The microcrystalline SiO₂ exhibits pronounced catalytic activity, significantly facilitating the conversion kinetics from Na2S2 to Na2S and enabling a shortened sodium-ion diffusion pathway.

Shortening the distance between the magnetic ions results in a 20% enhancement of the superexchange couplings, as estimated by the mean-field approximation model. To explain how plasma modifies the magnetic properties of the studied system, several attempts with heating, UV exposure, and dehydration are used to reproduce the same post-plasma magnetic phase. However, none of them are successful. Samples subjected to heat and UV show partial decomposition of the original compound, while the dehydrated material undergoes a major structural reorganization. Ultimately, the observed changes are attributed to the removal of crystallization water molecules, which apparently could only be achieved through plasma treatment.","PeriodicalId":79,"journal":{"name":"Inorganic Chemistry Frontiers","volume":"23 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2025-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144906015","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}

A Rh<small>³⁺</small> complex of a macrobicyclic sarcophagine (sar, 3,6,10,13,16,19-hexaazabicyclo[6.6.6]icosane) chelator was appended with a dibromopyridazinedione (DBPD), to produce a novel disulfide bond labelling molecule, “Rh-sar-DBPD”.

However, uncurbed dendrite growth and non-negligible water-induced side reactions could be fatal to the stability of Zn anode and commercial development of AZIBs. Herein, we construct a bifunctional zincophilic-hydrophobic interfacial layer (STA-ZnO layer) for attaining a stable Zn anode. The exposed hydrophobic alkyl chain can repel H2O to reach the Zn foil surface, efficaciously alleviating the HER and corrosion side reaction. Meanwhile, the zincophilic ZnO ensures that STA-ZnO@Zn anode accelerates Zn2+ deposition and constrains the growth of Zn dendrite. Benefitting from these advantages, symmetric cells based on STA-ZnO@Zn anode deliver long-term cycling stability over 4900 h and 4000 h at 1 mA cm−2 and 5 mA cm−2 for 1 mAh cm−2, respectively. Encouragingly, STA-ZnO@Zn anode also exhibits a high average CE of 99.81% (2000 cycles).

However, this process encounters significant technical challenges, such as extreme rarity of CTCs, interference from complex components within the blood matrix, and heterogeneous expression of surface biomarkers on CTCs. In this study, to overcome these challenges, we developed a core-shell biomimetic magnetic nano-system referred to as RPCM-pMNPs. This system consists of a polyethyleneimine (PEI) modified Fe3O4 core, which exhibits high magnetic responsiveness, and a tri-component biomimetic membrane composed of red blood cell, platelet, and cancer cell membranes. The heterogeneous membrane fusion strategy synergistically integrates the long-term circulation capabilities of erythrocytes with the immune evasion properties derived from platelets, and tumor-homing specificity (EpCAM-independent binding). This approach exhibits a high selectivity in the homologous capturing efficiency of HepG2 cells, while simultaneously effectively minimizing the non-target adsorption of RAW264.7 cells in whole blood. Additionally, the capturing efficiency and selectivity of single-layer and dual-layer cell membrane coatings were systematically investigated. Comparisons among single-, dual-, and tri-component compositions provided valuable guidance for optimal membrane selection. The proposed platform exhibits significant potential in addressing the dual challenges of biofouling and immune clearance. Moreover, its biomarker-independent capture mechanism exhibits great promise for enhancing versatility, thereby facilitating broad applicability across various cancer types characterized by heterogeneous CTC phenotypes.","PeriodicalId":79,"journal":{"name":"Inorganic Chemistry Frontiers","volume":"46 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2025-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144901285","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}
