Hence, we proposed a TPU/PLA 3D printing film triboelectric nanogenerator (TP-TENG) to monitor basketball player posture for training effectiveness evaluation. By introducing carbon fibers, TPU/PLA/Carbon film with conductive and positive triboelectric properties was prepared. According to results, the peak power density is 58.38 mW m−2 when the load resistance of 30 MΩ is matched. Nevertheless, when TP-TENG encounters wrinkles and continues to work for a period of time, its output performance will tend to stabilize. And the open-circuit voltage (VOC), transfer charge (QSC), and short-circuit current (ISC) increase to 91 %, 92 %, and 92 %, respectively, almost the same as their original values. Furthermore, the TP-TENG sensor can recognize human posture in different basketball motion posture, including skipping, squatting, walking, running. This work can help to promote the application of 3D printing TENG in basketball sports monitoring.","PeriodicalId":9831,"journal":{"name":"ChemistryOpen","volume":"14 2","pages":""},"PeriodicalIF":2.5,"publicationDate":"2024-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/open.202400241","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142749901","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, traditional P-TENGs are constrained by the inherent strength limitations of paper. Hence, we reported a novel polyester-paper cloth-based triboelectric nanogenerator (PP-TENG) designed for mechanical energy harvesting and running motion monitoring. Compared to paper, polyester-paper cloth has higher durability and tear resistance. The PP-TENG capitalizes on the unique fluffy internal structure of polyester-paper cloth, imparting high sensitivity to pressure variations. Experimental results demonstrate that the PP-TENG achieves an open-circuit voltage (Voc) of 466.64 V, a short-circuit current (Isc) of 48.73 μA, and a transfer charge (Qsc) of 90 nC. Its maximum output power reaches 930.26 μW when connected to a 40 MΩ load. These impressive metrics underscore the potential of PP-TENG in energy harvesting applications, particularly for wearable electronic devices. The device's integration into the soles of athletic socks showcases its practical utility, providing real-time monitoring of runners' gait and step count. This integration not only enhances the functionality of sportswear but also offers valuable data for performance analysis and injury prevention, marking a significant advancement in wearable technology and intelligent textiles. This research provide a promising path for self-powered wearable sensors and flexible electronics applications.","PeriodicalId":9831,"journal":{"name":"ChemistryOpen","volume":" ","pages":"e202400373"},"PeriodicalIF":2.5,"publicationDate":"2024-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142749902","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}

Swarms of this pest have been threatening vast regions of pastures and crops in Africa, Middle East, and South Asia. The biological management of expanding swarms has become a strategy of particular interest due to environmental awareness and economic issues associated with chemical pesticides. The present review aims to explore the latest updates and information about pesticidal plants that are distributed across Africa. Searches on Web of Science, Google Scholar, PubMed, and Scopus databases from 2013–2024 revealed a total of 22 plant species probed for insecticidal activities against desert locusts. The formulation, active ingredients, and biological effects of essential oils and other extracts from these plants are presented. Despite the promising anti-insecticidal effects of the plant extracts and compounds, issues related to their solubility and instability under environmental conditions have been observed. To address such major quality defects, methods for the encapsulation of plant natural products within nanostructures are detailed. Given the presence of bioactive compounds with nucleophiles bearing functional groups, the reported plant extracts have been exploited to fabricate metal nanoparticles with inherent insecticidal activities. In this paper, a holistic overview of prepared phytochemical-coated metal nanopesticides is also presented. In summary, this study offers insights into the integration of nanoformulated natural resources as a more sustainable option to control desert locust invasions.","PeriodicalId":9831,"journal":{"name":"ChemistryOpen","volume":"14 3","pages":""},"PeriodicalIF":2.5,"publicationDate":"2024-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/open.202400271","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142726516","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among them, compound 3 h exhibited a much better inhibitory effect on HepG2 liver cancer cells compared to citral, and the IC50 value was 5.3 μM following exposure with the newly synthesized derivatives (herein named 3 h for short in this paper), which was lower than that of the cisplatin (6.5 μM). Meanwhile, the cell-cycle arrest of HepG2 cells occurred in the S phase, and the apoptosis of HepG2 cells was significantly increased with increasing drug concentration. In addition, real-time fluorescence quantification PCR and Western blotting experiments showed that the expression of apoptotic protein BAX was increased, while the expression of anti-apoptotic protein BCL2 was inhibited in a dose-dependent fashion. The results of these experiments indicated that apoptosis was promoted in HepG2 cells via apoptotic signaling pathway activated by 3 h. Furthermore, 3 h effectively decreased the phosphorylation levels of PI3 K, ATK and ERK, resulting in the inhibitions of MAPK/ERK and PI3 K/ATK signaling pathways. Briefly, 3 h has been found to show inhibitory effects on the survival of HepG2 liver cancer cells and may be used as anti-cancer drug in the future.","PeriodicalId":9831,"journal":{"name":"ChemistryOpen","volume":"14 4","pages":""},"PeriodicalIF":2.5,"publicationDate":"2024-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/open.202400112","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142726512","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
