Cation exchange is a conventional but promising technique for new nanorod synthesis. Cation exchange transformations in nanorods are kinetically favorable and often shape-conserving. Compared to bulk crystal systems, the cation exchange of nanorods is million-times faster due to high surface area.
A <111> surface (normal to the largest diagonal of a cube) of pure diamond has a hardness value of 167±6 GPa when scratched with a nanodiamond tip, while the nanodiamond sample itself has a value of 310 GPa when tested with a nanodiamond tip.
A zinc oxide nanorod sensor or ZnO nanorod sensor is an electronic or optical device detecting presence of certain gas or liquid molecules (e.g. humidity, [2] NO, hydrogen, [3] [4] etc.) in the ambient atmosphere. The sensor exploits enhanced surface area (and thus surface activity) intrinsic to all nano-sized materials, including ZnO nanorods.
Detonation synthesis utilizes gas-based and liquid-based coolants such as argon and water, water-based foams, and ice. [10] Because detonation synthesis results in a mix of nanodiamond particles and other graphitic carbon forms, extensive cleaning methods must be employed to rid the mixture of impurities.
Most synthesis techniques use a bottom-up approach. Initial synthesis via either method may often be followed by a nanowire thermal treatment step, often involving a form of self-limiting oxidation, to fine tune the size and aspect ratio of the structures. [7] After the bottom-up synthesis, nanowires can be integrated using pick-and-place ...
Colloidal gold is a sol or colloidal suspension of nanoparticles of gold in a fluid, usually water. [1] The colloid is coloured usually either wine red (for spherical particles less than 100 nm) or blue-purple (for larger spherical particles or nanorods). [2]

Based on their size and material composition, it is possible to tune the maximum absorption peak for nanorods during their synthesis. This control has led to the creation of photosensitizing nanorods. [25]
