- Europium, a member of the lanthanides group of elements
- Europium can be easily molded or shaped and is about as hard as lead.
- Europium is the most reactive of the rare earth metals, quickly oxidizing in air and, like calcium, it reacts quickly and vigorously with water.
- Europium can be found in the ores bastnasite and monazite. The element has also been identified in the sun and some stars.
- Europium is considered to be mildly toxic. The metal dust is considered to be a fire and explosion hazard.
- Europium is the most reactive of the rare earth metals and ignites in air at temperatures in excess of 150° C to 180° C.
- Unlike most other rare earth metals, europium can form stable compounds in the divalent state, Eu2+ (europous) as well as the usual trivalent state, Eu3+ (europic).
- Europium is also used in phosphors in anti-forgery marks on Euro bank notes.
- A soft, silvery metal that tarnishes quickly and reacts with water.
- Main mining areas are China and USA. Reserves of europium are estimated to be around 150.000 tonnes and world production of the pure metal is around 100 tonnes a year
- Europium is used in the printing of euro banknotes. It glows red under UV light, and forgeries can be detected by the lack of this red glow.
- Low-energy light bulbs contain a little europium to give a more natural light, by balancing the blue (cold) light with a little red (warm) light.
- Europium is excellent at absorbing neutrons, making it valuable in control rods for nuclear reactors.
- Europium-doped plastic has been used as a laser material. It is also used in making thin super-conducting alloys.
- Europium has no known biological role. It has low toxicity.
- Europium is one of the least abundant elements in the universe; only about 5×10⁻⁸% of all matter in the universe is europium.
- Europium is a dopant in some types of glass in lasers and other optoelectronic devices.
- Europium oxide (Eu2O3) is widely used as a red phosphor in television sets and fluorescent lamps, and as an activator for yttrium-based phosphors.
- Europium is also used in the manufacture of fluorescent glass.
- A recent (2015) application of europium is in quantum memory chips which can reliably store information for days at a time; these could allow sensitive quantum data to be stored to a hard disk-like device and shipped around the countryhttps://nanografi.com/blog/not-euro-this-is-europium/

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
