Rutile Titanium Dioxide Nanoparticles: Description, Usage, and Applications

Titanium dioxide is also called titania which occurs oxide of titanium in nature, and its resources are ilmenite, rutile, and anatase. It is a large-band gap semi-conductor. In 2014, world production exceeded nine million metric tons, and it has been valued at $13.2 billion. Since it has unique optical and chemical properties, titanium dioxide nanoparticles have been studied and numerous applications are found. They are also called ultrafine titanium dioxide. Small size add a significant property to nanoparticles of titanium oxide which makes it photocatalytic material. High chemical stability, and strong oxidizing power are also properties of titanium dioxide nanoparticles among others.

In consideration of being a rutile titanium dioxide nanoparticles as you can see the structure in the figure above, the nanoparticle one is more absorbent than larger size, and it has many synthesizing methods like Laser Ablation method. Since the band gap of rutile titanium dioxide nanoparticles is 3 eV which is lower than band gap of zinc oxide, and it has already applications in semiconductor technology as sensors. Therefore, rutile titanium dioxide nanoparticles are commonly studied in photonics, and semiconductor technology. It can be functionalized to absorb UV radiation in commercial applications. It can be additive or component of composites to insert photocatalytic activity to composites. One can also mix rutile and anatese to make band gap alignment.
A research group at Changwon National University conducted a study that they synthesized rutile titanium dioxide nanoparticles using sol-gel method followed by hydrolysis of TiCl4 at low temperature. They also found that the size is 26.4 nm at 300 C°, and the size increase with temperature. Another research group studied photocatalytic applications of room temperature rutile titanium dioxide nanoparticles, and they concluded that it shows a remarkable photocatalytic efficiency on degradation of MB Dye, RB Dye, and PNP. They examined the degradation of materials via UV-Vis spectrophotometry. As a result, degradations of MB Dye, RB Dye, and PNP are 97%, 98%, and 80% respectively.
Rutile titanium dioxide nanoparticles offer tremendous applications in many fields. There are researchers conducting experiments to develop new and cost effective synthesis methods, and many more applications will be found.

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

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.
