A study conducted by researchers at the University of Utah in Salt Lake City, Utah, USA, describes ways to improve tungsten ductility. It is generally accepted that pure tungsten and tungsten alloys with minor alloy additions are brittle at room temperature and have high ductile-to-brittle transition temperatures (DBTT). Improving the ductility of tungsten is important in generating the range of tungsten manufacturing and applications.

Researchers at the University of California have conducted a study on the effect of tungstate on nitrate reduction in Pyrobaculum aerophilum, a hyperthermophilic archaeon that can respire both at low levels of oxygen and anaerobically with nitrate as the electron acceptor. Under anaerobic growth conditions, nitrate is reduced to molecular nitrogen via the denitrification pathway.

Molybdenum-Based Sodium Ion Batteries Development

sodium ion batteries are coming image

A recent study carried out by Yu Jiang et al at Jiangsu Key Laboratory of Thin Films, Soochow University, Suzhou, China has investigated the Molybdenum-based materials for sodium ion batteries (SIBs). SIBs are considered to be one of the most promising candidates for energy storage required for renewable energy sources. The main difficulty is finding a suitable anode material, and molybdenum-based materials are expected to solve this problem.

Electron Flow Versus Magnetic Flux in Monolayer Molybdenum Disulfide Quantum Dot

Molybdenum disulfide quantum dots image

Researchers from Morocco have investigated the Dirac electron scattering problem in quantum dots of monolayer molybdenum disulfide (MoS2) quantum dots subject to magnetic flux. Analytical expressions for the eigenstates, scattering coefficients, scattering efficiency, and radial component of the reflected electron flow were developed by solving the Dirac equation.
