Hardmetal industry is continuously seeking for high-performance products at reduced costs. In addition, it is strongly struggled by the high and volatile prices of raw materials. At this juncture, producers and end-users ...
Metastable austenitic stainless steels feature an abundance of different deformation mechanisms, which contribute to the distinguished mechanical properties of these alloys. However, these properties are known to depend ...
Los cementos de fosfato de calcio son biomateriales utilizados para la regeneración ósea. En esta tesis doctoral se estudia la influencia de la microestructura y la macroporosidad en el comportamiento biológico de un ...
Actualmente, en el área de los biomateriales destinados a la fijación y regeneración ósea, existe un interés creciente en el desarrollo de materiales que sean reabsorbibles y a su vez, capaces de estimular la regeneración ...
Un campo que despierta un interés creciente dentro del ámbito de los biomateriales para la regeneración osea es el de los cementos de fosfatos de calcio. Un cemento de fosfato de calcio consiste en una fase sólida formada ...
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 aluminio y sus aleaciones son las matrices metálicas más utilizadas para la fabricación de materiales compuestos, debido a su baja densidad, capacidad de endurecimiento por precipitación, buena resistencia a la corrosión ...
El presente trabajo de investigación se enfoca en el estudio del comportamiento a fluencia y ductilidad en caliente de los denominados aceros de construcción y su dependencia con la composición química, concretamente el ...
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 ...
