Cobalt sulfate hydrate, gallium arsenide, molybdenum trioxide, vanadium pentoxide, and nickel sulfate heptahydrate were tested in the Syrian hamster embryo (SHE) assay in order to increase the SHE assay database for heavy metals. All five compounds produced significant morphological transformation at one or more doses in a dose-responsive manner. Cobalt sulfate hydrate, gallium arsenide, molybd...

Abstract TiO 2 thin films modified with MoO 3 nanostructures were obtained by the spin coating technique. The precursors solutions prepared sol-gel technique adding colloids of Mo-based laser irradiation powders suspended in liquid media. It was found that layered form colloidal solutions. characterized X-Ray Photoelectron, Raman, Ultraviolet– Visible and PL Spectroscopies, Scanning Electron Mi...

Two-dimensional and layered MoS2 is a promising candidate for next-generation electric devices due to its unique electronic, optical, and chemical properties. Chemical vapor deposition (CVD) is the most effective way to synthesize MoS2 monolayer on a target substrate. During CVD synthesis, sulfidation of MoO3 surface is a critical reaction step, which converts MoO3 to MoS2. However, initial rea...

In addition to using conventional lubricants, such as oil and grease, rolling bearings can also be used with a dry lubricant. For example, the use of lubricant systems is necessary when application oils or greases not possible (e.g., at high temperatures in aerospace applications). The requirements solid are reduce friction wear mechanical contact partners. this work, molybdenum-based coating s...

In this work, we developed a general two-step method to prepare molybdenum carbide (Mo2C) nanoparticles stabilized by a carbon layer on reduced graphene oxide (RGO) sheets. The Mo2C-RGO hybrid showed excellent performance, which is attributed to the intimate interactions between Mo2C and graphene as well as the outer protection of the carbon layer.

Gold-rhodium and gold-molybdenum layers were prepared on a nearly stoichiometric titania and characterized by LEIS, XPS and STM. In the Au-Rh bimetallic system, Rh atoms impinged onto Au clusters pregrown on TiO2(110) became covered by gold atoms. In contrast, Mo caused the disruption of gold nanoparticles.
