Panorama of Climax Molybdenum Mine

open access: yes, 2022
The postcard shows the Climax Mine and buildings. The Climax Mine worked one of the largest molybdenum deposits in the world and extracted some 470 million tons of ore. Claims were staked on Bartlett Mountain, Colorado in 1879 for what was later (in 1895)

Regulating Phase Evolution and Crystallization Dynamics Enables Low Open‐Circuit Voltage Deficit in Wide‐Bandgap Cu2ZnSnS4 Solar Cells

open access: yesAdvanced Materials, EarlyView.
Bilayer composition‐modulated sulfurization (BCMS) regulates Cu redistribution in solution‐processed Cu2ZnSnS4, suppressing Cu2SnS3 and favoring the direct transformation pathway, while transforming the crystallization from surface‐dominated growth to a more synchronized process.

Mineralogical characterization of the flotation products using automated mineral liberation analysis at the Erdenetiin Ovoo Cu-Mo porphyry deposit, Mongolia

open access: yesMongolian Geoscientist
The flotation process is used to extract copper-molybdenum sulfide minerals from ore. The selection of the flotation technology scheme largely depends on factors such as the composition of sulfide ore in the ore body, grain size, and characteristics of ...

Highly Sensitive Broadband Photodetectors Based on Donor–Acceptor 2D Conjugated Coordination Polymers

open access: yesAdvanced Materials, EarlyView.
Donor–acceptor molecular design and chemical vapor deposition growth enable the two‐dimensional nickel‐tetraaminobenzoquinone films with strong broadband absorption and efficient charge separation. The resulting photodetectors exhibit a structured broadband response with a high responsivity of ∼3.1 A W−1 and a response time of ∼170 µs, which surpasses ...
