Effect of different aqueous synthesis parameters on the size of CdSe nanocrystals
(Springer Nature, 2012-06-30)
The variation of CdSe nanoparticle size as a function of synthesis conditions is presented. Cadmium sulphate (CdSO4), cadmium chloride (CdCl2) and sodium selenosulphate (Na2SeSO3) solutions were used as precursors. ...
Kraft lignin as filler in PLA to improve ductility and thermal properties
(Elsevier, 2015-10)
[EN] Kraft lignin (KL) and acetylated Kraft lignin (AKL) were used as filler for the elaboration of composites
with poly(lactic acid) (PLA) in different concentrations (0.5, 1, 5, 10 and 20%) by extrusion method at
200 ...
Enhanced stability of photo-induced anisotropy due to intermolecular interactions in an azo-prepolymer confined in block copolymer
(Elsevier, 2013-02-08)
Many efforts in the field of azobenzene-containing polymers are concentrated on exploring new material concepts to obtain efficient and stable photo-induced anisotropy. Here, an easy approach to improve the birefringent ...
High-Performance Magnetic Activated Carbon from Solid Waste from Lignin Conversion Processes. 1. Their Use As Adsorbents for CO2
(ACS Publications, 2017-03-09)
[EN] Lignin is naturally abundant and a renewable precursor with the potential to be used in the production of both chemicals and materials. As many lignin conversion processes suffer from a significant production of solid ...
Hemicelluloses obtaining from rapeseed cake residue generated in the biodiesel production process
(2010-03-25)
[EN]The processing of rapeseed oil seeds for biodiesel production generates huge amounts of lignocellulosiccake residue mainly composed by cellulose, hemicelluloses and lignin. In this work, the valorisation ofthese ...
Thermocatalytic conversion of lignin in an ethanol/formic acid medium with NiMo catalysts: role of the metal and acid sites
(Elsevier, 2017-11-15)
[EN] NiMo catalysts supported on different sulfated and non-sulfated aluminas and zirconias were studied for the catalytic conversion of lignin in a formic acid/ethanol medium. All the pre-reduced NiMo-support combinations ...
Thermally-responsive biopolyurethanes from a biobased diisocyanate
(Elsevier, 2015-09)
In this work, segmented biopolyurethanes with thermally-activated shape-memory properties were synthesized and characterized. All the employed starting materials were derived from renewable sources. The macrodiol, which ...
Thin film nanocomposites based on SBM triblock copolymer and silver nanoparticles: morphological and dielectric analysis
(WILEY-VCH, 2017-07-20)
Hybrid organic/inorganic thin film nanocomposites based on poly(styrene)-b-poly(butadiene)-b-poly(methyl methacrylate) (SBM) triblock copolymer and silver nanoparticles (Ag) have been prepared and characterized. In order ...
Thermoplastic polyurethanes with glycolysate intermediates from polyurethane waste recycling.
(Elsevier, 2017-10)
The polyol is a major component in polyurethane formulations and therefore introducing to the formulation recycled polyol (obtained during decomposition process) allows decreasing the usage of pure petrochemical components. ...
Optimizing the extraction process of natural antioxidants from chardonnay grape marc using microwave-assisted extraction
(2019-03-21)
The aim of this work was to extract phenolic compounds from Chardonnay grape marc employing a
microwave-assisted extraction (MAE). Firstly, the effect of solvent concentration (30–60%), solid mass
(1.0–2.0 g) and extraction ...
