Lanthanum: It's Applications and Uses

Humankind has been performing the use of metals in a diverse area and applications. Earlier times, humanity used these metals for producing hunting weapons and defending oneself. Nowadays applications extend their use in industrial area, multiple robotic equipment, defense ammo, etc. Therefore, we encounter use of lanthanum in many areas.
Lanthanum is one of the rare earth elements. It is a soft, ductile, silvery-white metallic chemical element with symbol La and atomic number 57. Lanthanum was first found by the Swedish chemist Carl Gustav Mosander. When we examine benefits of lanthanum, we encounter interesting area.

* Lanthanum element does not have commercial uses, but its alloys are so popular. Lanthanum is used in large quantities in nickel metal hydride rechargeable batteries for hybrid automobiles. Today, a Toyota Prius hybrid car on the road carries with it about 4.5 kg of lanthanum. These cars have nickel-lanthanum hydride batteries. Also, these batteries are about twice as efficient as the standard lead-acid car battery.

* The best-known use for mischmetal alloy of Lanthanum is; as a ‘flints’ for cigarette lighters.

* Lanthanum has application in glass and ceramic manufacturing. It is used in making special optical glasses, such as infrared absorbing glass. Because of its high refractive index and low dispersion indices Lanthanum is used as doping agents in camera and telescope lenses.

* Lanthanum is also used in alloys such as high strength alloy steels

* In catalysis Lanthanum is used in petroleum cracking and has also catalytic applications in chemical industry.

*Lanthanum is used in some pool products to reduce the level of phosphate nutrients that feed algae.

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).
