The acid-base properties of oxides are well described by the surface complexation model, which superposes a thermodynamic description of acid-base reactions at the oxide surface with a double-layer model of the electrostatics at the solid-solution interface. So far, however, this model has not been extended to include the effects of permanent charges such as result, for example, from isomorphic...

Supramolecular interaction is rapidly emerging as the method of choice for tuning molecular properties to meet desired applications like drug delivery vehicles, sensors, designing molecular architectures, catalysis chambers, biomimetic systems and so on. We have successfully demonstrated the modulation of electron and proton transfer reactions, acidbase characteristics and photophysical propert...

This study was created to investigate the effects of CO2 insufflationinduced pneumoperitoneum on indices of acidbase status and blood picture in dogs. Twelve adult male dogs were subjected to pneumoperitoneum after general anesthesia, pneumoperitoneum was induced throughout the 60 minutes and blood samples were collected at intervals, 0, 5, 15, 30 and 60 minutes. Results of statistical analysis...

Phosphazene polymers are classically synthesized by the ring-opening polymerization (ROP) of [PCl2N]3, followed by the functionalization of [PCl2N]n with desired side groups. Despite their versatile properties, phosphazene polymers are not widely used because of the inefficiency in the synthesis through the ROP process and difficulties in handling the [PCl2N]n. The overall goal of this research...

To the Editor:-The report by Scheingraber et al.’ highlights the phenomenon of acidemia after infusion of 0.9%) saline in the perioperative period. The accompanying editorial’ discusses several relevant points; however, we are disappointed that neither the article nor the editorial addresses the central issue of the relative merits of the Stewart approachg in describing acidbase physiology and ...

The differential diagnoses for acid-base problems can be reduced to a workable few by using a minimal amount of laboratory data. Following well-established principles and formulas, the presenter will help you resolve common acidbase problem cases. • Identify etiologies of anion gap and non-anion gap acidosis. • Explain the principle of osmolar gap. • Differentiate the causes of acid-base distur...

The separation technique of acidbase extraction was used to separate three unknown dye compounds that had different pH from the mixture. The identification of the unknown dyes compounds was performed based on the color of the dyes. Methyl Orange, a common dye, was synthesized and purified by recrystallization. The effectiveness of recrystallization was determined by calculating the percentage r...

Severe acid-base disorders combined with electrolyte disturbances are of ten seen in patients with hyperosmolar hyperglycaemic state (HHS) or diabetic ketoacidosis (DKA). Acid-base disorders and electrolyte disturbances are tightly connected [1]. The aims of this clinical lesson are (i) to give insight in the relation between hyperglycemia, acid-base disturbances and electrolyte homeostasis, (i...

FIFTEEN eyanotic patients with tetralogy of Fallot were studied at various times in the operating room and during the first 3 days after intracardiae repair of tetralogy of Fallot. Similar studies have not been reported previously. The accumulated data emphasize the need for precision in accomplishing the operation; allow description of the hemodynamic state, gas exchange, and acidbase profile ...

The emerging threat of ocean acidifi cation for marine life has re-emphasised the crucial importance of acidbase status and regulation in whole organism functional maintenance and enantiostasis. pH values in different body compartments are widely accepted to play a key role in the maintenance of physiological function or their limitation under functional or environmental stress. pH affects prot...
