Prior research on gendered language has primarily focused on everyday conversations and workplace discourse. However, media interviews, where gender intersects with institutional roles and performative identities, remain understudied, particularly from the perspective of Conversation Analysis. This qualitative study addresses this gap by examining a 10-min segment from Will Smith’s Full Interview with Ellen. Using conversation analysis, supported by summative content and comparative analysis, the study explores how gendered speech patterns manifest in a media interview setting. The analysis focuses on five linguistic dimensions: lexical patterns, sentence complexity, assertiveness, interruptions and politeness, and turn-taking strategies. Findings confirm several established gendered language norms: the male speaker exhibits greater assertiveness, topic control, and frequency of interruptions, while the female speaker employs more facilitative, polite, and cooperative strategies. However, these patterns are shaped not only by gender but also by Ellen DeGeneres’s institutional role as host and her identity as an openly lesbian public figure. The study contributes to the understanding of how conversational dominance and linguistic politeness are co-constructed in media discourse. It highlights the need for more context-sensitive approaches to gender and language research, especially in mediated settings where identity, institutional roles, and audience expectations interact.

The humification behavior of lignocellulosic components ( i.e. , cellulose, hemicellulose and lignin) under acid-alkali two-step hydrothermal treatment was investigated with particular interest of revealing the contribution of single components as well as their interaction to hydrothermal humic acid (HHA). Lignin with its rich aromatic structures, had the highest HHA contribution (51.8 ± 1.0 wt%), while cellulose and hemicellulose only contributed 8.8 ± 1.6 wt% and 20.1 ± 4.4 wt% HHA yields, respectively. The conversion pathway of these components toward humification indicated that the hydrochar (HC) rather than the hydrothermal solution (HS) had higher humification capability under alkaline hydrothermal conditions because the hydrochar-derived HHA yields of 40.8 ± 2.0 wt% (cellulose), 66.2 ± 6.4 wt% (hemicellulose) and 55.4 ± 6.1 wt% (lignin) were achieved. In addition, co-hydrothermal treatment of cellulose, hemicellulose and lignin under this process improved the HHA production ascribing to the increased HC yield (23.1–53.1 %). The chemical characteristics of HHA products from lignocellulosic components (cellulose, hemicellulose, lignin) and their combinations were similar to the acknowledged natural humic acids. The hydrothermal humification of biowaste mainly passes through a top-down pathway ( i.e. , HHA forms from the oxidation of large fragments of hydrochar) as well as two bottom-up pathways ( i.e. , the soluble chemicals conduct the polymerization reaction for HHA production and react with the fragments from HC to synthesize the HHA). This study filled the lack of knowledge in the field of biowaste humification.

Traditional detection methods to detect heavy metal ions are time-consuming, complicated, and expensive. Here, we developed a simple electroless plating method to prepare three-dimensional gold nanowire (Au NW) films with high specific surface area. In an aqueous plating bath, tetrachloroauric acid, 4-dimethylaminopyridine and formaldehyde are used as precursor, ligand, and reducing agent, respectively. An electrochemical sensor based on a Au NWs/SPE could be applied for simultaneous detection of lead (Pb(II)), arsenic (As(III)), and mercury (Hg(II)) ions. The detection limits of Pb(II), As(III), and Hg(II) are 2.6, 1.5, and 4.2 μg L−1, all lower than the permissible limits of the WHO for drinking water (the permissible level of Pb(II) and As(III) is 10.0 μg L−1, and the permissible level of Hg(II) is 6.0 μg L−1), respectively. This work presents a simple and novel method to prepare gold nanowires for quick detection of trace heavy metal ions.

Children’s books play an important role in providing windows and mirrors to young people on a variety of academic content, social issues, and personal experiences. Numerous books introduce young people to the art museum. The text and illustrations of these books send messages about who belongs in museums as a visitor and what kinds of art are worthy of curation. Content analysis grounded in critical race theory and the right to the city reveals that museums are still portrayed as institutions that are based on White norms and culture, from the preponderance of visitors in the galleries to the art on the walls. Story lines illustrate how children’s race is connected to the alienation and escape, interaction with art, enjoyment, and identification that children experience when visiting the art museum.

Even though membrane separation materials have worked very well for purifying dyestuff wastewater, the short residence time and high pollutant flow rates in the membrane, which can lead to incomplete or insufficient photodegradation, make it currently difficult to separate and photodegrade large-scale or highly concentrated dyestuff wastewater in one step. Herein, we propose an ‘all-in-one’ 3D nanofibrous aerogel architecture (aPAN/MXene@Ag–Ag2S), which can achieve efficient purification of high-concentration dyeing effluents under natural sunlight via two methods: filtration or solar interfacial evaporation. Ag–Ag2S nanoparticles with two different structures are reduced on Ti3C2Tx nanosheets through a UV light-induced in situ reaction, and they function as effective photocatalysts with excellent photothermal ability for solar interfacial evaporation. The special combination of Ag–Ag2S, MXene, and aPAN nanofibers in the aPAN/MXene@Ag–Ag2S aerogels achieved 95% separation and 99.99% photocatalytic degradation efficiencies for oil/water emulsions with methylene blue at a high concentration of 1000 mg L−1, which far exceeds those of recently reported MXene-based catalysts. In particular, wastewater from industrial dyeing could be treated to clean water under natural sunlight. In addition, the evaporation rates of the aPAN/MXene@Ag–Ag2S aerogel for seawater and textile dye wastewater respectively reach 2.69 kg m−2 h−1 and 2.44 kg m−2 h−1 and almost 100% degradation efficiency is achieved. Both the filtered fresh water and the evaporated water produced by solar evaporation meet the requirements of the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant or the World Health Organization (WHO) and the US Environmental Protection Agency (EPA) standards for drinking water, respectively.

