We report the filling kinetics of different liquids in nanofabricated capillaries with rectangular cross-section by capillary force. Three sets of channels with different geometry were employed for the experiments. The smallest dimension of the channel cro ...
The heterodimer formed by electrostatic association of zinc(II) meso-tetrakis(N-methylpyridyl)porphyrin (ZnTMPyP) and zinc(II) meso-tetrakis(p-sulfonatophenyl)porphyrin (ZnTPPS) exhibits a strong affinity for the interface between water and 1,2-dichloroeth ...
A simple approach to sensor development based on encapsulating a probe molecule in a cellulose support followed by regeneration from an ionic liquid solution is demonstrated here by the codissolution of cellulose and 1-(2-pyridylazo)-2- naphthol in 1-butyl ...
The cyclic undecapeptide cyclosporin A (CsA) has a remarkable spectrum of diverse biological activities, including anti-inflammatory, antifungal, antiparasitic as well as immunosuppressive activities. However, the low water solubility of this drug is a ser ...
The gas phase methylation of biphenyl with MeOH over HZSM-5 and HZSM-5 modified with Si(OEt)4 was investigated at atm. pressure in the presence of water. The modification of the outer surface of the catalyst pellets by silicate gives increased selectivity ...
A linear water-sol. quaternary ammonium polymer having a homopolymeric chain of repeating unit I (R1 and R2 = linear or branched alkyl, hydroxyalkyl, alkoxyalkyl groups having 1-6 C atoms; X- = anion and n = 30-220) was prepd. The polymer has a molar mass ...

Superparamagnetic MnFe2O4 nanocrystals of different sizes were synthesized in high-boiling ether solvent and transferred into water using three different approaches. First, we applied a ligand exchange in order to form a water soluble polymer shell. Second ...
The sorption and desorption of poly(vinylpyrrolidone)-Se-0 (PVP-Se-0) nanoparticles on gel films of cellulose Acetobacter xylinum (CAX) are investigated. It is revealed that the hydrodynamic radius R (h) of PVP-Se-0 nanoparticles decreases from 57 nm in th ...
Regioselectivity control was studied in palladium catalyzed hydroxycarbonylation of styrene in neat water with water-sol. phosphines, mostly trisulfonated triphenylphosphine, TPPTS, but also N-bis(N',N'-diethyl-2-aminoethyl)-4-aminomethylphenyl-diphenylpho ...
Nanoparticles can be stabilized by an ionic liq. polymer (ILP) composed of imidazolium units incorporating a hydrophobic benzyl group. The resulting gold, platinum, and palladium nanoparticles can be efficiently transferred from water to ionic liqs. by exc ...
