Incorporating perovskite nanocrystals(PNCs)in the glass matrix has been demonstrated to be an effective route to improve their stability for long-term operation.However,simultaneously achieving high luminance and high photoluminescence(PL)quantum yield(QY)is challenging.Herein,we report a strategy that employs fluoride ion doping to modify the three-dimensional glass network,thereby optimizing the crystallization behavior of PNCs and achieving both high luminance and high PLQY in full-spectrum.Leveraging these high-performance transparent composites,we constructed a dynamic holographic multicolor display system by integrating with a spatial light modulator(SLM),achieving a pixel density as high as 20,247 pixels per inch(PPI).We further propose a vertically stacked,multilayer full-color display architecture that overcomes the limitations of color filters in light-utilization efficiency and the bottlenecks of conventional planar sub-pixel layouts in terms of spatial utilization and resolution. 展开更多

Amine-based absorption has been regarded as the benchmark technology for CO2capture because of its high processing capacity and relatively mature process.However,its high-energy consumption associated with solvent regeneration severely limits large-scale deployment.In recent years,catalytic regeneration has emerged as a promising process intensification strategy to reduce regeneration energy consumption.By employing catalysts,the energy barriers for carbamate and bicarbonate decomposition can be largely reduced through enhanced proton transfer,acid-base cooperativity,and interfacial mass transport.This review provides a critical overview of recent advances in the catalytic regeneration of CO2-rich amine solutions.Acid catalysts are first classified according to material types and structural features.The catalytic mechanisms proposed for different systems are then discussed,together with catalyst deactivation and stability issues.Furthermore,emerging data-driven catalyst design strategies based on machine learning,as well as process-level evaluations using Aspen simulations,are summarized.Finally,recent pilot-scale demonstrations and the integration of catalytic regeneration with other process intensification technologies are reviewed.Key challenges and future research prospects are identified,including catalyst durability under alkaline conditions,solvent-catalyst compatibility,quantitative identification of active sites in liquid environments,and full-process energy optimization.This review aims to provide insight into the rational development of catalytic regeneration of amine solution for energy-efficient CO2capture technologies. 展开更多

The use of Al-V alloys as intermediate additives is pivotal for producing high-performance Ti alloys.Traditionally,the synthesis of these alloys relies on high-purity V2O5,with sodium metavanadate as an essential intermediate in V2O5production.This study explores an alternative approach utilizing sodium metavanadate directly,offering an aluminothermic process to alleviate the environmental impact and reduce the time required for V2O5preparation.Al-V alloys are synthesized using sodium metavanadate derived from a shale V-rich solution,and the impurity-migration behaviors are comprehensively analyzed,specifically focusing on Fe,Al,and Na.The result sreveal that Al interacts with CaO to form a slag phase that is different from the alloy,whereas Na undergoes a sequence of reductions (NaVO3→Na2V2O5→NaVO2→Na)and volatilizes at 25-1200℃,thereby avoiding incorporation into the alloy.Fe,reduced by Al,enriches the alloy phase and induces a phase transition(Al-V→Al-Fe→Fe-V)in the presence of excess Fe.Sodium metavanadate(Fe≤0.05wt%)derived from the shale V-rich solution enables the production of a uniform AlV65 alloy with 66.56wt%V,33.14wt%Al,0.08wt%Fe,0.07wt%C,0.02wt%N,and 0.12wt%O.These results establish a streamlined,efficient framework for the future preparation of Al-V alloys from shale V-rich solutions. 展开更多

In this paper,a generalized(3+1)-dimension variable-coefficient nonlinear evolution equation is investigated,which serves as a model for describing nonlinear wave behaviors in shallow water,ion-acoustic wave fluid mechanics and plasma physics.The Painlevéintegrability is tested by the Weiss,Tabor and Carnevale(WTC)method with the simplified form of Krustal.The bilinear form of the equation is derived through the application of the Hirota bilinear method.Building on the bilinear equation,a broad range of analytical solutions are then obtained,including X-shaped and Y-shaped soli ton solutions,lump solution,breather solution,and interaction solutions.In addition,another type of soliton solution,periodic solution,and ratio of trigonometric functions are derived. 展开更多

