Tungsten-copper laminated composites are promising materials for high heat-flux applications,but their performance is often limited by interfacial instability caused by the thermal-mechanical mismatch between tungsten and copper.In this study,W/W-30Cu/CuCrZr three-layer composites are fabricated by high-pressure torsion(HPT)processing.Experimental characterization and molecular dynamics(MD)simulations are used to systematically investigate the influence of HPT process parameters and intermediate-layer composition on the evolution of microstructure and mechanical properties.HPT processing significantly refines the grains of the W-xCu composites and enhances their homogeneity.After applying 15 revolutions of HPT on W-30Cu composites,the crystallite size decreases by about 45.3%.The dislocation density increases to 5.95×1014 m−2.The interfacial transition zone of tungsten-copper three-layer composites is continuous and stable after HPT processing,and the microhardness is gradient increasing along the radial direction,showing good stress coordination ability and interfacial bonding characteristics.With the increase of W content,the yield strength of W-xCu alloy increases significantly,but the ductility decreases.The W-30Cu system achieves the optimal balance between strength and ductility.At the same time,in the W/W-Cu/Cu model,as the number of dislocations increases,the yield stress and elastic modulus increase by about 15%and 22%,respectively,indicating that the high-density defects introduced by HPT have a significant strengthening effect on the composite system.This study provides an important theoretical basis and experimental support for the microstructure control and performance optimization of tungsten-copper laminated composite material. 展开更多

Constrained friction processing(CFP)is an innovative technique for lightweight materials,producing fine or ultrafine microstructures through severe plastic deformation.CFP favors the formation of ultrastrong B-fiber texture in rods of Mg alloys,with its orientations varying along the rod according to the local material flow conditions.This study aims to investigate the local micromechanical behavior of AM50 rods produced via CFP and the deformation mechanisms under tensile loading specific to each analyzed position.For this purpose,a combined analysis of local microstructure and microindentation was performed,followed by tensile testing of micro-flat specimens taken at three rod positions,i.e.center and edge along the plunge direction,and middle along the radial direction,in order to investigate the role of grain size and texture on the local deformation mechanisms,and ultimately,the local mechanical properties.The results indicate that texture has a more dominant influence than grain size on the local mechanical behavior of rods processed via CFP given the pronounced gradient of ultrastrong textures observed along the rod radius,which determines the dominant deformation mechanisms.Furthermore,an approach using quasi-in-situ tensile tests performed at the center of the rod indicates that slip and tensile twinning are the main deformation modes for the ultrastrong B-fiber texture observed at this position.In contrast,at the middle of the rod,the deformation of the local ultrastrong basal texture is ruled by basal slip,combined to the slip transfer.An exceptional enhancement in elongation at break(≈49%)is observed in the sample taken at the edge of the rod,with an ultrastrong B-fiber texture tilted 25°in relation to the center.This is attributed to a combination of lattice rotation,which aligns the basal planes at 45°to the tensile axis,and the maximized activity of basal slip. 展开更多

[Objectives]To establish a high-performance liquid chromatography(HPLC)method for comparing the content differences of xanthopurpurin in raw Rubia cordifolia and its charred products processed at different temperatures,sourced from various regions.[Methods]The chromatographic separation was performed using an HPLC Column C 18.The mobile phase consisted of acetonitrile-0.2%phosphoric acid solution(50:50,v/v)at a flow rate of 1.0 mL/min.Detection was carried out at 245 nm,and the column temperature was maintained at 30℃.[Results]Xanthopurpurin exhibited a good linear relationship within the range of 6.712-83.905μg/mL(r=1.0000).The average recovery rate was 101.3%with an RSD of 2.1%(n=6).Content determination results showed that the xanthopurpurin content in raw R.cordifolia ranged from 0.0400 to 0.1693 mg/g.In charred R.cordifolia processed at 110-130℃,it ranged from 0.3092 to 0.3801 mg/g,while in charred R.cordifolia processed at 350-370℃,it ranged from 0.5128 to 1.1688 mg/g.A significant increasing trend in xanthopurpurin content was observed with rising charring temperatures.[Conclusions]This method is simple,accurate,feasible,and reproducible.It can effectively distinguish between raw R.cordifolia and its charred products processed at different temperatures,providing a scientific basis for the quality evaluation of charred R.cordifolia and its formulations in traditional Chinese medicine. 展开更多

