BCN: A Graphene Analogue with Remarkable Adsorptive Properties

Raidongia, Kalyan; Nag, Angshuman; Hembram, K P S S; Waghmare, Umesh V; Datta, Ranjan; Rao, C N R (Wiley-VCH Verlag GmbH, 2010)

A new analogue of graphene containing boron, carbon and nitrogen (BCN) has been obtained by the reaction of high-surface-area activated charcoal with a mixture of boric acid and urea at 900 degrees C. X-ray photoelectron ...
Graphene analogues of BN: novel synthesis and properties

Nag, Angshuman; Raidongia, Kalyan; Hembram, Kailash P S S; Datta, Ranjan; Waghmare, Umesh V; Rao, C N R (The American Chemical Society, 2010-03)

Enthused by the fascinating properties of graphene, we have prepared graphene analogues of BN by a chemical method with a control on the number of layers. The method involves the reaction of boric acid with urea, wherein ...
Investigations of nanostructures of BN,BCN and other inorganic materials

Raidongia, Kalyan (Jawaharlal Nehru Centre for Advanced Scientific ResearchChemistry and Physics of Materials Unit (CPMU), 2011)

The thesis consists of seven chapters, of which the first chapter presents a brief overview of nanomaterials. Chapter 2 deals with the transformations of elemental nanowires of metals and silicon to nanotubes of the ...
Multiferroic and magnetoelectric properties of core-shell CoFe2O4 @ BaTiO3 nanocomposites

Raidongia, Kalyan; Nag, Angshuman; Sundaresan, A; Rao, C N R (American Institute of Physics, 2010-08-09)

Core-shell CoFe2O4@BaTiO3 nanoparticles and nanotubes have been prepared using a combination of solution processing and high temperature calcination. Both the core-shell nanostructures exhibit magnetic and dielectric ...
Study of the Transformations of Elemental Nanowires to Nanotubes of Metal Oxides and Chalcogenides through the Kirkendall Effect

Raidongia, Kalyan; Rao, C N R (American Chemical Society, 2008-09-04)

We have employed the Kirkendall effect to transform elemental nanowires of metals and silicon to nanotubes of the corresponding oxides and chalcogenides, having prepared the metal nanowires by nebulized spray pyrolysis of ...
Synthesis and characterization of inorganic nanorods and nanotubes and kirkendall effect-induced transformations of metal nanowires of oxide or chalcogenide nanotubes

Raidongia, Kalyan (Jawaharlal Nehru Centre for Advanced Scientific ResearchChemistry and Physics of Materials Unit (CPMU), 2007)

Abstract not available
Synthesis, structure and properties of homogeneous BC4N nanotubes

Raidongia, Kalyan; Jagadeesan, Dinesh; Upadhyay-Kahaly, Mousumi; Waghmare, U V; Pati, Swapan K; Eswaramoorthy, M; Rao, C N R (The Royal Society of Chemistry, 2008)

BCN nanotube brushes have been obtained by the high temperature reaction of amorphous carbon nanotube (a-CNT) brushes with a mixture of boric acid and urea. The a-CNT brushes themselves were obtained by the pyrolysis of ...
Synthesis, Structure, and Properties of Mesoporous B/C/N Microspheres

Raidongia, Kalyan; Hembram, K P S S; Waghmare, Umesh V; Eswaramoorthy, M; Rao, C N R (Wiley-VCH Verlag Gmbh, 2010)

Reaction of low surface area carbon with a mixture of urea and boric acid at 930 degrees C yields a composition close to BC4N with a graphitic structure. BC4N was characterized by electron energy loss spectroscopy, X-ray ...
