- Ytterbium is a chemical element with chemical Yb and atomic number 70 with an atomic weight of 173.05.
- Ytterbium was discovered by Jean Charles Galissard de Marignac, a Swedish chemist, in 1878.
- Ytterbium is a rare earth element.
- Ytterbium has a bright silvery luster, is soft, malleable, and quite ductile.
- Ytterbium is the fourteenth and penultimate element in the lanthanide series.
- Because of its closed-shell electron configuration, its density and melting and boiling points differ from those of the other lanthanides.
- Melting point and boiling point of Ytterbium element are 824°C and 1196°C respectively.
-Ytterbium is a soft, silvery metal.
- Ytterbium slowly oxidises in air, forming a protective surface layer.
- Density of Ytterbium is 6.90 (g cm−3).
- Ytterbium dissolves rapidly in mineral acids.
- Ytterbium is beginning to find a variety of uses, such as in memory devices and tuneable lasers.
- Ytterbium can be alloyed with stainless steel to improve some of its mechanical properties and used as a doping agent in fiber optic cable where it can be used as an amplifier.
- Under very high physical stress Ytterbium’s electrical resistance increases by an order of magnitude. Ytterbium is therefore used in stress gauges to monitor ground deformations caused by earthquakes or underground explosions.
- Ytterbium can also be used as an industrial catalyst and is increasingly being used to replace other catalysts considered to be too toxic and polluting.
- Ytterbium has no known biological role. It has low toxicity.
- One of ytterbium's isotopes is being considered as a radiation source for portable X-ray machines.
- Ytterbium compounds are capable of absorbing light in the near infra red part of the electromagnetic spectrum, which has been exploited to convert radiant energy into electrical energy in devices coupled to solar cells.
- Ytterbium, definitely an interesting and fascinating element with many uses as diverse as atomic clocks and solar cells and definitely different from the other lanthanides.

Cadmium Sulfide Nanopowder and Its Applications

Cadmium sulfide is the inorganic compound with the formula CdS. Cadmium sulfide is a yellow solid. It occurs in nature with two different crystal structures as the rare minerals greenockite and hawleyite. As a compound that is easy to isolate and purify, cadmium sulfide the principal source of cadmium for all commercial applications. Its vivid yellow color led to its adoption as a pigment for the yellow paint "cadmium yellow" in the 18th century. Cadmium Sulfide Nano Powder, CdS (99.9+%, 20 nm)  shows unique physical, chemical and structural properties from the bulk. The melting point, electronic absorption spectra, band gap energy crystal structure, and other properties of cadmium sulfide nanoparticles are affected by size. Thus, cadmium sulfide on the whole is an attractive system for practicing synthetic chemistry for nanocrystals and for understanding the chemistry, growth history of nanomaterials and also for various technical applications. Colloidal dispersions of ...

Carbon Nanotubes Doped with Graphene Nanopowder and Applications

Carbon nanotubes and graphene are different forms of carbon atom based materials. They have different properties and can be used in various applications. But what happens if we use them as a hybrid structure? The excellent mechanical, physical, and chemical properties of low-dimensional carbon materials like graphene and carbon nanotube have enabled them as promising building blocks for three-dimensional nanoarchitectures. In this regard, extensive interests have been attracted to synthesize graphene and carbon nanotube hybrid structures. Earlier works suggested that  Carbon Nanotubes Doped with Graphene Nanopowder (52 wt% Graphene )  is a promising solution for quick energy dissipation, which could enhance interface thermal conductivity of the ‘building blocks’ for future nanoscale mechanical and electrical devices. In the electricity perspective, it is found that ‘CNT pillared-graphene’ system would extend the excellent electrical conductivity of graphene and nanotube to ...
