Afterward, the oxidative addition of GeCl₄ to Ge(Flu^TMS)₂ gives the digermane (Flu^TMS)₂Ge(Cl)GeCl₃, followed by a reductive elimination of GeCl₂ and the formation of the oxidation product (Flu^TMS)₂GeCl₂. A comparable behavior is observed, with the homologues ECl₄ (E = Si, Sn) stopping at different steps of the reaction. The formation of the germylgermylene (Flu^TMS)₂Ge(Cl)GeCl starting from Ge(Flu^TMS)₂ and GeCl₂·dioxane is also spectroscopically observable, followed by ligand rearrangements to the tetramer [Flu^TMSGeCl]₄. Adding a phosphine as the Lewis base has a direct influence on the stability and structure of (Flu^TMS)₂Ge(Cl)GeCl, leading to the formation of Flu^TMSGeCl·PEt₃ as a stable product. Subsequent investigations of Ge(Flu^TMS)₂ with a metastable Ge(I)Br solution show that at a ratio of 6:1 GeBr/Ge(Flu^TMS)₂ the alkyl-substituted germylene no longer acts as a redox-active agent but as a cluster building block. This link and the involvement of a germylene in insertion reactions give an indication of how the construction or expansion of Ge cluster species can operate.","PeriodicalId":40,"journal":{"name":"Inorganic Chemistry","volume":"51 1 1","pages":""},"PeriodicalIF":4.6,"publicationDate":"2024-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142809899","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, an evolved heterointerface was constructed on spherical Mn₂O₃ nanocatalysts to achieve exceptional stability while maintaining adequate activity by simply introducing La. The generation of the active Mn₃O₄–Mn₂O₃ heterointerfaces by La doping was experimentally observed, which further segregates to the surface during thermal aging and forms epitaxially grown heterostructured LaMnO₃–Mn₂O₃ with Mn atoms. The former can act as highly active sites for the deep oxidation of VOCs due to the richness in oxygen vacancies and Mn⁴⁺ ions, while the latter acts as the diffusion barrier to inhibit grain growth and produce advantageous reactive electronic structures around the interface. The La-modified Mn₂O₃ oxide reached 90% conversion in toluene oxidation at 286 °C under the high WHSV of 240,000 mL g^–1 h^–1 and slightly increased to 327 °C after thermal aging at 800 °C.

However, its luminescent intensity and thermostability still need to be further enhanced. In this work, the photoluminescence property and thermostability of CaO: Eu^2+/3+ were improved significantly by codoping a few of Cl^– ions into it. Compared with CaO: Eu^2+/3+ samples, CaO: Eu^2+/3+, Cl^– phosphors not only have tunable luminescence but also show stronger luminescence intensity and thermal stability. The emission color of phosphors can be tuned by changing the excitation wavelength; typically, strong red/blue light can be displayed under 250/362 nm excitation. More importantly, both the red and blue emissions will increase simultaneously with increasing codoped Cl^– content. When the Cl^– ion content is 0.06, the emission intensity of CaO: 0.01Eu^2+/3+, 0.06Cl^– reaches its maximum and its red and blue emission intensities increase by approximate 2.5 times and 13.2 times, respectively.

Even though there are several small molecule based Mcl-1 inhibitors reported, the delivery of Mcl-1 inhibitor at the target site is quite challenging. In this regard, we developed a series of mitochondria targeting luminescent cyclometalated iridium(III) prodrugs bearing Mcl-1 inhibitors via ester linkage due to the presence of Mcl-1 protein in the outer mitochondrial membrane. Among the synthesized prodrugs, IrThpy@L2 was found to exhibit the potent cytotoxicity (IC₅₀ = 30.93 nM) against HCT116 cell line when compared with bare Mcl-1 inhibitors (IC₅₀ &gt; 100 μM). Mechanistic studies further revealed that IrThpy@L2 quickly gets internalized inside the mitochondria of HCT116 cells and undergoes activation in the presence of overexpressed esterase which leads to the release of two cytotoxic species i.e. Mcl-1 inhibitors (I-2) and cytotoxic iridium(III) complex (IrThpy@OH). The improved cytotoxicity of IrThpy@L2 is due to the mitochondria targeting ability of iridium(III) prodrug, subsequent esterase activated release of I-2 to inhibit Mcl-1 protein and IrThpy@OH to generate reactive oxygen species (ROS). After prodrug activation, the released cytotoxic species cause mitochondrial membrane depolarization, activate a cascade of mitochondria-mediated cell death events, and arrest the cell cycle in S-phase which leads to apoptosis. The potent anticancer activity of IrThpy@L2 was further evident from the drastic morphological changes, size reduction in the solid tumor mimicking 3D multicellular tumor spheroids (MCTS) of HCT116.","PeriodicalId":40,"journal":{"name":"Inorganic Chemistry","volume":"13 1","pages":""},"PeriodicalIF":4.6,"publicationDate":"2024-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142816474","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to avoid the metastable states inherent to this method, we use the occupation matrix control (OMC) scheme, which also allows us to monitor the oxidation states of the different species. The most favorable trapping sites, oxidation states, and solubility of I, Cs, and Te are evaluated in stoichiometric UO₂. To that end, vacancy-like defects under various charge states, including uranium and oxygen vacancies, U–O divacancy and bound Schottky defects, as well as the interstitial position, are considered as potential trapping sites in UO₂. Te is found to exhibit a wide range of possible oxidation states, ranging from Te^– to Te⁴⁺, depending on the stable trapping site considered. For I and Cs, one predominant oxidation state for each fission product, namely, I^– and Cs⁺, is found. This behavior is mainly accommodated by the charge of the defects. By providing accurate trapping sites and oxidation states of volatile fission products in UO₂, this study is expected to contribute in the development of larger scale simulation methods, enabling a better prediction and mitigation of corrosion issues in nuclear fuel cladding.","PeriodicalId":40,"journal":{"name":"Inorganic Chemistry","volume":"200 1","pages":""},"PeriodicalIF":4.6,"publicationDate":"2024-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142805145","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
