Theα-GeTe is a typical ferroelectric Rashba semiconductor(FERSC)that has attracted a lot of attention in spintronics.The Fe/α-GeTe grown on Si substrates has anisotropic Gilbert damping.However,the effect of Al2O3,as another common substrate,remains unknown whenα-GeTe is grown on it.Here,we fabricatedα-GeTe thin films using Al2O3substrates.Theα-GeTe directly grown on Al2O3exhibits an in-plane polycrystalline structure.A Bi2Te3buffer layer can make theα-GeTe exhibit a single-crystal feature.The anisotropic Gilbert damping of FM layers is present in Fe/α-GeTe/Bi2Te3/Al2O3and vanished in Fe/α-GeTe/Al2O3.Our finding illustrates thatα-GeTe growth on Al2O3with a Bi2Te3buffer layer can serve as a suitable platform for anisotropic research.Our work paves the way for the application of the Al2O3-basedα-GeTe thin films in anisotropic electronics. 展开更多

Compacted bentonite blocks are proposed for buffer barriers in deep geological repositories for high-level radioactive waste(HLRW)disposal.These blocks,manufactured through uniaxial compression in molds,exhibit heterogeneity that may impact long-term buffer performance.This study focuses on the physical and hydro-mechanical heterogeneity of full-scale blocks induced by the compaction process.Sector-shaped blocks,with radii of 600 mm and 1200 mm and a height of 200 mm,were axially compressed.Key parameters,including water content,dry density,elasticity modulus,swelling pressure,and permeability,were measured to assess the heterogeneity.Results show that the heterogeneity in the upper layer is primarily caused by differences in drainage and gas expulsion pathways.As depth increases,water content and dry density become more correlated.Hydro-mechanical behavior is largely controlled by dry density,but its fluctuation ratio is much higher than that of dry density.Regarding the microstructure,pore structure heterogeneity follows the order:corner regions>edge regions>center regions,and upper layer>middle layer>lower layer.Vertical microcracks also develop to varying degrees,increasing the anisotropy of the blocks.Upon these observations,the study thoroughly discusses the feasibility and challenges of reckoning the hydro-mechanical properties of blocks using dry density distribution alongside laboratory-scale data.Additionally,it proposes an indicator to evaluate the overall heterogeneity of buffer blocks.These findings highlight the inherent heterogeneity of compacted bentonite blocks at the engineering scale,providing valuable insights for future experiments and simulations. 展开更多

The pseudo-planar heterojunction(PPHJ)structure obtained via layer-by-layer(LBL)deposition offers a promising pathway for efficient and stable organic solar cells(OSCs);however,solvent-induced swelling and erosion of the donor layer during acceptor deposition often hinder the formation of an ideal vertical phase separation(VPS)morphology.Here,a simple approach for incorporating a highly crystalline polymer as a buffer layer between the donor and acceptor layers is proposed.We investigated the effectiveness of this strategy by constructing three systems:PM6/L8-BO,PM6:D18/L8-BO,and PM6/D18/L8-BO.Compared with the other two systems,when deposited as a separate layer,D18 with low surface energy forms a dense crystalline fibrillar network,effectively suppressing L8-BO over-penetration and mitigating chloroform-induced PM6 erosion.This architecture achieves the most favorable VPS morphology with an improved donor/acceptor gradient distribution and higher phase purity,facilitating charge transport and suppressing recombination.Moreover,the D18 buffer layer can regulate molecular packing,improve active layer crystallinity,and passivate interfacial defects to reduce energy loss.Consequently,the PM6/D18/L8-BO-based device achieved a superior power conversion efficiency(PCE)of 19.80%.Notably,integrating BTP-e C9 further increased the PCE to 20.21%.This study demonstrates that introducing a highly crystalline polymer as a p-i-n buffer layer can effectively optimize the VPS morphology,enabling highperformance PPHJ OSCs. 展开更多

