The importance of Cerium Rare Earth Element


*Cerium the second element in the Lanthanide series. This rare earth element is the most abundantly prevalent rare earth element.
*Cerium element was named for the asteroid Ceres, this rare earth metal was discovered in 1801. Cerium rare earth element is discovered in 1803 by Klaproth and by Berzelius and Hisinger.

*Cerium rare earth element is found some minerals including allanite,monazite, bastnasite, cerite, and samarskite. Today, monazite and bastnasite are more important sources of cerium rare earth element. In addition cerium metal is more abundant than Lead metal in earth’s crust.

*Cerium rare earth metal is considered to be moderately toxic. And Cerium fire produce a harmful gas if pour water on it.

*The metal tarnishes in moist air and reacts with water to form cerium hydroxide plus hydrogen gas. Small particles of the metal may ignite if a knife scratches the pure metal surface.

*When cerium-lanthanum alloy uses with a sum of neodymium and praseodymium rare earth metal
combined with Fe2O3 and MgO is used as the filint in cigarette and gas lighters. That is, it is used to include flints for cigarette lighters

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 Oxide Dispersion

Graphene oxide refers to a mono-atomic layer material obtained when graphite crystals are oxidized. This is one of the graphene materials that are commercially available because of  its ability to dissolve in water  which makes the oxidation process suitable. In this article, we will talk about the  synthesis, the properties and some of the applications of graphene oxide dispersion in water . Seven Properties of Graphene Oxide Dispersion The properties of a material are defined through its structure, however, this material is very peculiar, since there is no unambiguous model of this material. Graphene Oxide dispersion offers remarkable physical, chemical and mechanical properties that give the opportunity to new applications. Graphene Oxide is amorphous , but, in general, graphene oxide can be described as a two-dimensional sheet containing honeycomb carbon atoms with functional groups of hydroxide and oxygen, unlike the graphene model that seeks to completely re...
