Study on the forming limit on shear spinning process
(English) Shear spinning is an incremental sheet metal forming process where a flat metal blank or pre-form is usually converted into an axisymmetric hollow part. Several ductile metals and alloys can be shear formed either ...
3D-printed biomimetic bone
(English) Over 2 million bone grafting procedures are performed each year. In the last years, synthetic calcium phosphates have drawn the attention of the researchers for their close similarity to the mineral phase of bone ...
Multifunctional eco-friendly aerogel composites for thermal insulation and fire resistant applications
(English) Replacing petroleum-based polymers with natural alternatives requires overcoming the limitations of their thermal and mechanical properties, as well as the inherently low fire resistance of the biomass from which ...
Development of high performance cement-based composites reinforced with nonwoven fabrics from sustainable raw materials and textile wastes
(English) Currently there is a growing concern about the sustainability of the construction sector due to its great contribution to climate change. Approximately one third of carbon dioxide emissions are produced by this ...
Escenarios hacia una economía circular de los plásticos: caracterización del sector del envasado y evaluación de la idoneidad del reciclado open loop de la fracción mezclada de los residuos de envase
(English) This thesis aims to deepen in the understanding of the circular economy of plastics through a scientific and design approach. It has focused on packaging waste as it is the sector with the highest priority and ...
Afino microestructural de chapa de acero calidad DDQ mediante procesos de doblado - enderezado
(English) In this thesis, the ability to refine the grain size of a low carbon steel (deep drawing quality, DDQ) was studied by means of two different techniques of Severe Plastic Deformation (SPD). Firstly, the Repetitive ...
Cold plasma-derived oxidative stress for osteosarcoma therapy
(English) This thesis is framed in the ERC Starting Grant Project “Atmospheric Pressure plAsma meets biomaterials for bone Cancer HEaling (APACHE)”. The APACHE Project aims at evaluating plasma technology as therapy against ...
Development of an in vitro three-dimensional colorectal cancer model using cell-derived extracellular matrices
(English) Oncogenic pathologies are the second leading cause of death worldwide only after cardiovascular diseases. It is estimated that, by 2030, the number of patients diagnosed with this disease will increase by nearly ...
Modelo sistémico del proceso proyectual para una ingeniería que diseña mediante materiales avanzados
(English) The engineering design process uses a systemic model that stands out for a common pattern that has evolved from Archer (1968), through French (1985), Nigel Cross (2000) and Michael F. Ashby (2009). Although in ...
Nanotechnology-based approaches for bone tissue engineering
(English) Substantial research efforts in the field of tissue engineering have been done in the recent years to overcome the bone regeneration limitations of the human body and to treat bone-related pathologies like ...
Desarrollo de sistemas de dispersión coloidal y granulación de partículas metálicas finas
(English) One of the main goals of the powder metallurgical (PM) industry has been to develop powders that have favourable handling, geometrical and optimal metallurgical properties. Currently, there are two main methods ...
3D-printed biomimetic bone grafts: clinical validation and improvement strategies
(English) Bone defects pose a major clinical and socio-economic burden and there is a clear need for new bone grafting strategies that take into account the physical-chemical properties of the native bone, to help treat ...
Mechanical integrity of coated PcBN systems: mechanics and mechanisms involved under service-like conditions
(English) Polycrystalline cubic boron nitride (PcBN) is a composite competitive cutting tool material that excels performance when machining difficult-to-cut materials (e.g. hardened steels, superalloys, etc) due to its ...
A damage-based fatigue life prediction method for metallic alloys and composites
(English) Fatigue failures in materials have been studied for centuries, with early pioneers like August Wöhler noting that repeated loading, even below the static strength of the material, could lead to structural ...
Novel multifunctional biomimetic peptides for bone tissue engineering
(English) Mimicking bone extracellular matrix (ECM) is essential to improve cell-material interactions. In this regard, the functionalization of materials with biomolecules derived from the bone ECM is a promising approach. ...
Effects of cold atmospheric plasmas on biomaterials: hydrogels and composites with calcium phosphates
(English) This PhD thesis is framed in the European Research Council starting grant project "Atmospheric Pressure plasma meets biomaterials far bone Cancer HEaling (APACHE)". The APACHE project is focused on the design of ...
Integration of sensors on 3D-printed zirconia ceramics to be used in structural applications
(English) Zirconia-based ceramics present unique combination of mechanical, thermal and chemical properties, making them a preferred choice in automotive, aerospace, heavy machinery, defence and healthcare sectors. However, ...
Improving the performance of synthetic and biomimetic 3D-printed bone grafts
(English) Bone is the second most frequent tissue transplantation right after blood transfusion. Although it has natural self-healing abilities, bone grafts are required in critical size defects to provide mechanical ...
Promoting cardiac regeneration by biomimetic microenvironments
(English) Cardiovascular diseases are the most common cause of death in the world. The heart has a very limited regeneration capacity. Thus, following tissue damage – e.g., myocardial infarction –, heart transplantation ...
Development of a resorbable and bioactive personalized 3D-printed implant for guided bone regeneration
(English) The restoration of the functionality of lost teeth is mainly accomplished placing dental implants. However, in the case of alveolar bone atrophies, this treatment might not be possible. Various treatments have ...