Comprehending coupled thermo-hydro-mechanical(THM)processes in geomaterials is essential for addressing various geoenvironmental problems.Predicting the THM response of bentonite buffers in nuclear waste repositories(NWRs)requires accounting for temperature-sensitive hydraulics that affect swelling behaviour.In this study,a temperature-dependent soil water retention curve(SWRC)model was formulated to attain an implicit thermo-hydraulic coupling in the THM governing equations.Furthermore,a parameter-sensitivity study was conducted to investigate the influence of the SWRC fitting parameters on the bentonite's water retention capacity.Building on this constitutive law,the study developed a simplified,rigorous THM framework that augments Richards'flow equation with explicit vapour diffusion,employs the developed non-isothermal SWRC relation and temperature-dependent fluid properties to characterise the bentonite's hydration response at elevated temperatures,and couples hydraulics to the Extended Barcelona Basic Model(BBMx)to predict suction-driven swelling pressures.The performance of the proposed framework was demonstrated through two numerical scenarios:(i)a laboratory-scale domain with a simplified representation of NWR conditions under coupled thermo-hydraulic gradients,and(ii)an isothermal scenario focused on evaluating swelling pressures.Results revealed that incorporating non-isothermal hydraulic constitutive relationships improved suction predictions and precisely corroborated experimental relative humidity data.The thermal dependence of the SWRC was identified as the key sensitive parameter governing the hydraulic flow and mechanical behaviour.Neglecting thermal effects led to an overestimation of swelling pressure,underscoring the importance of thermal-hydraulic interactions in governing the mechanics.The proposed formulation captured the THM behaviour with accuracy comparable to complex two-phase models,with significantly lower computational demands,making it adaptable to other geoenvironmental systems. 展开更多

The squeezing deformation of surrounding rock is an important factor restricting the safe construction and long-term operation of tunnels when a tunnel passes through soft strata with high ground stress.Under such soft rock geological conditions,the large deformation of the surrounding rock can easily lead to the failure of supporting structures,including shotcrete cracks,spalling,and steel arch distortion.To improve the lining support performance during the large deformation of squeezed surrounding rock,this work selects aluminum foam with densities of 0.25 g/cm3,0.42 g/cm3 and 0.61 g/cm3 as the buffer layer material and carries out uniaxial confined compression tests.Through the evaluation and analysis of energy absorption and the comparison of the yield pressure of aluminum foam with those of other cushioning materials and yield pressure support systems,the strength,deformation and energy absorption of aluminum foam with a density of 0.25 g/cm3 meet the yield pressure performance requirements.The numerical model of the buffer layer yielding support system is then established via the finite element analysis software ABAQUS,and the influence of the buffer layer setting on the lining support is analyzed.Compared with the conventional support scheme,the addition of an aluminum foam buffer layer can reduce the stress and deformation of the primary support and secondary lining.The maximum and minimum principal stresses of the primary support are reduced by 13%and 15%,respectively.The maximum and minimum principal stresses of the secondary lining are reduced by 15%and 12%,respectively,and the displacement deformation of the secondary lining position is reduced by 15%.In summary,the application of aluminum foam buffer layer can reduce the stress and deformation of the primary support and secondary lining,improve the stress safety of the support and reduce the deformation of the support. 展开更多

Temperate forests exert significant biogeophysical influences on local and regional climates through modulating the energy and moisture exchanges between the land surface and the atmosphere,thereby serving as crucial barriers with significant buffering impacts on the productivity of adjacent agricultural ecosystems.However,the extent and underlying mechanisms of these biogeophysical and buffering effects of temperate forest barriers remains insufficiently understood.In this study,we integrated the dynamic crop model Noah-MP-Crop with the Weather Research and Forecasting(WRF)model to investigate the biogeophysical climate regulation of temperate forests and its buffering effects on crop yields in adjacent agricultural lands across Northeast China.Our findings revealed that temperate forest barriers induced significant local climate effects by cooling air and surface temperatures and reducing wind speeds within forested areas during the growing season,while also regulating non-local climate,particularly by altering regional precipitation patterns,2 m water vapor mixing ratio(Q2),and soil moisture,predominantly in adjacent cropland areas.Furthermore,these forest barriers were found to modulate climate extremes,through affecting maximum temperature and wind speed on a local scale,as well as both maximum and minimum Q2 in non-local croplands.Our study also observed that temperate forest barriers,through biogeophysical climate regulation,enhanced GPP,NPP,and grain yields across most cropland areas.This productivity boost was especially pronounced,with yield increases up to 20%in certain regions during the extreme drought conditions of 2017,underscoring the critical role of temperate forest barriers in sustaining and enhancing crop yields under severe climatic stress.Our findings underscore the significant buffering effects of temperate forest barriers on regional agricultural production,having important implications for climate adaptation strategies aimed at bolstering agricultural resilience in the face of increasing climate variability and extremes. 展开更多

