Atomically MoS2 and WS2 Thin Semiconductors for Nanophotonics

atomically thin semiconductor image

Atomically thin layers of semiconductors, such as molybdenum disulfide (MoS2) and tungsten disulfide (WS2), are promising materials for nanoscale photonic devices. These nearly two-dimensional semiconductor support so-called excitons or bound electron-hole pairs, which can be aligned vertically along the thin planes of the material.

2D Molybdenum Diselenide and Its Hybrids for Hydrogen Generation Applications

2H to 1T phase transformation of 2D MoSe2 image

Hydrogen (H2) is a green and economical alternative to conventional fossil fuels due to its zero carbon emission. 2D molybdenum diselenide (MoSe2) hosts significant applications in hydrogen generation due to its low hydrogen adsorption Gibbs free energy and good electrical conductivity. The development of efficient hydrogen evolution reaction (HER) catalysts is of great interest for economical green hydrogen production.

Tungsten grinders usually hold powerful motors and work by using grinding wheels to remove material from metal workpieces. This equipment could be used for grinding, slicing, polishing as well as welding. Since tungsten rod grinders are more robust than other types of grinders, they are also commonly used in the automotive sector.

A recent study demonstrates hydrogen-impurity induced magnetism in molybdenum ditelluride (MoTe2). Layered transition-metal dichalcogenides (TMDs) are a promising class of materials with optoelectronic, superconducting, catalytic, and topological properties. In TMDs, the polymorphic MoTe2 exhibits various electronic and magnetic properties. Its metallic 1T' phase turns into a Td phase at ≈250 K. The latter is a topological Weyl semimetal with unconventional superconductivity at low temperatures.

Synthesis and Characterization of Molybdenum Carbide Catalysts on Different Carbon Supports

Molybdenum in catalyst image

The synthesis and characterization of molybdenum carbide catalysts on different carbon supports were investigated by researchers from Henan Polytechnic University. Molybdenum carbide was prepared by carburization of ammonium molybdate on cellulose, g-C3N4, MWCNTs, and sodium lignosulfonate without using any gaseous carbon source. In addition, the formation of molybdenum carbide was investigated in depth by in situ characterization using a simultaneous thermal analyzer-quadrupole mass spectrometry system.

Nucleation and Epitaxy of Bilayer Molybdenum Disulfide on Sapphire

Step-edge nucleation of bilayer MoS2 on c-plane sapphire image

A study conducted mainly by researchers at Nanjing University reports the uniform nucleation (>99%) of bilayer molybdenum disulfide (MoS2) on c-plane sapphire. Two-dimensional transition-metal dichalcogenides (TMDs) are of interest to researchers in the field of electronics. It is believed that the combination of good electrostatic control, smaller bandgap, and higher mobility than single-layer TMDs has the potential to improve the power-delay products of transistors. However, despite the progress made in the growth of single-layer TMDs, multilayer controlled epitaxial growth remains a challenge.

Biochar-Based Molybdenum Fertilizer Enhances N Assimilation in Cabbage

The Flowering Chinese Cabbage image

Low molybdenum (Mo) bioavailability in acidic soils hinders N assimilation by vegetables, and providing available Mo in acidic soils is a challenge to reduce nitrate accumulation in vegetables. A study conducted by the Institute of Guangdong Academy of Agricultural Sciences investigated three methods of molybdenum application: biochar-based molybdenum fertilizer (Mo-biochar), seed dressing, and basal application to improve Mo bioavailability and N assimilation in cabbage (Brassica parachinensis) in acidic soils.
