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

Improving Dialysis Process with Graphene

Researchers from Mechanical and Electrical Engineering Departments of MIT recently showed that graphene is a powerful material candidate for use in the dialysis systems (such as hemodialysis machines in medical institutes for filtering human blood). In order to prepare graphene as a dialysis material, researchers used a procedure opposite to the general treatments that nanotechnology people use. Dialysis is a process of filtering different solutions such as human blood by a membrane in order to remove waste molecules, drugs, chemical residues from the solution. In some cases, the process can be used for purification of chemicals or isolation of different molecules for medical diagnosis. It is an essential process for scientists especially in the medical operations.

Graphene Tyres and Graphene Brake Pads

Could Graphene Use Create A Distruptive Technology In Tyre Sector? Almost every day, we see new applications emerging from graphene. The fact is certain; graphene is a disruptive technology that holds huge potential for commercialization. Graphene has abilities to open new markets and even replace existing materials or material technologies. A brand new application of graphene came out which is producing graphene tyres and brake pads. https://www.canadacarbon.com/brake-linings-gasket... In 2016 GraphChina (Graphene Innovation Conference); Sentury and Huagao launched their first electrostatic conducting graphene tyre on September 22nd. 2-3 weeks before the conference Sentury and Huagao officially announced their cooperation on the product. During the press conference, Sentury’s engineers (which is branded with the Landsail moniker), revealed that the latest test data shows their graphene-enhanced tyre offers; 1.8 meters shorter stopping distances (6 % improvement on conv...
