Rapid progress in PSCs has largely been fueled by innovations in device architecture and component optimization. Among these, the interface between the hole transport layer (HTL) and the perovskite layer is crucial, as it not only facilitates efficient hole extraction and transport but also protects the perovskite from environmental degradation. This review highlights recent advancements in engineering this critical interface, focusing on improvements in surface morphology, interface adhesion, energy level alignment, and defect passivation. Special attention is given to the roles of amide, carboxylic acid, phosphonic acid, and halogenide groups in enhancing HTL properties at the perovskite interface. By synthesizing the latest research and experimental insights, this review provides a comprehensive overview of surface passivation’s contributions to high-performance PSCs. It also discusses future directions and challenges in optimizing this interface, key to further advancing this promising photovoltaic technology.","PeriodicalId":50,"journal":{"name":"Langmuir","volume":"36 1","pages":""},"PeriodicalIF":3.9,"publicationDate":"2025-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144165727","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Researchers are exploring a range of sustainable cleanup solutions, such as using heating components to reduce oil viscosity. Herein, an electroless plating technique was adopted for depositing copper sulfide (CuS) on a polyurethane (PU) sponge by a coordination strategy. Subsequently, a layer of octadecyltrichlorosilane (OTS) was deposited to enhance the surface oil absorption ability. The PU@OTS-CuS sponge has demonstrated superhydrophobicity and remarkable oil absorption capability ranging from 11.5 to 47 g/g for oils with diverse viscosities. Moreover, it has sustained its 22.5 g/g oil absorption capacity for lubricant oils and separation efficiency of over 97% for the n-hexane and dichloromethane–water mixture even after undergoing 10 cycles. The surface temperature of the modified sponge was increased to 74 °C within 180 s under 1 sun irradiation and a sustained crude oil absorption capacity of 20 g/g even after 10 cycles. In continuous crude oil remediation, the modified sponge collected 3.257 g within 15 min at a rate of 0.542 g/min. Additionally, the modified sponge revealed superior stability against immersion in seawater and different pH solutions, exposure to UV light, sand abrasion, mechanical compression, and cyclic photothermal performance. This research presents a new strategy for depositing a photothermal component on sponge surfaces to improve crude oil cleanup.","PeriodicalId":50,"journal":{"name":"Langmuir","volume":"147 1","pages":""},"PeriodicalIF":3.9,"publicationDate":"2025-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144165729","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Wood, a plentiful and ecofriendly natural material characterized by a hierarchical porous architecture, robust mechanical strength, and abundant functional groups, has been adopted as an adsorptive filter for water purification. However, the mechanism of natural wood filters for removing pollutants from water has not been analyzed. In this study, we prepared three wood filters (balsawood, basswood, and Chinese fir) with different pore structures for the removal of the tetracycline (TC) antibiotic. We systematically investigated the structures and properties of the three wood filters to establish clear structure–property-performance relationships. By comprehensively considering the flux and TC removal efficiency, we selected the basswood filter as the optimal filter and further discussed the removal efficiency of the basswood filter and its removal mechanism for TC. When using five basswood filters, after continuously treating 120 mL of 0.5 mg L–1 TC solution at 5000 L m–2 h–1, a relatively high removal efficiency of over 85% could still be achieved. The filters retained ∼80.5% of their removal efficiency after five regeneration cycles, demonstrating excellent reusability. The further studies prove that there are three primary interaction forms in the process of TC removal by the basswood filter, which are electrostatic interaction, hydrogen bonding interaction, and π-π interaction. This is expected to be widely applied in actual wastewater treatment.","PeriodicalId":50,"journal":{"name":"Langmuir","volume":"1 1","pages":""},"PeriodicalIF":3.9,"publicationDate":"2025-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144165738","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By combining atomistic molecular dynamics (MD) simulations with experimental validation, we examined the influence of pH, uranyl ion concentration, and dendrimer generation on the adsorption behavior. Our study revealed that uranyl ion adsorption was greater when PAMAM was grafted onto graphene/CNT than when PAMAM was grafted onto pristine PAMAM. However, PAMAM-grafted CNTs exhibited superior adsorption capacity at specific uranyl concentrations due to their curvature and abundant accessible binding sites. Higher-generation PAMAM dendrimers grafted onto graphene/CNTs exhibited a greater adsorption capacity due to the increased availability of binding sites, which is consistent with experimental observations. The adsorption capability for uranyl ions in all four generations of the PAMAM dendrimer increased as the concentration of uranyl ions increased. The adsorption capacity increased with increasing uranyl ion concentration, and adsorption occurred on both PAMAM and graphene/CNT surfaces, with saturation observed at higher concentrations. This study provided insights into the adsorption mechanisms and highlighted the potential of PAMAM-based nanocomposites for efficient uranyl ion extraction and environmental remediation.","PeriodicalId":50,"journal":{"name":"Langmuir","volume":"65 1","pages":""},"PeriodicalIF":3.9,"publicationDate":"2025-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144165775","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Based on the results of active species trapping experiments and X-ray photoelectron spectroscopy, it was confirmed that an S-scheme heterojunction formed between Ag2WO4 and CuBi2O4, which effectively promoted the separation of electron–hole pairs and significantly enhanced the sonocatalytic performance of CuBi2O4. Cyclic experiments further demonstrated that the Ag2WO4/CuBi2O4 composite catalyst possessed excellent reusability and stability.

