文摘The recovery of precious metals(PMs)from secondary resources is critical for addressing global supply-chain vulnerabilities and sustainable resource utilization.This review systematically examines the transformative potential of metal-organic frameworks(MOFs)as next-generation adsorbents for PM recovery,focusing on their synthesis,functionalization,and multiscale adsorption mechanisms.We critically analyze conventional pyrometallurgical and hydrometallurgical methods and highlight their limitations in terms of selectivity,energy consumption,and secondary pollution.In contrast,MOFs offer tunable porosity,abundant active sites,and tunable surface chemistry,enabling efficient PM capture via synergistic physical and chemical adsorption.Advanced modification techniques,including direct synthesis and post-synthetic modification,are reviewed to propose strategies for enhancing the adsorption kinetics and selectivity for Au,Ag,Pt,and Pd.Key structure-property relationships are established through multiscale characterization and thermodynamic models,revealing the critical roles of hierarchical porosity,soft donor atoms,and framework stability.Industrial challenges,such as aqueous stability and scalability,are addressed via Zr-O bond strengthening,hydrophobic functionalization,and support immobilization.This study consolidates the experimental and theoretical advances in MOF-based PM recovery and provides a roadmap for translating laboratory innovations into practical applications within the circular-economy framework.
文摘This study aims to explore the impact of combined health education and dietary guidance on the speed of postoperative recovery in patients with gastrointestinal polyps.A specific number of patients who underwent gastrointestinal polyp resection were selected and randomly divided into a control group and an experimental group.The control group received routine nursing,while the experimental group implemented combined health education and dietary guidance on this basis.By comparing the recovery indicators of the two groups,it was found that the recovery speed of the experimental group was significantly faster than that of the control group,indicating that this combined intervention method can effectively promote patient recovery.

文摘Selective extraction of precious metals from urban mines plays a crucial role in mitigating the risk of depletion of precious metal resources and reducing waste pollution.However,a major obstacle in precious metal extraction lies in the difficulty of distinguishing the subtle differences in the physicochemical characteristics between them,especially gold and palladium.Herein,a proton-driven separation system was presented for cascade recovery of gold and palladium from waste-printed circuit boards(W-PCBs)leachate using poly(amidoxime)(PAO)hydrogel.This exhibits an ultra-high capacity,extra-fast rate,and excellent selectivity for the extraction of Au(Ⅲ)and Pd(Ⅱ).Notably,the separation of Au(Ⅲ)and Pd(Ⅱ)can be achieved with high selectivity at pH=0,resulting in a remarkable separation factor of k_(Au(Ⅲ)/Pd(Ⅱ))=36.5.This was demonstrated to originate from the differential mechanism of PAO hydrogel for the capture of Au(Ⅲ)and Pd(Ⅱ)under proton-mediated conditions.Drawing inspiration from the mechanism,the proton-driven cascade recovery system demonstrates remarkable efficiency in sequentially recovering 99.92%of gold and 99.05%of palladium from W-PCBs acid leachate.This research opens up a strategy to precisely separate and recover precious metals from e-waste of urban mines.
文摘This study addresses the challenge of predicting zinc(Zn)recovery from carbonate ores via sodium hydroxide(NaOH)leaching.This complex process influenced by variable ore composition,surface passivation effects,and nonlinear reaction dynamics,which complicate reagent optimization and process control in hydrometallurgical operations.To tackle this,a dataset containing 422 experimental observations was compiled from previous studies,incorporating ore composition and process parameters,such as NaOH concentration,leaching time,temperature,and solid-to-liquid ratio.Four regression models(decision tree,neural network,generalized additive model,and random forest)were trained and evaluated using performance metrics,such as coefficient of determination(R^(2)),root mean squared error(RMSE),mean absolute error(MAE),mean absolute percentage error(MAPE),and symmetrical mean absolute percentage error(SMAPE).Among these,the random forest model achieved the best predictive accuracy,with R^(2)value of 0.8541 on the test set and the lowest error rates,demonstrating its effectiveness in capturing the complex relationships between input variables and Zn recovery.Explainable artificial intelligence,particularly SHapley additive exPlanations(SHAP)analysis,revealed that NaOH concentration,leaching time,and solid-to-liquid ratio had the most positive influence on Zn recovery,whereas elements such as Ca,Fe,and Pb had inhibitory effects.These findings align with known geochemical behavior and provide valuable insights for reagent optimization and process effi-ciency in leaching processes.This study demonstrates the practical potential of machine learning in mineral processing,offering a scalable framework for optimizing Zn recovery from non-sulfide ores and a data-driven approach to enhance decision-making in hydrometallurgical applications.
文摘The proliferation of carrier aircraft and the integration of unmanned aerial vehicles(UAVs)on aircraft carriers present new challenges to the automation of launch and recovery operations.This paper investigates a collaborative scheduling problem inherent to the operational processes of carrier aircraft,where launch and recovery tasks are conducted concurrently on the flight deck.The objective is to minimize the cumulative weighted waiting time in the air for recovering aircraft and the cumulative weighted delay time for launching aircraft.To tackle this challenge,a multiple population self-adaptive differential evolution(MPSADE)algorithm is proposed.This method features a self-adaptive parameter updating mechanism that is contingent upon population diversity,an asynchronous updating scheme,an individual migration operator,and a global crossover mechanism.Additionally,comprehensive experiments are conducted to validate the effectiveness of the proposed model and algorithm.Ultimately,a comparative analysis with existing operation modes confirms the enhanced efficiency of the collaborative operation mode.

