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 ...
En esta tesis doctoral se analiza la estructura y morfología inducida en láminas y placas delgadas obtenidas por distintos procesos de transformación. Éstas placas y láminas se prepararon en distintos espesores utilizando ...
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 ...
In recent years hard coatings have acquired a significant importance in the microstructural and micromechanical design of forming tools. Among the wide range of surface modification techniques, physical and chemical vapour ...
This doctoral thesis explores how ion sensors can provide spatial and temporal control of specific cellular and biomaterial activity related to bone tissue engineering applications. First it was investigated the influence ...
Con esta tesis se ha pretendido establecer las bases para la preparación y caracterización de compuestos nanoestructurados formados por laminillas de espesor nanométrico a partir de la exfoliación de un hidróxido doble ...
In the current thesis, two TWIP steels with different chemical composition were successfully subjected to Severe Plastic Deformation with Equal Channel Angular Pressing (ECAP) at warm temperature (300°C), using a die with ...
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 ...
Debido a sus excelentes propiedades mecánicas y una excelente biocompatibilidad, el uso de las cerámicas de base de circona en aplicaciones dentales y ortopédicas ha crecido rápidamente durante las últimas décadas. Sin ...
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 ...
Total hip replacement (THR) has been one of the most successful surgeries in the 21st century. Ultra-high-molecular-weight-polyethylene (UHMWPE) shows favorable mechanical and tribological properties when used as a bearing ...
El éxito clínico de los implantes dentales, fabricados en titanio comercialmente puro (Ti c.p.), está basado en la consecución de la osteointegración, es decir, la conexión directa estructural y funcional entre el hueso ...
Bone is the most transplanted tissue after blood. As pointed out by the World Health Organization, musculoskeletal diseases can potentially rise as the fourth largest cause of disability within the next years. Unfortunately, ...
Press hardening, also known as hot stamping, is a hot sheet metal forming technique which allows producing lightweight components with complex geometry and outstanding mechanical properties. For this reason, use of press ...
