Sensors for in vitro bone tissue engineering applications

Gustavsson, Mikael (Date of defense: 2011-07-27)

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 ...

Síntesis y caracterización de nanocompuestos de poliolefinas e hidróxidos dobles laminares

Ardanuy Raso, Mònica (Date of defense: 2007-02-09)

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 ...

Study of the microstructure and mechanical properties of TWIP steels deformed by ECAP

Wang, Lei (Date of defense: 2016-12-16)

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 ...

Study of the properties of modified cyclic butylene terephthalate and its composites

Abt, Tobias (Date of defense: 2014-07-11)

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 ...

Surface modification of zirconia-based bioceramics for orthopedic and dental applications

Flamant, Quentin (Date of defense: 2016-07-20)

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 ...

Surface stability and small-scale testing of zirconia

Camposilvan, Erik (Date of defense: 2015-07-08)

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 ...

Time dependent flow of biolubricant and suspended particles behavior within total hip replacement

Safari, Alaleh (Date of defense: 2017-03-31)

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 ...

Tratamientos de superficie sobre titanio comercialmente puro para la mejora de la osteointegración de los implantes dentales

Aparicio Bádenas, Conrado (Date of defense: 2005-04-15)

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 ...

Tuning the biological performance of calcium phosphates through microstructural and chemical modifications

Díez Escudero, Anna (Date of defense: 2017-11-13)

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, ...

Wear mechanisms in press hardening of boron steel : identification and laboratory study

Pujante Agudo, Jaume (Date of defense: 2015-12-21)

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 ...
