Preparation and Characterization of Polyphenylsulfone (PPSU) Membranes for Biogas Upgrading KU Leuven
Asymmetric polyphenylsulfone (PPSU) membranes were fabricated by a non-solvent induced phase inversion method. Glycerin and silica nanoparticles were added into the polymer solution to investigate their effects on the material properties and gas separation performance of prepared membranes. The morphology and structure of PPSU membranes were analyzed by scanning electron microscopy (SEM), the surface roughness of the selective layer was analyzed ...
Truncation of CXCL8 to CXCL8(9-77) enhances actin polymerization and in vivo migration of neutrophils KU Leuven
CXCL8 is the principal human neutrophil-attracting chemokine and a major mediator of inflammation. The chemokine exerts its neutrophil-chemotactic and neutrophil-activating activities via interaction with glycosaminoglycans (GAGs) and activation of the G protein-coupled receptors (GPCRs) CXCR1 and CXCR2. Natural CXCL8 displays an exceptional degree of amino (NH2 )-terminal heterogeneity. Most CXCL8 forms result from proteolytic processing of ...
Capillary Break-up of Complex Fluids: A Road Towards Better Understanding KU Leuven
The present PhD thesis focusses on exploring current open-ended issues in capillary break-up rheometry. Exploiting the natural phenomenon of capillarity instability, capillary break-up rheometry represents a very powerful technique to extract material information in free-surface, uniaxial extensional flows, which are of the utmost importance in understanding and controlling processes and applications involving the formation of liquid ligaments, ...
Preparation of patterned flat-sheet membranes using a modified phase inversion process and advanced casting knife construction techniques KU Leuven
High fluxes and low fouling are practically highly desired in all membrane processes. One generic way to realize this is by introducing surface patterns on the membrane to increase the active area and the surface roughness. A new method to prepare flat-sheet patterned membranes using a patterned knife combined with a modified phase inversion process is now presented. After casting the polymer solution, the patterned knife shapes the top surface ...
Mechanical behavior of basalt and glass textile composites at high strain rates : a comparison Universiteit Gent
The aim of this paper is to study and compare the mechanical behavior of woven basalt and woven glass epoxy composites at high strain rates, in order to assess the possibility of replacing glass fiber composites with basalt fiber composites for aircraft secondary structures, such as radomes, fairings, wing tips, etc. Both composites were produced using the same epoxy matrix, the same manufacturing technique, and with comparable densities, fiber ...
Nanocomposites of poly(hydroxyurethane)s with multiwalled carbon nanotubes Universiteit Antwerpen
Poly(hydroxyurethane)s (PHUs) are synthesized via non-isocyanate approaches and could be the potential alternatives of conventional polyurethanes. It is of importance to investigate the structure–property relationship of PHUs. In this work, we investigated the PHU nanocomposites containing multiwalled carbon nanotubes (CNTs). First, CNTs were functionalized with poly(acryloyl carbonate), a polymer bearing 6-membered cyclic carbonate groups ...
Non-steady scaling model for the kinetics of the photo-induced free radical polymerization of crosslinking networks Universiteit Gent
The competition of termination and shielding to evaluate the success of surface-initiated reversible deactivation radical polymerization Universiteit Gent
Thioacetate-based initiators for the synthesis of thiol-end-functionalized poly(2-oxazoline)s Universiteit Gent
New functional initiators for the cationic ring-opening polymerization of 2-alkyl-2-oxazolines are described to introduce a thiol moiety at the alpha terminus. Both tosylate and nosylate initiators carrying a thioacetate group are obtained in multigram scale, from commercial reagents in two steps, including a phototriggered thiol-ene radical addition. The nosylate derivative gives access to a satisfying control over the cationic ring-opening ...