Maglev trains experience significant aerodynamic effects when passing through tunnels.A moving model test was conducted to explore the practical effects of speed reduction and entrance buffer structures on mitigating tunnel/maglev aerodynamic effects.It is found that both have an overall positive effect on mitigating the aerodynamic environment inside and outside the tunnel.Trains operating at 200 km/h show a 49.8%decrease in peak-to-peak pressure and a 50.7%decrease in transient pressure instability on inner walls compared to those at 280 km/h.Lower speeds resulted in a 65.6%decrease in amplitude and a 24.5%decrease in decay rate,both of which are parameters for exponential fittings of pressure peaks that decay naturally after the train leaves.The buffer structures result in a reduction of up to 25.7%in the maximum positive pressure and a 29.0%decrease in transient pressure instability.Additionally,a reduction in amplitude of up to 21.2%and a 32.2%increase in decay rate were observed with the use of buffer structures.Nevertheless,it is difficult to conclude direct correlations between the maximum pressure,peak-to-peak values,etc.,and the speeds or buffer structures due to the complex wave propagation in tunnels.However,speed reduction and buffer structures are proven to be effective in reducing the micro-pressure wave levels with a simpler monotonic relationship. 展开更多

Photocatalytic hydrogen peroxide(H2O2)production offers a sustainable route to convert water and oxygen into H2O2using solar energy.However,achieving long-term stability in photocatalysts remains a critical challenge due to mismatched kinetics between oxygen reduction(ORR)and water oxidation(WOR),which leads to hole accumulation and oxidative degradation.Here,we report a redox-mediated strategy to address this bottleneck by designing a hydroquinone-embedded covalent organic framework(Tz-QH-COF)that enables reversible hole buffering and kinetic balance.The hydroquinone(QH)units act as dynamic hole reservoirs,capturing excess holes during ORR and converting to benzoquinone(Q),which is regenerated to QH via WOR,thereby preventing oxidative decomposition.This reversible QH/Q cycle,directly visualized through in situ attenuated total reflection surface-enhanced infrared absorption spectroscopy,ensures unmatched stability,achieving continuous H2O2 production for 528 h(22 d)with an accumulated yield of 18.6 mmol L–1—the highest reported duration for organic photocatalysts.Density functional theory calculations reveal that the QH units exhibit a strong oxygen adsorption energy and favorable two-electron ORR/WOR pathways with low energy barriers.The synergy between experimental and theoretical insights elucidates a redox-mediated charge-balance mechanism,advancing the design of robust photocatalysts for solar-driven H2O2 synthesis. 展开更多

Optimizing the orientation of β-Ga2O3 has emerged as an effective strategy to design high-performance β-Ga2O3 device,but the orientation growth mechanism and approach have not been revealed yet.Herein,by employing AlN buffer layer,the highly preferred orientation of β-Ga2O3(100)film rather than(-201)film is realized on 4H-SiC substrate at low sputtering power and temperature.Because β-Ga2O3(100)film exhibits a slower growth speed than(-201)film,the former possesses the higher dangling bond density and the lower nucleation energy,and a large conversion barrier exists between these two ori-entations.Moreover,the AlN buffer layer can suppress the surface oxidation of the 4H-SiC substrate and eliminate the strain of β-Ga2O3(100)film,which further reduces the nucleation energy and en-larges the conversion barrier.Meanwhile,the AlN buffer layer can increase the oxygen vacancy formation energy and decrease the oxygen vacancy concentration of β-Ga2O3(100)film.Consequently,the solar-blind photodetector based on the oriented film exhibits the outstanding detectivity of 1.22×1012 Jones and photo-to-dark current ratio of 1.11×105,which are the highest among the reported β-Ga2O3 solar-blind photodetector on the SiC substrate.Our results offer in-depth insights into the preferred orientation growth mechanism,and provide an effective way to design high-quality β-Ga2O3(100)orientation film and high-performance solar-blind photodetector. 展开更多

Attempts to remove environmentally harmful materials in mass production industries are always a major issue and draw attention if the substitution guarantees a chance to lower fabrication cost and to improve device performance,as in a wide bandgap Zn1-xMgxO(ZMO)to replace the CdS buffer in Cu(In1-x,Gax)Se2(CIGSe)thin-film solar cell structure.ZMO is one of the candidates for the buffer material in CIGSe thin-film solar cells with a wide and controllable bandgap depending on the Mg content,which can be helpful in attaining a suitable conduction band offset.Hence,compared to the fixed and limited bandgap of a CdS buffer,a ZMO buffer may provide advantages in Voc and Jsc based on its controllable and wide bandgap,even with a relatively wider bandgap CIGSe thin-film solar cell.In addition,to solve problems with the defect sites at the ZMO/CIGSe junction interface,a few-nanometer ZnS layer is employed for heterojunction interface passivation,forming a ZMO/ZnS buffer structure by atomic layer deposition(ALD).Finally,a Cd-free all-dry-processed CIGSe solar cell with a wider bandgap(1.25 eV)and ALD-grown buffer structure exhibited the best power conversion efficiency of 19.1%,which exhibited a higher performance than the CdS counterpart. 展开更多

