- Holmium is a chemical element with symbol Ho and atomic number 67.
- Holmium is a rare earth element.
- Holmium is a bright, soft, silvery-white, rare earth metal that is both ductile and malleable.
- Holmium does not react in dry air at normal temperatures, but rapidly oxidizes to a yellow oxide (Ho2O3) in moist air or when heated.
- Holmium has unusual magnetic properties, including the highest magnetic moment (10.6 µB) of any naturally occurring element.
- As a result of its special magnetic properties, holmium is used in alloys for the production of magnets and as a flux concentrator for high magnetic fields.
- Holmium is considered to be of low toxicity.
- Holmia (holmium oxide) is used as a yellow or red coloring for glass and cubic zirconia.
- Holmium isotopes are good neutron absorbers and are used in nuclear reactor control rods.
- Holmium is also used in solid-state lasers for non-invasive medical procedures treating cancers and kidney stones.

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 ...
