Exotic Metal-Insulator Transition in a Surface-Doped 2D Semiconductor

Metal-insulator transition (MIT) driven by many-body interactions is an important phenomenon in condensed matter physics. Exotic phases always emerge around the metal-insulator transition points where quantum fluctuations arise from a competition among spin, charge, orbital, and lattice degrees of freedom.

Nanoporous Material Shows Promise for Enhanced Solar Water Splitting

One prospective source of renewable energy is hydrogen gas produced from water with the aid of sunlight. Researchers at Linköping University, Sweden, have developed a material, nanoporous cubic silicon carbide, that exhibits promising properties to capture solar energy and split water for hydrogen gas production. The study has been published in the journal ACS Nano.

'Opposite Action' Strategy Shows Promise for Improving Industrial Gas Separation

A more energy-efficient method improves how an industrial gas is purified by reversing the traditional process. The concept was developed and successfully tested by scientists at Kyoto University's Institute for Integrated Cell-Material Sciences (iCeMS) in Japan and colleagues. The findings were reported in the journal Angewandte Chemie International Edition.
