Smartherm

Carbon nanotubes are carbon based nanostructures in the form of a tube about 10,000 times thinner that a human hair. They attract interest since the discovery of their outstanding properties. These nanostructures indeed exhibit a very peculiar set of thermomechanical performances (among others); they are extremely resistant but flexible and exhibit an extremely high thermal conductivity.

Carbon Dots: A Mystic Star in the World of Nanoscience

Carbon dots (CDs) have received significant attention worldwide from the beginning of this century, and recently, it has bloomed in every branch of applied sciences. Because of their outstanding physical and chemical properties together with biocompatibilities, CDs find a wide spectrum of applications in drug delivery, explosive detection, chemical sensing, food safety, bioimaging, energy

Nanostructure

When the size of a nanostructure becomes small enough (typically, smaller than the free charge carrier mean-free path in conductors, or exciton Bohr radius in excitonic semiconductors), its electronic structure (and thus its dielectric function) can depart from that of the corresponding bulk material and depend on the nanostructure size.

Carbon black manufacturing

Carbon black is produced by combusting oil or gas with a great deal of oxygen inside large furnaces. The furnace walls lined with bricks become very hot because the oxygen and oil combust. By varying the amount of oil and air, the internal temperature of the furnace can be altered, which permits manipulation of the particle size and particle connections of the carbon black

Low temperature–controlled synthesis of hierarchical

For samples prepared in 1 M NaOH alkali bath, no significant oxidation of Cu 2 O was noticed, whereas in 5 M NaOH alkali bath concentration, complete oxidation of Cu 2 O → CuO took place. However, oxidation carried out in alkali bath having 3 M NaOH leads to partial oxidation of the cuprous oxide, resulting in the development of mixed valent copper oxide–hydroxide forming CuO:Cu(OH) 2 /Cu
