Introduction: Poly lactic co- glycolic acid (PLGA) and poly caprolacton (PCL) are highly applicable polymers in the field of drug delivery and tissue engineering scaffolds. Therefore, this study aimed to design an insulin-loaded PCL/PLGA hybrid nanofiber scaffold in order to be applied in attachment and growth of chondrocytes. Moreover, it can provide a vehicle for the controlled release of a...
Development of pore network models for real porous media requires a detailed understanding of physical processes occurring on the microscopic scale and a complete description of porous media morphology. In this study, the microstructure of porous media has been represented by three dimensional networks of interconnected pores and throats which are designed by an object oriented approach. Af...
In this study, NBG was successfully achieved through a sol-gel technique, and to further improve its dispersibility, a crylate coupling agent was coupled onto the surface of the NBG. The 3-(Trimethoxysilyl)Propylmethacrylate coupling agent was used to the surface modification of the synthesized NBG by a wet-chemical method in a dynamic inert nitrogen atmosphere. The surface properties of the bi...
The pore structure is an important feature of loess fabric and significantly influences the hydraulic properties. evolution during collapse has been extensively investigated but some aspects are still not well understood. In this study, 3D within same sample was characterized using X-ray micro-computed tomography in combination with in-house test set-up. space consists two distinct categories: ...
Porous phyllosilicate-based ceramics were manufactured by freeze-tape casting from clays of different particle size and morphology in order to characterize their microstructure stress rupture changes before after firing. Three raw selected: HCR (77% Halloysite–10Å), KORS (29% kaolinite), KCR kaolin (98% kaolinite). These exhibited a monomodal distribution used prepare four slurries, three with ...
Digital modeling of the microstructure is important for studying physical and transport properties porous media. Multiscale media can accurately characterize large-pores fine-pores in a large-FoV (field view) high-resolution three-dimensional pore structure model. This paper proposes multiscale reconstruction algorithm based on multiple dictionaries learning, which edge patterns fine-pore from ...
Ferromagnetic nanostructures have been electrodeposited within the pores of porous silicon templates with average pore diameters between 25 and 60 nm. In this diameter regime, the pore formation in general is accompanied by dendritic growth resulting in rough pore walls, which involves metal deposits also offering a branched structure. These side branches influence the magnetic properties of th...
