[2] [3] Three-dimensional structures can be fabricated by repeating this procedure. The cold-welding approach has the advantage of reducing surface contact contamination or defect due to no heating process, which is a main problem in the latest development and fabrication of organic electronic devices and novel solar cells.
At the nanoscale, size effects and different dimensional constraints, like grain boundaries, dislocations, and distribution of voids, can tremendously change the properties of a material. Nanolattices possess unparalleled mechanical properties. Nanolattices are the strongest existing cellular materials despite being extremely light-weight.
Nanomaterials describe, in principle, chemical substances or materials of which a single unit is sized (in at least one dimension) between 1 and 100 nm (the usual definition of nanoscale [1]). Nanomaterials research takes a materials science -based approach to nanotechnology , leveraging advances in materials metrology and synthesis which have ...
Nanotechnology is the manipulation of matter with at least one dimension sized from 1 to 100 nanometers (nm). At this scale, commonly known as the nanoscale, surface area and quantum mechanical effects become important in describing properties of matter.
Nanocomposite is a multiphase solid material where one of the phases has one, two or three dimensions of less than 100 nanometers (nm) or structures having nano-scale repeat distances between the different phases that make up the material.
InGaN/GaN nanorod array light-emitting diodes can be manufactured with dry etching or focused ion beam etching techniques. [6] Such LEDs emit polarized blue or green light [7] Three-dimensional nanorod structures have a larger emitting surface, which results in better efficiency and light emission compared to planar LEDs.

Nanofibers were first produced via electrospinning more than four centuries ago. [28] [29] Beginning with the development of the electrospinning method, English physicist William Gilbert (1544-1603) first documented the electrostatic attraction between liquids by preparing an experiment in which he observed a spherical water drop on a dry surface warp into a cone shape when it was held below ...
Nanochemistry is an emerging sub-discipline of the chemical and material sciences that deals with the development of new methods for creating nanoscale materials. [1] The term "nanochemistry" was first used by Ozin in 1992 as 'the uses of chemical synthesis to reproducibly afford nanomaterials from the atom "up", contrary to the nanoengineering and nanophysics approach that operates from the ...
