Because of many superior physics properties such as high melting point, low sputtering rate, high thermal conductivity, low tritium inventory, high strength at elevated temperatures and low thermal expansion, tungsten-based materials are a unique choice for several applications. However, serious embrittlement in several aspects including low-temperature brittleness, recrystallization brittleness and irradiation induced brittleness is the main drawback to limit the application of tungsten-base materials, especially as the structural materials. In order to alleviate such embrittlement, some tungsten-base alloys with fine grains have been developed by previous studies.

The use of lithium ion secondary batteries (LIBs) as storage batteries for portable electronic devices and electric cars and as stationary storage batteries for solar cells and wind power generation is increasing yearly. However, their properties, such as energy density, power density, safety and durability, require further improvement to increase their use. Although graphite electrodes have been used as the negative electrode in LIBs, the durability is not long enough. Therefore, new materials for use as the negative electrode that can replace graphite have attracted interest. Transition-metal oxides are actively studied due to their good durability, high energy density and high-power density.

Since the report of electrochemical photolysis of water using TiO2 under UV illumination, it has been widely concerned on the clean energy that is generated on semiconductors driven by solar energy [1]. Simultaneously, binary metal oxide photoanodes such as ZnO, TiO2, WO3, and α-Fe2O3 had been had been widely investigated on hydrogen generation, photovoltaic device and photocatalysis. Among these materials, WO3 has been developed as a promising n-type semiconductor, since WO3 (2.7 eV) can absorb more photons than ZnO (3.2 eV) and TiO2 (3.0–3.2 eV) and possess an appropriate hole diffusion length and inherently good electronic properties. However, the sluggish kinetics of oxygen evolution reaction and rapid recombination of photon-generated carriers are the main obstacle for WO3 in terms of practical applications . Heterojunction structure, such as WO3/BiVO4 is considered as the feasible route to facilitate the charge carrier transfer of WO3.

White light-emitting diodes (LEDs) as a next generation light sources have attracted much attention due to their superior advantages over conventional incandescent and fluorescent lamps. Recently, numerous efforts have been focused to improve the color rendering index (CRI) of the white LEDs with the discovery of novel and efficient red emitting phosphor materials. Eu3+ activated luminescent materials such as sulphides, nitrides, phosphates, tungstates and molybdates were extensively investigated as red phosphors for white LEDs due to their high CRI values and low correlated color temperature over commercial YAG;Ce3+ based white LEDs.

Materials with perovskite structure are considered as perspective for Solid Oxide Fuel Cells in their standard three-layer system anode/electrolyte/cathode and the innovative construction: symmetrical or single cell. Additionally, application of ceramic proton conductive electrolyte instead of typical for SOFC oxide ion conductive (e.g. yttria-stabilized zirconia, doped ceria) allows to decrease fuel cells working temperature and prevent fuel dilution by reaction products. Thus, perovskite structure ABO3-based materials, mainly BaCeO3 and BaZrO3, seem to be the interesting group for proton conductive fuel cells.

Sulfur compounds in fuel are converted into SOx when combusted. Furthermore, SOx in automobile exhaust degrades the catalytic converter performance resulting in increased NOx emission which is another important air pollutant. In recent years, ultra-low-sulfur diesel (ULSD) was required in many countries by mandating stringent legislation to cut the S-content down to 10 ppm. At present, the traditional hydrodesulfurization (HDS), a conventional commercial technology, is wildly employed in the purification of fuels. Although HDS can remove various S-compounds such as thiols, sulfides and disulfides, when the deep desulfurization of diesel fuel is required, HDS is less effective due to the low hydrogenation activity to heterocyclic thiophenic compounds
