ESTIMATED MANUFACTURING COSTS FOR THE RECOVERY OF THORIUM AND URANIUM FROM MONAZITE SAND [PDF]

, 1950
Costs are estimated for the production of uranium and pure thorium from monazite concentrates. The process involves; reaction of the monazite with caustic soda, dissolution of the hydrous oxides in hydrochloric acid, separation from the bulk of the rare earths by hydroxide precipitation of thorium and uranium, and purification by solvent extraction ...

Sub‐1 ms Optoelectronic Synapse Based on {ZnCdO/ZnO} Multilayer Structure for High‐Speed Neuromorphic Vision Systems

Advanced Functional Materials, EarlyView.
Eu‐doped {ZnCdO/ZnO} structures grown on Si are developed, showcasing dual‐functionality controlled by europium doping. While high europium concentration transforms the device into an ultrafast, self‐powered photodetector, low‐doped structures can be used as an optoelectronic synapse.

Hopping‐Mediated Zero‐Bias Photocharge Retention in Solution‐Processed Van Der Waals Heterostructures

Advanced Functional Materials, EarlyView.
Liquid–liquid interface assembly enables the fabrication of solution‐processed MoS2 and WSe2 centimeter‐scale, nanometer‐thick type‐II heterostructures on paper. Interfacial charge separation and hopping‐limited recombination produce rectification and persistent photocharge retention at zero bias.
