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.

Tungsten alloy green bullet has higher density than lead bullet so that it has better penetrating power for armor piercing. And numerous countries have used tungsten alloy bullet for a number of years as it has high density and good firing properties, but without using lead.

Dye-sensitized solar cells (DSSCs) have drawn wide attention because of their incomparable advantages including low cost, easy to manufacture, environmental-friendly and high theoretical photoelectric conversion efficiency (PCE). However, traditional Pt CE materials are expensive, have a limited source, and are easily corroded by the I3−/I− electrolyte.

Tungsten carbide blade is fabricated using tungsten carbide or ultrafine tungsten carbide as raw materials. Wherein, tungsten carbide has hardness (HRA) of 91 and toughness (MPa) of 1471, while ultrafine tungsten carbide has hardness (HRA) of 92 and toughness (MPa) of 2550.
