Among the many hole transport materials, inorganic materials are favored because of their remarkable cost effectiveness, chemical stability, and long-term stability. Although NiO_<i>x</i> is preferred in inorganic hole transport layer material due to its excellent performance, its high reactivity with the perovskite interface may lead to interface defects and carrier recombination, affecting the long-term stability of the device. To further enhance both the performance and long-term stability of perovskite solar cells, the effect of environmental relative humidity on the performance of NiO_<i>x</i> films was discussed in this study. By comparing and analyzing the surface morphology and physical properties of NiO_<i>x</i> films prepared under different humidity conditions, we found that relative humidity has a significant effect on the performance of NiO_<i>x</i> films and their prepared perovskite solar cells. In particular, NiO_<i>x</i> films prepared at 60% relative humidity and fabricated into perovskite solar cells exhibited a significantly higher short-circuit current density (<i>J</i>_sc) and fill factor (FF). These findings provide an important reference for optimizing the preparation process and enhancing the performance of perovskite-based solar devices.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"32 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144211672","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, their development is hindered by dendrite formation and complex anodic side reactions. In this study, a binder-free zirconium-based metal–organic framework (MOF) membrane, NUS-8, is proposed as an artificial solid electrolyte interphase (ASEI) for the Zn anode, with the aim to regulate Zn²⁺ desolvation and deposition processes, inhibit dendrite growth, and mitigate anodic side reactions. The microporous structure and abundant functional groups (–COOH, –OH) in the NUS-8 membrane enable ion flux control through an ion-confinement effect, reducing ion transfer resistance and providing stable pathways for Zn²⁺ migration. These characteristics enhance the hydrophilicity of the Zn anode surface, accelerate the desolvation process, and lower the activation energy barrier for Zn²⁺ migration from 28.73 to 26.10 kJ mol^–1. As a result, symmetric cells with NUS-8@Zn anodes exhibited a prolonged lifespan exceeding 1180 h at 1 mA cm^–2 and 1 mAh cm^–2, significantly outperforming bare Zn anodes (90 h). Additionally, the NUS-8@Zn||MnO₂ full cell demonstrated excellent cycling stability, with a capacity retention of 72.3% over 3000 cycles at 5 A g^–1. This work presents a promising strategy to enhance Zn anode performance and introduces a design approach for advancing AZIBs.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"51 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144218949","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}

This concept has been extended to two-dimensional (2D) van der Waals materials, including transition metal dichalcogenides (TMD), which exhibit promising applications in electrocatalysis. In this work, we have explored the synthesis of entropy mixture crystals (TMD_mix) involving the chemical vapor transport of five individual elements, Mo and W as metal elements, S, Se, and Te as chalcogenide elements, resulting in a crystalline structure with a controlled composition Mo_0.56W_0.44(S_0.33Se_0.35Te_0.32)₂, with an estimated Δ<i>S</i>_mix of 0.96<i>R</i>. When observed along the [001] zone axis, STEM HAADF images indicate the presence of the different crystal phases of the 2D TMDs (1T, 2H, and 3R). Our findings demonstrate the potential of the entropy TMD_mix materials as catalysts for the hydrogen evolution reaction, offering an alternative to noble metal-based catalysts. To maximize the potential of TMD_mix, we chose chemical exfoliation with the resulting material being subdivided into size groups, big and small, according to their lateral size. In an acidic medium, the lowest overpotential of 127 mV and a Tafel slope of 79 mV/dec were obtained for the exfoliated sample with a small lateral size (exf-TMD_small).","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"102 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144218950","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}

By comparing CIPS with and without the nonferroelectric (NFE) phase, we observed unexpected stability of the domain framework at high temperatures. This was evidenced by in situ temperature-dependent PFM measurements and Raman spectra. STEM analysis revealed Cu ion defects and charge accumulation at the FE/NFE interface, which contributed to the thermal stability due to a strong pinning effect.

