Abstract: Molybdenum heterogeneity in euxinic …
In ancient sedimentary systems, high molybdenum (Mo) enrichments are associated with strong euxinic conditions. Molybdenum isotopes (δ98Mo) have been used as a paleo-redox proxy for more than two decades. Within sulfidic waters, MoO 4 2− can undergo thiolation: Sulfur (S) replaces molecular oxygen (O) to form thiomolybdate species (MoO x S(4 ...

Surface-functionalized polydimethylsiloxane sponges for …
The present study fabricated two types of surface-functionalized polydimethylsiloxane sponges (amine-functionalized and extractant-impregnated), and investigated their applicability as a novel separation-recovery method for molybdenum ion (Mo(VI)) in aqueous and HNO 3 solutions. An amine-functionalized polydimethylsiloxane (PDMS) sponge was prepared using glycine …
Impact of Molybdenum Compounds as Anticancer Agents
The aim of this mini review was to report the molybdenum compound intervention to control cancer disease. The intervention explains its roles and progress from inorganic molybdenum compounds via organomolybdenum complexes to its nanoparticles to control oesophageal cancer and breast cancer as case s …

Abstract: Molybdenum solubility and partitioning in …
molybdenum transport and precipitation are still poorly known. To fill this gap and provide insight into the formation of Collision-type porphyry Mo deposit, we performed high pressure experiments to systematically quantify the role of CO 2 on the solubility of molybdenum-bearing phases. Molybdenite was placed together with a single-phase H 2 O ...

Alloy Design for Powder Bed Fusion
Abstract Molybdenum components manufactured using Powder Bed Fusion-Laser Beam (PBF-LB) currently cannot achieve the mechanical properties and quality of powder-metallurgically produced parts. This is a result of the process characteristics of steep thermal gradients and high solidification rates in PBF-LB, which promote the development of a ...

Character and Origin of Climax-Type Molybdenum Deposits
Abstract. Porphyry molybdenum deposits are spatially, temporally, and genetically associated with porphyritic intrusions of quartz monzonite to high silica, alkali-rich granite composition. Most molybdenum is in quartz-molybdenite veinlets that are part of an intrusion-centered stockwork of veinlets. Associated minerals are pyrite and fluorite.
