Flocculation by Cationic Polyelectrolytes: Relating Efficiency with Polyelectrolyte Characteristics

A series of acrylamide/dimethylaminoethylacrylate methyl chloride copolymers (AM-co-DMAEA) was evaluated as flocculants for model Precipitated Calcium Carbonate (FCC) in distilled water. These cationic polyelectrolytes (PEL) differed by their AM/DMAEA rati ...

Fracture mechanisms in polystyrene/laponite nanocomposites prepared by emulsion polymerization

John Christopher Plummer, Riccardo Ruggerone

Transmission electron microscopy (TEM) has been used to investigate the effect of laponite clay on microdeformation in thin latex-based polystyrene (PS) films, in which the laponite was concentrated at the original interfaces between the PS particles. At r ...

Synthesis and characterization of novel polyelectrolytes based on double-charged cationic monomers

Ricardo Losada Mateo

Bis-1,3(N,N,N-trimethylammonium)-2-propylmethacrylate dichloride (di-M) and bis-1,3(N,N,N-trimethylammonium)-2-propylacrylate dichloride (di-A), two new double-charged monomers, were the subject of the research reported in this thesis. These monomers provi ...

Adsorption of superplasticizer admixtures on alkali-activated slag pastes

Paul Bowen, Yves Houst

Alkali-activatedslag(AAS) binders are obtained by a manufacturing process less energy-intensive than ordinary Portland cement (OPC) and involves lower greenhouse gasses emission. These alkaline cements allow the production of high mechanical strength and d ...

Copolymerization of a cationic double-charged monomer and electrochemical properties of the copolymers

Jutta Christine Wandrey, Ricardo Losada Mateo

The free radical copolymerization of 1,3-bis(N,N,N-trimethylammonium)-2-propylmethacrylate dichloride (di-M) with acryloyloxyethyltrimethylammonium chloride (Q), diallyldimethylammonium chloride (DADMAC), and acrylamide (A) yielded novel polyelectrolytes a ...

Local infiltration of planar photonic crystals with UV-curable polymers

Romuald Houdré, Libero Zuppiroli, Rolando Ferrini, Laurent Balet

We present the local polymer infiltration of planar photonic crystal cavities via a maskless laser-writing technique. After the infiltration of the air holes with a UV-curable monomer a focused laser is used to locally polymerize the monomer in selected ho ...

Radical homo-and copolymerization of acrylamide and ionic monomers in weak magnetic field

Jutta Christine Wandrey, Ignacio Rintoul

The synergy between magnetic ﬁeld (MF) and electrostatic interactions on the kinetics of radical homopolymerization of acrylamide (AM), acrylic acid (AA), its ionized form acrylate (A ...

The conformational flexibility of the carboxy terminal residues 105-114 is a key modulator of the catalytic activity and stability of macrophage migration inhibitory factor

Ursula Röthlisberger, Hilal Lashuel, Michele Cascella, Magdalena Zweckstetter, Hajer Ouertatani-Sakouhi, Farah El Turk

Macrophage migration inhibitory factor (MIF) is a multifunctional protein and a major mediator of innate immunity. Although X-ray crystallography revealed that MIF exists as a homotrimer, its oligomerization state in vivo and the factors governing its olig ...

Self-assembly of polypeptide/pi-conjugated polymer/polypeptide triblock copolymers in rod-rod-rod and coll-rod-coil conformations

Mohamad Hojeij, Raffaele Mezzenga

Self-assembly in the bulk of a series of hybrid triblock copolymers formed by a poly(9,9-dihexylfluorene-2,7-diyl) (PHF) middle block and two poly(gamma-benzyl-L-glutamate) (PBLG) end blocks has been studied. Since the alpha-helical secondary structure of ...
