Nowadays, more and attention has been paid to flexible electrodes, which can be used make wearable devices so as monitor health signals, such those in ECG, EMG EEG. However, the contact impedance of many membrane electrodes is high due bad fit between sensors skin, or poor sensitivity caused by low conductivity. Therefore, we fabricated a skin-like conductive electrode via electroless silver pl...

the rapidly increasing interest in functional materials with reversibly switchable physico- chemical properties has led to significant work on the development of stimuli responsive membranes. thermotropic liquid crystals with their exceptional properties have potentials for drug-delivery applications. thermoresponsive liquid-crystal-embedded membranes were investigated for the purpose of develo...

we report a pd-co (3:1)/graphene oxide (pd3co /go) catalyst through a one-step strategy. go is synthesized from graphite electrodes using ionic liquid-assisted electrochemical exfoliation. controllable go-supported pd3co electrocatalystis then was reduced by ethylene glycol as a stabilizing agent to prepare highly dispersed pdco nanoparticles on carbon graphene oxide to be used as oxygen reduct...

liquid membrane processes have attracted many interests in recent years for removal of heavy metals such as cadmium from industrial wastewaters. in this study, a modified hybrid liquid membrane system is introduced. the setup is worked by applying the water-insoluble dioctyl phthalate as the organic solvent. n-octanol and tetra butyl ammonium bromide are added to the organic phase to increase t...

Ubiquinone (UQ) is a lipophilic compound present in most living organisms, where UQ's interesting but complex electrochemistry serves an important role the transfer of electrons and protons within across mitochondrial membrane. We briefly review electrochemical characteristics UQ its reduced state, ubiquinol, solution immobilized on electrodes, together with application sensing detection system...

A two-dimensional along-the-channel CFD (computational fluid dynamic) model, coupled with a twophase flow model of liquid water and gas transport for a PEM (proton exchange membrane) fuel cell is described. The model considers non-isothermal operation and thus the non-uniform temperature distribution in the cell structure. Water phase-transfer between the vapour, liquid water and dissolved phas...
