Carbon nanotube transistors scaled to a 40-nanometer …
Carbon nanotubes on the roadmap The formal challenge for high-performance transistors is to fit within ever smaller devices. They need to shrink from a lateral dimension of about 100 to 40 nanometers. Cao et al. fabried tiny devices by using a single semiconducting carbon nanotubes, as well as arrays of these nanotubes.

In the present study, plasma spray welding was used to prepare an in-situ niobium carbide (NbC) reinforced Ni-based composite coating on the low carbon steel, and the phase composition and the microstructure of the composite coatings were studied. The wear resistance and the wear mechanism of the composite coatings were also researched by the wear tests. The results showed that the main …

Graphite on the other hand consists of two-dimension sheets of hexagons, like a honeyco, in which each carbon atom is bonded to three others. These sheets are loosely stacked on top of each other in bulk graphite, and it is their ability to slip around on each other that makes graphite so soft and slippery.

Phase stability of nanocarbon in one dimension: …
Since their discovery in 1990, the study of sp 2 bonded carbon nanotubes has grown into a field of research in it’s own right; however the development of the sp 3 analog, diamond nanowires, has been slow. A nuer of theoretical models have been proposed to compare the relative stability of diamond and graphite at the nanoscale; and more recently, to compare nanodiamonds and fullerenes.
