| 1 | Rocky Desertification Risk Zone Delineation in Karst Plateau Area:A Case Study in Puding County,Guizhou Province显示文摘Karst rocky desertification is a geo-ecological problem in Southwest China.The rocky desertification risk zone delineation could be used as a guide for the regional and hierarchical rocky desertification management and prevention.We chose the middle and lower reaches of the Houzhai underground basin on the karst plateau in Puding County, Guizhou Province, China as the study area and selected land use type, elevation, slope, aspect, lithology and settlement buffer as the main driving factors of the rocky desertification.The potential risk of rocky desertification was quantified with the factor-weights union method and statistical analysis method.Five grades of rocky desertification risk were delineated based on Geographic Information System.The extremely low, low, moderate, high and extremely high rocky desertification risk zones accounted for 5.01%, 44.17%, 33.92%, 15.59% and 1.30%, respectively.As a whole, the rocky desertification risk level was moderate because the area of low and moderate rocky desertification risk zones occupied 78.09% of the study area.However, more than half of the area(about 50.81%) was predicted to have moderate rocky desertification risk and above, indicating that the study area was subject to rocky desertification.Rocky desertification risk was higher in the southeast and lower in the northwest of the study area.Distinct differences in the distribution of rocky desertification risk zones corresponding to different factors have been found. | ZHANG Panpan HU Yuanman XIAO Duning LI Xiuzhen YIN Jie HE Hong S | 2010 | Chinese Geographical Science2010，20，1： | 15 |

| 3 | Virus-induced Phytoene Desaturase(PDS) Gene Silencing Using Tobacco Rattle Virus in Lilium × formolongi显示文摘Gene function analysis is challenging for Lilium due to the lack of an efficient method for stable genetic transformation. Virus-induced gene silencing(VIGS) is an attractive tool for determining gene function in plants. This study reported that Tobacco rattle virus(TRV)-based VIGS of a PHYTOENE DESATURASE(PDS) ortholog(LhPDS) can be achieved in Lilium × formolongi seedlings, with a survival rate of 92%, using the inoculation method of rubbing plus injection. Compared with untreated and mock-treated seedlings, the photobleached leaf phenotype of silenced plants significantly correlates with down-regulation of endogenous LhPDS(P ≤ 0.05). In addition, the silencing phenomenon can be observed in the growing points of plants, indicating that systemic viral infection was achieved using the protocol. The results indicate that TRV-based VIGS can be used to characterize gene function in Lilium × formolongi. This work lays the foundation for gene function analysis and molecular breeding in Lilium spp. | Hua Xu Leifeng Xu Panpan Yang Yuwei Cao Yuchao Tang Guoren He Suxia Yuan Jingyi Lei Jun Ming | 2019 | Horticultural Plant Journal2019，5，1： | 6 |

