Pertraction of phenol in hollow-fiber membrane contactors
(Elsevier, Amsterdam, 2004)
In this paper the multistage membrane pertraction (simultaneous extraction and reextraction) of phenol with linear monoalkyl cyclohexane (IMACH) as a carrier and sodium hydroxide solution as a strip, in laboratory scaled ...
Dynamical mechanical analysis of photocrosslinked hyperbranched urethane acrylates
(Srpsko hemijsko društvo, Beograd, 2004)
A series of acrylate functionalized samples based on hyperbranched hydroxy-terminated polyesters with different molecular weights and different degrees of acrylation were synthesized. The obtained urethane acrylates were ...
Preparation and properties of polymeric and composite bioresorbable barrier membranes
(Trans Tech Publications Ltd, Durnten-Zurich, 2004)
Bioresorbable barrier membranes have been widely used in dentistry and maxillofacial surgery. When the membranes are placed over bony defects and are closely adapted by the surrounding bone face, an environment that prevents ...
Electrophoretic deposition of boehmite coatings on titanium from aqueous sols
(Trans Tech Publications Ltd, Durnten-Zurich, 2004)
The electrophoretic deposition from sots and colloidal suspensions of ceramic powders has many advantages over conventional ceramic powder processing methods. In this way it is possible to control the thickness and ...