Aqueous zinc-ion batteries(AZIBs)have developed rapidly in recent years but still face several challenges,including zinc dendrites growth,hydrogen evolution reaction,passivation and corrosion.The pH of the electrolyte plays a crucial role in these processes,significantly impacting the stability and reversibility of Zn2+deposition.Therefore,pH-buffer tris(hydroxymethyl)amino methane(tris)is chosen as a versatile electrolyte additive to address these issues.Tris can buffer electrolyte pH at Zn/electrolyte interface by protonated/deprotonated nature of amino group,optimize the coordination environment of zinc solvate ions by its strong interaction with zinc ions,and simultaneously create an in-situ stable solid electrolyte interface membrane on the zinc anode surface.These synergistic effects effectively restrain dendrite formation and side reactions,resulting in a highly stable and reversible Zn anode,thereby enhancing the electrochemical performance of AZIBs.The Zn||Zn battery with 0.15 wt%tris additives maintains stable cycling for 1500 h at 4 mA·cm−2 and 1120 h at 10 mA·cm−2.Furthermore,the Coulombic efficiency reaches~99.2%at 4 mA·cm−2@1 mAh·cm−2.The Zn||NVO full batteries also demonstrated a stable specific capacity and exceptional capacity retention. 展开更多

The shop scheduling problem with limited buffers has broad applications in real-world production scenarios,so this research direction is of great practical significance.However,there is currently little research on the hybrid flow shop scheduling problem with limited buffers(LBHFSP).This paper deeply investigates the LBHFSP to optimize the goal of the total completion time.To better solve the LBHFSP,a multi-level subpopulation-based particle swarm optimization algorithm(MLPSO)is proposed,which is founded on the attributes of the LBHFSP and the shortcomings of the basic PSO(particle swarm optimization)algorithm.In MLPSO,firstly,considering the impact of the limited buffers on the process of subsequent operations,a specific circular decoding strategy is developed to accommodate the characteristics of limited buffers.Secondly,an initialization strategy based on blocking time is designed to enhance the quality and diversity of the initial population.Afterward,a multi-level subpopulation collaborative search is developed to prevent being trapped in a local optimum and improve the global exploration capability.Additionally,a local search strategy based on the first blocked job is designed to enhance the MLPSO algorithm’s exploitation capability.Lastly,numerous experiments are carried out to test the performance of the proposed MLPSO by comparing it with classical intelligent optimization and popular algorithms in recent years.The results confirm that the proposed MLPSO has an outstanding performance when compared to other algorithms when solving LBHFSP. 展开更多

The Casimir pressure plays an important role in the adhesion stability of nanofilms at submicro scales.In this work,the Casimir pressure of peptide films deposited on a layered substrate is investigated.Three types of semi-infinite substrates,i.e.,silica,silicon and gold,are considered.The buffer layer between the peptide film and substrate consists of silicon or silica.The switching sign of the Casimir pressure can be controlled in a region ranging from about 130 nm to 1000 nm,depending on the thickness of the buffer layer and the substrate.The results suggest that the critical thickness of peptide films for Casimir equilibrium increases(or decreases)by increasing the thickness of the silicon(or silica)buffer film.The influences of wetting and electrolyte screening on the Casimir pressure are also investigated.Our finding provides a theoretical guide for the adhesion stability of peptide films in organic electronics. 展开更多

Man-made superheavy elements(SHE)are produced as energetic recoils in complete-fusion reactions and need to be thermalized in a gas-filled chamber for chemical studies.The ever-shorter half-lives and decreasing production rates of the elements beyond Fl(atomic number Z=114)-the heaviest element chemically studied today-require the development of novel techniques for quantitative thermalization and fast extraction efficiency.The Universal high-density gas stopping Cell(UniCell),currently under construction,was proposed to achieve this.Within this work,we propose an Ion Transfer by Gas Flow(ITGF)device,which serves as a UniCell ejector to interface with a gas chromatography detector array for chemical studies.Detailed parameter optimizations,using gas dynamics and Monte Carlo ion-trajectory simulations,promise fast(within a few ms)and highly efficient(up to 100%)ion extraction across a wide mass range.These ions can then be transmitted quantitatively through the ITGF into the high-pressure environment needed for further chemical studies. 展开更多

