Rundown About Iridium

Properties:

Iridium, shortened as Ir with atomic number 77 is in Group 9 of the periodic table. Iridium is a transition metal that is a part of the platinum family. The metals in the platinum family are otherwise called the noble metals. They have this name since they don't respond well with different components and mixes. They give off an impression of being "excessively prevalent, making it impossible to respond with most different substances.

Iridium is the most corrosion-resistant metal known. It isn't influenced by high temperatures, acids, bases, or most other solid chemicals. That property makes it helpful in producing items that are exposed to such materials. Iridium metal is shimmering white with a density of 22.65 grams for every cubic centimeter. A cubic centimeter of iridium weighs 22.65 times as much as a cubic centimeter of water. Iridium is the densest element. Iridium has a boiling point of around 4500C and a melting point of about 2440C. Iridium metal can't be normally utilized because it breaks rather than bends. It turns out to be more adaptable when exposed to a hot temperature.

Iridium does not react at room temperatures. At the point when exposed to air, Iridium reacts with oxygen to frame a thin layer of iridium dioxide (IrO2 ).

At high temperatures, the metal turns out to be more receptive. At that point Iridium reacts with oxygen and halogens to form iridium dioxide and iridium trihalides.

Applications:

Iridium is used mainly in alloys to strengthen the material.

Iridium can be alloyed with platinum to produce and exceptionally strong material.

Iridium is used in sparkplugs of helicopters.

Iridium can be utilized to make electrical contacts, electrical wires , electrodes.

Iridium is used to make pen tips, compass bearings.

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
