THE application of the quinhydrone electrode (or the quinoquinhydrone electrode or the hydroquinhydrone electrode) as substitute for the hydrogen electrode for the determination of PH is based on the fact that the values of the potentials between one of these electrodes and the hydrogen electrode vary but very little if the electrolytes of the two electrodes of the chain examined are identical....

Convenient reading out and/or determination of ionic strength (IS) is of great significance for both scientific research and real life applications. We presented here a novel method for the rapid and sensitive IS assay based on the electrolyte-induced sensitive wavelength blueshifts of the reflection spectra of polyacrylate capped Fe3O4 magnetic photonic crystals (PA-Fe3O4-MPCs). For HCl, MgSO4...

To evaluate the latent risk of acidosis in commercially available total parenteral nutrition (TPN) products, three types of commercially available TPN products were compared in postoperative patients. Sixty-four hospitalized patients with gastro-intestinal disease who undertook curative gastro intestinal resection were studied prospectively and administered with TPN solutions. Three types of co...

background: accurate working length determination is a pre-requisite for a successful endodontic treatment. even with improved systems of working length measurement, different readings may be recorded in different electrolytes present in the canal. the purpose of this in vivo/ex vivo comparative study was to determine the accuracy in measuring the working length of root canal using direct digit...

obtained here; and (3) the Soret coefficient u* obtained in TGTD experiments on electrolyte solutions differs from the Soret coefficient u obtained in nonelectrolyte mixtures as discussed at the end of section 3. These results agree in form with the results for nonelectrolytes.6 The important new features for electrolytes are (1) the present approach is considerably improved in simplicity and a...

In this study, two commercially available oral electrolyte solutions (OES) with high sodium (CF) or with high glucose and glycine (SL), and two prototype OES were evaluated in terms of rehydration and preventing catabolism. Prototype OES based on CF were prepared by doubling the glucose amount (CFG) or by doubling both glucose and glycine (CFGG). Thirty-two diarrheic calves were randomly assign...

We present a simulation method to study electrolyte solutions in a dielectric slab geometry using a modified 3D Ewald summation. The method is fast and easy to implement, allowing us to rapidly resum an infinite series of image charges. In the weak coupling limit, we also develop a mean-field theory which allows us to predict the ionic distribution between the dielectric charged plates. The agr...

The electric-double-layer structure in an electrolyte close to a solid substrate near the three-phase contact line is approximated by considering the linearized Poisson-Boltzmann equation in a wedge geometry. The mathematical approach complements the semianalytical solutions reported in the literature by providing easily available characteristic information on the double-layer structure. In par...
