Photochemiresistor Sensor Development Based on a Bismuth Vanadate Type Semiconductor for Determination of Chemical Oxygen Demand
(2020-04-22)
The present paper describes the development of a novel photochemiresistor sensor for the determination of chemical oxygen demand (COD). A chemiresistive device was produced by a thin film of the monoclinic phase of bismuth ...
Photoelectrochemical processes at interfaces of nanostructured TiO 2/carbon black composites studied by scanning photoelectrochemical microscopy
(2008)
Pulsed photoacoustic characterization of a human skin phantom with superficial anomalies has been done with a homemade sensor. The sensor was done with a PVDF film and was used in the backward detection mode. The phantoms ...
Nanomateriais semicondutores aplicados na fabricação de dispositivos eletroquímicos
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Química - PPGQCâmpus São Carlos, 2019-03-22)
This dissertation was subdivided into 3 different studies. In the first study, it was proposed the development of a photo-electrochemical system for the removal of caffeine in natural water samples. Photo-anodes made with ...
Modelagem matemática do desempenho de sensores fotoeletroquímicos, baseados no elétrodo Ti/TiO2
(Universidad Nacional de Colombia - Sede Bogotá - Facultad de Ciencias - Departamento de Farmacia, 2016-01-01)
O desempenho de sensores fotoeletroquímicos, baseados no elétrodo Ti/TiO2 (sendo um exemplo de modelagem o sensor de hidrazina), foi descrito matematicamente e o respectivo modelo foi analisado por meio de teoria de ...
Design and analysis of fiber optical distance sensor
(2005)
In recent years, fiber optics has found major applications in sensor technology. In this paper, we develop a theoretical analysis on different configurations of couples of fibers, in order to determine the optimal configuration ...
