<P><B>Abstract</B></P> <P>This paper reports the effect of electron beam irradiation on CuO thin films synthesized by the successive ionic layer adsorption and reaction (SILAR) method on copper foil for supercapacitor and biocompatibility application. Pristine and irradiated samples were characterized by X-ray diffraction, X-ray photoelectron spectroscopy, field emission scanning electron microscopy, transmission electron microscopy, and electrochemical study. Pristine and irradiated CuO films were pure monoclinic phase, with uniform nanostructures over the whole copper foil. After irradiation, CuO samples had formed innovative nanostructures. Biocompatibility of pristine and irradiated CuO samples suggest that CuO sample is non-toxic and ecofriendly. The specific capacitance of pristine and irradiated CuO strongly depends on surface morphology, and CuO electrodes after irradiation showed superior performance than pristine CuO. The highest specific capacitance of the 20kGy irradiated CuO nanoflowers exceeded 511Fg<SUP>−1</SUP> at 10mVs<SUP>−1</SUP> in 1M KOH electrolyte. Irradiated CuO samples also showed lower ESR, and were superior to other report electrical energy storage materials.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Novel route for the synthesis of pure CuO thin films. </LI> <LI> Different nanostructure of pure CuO and irradiated CuO electrode. </LI> <LI> 20kGy irradiated CuO electrode offer high surface area. </LI> <LI> 20kGy irradiated CuO electrode shows excellent supercapacitive properties. </LI> </UL> </P>

<P><B>Abstract</B></P> <P>In this paper, we chemically synthesized interconnected nanoflake-like CdS thin films for photoelectrochemical solar cell applications and subsequently irradiated them with electron beam irradiation at various doses of irradiation. The as-synthesized and irradiated samples were characterized by means of X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), high-resolution transmission electron microscopy (HR-TEM), and electrochemical measurements. XRD and XPS results confirmed the formation of CdS with a hexagonal crystal structure. FE-SEM and HR-TEM studies confirmed the photoelectrochemical performance, which was dependent on the surface morphology. The calculated values for efficiency demonstrated an outstanding photoelectrochemical performance with a fill factor of 0.38 and efficiency of 3.06% at 30 kGy. The high photoelectrochemical performance may be due to the interconnected nanoflake-like nanostructure and higher active surface area of the CdS samples. These results show that the electron beam irradiation is capable as an electrode for photoelectrochemical solar cells.</P> <P><B>Highlights</B></P> <P> <UL> <LI> First time reported, modified CdS using electron beam irradiation for Solar cell. </LI> <LI> Different size nanostructure of CdS. </LI> <LI> After irradiation CdS sample shows provide more surface area. </LI> <LI> 30 kGy irradiated CdS sample shows excellent solar cell application. </LI> </UL> </P> <P><B>Graphical abstract</B></P> <P>Fill factor/Power conversion efficiency Vs different irradiations doses, pristine and electron irradiated, at 10 kGy, 20 kGy, and 30 kGy.</P> <P>[DISPLAY OMISSION]</P>

Shinde, K.P.,Deshpande, N.G.,Eom, T.,Lee, Y.P.,Pawar, S.H. Elsevier 2010 Materials science and engineering B. Advanced Func Vol.167 No.3

<P>The polycrystalline sample of strontium-doped lanthanum manganite (LSMO) has been synthesized by the solution-combustion method using polyvinyl alcohol as a fuel and magnetocalorific effect in this material is explored. The freshly prepared solution of lanthanum nitrate, strontium nitrate and manganese nitrate was mixed thoroughly and an appropriate amount of fuel was added into the mixture. Thermogravimetric analysis on the as-prepared powder shows phase formation starts at 575 degrees C. From the X-ray diffraction study it is revealed that the crystal structure of LSMO is monoclinic without any other impurity phases. The microstructural investigation presents the growth of material with a grain size in nanometer range. The magnetization as a function of temperature and field for the sample was measured. The change in entropy Delta S-M is found to be 0.425 J/kg K near the Curie temperature of 295 K at 1.5 T. (C) 2010 Elsevier B.V. All rights reserved.</P>

