The presence of organic dyes in the aquatic environment poses a significant threat to ecosystems and human health, thereby necessitating the development of effective and green adsorbents for their removal. To address this concern, modified corn straw cellulose was prepared from corn straw and betaine hydrochloride by a dry method. The adsorbent’s structure was characterized by FTIR, SEM, XRD, zeta potential, and TG-DTG. The adsorption capacity for Acid Red 1 (AR1) was evaluated, and the effects of initial pH, adsorbent dosage, initial dye concentration, and NaCl concentration on the adsorption capacity were investigated. The adsorption of the anionic dye AR1 onto the adsorbent followed the pseudo-second-order kinetic model and the Langmuir isotherm, with a maximum monolayer adsorption capacity of 315.2 mg/g at 298 K. The adsorption process was predominantly governed by electrostatic interactions between the adsorbent surface and the dye molecules. This study provides a viable strategy for the dry preparation of adsorbent from waste biomass for anionic dye adsorption.

Volatile flavor compounds are key determinants of the sensory quality and consumer preference of olive oil, and their compositional profiles are significantly influenced by geographical origin. To elucidate the regional differences in volatile flavors, this study employed headspace-gas chromatography-ion mobility spectrometry (HS-GC-IMS) combined with chemometrics to analyze oil samples from three major Chinese producing regions—Gansu, Yunnan, and Sichuan—as well as representative imported origins. A total of 56 volatile compounds were identified, including aldehydes, esters, alcohols, ketones, and terpenes. Fingerprint analysis revealed that terpenes were present at specifically high levels in some samples from Gansu, whereas alcohols and esters were more abundant in specific Sichuan samples and among the imported oils. Principal component analysis (PCA) showed limited overall separation among the regions, whereas partial least squares-discriminant analysis (PLS-DA) effectively discriminated samples from different geographical origins and identified 15 potential marker compounds with variable importance in projection (VIP) scores > 1. This study demonstrates that HS-GC-IMS coupled with chemometrics is an effective approach for screening volatile markers indicative of geographical origin, providing a potential research direction and data support for the traceability of olive oil.

This work presents a high-sensitivity surface plasmon resonance (SPR) temperature sensor based on a BK7 prism coated with silver film and NiO nanoflowers. NiO nanoflowers were synthesized via hydrothermal method and deposited onto the Ag film using a drop-casting technique (3 cycles optimized). The resulting BK7/Ag/NiO nanoflowers structure significantly enhances refractive index (RI) sensitivity. Finite element method (FEM) simulations and experimental measurements confirmed the sensor's performance. The Ag/NiO nanoflowers sensor achieved a remarkable RI sensitivity of 4138.34 nm/RIU, representing a 63.83% improvement over a bare Ag film sensor. Leveraging this enhanced sensitivity and the strong thermo-optic coefficient of silicone oil, a temperature sensor (BK7/Ag/NiO nanoflowers /silicone oil) was developed. It exhibited an excellent temperature sensitivity of -1.61 nm/°C over the range of 25 °C to 75 °C, with a low detection limit of 0.075 °C. The sensor also demonstrated good repeatability and stability, making it a promising candidate for highly sensitive temperature sensing applications.

For the technical challenges in the smelting process of bismuth sulfide concentrate and hazardous characteristics of lead dust, a clean co-smelting process of bismuth sulfide concentrate and lead dust is introduced in this paper. The hazardous waste lead dust (ZnO) is used as a sulfur-fixing agent to recover metallic bismuth and lead from furnace charge by reductive sulfur-fixing smelting. This process fixes elemental sulfur into iron matte, avoiding the emission of sulfur-containing gases. The mechanism of bismuth extraction and sulfur fixation in co-smelting was revealed by thermodynamic calculations and phase transformation experiments. Under the reducing atmosphere, PbSO 4 in lead dust was firstly reduced to PbS, then Bi 2 S 3 and PbS interacted with ZnO to form Bi 2 O 3 , PbO, and ZnS, and finally intermediate products, Bi 2 O 3 and PbO, were reduced to metallic bismuth and lead. The feasibility and reliability of this technique were confirmed by process simulation experiments. Under the optimum conditions (W Bismuthine :W Lead dust :W Na2CO3 :W Coke = 10:6:15:1, 900 °C, 60 min), the bismuth recovery rate and sulfur-fixing rate were 98.57% and 97.32%, respectively, and the grade of crude bismuth was 89.81%. This technique provided a new solution for bismuth extraction and lead-bearing solid waste environmentally-friendly disposal.

