This study introduces a universal strategy for synthesizing high-purity lead-free perovskite precursors through a methanol monosolvent system that utilizes solubility differences. The synthesis method is scalable and universal, applicable to five lead-free perovskites such as Cs₂SnCl₆, Cs₂TeCl₆, Cs₃Sb₂Cl₉, Cs₂ZnCl₄, and Cs₂SnBr₆, all maintaining high structural and compositional integrity with purities exceeding 99.985 %. The Cs₂SnCl₆ perovskite precursors achieve a high yield of 91.7 %. The synthesized Cs₂SnCl₆ perovskite exhibits superior electron mobility and lower baseline resistance when incorporated into gas sensors, demonstrating a high response (1.98 at 20 ppm) for dimethyl carbonate (DMC) detection due to its high purity. The simplicity and effectiveness of this one-step synthesis method offer a significant advancement for the production of high-quality perovskite materials for commercial applications in sensors and optoelectronics.</div></div>","PeriodicalId":351,"journal":{"name":"Journal of Colloid and Interface Science","volume":"691 ","pages":"Article 137440"},"PeriodicalIF":9.4,"publicationDate":"2025-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143714579","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}

To stimulate the development of quasi-MOF-based materials as OER catalysts, herein a Ni-Fe quasi-MOF catalyst was prepared through the pyrolysis of MIL-101(Fe) and subsequent ion exchange with Ni²⁺.

In this study, we introduce an interfacial engineering strategy by applying a glutathione (GSH) functional layer on the surface of the Zn anode (GSH@Zn). The GSH layer not only mitigates corrosion by increasing the hydrophobicity of Zn anodes but also guides uniform Zn deposition. Moreover, the native oxides on Zn anodes are etched by glutathione, resulting in an increased electrochemical active area and reduced interfacial impedance, which improves reaction kinetics. Therefore, the GSH@Zn anode demonstrates stable, long-term plating/stripping cycling, operating dendrite-free for 4500 h at 1 mA cm⁻², significantly outperforming bare Zn anodes, which short-circuit after only 130 h.

However, to simulate biologically relevant environments, the use of aqueous buffers such as phosphate-buffered saline (PBS) would be more appropriate. In this work, we study the effect of PBS on simplified membrane models with different chain lengths and saturation states, DOPC (PC C_18:1, 1,2-dioleoyl-sn-glycero-3-phosphocholine) and DMPC (PC C_14:0, 1,2-dimyristoyl-sn-glycero-3-phosphocholine), by employing small-angle neutron scattering. We compare the structure of PC vesicles when hydrated in pure water or PBS (using heavy water), and investigate structural changes when these vesicles undergo osmotic stress exerted by different PBS concentrations and its constituent salts, with a comparison to the neutral osmolytes polyethylene glycol (PEG-400) and glucose. We furthermore explored the effects of the different constituent salts of PBS on DMPC vesicles in different thermodynamic states, at <figure><img></figure>, <figure><img></figure> and <figure><img></figure>. Our results highlight that vesicles hydrated in PBS are multilamellar whereas when hydrated in <figure><img></figure> they are unilamellar. When PBS is employed to induce osmotic shock, the formation of elongated vesicles is observed. The analysis of each salt as a constituent of PBS revealed that sodium chloride (<figure><img></figure>) is chiefly responsible for the PBS effect, probably due to its higher concentration and ionic strength. Thirdly, when osmotic stress is induced in DMPC vesicles in their gel state, a strong membrane correlation together with aggregation was induced, which was not observed when its membrane transition phase (T_m) is crossed, indicating that osmotic stress is well tolerated in fluid phase. Interestingly, the behaviour of DMPC vesicles in their fluid phase in response to osmotic stress is different from DOPC vesicles in their fluid phase, highlighting the importance of unsaturation and chain length regarding tolerance to osmotic stress. Our findings highlight the critical influence of PBS, and its method of addition, on the structure of lipid vesicles, revealing how osmotic stress shapes their morphology.
