Quantitative aspects of electrolysis in electromembrane extractions of acidic and basic analytes.

Analytica chimica acta

Šlampová A, Kubáň P, Boček P.
PMID: 26320790
Anal Chim Acta. 2015 Aug 05;887:92-100. doi: 10.1016/j.aca.2015.06.040. Epub 2015 Aug 07.

Electrolysis is omnipresent in all electrochemical processes including electromembrane extraction (EME). The effects of electrolysis on quantitative aspects of EME were comprehensively evaluated for a set of acidic (substituted phenols) and basic (basic drugs) analytes. EMEs were carried out...

Comprehensive study of buffer systems and local pH effects in electromembrane extraction.

Analytica chimica acta

Restan MS, Jensen H, Shen X, Huang C, Martinsen ØG, Kubáň P, Gjelstad A, Pedersen-Bjergaard S.
PMID: 28843554
Anal Chim Acta. 2017 Sep 01;984:116-123. doi: 10.1016/j.aca.2017.06.049. Epub 2017 Jun 30.

Different phosphate-, acetate- and formate buffers in the pH range 2.0-6.8 were tested for electromembrane extraction (EME) in a 96-well system. The five basic drugs haloperidol, loperamide, methadone, nortriptyline, and pethidine were selected as model analytes. The EME performance...

Multimode supercontinuum generation in chalcogenide glass fibres.

Optics express

Kubat I, Bang O.
PMID: 26906826
Opt Express. 2016 Feb 08;24(3):2513-26. doi: 10.1364/OE.24.002513.

Mid-infrared supercontinuum generation is considered in chalcogenide fibres when taking into account both polarisations and the necessary higher order modes. In particular we focus on high pulse energy supercontinuum generation with long pump pulses. The modeling indicates that when...

Ion-chromatographic separation of metal cations in the presence of alpha-hydroxyisobutyric acid.

Analytical and bioanalytical chemistry

Janos P, Chromá H, Kubán V.
PMID: 15045436
Anal Bioanal Chem. 1996 May;355(2):135-40. doi: 10.1007/s0021663550135.

Separations of metal cations on a column packed with the strongly acidic cation exchanger Separon SGX CX were investigated in the presence of alpha-hydroxyisobutyric acid (HIBA) in the mobile phase. A retention model based on the general theory of...

IEEE transactions on ultrasonics, ferroelectrics, and frequency control

Kubat F, Ruile W, Hesjedal T, Stotz J, Rösler U, Reindl LM.
PMID: 15600088
IEEE Trans Ultrason Ferroelectr Freq Control. 2004 Nov;51(11):1437-48. doi: 10.1109/tuffc.2004.1367484.

High power applications of Surface Acoustic Wave (SAW) devices may lead to acoustomigration in their thin metal electrodes, which deteriorates the performance or may even destroy the SAW device. It is confirmed in this paper that the mechanism of...
