The chemical composition and microstructure of the material have been characterized using ICP-AES, FT-IR, XRD, FESEM, TEM and XPS. The supercapacitor properties of the MF-Fe-C are studied in detail. A thorough comparison of the supercapacitor performances of MF-Fe-C and bare MF-C has been carried out through detailed electrochemical characterisations employing both two and three-electrode techniques. The nanohybrid showed an enhanced energy density of 127.75 WhKg⁻¹, specific capacitance of ∼408 F g⁻¹ at 1 mVs⁻¹ scan rate, and excellent cyclic stability even after 1000 charge-discharge cycles, making it an intriguing material for high energy density supercapacitor devices.</p>1 aRatha, Satyajit1 aVernekar, Dnyanesh1 aSivaneri, Kavin1 aJagadeesan, Dinesh1 aRout, Chandra, Sekhar  uhttps://library.ncl.res.in/content/iron-carbon-nanohybrid-particles-environmentally-benign-electrode-supercapacitor02374nas a2200193   4500008004100000022001400041245017000055210006900225260000800294300001400302490000800316520160800324100002501932700002101957700002901978700002402007700002602031856012302057       2018                        eng d  a1520-610600aImproved nonenzymatic glucose sensing properties of Pd/MnO2 nanosheets: synthesis by facile microwave-assisted route and theoretical insight from quantum simulations0 aImproved nonenzymatic glucose sensing properties of PdMnO2 nanos  cAUG  a7636-76460 v1223 a<p>The electrocatalytic properties of manganese oxide (MnO2) can be improved significantly by making hybrids/composites with noble metals (Au, Pd). Here, efforts have been made to synthesize the MnO2/Au and MnO2/Pd nanocomposites by a facile, rapid microwave irradiation method. The products characterized by X-ray diffraction and transmission electron microscopy exhibited their tetragonal phase and nanosheet morphology. The efficiency of the prepared composite materials as glucose sensor was tested by cyclic voltammetry and chronoamperometry measurements, and the results are discussed. The study revealed that successful modification of MnO2 by Pd led to excellent sensing performance by the reduction of size and the synergistic effect between MnO2 and PdO, which expedites the electron transfer. Besides, the wide detection range, good selectivity, and stability demonstrate its robustness in the design of electrochemical sensor platform. To get theoretical insight into the excellent sensing performance of MnO2/Pd, we have performed detailed density functional theory simulations to explore the charge transfer and bonding mechanism of glucose on MnO2 and Pd/Au-doped MnO2 surface. Pd is bonded strongly on MnO2 and makes MnO2/Pd more conducting due to the enhancement of density of states near Fermi level. The higher binding energy of glucose and enhanced charge transfer from glucose to Pd-doped MnO2 compared to bare MnO2 infer that Pd-doped MnO2 possess superior charge-transfer kinetics, resulting in higher glucose sensing performance, which supports our experimental observations.</p>1 aPonnusamy, Rajeswari1 aGangan, Abhijeet1 aChakraborty, Brahmananda1 aLate, Dattatray, J.1 aRout, Chandra, Sekhar  uhttps://library.ncl.res.in/content/improved-nonenzymatic-glucose-sensing-properties-pdmno2-nanosheets-synthesis-facile
