A photosensitizing nanosystem based on PEGylated PLGA nanoparticles doped with luminescent molybdenum-iodide nanoclusters displays advantageous features for photodynamic therapy of ovarian cancer.

The identification of the active sites in heterogeneous catalysis requires a combination of surface sensitive methods and reactivity studies. We determined the active site for hydrogen evolution, a reaction catalyzed by precious metals, on nanoparticulate molybdenum disulfide (MoS2) by atomically resolving the surface of this catalyst before measuring electrochemical activity in solution. By pr...

Ceramic hollow spheres of MoS2 and MoO3 were obtained by sonochemical synthesis of MoS2 and MoO3 templated on silica nanoparticles (diameters 50-500 nm) followed by acid etching to remove the silica core. The resulting hollow materials have been characterized by elemental analysis, XPS, SEM, TEM, optical absorption, and hydrodesulfurization (HDS) studies. The TEM studies on the hollow ceramic m...

Atomically thin molybdenum disulfide (MoS2) layers have attracted great interest due to their directgap property and potential applications in optoelectronics and energy harvesting. Meanwhile, they are extremely bendable, promising for applications in flexible electronics. However, the synthetic approach to obtain large-area MoS2 atomic thin layers is still lacking. Here we report that wafer-sc...

The present research paper deals with the oxidation process of molybdenum ore. The main target of the present study is the up-gradation of MoO3 from roasted molybdenum ore by a leaching process without waste generation. The most important application of hydrometallurgical processing is the leaching process of the ore and it is the primary process to make pure metal from ore. The present investi...

In the present study, we fabricated tungsten trioxide nanoparticles (WO3 NPs) from a complex [W(C13H10NO)3] of ligand N-salicylideneaniline with tungstic acid as precursor. Nanoparticles were synthesized using direct thermal decomposition method. These evaluated for cytotoxicity influence on human breast cancer MCF7 cell line (adenocarcinoma). The observed results suggested that WO3 can destroy...

The ability to grow high-quality, single-crystal transition metal dichalcogenides (TMDCs) is important for the application of electronic and optoelectronic devices. Here, we report epitaxial growth highly-aligned molybdenum disulfide (MoS2) on c-plane sapphire by chemical vapor deposition (CVD). base edge MoS2 flakes mainly along [11−20] crystallographic orientation sapphire. Structural charact...

Monolayer molybdenum trioxide (MoO$_3$) is an emerging two-dimensional (2D) material with high electrical conductivity. Using first-principles calculations and a Boltzmann transport theoretical framework, we predict record low room-temperature phonon thermal conductivity ($\kappa_p$) of 1.57 W/mK 1.26 along the principal in-plane directions MoO$_3$ monolayer. The behavior attributed to combinat...
