China hits back at U.S. tariffs by restricting export of crucial metals: tungsten, tellurium, bismuth, molybdenum and indium.

Researchers at the Pabna University of Science and Technology, in Bangladesh, have developed a new architecture for thin-film solar cells based on copper bismuth oxide (CuBi 2 O 4). CuBi 2 O 4 is ...

2). Bismuth is mainly found in the ores bismuthinite (bismuth sulfide) and bismite (bismuth oxide), but also occurs in its elemental state, in the form of crystals with an oxide layer of varying ...

It's not clear which is worse. When bismuth is left in air it reacts with oxygen to give a thin film of bismuth oxide. The oxide has light-scattering properties, which are responsible for the colors.

China announced export controls on Tuesday targeting five metals used across defence, clean energy and other industries ...

This effect occurs due to the interference of light waves reflecting off multiple layers of a material, such as the thin oxide layer on a bismuth crystal. As light waves bounce off these layers ...

The research theme was" Manufacturing technology for oxide superconductors (bismuth superconductors), which was adopted by the' Contract Developmet' system in 1990, with Sumitomo Electric Industries, ...

The results pointed toward one type of defect—in which an antimony, bismuth or iodine atom is embedded within the usual structure of calcium and oxygen that make up calcium oxide. "We never ...

The rising tensions have highlighted the importance of establishing a more resilient supply chain for critical metals. Korea ...
