Wetting of real engineering surfaces occurs in many industrial applications (liquid coating, lubrication, printing, painting...). Forced and natural wetting can be beneficial in many cases, providing lubrication and therefore reducing friction and wear. However the wettability of surfaces can be strongly affected by surface roughness. This influence can be very significant for static and dynami...

Bone tissue engineering provided a promising approach for treatment of large bone defects resulting from maladies such as birth defects, trauma, or tumor resection. In vitro culture of a porous scaffold seeded with osteoprogenitor cells may enhance its bone regeneration potential. In this chapter, we describe the design of a novel perfusion bioreactor system with oscillatory flow for cultivatin...

Sintering and microstructural development in ceramics has long been studied a two-dimensional grain size-density space, with only texture (i.e. deviation of orientation from random) used to gain first insights into additional parametric spaces. Following an increased interest for boundary engineering deeper understanding dopant effects on sintering boundaries, the theory complexion transitions ...

Calcium Phosphate ceramic has been widely used in bone tissue engineering due to its excellent biocompatibility and biodegradability. However, low mechanical properties and biodegradability limit their potential applications. In this project, hydroxyapatite (HA) and calcium phosphate bioglass were used to produce porous tri-calcium phosphate (TCP) bioceramic scaffolds. It was found that porous ...

Different ceramic substances are offered in the market as bone substitute materials. These include monophasic calcium phosphate ceramics of tricalciumphosphate (TCP) or hydroxyapatite (HA), biphasic calcium phosphate ceramics and multiphasic bio-glasses synthetic calcium phosphate cements. Ceramics with appropriate three-dimensional geometry are able to bind and concentrate bone morphogenetic p...

At Fraunhofer IKTS several stationary SOFC system prototypes for biogas usage are currently under development. The prototypes are in the 2 kW range and serve as test beds for innovative, ceramic based system components for a very deep process integration of the SOFC with the biogas generation process. All system components were developed strictly following a model based design process. This con...
