoms

Clathrates are crystals consisting of tiny cages in which single atoms can be enclosed. These atoms significantly alter the material properties of the crystal. By trapping cerium atoms in a clathrate, scientists at the Vienna ...

Researchers turn asphaltene into graphene for composites

Asphaltenes, a byproduct of crude oil production, are a waste material with potential. Rice University scientists are determined to find it by converting the carbon-rich resource into useful graphene.

Microwave ovens a key to energy production from wasted heat

More than 60 percent of the energy produced by cars, machines, and industry around the world is lost as waste heat – an age-old problem - but researchers have found a new way to make "thermoelectric" materials for use ...

New track for converting waste heat to electricity

Huge amounts of energy are lost every day in the form of waste heat. Now an interdisciplinary project at Chalmers has found that a special class of material – high-entropy alloys – can open the door to efficient heat ...

China to end all waste imports on Jan 1

China will ban all waste imports from January 1, 2021, state media reported Friday, marking the culmination of a three-year phase-out of accepting overseas junk.

Supercomputers without waste heat

Generally speaking, magnetism and the lossless flow of electrical current ("superconductivity") are competing phenomena that cannot coexist in the same sample. However, for building supercomputers, synergetically combining ...
