Paper Coatings Based on Polyvinyl Alcohol and Cellulose Nanocrystals Using Various Coating Techniques and Determination of Their Barrier Properties Hasselt University
The goal of this work was to improve the barrier properties of selected papers against water, grease and oil or gases (water vapor and oxygen) by covering them with biodegradable commercial coating carriers based on cellulose nanocrystals (CNCs) and polyvinyl alcohol (PVOH). The aim was also to obtain cellulose recyclable packaging materials with improved barrier characteristics. The properties of paper coatings based on CNCs and PVOH were ...
Biomimetic strategy towards gelatin coatings on PET. Effect of protocol on coating stability and cell-interactive properties Vrije Universiteit Brussel Ghent University
Gelatin-modified poly(ethylene terephthalate) (PET) surfaces have been previously realized via an intermediate dopamine coating procedure that resulted in surfaces with superior haemocompatibility compared to unfunctionalized PET. The present study addresses the biocompatibility assessment of these coated PET surfaces. In this context, the stability of the gelatin coating upon exposure to physiological conditions and its cell-interactive ...
Incorporation of fluorescent dyes in atmospheric pressure plasma coatings for in-line monitoring of coating homogeneity University of Antwerp
This paper reports on the incorporation of three commercial fluorescent dyes, i.e., rhodamine 6G, fluorescein, and fluorescent brightener 184, in plasma coatings, by utilizing a dielectric barrier discharge (DBD) reactor, and the subsequent monitoring of the coatings homogeneity based on the emitted fluorescent light. The plasma coatings are qualitatively characterized with fluorescence microscopy, UVvis spectroscopy and profilometry for the ...
Effect of hot coiling under accelerated cooling on development of non-equiaxed ferrite in low carbon steel Ghent University
Strengthening mechanisms dominant in non-equiaxed ferrite structures are not so familiar and well measured. In present study, non-equiaxed ferritic structures were generated and perceived to be strengthened by grain/crystal refinement, presence of varying substructures, solid solution strengthening, and textural hardening. A Nb-V microalloyed steel was modeled under various accelerated cooling and coiling temperature conditions in a ...
MODEL PREDICTIVE CONTROL OF SECONDARY COOLING MODES IN CONTINUOUS CASTING KU Leuven
© 2013 TANGER Ltd., Ostrava. The automatic control system of the continuous casting should help to more accurately maintain the prescribed temperature regime and thus produce a higher-quality of continuous-cast semifinished product. The paper is devoted to problems of development of the model predictive control (MPC) algorithms of the secondary cooling modes. Since the thermal physical parameters depend on the temperature of the cast metal and ...
