Potentiometric Determination of Biogenic Amines Using a Cucurbit[6]uril-PVC Sensing Membrane

Chemosensors
In this work, a potentiometric sensor for the detection of biogenic amines (BAs) in food samples was developed and characterised. The sensor employs a home-fabricated electrode incorporating a cucurbit[6]uril-modified polyvinyl chloride membrane as the ...

Integration of a sensor system into microfluidic chips [PDF]

, 2010
There have been considerable developments in the field of potentiometric sensors in recent years mainly with respect to lowering detection limits and making sensors smaller, solid-state, robust and less expensive.[1, 2] In potentiometric measurements two

Water Drops Sliding Over Arrays of Janus Micropillars With Hydrophilic Tops: A New Mechanism of Drop Charging

Small, EarlyView.
A water drop slides over a distance of a few centimeters across arrays whose top surfaces exhibit a contact angle below 10°. The arrays are fabricated with hydrophilic tops and hydrophobic sidewalls and substrate, forming Janus structures. As the drop moves, it generates a spontaneous electric charge and leaves behind tiny satellite droplets that ...

Efficient Photocatalytic Hydrogen Evolution Enabled by Defect‐ and Interface‐Induced Dual Built‐in Electric Fields in a ZnIn2S4/1T‐2H WS2 Heterojunction

Small, EarlyView.
An N, Sv‐ZnIn2S4/1T‐2H WS2 composite photocatalyst is constructed via an in situ hydrothermal‐solvothermal strategy, simultaneously forming a defect‐induced p‐n homojunction in ZnIn2S4 and a type‐II heterojunction with hybrid 1T/2H WS2. The coupled dual built‐in electric fields promote charge separation and direct photoexcited electrons toward sulfur ...

Influence of an Electromagnetic Field on Direct Reduction of Iron Oxide Using Hydrogen as a Reducing Agent

steel research international, EarlyView.
This study investigates the reduction of pure iron oxides and industrial iron ore using hydrogen gas as a reducing agent. Additionally, to determine whether the reduction process can be accelerated, electromagnetic fields of 50 Hz and 25 kHz were applied.

Potentiometric Determination of Levamisole in Pharmaceutical Formulations by Membrane Sensors Based on Ion-Pair [PDF]

, 2014
The characteristics, performance and application of membrane sensor based on ion-pair Levamisole Picrate are described. The sensor’s response to the levamisole ion has the sensitivity of (38–52) mV/pC over the range of 1•10 5−1•10-1 mol/L, and the ...
