The electrochemistry of mixed conductors is outlined. In particular the impact of grain boundaries on the transport perpendicular to the grain boundary plane is studied. Fe-doped SrTiO3 bicrystals were used as prototype mixed conductor. Experimental results obtained by optical spectroscopy (chemical diffusion) and electrochemical impedance spectroscopy (electrical transport) are analysed in ter...

We present a microscale cell culture system with an interdigitated microarray of excimer-laser-ablated indium tin oxide electrodes for electrical stimulation of cultured cells. The system has been characterized in a range of geometeries and stimulation regimes via electrochemical impedance spectroscopy and used to culture primary cardiomyocytes and human adipose derived stem cells. Over 6 days ...

Graphene is a promising material possessing features relevant to bioelectronics applications. Graphene microelectrodes (GMEAs), which are fabricated in a dense array on a flexible polyimide substrate, were investigated in this work for their performance via electrical impedance spectroscopy. Biocompatibility and suitability of the GMEAs for extracellular recordings were tested by measuring elec...

This paper presents a label-free and noninvasive cell-counting assay system for electrical diagnostic tests of Falciparum malaria using electric impedance spectroscopy (EIS). Our system enabled a high-throughput test in a compact form-factor by the integration of a microfluidic device and a custom circuit board. Based on the differentiation of dielectric properties between cells and container m...

Copper oxide (CuO) nanostructures are of particular interest because of their interesting properties and promising applications in batteries, super capacitors, solar cells, gas sensors, bio sensors, nano fluids and catalysis. In Recent past, more efforts have been received to design materials with different properties which is dependent on morphology.  In this work cupric oxide nano flakes were...

The paper aims on the investigations of corrosion processes of three different porcelain fused to metal dental crowns with CoCrMo frameworks. The three crowns, with different exposed metal surfaces, were investigated using electrochemical impedance spectroscopy (EIS), through 168 hours of experiment. The data were analyzed and the influence of corrosion processes was shown after the crowns were...
