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

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.

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

Magnesium Oxide Nanoparticles/Nanopowder and Applications

General Information about Magnesium Oxide Magnesium oxide which has the chemical formula of MgO, is a white hygroscopic solid mineral that occurs naturally as periclase and is a source of Magnesium. It is a white powder at room temperature. Magnesium Oxide has very high melting point (2825  o C) and boiling point (3600  o C).                                                                                                                                                                                Magnesium Oxide Nanoparticles/Nanopowder and Usage Areas                                        Magnesium Oxide nanoparticles/nanopowder  can be used in many different areas. For example Magnesium Oxide nanoparticles/nanopowder are used as a fire retardant for chemical fiber and plastics trades. For making crucible, smelter, insulated conduit, electrode bar, and electrode sheet  Magnesium Oxide Nanoparticles/Nanopowder  can be used as electric insulating material. Magnesium Oxide nan