In this study,high-performance D18:L8-BO bulk heterojunction organic solar cells(OSCs)were prepared by employing a hot-solution strategy to optimize the active layer morphology during the film solidification process.By heating the chloroform(CF)solution to 70℃(slightly above the boiling point of CF,~61.2℃),an optimal balance between solvent evaporation and molecular self-assembly was achieved,resulting in enhanced crystallinity,favorable π-π stacking,and ideal nanoscale phase separation.These improvements significantly boost the power conversion efficiency from 17.74%(for the device processed at a room temperature of 30℃)to 19.56%.Moreover,the in-situ grazing-incidence wide-angle X-ray scattering technology was utilized to monitor the crystallization and morphology evolution of the active layer,offering real-time insights into molecule self-assembly and phase separation dynamics during active layer solidification.This work not only provides a simple and scalable approach for fabricating high-efficiency OSCs but also offers fundamental insights into the influence of solution temperature on active layer morphology evolution dynamics,paving the way for large-scale industrial production of organic solar cells. 展开更多

Let A be a 3×3 singular or diagonalizable matrix,all solutions to the Yang-Baxter-like matrix equation have been determined.However,finding all solutions for full rank,non-diagonalizable matrices remains challenging.By utilizing classification techniques,we establish all solutions of the Yang-Baxter-like matrix equation in this paper when the coefficient matrix A is similar to non-diagonalizable matrix diag(λ,J2(λ))withλ̸=0.More specifically,we divide the non-diagonal elements of the solution into 10 different cases.By discussing each situation,we establish all solutions of the Yang-Baxter-like matrix equation.The results of this work enrich the existing ones. 展开更多

Semitransparent organic photovoltaics(ST-OPVs)for building integration represent a pivotal direction in the development of photovoltaic industry.Solution-processed silver nanowires(AgNWs)are considered promising candidates for transparent electrodes in semitransparent devices due to their high transparency-conductivity-efficiency merit,large-scale processability,and low cost.In this work,we develop two solution-processed organic–inorganic hybrid electrodes,named AgNWs-PD and AgNWsPC,utilizing AgNWs as the conductive framework and aliphatic amine-functionalized perylene-diimide(PDINN)as the sandwiched material,while AgNWs-PC exhibits significantly improved electrical conductivity and enhanced contact area with the underlying electron transport layer.The optimized device achieves a power conversion efficiency of 9.45%with an open circuit voltage of 0.846 V,a high filling factor of 75.4%,and an average visible transmittance(AVT)of 44.0%,delivering an outstanding light utilization efficiency(LUE)of 4.16%,which is the highest reported value for all solution-processed ST-OPVs.In addition,by coupling a 30-nm tellurium dioxide atop AgNWs-PC,the bifaciality factor of derivative devices improves from 73.7%to 99.4%,while maintaining a high bifacial LUE over 3.7%.Our results emphasize the superiority and effectiveness of PDINN-sandwiched AgNWs electrodes for highperformance and all solution-processed ST-OPVs. 展开更多

Farmers in China often use nitrogen(N)fertilizers to ensure adequate crop growth.However,inappropriate applications have increased the risk of environmental pollution,lowered maize yields,and reduced profits for farmers.Proper N fertilizer management is crucial for improving yield and nitrogen use efficiency(NUE).This study conducted a three-year experiment involving nine N treatments(0,45,90,135,180,225,270,315,and 360 kg ha-1)on a field under nitrogen fertilizer precision management(NFPM)in Northeast China.The results were compared with studies published within the past decade that analyzed yield and dry matter(DM)content under two management practices in Northeast China:conventional nitrogen fertilization management(CNFM)and water-saving fertilization management(WSFM).The findings reveal that maize yield increases with rising N application rates up to 270 kg ha-1,after which yield decreases.The kernel number(KN)and kernel weight(KW)of maize grown under NFPM were 13.7 and 14.7%higher than those grown under WSFM,respectively.Furthermore,they surpassed crops grown under CNFM by 38.4 and 21.2%,respectively.The maximum total yield of the NFPM treatment was 41.8 and 78.8%higher than under WSFM and CNFM,respectively.In addition,compared with CNFM and WSFM,NFPM significantly increased NUE across the various N-level treatments.Optimizing nitrogen management can help farmers to achieve higher yields and promote sustainable agricultural development. 展开更多

