Article Abstract
The identification, fine-tuning, and process optimization of appropriate hole transporting layers (HTLs) for organic solar cells is indispensable for the production of efficient and sustainable functional devices. In this study, the optimization of a solution-processed molybdenum oxide (MoOx) layer fabricated from a combustion precursor is carried out via the introduction of zirconium and tin additives. The evaluation of the output characteristics of both organic photovoltaic (OPV) and organic light emitting diode (OLED) devices demonstrates the beneficial influence upon the addition of the Zr and Sn ions compared to the generic MoOx precursor. A dopant effect in which the heteroatoms and the molybdenum oxide form a chemical identity with fundamentally different structural properties could not be observed, as the additives do not affect the molybdenum oxide composition or electronic band structure. An improved surface roughness due to a reduced crystallinity was found to be a key parameter leading to the superior performance of the devices employing modified HTLs.

Deterministic spatial control of material properties is essential for advanced electronic and optoelectronic device technologies. van der Waals (vdW) materials stand out for their high tunability, yet achieving multifunctional on-chip control remains challenging. Here, we focus on α-MoO and site-selectively modulate both its optical emission and conductivity via electron-beam irradiation.

To address the high flammability and toxic smoke emission of flexible PVC (fPVC), a magnesium-molybdenum-phosphorus multi-component flame retardant (MO@MH-PEPE) was constructed by surface-modifying self-synthesized molybdenum oxide-hybridized magnesium hydroxide (MO@MH) with phenolic epoxy phosphate ester (PEPE). Fourier-transform infrared spectroscopy (FTIR), X-ray photoelectron spectroscopy (XPS), and scanning electron microscopy (SEM) confirmed the chemical grafting of PEPE onto MO@MH P-O-Mg bonds, enhancing interfacial compatibility. When incorporated into fPVC, the fPVC/MO@MH-PEPE composite exhibited superior flame retardancy and smoke suppression: limiting oxygen index (LOI) increased to 32.

The aim of this study is to develop nanocomposites consisting of near-infrared nanoparticle-functionalized metal-organic frameworks and investigate their antitumor performances. Using molybdenum disulfide and 30% HO as reactants, novel near-infrared molybdenum oxide nanoparticles (HxMoO NPs) were synthesized via supercritical fluid technology. A one-pot method was then employed to synthesize doxorubicin-loaded metal-organic framework nanocomposites and molybdenum oxide nanoparticles (DOX/HxMoO@ZIF-8 NPs).

Oxygen deficient molybdenum oxide nanosheet (Od-MO Nshs) was synthesised by hydrothermal method and its peroxidase-like activity was established with 3,3',5,5'-Tetramethylbenzidine-(TMB) and o-phenylenediamine dihydrochloride-(OPD) as a co-substrate in presence of Hydrogen peroxide (HO) and catalytic parameters were compared with horseradish peroxidase-(HRP) enzyme. Optimization was carried out for physical and chemical parameters. Synthesised nanoparticles-(NPs) were characterized for size, shape, composition oxidation state etc.

Electrocatalytic nitrogen reduction (NRR) offers a sustainable pathway for ammonia (NH) production but is challenged by the low solubility of N in aqueous electrolytes, the high energy barrier of N activation, and the competing hydrogen evolution reaction (HER). Herein, cucurbit[6]uril (CB[6]) is immobilized onto the surface of molybdenum oxide (CB[6]@MoO). The CB[6]@MoO catalyst exhibits a high NH production rate of 27.
