A modern cybernetic potentiostat plays a significant role in realizing various electrochemical measurements. This technology report describes general-purpose, scalable, handheld (10 cm2), yet affordable hardware–software framework for potentiostat, galvanostat, and impedance spectrometer with high capabilities: (1) cyclic voltammetry, square-wave (potential-step) chronoamperometry as potentiost...

Corrosion resistance, wear resistance and biocompatibility of the studied Ti–Ta alloys with Ta contents of 10, 30 and 70 mass% together with the currently used metallic biomaterials pure titanium (Ti) and Ti–6Al–4V extra low interstitial (ELI) alloy were investigated for biomedical applications. Corrosion resistance was measured by an anodic polarization test using an automatic potentiostat in ...

We report a high-density electrode array fabricated using complementary metal oxide semiconductor (CMOS) techniques that contains 8,192 individually addressable platinum working electrodes in a 2 mm × 2 mm area along with an on-chip potentiostat. Microfluidic devices were mounted on top of the electrode array to control fluid delivery to evaluate the spatial and temporal resolution achievable w...

The generation of α-ferrocenyl carbocations from ferrocenyl alcohols for S(N)1 substitution at the water-organic solvent interface is initiated by the transfer of protons into the organic phase. The proton flux, and hence the reaction rate, can be controlled by addition of a suitable "phase-transfer catalyst" anion or by external polarization with a potentiostat, providing a new method for the ...

Electrochemical experiments like chronoamperometry or cyclic voltammetry (CV) are essential in the research for novel bioelectrochemical systems. These experiments, executed by a potentiostat, time-consuming which hinders progression. To speed up those this work presents potentiostat with 128 individual parallel stimulation and sensing channels. A channel architecture exploiting time division m...
