Results: Three types of sponges, each Clathria reinwardri (CR) lived on medium coral reef cover, live coral and partly on the abiotic component. Hyrtios erectus (HE) and Callyspongia aeresuza (CA) were obtained from damaged coral cover, some sandy live coral and abiotic components.Inhibition of CR > CA > HE sponge methanol extract against the growth of fungi and bacteria. The inhibition of sponge methanol extract against the growth of Escherichia coli (EC) and Staphylococcus aureus (SA) and Malassezia furfur (MF) fungi was the largest by CR sponge methanol extract, but did not have inhibitory activity against Candida albicans (CA). The growth and characterization of the metabolites produced by sponges are influenced by the environmental conditions of coral reef growth and cover.","PeriodicalId":13712,"journal":{"name":"INTERNATIONAL CONFERENCE ON ENERGY AND ENVIRONMENT (ICEE 2021)","volume":"42 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84859876","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 compounds were initially prepared using the hydrothermal method at 180°C, and part of the active materials were reheated at 500°C in the air to improve the crystallinity and reduce the impurities. The materials were characterized by X-ray diffraction, scanning electron microscopy (SEM), Raman spectroscopy, and BET surface area. Anodic electrochemical behavior was examined by cyclic voltammetry (CV), galvanostatic cycling, and electrochemical impedance spectroscopy (EIS). Results show that (Fe1/2Sb1/2Sn)O4 reheated at 500°C delivers a better capacity of ∼400 mAh/g at 0.005-1.0 V voltage range up to 60th cycle. When we cycled a higher cut-off voltage of 0.005-3.0V, higher reversible capacity and higher capacity fading were noted due to alloying and conversion reaction of these mixed oxides.

In this study, a digester reactor will be developed to produce biogas and benefit from the fertilizer produced from the reactor using animal waste. Animal dung is a valuable source of nutrients and renewable energy. However, it is left to decompose in the open without benefiting from it, causing serious environmental problems, but its use as a raw material in the production of biogas will return to the community of many benefits and eliminate environmental problems. Furthermore, most of the energy needs in Oman is met from the fossil fuels and LPG which are non-renewable energy types of sources which may end one day, biogas which is a renewable energy to some extent can replace LPG. Biogas is a colourless, light gas (half the air density) that ignites in the air as a very high-temperature, blue flame that does not pollute the environment. Its thermal capacity is 5513 kcal/m3. Biogas can widely use in different walks of life such as cooking, electricity generation, produce heat, and some agriculture uses. Experiment was conducted in a laboratory scale 6 L bioreactor, to test the effectiveness of horse dung in biogas production. Experiment was done to test a horse dung slurry as an inoculum for the bioreactor with ethanol. The results obtained show that the gas production has increased with respect to the number of days with the highest production of biogas was obtained after the addition of ethanol as a catalyst for decomposition, which amounted to 2095 ml during the last five days.","PeriodicalId":13712,"journal":{"name":"INTERNATIONAL CONFERENCE ON ENERGY AND ENVIRONMENT (ICEE 2021)","volume":"104 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79225966","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}