Towards the development of highly efficient electrochromic coatings,the crystallinity,morphology(e.g.size and shape)of electrochromic nanomaterials,and their charge insertion capacities play a significant role.Herein,we report the structure-dependent colouration effciency in electrochromic coatings based on the use of 0D,1D and 2D tungsten trioxide(WO3)nanostructures.A series of WO3with different nanostructures were prepared and used as working electrodes to fabricate electrochromic devices for smart windows applications.Facile spray coating was applied on fluorine-doped tin oxide(FTO)substrate to make~70%transparent working electrodes to investigate their charge insertion capacities,electrochromic active surface area,and colouration efficiency.Results showed that the 2D WO3nanoflakes displayed the highest diffusion coefficient for the intercalation of 1.52×10-10cm2/s with an increased electrochemical active surface area of 25.10 mF/cm2,a large modulation of optical reflectance(42.63%)with 3.79 s shorter response time for bleaching and a greater colouration efficiency(CE)value(89.29 cm2/C)at 700 nm compared to the CE value for 1D WO3(of 22 cm2/C)and 0D WO3(8 cm2/C).The outcome of this study provides a new insight and valuable contribution to design an efficient electrochromic coating by controlling and optimising the nanostructures of selective electrochromic materials. 展开更多

Single-time fertilization(STF)with controlled release blended fertilizer(CRBF)improves grain yield and nitrogen use efficiency(NUE)in rice production.However,the impact of soil nitrogen(N)distribution and root growth on rice yield and NUE under STF with CRBF remains unclear.Here,a two-year field experiment investigated the effects of two fertilizer types(normal urea(U)and CRBF)and two single-time fertilization methods(broadcast and side-deep fertilization)on the soil N distribution,plant N uptake,root characteristics,grain yield,and NUE.The results showed that CRBF under STF increased the averages of plant dry matter accumulation,N uptake,grain yield,nitrogen recovery efficiency(NRE),and nitrogen agronomic efficiency(NAE)by 8.29,21.85,10.57,79.28,and 74.8%compared to the other treatments,respectively.Side-deep fertilization with CRBF further increased NUE by 12.78%compared to broadcast.Moreover,CRBF under STF increased the leaf SPAD value and glutamine synthetase(GS)/glutamine oxoglutarate aminotransferase(GOGAT)activity by 5.93 and 25.58%,respectively.CRBF under STF increased the soil inorganic N concentration and showed a“rising early and stabilizing later”pattern.In addition,CRBF under STF improved rice root growth and increased the averages of root biomass,total root number,root average diameter,total root length,total root surface area,and total root volume by 28.30,28.56,18.64,13.38,35.26,and 37.06%,respectively,at the tillering and heading stages.Partial least squares path modeling indicated that CRBF under STF increased the soil inorganic N concentration which improved root morphology,thereby increasing N uptake and improving the rice yield and NUE.Taken together,our findings show that CRBF with single-time fertilization is the preferred N fertilizer strategy for achieving high yield and efficiency in rice,and that side-deep fertilization is the optimal fertilization method. 展开更多

