Surprising discoveries about 2-D molybdenum disulfide

Scientists with the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory (Berkeley Lab) have used a unique nano-optical probe to study the effects of illumination on two-dimensional semiconductors at the ...

Insight into obscure transition uncovered by X-rays

The list of potential mechanisms that underlie an unusual metal-insulator transition has been narrowed by a team of scientists using a combination of X-ray techniques. This transition has ramifications for material design ...

Smartphones and PDA's may add to toxic substance exposure

Lifestyle factors including breastfeeding and diet may impact on expecting mothers' exposure to persistent toxic substances (PTS) including metals commonly found in electronic devices, according to a study into environmental ...

Two-dimensional material seems to disappear, but doesn't

(Phys.org)—When exposed to air, a luminescent 2D material called molybdenum telluride (MoTe2) appears to decompose within a couple days, losing its optical contrast and becoming virtually transparent. But when scientists ...
