The most commonly used of these are solar, wave, wind and flow energy. The weakest aspect of these renewable energy sources in nature is that the amount of energy produced depends on the nature conditions. The power generation capacities of these energy sources depending on the weather conditions in order to more stable them are necessary to combine. By combining more than one renewable energy source, a hybrid power generation system is created. Hybrid energy storage units are added to this hybrid power generation system to ensure persistence of energy. In this study, sea flow energy and offshore wind energy are combined and a hybrid power generation system has been created. In addition, a hybrid energy storage unit consisting of a battery and ultracapacitor has been created in order to ensure the persistence of the energy produced. All two hybrid units were simulated using MATLAB/Simulink program. By integrating these systems with each other, their dynamic behaviors were investigated under possible working conditions. The results of the simulation show that the hybrid energy storage unit supports the wind and sea flow energy.","PeriodicalId":177067,"journal":{"name":"Journal of Electronics and Sensors","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130379834","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Screening testing has been a good attempt to minimize the impact caused by high morbity and mortality rates of DENV. In this study, a simple and disposable label-free electrochemical immunosensor based on a carbon ink graphite screen-printed electrode (SPE) one-step fabricated was developed for detection of non-structural 1 protein (NS1). The SPE surface was modified by drop casting, depositing a colloidal suspension containing amine-functionalized gold nanoparticles (AuNP-NH2). AuNPs were synthetized by a photoinduced physical method, illuminating preformed gold seeds with a light-emitting diode (LED,) at blue region, by using the polyethyleneimine (NH2) as reductor and stabilizing agent. UV-VIS spectroscopy and Transmission Electron Microscopy (TEM) were used to characterize the amine AuNPs. Electrocatalytic activity of AuNPs allowed more sensitivity for a label-free detection of NS1 by square wave voltammetry (SWV), with linear response from 0.1 to 2 µg mL-1. It was found a good linearity (coefficient of correlation of 0.995 (p<0.01) and a limit of detection of 0.03 µg mL-1 NS1 for analytical responses. AuNP-NH2 synthesis provided an easy oriented immobilization of anti-NS1 antibodies by Fc portion, resulting in a simple fabrication immunosensor with relative high performance and feasibility for early diagnostic of DENV.","PeriodicalId":177067,"journal":{"name":"Journal of Electronics and Sensors","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128469953","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
