composite electrodes of polyaniline/mno2-multi walled carbon nanotube (pani/mno2-mwcnt), mno2-mwcnt nanocomposites and mwcnt was produced by the in situ direct coating approach. the supercapacitor performance of the nanocomposites was studied by fourier transform infrared (ft-ir) spectroscopy and scanning electron microscopy (sem). the electrochemical properties of electrodes were also investig...

Introduction Capacitive deionization (CDI), which is ion electrosorption onto the surface of porous materials to remove ions from aqueous solutions, may serve as an energy-efficient alternative for the desalination of brackish water comparing with conventional desalination methods such as membrane separation and thermal distillation [1]. The CDI process operates at low direct voltages. Ions ads...

A sodiothermic reduction method has been developed for the preparation of porous silicon using aluminosilicate zeolite NaY as a precursor. The porous silicon with a specific surface area of approximately 570 m(2) g(-1) shows distinct capacitive behavior when used as an electrode material for supercapacitors.

Ternary hybrid film composed of -zirconium phosphate nanosheet, 1,2-bis(dimethylchlorosilyl)ethane and polypyrrole was prepared by anodic electrodeposition. In the hybrid film, ordered -zirconium nanosheets with grafts by silylation lay down parallel to the substrate and the polypyrrole molecules were intercalated between the nanosheets. The electrochemical measurements confirmed that the hyb...

2. CAPACITIVE SOLUTIONS This paper reviews differential implementations of threshold logic gates, detailing two classes of solutions: capacitive (switched capacitor and floating gate), and conductance/current. The concept underlying capacitive TLGs is the use of an array of capacitors to implement the weighted sum of inputs. The idea was introduced as early as 1966 [6]. Capacitive TLGs can be c...

Abstract In this report, we incorporate activated carbon (AC) onto aluminum substrate via doctor blade method to produce an all-solid-state supercapacitor. The electrochemical properties of the supercapacitor were characterized by cyclic voltammetry and impedance spectroscopy. Galvanostatic charge/discharge tests also carried out exhibit stability AC-based curves showed good capacitive behavior...