High entropy alloys(HEAs)have recently attracted significant attention due to their exceptional mechanical properties and potential applications across various fields.Friction stir welding and processing(FSW/P),as notable solid-state welding and processing techniques,have been proved effectiveness in enhancing microstructures and mechanical properties of HEAs.This review article summarizes the current status of FSW/P of HEAs.The welding materials and conditions used for FSW/P in HEAs are reviewed and discussed.The effects of FSW/P on the evolutions of grain structure,texture,dislocation,and secondary phase for different HEAs are highlighted.Furthermore,the influences of FSW/P on the mechanical properties of various HEAs are analyzed.Finally,potential applications,challenges,and future directions of FSW/P in HEAs are forecasted.Overall,FSW/P enable to refine grains of HEAs through dynamic recrystallization and to activate diverse deformation mechanisms of HEAs through tailoring phase structures,thereby significantly improving the strength,hardness,and ductility of both single-and dual-phase HEAs.Future progress in this field will rely on comprehensive optimization of processing parameters and alloy composition,integration of multi-scale modeling with advanced characterization for in-depth exploration of microstructural mechanisms,systematic evaluation of functional properties,and effective bridging of the gap between laboratory research and industrial application.The review aims to provide an overview of recent advancements in the FSW/P of HEAs and encourage further research in this area. 展开更多

Two-step-processed(TSP)inverted p-i-n perovskite solar cells(PSCs)have demonstrated significant promise in tandem applications.However,the power conversion efficiency(PCE)of TSP p-i-n PSCs rarely exceeds 24%.Here,we demonstrate that TSP perovskite films exhibit a vertically gradient distribution of residual PbI2clusters,which form Schottky heterojunctions with the perovskite,leading to substantial interfacial energy-level mismatches within NiOx-based TSP p-i-n PSCs.These limitations were effectively addressed via a vertical interfacial engineering enabled by dual-interface modification incorporating tin trifluoromethanesulfonate(Sn(OTF)2)and 4-Fluorophenylethylamine chloride(F-PEA)at the NiOx/perovskite and perovskite/C60 interfaces,respectively.The functional Sn(OTF)2not only enhances the conductivity of NiOxfilms but also suppresses ion migration,while inducing the formation of a Pb-Sn mixed perovskite interlayer that precisely regulates the energy level at the NiOx/perovskite interface.Complementally,F-PEA post-treatment effectively converts surface residual PbI2clusters into a 2D perovskite capping layer,which simultaneously passivates surface defects and enhances energy-level alignment at the perovskite/C60 interface.Consequently,the optimized NiOx-based TSP p-i-n PSCs achieve a notable PCE of 25.6%with superior operational stability.This study elucidates the underlying mechanisms limiting the efficiency of TSP p-i-n PSCs,while establishing design principles for these devices targeting 26%efficiency. 展开更多

Bone repair remains an important target in tissue engineering,making the development of bioactive scaffolds for effective bone defect repair a critical objective.In this study,β-tricalcium phosphate(β-TCP)scaffolds incorporated with processed pyritum decoction(PPD)were fabricated using three-dimensional(3D)printing-assisted freeze-casting.The produced composite scaffolds were evaluated for their mechanical strength,physicochemical properties,biocompatibility,in vitro proangiogenic activity,and in vivo efficacy in repairing rabbit femoral defects.They not only demonstrated excellent physicochemical properties,enhanced mechanical strength,and good biosafety but also significantly promoted the proliferation,migration,and aggregation of pro-angiogenic human umbilical vein endothelial cells(HUVECs).In vivo studies revealed that all scaffold groups facilitated osteogenesis at the bone defect site,with theβ-TCP scaffolds loaded with PPD markedly enhancing the expression of neurogenic locus Notch homolog protein 1(Notch1),vascular endothelial growth factor(VEGF),bone morphogenetic protein-2(BMP-2),and osteopontin(OPN).Overall,the scaffolds developed in this study exhibited strong angiogenic and osteogenic capabilities both in vitro and in vivo.The incorporation of PPD notably promoted the angiogenic-osteogenic coupling,thereby accelerating bone repair,which suggests that PPD is a promising material for bone repair and that the PPD/β-TCP scaffolds hold great potential as a bone graft alternative. 展开更多

