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, ...
Intelligent scaffolds are designed to trigger the healing regeneration process through the controlled released or disposition of bioactive signals. The fabrication of intelligent scaffolds needs the development of novel ...
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 ...
Aquesta tesi ha consistit en el disseny, fabricació i estudi de les propietats d'aleacions Cr-Re destinades a substituir els aliatges base Pt utilitzats en els motors d'apogeu i de correcció orbital de satél.lits i ha estat ...
The field of Tissue Engineering has developed in response to the shortcomings associated to the replacement of tissues lost to disease or trauma: donor tissue rejection, chronic inflammation, and donor tissue shortages. ...
The design of smart biodegradable scaffolds plays a crucial role in the regeneration of tissues and restoration of their functionality. Advances in material science and manufacturing and in the understanding on the effects ...
The goal of this research was to determine the relations between processing, structure and properties of polycarbonate-graphene nanoplatelets (PC-GnP) foams. Using two different foaming processes (in one and two steps) ...
Titanium dental implants are a commonly used solution for the replacement of lost teeth. Even though the success rate is high, the number of infections related to the placement of the implant is still remarkable and may ...
A problem is not a problem anymore if no solution exists; therefore, in the present dissertation, a novel manufacturing technique, the In Situ Forming of a Liquid Infused Preform (ISFLIP), is proposed as a solution to some ...
El agrietamiento transversal en la superficie de los productos de colada continua es un problema que sigue provocando el rechazo de algunos de estos productos con las correspondientes pérdidas energéticas y económicas. A ...
Esta investigación pretende contribuir al conocimiento de las relaciones entre la microestructura, las propiedades y las condiciones del procesado de los materiales compuestos polipropileno-vidrio. El propósito fue el de ...
From a chemical and structural point of view, hydroxyapatite (HA) is a strong candidate in biomedical applications owing to its similarity to the inorganic components of bones and teeth. HA nanoparticles (NPs) as colloidal ...
Bone has a natural ability to regenerate. However, it cannot bridge large defects without the additional help of a supporting material. Among the different synthetic bone grafts, calcium phosphates (CaPs) are excellent ...
This PhD thesis investigated the incorporation of Polyhedral Oligomeric Silsesquioxanes (POSS) in thermoplastic base materials via melt-blending procedures. Particularly, a focus is taken on the enhancement of the thermal ...
En els darrers anys ha augmentat de manera considerable l'interès de les empreses per l'ús de materials reciclats per a la fabricació dels seus productes. Les raons principals són l'estalvi econòmic que comporta a causa ...
Vertebroplasty (VP) is a surgical procedure used to treat osteoporosis induced vertebral compresion fractures. This procedure involves the injection of bone cement into the porous vertebral body through a cannula. The ...
La peri-implantitis puede poner en riesgo la integridad funcional de un implante dental, ya que dependiendo de la severidad del daño, éste puede ocasionar la pérdida irremediable del implante. Dicho padecimiento está ...
Los materiales cerámicos son ampliamente utilizados en las restauraciones dentales como implantes y prótesis debido a sus excelentes propiedades mecánicas y estéticas y a su buena interacción con el ambiente fisiológico ...
La investigación realizada en esta tesis se ha centrado en la caracterización de la fractura de materiales compuestos por una matriz de polipropileno homopolímero isotáctico y diferentes fracciones de partículas laminares ...
