We formed p-i-n heterojunctions based on a thin film of BiFeO3 nanoparticles. The perovskite acting as an intrinsic semiconductor was sandwiched between a p-type and an n-type oxide semiconductor as hole- and electron-collecting layer, respectively, making the heterojunction act as an all-inorganic oxide p-i-n device. We have characterized the perovskite and carrier collecting materials, such a...

High-quality large-area few-layer 1T' MoTe2 films with high homogeneity are synthesized by the controlled tellurization of MoO3 film. The Mo precursor plays a key role in determining the quality and morphology of the 1T' MoTe2 . Furthermore, the amount of Te strongly influences the phase of the MoTe2 . The growth method paves the way toward the scalable production of 1T' MoTe2 -based applications.

The production of lung adenomas in strain A mice following multiple i.p. injections of 13 metallic compounds was investigated. A significant increase in the average number of lung tumors per mouse was noted following the administration of lead subacetate, manganous sulfate, molybdenum trioxide, and nickelous acetate. These four compounds can be considered as weakly carcinogenic for lung tumors ...

H2MoO4 and H2WO4 upon direct laser desorption produce small clusters in the gas phase, extending up to 4500 and 7200 Da, respectively. The clustering patterns are quite similar for the two systems. The mass difference between successive peaks differ with increasing mass number as different kinds of structures become possible. A distinct planar to three-dimensional structural cross over is obser...

background; in recent years, nanoparticles have been increasingly used in industries. however, there is a serious lack of information concerning their impact on human health and the environment. this study was investigated the effect of moo3 nps on thyroid hormones in female rats. methods; in this study, 21 female wistar rats were selected and divided into three groups of untreated control, sha...

Molybdenum trioxide shows many attractive properties, such as a wide electronic band gap and high relative permittivity. Monolayers of this material are particularly important, they offer new avenues in optoelectronic devices, e.g., to alter the properties graphene electrodes. Nanoscale electrical characterization is essential for potential applications monolayer molybdenum trioxide. We present...

Catalysis is one of the core technologies in modern chemistry, energy industry and recently with promising application in biorefinery for sustainable fuels and energy production. Reducing the cost of catalyst systems is one of the ways in which technology can be brought closer to full commercialisation. The replacement of noble metals by cheaper non-precious alternatives would bring valuable sa...

We report the largest-size thin films of uniform single-layer MoS2 on sapphire substrates grown by chemical vapor deposition based on the reaction of gaseous MoO3 and S evaporated from solid sources. The as-grown thin films of single-layer MoS2 were continuous and uniform in thickness for more than 4 cm without the existence of triangular-shaped MoS2 clusters. Compared to mechanically exfoliate...