Multifaceted bio-contamination, including natural organic matter (NOM) and microbial colonization, challenges the application of hydrophobic polyvinylidene fluoride (PVDF) membranes in water purification. To address organic and biofouling, a UV irradiation grafting strategy is developed to fabricate dual-functional PVDF membranes with integrated antibacterial and anti-fouling capabilities. Two quaternary ammonium salts (QAS)—short-chain allyltrimethylammonium chloride (ATMAC, C6) and long-chain methacryloxyethyltrimethylammonium chloride (DMC, C9)—are grafted onto PVDF membranes. Herein, C6 and C9 denote quaternary ammonium salts bearing hexyl and nonyl alkyl substituents, respectively. The best surface modification induced a 43.4% reduction in water contact angle (88.5° to 45.1°), demonstrating significantly enhanced hydrophilic characteristics of the modified membranes, surfaces with enhanced positive character (zeta potential shifted from − 30.22 mV to − 20.15 mV), and dual antifouling mechanisms via pore-clogging mitigation and hydration layer formation. The PVDF membrane grafted with 7.5 wt% DMC demonstrates optimal performance, achieving a 98.5% flux recovery ratio during sodium alginate filtration and > 99% bactericidal efficiency against E. coli and S. aureus . By grafting QAS(e.g., DMC/ATMAC) onto PVDF membranes, this approach mitigates irreversible fouling while sustaining long-term antimicrobial activity, providing a robust solution for biofouling-resistant membranes in sustainable water treatment.

Solar-driven atmospheric water harvesting (SAWH) holds significant promise for decentralized water supply. However, its widespread application is hindered by two critical limitations: underutilization of high-humidity adsorption windows during nighttime and insufficient desorption during daytime due to the high desorption temperature requirement of conventional sorbents. To overcome these challenges, this study proposes a composite sorbent strategy by synergistically combining the low enthalpy of vaporization of LiCl with the robust adsorption capacity and stability of a metal‒organic framework (MOF, specifically Ni 2 Cl 2 (BTDD), H 2 BTDD = bis(1 H −1,2,3-triazolo[4,5- b ],[4′,5′- i ])dibenzo[1,4]dioxin). This design leverages the complementary properties to achieve lower desorption temperatures ( e.g ., < 60 o C in device level) compared to typical MOF-based systems (usually >90 o C in device level), thereby significantly reducing the energy consumption for desorption. Concurrently, the composite exhibits extended adsorption duration within the high-humidity window. Field validation across diverse climatic regions demonstrates the composite’s exceptional wide-range environmental stability and performance. The resulting SAWH device achieves a solar-to-water generation improvement up to 91% in a continental field test. This work presents a generalizable and effective pathway for enhancing SAWH performance through synergistic material engineering, enabling efficient water production and thermal control under varying environmental conditions.

The increasing global electricity demand underscores the urgent need for clean energy solutions. Thermoelectric materials, capable of converting waste heat into electricity, present a promising avenue. However, their efficiency is often compromised by intermittent heat sources. To address this, we propose a radial thermo-actuated thermoelectric/phase-change system inspired by the energy-conserving mechanism of the sun starfish’s wrist foot. This design employs shape memory alloy to optimize heat source utilization. The device autonomously opens to sustain a temperature gradient during sufficient heat supply and closes to minimize heat dissipation when the source is inadequate. Notably, the closed-state delays the hot-end temperature drop by ~ 1700 s, significantly reducing energy loss. Further integration with a photothermal-enhanced phase change material yields an all-day self-powered thermoelectric system. Daytime operation achieves a maximum temperature difference of 28.64 °C and an output voltage of 14.89 mV, while nighttime performance maintains an average temperature difference of 6.21 °C, ensuring stable heat supply. Our work introduces a scalable strategy for sustainable power generation in outdoor environments.

For industrial water electrolysis, the development of active and stable catalysts for the oxygen evolution reaction remains a challenge. Here, we report a heterostructure catalyst composed of NiFe layered double hydroxide nanosheets anchored on pyramidal Fe 2 (MoO 4 ) 3 to activate lattice oxygen for efficient and durable oxygen evolution. Our investigation reveals that oxygen vacancies within the NiFe layered double hydroxide and the internal electrical field at the material interface optimize the electronic states, allowing oxygen atoms within the crystal lattice to participate directly in the reaction. The resulting heterostructured NiFe LDH/FeMoO catalysts possess high oxygen evolution reaction activity in 1 M KOH electrolyte with a low overpotential of 316 mV at 2 A cm −2 and maintain long-term stability over 3,000 h. Furthermore, integrating this anode into a solar-powered electrolyzer yields a high solar-to-hydrogen efficiency of 20.15%. This work provides a promising strategy for designing stable catalysts and advancing the integration of renewable energy with water electrolysis to produce clean hydrogen at scale.

