These data represent some 32% of worldwide copper refineries and indicate that electrolytic refining of copper has the potential to supply ~777 t/yr tellurium, ~4,180 t/yr selenium, ~1,497 t/yr antimony, and 1,632 t/yr bismuth if recovery of the by-product critical element proxies outlined in this study could be achieved.

While it turns out that the thin films of bismuth-antimony can have some properties similar to those of graphene, changing the conditions also allows a variety of other properties to be realized. That opens up the possibility of designing electronic devices made of the same material with varying properties, deposited one layer atop another ...

Despite their potential application in many different areas, not only photovoltaics, the group of copper-bismuth sulfides has been scarcely explored. This is quite surprising, considering that all the elements are abundant and non-toxic and that analogous materials like CuInS 2, the copper-antimony family, and the copper-tin family …

Recently, halide double perovskites (HDPs), such as Cs2AgBiBr6, have been reported as promising nontoxic alternatives to lead halide perovskites. However, it remains unclear whether the charge-transport properties of these materials are as favorable as for lead-based perovskites. In this work, we study the mobilities of charges in Cs2AgBiBr6 and in …

Herein, antimony (III) (Sb 3+) is introduced into the octahedral lattice sites of the CABI structure, leading to CABI-Sb with larger crystalline domains than CABI. The alloying of Sb 3+ with bismuth (III) (Bi 3+ ) induces changes in the local structural symmetry that dramatically increase the formation energy of intrinsic defects.

Although bismuth/antimony-based chalcohalides have many advantages such as low effective mass and high dielectric constants, they generally present high bandgap, >1.7 eV (with many having bandgaps above 2.0 eV), which is challenging for efficient light absorption. Additionally, the indirect nature of the ternary chalcohalide …

Herein, we introduce antimony (III) (Sb3+) into the octahedral lattice sites of CABI structure, leading to CABI-Sb with substantially larger crystalline domains than CABI. The alloying of Sb3+ with bismuth (III) (Bi3+) induces changes in the local structural symmetry, in turn causing a remarkably increased formation energy of intrinsic defects.

Metal-based anodes have recently aroused much attention in sodium ion batteries (SIBs) owing to their high theoretical capacities and low sodiation potentials. However, their progresses are prevented by the inferior cycling performance caused by severe volumetric change and pulverization during the (de)sodiation process. To address …
