Manel del Valle Zafra, Ph.D. (1992), is a Spanish chemist, who is active in the field of analytical chemistry; he is a professor of the Autonomous University of Barcelona (AUB) and founder of the university Group of sensors and biosensors. [1]
The Autonomous University of Barcelona is a public university mostly located in Cerdanyola del Vallès, near the city of Barcelona in Catalonia, Spain.
A province in Spain is a territorial division defined as a collection of municipalities. The current provinces of Spain correspond by and large to the provinces created under the purview of the 1833 territorial re-organization of Spain, with a similar predecessor from 1822 and an earlier precedent in the 1810 Napoleonic division of Spain into 84 prefectures. There are many other groupings of municipalities that comprise the local government of Spain.
A sensor is a device that produces an output signal for the purpose of detecting a physical phenomenon.
A biosensor is an analytical device, used for the detection of a chemical substance, that combines a biological component with a physicochemical detector. The sensitive biological element, e.g. tissue, microorganisms, organelles, cell receptors, enzymes, antibodies, nucleic acids, etc., is a biologically derived material or biomimetic component that interacts with, binds with, or recognizes the analyte under study. The biologically sensitive elements can also be created by biological engineering. The transducer or the detector element, which transforms one signal into another one, works in a physicochemical way: optical, piezoelectric, electrochemical, electrochemiluminescence etc., resulting from the interaction of the analyte with the biological element, to easily measure and quantify. The biosensor reader device connects with the associated electronics or signal processors that are primarily responsible for the display of the results in a user-friendly way. This sometimes accounts for the most expensive part of the sensor device, however it is possible to generate a user friendly display that includes transducer and sensitive element. The readers are usually custom-designed and manufactured to suit the different working principles of biosensors.
Food engineering is a scientific, academic, and professional field that interprets and applies principles of engineering, science, and mathematics to food manufacturing and operations, including the processing, production, handling, storage, conservation, control, packaging and distribution of food products. Given its reliance on food science and broader engineering disciplines such as electrical, mechanical, civil, chemical, industrial and agricultural engineering, food engineering is considered a multidisciplinary and narrow field.
Dielectric spectroscopy measures the dielectric properties of a medium as a function of frequency. It is based on the interaction of an external field with the electric dipole moment of the sample, often expressed by permittivity.
An ion-sensitive field-effect transistor (ISFET) is a field-effect transistor used for measuring ion concentrations in solution; when the ion concentration (such as H+, see pH scale) changes, the current through the transistor will change accordingly. Here, the solution is used as the gate electrode. A voltage between substrate and oxide surfaces arises due to an ion sheath. It is a special type of MOSFET (metal–oxide–semiconductor field-effect transistor), and shares the same basic structure, but with the metal gate replaced by an ion-sensitive membrane, electrolyte solution and reference electrode. Invented in 1970, the ISFET was the first biosensor FET (BioFET).
Bioelectronics is a field of research in the convergence of biology and electronics.
Coprates Chasma is a huge canyon in the Coprates quadrangle of Mars, located at 13.4° south latitude and 61.4° west longitude, part of the Valles Marineris canyon system. It is 966 km (600 mi) long and was named after a classical albedo feature name. It was named from the classical Greek name for the Dez River in Persia.
Candida blankii is a species of budding yeast (Saccharomycotina) in the family Saccharomycetaceae. The yeast may be a dangerous pathogen and resistant to treatment in human hosts. Research on the fungi has therapeutic, medical and industrial implications.
TramVallès, Tramvallès or Tramvia del Vallès is a proposed tram or light rail network in the metropolitan area of Barcelona. Its name stems from the region of Vallès, which spans two counties north of the Catalan capital. The region is densely populated, includes the Autonomous University of Barcelona and current public transport services are insufficient for commuters. Following expressions of citizen support, the Generalitat de Catalunya, the governing body of Catalonia, approved the project in 2010. Tramvallès would serve the following municipalities: Montcada i Reixac, Ripollet, Cerdanyola del Vallès, Badia del Vallès, Sant Cugat del Vallès, Barberà del Vallès, Sabadell and Terrassa.
Food spoilage is the process where a food product becomes unsuitable to ingest by the consumer. The cause of such a process is due to many outside factors as a side-effect of the type of product it is, as well as how the product is packaged and stored. Due to food spoilage, one-third of the world's food produced for the consumption of humans is lost every year. Bacteria and various fungi are the cause of spoilage and can create serious consequences for the consumers, but there are preventive measures that can be taken.
Robotic sensing is a subarea of robotics science intended to provide sensing capabilities to robots. Robotic sensing provides robots with the ability to sense their environments and is typically used as feedback to enable robots to adjust their behavior based on sensed input. Robot sensing includes the ability to see, touch, hear and move and associated algorithms to process and make use of environmental feedback and sensory data. Robot sensing is important in applications such as vehicular automation, robotic prosthetics, and for industrial, medical, entertainment and educational robots.
Joan Martinez Alier is a Catalan economist, Emeritus Professor of Economics and Economic History and researcher at ICTA at the Autonomous University of Barcelona. He has made important contributions in ecological economics and political ecology, which he synthesised in his work on environmentalism of the poor.
A field-effect transistor-based biosensor, also known as a biosensor field-effect transistor, field-effect biosensor (FEB), or biosensor MOSFET, is a field-effect transistor that is gated by changes in the surface potential induced by the binding of molecules. When charged molecules, such as biomolecules, bind to the FET gate, which is usually a dielectric material, they can change the charge distribution of the underlying semiconductor material resulting in a change in conductance of the FET channel. A Bio-FET consists of two main compartments: one is the biological recognition element and the other is the field-effect transistor. The BioFET structure is largely based on the ion-sensitive field-effect transistor (ISFET), a type of metal–oxide–semiconductor field-effect transistor (MOSFET) where the metal gate is replaced by an ion-sensitive membrane, electrolyte solution, and reference electrode.
A provincial council is the administrator and governing body of a province of Spain. It is one of the entities that make up local government in Spain. The council is made up of a president, vice presidents, an executive committee and the plenary assembly of deputies.
An ayuntamiento is the body charged with the government and administration of the municipalities in Spain not bound to the regime of concejo abierto. The ayuntamiento is one of the bodies charged with Local government in Spain.
