However, chromium‐based nanomaterials have been relatively overlooked in terms of their synthesis, properties, and applications. This research presents a rapid and efficient method for synthesizing chromium‐based nanoparticles (Cr NPs) with tunable fluorescence capability to detect tumor‐derived exosomes (TDEs) and implement information security at the molecular level. The synthesis process involved a straightforward procedure of mixing pre‐cooled Cr 6+ and NaBH 4 solutions for 30 min. The resultant spherical Cr NPs displayed unique fluorescence modulation (including quenching or enhancing) for various dyes and DNA with different compositions. Leveraging these fluorescence characteristics, a CD63 aptamer–Cr NPs sensing system was constructed for detecting CD63‐positive TDEs even in real samples while encoding and protecting information. In this system, fluorescence‐labeled CD63 aptamers functioned as recognition probes and information carriers, forming a stego object by adsorbing onto the Cr NPs. The specific binding of the CD63 aptamer–Cr NPs to CD63 or TDEs elicited distinct fluorescence responses, thereby enabling precise quantitative detection alongside data encryption and protection. This study provides a new extension for the preparation and application of novel metal nanomaterials, offers a new platform for the rapid detection of tumor biomarkers, and opens up a direction for the integration of sensing and information science based on molecular systems.","PeriodicalId":506315,"journal":{"name":"SusMat","volume":"6 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/pdfdirect/10.1002/sus2.70053","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147910544","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Notably, the prepared HDI‐17% exhibited remarkable mechanical properties comparable to petroleum‐based elastomers while demonstrating exceptional biodegradability. Specifically, the elastomer indicated an enzymatic degradation ratio of 82.0% within 20 days and a relative compost degradation ratio of up to 95.5% compared with lignin over 90 days. These results significantly surpass the degradation rates of other degradable PUs reported in the literature. Regarding the degradation mechanism, our findings indicated that enzymatic degradation primarily targeted the ester groups of soft segments, with the process occurring layer‐by‐layer from exterior to interior. Additionally, microphase separation significantly influenced the degradation rate. Notably, both the BPUEs and their degradation byproduct solution were found to be nonbiotoxicity, highlighting their potential for safe application within biological systems. Furthermore, the BPUEs exhibited remarkable 3D printability, allowing for the precise fabrication of complex devices.

The term regenerative refers to a process of directional differentiation without the use of external raw materials, whereby a hydrophobic plastic (PDHEA) is transformed into a hydrophilic hydrogel (PHEA) coating in response to external stimulation. Such a regenerative hydrogel coating can not only be repaired after local wear and reborn after full wear, but also be adjusted with the thickness and mechanical properties according to specific engineering requirements during differentiation. Furthermore, the regenerative hydrogel coating is applied for the surgery of artificial cartilage, with potential clinical applications such as long‐acting protection of bone tissue.","PeriodicalId":506315,"journal":{"name":"SusMat","volume":"5 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/pdfdirect/10.1002/sus2.70045","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147885129","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditional carbonate‐based electrolytes struggle to meet these demands due to their high solvation energy, elevated melting points, and poor interphase stability. In this study, we present an innovative electrolyte featuring a small‐sized aggregate solvation structure. This structure improves Li + migration kinetics and promotes inorganic‐rich interphase formation. Consequently, the graphite (Gr) anode demonstrates outstanding cycling stability, retaining 98.6% of its capacity after 1300 cycles and achieving a high‐rate performance of 254.5 mAh g −1 (over 70%) at 10 C. Moreover, this electrolyte delivers excellent rate performance for the LiNi 0.8 Co 0.1 Mn 0.1 O 2 (NCM811) cathode, achieving 118.9 mAh g −1 (65%) at 10 C. In a commercial 1 Ah Gr||NCM811 pouch cell, the electrolyte sustains more than 80% capacity at 3 C and achieves 91.5% capacity retention after 1000 cycles. Notably, even at −20°C, the cell maintains a high capacity of 0.73 Ah at 0.5 C, and at an elevated temperature of 55°C, it delivers stable cycling for over 200 cycles.

However, high‐performance inorganic perovskite solar cells (IPSCs) are generally realized by strictly controlling the environmental humidity (mostly lower than 40%) during fabrication, which is undesirable for reducing fabrication cost and promoting further industrial production. Herein, a synergistic in situ hydrolysis polymerization strategy through 3,3,3‐(trifluoropropyl)trichlorosilane (TFCS) and (3‐2‐aminoethylamino)propyltrimethoxysilane (AEMS) treatment is reported to prevent water invasion and realize efficient CsPbI 3 IPSCs in highly humid air. TFCS not only regulates the crystallization process via hydrolysis reaction, but also stabilizes the phase structure by passivating the defects and producing a hydrophobic protection layer. Additionally, TFCS facilitates in situ polymerization of upper layer AEMS, thus promoting further enhanced protection of perovskites against ambient moisture. As a result, the CsPbI 3 IPSCs fabricated at 45% humidity exhibit a dramatically improved efficiency of 20.09%, representing a record value for the inverted IPSCs fabricated in air with humidity over 40%. Moreover, the environmental humidity window for device fabrication can be broadened to 60%.

To optimize interfacial catalytic activity, structurally designing TMCs into two‐dimensional (2D) and porous structures to expose more practical surface areas and enhance electronic configurations is a common and effective strategy. Particularly, porous 2D non‐layered TMCs (2D NL‐TMCs) demonstrate richer active sites distinct from layered interfacial inertness.

Mechanistic verification reveals that leveraging transient high temperature and rapid on‐off properties of microwave effectively combines with an oxidation‐induced porosity mechanism, facilitating the evolution of porous 2D structures. These low‐dimensional nanostructures with abundant edge defect sites aid in efficient adsorption reactions of intermediate species in HER. Moreover, the successful preparation of a series of porous 2D NL‐TMCs (Mo 2 C, NbC, TaC) confirms the universality of this method, with the synthesized 2D p‐W 2 C exhibiting optimal HER performance.
