Here, an artificial composite protective layer consisting of a Zn metal-organic framework (MOF) layer infiltrated with a hydrophobic ionic liquid 1-ethyl-3-methylimidazoline bis(trifluoromethyl sulfonyl) imide is constructed on zinc anodes. The unique porous structure of the MOF enables uniform electric field distribution, effectively inducing uniform Zn plating and stripping. Meanwhile, a small amount of hydrophobic ionic liquid can effectively isolate the direct contact between the zinc anode and the aqueous electrolyte, thereby inhibiting undesired side reactions including hydrogen evolution reaction. In addition, the cations in the ionic liquid can act as a shielding layer to suppress the tip effect. Consequently, the stability of the zinc metal anode is greatly improved. The assembled symmetric cell is able to cycle stably for over 2600 h at 0.2 mA cm-2/0.2 mAh cm-2 and over 800 h at 1 mA cm-2/1 mAh cm-2, which also exhibits lower and more stable overpotentials.","PeriodicalId":229,"journal":{"name":"Small Methods","volume":" ","pages":"e2402213"},"PeriodicalIF":10.7,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143539609","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}

Herein, perovskite films are designed by rapidly evaporating of a mixture solvent consisting of methylamine ethanol solution (MA-EtOH sol) and acetonitrile (ACN) (MA-EtOH-ACN) by dopping different amounts of formamidinium iodide (FAI) into the CH3NH2PbI3 (MAPbI3) precursor solution; as a result, the high-temperature annealing step is effectively eliminated while the perovskite solar cell efficiency remains unchanged. The in situ UV-vis absorption for monitoring the perovskite crystallization process shows that FAI retards the crystallization rate, leading to a dense and smooth film. It is also found that the synergistic effect of solvent and composition engineering reduces defect density, boosts absorption strength, and enhances film stability. Consequently, high-performance ITO/SnO2/FA0.05MA0.95PbI3/carbon device is obtained with efficiency as high as 18.74%, with an excellent short circuit current of 25.04 mA cm-2, an open circuit voltage of 1.16 V, and a fill factor of 64.53%. The carbon-based perovskite solar cells also exhibit outstanding stability. This strategy offers a reference to producing efficient and stable perovskite cells by the straightforward ink method.","PeriodicalId":229,"journal":{"name":"Small Methods","volume":" ","pages":"e2402039"},"PeriodicalIF":10.7,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143555498","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, combined investigation of PersL and ML is still in its infancy. Here, the optical property of Er3+-doped NaYF4, mainly focusing on the PersL and ML characteristic and their correlation, is studied in detail. It is shown that microscaled NaYF4:Er3+ has advantages against nanoscaled counterpart in terms of PersL and ML, consistent with the photoluminescence results. By means of pre-charging and trap-emptying cycle and thermoluminescence test, it is confirmed that the PersL and ML of NaYF4:Er3+ come from the same trapped charge carriers, and the ML belongs to the trap-controlled ML. Furthermore, the good repeatability is proven, and regulation of the PersL and ML of NaYF4:Er3+ is realized. Finally, the potential of NaYF4:Er3+ for dynamic anti-counterfeiting and dual-mode detection of X-ray radiation dose is demonstrated.","PeriodicalId":229,"journal":{"name":"Small Methods","volume":" ","pages":"e2401615"},"PeriodicalIF":10.7,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143539735","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}

This study addresses this limitation by co-doping Pb(Mg1/3Nb2/3)O3-Pb(Zr,Ti)O3 (PMN-PZT) piezoelectric single crystals with manganese (Mn) and lanthanum (La). The piezoelectric cantilevers are constructed using an optimized composition containing 1 mol.% Mn and 0.5 mol.% La, designed to operate d32-mode at a resonance frequency of 60 Hz. The piezoelectric cantilever is combined with an electromagnetic coil to complete the hybrid-MME (H-MME) generator, achieving a total root mean square power of 82.19 mW under a 5-Oe magnetic field. The H-MME generator successfully supplied the watt-level power-consuming smart farm system, which included a power management circuit, camera, microcontroller, and Bluetooth module, to transmit images to a smartphone at intervals of 1 h 30 min. These results demonstrate the potential of co-doped H-MME generators to drive watt-level IoT systems, enabling applications with high-energy demands.","PeriodicalId":229,"journal":{"name":"Small Methods","volume":" ","pages":"e2401666"},"PeriodicalIF":10.7,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143555496","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}

In this system, an aqueous graphene oxide (GO) ink interacts electrostatically with partially deacetylated chitin nanofibers (mChNF), modified with benzophenone and dispersed in 1-butanol, which serves as the external phase. Upon extrusion of the GO ink, a jammed interfacial network forms, stabilizing the printed patterns within the external suspension, which provides suitable viscoelasticity for support-free printing. This approach is further extended to inks incorporating metal-organic frameworks or cellulose nanoparticles, demonstrating the advantages of mChNF as a stabilizer. Additionally, by incorporating a conductive polymer, the inks can be tailored for programmable and conductive patterning, opening new opportunities in liquid electronics and reconfigurable systems. Finally, GO inks containing an anionic polyelectrolyte (sodium alginate) undergo osmosis-driven solidification, facilitating the demolding of high-fidelity 3D structures formed by the printed threads of struts. These structures exhibit coreshell morphologies and high mechanical strength (∼175 MPa at 4% strain).

Recently, poly(β-amino esters) (PBAEs) have emerged as promising carriers for non-viral gene delivery due to their tunable structures and high delivery efficiency. Nonetheless, the cationic nature of PBAEs raises toxicity concerns, and their lack of tissue-specific targeting capability limits their clinical application. Herein, a novel PBAE for efficient plasmid delivery is constructed, which contains disulfide bonds in the backbone and N-acetylgalactosamine (GalNAc) moieties at the terminals (GalNAc-PBAEs). To address the potential reduction in nucleic acid condensing capacity caused by end-capping PBAE with GalNAc, the commonly used end-capping amines in conventional PBAE are employed as monomers to create GalNAc-PBAEs with tertiary amine side chains. Through side-chain screening, the optimized GalNAc-PBAE exhibits enhanced transfection efficiency, surpassing that of the conventional top-performing PBAE, C28-E7, and rivaling the commercial transfection reagent Lipo2000. Importantly, the GalNAc moieties enable the plasmid-PBAE polyplex to efficiently target the liver. In a mouse model with acute liver fibrosis, the efficient delivery and expression of a representative plasmid encoding HGF significantly mitigate liver fibrosis and improve liver function, demonstrating the potential of the designed PBAE in gene therapy.","PeriodicalId":229,"journal":{"name":"Small Methods","volume":" ","pages":"e2401286"},"PeriodicalIF":10.7,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143536188","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}

Unlike traditional or biomimetic nanomedicines, synthetic biological nanomedicines are designed using gene engineering-based strategies. In this Perspective, the foundational concepts of synthetic biological nanomedicine are introduced and its relationship to, and differences from, traditional and biomimetic nanomedicine are explored. Drawing from synthetic biology, synthetic biological nanomedicine also incorporates two main approaches: top-down and bottom-up strategies.
