Herein, we report a high specific surface area carbon cloth (CC@ZnO) with uniform dispersion of nano zinc oxide as a collector for lithium metal battery (LMB). The uniformly dispersed zinc oxide in the CC@ZnO helps to achieve consistent lithium nucleation and growth with its lithophility. The high specific surface area of the CC@ZnO can promote the nucleation and growth of metallic lithium inside the current collector, greatly alleviating the adverse effects of the hostless nature of the metallic lithium anode. By utilizing this three-dimensional composite carbon cloth as a collector in lithium metal batteries, the Coulombic efficiency of lithium deposition and stripping is improved. The Li–Cu asymmetrical battery achieved a Coulombic efficiency of 97.6% after 120 cycles at 3 mA cm^–2, with a deposition capacity of 3 mAh cm^–2 in an ether electrolyte without the addition of lithium nitrate.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"16 8 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144211673","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, current technologies predominantly focus on in vitro nanodrug transport, lacking an integrated strategy for the efficient capture and directional transport of large microscale cargo, particularly for biological targets. Here, we propose a dual-stage propulsion strategy for biohybrid microrobots, enabling the coupled capture and directional transport of large targets. Inspired by the multistage propulsion of rockets, the microrobots first utilize the autonomous motility of microalgae to establish a self-propulsion-driven primary phase. Surface functionalization creates a dynamic 3D biomimetic capture interface, enhancing the target capture efficiency. Subsequently, an external magnetic field activates a secondary propulsion mechanism, enabling precise directional transport. As a proof of concept, <i>Chlamydomonas reinhardtii</i> was employed as the biological carrier and noninvasively integrated with 2 μm magnetic beads to construct dual-actuated biohybrid microrobots. This design preserved the natural motility of the microalgae while providing abundant aptamers and strong magnetic actuation. Using 20 μm polystyrene microspheres and circulating tumor cells as model targets, we successfully demonstrated high-efficiency capture (up to 93%) and directional transport (14 μm/s) of large microscale targets, highlighting the potential of this strategy for biomedical, environmental, and analytical applications.</p>","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":" ","pages":""},"PeriodicalIF":8.3,"publicationDate":"2025-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144214314","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}

Printing as an alternative fabrication method to conventional TFT manufacturing methods can deliver some benefits, such as simultaneous film deposition and patterning, good scalability, low cost, and material-saving features. However, the high annealing temperature needed for ink-to-metal oxide conversion and film densification, compounded by the poor patterning resolution of conventional printing methods, still limits the use of printing in the fabrication of flexible metal oxide TFTs. Atomic layer deposition (ALD) has recently emerged as a promising fabrication method for high-performance metal oxide TFTs that can offer more conformal film growth, precise film thickness, and higher film quality at low temperatures compared to sputtering, spin coating, or printing. Although ALD-based ZnO TFTs patterned with photolithography exhibit good electrical properties, they cannot be readily scaled to a high-throughput fabrication. Very little attention has been paid so far to the combination of low-temperature ALD growth with printing to obtain more scalable manufacturing of high-performance thin-film electronics. To overcome this challenge, we propose high-resolution reverse-offset printing (ROP) of a simple polymer resist to pattern an ALD-grown ZnO film at few μm resolution to fabricate TFTs. In this work, we report high-performance ZnO TFTs that are ALD-grown at a low temperature of 150 °C and ROP-patterned with promising stability and uniformity, a high field-effect mobility (μ_FE) of ∼16.6 cm² (Vs)⁻¹, an almost zero turn-on voltage (<i>V</i>_on) of ∼−0.49 V, a high current on–off ratio (<i>I</i>_on/<i>I</i>_off) of &gt;10⁸, a low operation voltage (<i>V</i>_op) of ≤5 V, and a negligible hysteresis (<i>V</i>_hyst) of ∼0.13 V.

This account comprehensively summarizes the recent advancements and challenges associated with ionic diodes. It begins with an overview of various ionic diode designs, categorized into rigid and flexible types, to give a clearer understanding of this evolving field. The rigid ionic diodes manifest a notably high rectification ratio of 1600, exhibiting an exceptional rectification performance, while their flexible counterparts achieve a ratio of approximately 200, realizing a trade-off between flexibility and electronic performance. Typically, gel ionic diodes, which exemplify a promising blend of bionics and flexible electronics, are highlighted.

However, simultaneously achieving transparency, high sensitivity, and robust mechanical performance remains a major challenge. In this study, we present a transparent and stretchable flexible composite sensor fabricated by combining poly(vinyl chloride) (PVC) with dibutyl adipate (DBA) and incorporating a low concentration (0.1 wt %) of LM as the conductive phase. The sensor exhibits a transparency of 50.12%, resulting from the optical clarity of the PVC/DBA matrix, the nanoscale dispersion of LM droplets, and the formation of Ga³⁺ ions upon partial surface oxidation, which collectively reduce light scattering and absorption. PVC also acts as a stabilizing matrix, forming a protective interface around LM droplets to enhance dispersion and interfacial stability. The resulting composite sensor demonstrates excellent stretchability (530%), high sensitivity (gauge factor = 4.27), and reliable performance in humid and saline environments.

In this study, we report the use of difluoromethylornithine (DFMO), aPD-L1, and Indocyanine Green (ICG) in combination with target TAMs for their repolarization. DFMO repolarizes TAMs by inhibiting the expression of aconitate decarboxylase 1 (ACOD1), while aPD-L1 blocks the PD-1/PD-L1 immune checkpoint on TAMs, achieving efficient phenotypic switching and enhancing the phagocytic activity against glioblastoma (GBM). When combined with the photothermal agent ICG, the photothermal effect induces immunogenic tumor cell death and further strengthens the repolarization of TAMs. This increases the conversion efficiency of TAMs, reverses immune suppression at the tumor site, and transforms the anti-inflammatory “cold” tumor into a pro-inflammatory “hot” tumor. This approach showed better therapeutic effects in an orthotopic glioma model in mice, with the repolarization of our combined treatment DFMO + N-aP@ICG (nanovesicles containing aPD-L1 and ICG), increasing by 179% compared to other combined treatments for glioma.