In this context, a cobalt (Co) doping strategy was proposed to improve the H2S-sensitive properties of In2O3 nanomaterials, enabling them to monitor 1 ppm of H2S at a relatively lower temperature. The Co-doped In2O3 hierarchical porous nanocubes (Co–In2O3 HPNCs) were prepared through a hydrothermal route using In(OH)3 as a precursor. When utilized as a sensing material to detect H2S, the Co–In2O3 HPNCs demonstrated significant enhancements compared to pure In2O3. These enhancements include a reduction in the operating temperature (260 vs 300 °C), a significant increase in response (36.99 vs 12.28 for 20 ppm of H2S), and better selectivity (13.21 vs 3.07 times to ethanol). Even to 1 ppm of H2S, the Co–In2O3 sensor can give a response value of 1.86, highlighting its substantial potential for detecting H2S at the limit of detection (LOD) of 1 ppm. A detailed analysis of the multiple sensitization effects of Co doping reveals that these improved H2S sensing characteristics of Co–In2O3 HPNCs can be primarily traced back to three factors, namely, an increased oxygen vacancy concentration, a narrowing of the bandgap, and an upward shift of the Fermi level.","PeriodicalId":50,"journal":{"name":"Langmuir","volume":"172 1","pages":""},"PeriodicalIF":3.9,"publicationDate":"2025-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144165736","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Under the synergistic effect of the confinement at the Fe–Al2O3 interface, the fabrication of small Fe nanoparticles is accomplished. The results indicate that the catalytically active Fe nanoparticles have a diameter of approximately 10 nm, and the grown CNTs have a diameter of approximately 15 nm. Based on the systematic characterization results, the nonactive Fe2O3 clusters confined by strong interfacial interaction induce multiple nucleation of Fe on their surface during multiple loading processes, facilitating the formation of nanoparticles.

Proteins in solution can adsorb onto and denature at both solid–liquid and gas–liquid interfaces, and the spontaneous adsorption of proteins on a nanoparticle (NP) surface to form a corona can be described as a specific case of adsorption at the solid–liquid interface, where the surface curvature also becomes important. While nanoparticles offer a large surface area, they are not the only surface in the sample with which the proteins interact due to the creation of other interfaces in an experimental setup. In this work, we examine the role of the air–water interface in protein denaturation via soft corona studies with citrate-capped gold nanoparticles. Chymotrypsin (ChT) protein in the soft corona was observed to exhibit an inverse relationship between concentration and denaturation, an air–water interface-mediated trend that, without the right control experiments, can be misinterpreted to be caused by protein–NP interactions. We show that any protein denaturation observed comes from the synergistic effect of the air–water interface and agitation and that NPs did not denature ChT in the “soft corona” in the absence of these two factors. While the propensity to adsorb and denature at hydrophobic interfaces varies among proteins with different structural properties, it is important to use simplified procedures that minimize interfacial areas other than the nanoparticle surface in corona studies to prevent misattribution of the observed effects.","PeriodicalId":50,"journal":{"name":"Langmuir","volume":"2 1","pages":""},"PeriodicalIF":3.9,"publicationDate":"2025-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144165733","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The formation of a Ti(IV)-DFOB complex in solution is evident from electrospray ionization mass spectroscopy. Dissolved Ti was analyzed by UV/visible and inductively coupled plasma optical emission spectroscopy and was found in the micromolar range (ca. 1–60 μM) over days. At all pH values, dissolution is more extensive for food-grade NP than for anatase and rutile. Near neutral pH, Fourier transform infrared spectroscopy (FTIR) data suggest that siderophore adsorption is more prominent than Ti dissolution. Scanning electron microscopy data reveals erosion of the TiO2 surface with DFOB. A comprehensive kinetic profile supports multiple dissolution steps associated with anatase and rutile, with fewer steps for food-grade NPs. The addition of small organic acids shows mostly synergistic effects toward dissolution.
