However, fabricating all-solution-processed perovskite LEDs (PeLEDs) remains challenging because the perovskite emitters are susceptible to damage from subsequent solution layers. Here, we introduce a novel fabrication method that employs a low-pressure-treated electron-transport layer (ETL) at room temperature, complemented by a polyethylenimine (PEI) interface modification layer. Notably, the optimized PEI-modified CsPbBr3 exposed to air exhibits a remarkable 3-fold increase in photoluminescence intensity and maintains nearly constant light output for over 100 h, compared to pristine perovskite. Crucially, the incorporation of PEI significantly reduces the electron-transport barrier, mitigates the degradation of perovskite crystals caused by water and oxygen, and minimizes adverse interactions with solvents from the subsequent ETL. As a result, all-solution-processed PeLEDs incorporating an ETL subjected to a 20 min low-pressure treatment at 1 × 10–1 mbar at room temperature achieved an unprecedented external quantum efficiency of up to 4.6%, a record low turn-on voltage of 2.1 V for CsPbBr3, and an operational lifetime approximately 5 times longer than that of conventional devices. This strategy, both conceptually straightforward and easy to implement, offers a new avenue for the development of future printable PeLEDs.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"210 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143495730","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}

Therefore, the development of unique, efficient, and cost-effective bifunctional electrocatalysts, which can perform both hydrogen evolution reaction (HER) and oxygen evolution reaction (OER), is critical for the accessible utilization of renewable energy. The increasing overall efficiency of the water-splitting reaction is pivotal for sustainable energy conversion and hydrogen production. Herein, we present a facile solution-based synthesis route to control the crystallinity of the cobalt tungstate (CoWO4) nanomaterials to amorphous, semiamorphous, and crystalline phases and further exploit these nanomaterials as bifunctional electrocatalysts for the HER, OER, and overall electrochemical water splitting reaction. Notably, the semiamorphous cobalt tungstate nanomaterials show a remarkable surface area of approximately 150 m2/g, the highest reported for CoWO4-based materials, and demonstrated superior activity for both the OER and HER and outstanding stability over the amorphous and crystalline counterparts.

However, the regulation and design of advanced sodium storage structures are limited by their diverse and complex microstructures. Herein, diammonium phosphate (DAP) as a cross-linking agent for corn starch and modification of the physicochemical properties of the starch surface can effectively promote the regulation and balance between the pore structure and interlayer spacing of the constructed HC. The electrochemical performance of modified HC generally outperformed that of unmodified HC samples. Specifically, the optimized HC-10 achieved an improved reversible capacity (344.16 mAh g–1 at 0.03 A g–1), optimal rate capability (134.73 mAh g–1 at 0.3 A g–1), and enduring cycle life (capacity retention of 98.5% after 500 cycles at 0.3 A g–1). The superior performance of HC-10 originated from the optimal modification operation of DAP for corn starch, resulting in a balance between the formation of disordered phases and pore structures. On the one hand, the DAP facilitates the growth of the carbon layers during pyrolysis and affects the microinterlayer structure of HC, while it also accelerates the decomposition of the precursor as a catalyst and releases gas phase products, which further modulate the defects and pore structures of HC. This work provides a reference for the microstructural regulation of HC, paving the way for the development of biomass-derived anode materials with exceptional charge/discharge performance.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"90 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143486603","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}

Hydrophobic Sol was modified with poly(ethylene glycol) to self-assemble into stable nanomicelles (SP). CHA could be encapsulated into the hydrophobic core of these nanomicelles, which increased its bioavailability greatly. Short peptide K (CKLVFFAED) was incorporated (CI@SPK) to facilitate their crossing the blood–brain barrier. Then, CI@SPK targeted the AD lesion area, and CHA was released in greater quantities with the help of IR780 under irradiation with an 808 nm laser, resulting in synergistically scavenging reactive oxygen species (ROS) with Sol. Consequently, the nanomicelles CI@SPK demonstrated capabilities in scavenging ROS, inhibiting β-amyloid (Aβ) aggregation, and eventually modulating microglia phenotype from M1 to M2 to promote Aβ phagocytosis and clearance.

