High resolution transmission electron microscopy (HRTEM), energy-dispersive x-ray spectroscopy (EDAX), vibrating sample magnetometry (VSM), Fourier transform infrared spectroscopy (FTIR), diffuse reflectance spectroscopy (DRS) and fluorescence microscopy are used to characterize the constitution, size, composition and physical properties of these superparamagnetic-fluorescent nanoparticles. These CdTe decorated magnetite nanoparticles were then functionalized with anti-epidermal growth factor receptor (EGFR) antibody to specifically target cells expressing this receptor. The EGFR is a transmembrane glycoprotein and is expressed on tumor cells from different tissue origins including human leukemic cell line Molt-4 cells. The magnetite-CdTe composite nanosystem is shown to perform excellently for specific selection, magnetic separation and fluorescent detection of EGFR positive Molt-4 cells from a mixed population. Flow cytometry and confocal laser scanning microscopy results show that this composite nanosystem has great potential in antibody functionalized magnetic separation and imaging of cells using cell surface receptor antibody.</p>1 aKale, Anup1 aKale, Sonia1 aYadav, Prasad1 aGholap, Haribhau1 aPasricha, Renu1 aJog, Jyoti, Prakash1 aLefez, Benoit1 aHannoyer, Beatrice1 aShastry, Padma1 aOgale, Satishchandra, B.  uhttps://library.ncl.res.in/content/magnetitecdte-magnetic-fluorescent-composite-nanosystem-magnetic-separation-and-bio-000924nas a2200253   4500008004100000022001400041245009700055210006900152260007700221300001400298490000600312653002100318653001900339653001300358653002100371653002000392100001800412700002000430700002100450700002400471700002400495700002500519856012600544       2012                        eng d  a1864-563100a3D Hexaporous carbon assembled from single-layer graphene as high performance supercapacitor0 a3D Hexaporous carbon assembled from singlelayer graphene as high  aBOSCHSTRASSE 12, D-69469 WEINHEIM, GERMANYbWILEY-V C H VERLAG GMBHcOCT  a2159-21640 v510aElectrochemistry10aEnergy storage10agraphene10aporous materials10aSupercapacitors1 aYadav, Prasad1 aBanerjee, Abhik1 aUnni, Sreekuttan1 aJog, Jyoti, Prakash1 aKurungot, Sreekumar1 aOgale, Satishchandra  uhttps://library.ncl.res.in/content/3d-hexaporous-carbon-assembled-single-layer-graphene-high-performance-supercapacitor-001333nas a2200229   4500008004100000022001400041245004900055210004900104260010600153300001400259490000800273520058400281653002300865653001200888653001400900653001900914100001800933700002100951700002400972700002900996856007801025       2012                        eng d  a0038-109800aCarbon nanoscrolls by pyrolysis of a polymer0 aCarbon nanoscrolls by pyrolysis of a polymer  aTHE BOULEVARD, LANGFORD LANE, KIDLINGTON, OXFORD OX5 1GB, ENGLANDbPERGAMON-ELSEVIER SCIENCE LTDcDEC  a2092-20950 v1523 a<p>3D network of carbon nanoscrolls was synthesized starting from pyrolysis of poly(acrylic acid-co-maleic acid) sodium salt. It is a catalyst-free process where pyrolysis of polymer leads to formation of carbon form and sodium carbonate. Upon water soaking of pyrolysis product, the carbon form undergoes self-assembly to form carbon nanoscrolls. The interlayer distance between the walls of carbon nanoscroll was found to be 0.34 nm and the carbon nanoscrolls exhibited a surface area of 188 m(2)/g as measured by the BET method.

The dense self-organized morphology of Co0.85Se HNWs is revealed by scanning/transmission electron microscopy. The as-synthesized Co0.85Se HNWs possess high pseudocapacitive property with high capacitance retention and high durability. The areal capacitance value is seen to vary from 929.5 to 600 mF cm(-2) (60% retention) as the current density is increased from 1 to 15 mA cm(-2), an increase of a factor of 15. Based on mass loading, this corresponds to a very high gravimetric capacitance of 674 (for 2 mA cm(-2) or 1.48 Ag-1) and 444 Fg(1-) (for 15 mA cm(-2) or 11 A g(-1)) in a full-cell configuration with the Co0.85Se HNWs as cathode and activated carbon as anode (asymmetric configuration) promising results are obtained.</p>10aasymmetric supercapacitor10acarbon fiber paper10acobalt selenide10ahydrothermal10apseudocapacitor10aselenization1 aBanerjee, Abhik1 aBhatnagar, Sumit1 aUpadhyay, Kush, Kumar1 aYadav, Prasad1 aOgale, Satishchandra  uhttps://library.ncl.res.in/content/hollow-co085se-nanowire-array-carbon-fiber-paper-high-rate-pseudocapacitor-001814nas a2200217   4500008004100000022001400041245012500055210006900180260010600249300001200355490000700367520095400374100001901328700002701347700001801374700001801392700002001410700002401430700002501454856011701479       2014                        eng d  a0008-622300aOligomer-salt derived 3D, heavily nitrogen doped, porous carbon for Li-ion hybrid electrochemical capacitors application0 aOligomersalt derived 3D heavily nitrogen doped porous carbon for  aTHE BOULEVARD, LANGFORD LANE, KIDLINGTON, OXFORD OX5 1GB, ENGLANDbPERGAMON-ELSEVIER SCIENCE LTDcDEC  a462-4710 v803 a<p>3D high surface area porous carbon is seen to form via self assembly of porous graphene sheets by direct pyrolysis of an oligomer salt tailored for the realization of molecular level activation. The oligomer salt was derived from 4-amino benzoic acid as the monomer by a facile free radical polymerization process. Incorporation of the functional groups (-COONa) eliminate the need for any external activating agents (KOH, ZnCl2, etc.) and also render high degree of sub-nanoscale homogeneity. This oligomer derived carbon (ODC) exhibits efficient performance in non-aqueous charge storage application namely Li-ion hybrid electrochemical capacitor (Li-HEC) owing to its high surface area, 3D interconnectivity and an appropriate pore size distribution. The Li-HEC fabricated with ODC based electrodes delivered a maximum energy density of similar to 63 Wh kg(-1) with spinel L4Ti5O12 as the anode. (C) 2014 Elsevier Ltd.

The composite is prepared by the solution casting method and its constituents are optimized as 15 wt% SLGAPC and 20 wt% Fe3O4 through a novel solvent relaxation nuclear magnetic resonance experiment. The PVA-SLGAPC-Fe3O4 composite shows high dielectric permittivity in the range of 1 Hz-10 MHz, enhanced by a factor of 4 as compared to that of the PVA-SLGAPC composite, with a reduced loss by a factor of 2. The temperature dependent dielectric properties reveal the activation energy behaviour with reference to the glass transition temperature (80 degrees C) of PVA. The dielectric hysteresis with the temperature cycle reveals a remnant polarization. The enhanced dielectric properties are suggested to be the result of improvement in the localized polarization of the integrated interface system (Maxwell-Wagner-Sillars (MWS) polarization) formed by the uniform adsorption of Fe3O4 on the surface of SLGAPC conjugated with PVA. The EMI shielding property of the composite with a low thickness of 0.3 mm in the X-band (8.2-12.4 GHz) shows a very impressive shielding efficiency of similar to 15 dB and a specific shielding effectiveness of 20 dB (g cm(-3))(-1), indicating the promising character of this material for flexible EMI shielding applications.</p>1 aRao, B., V.
