Qualitative analysis fingertip patterns in ABO blood group

The inheritance of the dermatoglyphic patterns is polygenic. The genetic basis of the blood group is well established. The correlation between the dermatoglyphic patterns and the ABO blood group is studied by some workers in different populations. In the present study, the correlation between dermatoglyphics and ABO blood group is studied in the Marathwada Region of Maharashtra. The qualitative data included fingertip patterns and three indices. It was observed that, the Arch pattern is more common in blood group O both in male and female. Ulnar loop is most common in the blood group AB. Simple whorl and double loop whorl patterns are less frequent in blood group AB. Accidentals were not recorded in blood group A while blood group O show highest percentage of accidentals. Dankmeijer’s index was highest in blood group AB and lowest in blood group B

Morphological tuning of CuO nanostructures by simple preparative parameters in SILAR method and their consequent effect on supercapacitors

Morphology-controlled synthesis of nanomaterials by tuning simple preparative parameters is an impressive path to develop diverse nanostructured materials. Here, we are exploring a successful example of fabrication of hierarchical CuO nanostructures (nanoflakes, nanopetals and diffused nanorods) by simply controlling temperature of reaction bath (3rd beaker) in SILAR method. These CuO nanostructures are further successfully employed as electrode material in supercapacitors. The correlation between electrochemical supercapacitive properties and nanostructures of CuO is investigated in detail. It is revealed that, the supercapacitive properties strongly depend on CuO nanostructures. The specific capacitance values for nanoflakes, nanopetals and diffused nanorods of CuO are found to be 664 F/g, 790 F/g and 695 F/g, respectively at 5 mV/s scan rate. Ragone plot ascertains that CuO nanostructures obtained by SILAR method are potential candidates for high power and high energy density supercapacitors. In addition, EIS analyses show lower ESR values and excellent frequency response for CuO nanostructures.One of the authors (SKS) is grateful to the University Grants Commission (UGC), New Delhi for financial support through the scheme UGC-BSR.

Influence of Mn incorporation on the supercapacitive properties of hybrid CuO/Cu(OH)2 electrodes

Here, we are presenting the effect of Mn doping on the supercapacitive properties of CuO/Cu(OH)2 hybrid electrodes. Briefly, Mn doped CuO/Cu(OH)2 (Mn:CuO/Cu(OH)2) thin films have been synthesized by a successive ionic layer adsorption and reaction (SILAR) method which are further characterized by different physiochemical techniques. Our results revealed the formation of hybrid CuO/Cu(OH)2 thin films with significant morphological deviation through Mn doping. Moreover, considerable positive effect of Mn doping on the electrochemical properties of hybrid CuO/Cu(OH)2 electrodes have been witnessed. Later, the results suggest that at 3% Mn doping in CuO/Cu(OH)2 electrodes with nanoflower-like nanostructures exhibits the highest specific capacitance. The maximum specific capacitance achieved for a 3% Mn:CuO/Cu(OH)2 hybrid electrode is 600 F g-1 at 5 mV s-1 in 1 M Na2SO4 electrolyte. Additionally, a Ragone plot confirms the potential of the Mn:CuO/Cu(OH)2 hybrid electrode for electrical energy storage applications.One of the authors SKS wishes to acknowledge the UGC-SAP DSA-I, New Delhi INDIA for financial support through UGC-BSR scheme.Peer Reviewe

Electrochemical synthesis: Monoclinic Cu2Se nano-dendrites with high performance for supercapacitors

et al.Morphology is a key factor in designing novel nanomaterials with controlled functional properties for the electrochemical application. Herein, we demonstrate the supercapacitor applications of the copper selenide (CuSe) electrodes with different morphologies prepared by electrodeposition at -0.65, -0.75, and -0.85 V/SCE deposition potentials. The well-defined morphologies of the CuSe nanostructures have been useful to develop potential applications in the supercapacitor devices. The nanodendrite-like morphology obtained at the deposition potential -0.75 V/SCE showed maximum specific capacitance (688 F/g at 5 mV/s) as compared to the other morphologies.Analysis of CdSe0.6Te0.4 samples was supported by Dongguk University, Seoul, Korea Research Fund 2016–2018.Peer Reviewe

Enhanced photoelectrochemical properties of nanoflower-like hexagonal CdSe0.6Te0.4: Effect of electron beam irradiation

Present investigation deals with the effect of electron beam irradiation on the photoelectrochemical properties of cadmium selenium telluride (CdSeTe) thin films. Initially, CdSeTe thin films were electrodeposited on fluorine doped tin oxide (FTO) coated glass and stainless steel substrates. Later, these CdSeTe thin films were irradiated with high energy electron beam (10 MeV) of different doses from 10 to 30 kilograys (kGy). The effect of electron beam irradiation on different physico-chemical properties of CdSeTe thin films such as morphological, structural, optical and photoelectrochemical has been investigated. It is observed that, the electron beam irradiation treatment considerably affects the properties of CdSeTe thin films. The surface morphology of CdSeTe thin films was changed from cauliflowers to nanoflowers, nanoroses and interconnected nanoflakes with doses of electron beams. Furthermore, the effect of electron beam irradiation on photoelectrochemical properties of CdSeTe films was investigated. It is interesting to note that, the photoelectrochemical (PEC) properties of CdSeTe thin films are extensively affected by electron beam irradiation. The photoconversion efficiency values of CdSeTe films for different doses of electron beam are found to be 0.9%, 1.1%, 2.0% and 1.5%, respectively.Analysis of CdSe0.6Te0.4 samples was supported by Dongguk University, Seoul, Korea Research Fund 2016–2018.

Electrosynthesis of nanoflower like-ZnS thin films and its characterizations

The thin films of ZnS have been electrodeposited onto stainless steel and ITO coated glass substrate. The films were prepared in aqueous bath, using ZnSO4 and Na2S2O3 as a precursor. The PH of bath maintained throughout the experiment is ~14. The preparative conditions are optimized to get ZnS thin films. The prepared films were further characterized for the structural, morphological and optical properties by X-ray diffraction (XRD), FT-Raman, fourier transform infrared (FTIR) spectroscopy, field emission scanning electron microscope (FE-SEM), energy dispersive spectroscopy (EDAX), atomic force microscopy (AFM), optical absorption spectroscopy, surface wettability studies, respectively. The XRD study shows the formation of ZnS phase with polycrystalline in nature. The nanoflower like morphology is observed for ZnS thin film with thickness 63 nm. FT-IR spectrum of ZnS thin film, were used to investigate the presence of organic compounds, as impurities in the ZnS films. FT-Raman shows the crystal quality and vibration properties of ZnS thin films.The water contact angle measurement shows that the ZnS thin film is hydrophilic in nature. Moreover, the optical study revealed the band gap of 3.13 eV
