(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) Over 2 million bone grafting procedures are performed each year. In the last years, synthetic calcium phosphates have drawn the attention of the researchers for their close similarity to the mineral phase of bone ...
(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 ...
(English) In this thesis, the ability to refine the grain size of a low carbon steel (deep drawing quality, DDQ) was studied by means of two different techniques of Severe Plastic Deformation (SPD). Firstly, the Repetitive ...
The world of technical textiles is present every day in more sectors. In the work presented, a new facet of textile materials has been shown, textiles as a drug excipient and functional matrix. It is known that electro-spinning ...
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) Biodegradable metals emerged as promising materials for bioresorbable devices avoiding the potential side effects of permanent implants. Among them, zinc (Zn) arose dueto its suitable degradation rate for biomedical ...
(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 ...
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) This thesis is framed in the ERC Starting Grant Project “Atmospheric Pressure plAsma meets biomaterials for bone Cancer HEaling (APACHE)”. The APACHE Project aims at evaluating plasma technology as therapy against ...
(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 ...
One of the techniques to make porous membranes from polymers is based on the stretching a polymer film containing a row-nucleated !amellar structure.This special crystalline structure may be achieved using a processing ...
(English) The restoration of the functionality of lost teeth is mainly accomplished placing dental implants. However, in the case of alveolar bone atrophies, this treatment might not be possible. Various treatments have ...
Labels misplacement in the bottles are currently causing problems in wine cellar's labelling lines. According to data provided by Codorníu and Torres cellars, 1% of the bottles present this issue. Once the wine or cava ...
(English) Oncogenic pathologies are the second leading cause of death worldwide only after cardiovascular diseases. It is estimated that, by 2030, the number of patients diagnosed with this disease will increase by nearly ...
