Nanofibrous gelatin scaffolds were prepared by electrospinning from aqueous acetic acid and cross-linked thermally by glucose. The effect of the amount of glucose used as cross-linking agent on the mechanical properties of gelatin fibres was studied in this paper. The elastic modulus of gelatin fibres cross-linked by glucose was determined by modelling the behaviour of the meshes during tensile test. The model draws connections between the elastic moduli of a fibrous mesh and the fibre material and allows evaluation of elastic modulus of the fibre material. It was found that cross-linking by glucose increases the elastic modulus of gelatin fibres from 0.3 GPa at 0 % glucose content to 1.1 GPa at 15 % glucose content. This makes fibrous gelatin scaffolds cross-linked by glucose a promising material for biomedical applications.
The secondary reaction of HCl with the growing metal oxide surface during atomic layer deposition from a metal chloride and water is investigated using model calculations. HCl released during chemisorption of a metal chloride occupies adsorption sites for the metal chloride which results in a decrease in the film thickness in the gas-flow direction. The calculation model based on the continuity equation and kinetic equations for the surface coverage is described. The dependences of the thickness profile on the reactivity of HCl and on the adsorption of the metal chloride are analysed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
