The acid-base equilibrium in acid (phenylphosphonic acid, methylsulfonic acid, phosphoric acid, hydrochloric acid, acetic acid, and sulfuric acid)-benzimidazole (BIm) complexes was studied by (1)H NMR spectra, FTIR spectra, and density functional theory (

We applied interface-selective heterodyne-detected electronic sum frequency generation (HD-ESFG) to the pH spectrometry of an air/cationic surfactant/water interface in order to obtain insight into an acid−base equilibrium at the interface.

Acid–base equilibrium of puerarin in CTAB micelles
Journal of Pharmaceutical and Biomedical Analysis, 2007Electronic absorption spectra, fluorescence emission spectra, 1HNMR and ab initio quantum calculation are used to study the acid-base equilibrium of puerarin in cetytrimethylammonium bromide (CTAB) micelles with different microstructures and microenvironments.

This Microreview focuses on the recently developed hydrogenation of CO2 and hydrogen carbonate catalyzed by half-sandwich complexes with 4,4′-dihydroxy-2,2′-bipyridine (dhbp) and 4,7-dihydroxy-1,10-phenanthroline (dhpt).

Acid-Base Equilibrium in Chronic Hypercapnia
1974Patients with chronic respiratory acidosis are not immune to other disorders of acid-base equilibrium. As a consequence, the physician often faces a diagnostic dilemma: What in the acid-base pattern of such a patient should be attributed to hypercapnia and what is a reflection of complicating acid-base disturbances?

Regulation of Intracellular Acid‐Base Equilibrium in Rats
Acta Anaesthesiologica Scandinavica, 1983The extracellular pH (pHe) of unrestrained male Sprague‐Dawley rats was altered by either inhalation of CO2 or infusion of sodium bicarbonate and then kept constant for at least 2 h. The intracellular pH (pHi) was then determined by the DMO (5,5‐dimethyl‐2,4‐oxazolidinedione)‐method in heart, brain, liver, spleen, and ten different skeletal muscle ...

Oscillations of acid-base equilibrium during maximum exercise
Internationale Zeitschrift f�r Angewandte Physiologie Einschliesslich Arbeitsphysiologie, 1968Respiratory oscillations of alveolar CO2 tension have been studied during maximum exercise, using (I) a computer simulated nine-slice model of the lungs, (II) a rapid response infra-red gas analyser sampling at the mouth, and (III) measurements of the CO2 tension of arterialized capillary blood by the Astrup apparatus.
