In engineering practice, the two-dimensional chloride diffusion is encountered frequently. This paper proposes a rapid experimentation method for two-dimensional diffusion of chloride in concrete. A device is developed for the experiment, based on which the sampling can be performed with two-dimensional locating in the specimens. The improved Volhard titration method was presented for extractio...

Propofol is multiple influences on organism function that could affect gene expressions of ion channels, cause arhythmia, impair brain cognitive functions, inhibit energy metabolism and increase hypoxic tolerance. To evaluate whether these phenomena might still exist in persistent low concentration of propofol exposure. We investigated changes in the mRNA levels of Daphnia 120 ion channel genes...

Chloride and sodium are the main ions contributing to soil salinity in many regions but chloride is an essential element necessary for plant growth and development. It also controls the growth of some pathogens in plants. In this experiment, the effect of the chloride ion in nutrient solution on yield and fruit quality of two strawberry cultivars: ‘Selva’ and ‘Camarosa’ grown in hydroponic cult...

A fall in extracellular pH increased membrane conductance of the giant cell in the abdominal ganglion of Aplysia californica. Chloride conductance was trebled whereas potassium conductance was increased by 50%. Half the giant cells were hyperpolarized (2-8 mv) and half were depolarized (3-10 mv) by lowering the pH. The hyperpolarizing response always became a depolarizing response in half-chlor...

The dissolution of 1-alkyl-3-methylimidazolium chloride ILs with short alkyl chains in trihexyltetradecylphosphonium chloride does not only exhibit a large negative entropy. Also, in the resulting mixtures, the phosphonium cation diffuses faster than the much smaller imidazolium cation. Both unexpected features originate from the formation of a large symmetric ion cluster cage in which the imid...

A ditopic, macrobicyclic receptor with adjacent anion and cation binding sites is able to distinguish between various monoalkylammonium salts by binding them as contact ion-pairs. The affinity for linear n-propylammonium chloride is at least 2 orders of magnitude greater than that for n-propylammonium acetate, n-propylammonium p-toluenesulfonate, and branched isopropylammonium chloride. An X-ra...

In this paper, research into the fabrication and characterization of a new fibre optic sensor for chloride ion detection is reported. This sensor is based on the fluorescence quenching of an acridinium dye, which is covalently bound to polymer substrates, in presence of chloride ions. The active material is formed as a powder and packed in a tablet form. Calibration data shows that this fibre o...
