Field effect transistors (FET) have been widely used as transducers in electrochemical sensors for over 40 years. In this report, a FET transducer is compared with the recently proposed bipolar junction transistor (BJT) transducer. Measurements are performed on two chloride electrochemical sensors that are identical in all details except for the transducer device type. Comparative measurements ...

Corrosion is a concern for the oil industry. According to NACE, this phenomenon can cause problems that cost millions of dollars annually, putting people and environment at risk. To combat phenomenon, corrosion-reducing control practices must be implemented. It measured with sensitive tools equipment. As result, current study proposes creating laboratory prototype primary goal simulating dynami...

Nickel or Cobalt-based superalloys represent an important class of engineering materials, finding widespread application in critical components within the gas turbine engines used for jet propulsion and electricity generation. This research aimed at frequency analysis transients electrochemical noise Waspaloy Ultimet superalloys, immersed 3.5 wt.% H2SO4 NaCl solutions two different temperatures...

Physico-chemical continuum battery models are typically parameterized by manual fits, relying on the individual expertise of researchers. In this article, we introduce a computer algorithm that directly utilizes experience researchers to extract information from experimental data reproducibly. We extend Bayesian Optimization (BOLFI) with Expectation Propagation (EP) create black-box optimizer s...
