Making the insoluble soluble : PEtOx based amorphous solid dispersions with high drug loadings using solvent electrospinning as a formulation technique Ghent University
Een leven zonder geneesmiddelen lijkt onmogelijk, ze zijn alomtegenwoordig. Naarmate de wetenschap haar grenzen blijft verleggen, heeft ook de zoektocht naar geneesmiddelen zich sterk ontwikkeld. Echter, dit gerichte geneesmiddelenontwerp heeft een keerzijde: er wordt veel minder aandacht besteed aan eigenschappen zoals de waterige oplosbaarheid van de actieve component. Als gevolg daarvan heeft meer dan 90% van de geneesmiddelen in ontwikkeling ...
Electrospinning and functionalization of silicon oxide nanofibers via sol-gel technology Ghent University
Fiber diameter control in electrospinning KU Leuven
© 2014 AIP Publishing LLC. A simple model is proposed to predict the fiber diameter in electrospinning. We show that the terminal diameter is determined by the kinetics of the jet elongation - under the influence of the electric and viscous forces - and the solvent evaporation. Numerical and simple scaling analyses are performed, predicting the fiber diameter to scale as a power 1/3 of viscosity and 2/3 of polymer solution throughput divided by ...
Electrospinning: the road to a new class of materials? Ghent University
Copper electrowinning from complex electrolytes Ghent University
Stainless steel substrate pretreatment effects on copper nucleation and stripping during copper electrowinning Ghent University
The effects of surface pretreatment of 304 stainless steel (SS) substrates on copper film formation, adhesion, and purity obtained by galvanostatic electrodeposition at a current density of - 30 mA cm(-2) are presented. The polished substrate produced more copper nuclei, resulting in an increase of the adhesion as compared to chemically oxidized SS substrate. The adhesion of the copper deposits was characterized by a Nano-scratch tester (NST). ...
Arsenic codeposition during the initial phases of copper nucleation and growth on stainless steel in normal electrowinning conditions Ghent University
Arsenic (As), bismuth (Bi) and antimony (Sb) are known to affect the quality of copper deposits in copper electrowinning operations. The codeposition of As was previously believed to occur only at current densities far exceeding the range of typical current densities for copper electrowinning. In this study, we investigate the copper electrodeposition on different pretreated stainless steel (SS) substrates from bleed electrolyte in galvanostatic ...
