Calcium halide solutions (CaCl₂, CaBr₂, CaI₂) at pH 10.5 form hexagonally close-packed Ca²⁺ structures with spacings of 3.6–3.8 Å (CaCl₂), 4.8 Å (CaBr₂), and 5.0–5.1 Å (CaI₂). The CaCl₂ spacing matches the Cl^– diameter, suggesting direct Ca²⁺–Cl^– contact, whereas Br^– and I^– systems show consistent 0.7–0.9 Å offsets above their ionic diameters, indicating partially hydrated states. This behavior reflects the balance between ionic charge density and hydration effects. The high charge density of Cl^– enables strong Ca²⁺ interactions sufficient to displace hydration waters, while the lower charge densities of Br^– and I^– lead to less strong attractions with Ca²⁺ and partial hydration layers are preserved. These findings demonstrate how ion size and hydration control Stern layer ion organization, providing new insights into the electrical double layer structure.","PeriodicalId":62,"journal":{"name":"The Journal of Physical Chemistry Letters","volume":"13 1","pages":""},"PeriodicalIF":6.475,"publicationDate":"2025-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144192896","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}

Moreover, it is contributing to increased wildfires, which pose a distinct threat to cardiovascular and respiratory health, especially in the presence of other stressors. Living conditions can be a significant nonchemical stressor that alters physiology and impacts wildfire smoke responsiveness, especially when combined with ambient heat. To determine the combined impact of housing and temperature on behavioral health and the cardiopulmonary response to wildfire smoke (WS), female mice were split into enriched (EH) and depleted housing (DH) at normal (NT) and high temperatures (HT) for 20 weeks and assessed at baseline and after a single filtered air (FA) or WS exposure. Separate radiotelemetered mice were similarly housed for 4 weeks and then exposed to FA sham and then WS. EH mice had higher activity and body temperature and lower heart rate at NT, and these effects were blocked at HT. HT-DH mice had an increased heart rate variability following WS and increased arrhythmias. Interestingly, HT-EH caused increased anxiety-like behavior. Thus, although EH likely protects cardiopulmonary health, it might also negatively impact the behavior at HT in mice. As such, the living temperature and housing conditions should be carefully considered when assessing susceptibility to disease and environmental exposures.","PeriodicalId":36,"journal":{"name":"环境科学与技术","volume":"11 1","pages":""},"PeriodicalIF":9.028,"publicationDate":"2025-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144193214","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the mechanisms driving antibiotics-induced nanoplastics aggregation under environmentally relevant conditions remain unclear. This study investigated the effects of ciprofloxacin (CIP) and sulfamethoxazole (SMX) on the aggregation of four environmentally relevant nanoplastics (pristine and aged polystyrene, polyethylene, and polypropylene). At pH 5.0, both CIP and SMX significantly promoted nanoplastics aggregation, with CIP being more potent. CIP enhanced nanoplastics aggregation through charge shielding driven by electrostatic attraction, hydrogen bonding (HB), and charge-assisted HB (CAHB), whereas SMX promoted aggregation solely through molecular bridging involving HB and CAHB. At pH 7.0, only CIP facilitated aggregation, while neither antibiotic induced aggregation at pH 9.0. Aged polystyrene aggregated more readily than pristine polystyrene due to increased surface functional groups. Polyethylene and polypropylene showed weaker aggregation due to fewer surface functional groups. High organic matter (OM) levels (1.65 mg/L TOC) inhibited antibiotics-induced aggregation, whereas low OM levels (16.5 μg/L TOC) were more conducive. These findings highlight that antibiotic characteristics, pH, OM levels, plastic types, and environmental aging collectively influence nanoplastics aggregation, and improve the understanding of the fate and risk of nanoplastics in natural waters.","PeriodicalId":36,"journal":{"name":"环境科学与技术","volume":"7 1","pages":""},"PeriodicalIF":9.028,"publicationDate":"2025-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144193220","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, we demonstrate the viability of vapor transport deposition (VTD), a solvent-free processing method, to realize polycrystalline films of both lead iodide (PbI₂) and methylammonium lead iodide (MAPbI₃) perovskites showing preferential crystallographic orientation. Notable is the difference in perovskite film texturing observed for sequentially and co-deposited VTD films of MAPbI₃, as well as the lack of strong preferential orientation in solution-processed MAPbI₃ films. While sequential deposition of the perovskite precursors PbI₂ and methylammonium iodide (MAI) leads to a MAPbI₃ film with a limited preferential grain orientation, co-deposited MAPbI₃ films mirror the orientation of excess PbI₂ present in the film. The latter is confirmed by the similar dependence of preferential orientation for PbI₂ and co-deposited MAPbI₃ on underlayer roughness, as well as the emergence of preferential orientation in MAPbI₃ only when excess PbI₂ is present. Both MAPbI₃ and PbI₂ films show a strong preferred lattice orientation on smooth substrates, while on rougher substrates, this orientation is disrupted. These results are interpreted as excess PbI₂ frustrating the diffusion of MAI in the film, which would otherwise disrupt the preferred orientation, pointing to a notable difference in lattice orientation arising from processing technique and conditions.","PeriodicalId":61,"journal":{"name":"The Journal of Physical Chemistry C","volume":"74 1","pages":""},"PeriodicalIF":4.126,"publicationDate":"2025-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144192899","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recent advancements in OER demonstrate that inducing spin-polarization at the anode either employing chiral molecular modification or magnetic substrate, augmentation of OER is possible. Adopting this idea, we evaluated the effect of chiral molecular modification of mixed-transition metal-based spinel oxide on the spin-polarized charge transfer during OER. Chiral molecular functionalization of the catalyst has been carried out using chiral analogs of phenylalanine, which enhances the stability and catalytic activity of the catalyst by controlling the electron's spin utilizing the chiral-induced spin selectivity (CISS) effect. The experimental results show that the chiral molecule integrated catalyst decreases the overpotential by ∼200 mV at 10 mA cm^-2 with respect to the achiral one. Moreover, it increases the current density by ∼2 times at 2.1 V (vs. RHE) and decreases hydrogen peroxide production significantly compared to its achiral analog. The results of these studies are explained by controlling the spin-polarization of the anodic current during water oxidation employing CISS effect.
