Predicting and controlling dioxins

Dioxins are a group of toxic and persistent environmental pollutants. These compounds are formed through a variety of processes but commonly through incomplete combustion of organic matter. Levels are usually monitored in ...

Tiny nanoparticles improve charge transport

Three-dimensional topological insulators are materials that can conduct electric current without resistance—but only on their surface. However, this effect is difficult to measure. This is because these materials usually ...

Researchers report an insulator made of two conductors

Ohm's law is well-known from physics class. It states that the resistance of a conductor and the voltage applied to it determine how much current will flow through the conductor. The electrons in the material—the negatively ...

New data gained on double perovskite oxides

The Journal of Alloys and Compounds has published an article coauthored by the Institute of Solid State Chemistry and Mechanochemistry (the Ural Branch of the Russian Academy of Sciences), the Donostia International Physics ...

New opportunities for light-powered battery and fuel cell design

Automotive and other industries are hard at work improving the performance of rechargeable batteries and fuel cells. Now, researchers from Japan have made a discovery that will enable new possibilities for future environmental ...

New way to investigate the electric double layer effect

Progress in lithium-ion (Li-ion) batteries have made all sorts of portable devices feasible and fueled the growth of electronics. However, the intrinsic disadvantages of conventional Li-ion batteries, whose cells use a liquid ...

Volcanoes acted as a safety valve for Earth's long-term climate

Scientists at the University of Southampton have discovered that extensive chains of volcanoes have been responsible for both emitting and then removing atmospheric carbon dioxide (CO2) over geological time. This stabilized ...
