Abs t rac t We have s tud ied cha rac te r i za t ion of micromechanical cleavage monolayer molybdenum disulfide (MoS2) deposited on SiO2/Si and glass substrates. Spherical gold (Au) nanoparticles were anchored on top of monolayer MoS2 film. Direct reflection spectra were measured, which infers significant improvement of total average absorption of monolayer MoS2 in Vis-NIR range of 400–800 nm ...

In this work, we propose a surface plasmon resonance (SPR) biosensor based on hybrid structure of silicon nitride (Si3N4), molybdenum trioxide (MoO3), and graphene oxide (GO) in the Kretschmann configuration. To investigate performance parameters SPR biosensor, calculate, theoretically, reflectance spectra proposed model analysed it. The investigation various i.e., sensitivity, detection accura...

Fast Reacting Nano-Composite Energetic Materials: Synthesis and Combustion Characterization Report Title Energetic composites are mixtures of solid fuel and oxidizer particles that when combined offer higher calorific output than monomolecular explosives. The composites traditionally deliver energy as diffusion limited reactions and thus their power available from reaction is much smaller than ...

Sample suspension is a valuable method to improve the mechanical, thermal, electronic, and optical properties of low-dimensional materials. In terms confined light-matter waves—the polaritons, sample can elongate wavelength polaritons with positive phase velocity. Previous work demonstrates elongation ?10% for hyperbolic phonon (HPPs) in uniaxial crystals hexagonal boron nitride (hBN). this wor...

The hydrogen reduction of molybdenum trioxide to dioxide is not yet fully understood as evident by continuous scientific interest. Especially the effect potassium content on process has been considered. We prepared several samples containing varying amounts addition molybdate (K2MoO4). In situ powder X-ray diffraction experiments were then conducted study these samples. especially focused influ...

tungsten trioxide nanoparticles with two different sizes (average particle sizes about 50 and 80 nm) were prepared by the spray pyrolysis method. photo degradation of congo red (azo dye) showed that photo catalytic property of the as-prepared wo3 nanoparticles with average size about 80 nm is higher than the sample with average size about 50 nm. photo degradation of rhodamine b (cationic triary...

The main purpose of this work consists on the preparation of single layered molybdenum oxynitride, MoNxOy. The films were deposited on steel substrates by dc reactive magnetron sputtering. The depositions were carried out from a pure Mo target varying the flow rate of reactive gases, which allowed tune the crystallographic structure between insulating oxides and metallic nitrides and consequent...

Palladium-catalyzed acetylene trimerization and the metathesis of olefins catalyzed by molybdenum and its oxides are investigated in ultrahigh vacuum and at high pressures. Benzene is formed on Pd(111) by the reaction between adsorbed acetylene and a surface C4 metallocycle. The resulting benzene evolves in temperature-programmed desorption in two distinct states. The low-temperature state is p...

Two-dimensional molybdenum disulfide (MoS2) is a promising material for ultrasensitive photodetector owing to its favourable band gap and high absorption coefficient. However, their commercial applications are limited by the lack of high quality p-n junction and large wafer scale fabrication process. A high speed Si/MoS2 p-n heterojunction photodetector with simple and CMOS compatible approach ...
