The Effect of Gadolinium Powder in Our Lives

*Gadolinium powder is discovered by Jean Charles Galissard de Marignac in 1880. This powder is relatively stable in dry air. It does however oxidize in moisture forming oxides. Gadolinium is not found free in nature, therefore it is not a native metal. Gadolinium powder can be found in minerals such as xenotime and monazite.
* Gadolinium is a rare earth metal that possesses unique properties advantageous to specialized applications such as semiconductor fabrication and nuclear reactor shielding.It is very effective for absorbing neutrons, so it is very useful in nuclear reactors.Gadolinium has a very fast burnout rate and has limited use as a nuclear control rod material.
* Gadolinium powder has applications in electronics to increase the speed and capacity of computer memory. Also it is used in making Magnets, electronic components.

* Gadolinium has excellent magnetic properties. It is paramagnetic at room temperature, but becomes strongly magnetic or ferromagnetic(strongly attracted by a magnet) below room temperatures.

* Gadolinium compounds are used as green phosphors in color television picture tubes. Also, Gadolinium metal is used in alloys of iron and chromium to enhance resistance to high temperatures and oxidation.

* Compound of gadolinium powder has applications in medical magnetic resonance imaging (MRI) where it is used as intravenously administered, contrasting agents to enhance images.

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

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.

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