Kolekar, T.V.,Thorat, N.D.,Yadav, H.M.,Magalad, V.T.,Shinde, M.A.,Bandgar, S.S.,Kim, J.H.,Agawane, G.L. Ceramurgica ; Elsevier Science Ltd 2016 CERAMICS INTERNATIONAL Vol.42 No.4

Biocompatible materials based on hydroxyapatite are potentially attractive for a wide range of medical applications. The effect of aluminium substitution on the biocompatibility of hydroxyapatite (HA) under the physiochemical conditions has been investigated. Various samples of aluminium doped hydroxyapatite (Al-HA) with different concentration (0, 0.5, 1.0, 1.5, 2.0, 2.5mol%) were successfully synthesised by solution combustion method and characterized by X-ray Diffraction (XRD), Transmission Electron Microscopy (TEM), and Scanning Electron Microscopy (SEM), and thermal analysis technique. XRD and TEM results reveal uniform and crystalline nature of Al-HA nanoparticles. The biocompatibility of the Al-HA nanoparticles was studied using L929 cell lines by MTT assays up to 24h. These Al-HA nanoparticles are biocompatible on cell lines L929 and do not have toxic effects for further possible in vivo applications. The results of these studies confirmed the biocompatibility of Al-HA and demonstrated the suitability for biomedical applications. The present work reveals the importance of structural, morphological, biocompatible properties of Al-HA nanoparticles and predicts the suitability for biomedical applications.

Vanadium pentoxide (V2O5) mixed tungsten trioxide (WO3) thin films have been synthesized by a novel pulsed spray pyrolysis technique (PSPT) on glass and fluorine doped tin oxide (FTO) coated glass substrates at 400 C. Aqueous solutions of equimolar vanadium chloride and ammonium tungstate were mixed in volume proportions (5%, 10% and 15%) for the deposition of V2O5eWO3 thin films. The structural, morphological, optical and electrochemical properties of V2O5eWO3 thin films were investigated by FT-IR, XRD, SEM, cyclic voltammetry, chronoamperometry and chronocoulometry techniques. The results showed that the electrochemical properties of V2O5 were altered by mixing WO3. All the films exhibited cathodic electrochromism in lithium containing electrolyte (0.5 M LiClO4 þ propylene carbonate (PC)). Maximum coloration efficiency (CE) of about 49 cm2 C1 was observed for the V2O5 film mixed with 15% WO3. The electrochemical stability of the sample was examined and it was found to be stable up to 1000 cycles.

<P><B>Abstract</B></P> <P>In this work, the extraordinary properties of CuO addition on the morphology and supercapacitive performance of Mn<SUB>2</SUB>O<SUB>3</SUB> electrodes were demonstrated. Concisely, CuO/Mn<SUB>2</SUB>O<SUB>3</SUB> thin films were prepared by an easy and inexpensive successive ionic layer adsorption and reaction (SILAR) method. The prepared thin films were characterized by various sophisticated physiochemical systems. The results demonstrated formation of Mn<SUB>2</SUB>O<SUB>3</SUB> thin films with noteworthy morphological alteration upon introduction of CuO. Furthermore, a significant effect of CuO introduction was observed on the electrocatalytic properties of the nanostructured Mn<SUB>2</SUB>O<SUB>3</SUB> electrodes. At 3% CuO doping, the Mn<SUB>2</SUB>O<SUB>3</SUB> electrodes displayed the maximum specific capacitance owing to formation of nanoplate-like structures. The enhanced specific capacitance attained for 3% CuO doping in the Mn<SUB>2</SUB>O<SUB>3</SUB> electrode was 500 F/g at 5 mV/s in a 3 M KOH electrolyte.
