Complete capillary electrophoresis process on a drone: towards a flying micro-lab.
Drevinskas T, Maruška A, Girdauskas V, Dūda G, Gorbatsova J, Kaljurand M. Drevinskas T, et al. Among authors: kaljurand m. Anal Methods. 2020 Nov 7;12(41):4977-4986. doi: 10.1039/d0ay01220c. Epub 2020 Oct 2. Anal Methods. 2020. PMID: 33006341
In this work, we demonstrated sampling and separation of volatile amines (triethylamine and diethylamine) and organic acids (acetic and formic acids), non-volatile inorganic cations (K(+), Ca(2+), Na(+)), and protein (bovine serum albumin) in the aerosol state. ...

Superbasicity of a bis-guanidino compound with a flexible linker: a theoretical and experimental study.
Coles MP, Aragón-Sáez PJ, Oakley SH, Hitchcock PB, Davidson MG, Maksić ZB, Vianello R, Leito I, Kaljurand I, Apperley DC. Coles MP, et al. Among authors: kaljurand i. J Am Chem Soc. 2009 Nov 25;131(46):16858-68. doi: 10.1021/ja906618g. J Am Chem Soc. 2009. PMID: 19874017
X-ray diffraction data have been recorded over the temperature range 50-273 K. Examination of the carbon-nitrogen bond lengths suggests a degree of "partial protonation" of the neutral guanidino group at higher temperatures, with greater localization of the proton at one n …

Characterization of the antioxidative activity of novel nontoxic neuropeptides by using capillary electrophoresis.
Vaher M, Viirlaid S, Ehrlich K, Mahlapuu R, Jarvet J, Soomets U, Kaljurand M. Vaher M, et al. Among authors: kaljurand m. Electrophoresis. 2006 Jul;27(13):2582-9. doi: 10.1002/elps.200500760. Electrophoresis. 2006. PMID: 16732619
The second-order rate constants were similar for all peptides if the oxidation was carried out with hydrogen peroxide (k(II) = 0.208 - 0.236 x 10(3)/M.min). The rate constants were also determined for the mixtures of peptides. When the oxidation is caused by hydroxyl radic …

Gas-phase lithium cation basicity: revisiting the high basicity range by experiment and theory.
Mayeux C, Burk P, Gal JF, Kaljurand I, Koppel I, Leito I, Sikk L. Mayeux C, et al. Among authors: kaljurand i. J Am Soc Mass Spectrom. 2014 Nov;25(11):1962-73. doi: 10.1007/s13361-014-0970-4. Epub 2014 Sep 5. J Am Soc Mass Spectrom. 2014. PMID: 25190215
According to high level calculations, the upper part of the previously published FT-ICR lithium cation basicity (LiCB at 373 K) scale appeared to be biased by a systematic downward shift. The purpose of this work was to determine the source of this systematic difference. N …
