Gadolinium Oxide Properties and Applications

Gadolinium oxide (Gd2O3) compound is the oxide form of one of the rare earth metal gadolinium. Gadolinium oxide is also known as gadolinium sesquioxide, gadolinium trioxide and Gadolinia. The color of the gadolinium oxide is white. Gadolinium oxide is odorless, not soluble in water, but soluble in acids. Gadolinium oxide could be appeared in three different structures: cubic (c-Gd2O3), monoclinic (m-Gd2O3) and hexagonal (h-Gd2O3). The cubic gadolinium oxide changes to monoclinic structure at 1200oC. While the hexagonal gadolinium oxide phase exists above melting point which is at temperature of 2420oC. Gadolinium oxide is the most available form of the pure gadolinium. Gadolinium oxide has physiochemical properties like the crystallographic stability up 2325oC, high mechanical strength, excellent thermal conductivity, and a wide band optical band. The gadolinium oxides has a variety of applications.
Gadolinium oxide is used in magnetic resonance and fluorescence imaging
Gadolinium oxide is used as enhancer of the scan clarity in MRI
Gadolinium oxide is used as contrast agent for MRI
Gadolinium oxide is used in fabrication of the base for Judd-Ofelt high-efficiency luminescent devices
Gadolinium oxide is used in doping-modification of thermally treated nanocomposites
Gadolinium oxide is used in semi-commercial manufacturing of magneto caloric materials
Gadolinium oxide is used for making optical glasses
Gadolinium oxide is used as burnable poison, in other words, gadolinium oxide is used as part of the fresh fuel in compact reactors to control the neutron flux and the power

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 th...

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. Figure: Single Walled Carbon Nanotube (SWCNT) It ha...
