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.

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.

Recently, researchers have proposed an analytical band calculation (ABC) model to study the band structure of monolayer molybdenum disulfide. For two-dimensional (2D) materials, a semiconductor layer is about the thickness of an atomic layer. 2D materials are gaining attention for their potential applications in future transistor manufacturing processes. 2020 International Roadmap for Devices and Systems (IRDS) predicts that by 2028, 2D materials will be the optimal choice for channel material technologies and CMOS 2D device applications.

As one of the recent hot topics, cobalt-free batteries can simply be considered as an upgraded version of the current commercial ternary lithium batteries. Because of their higher energy density and lower production costs, they are popular among many battery manufacturers. So, as a typical transition metal N-type semiconductor material, how is tungsten trioxide used in cobalt-free lithium ion battery?

Researchers at the Shanghai Institute of Microsystems and Information Technology (SIMIT), Chinese Academy of Sciences (CAS) have demonstrated that doping tungsten oxide (WO₃) catalysts with appropriate cations can change the interfacial structure, surface chemical state, and bandgap values, thus improving the performance of the basic hydrogen electrolyte reaction (HER). In the experiments, cation (Ni, Co, and Fe) doped WO₃ catalysts were synthesized on nickel foam. The Co-doped catalysts (Co WO) exhibited remarkable HER activity.

Tungsten oxide-based nanomaterials have attracted a lot of attention for their use in building various electrochemical energy devices. In particular, electrochromic devices and optical change devices have been intensively investigated in terms of energy conservation.

Considerable interest in tungsten oxide polymorphs (WO_3-x) nanomaterials has been generated due to their abundance in nature, easy availability, high stability, non-recombination, and chemical diversity, and many advances have been made from traditional catalysts and electronics to emerging artificial intelligence. A recent study from Qingdao University presents the latest progress of WO_3-x polycrystals and their multifunctional applications.