An aircraft carrier's formidable combat capability relies on sorties,with efficient deck operations as the core to enhance sortie and recovery capabilities.First,this study develops an integrated mathematical model for carrier-based aircraft deployment,sortie,and maintenance scheduling to assist decision-makers in formulating sorties and coordinating resource allocation(e.g.,personnel,equipment),aiming to optimize the comprehensive effectiveness index of integrated carrier-based aircraft scheduling.Second,a hybrid multi-layer coded genetic algorithm(HMCGA)integrated with heuristic rules is proposed;it uses four-layer coding to resolve inter-sub-process coupling and supports integrated carrier-based aircraft scheduling,covering hangar transfer,deck transfer,aircraft maintenance support,and sortie execution.Then,case simulation shows the proposed model and algorithm effectively improve operational effectiveness and ensure accuracy.Finally,comparisons of 50 independent simulation results(PSO,DE,WOA,CPLEX)effectively validate HMCGA's superiority and universality in solving integrated carrier-based aircraft scheduling problems across fleet scales,further confirming the model and algorithm's reliability. 展开更多

Strong seismic excitation and fault dislocation are likely to occur simultaneously in high-intensity seismic zones,causing severe damage to tunnels crossing active fault zones.This paper aims to develop a novel analytical solution to determine the longitudinal mechanical responses of tunnels subjected to the combined effects of seismic waves and strike-slip faulting.Adopting the elastic springbeam model,the seismic waves are modelled as shear horizontal(SH)waves and the fault dislocation follows an S-shaped pattern;the superposition principle for free-fielddisplacements caused by both effects is assumed.In addition,the transmission and reflectionof seismic waves at the fault-rock geological interface and the tangential contact conditions at the tunnel-rock interface are considered.The analytical model is validated against numerical simulations,confirmingits accuracy in calculating tunnel responses.Moreover,a parametric study is conducted to evaluate the impact of key factors,including fault displacement,fault zone width,fault dip angle,earthquake frequency,rock conditions,tunnel lining stiffness,and tangential contact conditions,on tunnel responses.Compared with each effect alone,the combined effects of seismic waves and strike-slip faulting significantlychange the tunnel deformation and internal forces,leading to increased tunnel responses,especially within the fault zone and near the fault-rock interfaces.Depending on specificparameters,tunnel responses can be classifiedinto seismic-dominated,faulting-dominated,and seismic-faulting coupled responses on the basis of the relative contributions of each effect.The proposed analytical solution can be applied to quickly predict the longitudinal mechanical behaviour of tunnels under such combined effects in engineering applications. 展开更多

Coordinating light and nitrogen(N)distribution within a canopy is essential for improving rice yield and resource use efficiency.However,limited research has examined light and N distribution in response to planting density and N rate,and their relationships with grain yield,radiation use efficiency(RUE),and N use efficiency for grain production(NUEg)in rice.A two-year field experiment was conducted with two hybrid varieties under three N levels,0 kg ha-1(N1),90 kg ha-1(N2)and 180 kg ha-1(N3),and two planting densities,22.2 hills m-2(D1)and 33.3 hills m-2(D2).Results showed 3.4%higher yield and 4.4%higher NUEg under N2D2 compared with N3D1.The extinction coefficient for N(KN)and light(KL)and their ratio(KN/KL)at heading stage were significantly influenced by N rate,planting density,and their interaction.KNdecreased with the increase of N input or planting density.Compared to N1,KNdecreased by 43.5 and 58.8%under N2 and N3,respectively,while KNunder D2 decreased by 16.0%compared to D1.Higher KLand KN/KLvalues occurred under low N rates,with opposite trends under high N rates.Increased planting density led to decreased KLand KN/KLvalues.N2D2 demonstrated higher KLand KN,and thus comparable KN/KL,compared to N3D1.Correlation analysis revealed KLnegatively correlated with RUE,while KNand KN/KLpositively correlated with NUEg.These findings indicate that increasing planting density under reduced N input could maintain rice yield while enhancing resource use efficiency through regulation of canopy light and N distribution. 展开更多

