Al3+-Potentiometric sensor, based on (2Z) -methyl 2- ((z) (p-tolylimino)-3-ethyl -4-oxothiazolidin -5- ylidene) Acetate (MTEOY) as a neutral ionophore, was successfully developed for the detectionof Al3+ in aqueous solutions. The electrode responds to Al3+ ion with a sensitivity of 19.8 ± 0.1 mV/decade over the range 1.0 x 10-8- 1.0 x 10-1 mol LT' and in a pH range of 3.0-9.0. The electrodeshow...

The present study investigated the role of tonal context (extrinsic information) in the perception of Cantonese lexical tones. Target tones at three separate positions (initial, medial and final position) were recorded by two speakers (one male and one female). These sentences were edited and presented in three conditions: original carrier (target within the original context), isolation (target...

The hydrogen economy presents an appealing energy future but its implementation must solve numerous problems ranging from low-cost sustainable production, high-density storage, costly infrastructure, to eliminating safety concern. The use of renewable carbohydrate as a high-density hydrogen carrier and energy source for hydrogen production is possible due to emerging cell-free synthetic biology...

Several Na+-dependent carriers of amino acids exist on the abluminal membrane of the blood-brain barrier (BBB). These Na+-dependent carriers are in a position to transfer amino acids from the extracellular fluid of brain to the endothelial cells and thence to the circulation. To date, carriers have been found that may remove nonessential, nitrogen-rich, or acidic (excitatory) amino acids, all o...

Polymer-supported liquid-crystal membranes have been designed for neutral-carrier-type potassium ion-selective electrodes, aiming for practical applications of high-performance liquid-crystalline membrane ion sensors. Two types of polymer-supported liquid-crystal membranes were tested for their usefulness; one is microporous poly(tetra fluoroethylene) (PTFE) membranes impregnated by thermotropi...
