(English) Zirconia stands out among oxide ceramics for its superior mechanical properties. This approach resulted from the significant research that has been conducted since the discovery of the tbughening capabilities of ...
(English) Bone defects pose a major clinical and socio-economic burden and there is a clear need for new bone grafting strategies that take into account the physical-chemical properties of the native bone, to help treat ...
(English) Bioresorbable stents (BRS) have been envisioned as a revolution in the treatment of coronary heart disease. Ideally, stents would initially retain sufficient radial strength after implantation to prevent vessel ...
(English) Fatigue failures in materials have been studied for centuries, with early pioneers like August Wöhler noting that repeated loading, even below the static strength of the material, could lead to structural ...
The present work addresses two different applications enabled by a specific and useful property of calcium phosphate cements (CPCs): injectability. On the one hand minimally invasive procedures involving the use of CPCs ...
Foam-like aerogels based on biodegradable polymers and sodium montmorillonite (Na+-MMT) clay were prepared through an environmentally friendly freeze-drying process. Both synthesized and bio-based polymers were utilized ...
La conformabilidad de chapas metálicas suele evaluarse mediante los diagramas FLD (Forming Limit Diagrams), que informan sobre el límite de conformado de un material representado por la curva FLC (Forming Limit Curve). ...
Cemented carbides, also referred to as hardmetals, are composite materials consisting of brittle refractory carbide phase (generally WC) embedded in a metallic matrix. Such microstructure leads to an outstanding combination ...
(English) One of the most exploited tissue-engineering-based strategies nowadays is to use scaffolds that allow local stimulation of the targeted tissues, increasing therapy effectiveness while reducing toxicity. Therefore, ...
To obtain a regeneration and integration of gingival tissues onto the dental implant surface, is essential to achieve an appropriate cellular response. To promote an appropriate cellular response, materials surface has ...
Bone grafting is a common medical practice in today’s society, being bone the second most transplanted tissue worldwide after blood. Therefore, it represents a field of major interest for both, biomedical research and the ...
(English) The main objective of this work is to counteract the limitations of polylactic acid (PLA) and propose a sustainable manufacturing approach using bioblends of a rheologically modified PLA by reactive extrusion ...
The topic of this Philosophy Doctor Thesis tallies with the national project MAT2012 of the BBT group of UPC: "Pore4Bone: Biomimetic calcium phosphates: tailoring porosity from the nano- to the macroscale for osteoinduction, ...
This doctoral thesis has been carried out at the company VAC-TRON S.A., together with the Department of Materials Science and Engineering of Universitat Politècnica de Catalunya, in the Besós (EEBE) and Vilanova i la Geltrú ...
The present PhD thesis is framed within the Industrial Doctorate Plan promoted by the Generalitat de Catalunya and has been developed in cooperation between the Universitat Politècnica de Catalunya-BarcelonaTech, the Centre ...
An insufficient vascularization of the wound site is often the cause of failure in tissue regeneration. The use of cell therapy or growth factors has introduced promising results, nevertheless, they are risky, expensive ...
(English) One of the main goals of the powder metallurgical (PM) industry has been to develop powders that have favourable handling, geometrical and optimal metallurgical properties. Currently, there are two main methods ...
Titanium (Ti) has been used for decades for bone prostheses due to its mechanical performance and good biocompatibility. However, the stress shielding effect, as a result of the stiffness mismatch between titanium and the ...
Material engineering has always played a defining role in industry by improving materials and tribological properties, increasing lite time use and thus ultimately reducing material costs. Over the last two decades, ...
Most of the conventional organic-inorganic composite materials developed for bone tissue engineering do not possess intimate interactions between their constituents. As a consequence, they generally degrade in a non-homogeneous ...
