Unexplored metallic cation effect in the acidity constants of p-t-butylthiacalix[4]arene, p-t-butylcalix[4]arene and p-t-butylcalix[6]arene in aqueous-organic media
(Taylor & Francis Ltd, 2017-12)
The influence of the metallic cation of the base (Li+, Na+ or K+) was determined on the acid–base constants of p-t-butylthiacalix[4]arene (TC4), p-t-butylcalix[4]arene (CA4) and p-t-butylcalix[6]arene (CA6) in ethanol/water ...
EVALUATION OF METAL TOXICITY BY A MODIFIED METHOD BASED ON THE FUNGUS GERRONEMA VIRIDILUCENS BIOLUMINESCENCE IN AGAR MEDIUM
(SETAC PRESS, 2010)
Metal cation toxicity to basidiomycete fungi is poorly understood, despite its well-known importance in terrestrial ecosystems. Moreover, there is no reported methodology for the routine evaluation of metal toxicity to ...
Alkyl chain length and metallic cation effects on the acid-base properties of C-alkylresorcin[4]arenes in aqueous media
(Elsevier Science, 2019-01)
The polyprotic behavior of C-alkylresorcin[4]arenes was investigated in aqueous media in a large interval of pH values by potentiometry and spectrophotometry. The pK a1 ; pK a2 ; pK a3 and pK a4 were determined. The pK ai ...
The use of cation exchange resins in wines: Effects on pH, tartrate stability, and metal content [El uso de resinas de intercambio catiónico en vinos: Efectos sobre el pH, la estabilidad tartárica, y el contenido de metales]

Role of monovalent and divalent metal cations in human ribokinase catalysis and regulation
(Springer, 2015)
Human ribokinase (RK) is a member of
the ribokinase family, and is the first enzyme responsible
for D-ribose metabolism, since D-ribose must first
be converted into D-ribose-5-phosphate to be further
metabolized and ...
The effect of metal-cation vacancies on vanadium antimonate surface properties. A theoretical study
(American Chemical Society, 2013-09-13)
In this work, we studied the distribution of V and Sb vacancies in the rutile-type vanadium antimonate phase and the influence of these cationic defects on the VSbO4(110) surface properties. We performed density functional ...
The use of cation exchange resins in wines: effects on ph, tartrate stability, and metal content
(2018)
Treating wines with cation exchange resins allows the reduction of pi I and contributes to limiting the formation of tartrate salts by exchanging cations such as potassium with hydrogen ions. This manuscript summarizes the ...
Effect of variations in annealing temperature and metallic cations on nanostructured molybdate thin films
(Springer, 2008-04-01)
Crystalline molybdate thin films were prepared by the complex polymerization method. The AMoO(4) (A = Ca, Sr, Ba) films were deposited onto Si wafers by the spinning technique. The Mo-O bond in the AMoO(4) structure was ...
