Nano-drilling of multiwalled carbon nanotubes (MWCNTs) has been conducted by taking advantage of CoOx as the oxidation catalyst at a relatively low temperature of 250 °C. An increase of the ID/IG ratio of Raman spectroscopy, together with TEM visualization, justifies the presence of hole ...

The stability limit between the layered-perovskite and pyrochlore structures was investigated for Ln2Ti2O7 (Ln = lanthanide) thin films grown on (110)-oriented SrTiO3 substrate by the sol–gel route. In bulk, for standard conditions of pressure and temperature, these oxides adopt the ...

We have studied the atomic layer deposition (ALD) of ruthenium using bis(2,4-dimethylpentadienyl) ruthenium and oxygen. We show that the process is achievable at a low operating temperature of 185 °C. Variation in the exposure time and pressure of the oxygen counterreactant has significant ...

We investigate the hydrogen adsorption capacity of Na-coated carbon nanotubes (Na-SWCNTs) using first-principles electronic structure calculations at absolute temperature and pressure. A single Na atom is always found to occupy the hollow site of a hexagonal carbon ring in all the six ...
