From Nanotechnology to Nanoengineering
In those early days, nanotechnology referred to the possibility of synthesis via direct manipulation of atoms and molecules for fabrication of macroscale products. In the 1990, K. Eric Drexler and M. Minsky used the word “nanotechnology” in their book “Engines of Creation: The Coming Era of Nanotechnology” (Drexler and Minsky 1990), in which they proposed assembling machines and devices on the ...
متن کاملIndependent Electrons Moving in Attractive Δ - Function Potentials in One
We illustrate the main features of a recently proposed method based on ensemble density functional theory to divide rigorously a complex molecular system into its parts [M.H. Cohen and A. Wasserman, J. Phys. Chem. A 111, 2229 (2007)]. The illustrative system is an analog of the hydrogen molecule for which analytic expressions for the densities of the parts (hydrogen “atoms”) are found along wit...
متن کاملNanoengineering defect structures on graphene.
We present a new way of nanoengineering graphene by using defect domains. These regions have ring structures that depart from the usual honeycomb lattice, though each carbon atom still has three nearest neighbors. A set of stable domain structures is identified by using density functional theory, including blisters, ridges, ribbons, and metacrystals. All such structures are made solely out of c...
متن کاملPlasma Nanoengineering and Nanofabrication
With the recent advances in nanotechnology, plasma nanofabrication has become an exciting new niche because plasma-based approaches can deliver unique structures at the nanoscale that cannot be achieved by other techniques and/or in a more economical and environmentally friendly manner.[...].
متن کاملSolution-Based Nanoengineering of Materials
Solution-based synthesis is a powerful approach for creating nano-structured materials. Although there have been significant recent successes in its application to fabricating nanomaterials, the general principles that control solution synthesis are not well understood. The purpose of this LDRD project was to develop the scientific principles required to design and build unique nanostructures i...
