Investigation into the dispensing-based fabrication process for tissue scaffolds
… or replace damaged ones. In this field, tissue scaffold plays a key role to support cell growth and new tissue regeneration. For fabrication of tissue scaffolds with individual external geometry and predefined inner structure, rapid prototyping (RP) systems based on fluid dispensing techniques …

Preparation and Characterization of Electrospun rGO-Poly(ester amide) Tissue Engineering Scaffolds
Tissue engineering scaffolds should support tissue maturation through exposure to biologically relevant stimuli and through successful cell infiltration. External electrical stimulation is particularly relevant for cardiac and neural applications, and requires conductive scaffolds to propagate …

Tunability of Electrospun Scaffolds for Tissue Engineering
… a cheap and quick method of creating non-woven scaffolds for tissue regeneration and growth with the proper fiber diameter for cell adhesion. However, electrospun scaffolds lack large pores between fibers and result in a densely packed mesh in which cells can adhere only to the surface of the …

Three-dimensional virus scaffolds for energy storage and microdevice applications
… To synthesize 3-dimensional nanowire scaffolds, the M13 virus is covalently linked into a hydrogel that serves as a 3-dimensional bio-template for the mineralization of copper and nickel nanowires. Control of nanowire diameter, scaffold porosity, and film thickness is demonstrated. The …

Phase behaviour and structure formation of alginate-protein composite gels used in 3D bioprinting
… essential for cell attachment and enhancing scaffold porosity through temperature-sensitive dissolution. However, its animal origin raises ethical and sustainability concerns, particularly in bioprinting applications targeting the reduction of animal testing or cultured meat production. This …

The Influence of Structure and Surface Biochemistry on Cell Function and Angiogenesis in Collagen Scaffolds
… following implantation. Ice-templated collagen scaffolds have been used in tissue engineering due to their bioactivity, tunable biodegradability and the ability to produce architectures with tailored porosity, but until now very little work has focused on vascularisation of these structures. The …

Smart Quality Assurance System for Additive Manufacturing using Data-driven based Parameter-Signature-Quality Framework
… processes. This approach was applied to layer porosity quantification and quality assurance for polymer and hydrogel scaffold printing using an FFF process. 2. A data-driven surrogate model that can be informed using high-fidelity physical-based modeling was proposed to develop a …

Fabrication & Mechanical Properties of Hastelloy-X Matrix Ceramic Composite
… In this thesis, porous Hastelloy-X alloy scaffolds with 80% porosity, currently used for fabricating seals in turbine applications, were used as the base material. The microstructure of the porous Hastelloy-X scaffolds was infiltrated using a room temperature curing silicate colloid (trade …