With the extensive application of nanotechnology, metal nanoparticles (MNPs) have been widely used, thus are universally detected in the environment. This has caused increasingly concerns due to their toxicity and the potential health risks they pose to humans. In this work, the concentrations and particle size distributions of MNPs and concentrations of associated metal ionic species in shellfish seafood (clams and oysters) were investigated using single particle inductively coupled plasma mass spectrometry (sp-ICP-MS) and inductively coupled plasma mass spectrometry (ICP-MS). The MNPs in the clam and oyster tissues were extracted via an alkaline digestion method with a recovery rate of 95.9% (for gold nanoparticles (AuNPs)). Then total concentrations of 41 metal elements were measured in the two types of seafood, of which 20 were selected for sp-ICP-MS analysis. The results showed that 5 types of MNPs were detectable in clams (Y, La, Ce, Pr, Gd) and 5 types of MNPs were detectable in oysters (Y, La, Ce, Pr, Nd). Size distributions of MNPs in clams and oysters were in the range of 35–55 nm and 30–65 nm, respectively. Nanoparticle concentrations in clams and oysters ranged from 0.6 to 37.7 ng/g and 4.2–19.7 ng/g, and accounted for 3.4%–50% and 5.5%–46% of the total metal content, respectively. Based on this analysis, the health risks of metals in the two kinds of seafood were evaluated by comparing the Provisional Tolerable Weekly Intake (PTWI) with limits recommended by the World Health Organization (WHO)/Food and Agriculture Organization (FAO). These results provide important information about the presence of metal nanoparticles in seafood and, to the best of our knowledge, this is the first time that the nanoparticles of rare earth elements have been detected and reported in bivalve mollusc tissues.

Arsenic pollution in natural water is a worldwide problem. In this work, a resin-based hydrated iron oxide (D303-HFO) adsorbent was designed to remove arsenate (As(V)) and arsenite (As(III)) in the groundwater. The structure and morphology of the D303-HFO adsorbent were characterized by FTIR, XRD , SEM and TEM tests. The specific surface area, pore volume and pore size increased with the incorporation of HFO nanoparticles in the resin. In addition, the effects of pH and coexisting ions on the arsenic removal efficiency were investigated. Results indicated that the D303-HFO had efficient removal performance for arsenic in the pH range of 3–9 and showed high selectivity for As(V) and As(III) under the influence of competitive ions. The adsorption kinetics study confirmed that the adsorption process was dominated by chemisorption , and the adsorption isotherms of As(V) and As(III) by D303-HFO fitted the Langmuir model. Thermodynamic parameters indicated that the adsorption reaction was spontaneous and exothermic. Moreover, the regeneration and stability experiment indicated that the D303-HFO adsorbent was super reusable after five consecutive cycles and could be put into service stably and permanently. The fixed-bed column test showed that the water sample containing As(V) and As(III) was treated with a volume of 900BV and 1100BV, respectively. After the treatment, the effluent concentration reached the drinking water standard stipulated by WHO.

Lead halide perovskite has demonstrated remarkable potential in the wearable field due to its exceptional photoelectric conversion capability. However, its lead toxicity issue has consistently been subject to criticism, significantly impeding its practical application. To address this challenge, an innovative approach called lead-rivet was proposed for the in-situ growth of perovskite crystalline structures. Through the formation of S-Pb bonds, each Pb 2+ ion was firmly immobilized on the surface of the silica matrix, enabling in situ growth of perovskite nanocrystals via ion coordination between Cs + and halide species. The robust S-Pb bonding effectively restricted the mobility of lead ions and stabilized the perovskite structure without relying on surface ligands, thereby not only preventing toxicity leakage but also providing a favorable interface for depositing protective shells. The obtained perovskites exhibit intense and narrow-band fluorescence with full-width at half-maximum less than 23 nm and show excellent stability to high temperature (above 202 °C) and high humidity (water immersion over 27 days), thus making it possible to be used in varies textile technologies including melt spinning and wet spinning. The lead leakage rate of particles is only 4.15 % demonstrating excellent toxicity inhibition performance. The prepared fibers maintained good extensibility and flexibility which could be used for 3D-printing and textiles weaving. Most importantly, the detected Pb 2+ leaching was negligible as low as to 0.732 ppb which meet the standard of World Health Organization (WHO) for drinking water (<10 ppb), and the cell survival rate remained 99.196 % for PLA fluorescent filament after 24 h cultivation which showing excellent safety to human body and environment. This study establishes a controllable and highly adaptable synthesis method, thereby providing a promising avenue for the safe utilization of perovskite materials.
