In tissue engineering, the ultimate goal of the development of degradable porous scaffolds integrated with cells is the regeneration of new living tissue to repair biological defects. Scaffolds have certain requirements ...
The development of the present Ph.D. thesis implied the preparation of PLA and nanoclay reinforced PLA films as well as the application of different thermo-mechanical treatments. Two commercial grade PLA matrices were ...
La utilización de circona tetragonal policristalina estabilizada con 3 % mol de itria (3Y-TZP) para fabricar coronas e implantes ha sufrido una fuerte expansión recientemente debido a las buenas propiedades mecánicas, ...
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). ...
On account of environmental and safety related requirements, the majority of the most popular automotive manufacturers convey to introduce Ultra High Strength Steels (UHSS) and Press Hardened Steels (PHS) in the vehicle ...
Mullite coatings deposited by chemical vapor deposition (CVD) have been introduced and proven as excellent candidates to protect silicon carbide (SiC) from severe pitting corrosion and recession, becoming part of the new ...
Muestras de cobre electrolítico (ETP) y refinado al fuego (FRHC) previamente recocidas durante 30 minutos a una temperatura de 600 ºC, fueron sometidas a presión en canal angular de sección constante (ECAP) a temperatura ...
En el presente trabajo se analizan las estructuras celulares de espumas poliméricas inyectadas a través de los métodos de espumación física o química. Como polímero base para el estudio preliminar de moldeo por inyección ...
Esta tesis queda enmarcada en el ámbito de los biomateriales metálicos, concretamente en superficies de titanio desarrolladas para la regeneración ósea. Las aplicaciones más habituales del titanio como biomaterial son los ...
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 ...
En este trabajo se estudia la influencia de la microadición conjunta de Nb y V sobre los fenómenos de ablandamiento dinámico y estático durante y trás la deformacion en caliente. En la primera etapa del estudio se realizaron ...
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 ...
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 ...
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 ...
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 ...
The thesis at hand deals with the modification of cyclic butylene terephthalate (CBT) with the aim to improve its final properties. CBT polymerizes in an entropically-driven ring-opening polymerization into polymerized CBT ...
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 ...
In this thesis, the microstructure and mechanical properties of bulk samples manufactured with nanocrystalline iron powder are analyzed. This iron powder was obtained by a severe plastic deformation process carried in a ...
Tetragonal polycrystalline zirconia stabilized with 3 mol% of yttria (3Y-TZP) is a biocompatible ceramic showing superior mechanical properties, which are partly the consequence of phase transformation: the tetragonal ...
Up to 85% of the world population suffers from low back pain, a clinical condition often related to the intervertebral disc (IVD) degeneration (DD). Altered disc cell nutrition affects cell viability and can generate ...