文摘Thermomagnetic generation(TMG),a heat-to-electricity conversion technology based on the thermomagnetic effect,offers high reliability and broad adaptability to diverse heat sources.By exploiting the temperature-dependent magnetization of thermomagnetic materials,TMG converts thermal energy into electrical energy through cyclic changes in magnetic flux based on Faraday's law.The performance of TMG systems is largely governed by the intrinsic properties of the working materials and the design of device architecture.Ideal TMG materials exhibit sharp and reversible magnetization transitions near the operating temperature,low thermal hysteresis,and high thermal conductivity.Device configurations can be broadly categorized into active and passive systems:active TMG devices rely on controlled thermal cycling and optimized magnetic circuits for enhanced output,whereas passive devices utilize self-actuated mechanical motion to generate electricity.In this topical review,we provide a comprehensive overview of recent advances in TMG materials and device configurations.Furthermore,we discuss future development trends and offer perspectives on experimental strategies to advance this field.
文摘This study investigated the effects of xu-argument-based continuation writing on learners’processing of source texts.Seventy-five participants were randomly assigned to three conditions:(1)continuation writing,(2)summary writing,or(3)reading comprehension.Eye-tracking data were collected during reading,measuring early(first fixation duration,first pass duration)and late(go-past time,total fixation duration)eye movements.During writing,source-text rereading was tracked via fixation counts and durations.Results showed that task type did not affect initial lexical access,as first fixation duration showed no group differences.However,both production groups exhibited significantly longer first pass durations than the reading comprehension group.Late measures revealed a gradient pattern:the continuation writing group spent significantly longer gopast time and total fixation duration than the summary writing group,which exceeded the reading comprehension group.This indicates that continuation tasks promoted deeper cognitive engagement during reading.During writing,the continuation writing group spent more time rereading the source text with higher fixation counts than the summary writing group.These findings suggest that continuation writing triggers more intensive reader-text interaction during pre-writing and enhances comprehension-production coupling through sustained attention to input during writing.This study sheds light on the cognitive mechanisms underlying the theoretical and pedagogical value of xu-argument.
文摘This editorial examines the emerging potential of traditional Chinese medicine(TCM)in enhancing postoperative recovery following gastroenteroscopy,highlighted by a 2025 randomized controlled trial by Hong et al.The study,involving 120 patients,demonstrates that meridian flow injection(MFI)combined with transcutaneous electrical acupoint stimulation(TEAS)significantly improves gastrointestinal(GI)function,evidenced by a reduced time to first defecation(3.20±1.04 days vs 3.98±1.27 days,P<0.001),lowers stress biomarkers(e.g.,reduced cortisol and norepinephrine),and enhances clinical efficacy(93.33%vs 75.00%,P=0.006).Leveraging TCM’s five-element theory and Ziwu Liuzhu timing,the intervention targets key acupoints such as Zusanli(ST36)with a herbal paste comprising Qingpi,Houpu,and rhubarb,delivered transdermally to optimize bioavailability.This approach harmonizes ancient TCM principles with contemporary evidence-based practice,offering a holistic strategy to address postoperative nausea,delayed motility,and patient discomfort.Currently,integrative methods like MFI-TEAS are gaining traction,supported by recent meta-analyses that affirm TEAS’s efficacy in accelerating GI recovery across surgical contexts,including shortened times to first exhaust and defecation.This reflects a growing recognition of TCM’s role in perioperative care amidst rising global endoscopy demands.Looking forward,future research should prioritize multicenter,doubleblinded trials to enhance generalizability,adhere to standardized reporting frameworks such as CONSORT and STRICTA,and employ advanced tools like multiomics and functional magnetic resonance imaging to elucidate mechanistic pathways,including gut-brain axis modulation and microbiota-immune interactions.Such developments promise to refine these interventions,fostering a seamless integration of TCM with Western medicine and delivering tailored,patientcentered solutions to improve postoperative outcomes worldwide.

