Scanning probe techniques scanning tunneling microscopy (STM) and atomic force microscopy (AFM) have emerged as unique local probes for imaging, manipulation, and modification of surfaces at the nanoscale. Exercising the fabrication of atomic and nansocale devices with desired properties have demanded rapid development of scanning probe based nanolithographies. Dip pen nanolithography (DPN) and...

Abstract In this work, Ag particles were electrodeposited onto nitrogen-doped graphene oxide, graphene, multi-walled carbon nanotube (MWCNT), and Vulcan XC-72R supports by varying the upper potential limit. The surface morphology of resulting Ag-based catalysts was examined scanning electron microscopy. electrochemical oxygen reduction reaction (ORR) tested in alkaline media employing rotating ...

The results of a study the long-term reproducibility emission characteristics electron sources with field density up to 1000 A/cm 2 based on composite nanocarbon films are presented. It was found that high-current is accompanied by sputtering residual gas ions from atoms cathode material and its sedimentation anode. can be used predict durability diamond-graphite cathodes when operating in unst...

Curved π-conjugated molecules have attracted considerable interest because of the unique properties originating from their curved π surface. However, the synthesis of such distorted molecules requires harsh conditions, which hamper easy access to heteroatom-containing curved π systems. Here we report the synthesis of a π-extended azacorannulene with nitrogen in its centre. The oxidation of 9-am...

Functionalized carbon nanotubes and graphene nanoribbons nanostructures, serving as the basis for the creation of physical pressure and temperature nanosensors, are considered as tools for ecological monitoring and medical applications. Fragments of nanocarbon inclusions with different morphologies, presenting a disordered system, are regarded as models for nanocomposite materials based on carb...
