Strain-time relations of Sn-5 wt.%Zn and Sn-5 wt.%Zn-0.5 wt.%Al2O3 alloys were obtained under different constant stresses (10-25 MPa) over a temperature range from 333 K to 393 K. The results of this study shows the transient creep parameters dependence on the testing temperature and the applied stress of both compounds. This work, study the effect of adding Al2O3 nano-particles to Sn-5 wt.%Zn on the thermal, structural and tensile creep properties. The addition of Al2O3 nano-particles slightly changed the thermal properties, but improved the tensile creep resistance.","PeriodicalId":445633,"journal":{"name":"Egyptian Journal of Solids","volume":"117 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122974336","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}

The detection of fluorescence of polymer composite illustrated a fluorescence peak at 612 nm with maximum intensity at 200 ppm. The polymer composites were characterized by using DSC, TGA up to 600C, and FT-IR in the range (400-4000 cm) which did not illustrate any structure variation with the addition of Perylene dye up to 200 ppm.

The investigated system provides monitoring of ammonia concentration in water which plays a critical role for aquatic organisms due to its toxic and hazardous effects on them. Additionally, the system can sense water pH, water temperature, and ambient temperature. It is capable of periodically sensing different parameters, then sending parameters captured data to a virtual cloud called ThingSpeak that providing monitoring data remotely via internet through mobile phone or PC and analyzing them to send alert to the user when any parameter’s value is out of its safety range. The proposed system can be used in several areas interested in water quality monitoring such as monitoring and contamination detection of water bodies (lakes, rivers, ponds, etc.). Also, it provides water quality monitoring in aquaculture, and aquaponics farms that help in enhancing food productivity and food security. Furthermore, it can be used for drinking water monitoring, irrigation water monitoring, etc.","PeriodicalId":445633,"journal":{"name":"Egyptian Journal of Solids","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128892467","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}
