Liposomes as carriers of antimicrobial drugs
(Taylor & Francis Ltd, Abingdon, 1997)
Liposome are promising drug carrier systems being developed. Their successful use in the treatment of several diseases demonstrates that a solid rationale for clinical development of liposomes as antimicrobial drug carriers ...
Polymeric and immobilized crown compounds, material for ion separation
(Pergamon-Elsevier Science Ltd, Oxford, 1997)
We describe the synthesis of ionoselective polymers bearing different pendant crown ethers. The synthesis was applied to various macrocycles. We discuss the influence of macrocyclic cavity Size and rigidity of the polymers ...
Graphic simulation of STM images of Si(111)7X7 surface
(Trans Tech Publications Ltd., 1997)
The posibilities of graphic STM image simulation at atomic level are indicated. The presented procedure takes into account various types of deformation on the surface near the Fermi level. A clean Si(111)7X7 surface is ...
The thermal degradation of some alkali metal salts of poly(itaconic acid)
(Springer, Dordrecht, 1997)
The Li-, Na- and K salts of poly(itaconic acid) (PIA) were prepared by treating the polyacid with the corresponding aqueous hydroxide. The resulting polysalts were analysed by elemental analysis, FTIR spectroscopy and ...
Surface electrochemistry of CO on Pt(110)-(1x2) and Pt(110)-(1x1) surfaces
(Elsevier Science Bv, Amsterdam, 1997)
A new type of flame-annealing method has been developed for the preparation of surfaces having either fcc(110)-(1x1) or fcc(110)-(1 x 2) symmetry. In situ X-ray scattering studies show that both the Pt(110)-(1 x 2) and ...
Electrooxidation of H-2/CO mixtures on a well-characterized Pt75Mo25 alloy surface
(Amer Chemical Soc, Washington, 1997)
The electrochemical oxidation of hydrogen in the presence of carbon monoxide (0.05-2%) on a well-characterized Pt75Mo25 alloy surface was examined using the rotating disk electrode technique in 0.5 M H2SO4 at 333 K. The ...
Analysis of mass transfer in beer diafiltration with cellulose-based and polysulfone membranes
(Elsevier, Amsterdam, 1997)
An experimental investigation of beer dialysis with transmembrane pressure (diafiltration) was performed using two different hollow-fibre membranes: cuprophane (regenerated cellulose) and polysulfone for different flow ...
Relationship between fracture resistance and critical temperature difference in ceramic materials
(Plenum Publ Corp, New York, 1997)
The resistance of ceramics to thermal shock can be characterized using either a parameter of their resistance to fracture R or the critical temperature difference Delta T-c = Delta T-c (Bi). It is demonstrated that a ...
Temperature-dependent hydrogen electrochemistry on platinum low-index single-crystal surfaces in acid solutions
(Amer Chemical Soc, Washington, 1997)
The hydrogen evolution (HER) and the hydrogen oxidation reaction (HOR) were studied on platinum single crystals in a sulfuric acid solution over the temperature range 274-333 K. We found, for the first rime, that at a fixed ...
Thermogravimetric characterisation of poly(methyl methacrylate) photopolymerised by colloidal cadmium sulphide
(Springer, Dordrecht, 1997)
The thermal stability of poly(methyl methacrylate) (PMMA) photopolymerised using colloidal cadmium sulphide as the photoinitiator was studied by thermogravimetry (TG) and differential TG (DTG). The thermal stability of the ...