Background The increasing consumption of fast foods(FFs)and ultra-processed foods(UPFs)worldwide has raised concerns due to their association with carcinogenic compounds and potential links to various cancers.However,this evidence about breast cancer risk remains inconsistent.This study aimed to meta-analyze the association between FFs and UPFs consumption and the risk of breast cancer in females.Methods A comprehensive search on online databases was conducted from inception to May 2025,and relevant study data were extracted.The meta-analysis utilized odds ratio(OR)with 95%confidence interval(CI)as effect size measures.Subgroup analyses,heterogeneity assessment,publication bias,and sensitivity analyses were performed to ensure robustness.All statistical analyses were conducted using STATA.Results The pooled analysis of 17 observational studies showed a significant association between the highest FFs and UPFs consumption and increased breast cancer risk(OR 1.25,95%CI[1.09-1.43],p=0.001).Subgroup analysis revealed a significant positive association between FFs and UPFs consumption and breast cancer risk in case-control studies,but not in cohort studies or menopausal status and a significant association was observed in studies with sample sizes>1000 and<1000.Furthermore,the association was significant in Latin America when BMI adjustment was considered for'yes'and'no'.Conclusions This meta-analysis identified a significant association between the consumption of FFs and UPFs and an increased risk of breast cancer,with high intake linked to a 25%greater risk.These findings suggest that diets high in UPFs may play a role in breast cancer development.As UPF consumption continues to rise,public health strategies and regulatory policies targeting food processing,marketing,labeling,and accessibility are essential for cancer risk reduction and prevention. 展开更多

Acrylamide(AA)is a neurotoxin and carcinogen that formed during the thermal food processing.Conventional quantification techniques are difficult to realize on-site detection of AA.Herein,a flower-like bimetallic FeCu nanozyme(FeCuzyme)sensor and portable platform were developed for naked-eye and on-site detection of AA.The FeCuzyme was successfully prepared and exhibited flower-like structure with 3D catalytic centers.Fe/Cu atoms were considered as active center and ligand frameworks were used as cofactor,resulting in collaborative substrate-binding features and remarkably peroxidase-like activity.During the catalytic process,the 3,3′,5,5′-tetrame-thylbenzidine(TMB)oxidation can be quenched by glutathione(GSH),and then restored after thiolene Michael addition reaction between GSH and AA.Given the“on–off–on”effect for TMB oxidation and high PODlike activity,FeCuzyme sensor exhibited a wide linear relationship from 0.50 to 18.00μM(R2=0.9987)and high sensitivity(LOD=0.2360μM)with high stability.The practical application of FeCuzyme sensor was successfully validated by HPLC method.Furthermore,a FeCuzyme portable platform was designed with smartphone/laptop,and which can be used for naked-eye and on-site quantitative determination of AA in real food samples.This research provides a way for rational design of a novel nanozyme-based sensing platform for AA detection. 展开更多

Friction stir processing(FSP)induces severe plastic deformation,generating intense strains and localized heating,which modifies the surface and enables the fabrication of magnesium(Mg)-based composites.This technique refines the microstructure of Mg alloys,enhancing mechanical properties—particularly ductility,a key limitation of these HCP alloys.This review addresses the underlying microstructural evolution during FSP of Mg alloys and Mg-matrix composites,including(i)grain refinement via continuous and discontinuous dynamic recrystallization(CDRX and DDRX),(ii)fragmentation and redistribution of secondary phases and intermetallics,(iii)transformation of low-and high-angle grain boundaries,and(iv)additional microstructural changes induced by external reinforcements.This review provides a comprehensive analysis of the strengthening mechanisms and their impact on the mechanical properties of FSP Mg alloys and Mgmatrix composites(MMCs).The paper examines the correlation between FSP processing parameters,microstructural evolution,and resulting mechanical properties.It critically highlights how the type of reinforcement and the dynamic recrystallization induced by friction stir processing influence grain boundary character and,consequently,the material’s strengthening response.It includes a comparative evaluation of yield stress,ultimate tensile strength,microhardness,elongation,and fractography for various FSP-treated Mg alloys and MMCs,including AZxx,WExx,ZExx,ZKxx,AMxx,AExx,and Mg-rare earth alloys.Additionally,the novelty of this review lies in its emphasis on connecting microstructural transformations to mechanical performance trends across different alloy systems and processing strategies,an aspect that has been underexplored in previous reviews.Recent advancements in FSP techniques and their implications for improving the performance of Mg-based materials are also discussed. 展开更多