Background: One promising strategy to generate humanized organs is through embryo complementation by injecting human pluripotent stem cells (PSCs) into gene-edited porcine embryos. This strategy is predicated on how human cells adapt to a porcine environment, which has a body temperature of 38.5 °C, much higher than that of the human body. Results: Here, we present an in vitro model to address this problem by coculturing human and porcine induced PSCs at 38.5 °C and inducing them to generate cardiomyocytes. We show that co-cultured human cells can differentiate into myocardial features with the help of porcine cells at an enhanced differentiation rate. Mechanistically, we show that co-cultured human cells respond to elevated temperature by activating a stress response with the PI3K-Akt-mTOR signaling pathway activated. Moreover, a model mimicking embryo complementation by knocking out MYH6 in pig PSCs reveals the potential risk of porcine cells leaking into human-derived tissues. Conclusions: Together, our studies present a novel model system to evaluate human and porcine cell co-differentiation that may guide the planning of in vivo experiments.

Although poly(urethane-urea) elastomers (PUEs) possess excellent mechanical properties and durability, their inherent flammability and inability to self-repair after damage significantly limits their applications in high-end fields. To address this challenge, this study employs a supramolecular chemistry approach by simultaneously incorporating multiple hydrogen bonds as dynamic cross-linking points and a phosphorus-nitrogen synergistic flame-retardant structure into the poly(urethane-urea) network. The multiple hydrogen bonds endow the material with efficient intrinsic self-healing capability, while the phosphorus-nitrogen flame retardant ensures outstanding thermal stability and flame resistance, leading to the successful synthesis of a high-performance multifunctional poly(urethane-urea) elastomer. Experimental results demonstrated that when the content of the flame retardant diethyl (2-((2-aminoethyl)amino)ethyl)phosphoramidate (DEPTA) was 10 wt%, the resulting PUE/10%DEPTA achieved a V-0 rating in the vertical burning test, with a limiting oxygen index (LOI) of 30%. Concurrently, the elastomer maintained good toughness, exhibiting a tensile strength of 27.3 MPa, an elongation at break of 601%, and a self-healing efficiency of up to 94.46%. This breakthrough shows significant promise for advanced engineering applications that demand fire safety, structural durability, and extended service life through self-repair.

The convenient and widespread implementation of doxycycline (DOXY) detection still requires the development of new methods to enable rapid detection across various environments. In this study, blue-emitting nitrogen-doped carbon dots (N-CDs) were successfully prepared using glutamine and anhydrous citric acid as primary materials. Correspondingly, a simple and sensitive fluorescence method for detecting DOXY was developed using N-CDs as probe. The fluorescence intensities of N-CDs were significantly quenched by variable concentrations of DOXY based on the internal filtration effect, which was verified through quantum efficiency correction experiment. Under the optimized testing conditions, the concentrations of DOXY showed a good linear relationship with fluorescence quenching efficiencies in the range of 0.1-35 μg/mL, with a detection limit (LOD) of 0.018 μg/mL, suggesting the good analytical performance. This method was successfully applied for the determination of DOXY in human plasma, dairy products and tap water samples, demonstrating satisfactory recoveries and reproducibility. The results highlight the promising potential of this approach for clinical monitoring of blood drug concentrations, detection of drug residues, and environmental sample analysis.

Polycaprolactone (PCL)-shape memory polyurethane (SMPU) is widely used in various fields due to its excellent performance. However, PCL-SMPU often struggles to obtain high fracture elongation and shape memory recovery ability because of its large crystal size and relatively low hydrogen bonding energy. To overcome the difficulties and achieve better properties, our research proposed an optimization strategy that combines hydrogen bonding and crystallization control, which involves introducing a small amount of polyethylene adipate 1, 4-butanediol ester (PBA) and adjusting the ratio of soft-to-hard segments. The addition of PBA can form strong hydrogen bonding with isocyanate and form secondary hydrogen bonding with PCL, which can significantly improve the tensile strength and fracture elongation through multiple-level hydrogen bonding. Moreover, regular PBA chains can form microcrystals, thereby not only ensuring the crystallinity but also refining the large crystal size of PCL segments and optimizing the stress distribution. Apart from compounding PBA, the adjustment of the ratio of soft-to-hard segments plays a significant role in resulting in a better overall performance. This modification endows the material with excellent mechanical properties (tensile strength of 20.29 MPa, elongation at break of 1462.09%) and shape memory properties. (Both shape recovery rate and shape fixation rate are above 99%, and the shape recovery driving force is 4.11 MPa.) Besides, the synthesized SMPU can achieve reversible deformation of 16.85% under 0.2 MPa external force. Based on the excellent performance mentioned above, this material has great potential for application in the field of intelligent actuators. Graphical
The synthesized PBA/PCL-based shape memory polyurethane acquires great overall performance, making it potential in the field of intelligent actuator fields and so on.
