Dissecting the Re-Os molybdenite geochronometer [PDF]

Scientific Reports, 2017
Rhenium and osmium isotopes have been used for decades to date the formation of molybdenite (MoS2), a common mineral in ore deposits and the world’s main source of molybdenum and rhenium.

EFFECT of Pb2+ on the flotation of molybdenite in the presence of sulfide ion

Results in Physics, 2019
Although Na2S doesn’t depress the flotation of molybdenite, as the most utilized depressant, its effect on the flotation of molybdenite in the case where Pb2+ is involved has not been investigated yet.

Supramolecular Assembly and Interfacial Hydration of Tandem Repeat Dipeptides on 2D Nanomaterials: Insights From 3D-AFM Measurements and MD Simulations. [PDF]

Small
High‐resolution AFM visualization of nr‐YH dipeptide assemblies on graphite and MoS2 by 3D‐AFM reveals localized 3D hydration structures. These results underscore the critical role of water in stabilizing and organizing peptide assemblies on solid surfaces, thereby providing a highly potent biofunctionalization platform for biomedical and ...

The effect of sodium hydrosulfide on molybdenite flotation as a depressant of copper sulfides

Minerals Engineering, 2020
Depressing copper sulfides using sodium hydrosulfide (NaHS) in the flotation of molybdenite is a common practice. However, the effect of NaHS on the flotation of molybdenite is not clear despite a number of studies.
