From Ca3Be(SeO3)4 to SrBe(SeO3)2, the birefringence range from 0.005@546 nm to 0.058@546 nm. Theoretical calculations confirmed the dominant role of [SeO3]2- in the optical anisotropy of these two crystals.

In this study, phosphating and vacancies engineering through Ar plasma-assisted is achieved via a single-step process. Taking CoFePv with phosphorus vacancies (Pv) as bifunctional electrocatalysts, it effectively promotes both the oxygen evolution reaction (OER) and hydrogen evolution reaction (HER), thereby significantly facilitating overall water splitting (OWS) in alkaline media. In OER and HER processes, the driving potentials needed to attain current density of 1 A cm-2 are only 382 and 367 mV, respectively. Furthermore, the CoFePv (+, −) OWS electrolyzer is capable of maintaining a current density of 2 A cm⁻² at 1.98 V under simulated industrial settings (6 M KOH, 80°C). It also demonstrates stable performance at a current density of 0.5 A cm⁻² for a duration of 100 hours. In-situ Raman spectroscopy observations show that Pv induce rapid catalyst phase reconstruction, thereby significantly enhancing the OER performance of CoFePv. Density functional theory (DFT) calculations demonstrate that phosphorus vacancies can modulate the electronic properties of Co-Fe-P, facilitate electron transfer, as well as optimize the adsorption and desorption of reaction intermediates.","PeriodicalId":79,"journal":{"name":"Inorganic Chemistry Frontiers","volume":"1 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2025-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143451956","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This bond length remains nearly unchanged compared to previously reported UN@C82 isomers, suggesttng that the intrinsic nature of the encapsulated U≡N triple bond was not affected by cage size. Furthermore, combined with the previous studies about the metal position and the symmetry plane of the carbon cage, we discover that in monometallic endohedral metallofullerenes, the encapsulated metal atom preferentially aligns not only with the symmetry plane but also with the symmetry axis of the fullerene cage, namely the symmetry elements of the carbon cage, thereby preserving the overall molecular symmetry.

Recently, sonodynamic therapy (SDT) is at the forefront of the research on biomedicine, yet, the employment of sonosensitizers and SDT on antifungal infections is still on its early stages. Herein, we designed and synthesized a series of Ru(II) complex-based sonosensitizers (RuH-RuBr) with enhancing ultrasound-triggered ROS generation for antifungal applications. The heavy atom (etc. Br) engineering strategy has been well employed to narrow the HOMO-LUMO energy gap of Ru(II) sonosensitizers, particularly in RuBr, which resulted in a significant boost in ROS generation (11.8 fold). In vitro results indicated that RuBr demonstrated both good anti-Candida albicans activity (MIC = 5 μM) and low mammalian cells toxicity (survivial rate > 80%) under US irradiation. Further mechanism investigation suggested RuBr initially aggregated on the fungal cell membrane and subsequently ultrasound-activated ROS accumulation, leading to mitochondrial damage and triggering changes of mitochondrial membrane potential. In vivo studies also revealed that RuBr exhibited similar antifungal performance but lower systemic toxicity when compared to the conventional clinical antifungal amphotericin B (AmB). This research offered significant insights into the design of high-performance sonosensitisers and lay the foundation for innovative antifungal therapeutic strategies.","PeriodicalId":79,"journal":{"name":"Inorganic Chemistry Frontiers","volume":"1 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2025-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143426994","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
