Characterization of Mixing in Upflow Solids-Contacting Clarifier
Journal of Environmental Engineering, 1999It has been recognized that flocculation performance can be related to the mixing process. This process has traditionally been described by vessel average parameters such as the root-mean square velocity gradient G¯, which may not represent local mixing conditions within a vessel, particularly in the impeller vicinity. The analysis of turbulence in the

Mechanisms of electriciation in solid-solid contact
1958It is precisely in this area that the greatest confusion exists. Aside from the complications produced by the action of films of moisture, electrolytic effects and/or the formation of electrolytic Helmholtz double layers, or by films of impurity, phenomena are complicated by other factors.

Novel Ion‐to‐Electron Transduction Principle for Solid‐Contact ISEs
Electroanalysis, 2015AbstractSolid‐contact ion‐selective electrodes (SC‐ISEs) are traditionally employed as potentiometric sensors, where the ion activity is related to the zero‐current potential of the sensor versus the reference electrode. In this communication, an alternative ion‐to‐electron transduction principle for SC‐ISEs is introduced.

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

A smartphone sensing system for solid-contact ion-selective electrodes
2019 IEEE International Symposium on Olfaction and Electronic Nose (ISOEN), 2019Developing a portable ion-sensing platform with solid-contact ionselective electrodes (SCISEs) and a smartphone has great potential in on-site ion measurement and electronic tongue applications. Therefore, this study attempted to develop a smartphone-based SCISE sensing system, which integrates SCISEs with a smartphone-based sensing device. SCISEs were

Tribology of Solid Contacts in Magnetic Recording Devices
Applied Mechanics Reviews, 1994The demand for close proximity of magnetic head to the medium during operation of magnetic recording devices, high surface smoothness, and high reliability requires that friction and wear of the head-medium interface be minimized. Friction and wear are minimized by suitable selection of interface materials and lubricants, optimization of surface ...

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.

Fluidization: Gas-solids contacting and bed expansion
Fuel, 1985Abstract In fluidization, the two phases, bubble and particulate, have vastly different velocities and moreover the proportions of these phases alter significantly with changes in fluidizing velocity. These two effects may be combined by the factor (volume flow/velocity) for each of the two phases.
