Current solar-coupled metal-air systems rely on UV or visible light harvesting and suffer from inferior charge separation ability and limited solar utilization. Additionally, sunlight action behavior/mechanism in some useful scenarios (seawater electrolytes, low-temperature) is underexplored. Herein, through gradient homojunction design via donor-acceptor (D-A) engineering, it exploits a novel full-spectrum-responsive polymer homojunction photoelectrode (PGH) for sunlight-coupled seawater-electrolyte-based Zn/Na-air batteries (Zn-SWAB/Na-SWAB) with boosted sunlight utilization and energy efficiency at lower temperatures. By stacking three pre-designed analogous [A<sub>1</sub>-D<sub>1</sub>]<sub>m</sub>-[A<sub>1</sub>-D<sub>2</sub>]<sub>n</sub> copolymers with gradient energy-levels and rich heterocycles, PGH integrates separate metal-free active sites for oxygen reduction/evolution reaction (ORR/OER), efficient photothermal effect with full-spectrum-absorption, and superior photoelectric effect with high charge-separation efficiency. Thus, PGH under simulated-sunlight produces remarkably-enhanced photocurrent up to 3.2 and 21.4 times during ORR/OER in near-neutral electrolytes. This endows sunlight-coupled PGH-enabled Zn-SWAB and Na-SWAB with low voltage gaps of 0.08/0.25 V at room temperature, and 0.21/0.43 V at 0 °C – both of which surpass most reported room-temperature results. Their energy efficiencies (84.6%/86.8%) at 0 °C even approach their room-temperature counterparts (93.9%/92.3%). Mechanistic studies reveal photoelectric/photothermal dual-promoted bidirectional oxygen catalysis responsible for intriguing performance.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":"31 1","pages":""},"PeriodicalIF":29.4,"publicationDate":"2025-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143477925","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As tumor-specific and tumor-associated antigens generally cannot be identified until after a tumor has already been established, these vaccines must be applied therapeutically when strong immunosuppressive mechanisms are already in place. Building upon previous work using cell membrane coating nanotechnology, the development of a broad-spectrum prophylactic cancer nanovaccine that consists of induced pluripotent stem cell (iPSC) membrane coated around an adjuvant-loaded nanoparticle core is shown. The resulting nanostructure is capable of presenting iPSC-derived oncofetal antigens, which are oftentimes re-expressed on cancer cells but lowly present on normal adult tissues. When administered in vivo, the iPSC membrane-coated nanoparticles are highly immunostimulatory and elicit strong antitumor immunity that can successfully inhibit the growth of multiple tumor types, including five different murine tumor models and in a bilaterial heterogeneous tumor model.

Integrated differential phase contrast imaging with scanning transmission electron microscopy revealed the creation of spiro interstitials in graphite by the irradiation.

However, the liquid-solid-liquid transition during the electrochemical reactions can disrupt the solid electrolyte interphase (SEI) and damage the structural integrity, ultimately limiting the cycling stability. Here, hierarchical-structured reduced graphene oxide coated eutectic gallium-indium liquid metal particles (RGO@EGaIn LMPs) are synthesized using a facile self-assembly strategy. The customized RGO@EGaIn electrode demonstrated impressive performance in both half-cell and full-cell configurations for LIBs. The morphological and phase transitions of RGO@EGaIn LMPs during the lithiation/delithiation processes are uncovered by real-time in situ transmission electron microscopy tests. It is clarified that the presence of RGO in the hierarchical structure buffers the volume expansion of LMPs from ≈160% to 125% and provides a fast pathway for the rapid transfer of ions and electrons during the electrochemical reaction, which effectively enhances the electrochemical performance of the electrode.

Electrochemical measurements show that, relative to Ni-CCP, Ni-CCPA exhibits appreciably higher performance toward alkaline oxygen evolution reaction (OER). Both the experimental results and theoretical simulations unravel that the improved OER performance of Ni-CCPA arises from the accelerated OH<sup>−</sup> diffusion within its porous architecture and enhanced OH<sup>−</sup> concentration near its highly exposed active sites at its high-curvature surfaces with localized electric fields.
