Hence, many attempts to purify SWCNTs have been reported by using oxidation in nitric acid [5], burning in air [6], using steam [7], etc.
A CBRAM with a 32-kb chip has been reported by using I2C (Inter-Integrated Circuit) and SPI Serial Peripheral Interfacee) bus architecture [61].
Direct reductive amination of carbonyl compounds with variety of amines has been reported by using magnetically separable Fe@Pd/C as an efficient catalyst in aqueous reaction medium.
Various morphologies of CuS such as nanowires [16], nanodisks [17], hollow spheres [18], and flower-like structures [19] have been reported by using different preparation methods, mostly by hydrothermal method.
To date, different kinds of hierarchical branched ZnO nanostructures, including nanobridges [7], nanoflowers [2, 8], rotor-like structures [9], and nanotubes surrounded by well-ordered nanorod structures [10], have been reported by using either solution-phase or vapor-phase method.
Various applications (plasmonic absorbers, for instance) have been reported by using nanodisks[26 28] or nanopillars[29] to modify the surface profile, allowing for tight confinement of more energy inside the functional layer of a solar cell.
