Active ion (NaCl) transport across isolated frog skin is discussed in relation to sodium and potassium composition and to O(2) consumption of skin. A distinction is made between processes in skin related to "unidirectional active ion transport" and processes related to "maintenance electrolyte equilibrium;" i.e., ionic composition of skin. Several metabolic inhibitors were found that could be u...

A new theory model based on the local composition concept (TNRF-modified NRTL (TNRF-mNRTL) model) was developed to express the short-range contribution of the excess Gibbs energy for the solutions containing polymer and electrolyte. An equation represented the activity coefficient of solvent was derived from the proposed excess Gibbs energy equation. The short-range contribution of interaction ...

Active ion (NaCl) transport across isolated frog skin is discussed in relation to sodium and potassium composition and to O3 consumption of skin. A distinction is made between processes in skin related to "unidirectional active ion transport" and processes related to "maintenance electrolyte equilibrium;" i.e., ionic composition of skin.

Dipicolinic acid was investigated as a new anchoring group for DSSCs. A pilot dye (PD2) bearing this new anchoring group was found to adsorb significantly stronger to TiO2 than its cyanoacrylic acid analogue. The electrolyte composition was found to have a strong effect on the photoelectrochemical properties of the adsorbed dye in the device, allowing the dye LUMO energy to be tuned by 0.5 eV. ...

a) Run the program HPCESIM. Copy all basic parameters (Equipment, Capillary, Buffer, Sample, Inject and Detect) for electrophoretic separation of mixture of 4 organic acids into table 1. Table 1 Voltage U (kV) Current I (μA) Thermostating temperature T (oC) Capillary length to detector L (mm) ID (inner diameter of capillary) (μm) Separation mode (anionic/cationic) Composition of basic electroly...

The relationships of potato (Solanum tuberosum L.) tuber membrane permeability and membrane lipid composition to sugar accumulation were examined. Tubers from four potato cultivars were stored for 40 weeks at 3 degrees C and 9 degrees C. Rates of tuber membrane electrolyte leakage, total fatty acid composition, free fatty acid composition, and sugar content were measured throughout the storage ...

The goal of dialysis for patients with chronic renal failure is to restore the composition of the body’s fluid environment toward normal. This is accomplished principally by formulating a dialysate whose constituent concentrations are set to approximate normal values in the body. Over time, by diffusional transfer along favorable concentration gradients, the concentrations of solutes that were ...

Infants and young children with acute gastroenteritis have been studied with regard to stool electrolyte composition, external electrolyte balance, and aldosterone excretion. At the height of fluid depletion the stool sodium concentrations are low (median 8 m-equiv/1, range 3-58 m-equiv/1). The results indicate that in gastroenteritis the colon is responding homeostatically to a state of second...

Electrochemical polymerization of aniline is one of the most promising methods to prepare polyaniline (PANI) materials. However, during this process, the electrolyte solution must be replaced after electropolymerization of a certain time because of the generation and the accumulation of the by-products, which have significant effects on the morphology, purity and properties of PANI products. Tr...

Using flawless components are important for a proper material selection and best working conditions to achieve the best performance of solid oxide fuel cells (SOFCs). Tape casting is the most used process for the fabrication of SOFC parts, especially anode and electrolyte due to its advantages regarding the other processes. In this study, the effect of slurry composition and milling time were s...