文摘Ceramic 4D printing,which integrates dynamic deformation with additive manufacturing,demonstrates significant potential in intelligent manufacturing,on-demand shaping of complex structures,and multifunctional device development.Its core advantage lies in endowing materials with environmentally responsive dynamic deformation capabilities.However,current technologies still face limitations in responsiveness,reversibility,and mechanical performance.To address these challenges,this study proposes a programmable ceramic precursor system based on synergistic reinforcement of phase-separating hydrogels and shape memory polymers,combined with a nano-ceramic particle enhancement strategy.Using stereolithography 3D printing,high-precision fabrication of complex structures was achieved.By adjusting precursor composition,programming time,and structural thickness,the phase-separation kinetics-driven delayed recovery mechanism was elucidated,enabling precise control over recovery onset time.Furthermore,the thermal response mechanism of the precursor materials is explored,along with their potential for multi-shape transformation in biomedical applications,which is further extended to shape memory polymer systems.By employing a layered printing strategy,the autonomous reversible deformation of ceramic precursors is realized,providing new possibilities for specific applications.

文摘Urine consists of approximately 95%water,3.5%organic matter,and 1.5%inorganic salts.Membrane distillation(MD)offers a potential approach for urine resource utilization.To some extent,it reduces the loss of nitrogen and phosphorus resources.However,MD is also accompanied by problems such as high membrane cost,membrane fouling and membrane wetting.In light of these issues,this study employs polytetrafluoroethylene(PTFE)as the separation layer and polypropylene(PP)as the support layer to make a distillation membrane.The feasibility and efficiency of the PTFE-PP membrane in intercepting and recovering nitrogen and phosphorus from source-separated urine were investigated.Results obtained through 14 days of continuous operation demonstrated that the recovery rates of nitrogen and phosphorus were 95%and 99%,respectively.The dissolved organic carbon recovery rate was 95%,and urea as well as the macromolecular organic matter in dissolved organic matter were significantly intercepted.The phosphorus content in the permeate was 0.022 mg/L,which met theⅡclass standard of China’s surface water and the basic water use standard of the United States Environmental Protection Agency.This finding reduces the pressure on sewage treatment plants.PTFE-PP distillation membrane has important potential in recovering nitrogen and phosphorus from urine and alleviating global water shortage.

文摘In April 2016,a moment magnitude(Mw)7.8 earthquake struck near Muisne(Pedernales),Ecuador,causing 671 fatalities,displacing>30,000 people,and generating approximately USD 3.6 billion in economic losses that severely impacted the coastal province of Manabí.Nine years later,the recovery trajectory of its principal urban centers-Pedernales,Manta,Portoviejo,and Chone-offers a critical perspective to assess adaptive resilience in earthquake-prone coastal cities of Latin America.This study conducts a regional assessment of post-earthquake recovery using the 4Rs resilience framework-robustness,redundancy,resourcefulness,and rapidity-applied across housing,health,education,infrastructure,and economic sectors.Official reports,statistical databases,and field validations collected between 2016 and 2025 provide the basis for documenting both progress and persistent challenges.The findings indicate that robustness improved with the enforcement of the Ecuadorian seismic code NEC-15 and the adoption of advanced technologies such as base isolation and supplemental damping in hospitals and high-rise buildings.Redundancy expanded selectively,being stronger in healthcare yet limited in housing and utilities.Resourcefulness varied across cities:municipal leadership and civic oversight in Manta and Portoviejo facilitated adaptive recovery,whereas Pedernales and Chone remained dependent on central agencies.Rapidity was similarly uneven;lifeline services were restored promptly,but complex projects-including hospitals,sewer systems,and residential complexes-faced delays of five to nine years.Structural assessments of 97 buildings revealed that nearly half remain without reinforcement,with recurrent deficiencies such as soft-story mecha-nisms,brittle masonry infill,and reinforcement corrosion sustaining latent seismic risk.Governance fragmen-tation,equity gaps,and insufficient monitoring thus emerged as critical barriers,underscoring the need for integrated governance,community participation,and AI-enabled monitoring to strengthen long-term disaster recovery in coastal cities.
