Melt Rheology of Aliphatic Hyperbranched Polyesters
(Wiley, 2009)
Rheological behavior in melt of aliphatic hyperbranched polyesters (AHBP), synthesized using pseudo-one-step and one-step procedure, was investigated in this work. Three commercially available AHBP were also examined. ...
Preparation and properties of polymeric and composite bioresorbable barrier membranes
(Progress in Advanced Materials and Processes, 5th Conference of the Yugoslav-Materials-Research-Society (Yu-MRS 2003), Sep 15-19, 2003, Herceg Novi, Yugoslavia, 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 ...
Contribution of marine and continental aerosols to the content of major ions in the precipitation of the central Mediterranean
(Elsevier, 2006)
The region of the investigated receptor is situated in the southern part of the Adriatic Sea in the Mediterranean. The measuring station is located on the seashore, which, being considered as a border area, is representative ...
Interaction of Mg enriched kaolinite-bentonite ceramics with arsenic aqueous solutions
(Elsevier, 2009)
Mg-enriched kaolinite–bentonite ceramics prepared in this work exhibited very porous and non-uniform structures, with grain sizes ranging from 1 to 20 μm. During the interaction of this ceramics with aqueous solutions of ...
Textural and fractal properties of CuO/Al 2 O 3 catalyst supports
(Elsevier, 2006)
Reactive amorphous aluminas with a high surface area, suitable as a precursor for catalyst supports, are obtained by flash calcination of gibbsite in a reactor for pneumatic transport in the dilute two phase flow regime. ...
Syntheses of Tetrahydro-β-Carbolines via Tandem Hydformylation / Pictet-Spengler Reaction, Scope and limitations
(Royal Society of Chemistry, 2008)
A novel one-pot synthesis of tetrahydro-β-carboline systems via tandem hydroformylation–Pictet–Spengler reaction starting from olefins and aryl ethylamines is described. This tandem procedure allows fast and convenient ...
Lasers Interactions, Influence and Applications in Textile Industry
(Virginia (SAD): Mc Lean, 2001)
Some of the materials from textile industry or prepared in laboratory conditions were exposed to laser beams. The microscopic changes were considered in order to help selecting the optimal conditions for laser scanning of ...
Application of Iridium Catalized Allylic Substitution Reactions in the Synthesis of Branched Triptamines and Homologues via Tandem Hydroformylation/Fischer Indole Synthesis
(Royal Society of Chemistry, 2008)
Combination of enantioselective allylation reactions with a tandem hydroformylation–Fischer indole synthesis sequence as a highly diversity-oriented strategy for the synthesis of tryptamines and homologues was explored. ...
The effect of the structure of mixed tetraoxanes on their chromatographic behavior on different adsorbents
(Research Inst Medicinal Plants, Budakalasz, 2004)
The retention behavior of 29 biologically active compounds, mixed 1,2,4,5-tetraoxanes, has been investigated by thin-layer chromatography on unmodified silica, CN-silica, and RP-18-silica. The binary mobile phases ethyl ...
Synthesis, characterization and cytotoxicity of surface amino-functionalized water-dispersible multi-walled carbon nanotubes
(Elsevier, 2009)
Surface functionalization of multi-walled carbon nanotubes (MWCNTs), with amino groups via chemical modification of carboxyl groups introduced on the nanotube surface, using O-(7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium ...
