Dispersion polymerization of methyl methacrylate in supercritical carbon dioxide: control of molecular weight distribution by adjusting particle surface area
Thierry Meyer, Charalampos Mantelis
Expts. of Me methacrylate dispersion polymn. are carried out in a reaction calorimeter using PDMS-mMA (methacrylate-terminated polydimethylsiloxane) as surfactant. Different stabilizer concns. from 0 to 10 wt% with respect to monomer have been considered i ...
2007Controlling polymer architecture in the thermal hyperbranched polymerization of L-lysine
Harm-Anton Klok, Markus Scholl
Because of the unequal reactivity of the two amine groups of L-lysine hydrochloride, thermal polymerization of this asymmetrical AB2 monomer results in hyperbranched polymers, which contain ?2.5 times more N?-linked linear compared to N?-linked linear stru ...
2007Si,C1-xO2 alloys: A possible route to stabilize carbon-based silica-like solids?
Novel extended tetrahedral forms Of CO2 have been synthesized recently under high-pressure conditions. We perform ab initio density functional theory calculations to investigate whether doping with Si can extend the stability range of such tetrahedral form ...
2007Analytical approximations for flow in compressible, saturated, one-dimensional porous media
A nonlinear model for single-phase fluid flow in slightly compressible porous media is presented and solved approximately. The model assumes state equations for density, porosity, viscosity and permeability that are exponential functions of the fluid (eith ...
2007Design of amphiphilic nanocapsules based on hyperbranched star-block copolymers for the encapsulation and the controlled release of olfactory compounds
Effective encapsulation of small, volatile, weakly water-soluble molecules such as flavors and fragrances is necessary to protect them from degradation, to increase their lifetime, and to improve their water dispersion and fixation depending on the substra ...
EPFL20072-Dimensional Porphyrin Self-Assemblies at Molecular Interfaces
Hubert Girault, Bin Su, Nicolas Eugster
The heterodimer formed by electrostatic association of zinc(II) meso-tetrakis(N-methylpyridyl)porphyrin (ZnTMPyP) and zinc(II) meso-tetrakis(p-sulfonatophenyl)porphyrin (ZnTPPS) exhibits a strong affinity for the interface between water and 1,2-dichloroeth ...
American Chemical Society2006Interaction of polyelectrolytes with oppositely charged surfaces
Despite progress during the last decade, the behavior of charged macromolecules, polyelectrolytes, including their interactions is not yet completely understood. In particular, interactions with oppositely charged surfaces, which play a significant role in ...
EPFL2005Adsorption de polycarboxylates et de lignosulfonates sur poudre modèle et ciments
Placing concrete requires much more water than the cement needs for its hydration. This results in an important porosity in the hardened concrete, which accentuates the degradation of this material. By adding small amounts of polymeric admixtures, called s ...

Jutta Christine Wandrey, Vesela Malinova
A family of cationic polyelectrolytes possessing defined chain lengths, narrow chain length distributions, uniform charge d., but substituents of different hydrophilicity at the quaternary ammonium group served as model compds. for adsorption studies. Thes ...
2004A molecular view of cholesterol-induced condensation in a lipid monolayer
We investigate the interrnolecular interactions in a mixed phospholipid/cholesterol monolayer using the surface-specific technique of vibrational sum frequency generation. This technique allows us to monitor the conformational and orientational order in th ...
