Microcavity Based Solid‐Contact Ion‐Selective Microelectrodes
Electroanalysis, 2006AbstractA novel design and fabrication procedure is proposed for the preparation of robust ionophore based ion‐selective microelectrodes. The essential component of the new design is a microcavity that is formed after recessing a voltammetric inlaid disk type gold microelectrode by chemical etching of the gold microwire. The microcavity of ca.

Measurement of liquid-solid contact in boiling
Journal of Physics E: Scientific Instruments, 1986A new method of measuring contact in boiling is described. This involves coating the surface with a thin electrically insulating layer. The impedance measured through this layer, between the metal substrate and the boiling liquid, is related to the average fraction of the heat transfer area that is wetted by the liquid.

Journal of Environmental Engineering, 2004
The trickling filter/solids contact ~TF/SC! process was developed in the late 1970s to improve the quality of the final effluent from existing trickling filter plants, to be able to meet stricter Environmental Protection Agency effluent requirements. Although this process has successfully achieved this objective, it is still not completely understood ...

Bioadhesion to solids: contact angle hysteresis effect
Colloid and Polymer Science, 2012It was recently reported that the ease of removal of sporelings of green seaweed Ulva under shear stress from the polymer surfaces was found to be linearly and positively correlated with contact angle and wetting hysteresis, i.e., the higher the hysteresis, the greater the removal.

Effect of liquid-solid contact angle on droplet evaporation
Fire Safety Journal, 1996The effect of varying initial liquid-solid contact angle on the evaporation of single droplets of water deposited on a stainless steel surface is studied using both experiments and numerical modeling. Contact angle is controlled in experiments by adding varying amounts] (100 and 1000 ppm) of a surfactant to water.

Direct Solid Contact in Reference Electrodes
2013As a part of the electrodes used in galvanic cells, the role of direct (internal) contact is to facilitate communication between the meter and the electrochemical cell. This is usually solid contact (SC) and is referred to by names such as solid contact ion-selective electrodes (SC ISEs) or solid contact reference electrodes (SC REs).

Solid-Contact Electrochemical Polyion Sensors for Monitoring Peptidase Activities
Analytical Chemistry, 2007We report here on improved solid-contact electrochemical polyion sensors for the detection of polyion protamine. The polymeric membrane sensors were fabricated with a conducting polymer as an ion-electron transduction layer. We observed that decreasing the magnitude of the applied current pulse caused a significant improvement of the sensor sensitivity

New Signal Readout Principle for Solid-Contact Ion-Selective Electrodes
Analytical Chemistry, 2016A novel approach to signal transduction concerning solid-contact ion-selective electrodes (SC-ISE) with a conducting polymer (CP) as the solid contact is investigated. The method presented here is based on constant potential coulometry, where the potential of the SC-ISE vs the reference electrode is kept constant using a potentiostat. The change in the

Solid‐Contact Reference Electrodes Based on Lipophilic Salts
Electroanalysis, 2009AbstractA novel solid‐contact reference electrode (SCRE) for potentiometric measurements is studied. A lipophilic salt was introduced into a PVC membrane by two different approaches, i) using tetra(alkyl)ammonium‐tetra(butyl or phenyl)borate, i.e. a single salt (Φ+Ψ−), and ii) tetra(alkyl)ammonium chloride+potassium tetra(phenyl)borate i.e.
