Graphene Battery

Batteries have become an important part in our electricity dependent modern lives. Every electronic device ranging from cell phones to computers rely on batteries for electricity storage. Even automobiles sector is shifting toward electric vehicles as the oil depletion and the environmental issues increase. The need for better battery with higher capacity, more stability and faster charging rates is in continuous demand. The solution is definitely in the development of new materials that have excellent properties which can increase the performance of the batteries. Graphene represent one of the best materials with extraordinary properties for the development of the batteries.

Graphene has very high surface area, hundred times better conductivity than copper and show good flexibility properties. Making battery out of graphene is one of the choices that battery developments have been working on. So far, hundreds of researches have been done that show the increase of the capacity, stability and charging rates of the graphene embedded batteries. Commercially, a Chinese company named Gongxu optoelectronics announced the first graphene battery with 4,800 mAh capacity and can be recharged in 13-15 minutes. Another company from Spain called Graphenano claims that they will produce graphene polymer cells that have 1,000 watt-hours per kilogram which is five times that of current lithium-ion cells. These developments show the importance of implanting nanomaterials such as graphene in different applications which can lead to excellent improvements in our daily lives.

Boron Carbide Nanoparticles and Their Applications

Boron carbide  which has the chemical formula of B 4 C is one of the hardest materials among the ceramics materials after diamond and boron nitride. In addition to its hardness, it has high thermal stability, low density, chemical inertness and neutron capture property. At temperature above 1200  o C, its hardness exceeds that of the diamond. Thus, it is a crucial material for high technology applications such as abrasive for polishing and grinding media, ceramic amour applications for personal purpose and equipment, blasting nozzles, ceramic bearings, semiconductor applications for dielectric barriers, medical and nuclear applications. B4C (Boron Carbide) Nanoparticles (99.5+%, 40-60nm, Hexagonal)  show an outstanding hardness among the ceramic materials. Therefore, boron carbide nanoparticles are a suitable material for many high performance applications. Boron carbide nanoparticles can be used as polishing, lapping and grinding material for hard mater...

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 ...
