Pressure Pulses Generated by Wire‐Guided Discharges in Water

open access: yesHigh Voltage, EarlyView.
ABSTRACT The hydrodynamic characteristics of underwater wire‐guided discharges and their relationships with the wire length and pulsed circuit parameters are not fully understood. In this paper wire‐guided discharges using wires of length 3, 5 and 7 cm and diameter of 0.05 mm have been investigated. The energy available to the discharges was 162.3 J at

Tunable Optical Sensing with PVC-Membrane-Based Ion-Selective Bipolar Electrodes

open access: yesACS Sensors, 2019
We show here that the response of ion-selective membrane electrodes (ISEs) based on traditional PVC membranes can be directly translated to a colorimetric readout by a closed bipolar electrode (BPE) arrangement. Because the resulting optical response is based on the turnover of the redox probe, ferroin, dissolved in a thin layer compartment, it ...
