Researchers have long sought electrically conductive materials for economical energy-storage devices. Two-dimensional (2D) ceramics called MXenes are contenders. Unlike most 2D ceramics, MXenes have inherently good conductivity because they are molecular sheets made from the carbides ...

Barely wider than a strand of human DNA, magnetic nanoparticles—such as those made from iron and platinum atoms—are promising materials for next-generation recording and storage devices like hard drives. Building these devices from nanoparticles should increase storage capaci...

Deep stores of carbon in northern peatlands may remain stable despite rising temperatures, according to a team of researchers from several U.S.-based institutions. And that is good news for now, the researchers said. Florida State University ...

Catalysts make chemical reactions more likely to occur. In most cases, a catalyst that’s good at driving chemical reactions in one direction is bad at driving reactions in the opposite direction. However, a research team led by the Department of Energy’s Oak Ridge National Laboratory ...

Atomic charges in chemical solutions are like Switzerland—they strive for neutrality. The tendency to balance charges drives dynamics when charged atoms or molecules, called ions, are present in solutions. Recently, researchers at the Department of Energy’s Oak Ridge National Laborat...

Rare earth elements are metals used in technologies from wind turbines and magnetic resonance imaging agents to industrial catalysts and high-definition televisions. Most are lanthanides, elements with atomic number from 57 to 71, lanthanum to lutetium, in the periodic table. The la...
