Cells in tissues are exposed to extracellular signals that integrate and appropriately translate into specific responses. Receptors at the cell membrane recognize a variety of soluble ligands, extracellular matrix proteins ...
Natural vesicles produced from genetically engineered cells with tailored membrane receptor composition are promising building blocks for sensing biodevices. This is particularly true for the case of G-protein coupled ...
The objective of my thesis was to develop novel techniques and methods to probe the dielectric properties of biomembranes in air and their natural environment - liquid solution. The dielectric constant ε(r) of biomembranes ...
Our bodies are complex machines whose functioning depends on multiple electrical signals controlled mainly by the nervous system. Afterwards, it is not illogical to think that one day artificial electrical impulses would ...
The main goal of this thesis is to combine electron tomography and electron energy loss spectroscopy (EELS) in the TEM, in order to obtain chemical and electronic information in 3D in the nanoscale. Tomography in the ...
En esta tesis se usa la estrategia de “Bottom-up” para la producción de materiales termoeléctricos nano-estructurados con alta eficiencia termoeléctrica. Esta técnica proporciona un amplio rango de posibilidades para ...
Carbon can be found or synthesised in different arrangements, each one with its particular properties. Curiously, the main building block of the majority of these structures (graphene) was first isolated in 2004 by A.K ...
This doctoral dissertation deals with the study of nanocrystalline tungsten oxide-based powders for gas sensing applications. Gas monitoring is receiving increasing attention due to environmental and safety reasons. Gas ...
Electronic noses (e-noses) have been utilized during the past three decades as general purpose instruments for chemical sensing. These instruments are inspired by natural olfactory systems, where fine odour discrimination ...
[spa] Esta tesis consiste en el estudio de las propiedades vibracionales de materiales de interés para la fabricación de dispositivos optoelectrónicos, operando en distintos rangos espectrales, desde ultravioleta hasta el ...
One type of photon detector is the photomultiplier tube (or PMT), most commonly used in Imaging Atmospheric Cherenkov Telescopes (IACTs). A PMT has a photoelectric cathode that absorbs light and emits an electron. A PMT ...
