Optical absorption results revealed the WOx/CsyWO3 heterostructured composite exhibits a strong absorption tail in the Vis and NIR regions which could have important implications for its photoactivity. It can be used as photocatalyst. The photocatalytic performance of synthesized samples with different Cs/W molar ratios was evaluated by the photodegradation of RhB in aqueous solution under simulated solar light irradiation.

Tungsten alloy submarine counterweight can diminish the extent of stabilizer with its high thickness so it can add to the conveyance of weight and enhance affectability of control system. 

Tungsten alloy counterweight is a F1 specific tuning option and is now becoming the most popular material for balancing race cars. Tungsten heavy alloy is the best material to be used as counterweight which can be used in motor sport, because it has the good properties: high density with small volume, high temperature resistance, non-toxic and environmentally.

In the tungsten-copper alloy, the high melting point tungsten forms a refractory skeleton, which makes the material resistant to arcing, abrasion and high temperature, while the low melting point copper (Cu) has excellent electrical conductivity, thermal conductivity and good plasticity. Therefore, tungsten-copper alloy is widely used as an electrical contact material for high-voltage and ultra-high-voltage electrical switches.
