  • 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 ...
  • Blue light emitting graphene-based materials and their use in generating white light 
    Subrahmanyam, K S; Kumar, Prashant; Nag, Angshuman; Rao, C N R (Pergamon-Elsevier Science Ltd, 2010-10)
    It has been demonstrated that acid-treated graphene samples as well as reduced graphene oxide show fairly intense blue emission centered around 440 nm. Reduction of graphene oxide can be carried out either chemically or ...
  • Electronic grade and flexible semiconductor film employing oriented attachment of colloidal ligand-free PbS and PbSe nanocrystals at room temperature 
    Shanker, G. Shiva; Swarnkar, Abhishek; Chatterjee, Arindom; Chakraborty, S.; Phukan, Manabjyoti; Parveen, Naziya; Biswas, Kanishka; Nag, Angshuman (Royal Society of Chemistry, 2015)
    Electronic grade semiconductor films have been obtained via the sintering of solution processed PbS and PbSe nanocrystals at room temperature. Prior attempts to achieve similar films required the sintering of nanocrystals ...
  • 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 ...
  • Inorganic Analogues of Graphene 
    Rao, C N R; Nag, Angshuman (Wiley-VCH Verlag GmbH, 2010-09)
    The discovery of graphene has aroused great interest in the properties and phenomena exhibited by two-dimensional inorganic materials, especially when they comprise only a single, two or a few layers. Graphene-like MoS2 ...
  • 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 ...
  • Visible light-induced hydrogen generation using colloidal (ZnS)(0.4)(AgInS2)(0.6) nanocrystals capped by S2- ions 
    Jagadeeswararao, Metikoti; Dey, Sunita; Nag, Angshuman; Rao, C. N. R. (Royal Society of Chemistry, 2015)
    (ZnS)(0.4)(AgInS2)(0.6) nanocrystals (NCs) capped by S2- ions exhibit interesting electronic properties, absorbing visible light along with a suitable band alignment as well as properties such as high surface area providing ...
