Mirzaali, Mohammad J. (author), Shahriari, N.S. (author), Zhou, J. (author), Zadpoor, A.A. (author)Additive manufacturing (AM) technologies, particularly those based on powder bed fusion (PBF), most notably, selective laser melting (SLM) for metals, have in recent years emerged as unique fabrication methods for patient-specific implants made of metals and their alloys. The ability to manufacture complex geometries together with the other...book chapter 2023

(author), Leeuwenburgh, S.C.G. (author), Weinans, H. (author)Porous titanium scaffolds are a promising class of biomaterials for grafting large bone defects, because titanium provides sufficient mechanical support, whereas its porous structure allows bone ingrowth resulting in good osseointegration. To reinforce porous titanium scaffolds with biological cues that enhance and continue bone regeneration,...journal article 2013

Zadpoor, A.A. (author)The relationship between hip deformities and osteoarthritis has recently received a lot of attention. In particular, it has been shown that both osteoarthritis and its precursors, such as the hip deformities that lead to femoroacetabular impingement (FAI), are more prevalent in elite athletes compared with the general population. However, the...journal article 2015

Janbaz, S. (author), Weinans, H. (author), Zadpoor, A.A. (author)Recent research has shown the potential of rationally designed geometrical features for controlling the functionality of advanced materials. Of particular recent interest has been the use of geometry for controlling the buckling behaviour of soft materials under compression. However, the effects of geometry may be mixed with those of the...journal article 2016

(author), Zadpoor, A.A. (author), Weinans, H.H. (author), Jahr, H. (author)Regeneration of load-bearing segmental bone defects is a major challenge in trauma and orthopaedic surgery. The ideal bone graft substitute is a biomaterial that provides immediate mechanical stability, while stimulating bone regeneration to completely bridge defects over a short period. Therefore, selective laser melted porous titanium,...journal article 2015

Zadpoor, A.A. (author), Sinke, J. (author), Benedictus, R. (author)This article studies the properties of a wide range of friction-stir-welded joints with dissimilar aluminum alloys or thicknesses. Two aluminum alloys, namely, 2024-T3 and 7075-T6, are selected for the study and are welded in ten different combinations of alloys and thicknesses. The welding parameters are optimized for each configuration, and a...journal article 2010

(author)It is known that the mechanical properties of bone-mimicking porous biomaterials are a function of the morphological properties of the porous structure, including the configuration and size of the repeating unit cell from which they are made. However, the literature on this topic is limited, primarily because of the challenge in fabricating...journal article 2015

(author)(Osteo)chondral defects (OCDs) in the ankle are currently diagnosed with modalities that are not convenient to use in long-term follow-ups. Ultrasound (US) imaging, which is a cost-effective and non-invasive alternative, has limited ability to discriminate OCDs. We aim to develop a new diagnostic technique based on US wave propagation through...journal article 2015

(author)Advanced additive manufacturing techniques such as electron beam melting (EBM), can produce highly porous structures that resemble the mechanical properties and structure of native bone. However, for orthopaedic applications, such as joint prostheses or bone substitution, the surface must also be bio-functionalized to promote bone growth. In the...journal article 2015
