Highly anisotropic dry etching of tungsten silicide and tungsten polycides is required for the realization of submicron low resistance gates and interconnects for use in high performance complementary metal–oxide–semiconductor ~CMOS! and BiCMOS technologies. The current etch chemistries are not anisotropic, i.e., lateral etching of the tungsten silicide takes place which results in undesirable ...

Heavy metal-tungsten alloys (HMTAs) are dense heavy metal composite materials used primarily in military applications. HMTAs are composed of a mixture of tungsten (91-93%), nickel (3-5%) and either cobalt (2-4%) or iron (2-4%) particles. Like the heavy metal depleted uranium (DU), the use of HMTAs in military munitions could result in their internalization in humans. Limited data exist, however...

A novel electrocatalyst of layered MoS2 supported on reduced graphene oxide (RGO) decorated with nano-sized tungsten carbide (WC) shows an enhanced catalytic performance in the hydrogen evolution reaction, which could be attributed to the presence of a conductive and electrocatalytically-active nano-WC dispersant and the positive synergistic effect between nano-WC/RGO and layered MoS2.

A three dimensional (3D) hierarchical silver supported tungsten oxide flower-like microsphere catalyst has been fabricated using a cationic surfactant CTAB. It was found that the crystal-splitting mechanism plays a key role in the formation of this flower-like structure. This catalyst was proved to be highly effective in the liquid phase selective oxidation of m-xylene to isophthalic acid.

Artificial photosynthesis is a very attractive and a desirable way to solve the rising energy demand. In order to harvest energy directly from sunlight catalyst for oxygen reduction and evolution reaction are at the core of key renewable-energy technologies including fuel cells and water splitting. Herein, tungsten oxide-reduced graphene oxide (WO3-rGO), cobalt oxidereduced graphene oxide (Co3O...

OBJECTIVE To assess enamel surface under scanning electron microscopy (SEM) after resin removal and enamel polishing procedures following brackets debonding, as well as compare the time required for these procedures. METHODS A total of 180 deciduous bovine incisors were used. The enamel surface of each tooth was prepared and brackets were bonded with light cured Transbond XT composite resin. ...

A new kind of silver indium tungsten oxide (AgIn(WO(4))(2)) mesocrystals with high hierarchy can be synthesized by a microwave-assisted approach, which shows high and selective photocatalytic activity for the degradation of different organic dyes under UV and visible light irradiation.
