Application of Tungsten Grinders in Welding

Tungsten grinders in welding image

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.

Hydrogen-Impurity Induced Magnetism in Molybdenum Ditelluride

Comparison of soft X-ray ARPES spectra image

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.
