  • A Novel One-Step Fabricated, Droplet-Based Electrochemical Sensor for Facile Biochemical Assays
    MDPI AG, 2016
    Co-Authors: Yong Yao, Chunsun Zhang
    Abstract:

    A simple, novel concept for the one-step fabrication of a low-cost, easy-to-use droplet-based electrochemical (EC) sensor is described, in which the EC reagents are contained in a droplet and the droplet assay is operated on a simple planar surface instead of in a complicated closed channel/chamber. In combination with an elegant carbon electrode Configuration, Screen-printed on a widely available polyethylene terephthalate (PET) substrate, the developed sensor exhibits a stable solution-restriction capacity and acceptable EC response, and thus can be used directly for the detection of different analytes (including ascorbic acid (AA), copper ions (Cu2+), 2′-deoxyguanosine 5′-triphosphate (dGTP) and ferulic acid (FA)), without any pretreatment. The obtained, acceptable linear ranges/detection limits for AA, Cu2+, dGTP and FA are 0.5–10/0.415 mM, (0.0157–0.1574 and 0.1574–1.5736)/0.011 mM, 0.01–0.1/0.008 mM and 0.0257–0.515/0.024 mM, respectively. Finally, the utility of the droplet-based EC sensor was demonstrated for the determination of AA in two commercial beverages, and of Cu2+ in two water samples, with reliable recovery and good stability. The applicability of the droplet-based sensor demonstrates that the proposed EC strategy is potentially a cost-effective solution for a series of biochemical sensing applications in public health, environmental monitoring, and the developing world

  • Integración de SQL Reporting Services en aplicaciones Siemens OPCenter
    'Universitat Politecnica de Valencia', 2020
    Co-Authors: Martos García Cristian
    Abstract:

    [ES] Este TFG se ha realizado en el contexto de unas prácticas de empresa en la unidad de Automatización AC de Sothis. Su objetivo ha sido el desarrollo de una aplicación utilizando Siemens OPCenter en la que su principal funcionalidad es integrar los SSRS SQL Reporting Services en las aplicaciones de OPCenter de Siemens para múltiples clientes y apps. De esta manera, cada vez que un cliente acceda a OPCenter, se le mostrarán las características y funcionalidades de esta aplicación y se le ofrecerá este tipo de servicio orientado a mandos. Esta funcionalidad consigue incrustar en la propia solución de Siemens la visualización de los reportes, y mejorar la usabilidad al no tener que cambiar de pantalla o de aplicación. En la aplicación se puede navegar por una estructura de carpetas que organizarían distintos departamentos, que a su vez contendrían una serie de reportes personalizados. Así, sin tener que abandonar la navegación por la aplicación, los usuarios podrán visualizar sus informes, previamente creados y configurados en el Browser de SSRS. También dispone de una pantalla de configuración de servidor, en la cual se podrá crear y configurar servidores a los cuales se conectarán los diferentes usuarios para visualizar los reportes.[EN] This TFG has been developed in the scope of an internship in the AC Automation department of the Sothis company. Its goal has been the development of an application that includes some reports built with SSRS SQL Reporting Services in several Siemens OPCenter applications for multiple clients and apps. Thus, each time a client uses OPCenter, she may access this kind of managerial services. The application embeds report visualisation functionality in Siemens OPCenter and improves its usability and comfortability, since no other application will be needed in order to manage the resulting reports. To this end, a hierarchy of folders (created by different user departments) is built, and it keeps a collection of customised reports. In this way, users will have a complete application that may handle a large set of reports previously created and configured with the embedded SSRS Browser. It also has a server Configuration Screen, in which you can create and configure servers to which the different users connect to view the reports.Martos García, C. (2020).