In this study,friction stir processing(FSP)was employed to modify the as-cast Mg-14Gd-0.6Ce-0.5Zr alloy,and the effects of texture evolution and distribution of second phases on mechanical properties were systematically investigated.The results show that friction stir processing effectively refined the coarse Mg5Gd phases into nanoscale second phases uniformly distributed along grain boundaries.The synergistic effect of texture weakening and second phases refinement significantly enhanced the tensile strength and elongation of the FSP-1000-120 alloy to 302.1 MPa and 18.3%,respectively,representing increases of 20.8%and 281.3%compared to the as-cast alloy.The as-cast alloy has a lower corrosion rate in the initial stage due to fewer micro-galvanic corrosion sites.However,the uniform distribution of the second phase in the FSP-treated(FSPed)alloy contributes to the formation of a more complete and dense corrosion product film.After 120 h of immersion,the as-cast alloy forms deep pits due to the continuous dissolution at the second phase-matrix interface,with the average corrosion rate increasing from 0.31 to 0.47 mL/cm2/h.The long-term corrosion rates of FSP-1000-60,FSP-1000-120,and FSP-1200-120 samples are stable at 0.36,0.43,and 0.50 mL/cm2/h,respectively.Research reveals that FSP regulates texture and second phase distribution to achieve synergistic strengthening of alloy strength plasticity,and the homogenization of second phase distribution is a key factor in improving the long-term corrosion resistance of alloys. 展开更多

Aconiti Lateralis Radix Praeparata(Fuzi)represents a significant traditional Chinese medicine(TCM)that exhibits both notable pharmacological effects and toxicity.Various processing methods are implemented to reduce the toxicity of raw Fuzi by modifying its toxic and effective components,primarily diterpenoid alkaloids.To comprehensively analyze the chemical variations between different Fuzi products,ultra-high performance liquid chromatography-linear ion trap quadrupole Orbitrap mass spectrometry(UHPLC-LTQ-Orbitrap MS)was employed to systematically characterize Shengfuzi,Heishunpian and Baifupian.A total of 249 diterpenoid alkaloids present in Shengfuzi were identified,while only 111 and 61 in Heishunpian and Baifupian were detected respectively,indicating substantial differences among these products.An untargeted metabolomics approach combined with multivariate statistical analysis revealed 42 potential chemical markers.Through subsequent validation using 52 batches of commercial Heishunpian and Baifupian samples,8 robust markers distinguishing these products were identified,including AC1-propanoic acid-3OH,HE-glucoside,HE-hydroxyvaleric acid-2OH,dihydrosphingosine,N-dodecoxycarbonylvaline and three unknown compounds.Additionally,the MS imaging(MSI)technique was utilized to visualize the spatial distribution of chemical constituents in raw Fuzi,revealing how different processing procedures affect the chemical variations between Heishunpian and Baifupian.The distribution patterns of different diterpenoid alkaloid subtypes partially explained the chemical differences among products.This research provides valuable insights into the material basis for future investigations of different Fuzi products. 展开更多

For a long time,the conventional superplastic forming temperature for Ti alloys is generally too high(~900-920℃),which leads to too long production cycles,heavy surface oxidation,and property reduction.In this study,an ultrafine bimodal microstructure,consisting of ultrafine equiaxed microstructure(0.66μm)and 43.3%lamellar microstructure,was achieved in the Ti-6Al-4V alloy by friction stir processing(FSP).The low-temperature superplastic behavior and deformation mechanism of the FSP Ti-6Al-4V alloy were investigated at temperatures of 550-675℃and strain rates ranging from 1×10−4to 3×10−3s−1.The FSP alloy exhibited superplastic elongations of>200%at the temperature range from 550 to 650℃,and an optimal superplastic elongation of 611%was achieved at 625℃and 1×10−4s−1.This is the first time to report the low-temperature superplasticity of the bimodal microstructure in Ti alloys.Grain boundary sliding was identified as the dominant deformation mechanism,which was effectively accommodated by the comprehensive effect of dislocation-inducedβphase precipitation and dynamic spheroidization of the lamellar structure.This study provides a novel insight into the low-temperature superplastic deformation behavior of the bimodal microstructure. 展开更多

