Impact of inactive dopants in chemical vapor deposition layers on photomodulated optical reflectance KU Leuven
The ITRS roadmap stresses the electrical characterization of the active doping profiles for sub-32 nm structures as a key challenge for future CMOS technology. Earlier work has shown the promising capabilities of non-destructive photomodulated optical reflectance (PMOR) techniques, based on the localized detection of variations in the reflectivity of the sample, due to thermal and plasma (excess carrier) effects as can be generated by a ...
Blood-brain barrier modelling of bioactive peptides Ghent University
Microbial Community Characterization in a Pilot-Scale Permeable Reactive Iron Barrier KU Leuven
A 2-year-old pilot-scale zerovalent iron (Fe-0)-permeable reactive barrier, treating groundwater contaminated with tetrachloroethylene and trichloroethylene, was microbially characterized using DNA-based polymerase chain reaction-DGGE (denaturing gradient gel electrophoresis) analysis. In situ mesocosm systems positioned in monitoring wells at different locations in the pilot-scale system allowed core sampling as a function of time without ...
Active Barrier Coating for Packaging Paper with Controlled Release of Sunflower Oils Hasselt University
The use of paper as a sustainable packaging material is favored, but it lacks sufficient barrier properties in terms of water repellence and oil resistance. Novel approaches consider active packaging materials or coatings with controlled release providing additional functionality for delivery of specific components to the surface. In this study, the development of a waterborne coating with organic nanoparticles and encapsulated sunflower oils is ...
Preparation of Amorphous Solid Dispersions by Cryomilling: Chemical and Physical Concerns Related to Active Pharmaceutical Ingredients and Carriers. Flanders Institute for Biotechnology KU Leuven
Quantitative 13C Solid-State NMR Spectra by Multiple-Contact Cross-polarization for Drug Delivery: From Active Principles to Excipients and Drug Carriers KU Leuven
In this contribution, we present an analysis of the main parameters influencing the efficiency of the (1)H → (13)C multiple-contact cross-polarization nuclear magnetic resonance (NMR) experiment in the context of solid pharmaceutical materials. Using the optimum experimental conditions, quantitative (13)C NMR spectra are then obtained for porous metal-organic frameworks (potential drug carriers) and for components present in drug formulations ...
Proteolytically active allergens cause barrier breakdown. Vrije Universiteit Brussel
Two major allergens--the house dust mite Dermatophagoides pteronyssinus (Der p 1) and cockroach allergens--are proteolytically active and stimulate the protease-activated receptor 2 (PAR-2). Jeong et al. (2008, this issue) exposed mouse and human epidermis to both allergens and correlated the observed delay in permeability barrier recovery to PAR-2 activation/signaling. This article exposes the secretive boundaries between barrier homeostasis ...
Predicting longevity of iron permeable reactive barriers using multiple iron deactivation models Ghent University University of Antwerp
Positive impact of microorganisms on the performance of laboratory-scale permeable reactive iron barriers KU Leuven
Degradation efficiencies of zerovalent iron (Fe0) containing different bacterial inocula, i.e., an iron(III)-reducing Geobacter sulfurreducens strain and/or a bacterial consortium, were compared to degradation efficiencies of noninoculated Fe0 in a laboratory-scale column experiment. Contaminant removal efficiencies and hydrogen production rates indicated an increasing reactivity in time for all inoculated iron columns, while reactivity of the ...
