Schiff base (E)-2-methyl-N-(tetrazolo[1,5-a]quinolin4-ylmethylene)aniline (QMA) was synthesized, and its inhibitive effect for mild steel in 1N HCl solution was investigated by weight loss measurement and electrochemical tests. From the weight loss measurements and electrochemical tests, it was observed that the inhibition efficiency increases with the increase in the Schiff base concentration ...

ABSTRACT We report a novel signal amplification strategy integrated into a microfluidic paper-based electrochemical immunodevice to perform multiplexed measurement of cancer biomarkers. The signal amplification was achieved by using graphene to modify the immunodevice surface to accelerate electron transfer and silica nanoparticle as a tracing tag to label signal antibodies. Accurate, rapid, si...

We demonstrate the ability to apply electron energy loss spectroscopy (EELS) to follow the chemistry and oxidation states of LiMn2O4 and Li4Ti5O12 battery electrodes within a battery solvent. This is significant as the use and importance of in situ electrochemical cells coupled with a scanning/transmission electron microscope (S/TEM) has expanded and been applied to follow changes in battery ch...

Among the techniques of detection used in clinical chemistry, optical and electrochemical methods are especially attractive. However, except for glass electrodes for pH measurement, potentiometric electrochemical sensors (ionselective electrodes) gained general acceptance in clinical analyzers and in clinical instrumentation, respectively, only around 1970 (for reviews see 1-5). Here we report ...

Electrochemical impedance spectroscopy (EIS) is a widely used method for battery tests in manufacturing and automotive field applications. As such, accurate measurement of the over broad frequency spectrum high relevance, also requiring specific calibration methods evaluation error bounds. Here, we report first time comprehensive uncertainty analysis calibrated EIS batteries. We aim to identify...

abstract background: heavy metals in industrial wastewater especially chromium (vi) are considered as the main environmental pollutants. methods: electrochemical cell made of plexiglass with a volume of 1.95 lit was used. iron and graphite electrodes, electricity conductor, each with dimensions of 0.1×3×10 cm (width×length×height) were designed and built. tests were carried out in various condi...