Sequential processing(SqP)of the active layer offers independent optimization of the donor and acceptor with more targeted solvent design,which is considered the most promising strategy for achieving efficient organic solar cells(OSCs).In the SqP method,the favorable interpenetrating network seriously depends on the fine control of the bottom layer swelling.However,the choice of solvent(s)for both the donor and acceptor have been mostly based on a trial-and-error manner.A single solvent often cannot achieve sufficient yet not excessive swelling,which has long been a difficulty in the high efficient SqP OSCs.Herein,two new isomeric molecules are introduced to fine-tune the nucleation and crystallization dynamics that allows judicious control over the swelling of the bottom layer.The strong non-covalent interaction between the isomeric molecule and active materials provides an excellent driving force for optimize the swelling-process.Among them,the molecule with high dipole moment promotes earlier nucleation of the PM6 and provides extended time for crystallization during SqP,improving bulk morphology and vertical phase segregation.As a result,champion efficiencies of 17.38%and 20.00%(certified 19.70%)are achieved based on PM6/PYF-T-o(all-polymer)and PM6/BTP-eC9 devices casted by toluene solvent. 展开更多

Silicon carbide(SiC)is widely used in fields such as new energy,military radar,and aerospace due to its outstanding physical and chemical properties.The surface micro-grooves of SiC can enhance the performance of micro-electromechanical systems,micro-sensors,and field-effect transistors.However,SiC,being a brittle and hard material,poses challenges for traditional machining methods like micro-groove machining and chemical etching,including subsurface damage,short tool life,and low processing efficiency.This paper investigates the processing characteristics of femtosecond laser machining of SiC micro-grooves and compares them with those of single-crystal Si.The results indicate that femtosecond laser ablation of SiC primarily leads to melting and vaporization,forming modification,melted,and ablation areas in the affected area.Femtosecond laser processing of SiC micro-grooves involves three processes:heat absorption and melting,vaporization,and chipping,with vaporization as the primary material removal mechanism.The depth and width of SiC micro-grooves are positively correlated with pulse energy(Ep),pulse overlap rate(PO),and number of passes(Npass).The bottom roughness of the micro-grooves is positively correlated with Ep,negatively correlated with PO,and less affected by changes in the Npass.These findings further elucidate the material removal and micro-groove formation mechanisms of SiC under femtosecond laser irradiation,providing theoretical insights for high-quality and high-efficiency processing of SiC micro-grooves. 展开更多

Most of Chinese medicinal herbs are subjected to traditional processing procedures, including stir-frying, charring, steaming, boiling, and calcining before they are released into dispensaries. The marketing and identification of processed medicinal materials is a growing issue in the marketplace. However, conventional methods of identification have limitations, while DNA mini-barcoding, based on the sequencing of a short-standardized region, has received considerable attention as a new potential means to identify processed medicinal materials. In the present study, six DNA barcode loci including ITS2, psb A-trn H, rbc L, mat K, trnL(UAA) intron and its P6 loop, were employed for the authentication of 45 processed samples belonging to 15 species. We evaluated the amplification efficiency of each locus. We also examined the identification accuracy of the potential mini-barcode locus, of trnL(UAA) intron P6 loop. Our results showed that the five primary barcode loci were successfully amplified in only 8.89%——20% of the processed samples, while the amplification rates of the trnL(UAA) intron P6 loop were higher, at 75.56% successful amplification. We compared the mini-barcode sequences with Genbank using the Blast program. The analysis showed that 45.23% samples could be identified to genus level, while only one sample could be identified to the species level. We conclude that trnL(UAA) p6 loop is a candidate mini-barcode that has shown its potential and may become a universal mini-barcode as complementary barcode for authenticity testing and will play an important role in medicinal materials control. 展开更多

Nonfullerene organic solar cells(OSCs)have achieved breakthrough with pushing the efficiency exceeding 17%.While this shed light on OSC commercialization,high-performance flexible OSCs should be pursued through solution manufacturing.Herein,we report a solution-processed flexible OSC based on a transparent conducting PEDOT:PSS anode doped with trifluoromethanesulfonic acid(CF3SO3H).Through a low-concentration and low-temperature CF3SO3H doping,the conducting polymer anodes exhibited a main sheet resistance of 35Ωsq−1(minimum value:32Ωsq−1),a raised work function(≈5.0 eV),a superior wettability,and a high electrical stability.The high work function minimized the energy level mismatch among the anodes,hole-transporting layers and electron-donors of the active layers,thereby leading to an enhanced carrier extraction.The solution-processed flexible OSCs yielded a record-high efficiency of 16.41%(maximum value:16.61%).Besides,the flexible OSCs afforded the 1000 cyclic bending tests at the radius of 1.5 mm and the long-time thermal treatments at 85°C,demonstrating a high flexibility and a good thermal stability. 展开更多
