The morphology, composition, and bonding character (carbon hybridization state) of continuous, ultra-thin (thickness ∼60 nm) nanocrystalline diamond (NCD) membranes are reported. NCD films were deposited on a silicon substrate that was pretreated using an optimized, two-step seeding process. The surface after each of the two steps, the as-grown NCD topside and the NCD underside (revealed by etc...
For the first time, we give a fundamental understanding of the effect of borate-modified nanodiamond on propane oxidative dehydrogenation reaction. Upon increasing the loading amount of borate on the carbon surface, the propene selectivity shows a volcanic curve. The adsorption sites of borate at different loading amounts are thoroughly considered.
Mechanical properties of the orthorhombic phase of YBa2Cu3O7-δ (Y-123) at room temperature have been investigated at different applied loads using nanoindentation technique. The study was carried out for several monodomains on the (001) planes for textured Bridgman samples with dispersed Y2BaCuO5 (Y-211) particles as pinning centers. The yield strength (σys), shear stress (τm) and toughness (KI...
Nanotechnology is a new direction in science and technology, which is intensively developed during the last decade and represents one of the most important directions in the technological developments of the leading countries in 21 century. By analogy with existing microtechnologies the nanotechnologies may be considered as the technologies operating with nanometer objects. These include new na...
Visualization techniques to help understand the structure of carbon and its allotropes have been developed and applied to atomistic simulation projects which model different carbon systems on the nanoscale. Examples from ion implantation in diamond, the diffusion of hydrocarbons in nanotubes and the creation of nanodiamond from amorphous carbon under pressure are given.
