Capacitive Motors with a High Specific Power Capacity
Optoelectronics, Instrumentation and Data Processing, 2018A new class of capacitive motors based on nanometer gaps between the electrodes and possessing specific power capacity values much higher than that of inductive motors is described. Specific features of their operation are analyzed. The specific energy generated in a cycle of electromechanical conversion is estimated.

Effect of biogas-slurry pyrolysis temperature on specific capacitance
Materials Today: Proceedings, 2018Abstract The purpose of this is study was to investigate the effect of carbonization temperature of biogas slurry on specific capacitance. The biogas derived mesoporous carbon materials were synthesized through carbonization of biogas slurry at 450, 550, and 650 °C followed by activation using KOH at 700 °C for 1 h. The physical characterization done

Honeycomb‐Lantern‐Inspired 3D Stretchable Supercapacitors with Enhanced Specific Areal Capacitance
Advanced Materials, 2018AbstractTraditional stretchable supercapacitors, possessing a thin electrode and a 2D shape, have limited areal specific areal capacitance and are incompatible with 3D wearables. To overcome the limitations of 2D stretchable supercapacitors, it is highly desirable to develop 3D stretchable supercapacitors with higher mass loading and customizable ...

Hydrothermal Synthesis vs Electrodeposition for High Specific Capacitance Nanostructured NiO Films
Electrochemical and Solid-State Letters, 2008NiO nanostructured films were synthesized by hydrothermal and electrodeposition methods at different deposition temperatures. Films fabricated by different methods had similar crystalline structures, but different morphologies. The electrochemical properties of the NiO films were studied by cyclic voltammetry (CV) and electrochemical impedance ...

Biosensors and Bioelectronics, 2013
This paper presents a technique for single-cell electrical property (specific membrane capacitance and cytoplasm conductivity) characterization at a speed of 5-10 cells/s (vs. minutes/cell using existing techniques such as patch clamping and electrorotation). When a cell flows through a microfluidic constriction channel which is marginally smaller than

Facile synthesis of MXene/MnO2 composite with high specific capacitance
Journal of Solid State Electrochemistry, 2018Ti3C2Tx is one of the typical MXene materials, where Tx stands for various surface terminations (OH, O, and/or F groups). In this paper, the delaminated Ti3C2Tx, referred to as d-Ti3C2Tx, and MnO2 composites were prepared by a simple synthesis method. The substrate of the composite is the conductive d-Ti3C2Tx sheet. The MnO2 was grown on the surface of

RGO/KMn8O16 composite as supercapacitor electrode with high specific capacitance
Ceramics International, 2016Abstract Reduced graphene oxide/cryptomelane (RGO/KMn8O16) composites are successfully synthesized from α-MnO2 nanorods and GO using a water-bathing precipitation method. The unique structure of KMn8O16 nanorods, with a length of 2–4 μm, dispersed on the surface of RGO leads to a much enhanced electrical conductivity and ionic transport, finally ...
