In recent years, tungsten rings have been a popular choice for their durable and scratch-resistant properties. However, they can also lose their luster over time. Below, we will explain how to take care of your tungsten wedding ring.

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.

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.

Recent research discusses the optical and self-cleaning properties of composite films titanium/tungsten/graphene oxide thin films. The article, published in Surface and Interface, develops a discussion of the optical properties of photocatalytic titanium dioxide - tungsten trioxide - reduced graphene oxide (TiO₂-WO₃-rGO) (TWG) and TiO₂ films and the feasibility of using these films for different applications, particularly as self-cleaning coatings (SCC).

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.

The silver paste for the front electrode of solar cells is one of the main raw materials that affect the electrical properties of solar cells. The photovoltaic front silver paste is mainly composed of three parts: conductive phase, organic term and inorganic term. 

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.

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.

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.
