Caracterización angular automatizada de sensores solares fotovoltaicos
(Instituto de Investigaciones en Energía No Convencional, 2018-12)
Este trabajo tiene como objetivo caracterizar la respuesta angular de distintosdispositivos fotovoltaicos al variar el ángulo de la radiación solar incidente. La caracterización se llevó a cabo con un nuevo equipo automatizado ...
Modeling the electrochemical response of mesoporous materials toward its application to biomolecular detection
(Wiley VCH Verlag, 2010-06)
The performance of an electrochemical sensor based on the ability of a probe to cross a mesoporous membrane partially blocked by an analyte is predicted using a numerical model. The system comprehends a membrane placed ...
Inter-comparison of environmental low-cost sensors on Arduino platform
(Institute of Environmental Sciences and Technology, 2020-12)
Low-cost sensors for relative humidity, pressure, and ambient temperature have begun to be used regularly for different applications in which the measurement or control of systems or processes is required using an affordable ...
Novel gas sensor with dual response under CO(g) exposure: Optical and electrical stimuli
(Elsevier Science, 2018-05)
In this work, a lanthanum (La) doped ceria (CeO2) film, which depicted a dual gas sensing response (electric and optical) for CO(g) detection, was obtained by the microwave-assisted hydrothermal (HAM) synthesis and deposited ...
A method for the calibration of wideband ultrasonic sensors for optoacoustics
(American Institute of Physics, 2021-06-16)
A method for calibration of ultrasonic sensors for optoacoustics that provides both frequency response and sensitivity is presented. In order to obtain the bandwidth and the frequency response of an uncalibrated sensor, a ...
Resistance and capacitance analysis of Pd-doped and undoped SnO2 thick films sensors exposed to CO atmospheres
(Elsevier, 2005-07-25)
It was found that resistance and capacitance of Pd-doped SnO2 thick films are largely modified by CO reaction with previous adsorbed oxygen at the grain surface while in undoped SnO2 thick-films adsorption and reaction ...
Wide range humidity sensors printed on biocomposite films of cellulose nanofibril and poly(ethylene glycol)
(John Wiley & Sons Inc, 2019-09)
Cellulose nanofibril (CNF) films were prepared from side streams generated by the sugarcane industry, that is, bagasse. Two fractionation processes were utilized for comparison purposes: (1) soda and (2) hot water and soda ...
Highly selective sub–10 ppm H2S gas sensors based on Ag-doped CaCu3Ti4O12 films
(Elsevier Science Sa, 2018-05)
The detection of the toxic H2S gas is of great practical, environmental and industrial interest. This work presents sensing devices fabricated with Ag-doped CaCu3Ti4O12 (CCTO) thin films using a cost effective sol-gel ...
Conduction mechanisms in epitaxial NiO/Graphene gas sensors
(Elsevier Science SA, 2020-12)
Integrated, highly sensitive and reversible sensor devices for toxic and hazardous gases in environmental pollution monitoring can be realized with graphene-based materials. Here we show that, single layer graphene grown ...
Nanostructured voltammetric sensor for ultra-trace anabolic drug determination in food safety field
(2013-11)
A sensitive electrochemical sensor for clenbuterol (CL) determination in bovine urine samples was designed. This drug was originally developed for the treatment of respiratory pathologies. However, in the livestock industry, ...
