Combined Mesoscale/Experimental Study of Selective Placement of Magnetic Nanoparticles in Diblock Copolymer Films via Solvent Vapor Annealing
(ACS Publications, 2016-03-16)
We present a combined theoretical/experimental study to investigate the effect of selective solvent vapor annealing treatment on the obtainment of highly ordered morphologies of symmetric poly(styrene-b-methyl methacrylate) ...
Liquefaction of Kraft Lignin at Atmospheric Pressure
(Tech Science Press, 2019)
[EN]Kraft lignin was liquefied using polyethylene glycol #400 (PEG) and
glycerol (G) in a weight ratio of 80/20 (w/w) and sulphuric acid (SA) as catalyst
under atmospheric pressure at 160ºC. The three independent variables: ...
Lignin-ester derivatives as novel thermoplastic materials
(RSC, 2016)
[EN] Spruce and eucalyptus lignins isolated by an organosolv process and lauroyl chloride were used as raw material for the synthesis of lignin-ester derivatives. The obtained products presented new and interesting properties ...
Multistage treatment of almonds waste biomass: characterization and assessment of the potential applications of raw material and products
(Elsevier, 2018-09-06)
Almond shells are waste biomass generated in agro-industrial activities, which represent a resource that can be further valorized upon treatment. The purpose of this work was to assess new value-added products obtained ...
Modification of Eucalyptus and Spruce organosolv lignins with fatty acids to use as filler in PLA
(2016-05-09)
Spruce (softwood) and Eucalyptus (hardwood) woods were used as raw material for lignin extraction by
organosolv process. Chemical, structural and thermal characterizations of the extracted lignin samples have
been performed ...
Nanostructuration of self-assembled poly(styrene-b-isoprene-b-styrene) block copolymer thin films in a highly oriented pyrolytic graphite substrate
(Elsevier, 2011-01-03)
Highly oriented pyrolitic graphite (HOPG) is a useful substrate to visualize epitaxial formation due to its crystallographic structure. The morphology of a poly(styrene-b-isoprene-b-styrene) block copolymer thin film on a ...
Controlled placement of polystyrene-grafted CdSe nanoparticles in self-assembled block copolymers
(Springer Nature, 2013)
Surface functionalization of semiconductor CdSe nanoparticles has been achieved with polystyrene (PS) brushes by “grafting from” technique for further addition to a polystyrene-b-polybutadiene-b-polystyrene (SBS) block ...
Magnetic nanocomposites based on poly(styrene-b-butadiene-b-methyl methacrylate) and modified Fe2O3 nanoparticles
(Elsevier, 2016-03-25)
In this work an ABC-type triblock copolymer has been used to prepare magnetic organic/inorganic nanocomposites by selectively placing maghemite nanoparticles modified on their surface with different polymer brushes. As ...
Lignin oxidation and depolymerisation in ionic liquids
(RSC, 2015-09)
The depolymerisation of lignin directly in the black liquor was studied, comparing two ionic liquids as extracting solvents (butylimidazolium hydrogen sulphate and triethylammonium hydrogen sulphate), under oxidising ...
Liquefaction of Kraft lignin using polyhydric alcohols and organic acids as catalysts for sustainable polyols production
(Elsevier, 2019)
[EN]In this work, three different organic acid catalysts, (acetic acid, lactic acid and citric acid), are proposed as an
alternative to common catalysts used in the liquefaction process of Kraft lignin. These organic acids ...