Stochastic optical reconstruction microscopy(STORM),as a typical technique of single-molecule localization microscopy(SMLM),has overcome the diffraction limit by randomly switching fluorophores between fluorescent and dark states,allowing for the precise localization of isolated emission patterns and the super-resolution reconstruction from millions of localized positions of single fluorophores.A critical factor influencing localization precision is the photo-switching behavior of fluorophores,which is affected by the imaging buffer.The imaging buffer typically comprises oxygen scavengers,photo-switching reagents,and refractive index regulators.Oxygen scavengers help prevent photobleaching,photo-switching reagents assist in facilitating the conversion of fluorophores,and refractive index regulators are used to adjust the refractive index of the solution.The synergistic interaction of these components promotes stable blinking of fluorophores,reduces irreversible photobleaching,and thereby ensures high-quality super-resolution imaging.This review provides a comprehensive overview of the essential compositions and functionalities of imaging buffers used in STORM,serving as a valuable resource for researchers seeking to select appropriate imaging buffers for their experiments. 展开更多

To detect the genome of viruses (in environmental and clinical samples), we use electrophoresis running buffer after PCR reaction. Also, electrophoresis buffers were used widely to separate any DNA molecule. In this paper, we used four types of previously known electrophoresis buffers to compare which is easy for preparation, simple in structure, low cost and good performance in agarose gel electrophoresis. For this, we used two agarose concentration (1%, 2%) and two types of DNA ladder (100 bp, 1 kb) represent both smaller and larger sizes of molecule for each type of buffers, from the result we found in first level both supper buffer and TAE buffer with good performance and in second level we found bicarbonate buffer also with good performance also. Finally, we found the tang buffer cannot pose any electrophoretic activity on DNA agarose gel electrophoresis. 展开更多

The buffer zone of a World Natural Heritage Site constitutes a critical element of the heritage site protection system.It not only functions as an ecological security barrier,but also significantly influences the visual integrity and aesthetic value of the core area’s landscape.Given the rapid development of transportation infrastructure,particularly the growing number of high-speed railways traversing ecologically sensitive regions,the scientific assessment of their impact on the landscape environment of heritage sites has emerged as a pivotal concern in heritage conservation and regional development.This study focused on the section of the Guiyang-Nanning High-Speed Railway that traverses the buffer zone of the Libo World Natural Heritage Site in Guizhou Province.Beginning with five primary indicators,including natural landscape and aesthetic value,geological geomorphology and Earth history value,biodiversity value,integrity and protection management,and impact on ecological environment,a visual landscape impact assessment system for high-speed railways was developed based on the analytic hierarchy process(AHP)and the fuzzy comprehensive evaluation method(FCE).Through expert scoring,hierarchical weight calculation,and fuzzy membership degree analysis,a comprehensive assessment was conducted on the landscape ecological quality,visual coordination,and aesthetic perception within the buffer zone following the construction of high-speed railways.The findings indicate that the construction of the Guiyang-Nanning High-Speed Railway generally harmonizes well with the landscape environment of the heritage site.The level of visual disturbance remains within an acceptable range and has not significantly damaged the overall aesthetic value or authenticity of the heritage site.Although the integrity of the landscape in certain local areas has experienced a slight decline due to the exposure of bridge and slope structures,the adverse effects have been effectively mitigated through engineering interventions such as vegetation restoration and color coordination.This study innovatively integrates the AHP with fuzzy mathematics methods to achieve a comprehensive evaluation that combines both qualitative and quantitative approaches.This integration provides a scientifically grounded analytical path and a practical technical framework for assessing the visual impact of linear infrastructure projects,such as high-speed railways,within the buffer zones of World Heritage Sites.The findings offer valuable insights for the protection of landscapes and the sustainable development of infrastructure in heritage sites. 展开更多

To reveal the relationship between a weakening buffer operator and strengthening buffer operator, the traditional integer order buffer operator is extended to one that is fractional order. Fractional order buffer operator not only can generalize the weakening buffer operator and the strengthening buffer operator, but also results in small adjustments of the buffer effect.The effectiveness of the grey model(GM(1,1)) with the fractional order buffer operator is validated by six cases. 展开更多

Steam networks offer a practical solution to increase flexibility in energy-intensive industries,thanks to their potential for electrification and integration of various energy sources.However,effectively using this flexibil-ity requires models that accurately represent system constraints and dynamics for control.While first-principle models provide accuracy,their complexity can hinder practical control applications.This paper proposes a data-driven model using Generic Buffer to model the intrinsic flexibility and dynamics of a steam network in order to efficiently leverage the available flexibility through model predictive control.The simulations show signifi-cant weekly reductions in CO2 emissions(between 8630 and 13780 tCO2)with an emissions-oriented controller,and in costs(between 29 and 1860 kEUR)with a cost-oriented controller,compared to a pressure-regulating proportional-integral(PI)controller. 展开更多
