Interfacial Interaction in MeO/MWNTs (Me-Cu, Ni) Nanostructures as Efficient Electrode Materials for High-Performance Supercapacitors.

Due to their unique physical and chemical properties, complex nanostructures based on carbon nanotubes and transition metal oxides are considered promising electrode materials for the fabrication of high-performance supercapacitors with a fast charge rate, high power density, and long cycle life. The crucial role in determining their efficiency is played by the properties of the interface in such nanostructures, among them, the type of chemical bonds between their components. The complementary theoretical and experimental methods, including dispersion-corrected density functional theory (DFT-D3) within GGA-PBE approximation, scanning electron microscopy (SEM), X-ray diffraction (XRD), Raman, X-ray photoelectron, and X-ray absorption spectroscopies, were applied in the present work for the comprehensive investigation of surface morphology, structure, and electronic properties in CuOx/MWCNTs and NiO/MWCNTs.

Fabrication of Ni-Polyaniline/Graphene Oxide Composite Electrode with High Capacitance and Water Splitting Activity.

The Ni-PANI@GO composite electrode was fabricated via cost effective electrodeposition technique. According to the XRD, FTIR, Raman, SEM, and XPS analyses revealed that the nickel doped PANI@GO composite has been fabricated on the surface of the nickel foam. Addition of nickel significantly enhanced interaction between graphene with PANI leading to higher degree of polyaniline doping though imine groups.

[Morphological and immunological comparisons in epilepsy].

Morphological and immunological assays were employed to examine 18 epileptic patients and 40 Krushinskiĭ-Molodkina rats undergoing subconvulsive and convulsive acoustic stimulations. After multiple audiogenic epileptiform convulsive fits the epileptogenic areas of the brain of epileptic patients (biopsy material) and the neocortex of the sensorimotor area, amygdaloid complex and hippocampus of rats manifested vascular alterations in the form of chronic or subacute vasculitis. The changes revealed in the ratio of B and T lymphocytes in the peripheral blood of the epileptic patients in combination with pronounced stimulation of cellular and humoral immunity responses to antigens of homologous and autologous brain extracts, more well-defined in marked inflammatory process, may attest to the immune genesis of endo- and perivasculitis.
