This thesis is devoted to the study of the optical and vibrational properties of indium nitride (InN) and indium gallium nitride (InGaN) at room and high-pressure conditions. For this purpose, we have employed spectroscopic ...
Gas sensors can be found in many activities ranging from environment protection, risk prevention, agriculture and even in food, chemical, and petrochemical industries. There exist different technologies for gas sensors ...
Printed electronics (PE) is a set of printing methods used to create electrical devices on various substrates. Printing typically uses common printing equipment suitable for defining patterns on material, such as screen ...
La caracterización eléctrica local a escala nanométrica cobra un rol esencial en diversos campos de la biología. La caracterización eléctrica de muestras biológicas proporciona una visión sobre diferentes aspectos de ...
El progreso en el área de la microfluídica y en las metodologías de cultivo celular in vitro está posibilitando el desarrollo de sofisticados dispositivos que tienen como finalidad tratar de imitar algunas de las funciones ...
The air and environment quality is, nowadays, one of the main political concerns of the governmental institutions. Suitable gas detection is nowadays an important requirement, which is provided by gas sensors. Metal oxide ...
The large abundance of bacterial growth niches provide a rich diversity of bacterial traits. These are usually characterized using traditional microbiology research tools, and newer characterization techniques (which focus ...
Transferring nanotechnology into marketable products and services is still considered a major challenge. In Europe, this issue has been identified as a weakness, not only for nanotechnology, but also for the other five Key ...
Growing global emission of carbon dioxide gas (CO2) reflects the world’s energy dependence on fossil fuels. The conversion of CO2 emission into value-added products, like fuels completes a circular CO2 economy which ...
En el momento de la realización de esta tesis doctoral, sobre el año 2004, la tecnología RFID empezaba a crecer, básicamente, gracias a la mejora en el control de stocks de los almacenes que implicaba posibilidad de ...
The soaring global demand for flexible, wearable and transparent devices has been driven by the advent of the Internet-of-Things (IoT), where smart electronic objects are expected to be, at anytime and everywhere, aware ...
Most of the current in vitro cell culture models do not reproduce the anatomy of tissues and physiological behavior of cells in vivo and provide misleading results when compared to the real tissue. Microfabrication ...
The aim of this work is the development of a modelling methodology for the fast analysis of non-radiative multilayer RF passive components without compromising solution accuracy. Instead of following a compact model approach, ...
In the world around us, it is easy to think in different situations in which there are temperature gradients available. These could be converted into a great source of energy if using the proper technology. Thermoelectric ...
El objetivo general de esta tesis doctoral fue el desarrollo de biosensores basados en aptámeros para la detección de bacterias enteropatógenas. Para ello se estudiaron diferentes estrategias de detección gracias a las ...
Although an extensive number of investigators, during the arise of this printed materials technology, were devoted to make very interesting discoveries concerning the most used sol-gel precursor to thermally produce ZnO, ...
Recent progress in analytical chemistry instrumentation has increased the amount of data available for analysis. This progress has been encompassed by computational improvements, that have enabled new possibilities to ...
The use of radiofrequency in biomedical devices is taking on increasing significance due to its contributions to the prevention, diagnosis and treatment of diseases, either for minimally invasive remote monitoring of ...
Positron emission tomography (PET) is a molecular imaging technique used for several decades in nuclear medicine that provides precise physiological information of the human body, what is crucial in oncology, cardiology, ...
This Thesis has been focused on the fabrication and characterization of different CMOS- compatible materials in order to determine both their electro-optical and resistive switching properties. Basically, two materials ...
