Niobium Oxide Sputtering Targets and Applications

Niobium oxide is the inorganic compound with the formula Nb2O5. It is a colourless insoluble solid that is fairly unreactive. It is the main precursor to all materials made of niobium.
Niobium Oxide (Nb2O5) Sputtering Targets (Size:1'' ,Thickness:0.125'' , Purity: 99.5%) finds a variety of applications in modem technology in different components ranging from capacitors, to waveguides , oxygen sensors and as corrosion resistant material. Apart from this, niobium oxide films are used as high refractive index layers in optical interference filters which consist of a multilayer stack of high and low refractive index materials. Due to its high refractive index, niobium oxide is an excellent candidate for optical thin film applications. Niobium oxide sputtering targets is transparent throughout the visible range. Niobium oxide also attracts attention due to its presence as a constituent of different compound oxides such as lead, barium and lithium niobate, which are used in optical waveguides and modulators. Furthermore, it has been found that niobium oxide films exhibit interesting electrochromic behaviour similar to other transition metal oxides, such as oxides of tungsten, vanadium and iridium. Moreover, niobium oxide is insoluble in water, stable in air, relatively unreactive plus acid and base resistant.
In addition to the above-mentioned properties, corrosion resistance is a must-attend issue of metallic-coated surfaces in engineering applications. Some reports reveal the good corrosion protection ability of niobium oxide. Several deposition techniques can be used to produce niobium based coatings. Sol–gel techniques, chemical vapor deposition (CVD) and physical vapor deposition (PVD) methods have been reported. The anti-corrosion performance of coatings produced by PVD is markedly affected by deposition parameters. The development of PVD-based niobium oxide coatings with enhanced corrosion properties can be more promptly accomplished if the correlation between coatings structure and deposition parameters is known.

Multi Walled Carbon Nanotube Dispersions

Carbon nanotubes (CNTs)  have attracted enormous attention in recent years due to its unique physical, electronic, optical and potential applications in materials science and nanotechnology. The van der Waals interaction between tubes, however, makes CNTs aggregate in most organic solvents and aqueous solutions, which is the major limitation of their practical applications.Various approaches have been studied to alter the CNT surface to promote the dispersion of individual nanotubes and prevent their reaggregation. On the basis of this widely accepted viewpoint, numerous techniques such as covalent bonding, surfactant coating and polymer wrapping have been developed for surface modification or sidewall functionalization.These methods, however, are complicated, time-consuming and cause permanent damage to the CNT structure and properties of the surface, which produces residues of the dispersion agent for the final product.

Carbon Nanotube Threads

Since its discovery, carbon nanotube (CNT) has attracted many interests in different technology fields due to its extraordinary properties. Properties such as, high strength, great electrical and thermal conductivity, light weight and flexibility made CNT one of the best materials for wide range of applications. However, from its name it can be understood that CNT is a nanoscale material which is very small to be applied for the production of daily products. Researchers all around the world are working on finding methods and techniques which could produce new materials with the extraordinary properties of CNT. Image retrieved from:  https://worldindustrialreporter.com/strong-light-flexible-carbon-nanotubes-threads-with-ultrahigh-conductivity/ One of these research is focusing on the production of high strength threads that can be used in the manufacturing of fabrics, cables and ropes. An international group of scientists were able to produce a flexible conductive thread that i
