Potentiometric Titrations as a Tool for Surface Charge Determination
This article summarizes methods for determining proton surface charge at mineral/water inter- faces. It covers conventional experimental procedures and discusses problems with the techniques. Also it
Raman spectra of aqueous solutions of strong electrolytes: evolving-factor analysis
Ion association in aqueous solutions of varied concentrations of LiNO3, Mg(NO3)2, Co(NO3)2, Li2SO4 and MgSO4 was studied by means of Raman spectrometry assisted by principal-components (PCA) and
Tetra­pyridinecopper(I) hexa­fluorido­phosphate(V)
The crystal structure of the title compound, [Cu(C5H5N)4]PF6, consists of discrete [Cu(C5H5N)4]+ and PF6− ions. Both the cations and the anions are located on \overline{4} axes. The pyridine ligands
Bis(amino acid) oxalyl amides as ambidextrous gelators of water and organic solvents: supramolecular gels with temperature dependent assembly/dissolution equilibrium.
Crystal structures of 2a and rac-5a show the presence of organisational motifs and intermolecular interactions in agreement with those in gel fibres elucidated by spectroscopic methods.
Acid–Base Properties and Kinetics of Hydrolysis of Aroylhydrazones Derived from Nicotinic Acid Hydrazide
AbstractA series of aroylhydrazones were synthesized from nicotinic acid hydrazide and differently substituted benzaldehydes. The protonation constants of the 12 resulting hydrazones, as well as of
4,9-Diazapyrenium cations. Synthesis, physico-chemical properties and binding of nucleotides in water
A series of new mono- and di-cationic 4,9-diazapyrenium derivatives were synthesized, for which in vitro anticancer activity has been demonstrated already and their spectroscopic properties and the influence of positive charges, aromatic surface and substituents on the formation of stacked complexes with major nucleotides in water and on their interaction with nucleic acids was investigated.
