Formation of Composite Coatings on Galvanized Steel from Organosilane Solutions Using Electrophoresis and Sol-Gel Technology.

New hybrid composite coatings (HCCs) on hot-dip galvanized steel (HDGS) were obtained using electrophoresis (cathodic polarization (CP)) and sol-gel technology. For this purpose, a technique for the preparation of a cationic precursor based on TiCl and aminopropyltriethoxysilane was developed. Electrophoresis of the charged particles of the precursor and organosilanes promotes the production of denser sol-gel coatings with improved adhesion.

Epoxyorganosilane Finishing Compositions for Fibrous Fillers of Thermosetting and Thermoplastic Binders.

The development of universal finishing compositions for fibers of various natures is an urgent task for polymer composite materials science. The developed finishes can be used for the fiber reinforcement of polymer matrices with a wide range of surface free energy characteristics. Epoxy systems modified with diaminesilane in a wide concentration range were examined by optical interferometry, FTIR spectroscopy, DSC and the sessile drop technique.

Adsorption of Organosilanes on the Surface of Aluminium and the Formation of Organosilane Films to Protect It from Corrosion.

Adsorption of diaminesilane (DAS), vinyltrimethoxysilane (VS) on the surface of thermally precipitated aluminium was examined. The use of different adsorption isotherms made it possible to calculate the adsorption heats for DAS and VS. It was determined that chemisorption of these organosilanes occurred on the surface of aluminium.

[Thromboxane-prostacyclin balance and platelet aggregability in patients with minor cardiac abnormalities].

Aim: To reveal changes in the thromboxane-prostacyclin balance and platelet aggregability in patients with various variants of minor cardiac abnormalities.

Subjects And Methods: Six-five patients (mean age 23.0 +/- 0.

[Endothelium condition and platelet aggregation in patients with newly diagnosed type 1 diabetes mellitus and undifferentiated connective tissue dysplasia].

The study included 68 patients aged 18-32 years with newly diagnosed type 1 diabetes (DM) and/or undifferentiated connective tissue dysplasia (CTD). Ten healthy subjects without clinical symptoms of CTD served as controls. Induced platelet aggregation, Willebrand factor activity, plasma thromboxane B2, 6-keto-prostaglandin F1a, and endotheline-1 were measured.
