Lithium-sulfur batteries (LSBs) are regarded as the most promising candidate to replace Lithium-ion batteries (LIBs) in next-generation energy storage systems. Compared with LIBs, LSBs are characterized by a sixfold higher ...
The application of electron diffraction to crystallographically characterize all kinds of materials has experienced new developments that have attracted some attention in recent years. A large number of structural analyses ...
The main goal of this doctoral thesis is the development and optimization of inkjet- based technologies for hybrid electronic circuits manufacturing, as well contribute on the development of the incoming low cost electronics. ...
[spa] Actualmente el control de la concentración de etileno en las cámaras de almacenamiento de fruta proporciona información de gran interés sobre su estado. Por un lado, la fruta produce pequeñas concentraciones de etileno ...
This doctoral thesis proposes and explores a new approach to lensless microscopy, focusing on making high resolution imaging ubiquitous and low cost. A short introduction to microscopy frames the state of current techniques: ...
[eng] The aim of this thesis has been two-fold. First, to develop new processing and analysis tools and strategies for extracting information from EELS data, and second, to apply the methods to different nanoparticle systems ...
[spa] Las cubiertas del suelo son el resultado de factores naturales, socioeconómicos y de su utilización por parte de las personas en el tiempo y en el espacio. La información sobre las dinámicas del territorio es esencial ...
Point-of-Care diagnostic tests enable monitor health conditions and obtain fast results close to the patient, reducing medical costs, and allowing the control of infectious outbreaks. The interest in developing Point-of-Care ...
[eng] Additive manufacturing, also referred as 3D printing, is a layer-by-layer technique that allows producing three-dimensional objects directly from a digital model. It has enabled the fabrication of innovative products ...
In the Transmission Electron Microscope (TEM), an incident electron suffers both elastic and inelastic scattering by the solid state thin sample that is being characterised. In the event of inelastic scattering, the incident ...
The thesis reflects the research carried out on the development of truly self-powered devices. The development of devices for the scopes of Structural Health Monitoring (SHM) and Point-of-Care devices (PoC) is shown. New ...
Los sistemas de almacenamiento de energía termoquímica presentan la ventaja de usar materiales que almacenan una alta densidad energética por un tiempo ilimitado, características importantes para ser aprovechadas para ...
Recently the property of some bacteria to exchange electrons with non-soluble electron acceptors, such as minerals, has been discovered. In addition, some of these bacteria can use electrodes as the final electron acceptor. ...
[spa] Esta tesis está enfocada en la búsqueda de hitos y nuevos conceptos que permitan la mejora de un producto que actualmente está dominando el mercado en su nicho de negocio español: las tuberías de PP-RCT. La empresa ...
In some types of fire, namely, smoldering fires or involving polymers without flame, gases and volatiles appear before smoke is released. Most of the fatalities registered for fires, are caused due to the intoxication of ...
Rapid population growth is leading to many environmental problems, among which a large waste generation should be highlighted. More than 40% of these wastes correspond to organic wastes that are mainly treated by composting, ...
[eng] Additive manufacturing (AM) is a process of creating a physical object by adding material layer by layer rather than removing material through machining. It is also known as 3D printing, as it typically involves using ...
This doctoral thesis raises the idea that 3D printing can change the paradigm of radio- frequency electronics, which has been traditionally developed mainly conceiving planar topologies. A review on additive manufacturing ...
[eng] This thesis focuses on the functional design and preparation of different kind of nanocomposites and their applications in energy conversion and storage technologies, particular in OER, HER, H2O2ER and LSBs. For the ...
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 ...