In the water-scarce North China Plain(NCP),choosing between straw mulching(SM)for surface conservation and straw incorporation(SI)for soil amelioration is a critical agricultural dilemma.However,their effects on soil water dynamics and crop productivity under different irrigation levels remain unclear.We conducted a two-year field experiment comparing SI and SM under three irrigation levels in winter wheat:no irrigation(I0),60 mm irrigation at jointing(I60),and 60 mm irrigation at both jointing and heading(I60+60).Soil water dynamics were monitored,field-scale evapotranspiration(ET)was estimated using a water-balance approach,and aboveground dry matter,yield components,and water use efficiency(WUE)were measured.SM maintained higher topsoil water content early in the season,whereas SI generally showed greater changes in soil water storage(ASWS)and higher mean daily ET.Despite weaker early-stage surface water conservation,SI increased aboveground dry matter and grain yield by 5.2%-5.6%,resulting in 3.4%-4.0% higher WUE,with the advantage reaching 4.8%-4.9% under I60.This advantage was associated with improved early sink establishment(higher spike numbers)and superior ET conversion efficiency,requiring 18.8% less ET per unit dry matter increment.Under160+60,the relative advantage of SI narrowed,indicating diminishing marginal yield response to additional ET.A conceptual model was developed to synthesize these straw return-irrigation interactions.We identified SI-I60+60(highest yield)and SI-I60(highest WUE)as optimal coupling modes,and recommend SI-I60 as the optimal management practice for this region,offering a practical strategy for winter wheat production under water-limited conditions. 展开更多

The Shine-Dalgarno(SD)sequence and its adjacent flanking regions,including the translation standby site(TSS)and the N-terminal coding sequence(NCS),play critical roles in regulating ribosome recruitment,translation efficiency,and mRNA stability against RNase degradation.However,structure-activity relationships governing these regions remain poorly characterized,and their functional interplay introduces substantial complexity.In this study,we employed one-pot technology to build a post-transcriptional regulatory component(PTRC)library of 576 variants to clarify the relationship between sequence variants and both protein expression and mRNA levels via high-throughput sequencing.Our results show that although unstructured TSSs do not enhance mRNA stability,they markedly increase translation efficiency,causing a 16%–100%rise in protein expression.In contrast,structured TSSs increase mRNA levels by 43%–90%.Additionally,highly conserved SD sequences boost translation efficiency by up to 10%and mRNA abundance by up to 12%.Moreover,it was found that optimized linear N-terminal coding sequence(NCS)positively affects protein expression and mRNA levels.The effects of these optimized regulatory components were verified in the expression control of the nrk and sam2 genes,resulting in enhanced production.These findings underscore the crucial role of structural optimization,guiding the rational design of synthetic post-transcriptional regulatory elements. 展开更多

In this study,FeCrxMnAlCu(x=0,0.5,1.0,1.5,2.0)high-entropy alloys were fabricated using vacuum arc melting,and the corrosion behavior of these alloys in 3.5wt%NaCl solution at room temperature was investigated by electrochemical dynamic potential polarization curves and immersion experiments.The microstructure results show that the high-entropy alloy with x=0 has a body-centered cubic phase structure,whereas the high-entropy alloys with x=0.5–2.0 have a mixed face-centered cubic+body-centered cubic dual-phase structure.The corrosion results show that the corrosion resistance of the high-entropy alloy is increased with the increase in Cr content.Among them,the high-entropy alloy with x=2.0 exhibits the optimal corrosion resistance:the highest self-corrosion potential(Ecorr=−0.354 V vs.Ag/AgCl),the smallest self-corrosion current density(Icorr=1.991×10−6A·cm−2),and the smallest corrosion rate(0.0292 mm/a).The composite passivation film of oxides and hydroxides is formed on the surface of the corroded high-entropy alloys,and the Cr2O3content is increased with the increase in Cr content,which effectively improves the stability and protective properties of the passivation film. 展开更多

In this paper,we prove the global existence of strong solutions to a two-dimensional(2D)Keller-Segel-Navier-Stokes system with subcritical sensitivity in a bounded domain.Using energy methods,interpolation inequalities and the Gronwall lemma,we establish uniform a priori estimates for the solutions.We prove the existence and uniqueness of global strong solutions under appropriate initial conditions,along with higher-order Sobolev regularity of solutions.The result extends existing conclusions and enriches the global wellposedness theory for chemotaxis-fluid coupled models. 展开更多
