Concentrations of free and total hydrogen ions, total protein and pepsin were measured in gastric juice fractions collected during basal secretion and upon stimulation by graded doses of pentagastrin administered intravenously. Undissociated hydrogen ion and non-pepsin protein concentrations were calculated as derived quantities. The studies were carried out in nine patients with duodenal ulcer...

In the title compound, (C(12)H(24)N)[Sn(CH(3))(3)(C(6)H(6)O(3)P)(2)], the SnMe(3) residues are axially coordinated by two monodentate [PhPO(3)H](-) anions, leading to a trigonal-bipyramidal geometry for the Sn(IV) atom. The two [SnMe(3)(PhPO(3)H)(2)](-) anions in the unit cell are associated into infinite chains along the a axis by O-H⋯O hydrogen bonds involving the hy-droxy group of the hydrog...

Carbon nanotubes CNTs inevitably contain defects that exert a significant influence on their physical, electrical, and electrochemical properties. In this study, we subject vertically aligned multiwalled CNT ensembles to argon and hydrogen ion irradiation, to artificially introduce defects into the structure. Subsequently, Raman spectroscopy in conjunction with electrochemical analyses was used...
