Presently, the “perovskitizer” moieties in the perovskite cage are confined exclusively to small-size cations (such as Cs+ and CH3NH3+), while high-quality crystals of 2D OIHPs containing larger cation (e.g., guanidinium, G+) cation as perovskitizer remain quite scarce for detecting X-ray application. Here, we have successfully fabricated nanoGray-responsive self-driven X-ray detector using single crystals of a polar 2D hybrid perovskite, IA2GPb2I7 (where IA is isoamylammoni-um), of which G cations are confined inside the perovskite cages. The dynamic freedom of IA+ and G+ organic cations' molecular movements sup-plies the impetus for the crea-tion of electrical polarization. Upon X-ray radiation, a bulk photovoltaic voltage of 0.74 V is generated due to the spon-taneous electric polarization, which affords the source for self-driven detection. The grown high-quality inch-size crystals show high resistivity (1.82 × 1010 Ω cm) and huge carrier migration lifetime product (μτ = 2.7×10-3 cm-2 V-1). As expected, X-ray detector fabricated on high-quality crystal enables dramatic X-ray detection performances un-der 0 V, boasting an excellent sensitivity of 115.43 μC Gyair−1 cm−2 and an impressively low detection limit of 9.6 nGyair s−1. The detection limit is superior to many known perovskite X-ray detectors. The investiga-tion focuses on the rational design and engineering of new hybrid perovskites to-ward high-demanded self-powered X-ray detector.","PeriodicalId":86,"journal":{"name":"Materials Chemistry Frontiers","volume":null,"pages":null},"PeriodicalIF":7.0,"publicationDate":"2024-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142249121","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The antimicrobial efficacy of endodontic irrigants in clinical use is contingent upon their concentration; however, elevated concentrations engender significant risk to tissue integrity. Consequently, we advocate for an innovative and benign sonodynamic antimicrobial approach. This method employs the sonosensitizer DPA-SCP, which, under the influence of low-frequency ultrasonic waves, catalyzes the generation of copious reactive oxygen species (ROS). Empirical evaluations indicate that DPA-SCP demonstrates a robust antibacterial capacity towards E. faecalis suspensions and biofilms established on the internal surfaces of root canals. Moreover, its bactericidal impact is comparable to the use of 5.25% sodium hypochlorite. Moreover, DPA-SCP demonstrates markedly reduced cytotoxicity towards fibroblasts relative to conventional endodontic irrigants, and the thermal elevation induced by ultrasonic application remains within non-detrimental limits. This sonodynamic disinfection paradigm presents a valuable and prospective clinical application in endodontic sanitation.","PeriodicalId":86,"journal":{"name":"Materials Chemistry Frontiers","volume":null,"pages":null},"PeriodicalIF":7.0,"publicationDate":"2024-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142249124","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, conventional DSSCs require high-temperature processing for working and counter electrodes (WEs and CEs, respectively), limiting their diverse applications. Low temperature processing for highly catalytic CEs, particularly using poly(3,4-ethylenedioxythiophene) (PEDOT) as a conducting and catalytic replacement for platinum, shows potential for increased efficiency under various light conditions. Despite the high catalytic activity of PEDOT, its limited solubility and processing technologies (e.g., electrochemical deposition and spin-coating) have necessitated the interest in composites of PEDOT either with poly(styrene sulfonate), metal compounds, or in combination with carbon materials, aiming to overcome these limitations. With the combined properties of high conductivity, catalytic activity, porosity, and low temperature processability, these CEs based on PEDOT have higher scientific and industrial prospects. Moreover, the highly transparent PEDOT-based CEs can also be used for bifacial application in DSSCs. To continuously draw interest to further research on these materials, this review provided an overview of PEDOT-based CEs for rigid, flexible, and indoor applications of DSSCs. Additionally, we discuss the changes in electronic, chemical, and stability properties associated with the formation of each type of composite material. The challenges and prospects of PEDOT-based materials are further highlighted, which pave the way for performance improvements in the future, as well as identifying other potential applications in the semiconductor industry.","PeriodicalId":86,"journal":{"name":"Materials Chemistry Frontiers","volume":null,"pages":null},"PeriodicalIF":6.0,"publicationDate":"2024-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142202604","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nonetheless, MnO is commonly perceived to exhibit insufficient electrochemical activity and is deemed unsuitable for Zn2+ storage. Herein, MnO-embedded PDA-derived carbon (MnO/C-PDA) is utilized as the cathode material for ZIBs, and its electrochemical behavior in ZnSO4 electrolytes with varying MnSO4 concentrations is investigated. The results indicate that the incorporation of manganese salt electrolyte notably enhances electrode capacity, though excessively high concentrations of manganese salt diminish electrode activity. In the electrolyte containing 0.2 M MnSO4, MnO-C/PDA exhibits a capacity of 295.4 mA h g−1 at 0.1 A g−1, with negligible capacity degradation even after 100 cycles. Ex situ characterization reveals that during the charging process, MnO transformed into amorphous MnOx, accompanied by the deposition of manganese salts forming MnOx, while the discharge process involved the co-insertion of Zn2+ and H+. This work is anticipated to enhance comprehension regarding the charge and discharge mechanisms of MnO, thus aiding in the development of manganese oxide cathodes tailored for ZIBs.","PeriodicalId":86,"journal":{"name":"Materials Chemistry Frontiers","volume":null,"pages":null},"PeriodicalIF":7.0,"publicationDate":"2024-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142202610","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the easily recombination of electrons and holes weakened the electrical stimulation effect. Herein, a core-shell Bi2S3@PPy nanorod was prepared via in-situ hydrothermal polymerization of conductive polypyrrole (PPy) on Bi2S3, and then blended into poly-L-lactic acid powder to fabricate nerve conduit by laser additive manufacturing. Under the rotating magnetic field, the conductive Bi2S3@PPy in the conduit could cut the magnetic inductance line to generate induced electromotive force, which could drive the electron and hole of Bi2S3 moved to the opposite direction and thereby achieving their efficient separation. Results indicated that the enhanced electron-hole separation boosted the generation of photocurrent, with an output current of 7.5 μA, significantly higher than the photocurrent under light irradiation (5.0 μA) and the induced current under magnetic field (2.5 μA). The immunofluorescent staining demonstrated that the enhanced photocurrent could up-regulate the expression of neuronal marker Nestin and GFAP. Moreover, the Ca2+ intracellular influx was improved, which manifested that the differentiation of BMSCs into neurons was provoked. Overall, this work might provide a potential wireless electrical stimulation strategy for accelerating nerve repair.","PeriodicalId":86,"journal":{"name":"Materials Chemistry Frontiers","volume":null,"pages":null},"PeriodicalIF":7.0,"publicationDate":"2024-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142202606","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
