Bismuth - Properties, Reactions, Atomic: Bismuth is a rather brittle metal with a somewhat pinkish, silvery metallic lustre. Bismuth is the most diamagnetic of all metals (i.e., it exhibits the greatest opposition to being magnetized). It is hard and coarsely crystalline. It undergoes a 3.3 percent expansion when it solidifies from the molten state. Its electrical conductivity …

Two-dimensional (2D) bismuth oxyhalides (BiOX) have attracted much attention as potential optoelectronic materials. To explore their application diversity, we herewith systematically investigate the tunable properties of 2D BiOX using first-principles calculations. Their electronic and optical properties can be modulated by changing the …

In such cases, bismuth quadruple therapy is the recommended first-line regimen due to its high eradication rate. Quinolone-based therapy or repeated bismuth quadruple therapy can be used as second-line therapy. However, clinical studies on rescue therapy are lacking, though susceptibility-guided therapy is suggested.
