Design and manufacturing of customised maxillofacial prostheses.
(Elsevier, 2003-04-28)Customised implants created by Computer-Assisted Surgery (CAS) techniques and used in maxillofacial reconstruction indicate improved outcomes over conventional techniques. ‘‘Non-functional’’ multistaged procedures are ... -
Biomodels of bone: a review
(Springer, 2005)In this paper, a definition of a biomodel is presented, based on which different specific types of biomodels are identified, viz., virtual biomodels, computational biomodels, and physical biomodels. The paper then focuses ... -
Oxidation behaviour of particle reinforced MoSi2 composites at temperatures up to 1700 °C, Part I: Literature Review
(Wiley, 2005-02-04)In the first part of this paper the results of a literature review are presented. An overview of the oxidation behaviour in air and in combustion environments of both pure MoSi2 and MoSi2 composites in the temperature range ... -
Oxidation behaviour of particle reinforced MoSi2 composites at temperatures up to 1700°C. Part II: Initial screening of the oxidation behaviour of MoSi2 composites
(Wiley, 2005-03-01)In the first part of this paper a literature survey on the oxidation behaviour of MoSi2 and MoSi2 composites has been given. The present second part reports about the experimental results from oxidation tests with ... -
Oxidation behaviour of particle reinforced MoSi2 composites at temperatures up to 1700°C
(Wiley, 2005-04-04)The topic Oxidation behaviour of particle reinforced MoSi2 composites at temperatures up to 1700°C is discussed in a three part publication. In the first part of this paper a literature survey on the oxidation ... -
Electro-spinning of pure collagen nano-fibres – Just an expensive way to make gelatin?
(Elsevier, 2008-03-03)Scaffolds manufactured from biological materials promise better clinical functionality, providing that characteristic features are preserved. Collagen, a prominent biopolymer, is used extensively for tissue engineering ... -
Effect of hydroxyapatite on biodegradable scaffolds fabricated by SLS
(Trans Tech Publications Ltd., 2009)Selective laser sintering (SLS) has the potential to fabricate bioresorbable polymer / ceramic composite scaffolds with pre-designed external and internal architecture that can be used for bone tissue engineering applications. ... -
Investigation of the mechanical interaction of the trabecular core with an external shell using rapid prototype and finite element models
(Elsevier, 2009-04-05)The mechanical properties of vertebral bone have been widely studied with the ultimate goal of improving fracture risk prediction. However, the mechanical interaction between the cortical shell and the trabecular core is ... -
A combined experimental-numerical approach for generating statistically equivalent fibre distributions for high strength laminated composite materials
(Elsevier, 2009-11-04)A technique is presented where actual experimental distributions, measured from a high strength carbon fibre composite, are considered in the development of a novel method to generate statistically equivalent fibre ... -
Selective laser sintering of hydroxyapatite/poly-epsilon-caprolactone scaffolds
(2010)Selective laser sintering (SLS) enables the fabrication of complex geometries with the intricate and controllable internal architecture required in the field of tissue engineering. In this study hydroxyapatite and ... -
A method to fabricate small features on scaffolds for tissue engineering via selective laser sintering
(2010)Purpose:Selective laser sintering (SLS) is a rapid prototyping technique applied to produce tissue-engineering scaffolds from powder materials. The standard scanning technique, however, often produces struts of extensive ... -
Preferential cell response to anisotropic electro-spun fibrous scaffolds under tension-free conditions
(Springer, 2010-11)Anisotropic alignment of collagen fibres in musculoskeletal tissues is responsible for the resistance to mechanical loading, whilst in cornea is responsible for transparency. Herein, we evaluated the response of tenocytes, ... -
Recovery of cardiac function mediated by MSC and interleukin-10 plasmid functionalised scaffold
(2011-11)Stem cell transplantation has been suggested as a treatment for myocardial infarction, but clinical studies have yet to demonstrate conclusive, positive effects. This may be related to poor survival of the transplanted ... -
A Biomaterial Approach to Peripheral Nerve Regeneration: Bridging the Peripheral Nerve Gap and Enhancing Functional Recovery
(The Royal Society, 2011-11)Microsurgical techniques for the treatment of large peripheral nerve injuries (such as the gold standard autograft) and its main clinically approved alternative 'hollow nerve guidance conduits (NGCs)' have a number of ... -
Single Cyclized Molecule Structure from RAFT Homopolymerization of Multi-vinyl Monomers
(2012)We explore a kinetically controlled strategy to suppress the gelation in the homopolymerization of multi-vinyl monomers (MVMs) via RAFT polymerization. We report the generation of 3D single cyclized polymer structures from ... -
Osteogenic differentiation of mesenchymal stem cells is regulated by osteocyte and osteoblast cells in a simplified bone niche
(AO Research Institute Davos, 2012)Mesenchymal stem cells (MSCs) within their native environment of the stem cell niche in bone receive biochemical stimuli from surrounding cells. These stimuli likely influence how MSCs differentiate to become bone precursors. ... -
Stability enhancement of an atomic force microscope for long-term force measurement including cantilever modification for whole cell deformation
(2012)Atomic force microscopy (AFM) is widely used in the study of both morphology and mechanical properties of living cells under physiologically relevant conditions. However, quantitative experiments on timescales of minutes ... -
