Chiral Separations Using Polymeric Surfactants and Polyelectrolyte Multilayers in Open-Tubular Capillary Electrochromatography

Kapnissi‐Christodoulou, Constantina P.; Valle, B. C.; Warner, I. M. (2003)

In this study, fused-silica capillaries are modified using a polyelectrolyte multilayer (PEM) coating procedure in open-tubular capillary electrochromatography. The PEM coating was constructed in situ with alternating ...

Effects of monovalent anions of the Hofmeister series on DPPC lipid bilayers part I: Swelling and in-plane equations of state

Aroti, Andria; Leontidis, Epameinondas; Dubois, M.; Zemby, T. (2007)

Aiming to improve understanding of the mechanisms behind specific anion effects in biological systems we have studied the effects of sodium salts of simple monovalent anions belonging to the Hofmeister series on the bilayers ...

High nuclearity single-molecule magnets: A mixed-valence Mn26 cluster containing the di-2-pyridylketone diolate dianion

Stamatatos, Theocharis C.; Nastopoulos, Vassilios; Tasiopoulos, Anastasios J.; Moushi, Eleni E.; Wernsdorfer, W.; Christou, George; Perlepes, Spyros P. (2008)

The employment of the dianion (dpkd2-) of the gem-diol form of di-2-pyridylketone (dpk) as a tetradentate chelate in manganese chemistry is reported, and the synthesis, crystal structure, and magnetochemical characterization ...

Hofmeister anion effects on surfactant self-assembly and the formation of mesoporous solids

Leontidis, Epameinondas (2002)

Recent work on mesoporous silica formation using cationic and non-ionic templates has unveiled a large number of anion effects. Anions are seen to change the hydrolysis rates of the silicate precursors, affecting the surface ...

Molecular factors affecting the complex formation between deferiprone (L1) and Cu(II): Possible implications on efficacy and toxicity

Pashalidis, Ioannis; Kontoghiorghes, G. J. (2001)

Deferiprone (1,2-dimethyl-3-hydroxypyrid-4-one, L1, CAS 30652-11-0) is a new chelating drug used worldwide for the treatment of iron overloading conditions. Spectrophotometric and potentiometric measurements were carried ...

Monolayers, bilayers and micelles of zwitterionic lipids as model systems for the study of specific anion effects

Aroti, Andria; Leontidis, Epameinondas; Dubois, M.; Zemb, T.; Brezesinski, G. (2007)

This work is a review of the effect of different monovalent anions (belonging to the Hofmeister series) on a single model amphiphile, phosphatidylcholine molecules in contact with water, in three different geometries, ...

Oligoacetic acid characterization by isocratic and linear salt gradient anion-exchange chromatography

Li, H.; Patrickios, Costas S. (2001)

A homologous series of four oligomers of acetic acid (namely acetic acid, succinic acid, tricarballylic acid, and tetracarboxylic acid) is characterized using isocratic and linear salt gradient anion-exchange chromatography. ...

Study on single crystal structure of the antimony(III) bromide complex with 3-methyl-2-mercaptobenzothiazole and biological activity of some antimony(III) bromide complexes with thioamides

Ozturk, I. I.; Metsios, A. K.; Filimonova-Orlova, S.; Kourkoumelis, Nikolaos; Hadjikakou, Sotiris K.; Manos, Manolis J.; Tasiopoulos, Anastasios J.; Karkabounas, Spyridon Ch; Milaeva, E. R.; Hadjiliadis, Nick (2012)

Crystals of the [SbBr3(MMBZT)2] (1) complex (MMBZT = N-methyl-2- mercaptobenzothiazole) were grown from acetonitrile/methanol of the filtrate derived from the reaction between 3-methyl-2-mercaptobenzo thiazole (MMBZT) in ...

Use of chiral amino acid ester-based ionic liquids as chiral selectors in CE

Stavrou, Ioannis J.; Kapnissi‐Christodoulou, Constantina P. (2013)

In this study, the applicability of a chiral ionic liquid (CIL) as the sole chiral selector in CE was investigated for the first time. In particular, five amino acid ester-based CILs were synthesized and used as additives ...