However, the emission modulation by changing the organic group has been rarely reported. Herein, Cs⁺ in Cs₂ZrCl₆:Sb³⁺ was substituted by a series of organic groups. The substitution by butyltriphenylphosphonium (BTP) generated a monoclinic crystal with a <i>P</i>2₁/<i>n</i> space group, which was determined by single-crystal diffraction. (BTP)₂ZrCl₆:Sb³⁺ features typical dual-band emissions from self-trapped excitons. Moreover, because of the large distance (&gt;11 Å) among the [ZrCl₆]^2– octahedra, more Sb³⁺ dopants can be tolerated before concentration quenching. Consequently, (BTP)₂ZrCl₆:Sb³⁺ exhibited high inner and external quantum efficiencies of 96.2 and 73.5%, respectively. Furthermore, the butyl group of BTP was changed to other groups with different sizes and electronic states. The small change of the organic group can effectively tailor the emission intensity (<i>I</i>_maximum/<i>I</i>_minimum = 7.06 ± 0.08) and wavelength (615–665 nm). The applications of (BTP)₂ZrCl₆:Sb³⁺ in white light-emitting diodes (WLEDs) and anticounterfeiting were demonstrated.

Elemental selenium was successfully supported on upconversion nanoparticles (UCNPs) to constitute the near-infrared (NIR) light-responsive UCNP@Se heterostructures for the first time. Under 980 nm irradiation, the UCNP@Se heterostructures could not only produce holes and superoxide radicals •O₂^– but also catalyze the generation of hydroxyl radicals •OH by highly elevated levels of H₂O₂ in tumor cells to kill the tumor cells. In addition to the superior photocatalytic performance, elemental selenium itself also exhibited inherent inhibition activity against tumor cells. On the basis of the binding of anthracycline anticancer drugs such as doxorubicin (DOX) to the supported elemental selenium through Cu²⁺ bridging coordination, the UCNP@Se–Cu-DOX drug delivery system was constructed. The introduction of Cu²⁺ not only improved the efficient loading of DOX but also achieved the “AND” logic-controlled release of DOX under the combined stimuli of low pH and overexpressed glutathione (GSH) in tumor cells. Moreover, the loaded Cu²⁺ reacted with the overexpressed GSH to generate the active species Cu^II-GSSG upon NIR light irradiation, which further promoted tumor cell apoptosis. The NIR light-responsive UCNP@Se–Cu-DOX drug delivery system achieved the combination tumor therapy of selenium therapy, photocatalytic therapy, and logic-gated chemotherapy and has great potential applications in tumor therapy.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"135 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144218955","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}

Here, a simple but effective approach was demonstrated to synthesize highly stable red CsPbI₃ QDs by introducing a multifunctional molecule, phenformin hydrochloride (PhenHCl), as an additive ligand. While the biguanide functional group in PhenHCl formed multiple hydrogen-bond interactions with the lead halide octahedron, the excess Cl^– anions compensated for the iodine vacancies and eliminated trap states in the CsPbI₃ QDs. The synergistic effect of the biguanide functional group and halogen compensation significantly passivated surface defects of the red CsPbI₃ QDs, yielding a photoluminescence (PL) quantum yield of 98.6% and excellent ambient stability with 90% PL intensity retention over 80 days.

This type of Janus bilayer aerogel was successfully fabricated with a hydrophobic upper layer comprising a poly(vinyl alcohol) (PVA)/chitosan (CS)/carbon black (CB) composite aerogel and a hydrophilic lower layer based on a PVA/CS/phase-change microcapsule composite aerogel. With such a Janus bilayer structure, the composite aerogel demonstrates efficient light absorption and superior salt-resistant performance by its upper layer and prominent latent heat-storage and water-transport abilities by its lower layer. More importantly, the introduction of phase-change microcapsules enables the lower layer of the developed bilayer aerogel to store photothermal energy absorbed by its upper layer, continually driving interfacial evaporation under insufficient solar irradiation conditions. Benefiting from these advantages, the developed composite aerogel-based evaporator shows a high evaporation rate of 2.23 kg m^–2 h^–1 under one-sun irradiation alone with good resistance to salt accumulation. Compared to a control evaporator without any phase-change microcapsules, the developed evaporator obtained an increase in the total mass change of 150% under dark conditions. Meanwhile, a thermoelectrical generator equipped with the composite aerogel exhibits an open-circuit voltage of 143.89 mV under one-sun irradiation alone with an elongated power output period of 30 min. With an innovative Janus bilayer structural design by combining a biodegradable PVA/CS aerogel with phase-change microcapsules and CB nanoparticles, this study represents a significant advancement in renewable energy utilization, particularly in sustainable water purification and hybrid energy systems. The developed Janus bilayer composite aerogel exhibits great application potential in highly efficient freshwater production and electricity generation under intermittent sunlight irradiation.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"52 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144211674","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}
