In coatings technology, the possibility of introducing specific characteristics at surface level allows for manufacture medical devices with efficient and prolonged antibacterial properties. This efficiency is often achieved by use a small amount molecules, which can fulfil their duty while limiting eventual releasing problems. The object this work was preparation characterization silver, titanium dioxide chitosan polyurethane-based coatings. Coatings three antibacterials were prepared using...
The polymerization of ethylene with late transition metal complexes typically provides highly branched amourphous poly(ethylene)s through a chain-walking mechanism, while the chain-straightening α-olefins gives semicrystalline polymers. Herein, we report 1-hexene, 1-octene, and 1-dodecene catalyzed by an α-diimine Ni(II) complex in combination diethylaluminum chloride. effect monomer chain length concentration on productivity, "livingness", selectivity insertion, polymer structure/properties...
With Brookhart type α-diimine Ni(II) based catalysts, it is highly challenging to tune polymers branching level and branch-type distribution, which in turn strongly affects thermal mechanical properties, through the aryl ortho-positions modification, while maintaining high turnover frequencies (TOFs). Herein, we are interested performing a systematic investigation on polymerization of 1-octene, 1-decene, 1-octadecene catalyzed by series nickel(II) complexes with methyl ligand backbone...
Bio-polyols from epoxidized soybean and linseed oils caprylic acid or 3-phenyl butyric were prepared using an environmentally friendly, solvent-free method evaluating the presence of triethylamine as catalyst. Side reactions, leading to a cross-linking structure with high density, reduced, introducing catalyst properly tuning reaction conditions. A medium functionality value around 3 along hydroxyl number up 90 mg KOH/g, narrow polydispersity index, relatively low molecular mass 2400 g/mol...
Abstract Anthropogenic climate change is warming sea water worldwide, pushing the limits of tolerance for marine organisms and driving a decline in biodiversity. The risk thermal anomalies has increased particularly Mediterranean region over last 30 yrs, where intense been identified as one main stressors coastal regions. To determine influence warmer conditions on immunity an endemic coral species, different immune activity parameters were compared response to elevated temperature (~ 28 °C)...
The new cobalt (II) phosphine complex CoCl2(PiPrPh2)2 was synthesized by reacting CoCl2 with isopropyldiphenylphosphine in ethyl alcohol as solvent. molecular structure of the determined X-ray diffraction method. then used combination methylaluminoxane for polymerization 1,3-butadiene: it found to be highly active and stereospecific preparation 1,2 syndiotactic polybutadiene. same system also able polymerize substituted butadienes giving stereoregular polymers from E-1,3-pentadiene,...
The challenge to manufacture medical devices with specific antibacterial functions, and the growing demand for systems able limit bacterial resistance growth, necessitates development of new technologies which can be easily produced at an industrial level. object this work was study silver, titanium dioxide, chitosan composites realization and/or implementation biomedical devices. Thermoplastic elastomeric polyurethane selected used as matrix various functions introduced during processing...

PLA spherulite growth rate overall isothermal crystallization rates decrease amount amorphous increase long period value in blend due to...
In this work, novel composites based on poly(ε-caprolactone) (PCL) were prepared and characterized in terms of morphological, thermal, rheological mechanical properties. Hollow glass microspheres (HGM), alone or surface modified by treatment with (3-aminopropyl)triethoxysilane (APTES) order to enhance the compatibility between inorganic particles polymer matrix, used obtain lightweight improved The silanization implies a good dispersion filler matrix an enhanced filler⁻polymer adhesion....
Propylene polymerizations with different ketimide-modified half-titanocene catalysts, Cp’TiCl2(N=CtBu2) [Cp’ = C5H5 (1), C5Me5 (2), Me3SiC5H4 (3)], MAO as a cocatalyst, were investigated. The obtained polymers studied in detail by determining their microstructure, molar masses, thermal, and mechanical properties. Cp*-ketimide, (C5Me5)TiCl2(N=CtBu2) exhibited higher catalytic activities than (1,3), yielding mass polymers, Mw up to 1400 Kg/mol. All the synthesized polypropylenes (PP) are...
