Materials Approaches for Improving Electrochemical Sensor Performance
The Journal of Physical Chemistry B, 2021Electrochemical sensors have emerged as important diagnostic tools in recent years, due to their simplicity and ease of use. Compared to instrumental analysis methods that use complicated experimental and data analysis techniques─such as mass spectrometry, nuclear magnetic resonance (NMR), spectrophotometric methods, and chromatography─electrochemical ...

Simulations of SOFC on electrochemical performance
2010 International Symposium on Computer, Communication, Control and Automation (3CA), 2010Three-dimensional simulations based on a multi-physics model are performed to examine the thermofluidic and electrochemical characteristics of a tubular, anode-supported solid oxide fuel cell (SOFC). The simulations focus on the local transport characteristics of the cathode and anode gases and the distribution of the temperature field within the fuel ...

Electrochemical reduction of graphene oxide and its electrochemical capacitive performance
Journal of Solid State Electrochemistry, 2013A convenient method for the production of graphene is developed using the electrochemical reduction of graphite oxide (GO) in solution without assembling it onto the electrode. The samples were examined by X-ray diffraction, X-ray photoelectron spectroscopy, Fourier transform infrared spectroscopy, and Raman spectroscopy.

The effect of percolation on electrochemical performance
Solid State Ionics, 2000Abstract The effect of percolation on the electrochemical performance of lanthanum strontum manganate (LSM)–yttria-stabilized sirconia (YSZ) composite electrodes was investigated. It was identified that the polarization resistance of the LSM–YSZ composite electrodes is closely related to the connectivity of LSM–YSZ particles and depends on their size

Effect of Electrolyte Cation on the Electrochemical Performance of AC Electrochemical Capacitor
ECS Meeting Abstracts, 2018The aim of this study is to observe the effects of electrolyte cation on the electrochemical performance of anodic electrode in electrochemical capacitor. In an ideal electrochemical capacitor, the symmetrical anodic and cathodic electrodes have the same contribution to overall cell performances.

Electrochemical synthesis and performance of PANI electrode material for electrochemical capacitor
Ionics, 2013Polyaniline (PANI) electrode materials doped with sulfuric acid (H2SO4) were prepared by cyclic voltammetry (CV) method in different reaction conditions. The structure and morphology of PANI samples were characterized by Fourier transform infrared spectroscopy and scanning electron microscope. The electrochemical properties of PANI samples were studied

Electrochemical Performance of Calcium Cobaltite Nano-Plates
Journal of Nanoscience and Nanotechnology, 2009The use of nanostructured materials in Li-ion batteries is desirable from the point of view of achieving enhanced performance, due to the shorter Li-ion diffusion distance and the small dimensional changes upon cycling. Herein, the nanocrystalline calcium cobaltite (Ca3Co4O9) powders were prepared by the Pechini process. The obtained nano-plate powders

Morphology and Electrochemical Performance in Graphite
2000The performance of a graphite electrode in a lithium-ion battery depends on a number of factors. The structure and morphology of graphite greatly influences the lithium intercalation process and is thus decisive in the selection of anode material [1]. It is also known that a decline in capacity on cycling graphite half-cells at high rates is due partly
