Not all reactions were effective, indicating that among the evaluated anions, CH3COO− was preferred for exchange, mainly attributed to the pre-expansion with bigger anions, facilitating the exchange with smaller anions.","PeriodicalId":17257,"journal":{"name":"Journal of the Brazilian Chemical Society","volume":"1 1","pages":""},"PeriodicalIF":1.4,"publicationDate":"2023-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68328120","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite the grave danger posed by these pollutants, there is still no adequate monitoring of their presence in the environment. The regular determination of these contaminants in the environment can play a crucial role in the protection of human health and the preservation of ecosystems. New analytical techniques allow the reproducible quantification of analytes at very low concentration levels. Molecularly imprinted polymers (MIPs), with selective recognition, have also been combined with quantum dots (QDs) and suggested as valuable materials in the construction of optical sensors. Several strategies have been proposed for the selective detection of these pollutants in recent years. Rather than employing expensive, time-consuming standard analytical methods, fluorescent quantum dots coupled with molecularly imprinted polymers can be used for developing simple, rapid and highly selective analytical methods for the detection of these pollutants. This review presents a brief discussion on the application of tailor-made polymeric materials in tandem with quantum dots for the rational construction of efficient sensors capable of determining the presence of these pollutants in aquatic environments.","PeriodicalId":17257,"journal":{"name":"Journal of the Brazilian Chemical Society","volume":"1 1","pages":""},"PeriodicalIF":1.4,"publicationDate":"2023-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68329655","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The oil extracted from baru seeds presented good thermal and oxidative stability. Moreover, the oil contains high contents of total phenolics and carotenoids. The reduction of oil-water dynamic interfacial tension was promoted by the presence of small molecules.

The role of drug analysis laboratories in EWA is very important and experts working at forensic laboratories are in the main position to detect NPS and any changes in the molecular structures. However, for this practice, it is necessary to use reliable analyses techniques for unequivocal identification. The goal of this work is to use single-crystal X-ray diffraction (XRD) to detect the presence of NPS and elucidate its molecular structure using single crystals from a seized blotter paper. XRD is also useful to prepare reference substances to produce entries to be included in Fourier transformed infrared spectroscopy (FTIR) and mass spectrometry databases, which are some of the most relevant routine techniques in forensic laboratories. This approach was used to study the NPS 25R-NBOH and 25I-NBOMe using XRD, FTIR, Raman, and nuclear magnetic resonance spectroscopies. The results showed that molecular structure methods must be used to elucidate NPS in an unambiguous manner and the potential of XRD use in the forensic area as a reference method.","PeriodicalId":17257,"journal":{"name":"Journal of the Brazilian Chemical Society","volume":"1 1","pages":""},"PeriodicalIF":1.4,"publicationDate":"2023-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68327923","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
