Today’s big question: What are RARE EARTHS?

Rare earths actually must be called as silent heroes of modern technology and industry. Rare earths are series of chemical elements found in the Earth’s crust that are vital to many modern technologies such as consumer electronics, computers, communications, network, clean energy, transportation, health care, environmental mitigation, national defense, military technologies, battery systems, wind turbines and many others.

World technology and energy community use these rare earths in several fields. The Japanese call rare earths “the seeds of technology.” The US Department of Energy calls rare earths “technology metals.”

Rare earth elements are 17 elements that are considered to be rare earth elements in the periodic table—15 elements in the lanthanide series and two additional elements that share similar chemical properties.

Who are these silent heroes?

Molybdenum Trioxide Nanoparticles/Nanopowder and Applications

General Information about Molybdenum Trioxide Molybdenum trioxide is chemical compound with the formula MoO3. Its chief application is as an oxidation catalyst and as a raw material for the production of molybdenum metal. Molybdenum Trioxide is a very light blue powder. Molybdenum Trioxide Nanoparticles/Nanopowder and Their Applications Like many nanoparticles/nanopowder , Molybdenum Trioxide nanoparticles/nanopowder are used as catalysts. These catalysis reactions include hydrogenation catalysis and cracking catalysis. Molybdenum Trioxide nanoparticles/ nanopowder are useful for...

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...
