Preparation of ultra-fine molybdenum‒copper composite powders and fine-grained molybdenum‒copper alloys

open access: yesFenmo yejin jishu, 2021
Ultra-fine Mo–Cu composite powders with the different Cu contents (5%, 20%, 40%, mass fraction) were prepared by the method of "carbothermic pre-reduction by insufficient carbon and deep deoxidation by hydrogen".

Influence of Adding Molybdenum on Structure and Performance of FexOy/SBA‐15 Catalysts in Selective Oxidation of Propene [PDF]

open access: yes, 2019
Mixed iron and molybdenum oxide catalysts supported on nanostructured silica, SBA‐15, were synthesized with various Mo/Fe atomic ratios ranging from 0.07/1.0 to 0.57/1.0. Structural characterization of as‐prepared MoxOy_FexOy/SBA‐15 samples was performed

Indoor residual spray bio-efficacy and residual activity of a clothianidin-based formulation (SumiShield® 50WG) provides long persistence on various wall surfaces for malaria control in the Democratic Republic of the Congo

open access: yesMalaria Journal, 2019
Background Bio-efficacy and residual activity of SumiShield® 50WG (50%, w/w) with active ingredient clothianidin, a neonicotinoid compound, was assessed using an insecticide-susceptible laboratory strain of Anopheles arabiensis.

Molybdenum Intake Influences Molybdenum Kinetics in Men [PDF]

open access: yesThe Journal of Nutrition, 2007
The objectives of this study were to determine physiologic adaptations that occur when humans are exposed to a wide range of molybdenum intake levels and to identify the pathways that are influenced by dietary intake. Four males consumed each of 5 daily molybdenum intakes of 22, 72, 121, 467, and 1490 microg/d (0.23, 0.75, 1.3, 4.9, and 15.5 micromol/d)

Atomically Dispersed Molybdenum Catalysts for Efficient Ambient Nitrogen Fixation.

open access: yesAngewandte Chemie, 2019
NH3 synthesis by the electrocatalytic N2 reduction reaction (NRR) under ambient conditions is an appealing alternative to the currently employed industrial method-the Haber-Bosch process-that requires high temperature and pressure.

Vapour phase growth and grain boundary structure of molybdenum disulphide atomic layers. [PDF]

open access: yesNature Materials, 2013
Single-layered molybdenum disulphide with a direct bandgap is a promising two-dimensional material that goes beyond graphene for the next generation of nanoelectronics. Here, we report the controlled vapour phase synthesis of molybdenum disulphide atomic

Influence of oxygen pressure on the fs laserinduced oxidation of molybdenum thin films [PDF]

open access: yes, 2018
We present a study of femtosecond (1028 nm, 230 fs, 54.7 MHz) laser processing on molybdenum (Mo) thin films. Irradiations were done under ambient air as well as pure oxygen (O2) at various gauge pressures (4, 8, 12 and 16 psi). Our results indicate that

School-based malaria prevalence: informative systematic surveillance measure to assess epidemiological impact of malaria control interventions in the Democratic Republic of the Congo

open access: yesMalaria Journal, 2018
Background In southern Democratic Republic of the Congo, malaria transmission is stable with seasonal fluctuations. Different measurements can be used to monitor disease burden and estimate the performance of control programmes.
