Impedance spectroscopy quantifies microplastics waste in waterways

An Electrochemical Impedance Spectroscopy System for Monitoring Pineapple Waste Saccharification

Electrochemical impedance spectroscopy (EIS) has been used for monitoring the enzymatic pineapple waste hydrolysis process. The system employed consists of a device called Advanced Voltammetry, Impedance Spectroscopy & Potentiometry Analyzer (AVISPA) equipped with a specific software application and a stainless steel double needle electrode. EIS measurements were conducted at different sacc...

Frequency of electronics-waste generated heavy metals in urban waterways

Heavy metals are one of the dreadful environmental pollutants. Its toxicity is a menace to the ecosystem and has attracted global concern over the decades. The attendant uncontrolled disposal and recycling of electronic-waste (e-waste) has greatly influence the elevated concentration of heavy metals observed in Nigeria waterways. This study was carried out to investigate the frequency of the de...

Review Article: Application of Electrical Impedance Spectroscopy in Bladder Cancer Screening

Introduction Bladder cancer is the most common malignancy in elderly people and most bladder cancers are transitional cell carcinomas (TCC). Bladder pathology is usually investigated visually by cystoscopy and this technique can represent different conditions ranging from simple inflammation to flat CIS. However, biopsies must be taken from the suspected area to obtain diagnostic information. T...

Impedance Spectroscopy of Thin Films

Single Crystal by Impedance Spectroscopy

Bi 4 Ge 3 O 12 (bismuth germanate – BGO) single crystals were produced by the Czochralski technique and their electrical and dielectric properties were investigated by impedance spectroscopy. The isothermal ac measurements were performed for temperatures from room temperature up to 750 °C, but only the data taken above 500 °C presented a complete semicircle in the complex impedance diagrams. Ex...