To address this issue, in this study, a new pseudo-quaternary blend composed of conjugated block copolymer donors and acceptors, PM6-b-TT:b-PYT, is introduced as the active layer for all-PSCs. Compared to the all-PSC based on the traditional binary blend, PM6:BTTP-T, those based on pseudo-quaternary active layer exhibited significantly improved thermal stability after thermal annealing under harsh conditions of 150 °C in an ambient atmosphere. More importantly, to elucidate the morphological stability of the pseudo-quaternary active layer, visible evidence of the thin film’s surface and internal structure is carefully investigated by multiple advanced techniques. After extended thermal stress at 150 °C, the binary bulk heterojunction (BHJ) films exhibit excessive polymer chain aggregation, phase separation of the polymers, and increased surface roughness, forming bulk charge traps and increasing the exciton recombination. Meanwhile, the pseudo-quaternary BHJ films maintain the crystallinity and nanostructure of the active layer, improving the stability of the all-PSCs.

The incorporation of GeTe significantly optimized both carrier concentration and mobility, with the Cu2Se/5 wt % GeTe composite exhibiting a carrier mobility of 30.8 cm2·V-1·s-1, more than twice that of pristine Cu2Se (11.4 cm2·V-1·s-1). Additionally, the inclusion of GeTe substantially reduced both the electrical and lattice thermal conductivity across the entire temperature range. These improvements culminated in a peak ZT of 2.2 at 923 K for the Cu2Se/10 wt % GeTe composite.

Microfluidics is useful for constructing such photonic microobjects. The traditional method of injecting different colloidal photonic streams toward anisotropic multiple stopband photonic microobjects involves complicated and time-consuming procedures. Herein, an easy yet effective approach to fabricate Janus photonic microobjects with dual stopbands from a single stream of photonic components is proposed. A microfluidic device is used to prepare bullet-like, single-stopband photonic microobjects by virtue of the microchannel’s confinement effect. Both the size and shape are readily regulated by adjusting the flow rate of the continuous phase. Under the protection of the desired region of the photonic microobjects with polystyrene (PS) film or silicone tube, the other region is selectively etched to generate a new photonic part. The Janus photonic microobjects with dual stopbands are achieved thereby. Precision control of the protection position of the single-stopband photonic microobjects provides the flexibility to achieve photonic microobjects with various segmental combinations. The porous structure at the etched region is conducive to further functionalization, for example, fluorescence performance, by filling polymers. The resultant photonic microobjects with strong information-encoding characteristics are promising in display and anticounterfeiting.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"66 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143495734","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, achieving this efficient conversion would yield substantial cost advantages and hold immense potential for development. Here, we demonstrate the enhanced photocatalytic conversion efficiency of CH4 at room temperature and pressure conditions without requiring any oxidant through the construction of a bimetal Ag–Cu-loaded brookite TiO2 photocatalyst. The C1 products were ultimately obtained with 100% selectivity and a yield of 936 μmol·g–1·h–1. The performance exceeds that of similar research by tens of times. The high selectivity of this system is attributed to the optimal number of ·OH, which strikes a balance between excess and deficiency. Ag effectively enhances electron transport in the photocatalytic reaction process on a dual active site photocatalyst, while Cu significantly improves the selectivity of the C1 products. In this system, the hydroxyl radical (·OH) activates CH4 to generate the methyl radical (·CH3), which then binds with the lattice oxygen of TiO2, breaking the Ti–O bond and resulting in the formation of *OCH3. The *OCH3 undergoes further conversion to CH3OH, which is subsequently oxidized to HCHO by ·OH. This work presents a cost-effective and highly efficient approach for directly oxidizing CH4 into valuable chemicals, ensuring superior selectivity.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"25 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143495781","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}
