A selective electrochemical method for the determination of uric acid was developed by using nano poly cresol red modified glassy carbon electrode. This new material has been characterized by Scanning Electron Microscopy, cyclic voltammetry and Differential pulse voltammetry. This modified electrode shows excellent electrocatalytic activity towards the oxidation of uric acid in the presence of ...

Little is known about the importance and/or mechanisms of biological mineral oxidation in sediments, partially due to the difficulties associated with culturing mineral-oxidizing microbes. We demonstrate that electrochemical enrichment is a feasible approach for isolation of microbes capable of gaining electrons from insoluble minerals. To this end we constructed sediment microcosms and incubat...

introduction thermal processing has a huge impact on the textural attribute of the final food product and texture is a major factor contributing the overall quality of food. ohmic heating is an advanced thermal processing method in which heat is internally generated within foods by passing an alternating electric current through them. ohmic heating can volumetrically heat the entire mass of a f...

fabrication and electrochemical characterization of a sensor for the determination of epinephrine (ep), uric acid (ua) and folic acid (fa) is described. the sensor  was prepared using carbon paste electrode (cpe) modified with 3,4-dihydroxybenzaldehyde-2,4-dinitrophenylhydrazone (ddp) and carbon nanotubes (cnts), which makes the modified electrode highly sensitive for the electrochemical detect...

in this paper, multi-wall carbon nanotubes (mwcnts), gold nanoparticles (gnp) and glucose oxidase (god) was developed for the specific detection of glucose. mwcnts were chemically modified with the h2so4–hno3 pretreatment to introduce carboxyl groups which were used to interact with the amino groups of poly(allylamine) (paa) and cysteamine via 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide/n-hy...

This comprehensive paper, Electrode Potentials Part 2, is a continuation of 1: Fundamentals and Aqueous Systems. Determining the electrode potential crucial for understanding nature electrochemical properties materials or systems; however, an accurate evaluation target has always been challenge. The can be used to predict reaction mechanisms in electrochemistry directly applied study applicatio...

The solid electrolyte interphase (SEI) is arguably one of the most critical components Li-ion cell. Despite decades studies SEI, its intrinsic complexity and lack suitable characterization tools still prevent a real consensus on governing mechanisms to be reached. Herein, operando Raman spectroscopy supported by complimentary online electrochemical mass spectrometry employed study SEI formation...

Carbon-electrode-based perovskite solar cells (C-PSCs) are promising candidates for commercialization due to their high stability. However, the absence of a hole selective layer (HSL) often limits performance, yielding low fill factors (FFs). Herein, certified FF 78.8% obtained through HSL-free C-PSCs is focused. This found approach highest values reported metal-electrode-based PSCs employing h...

A sodium dodecyl sulfate modified carbon paste electrode (SDS/CPE) was developed in this work based on the surface modification method. The modified electrode was prepared by immersing SDS/CPE in a nickel nitrate solution. This electrode showed a strong accumulation ability toward nickel ions. Then modified electrode was conditioned by potential recycling in a potential range of 0.2–0.8 V (vs. ...
