However, low-cost, carbon-based sorbents generally show insufficient water uptake in arid environments. We introduce a bulk activation strategy to synthesize carbon-based sorbents, incorporating KOH during the polycondensation of resorcinol-formaldehyde (RF). This approach utilizes the basic environment to promote a homogeneous distribution of the activating agent throughout the precursor, yielding BET surface areas and pore volumes up to 1704 m²g⁻¹ and 0.65 cm³ g⁻¹, respectively. XPS shows bulk-activated samples retain more surface oxygen (13.4–17.7 at%) than conventionally surface-activated carbons (9 at%). The activation route governs surface chemistry, the KOH/C ratio dictates porosity, and activation temperature affects both. Bulk-activated sorbents exhibit earlier adsorption onset and kinetics. Sorbents treated at 500°C with a 4.5 KOH/C ratio delivered the best performance under arid conditions (10%–30% relative humidity), with a daily water yield of 15–18 L kg⁻¹day⁻¹, while the same sample activated at 600°C performed best at 60% RH, reaching 23 L kg⁻¹day⁻¹ at a low regeneration temperature of 30°C. Sorbent performance remained stable for 400 h of cycling. These results establish bulk activation as an efficient strategy for tailoring porous carbon sorbents for SAWH across diverse humidity conditions.</p>","PeriodicalId":115,"journal":{"name":"Advanced Materials Interfaces","volume":"13 18","pages":""},"PeriodicalIF":4.5,"publicationDate":"2026-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/admi.70645","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149029143","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Plant-based materials offer a promising solution due to their biodegradability and sustainability. In this study, we developed highly water-repellent coatings using treated pine and palm pollen. Superhydrophobicity was achieved by integrating a hydrophobic plant-based wax with a micro-scale rough structure formed by the pollen. To enhance their surface chemistry, the two pollen species underwent acid treatment, which effectively removed proteins and altered the wettability of the sporopollenin-based structures. The modified pollen was then combined with two plant-based waxes, carnauba and soybean, to fabricate the final coatings. The resulting surfaces demonstrated remarkable water repellence, achieving the highest water contact angles of ∼158° and sliding angles of &lt;6° with the pine pollen/carnauba wax formulations. In contrast, the palm pollen/carnauba wax formulations achieved the highest water contact angle of ∼151° and sliding angle of 13°.

Inspired by this natural design, we developed mechanically robust structural color coatings applicable to flexible and curved substrates based on the keratin–melanin complex. A sulfonated keratin (s-keratin) aqueous solution forms a thin film upon solvent evaporation. Melanin particles synthesized using polydopamine—a melanin-mimetic polymer—were dispersed in the s-keratin-containing solution, which was then coated onto a substrate. After solvent evaporation, melanin particles formed an amorphous structure within the keratin matrix when the s-keratin concentration exceeded a certain threshold, generating an angle-independent structural color. Diverse functional groups of keratin contributed to interparticle and substrate adhesion, thereby yielding mechanically robust coatings, without requiring additional binders, crosslinkers, or complex fabrication processes.

However, OLEDs using thermally activated delayed fluorescence (TADF) emitters show a remarkable increase in electroluminescence up to one order of magnitude, depending on the applied voltage, as temperature climbs from 18 to 50°C. This work reveals that this heat-induced boost in TADF-OLED performance is also influenced by the device's active area. By varying the active area from 225 to 4 mm², we show that the thermal enhancement in both electroluminescence and external quantum efficiency (EQE) noticeably declines in smaller devices, with the smallest device showing performance deterioration at high temperatures. While large-area devices demonstrate up to a tenfold increase in EQE near the turn-on voltage due to heating, their EQE remains low compared to smaller devices, with heat only partially bridging this gap. The size-dependent behaviour is linked to factors like interface non-uniformity and aging in large areas, making these devices prone to burnouts that further worsen with thermal runaway. Since OLED performance often decreases with larger sizes, the ability of heating to mitigate this effect supports the effective use of large displays at higher temperatures and suggests TADF-OLEDs can convert waste heat into light efficiently.</p>","PeriodicalId":115,"journal":{"name":"Advanced Materials Interfaces","volume":"13 18","pages":""},"PeriodicalIF":4.5,"publicationDate":"2026-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/admi.70655","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149027728","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
