The hydrothermal method was used to synthesize Uio66-NH2 particles and then were used with different weight ratios of 0.1, 0.2, 0.3, and 0.4. The morphology, phase analysis, functional groups evaluation, porosity, and mechanical strength of samples were determined by FESEM, XRD, FTIR, BET, and tensile tests. Moreover, pure water flux experiments and analysis of mazut/water emulsion separation were carried out using an ultrafiltration setup. The results showed that with the addition of the synthesized Uio6-NH2 to the membrane composition some of the membrane properties such as porosity, pore size, hydrophilicity, and pure water flux were enhanced. However, this ascending trend in the membrane properties was observed with an increase in the Uio66-NH2 loading up to 0.2 wt% compared to the pure membrane. These findings suggest that incorporating Uio66-NH2 into the PVC matrix improved the membrane properties and enhanced the efficiency of mazut/water emulsion separation. The PVC-MOF0.2 membrane demonstrated superior performance with high mazut rejection efficiency and shorter separation time than the pure membrane.</p></div>","PeriodicalId":600,"journal":{"name":"Iranian Journal of Science and Technology, Transactions A: Science","volume":"49 3","pages":"627 - 643"},"PeriodicalIF":1.4,"publicationDate":"2024-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143938475","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This sensor records 239 spectral bands in VNIR-SWIR regions across the 400–2500 nm range and 30-m spatial resolution and can advance remote-sensing studies for vast applications worldwide. This present research is focused on evaluating the feasibility of the L2D data sets of this satellite for mapping the alteration minerals of a porphyry copper setting, SE Iran, which is critical for exploration projects. The Daralu area is found to be associated with other porphyries such as Sarcheshmeh and Meiduk in the Urmieh-Dokhtar Magmatic Arc (UDMA) a well-known Cu-bearing region, where a wide range of world-class porphyry copper systems have been reported and studied. Based on the studies and software-based analysis of diagnostic absorption features of measured spectra, the alteration minerals mainly consist of goethite, biotite, muscovite, kaolinite, and chlorite. The Mixture Tuned Matched Filtering algorithm (MTMF) was examined for sub-pixel mapping of the desired alteration minerals. Results of this article revealed that performing this algorithm on the PRISMA dataset because of its high SNR, high spectral resolution, and high radiometric resolution was successful in sub-pixel fraction estimates of biotite, chlorite, and goethite minerals as well as SWIR spectrally similar minerals such as muscovite and kaolinite. The fraction map accuracy was verified through X-ray diffraction analysis of surficial samples. Despite the mixed-signal drawback for 30 m spatial resolution of the PRISMA and certain incompatibilities with XRD results, the output maps corresponded well with the ground criteria, so that was concluded the performance of PRISMA L2D data in mapping the alteration minerals is in line with expectations.</p></div>","PeriodicalId":600,"journal":{"name":"Iranian Journal of Science and Technology, Transactions A: Science","volume":"49 3","pages":"667 - 679"},"PeriodicalIF":1.4,"publicationDate":"2024-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143938442","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Eleven species have been reported for this genus in Iran. This genus is located in the most of the water habitats of the country and has importance in various fields such as the purification of polluted water, absorption of heavy metals, and medicinal uses. One of the important species of this genus is <i>Potamogeton nodosus</i> Poir. which shows great morphological diversity in different aquatic habitats. In this study, we first studied the quantitative and qualitative morphological characters among different populations of this species. Since the morphological marker may be affected by the environment, we also used molecular markers. For molecular study, six pairs of SRAP primers and four ISSR primers were used. The results of the combination of two markers showed the intraspecific relationships of different populations of <i>P. nodosus</i> better than each of the two markers alone. According to the results, the populations were divided into four geographical groups: north, center, southwest, and southeast. The populations of the southeast region showed more genetic differentiation than other regions. Molecular variance analysis showed intra-population variations slightly higher than inter-population variations. Regarding to relatively high genetic diversity of populations of this species, conservational strategies for aquatic ecosystems of Iran is needed.</p></div>","PeriodicalId":600,"journal":{"name":"Iranian Journal of Science and Technology, Transactions A: Science","volume":"49 2","pages":"297 - 306"},"PeriodicalIF":1.4,"publicationDate":"2024-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143583445","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
