Nanowire ordered Arrays for electrochemical sensing of H2O2

2016

In this work, we present the performance of nanostructured array of Cu for electrochemical sensors of hydrogen peroxide. Nanostructured sensors are obtained by template synthesis in commercial polycarbonate membranes. Arrays of Cu nanowires were fabricated through a displacement deposition reaction that permits to obtain nanostructures directly and without the use of an external power supply. To test the performance of nanostructured sensors, electrochemical experiments were carried out in an aqueous solution with different amounts of hydrogen peroxide. In order to obtain sensors with stable performance, we found that it is essential to increase wettability of the nanostructures through add…

Latest Developments and Results of Radiation Tolerance CMOS Sensors with Small Collection Electrodes

2020

The development of radiation hard Depleted Monolithic Active Pixel Sensors (DMAPS) targets the replacement of hybrid pixel detectors to meet radiation hardness requirements of at least 1.5e16 1 MeV neq/cm2 for the HL-LHC and beyond. DMAPS were designed and tested in the TJ180 nm TowerJazz CMOS imaging technology with small electrodes pixel designs. This technology reduces costs and provides granularity of 36.4x36.4 um2 with low power operation (1 uW/pixel), low noise of ENC < 20 e-, a small collection electrode (3 um) and fast signal response within 25 ns bunch crossing. This contribution will present the latest developments after the MALTA and Mini-MALTA sensors. It will illustrate the imp…

Ghost stochastic resonance in FitzHugh–Nagumo circuit

2014

International audience; The response of a neural circuit submitted to a bi-chromatic stimulus and corrupted by noise is investigated. In the presence of noise, when the spike firing of the circuit is analysed, a frequency not present at the circuit input appears. For a given range of noise intensities, it is shown that this ghost frequency is almost exclusively present in the interspike interval distribution. This phenomenon is for the first time shown experimentally in a FitzHugh-Nagumo circuit.

The state of research on software engineering competencies: A systematic mapping study

2022

Considering the critical role of software in modern societies, we face an urgent need to educate more competent software professionals. Software engineering competencies (SEC) are considered the backbone of successfully developing software products. Consequently, SEC has become a hotspot for software engineering research and practice. Although scientific literature on SEC is not lacking, to our knowledge, a comprehensive overview of the current state of SEC research is missing. To that end, we conducted an extensive and systematic review of the SEC literature. We provide an overview of the current state of research on SEC, with a particular focus on common SEC research areas. In addition to…

This paper discusses the process of transformation of the (coal) mining heritage from the 1990s up to the present day. It draws attention to the development of new trends related to the conservation and documentation of that heritage. In the last decades, numerous open air museums, tradition parks, monument trails have been created, which, through various forms of activities, encourage people to take interest in the history and traditions associated with mining. Today, the mining heritage has a significant potential, especially in terms of popular forms of tourism (industrial, urban, thematic). Due to institutional and financial support, also on the part of local environments, and a well-de…

Programación de microrrobots por bloques

2016

Material docente perteneciente a los cursos y talleres de difusión llevados a cabo en la ETSE-UV dentro de los programas del Servei d'Informació i Dinamització (SeDi) de la Universitat de València (Aprén Emprén, Ciència ARA, Talleres de Secundaria, Conèixer y NauJove). En los entornos tecnológicos educativos, se viene adoptando la práctica del uso de robots como incentivo a la programación y diseño de sistemas/automatismos. Debido al atractivo que éstos suscitan en los estudiantes, se genera un clima propicio para el aprendizaje. La programación y el montaje de robots no sólo tienen su aplicación en sí mismos, sino que permiten dar una idea global del funcionamiento de sistemas que se desar…

Academic achievement and self-concept of deaf and hard-of-hearing and hearing students transitioning from the first to second cycle of primary school…

2018

ABSTRACTThis study was done to examine the transition of deaf and hard-of-hearing (DHH) and hearing students from the first cycle (Grade 4) to the second cycle (Grade 5) of primary education in Ethiopia. Academic achievement and self-concept were measured longitudinally with 103 DHH and hearing students. Participants were selected from three different settings (special schools, special classes and regular schools). Self-Description Questionnaire I (Marsh, H. W. 1990. Self-Description Questionnaire – I (SDQ I). Manual. MacArthur, NSW, Australia: University of Western Sydney) was used to measure the children’s self-concept. The results showed a decrease in the academic achievement and academi…

O2-Loading Treatment of Ge-Doped Silica Fibers: A Radiation Hardening Process

2016

International audience; The effects of a high-pressure O2-loading treatment on the radiation response of Ge-doped optical fibers (OFs) were investigated. We found that the incorporation of high concentration of interstitial molecular oxygen remarkably enhances the resistance to ionizing radiation of Ge-doped OFs in the UV-Visible domain and, at the same time, improves the transmission of UV light in the unirradiated OF sample. By comparison with previously reported results, the O2-loading treatment turned out to increase the radiation resistance of Ge-doped OFs more efficiently than F or Ce codoping. The understanding of such amelioration relies in basic radiation-induced mechanisms that we…
