Herein, quaternary 2D Cu–In–Zn–S NCs are fabricated using various indium precursors to expose a high proportion of (0002) crystal facets that are positively correlated with their photocatalytic activities. Theoretical calculations demonstrate that the specific adsorption of anions on the crystal facets significantly influences their anisotropic growth and, in turn, photocatalytic performance. Furthermore, 2D Cu–In–Ga–Zn–S (CIGZS) NCs are prepared by partially or completely substituting In3+ with Ga3+ cations. As the Ga3⁺ content gradually increases, the resulting photocatalytic activities follow a bell-shaped trend. The initial increase is attributed to a synergistic effect of optimized catalytic ability and a stronger electron driving force introduced by Ga3⁺ incorporation. However, excessive Ga3⁺ substitution widens the bandgap, reducing light absorption and conversion, ultimately leading to a decline in photocatalytic activities. Notably, the photocatalytic activity of Cu–Ga–Zn–S NCs with the highest hydrogen evolution rate of 1566.8 µmol g−1 h−1 under visible light surpassed those of all In-based NCs due to enhanced electron-hole separation efficiency and highly effective active sites. This study provides valuable insights into the rational design of multinary copper-based photocatalysts for solar-driven hydrogen production.","PeriodicalId":228,"journal":{"name":"Small","volume":"61 1","pages":""},"PeriodicalIF":13.3,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143713516","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}

An interweaved skeleton is established by introducing MXene nanosheets, thus improving the structure stability. Moreover, the MS composite with further reinforced structure is obtained through the synergetic enhancement of STF, which achieves high compressive strength (570 kPa) and superior impact resistance (80% impact dissipation). Meanwhile, MS composite shows reliable heat insulation and flame retardant ability, and the total heat release is as low as 4.8 kJ g−1. Furthermore, MS demonstrates an efficient shielding performance of 45.5 dB at an extremely low MXene load of 0.43 wt%. As a result, this functionally integrated composite is proving to be a competitive candidate for resistance to impact damage, thermal threats and electromagnetic interference hazards in complex environments.","PeriodicalId":228,"journal":{"name":"Small","volume":"4 1","pages":""},"PeriodicalIF":13.3,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143703447","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}

Polyethylene terephthalate (PET), widely used in packaging and textiles is one of the primary contributors to this issue. While mechanical recycling of PET results in degraded material quality, chemical recycling offers a promising alternative, enabling the transformation of PET waste into valuable monomers and precursors. In this study, postconsumer PET waste is chemically upcycled into bifunctional aromatic amine that can serve as an effective building block for polyhexahydrotriazine (PHT) aerogels. Additionally, terephthalamide moieties incorporated into the molecular design, enhance the formed network by hydrogen bonding. The resulting PHT aerogels exhibit low density, high mechanical robustness, and outstanding thermal insulation properties. More importantly, these novel PHT aerogels are designed for recyclability, enabling depolymerization under aqueous acidic conditions and efficient monomer recovery in high yield and purity. The recycled monomer can then be immediately reused to produce new aerogels with nearly identical material properties. This work highlights the potential of upcycling plastic waste into sustainable thermally superinsulating materials designed for a circular economy.","PeriodicalId":228,"journal":{"name":"Small","volume":"29 1","pages":""},"PeriodicalIF":13.3,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143703453","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, hydrogen evolution reaction (HER) and uneven Zn2+ deposition shorten lifespan, hampering commercial use. In this study, sodium dehydroacetate (SD) containing carbonyl and keto-carbonyl is introduced as multifunctional electrolyte additives, which effectively modifies the solvent shell structure, achieving a Zn2+ transference number of up to 0.72. Acting as a hydrogen bond acceptor, SD disrupts the water network structure, thereby increasing the HER overpotential by 22 mV and the corrosion potential by 9 mV. The polar functional groups in SD can reversibly capture H⁺ ions and dynamically neutralize OH⁻ ions, maintaining interfacial pH balance on the zinc anode and suppressing HER. Notably, SD not only alters the electrolyte's kinetic but also induces uniform Zn2+ deposition along the (002) plane, inhibiting dendrite growth and minimizing side reactions. This phenomenon is demonstrated in both symmetric and full-cell configurations. The Zn//Zn symmetric cell achieves an ultra-long cycling lifespan of 2800 hours at 5 mA cm⁻2, and the Zn//VO2 full battery maintains a capacity retention rate of 73.09% after 2000 cycles with a high average coulombic efficiency of 99.98%, underscoring the effectiveness of this electrolyte additive in enhancing battery performance.","PeriodicalId":228,"journal":{"name":"Small","volume":"33 1","pages":""},"PeriodicalIF":13.3,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143703576","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}

Yet one critical barrier remains: a fully transient power source with the same disappearing act. Microbial-based biobatteries have emerged as strong contenders, harnessing the power of microorganisms—found virtually everywhere—as natural biocatalysts. However, toxicity and health risks have limited these systems to single-use, often incinerable applications. Here, a transformative approach: a transient biobattery powered by commercially available probiotics that dissolves harmlessly is introduced, releasing only beneficial microbes. Fabricated on water-soluble or pH-responsive substrates, this biobattery capitalizes on a 15-strain probiotic blend to generate electricity across diverse electrode materials. By manipulating device length or encapsulating it with pH-sensitive polymers, power delivery can be fine-tuned from 4 min up to over 100 min. A single module outputs 4 µW of power, 47 µA of current, and an open-circuit voltage of 0.65 V.

Of particular interest is the activity of proteases carried by extracellular vesicle (EV) nanoparticles which are oversecreted by tumors into circulation. Current methods to analyze the activity of proteases bound to EVs require complex multi-instrument sample processing to separate EVs from plasma to quantify protease activity. This makes EV-based protease activity detection a challenge for diagnostic or point-of-care applications. Here, a method is reported that manipulates EV nanoparticles and charged molecular byproducts from protease activity using two different electrokinetic phenomena generated by a single electrode microarray within a microfluidic channel. Dielectrophoresis is first generated to recover EVs carrying active trypsin-like proteases from human plasma followed by electrophoresis for subsequent analysis of peptide cleavage products indicating protease activity. This method demonstrates signal amplification through protease catalytic activity in combination with concentrating mechanisms of dielectrophoresis and electrophoresis. Using this approach, a significant difference in protease activity is observed between patients with pancreatic cancer and benign cysts. This demonstrates dual-electrokinetic chip-based technology as a useful tool to manipulate different sized and charged analytes in a single device enabling future clinical translation of EV-based protease diagnostics.","PeriodicalId":228,"journal":{"name":"Small","volume":"170 1","pages":""},"PeriodicalIF":13.3,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143713745","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}