| 5 | Biodegradation of 3,5-dimethyl-2,4-dichlorophenol in saline wastewater by newly isolated Penicillium sp.yz11-22N2显示文摘In this study,the performance of 3,5-dimethyl-2,4-dichlorophenol(DCMX) degradation by a screened strain was investigated.18 S r DNA and the neighbor-joining method were used for identification of the isolated strain.The results of phylogenetic analysis and scanning electron micrographs showed that the most probable identity of the screened strain should be Penicillium sp.Growth characteristics of Penicillium sp.and degradation processes of DCMX were examined.Fourier transform infrared spectroscopy of the inoculated DCMX solution was recorded,which supported the capacity of DCMX degradation by the screened Penicillium sp.Under different salinity conditions,the highest growth rate and removal efficiency for DCMX were obtained at p H 6.0.The removal efficiency decreased from 100%to 66% when the DCMX concentration increased from 5 to 60 mg/L,respectively.Using a Box–Behnken design,the maximum DCMX removal efficiency was determined to be 98.4%.With acclimation to salinity,higher removal efficiency could be achieved.The results demonstrate that the screened Penicillium sp.has the capability for degradation of DCMX. | Zhou Yan Huijun He Chunping Yang Guangming Zeng Le Luo Panpan Jiao Huiru Li Li Lu | 2017 | Journal of Environmental Sciences2017，29，7： | 3 |
| 6 | An oncolytic adenovirus delivering TSLC1 inhibits Wnt signaling pathway and tumor growth in SMMC-7721 xenograft mice model显示文摘Tumor suppressor in lung cancer-1(TSLC1)was first identified as a tumor suppressor for lung cancer,and frequently downregulated in various types of cancers including hepatocellular carcinoma(HCC).The Wnt pathway plays a critical role in tumorigenesis,migration,and invasion in HCC.However,the function of TSLC1 in modulating Wnt signaling in HCC is unclear.In this study,we evaluated the effect of TSLC1-armed oncolytic adenovirus(S24-TSLC1)on the Wnt/β-catenin pathway,cell viability,invasion and migration abilities of HCC in vitro and the growth of SMMC-7721-xenografted tumor in mice model.We detected the expression of TSLC1 in tumor samples and HCC cell lines.The results showed that TSLC1 expression was low in HCC,but high in pericarcinomatous tissue and normal cells,which implied that TSLC1 is a tumor suppressor of liver cancer.S24-TSLC1 exhibited an antitumor effect on HCC cell growth in vitro,but did little damage to normal liver cells.Overexpression of TSLC1 downregulated the transcriptional activity of TCF4/β-catenin and inhibited the mRNA or protein expression of Wnt target genes cyclinD1 and c-myc.S24-TSLC1 also inhibited the invasion and migration of HCC cells.Animal experiments further confirmed that S24-TSLC1 significantly inhibited tumor growth of the SMMC-7721-xenografted tumor.In conclusion,TSLC1 could downregulate the Wnt signal pathway and suppress HCC cell growth,migration and invasion,suggesting that S24-TSLC1 may be a potent antitumor agent for future clinical trials in liver cancer treatment. | Yigang Wang Panpan Huang Yanping Hu Keni Guo Xiaoyuan Jia Biao Huang Xinyuan Liu Xianglei He Fang Huang | 2021 | Acta Biochimica et Biophysica Sinica2021，53，6： | 2 |
| 7 | Ultrathin FeS nanosheets with high chemodynamic activity for sensitive colorimetric detection of H_(2)O_(2) and glutathione显示文摘Iron chalcogenides have attracted great interest as potential substitutes of nature enzymes in the colorimetric biological sensing due to their unique chemodynamic characteristics.Herein,we report the preparation of ultrathin Fe S nanosheets(NSs)by a simple one-pot hydrothermal method and the prepared Fe S NSs exhibit strong Fenton-reaction activity to catalyze hydrogen peroxide(H_(2)O_(2))for generation of hydroxyl radical(^(·)OH).Based on the chromogenic reaction of resultant^(·)OH with 3,3,5,5-tetramethylbenzidine(TMB),we develop colorimetric biosensors for highly sensitive detection of H_(2)O_(2)and glutathione(GSH).The fabricated biosensors show wide linear ranges for the detection of H_(2)O_(2)(5–150μmol/L)and GSH(5–50μmol/L).Their detection limits for H_(2)O_(2)and GSH reach as low as0.19μmol/L and 0.14μmol/L,respectively.The experimental results of sensing intracellular H_(2)O_(2)and GSH demonstrate that this colorimetric method can realize the accurate detection of H_(2)O_(2)and GSH in normal cells(L02 and 3T3)and cancer cells(MCF-7 and He La).Our results have demonstrated that the synthesized Fe S NSs is a promising material to construct colorimetric biosensors for the sensitive detection of H_(2)O_(2)and GSH,holding great promising for medical diagnosis in cancer therapy. | Yefan Duan Qi Li Panpan He Yan Li Jingrun Song Jing Wang Junjie Liu Jiang Zhou Fei Chen Zhusheng Huang Jianfei Sun Ying Zhang Zhimin Luo | 2022 | Chinese Chemical Letters2022，33，6： | 2 |
| 8 | A Multi-Stage Green Barrier Strategy for the Control of Global SARS-CoV-2 Transmission via Cold Chain Goods显示文摘1.The object-to-human transmission route of SARS-CoV-2 At the time of writing,coronavirus disease 2019(COVID-19),which is caused by the severe acute respiratory syndrome coron-avirus 2(SARS-CoV-2),has been a global pandemic for more than a year.As of 22 September 2021,the global cumulative incidence exceeds 229 million cases,and the number of deaths has exceeded 4.75 million[1].The current situation of epidemic prevention and control within the countries around the world can be roughly divided into two stages:the pandemic stage that the United States,the United Kingdom,and India are still experiencing(as of 23 September 2021,newly reported cases in the last 24 h in the United States,United Kingdom,and India are 202840,31095,and 26964,respectively[1]);and the normalized epidemic pre-vention and control stage that countries such as China and New Zealand are currently in. | Xu He Xinwang Liu Pan Li Panpan Wang Haijun Cheng Wenqian Li Boda Li Ting Liu Jun Ma | 2022 | Engineering2022，8，2： | 2 |

| 10 | Advances in swept-source optical coherence tomography and optical coherence tomography angiography显示文摘Background:The fast development of swept-source optical coherence tomography(SS-OCT)and swept-source optical coherence tomography angiography(SS-OCTA)enables both anterior and posterior imaging of the eye.These techniques have evolved from a research tool to an essential clinical imaging modality.Main text:The longer wavelength and faster speed of SS-OCT and SS-OCTA facilitate better visualization of structure and vasculature below pigmented tissue with a larger field of view of the posterior segment and 360-degree visualization of the anterior segment.In the past 10 years,algorithms dealing with OCT and OCTA data also vastly improved the image quality and enabled the automated quantification of OCT-and OCTA-derived metrics.This technology has enriched our current understanding of healthy and diseased eyes.Even though the high cost of the systems currently limited the widespread use of SS-OCT and SS-OCTA at the first beginning,the gap between research and clinic practice got obviously shortened in the past few years.Conclusions:SS-OCT and SS-OCTA will continue to evolve rapidly,contributing to a paradigm shift toward more widespread adoption of new imaging technology in clinical practice. | Fang Zheng Xiaofeng Deng Qi Zhang Jingliang He Panpan Ye Shan Liu Peng Li Jian Zhou Xiaoyun Fang | 2023 | Advances in Ophthalmology Practice and Research2023，3，2： | 1 |
| 11 | Design and experiment of seed furrow cleaning device based on throwing and sliding for no-till maize seeding显示文摘In order to solve the serious problems of seeds are covered by residual film and overhead by straw during no-till seeding,a seed furrow cleaning device for no-till maize seeding was developed,which adopted a collaborative cleaning method of rotating spring teeth and curved sliding shovel.The movement process and motion trajectory of throwing residual film and straw were constructed.The maximum distance of throwing to one side in horizontal and maximum height in vertical were obtained.The motion trajectory of adjacent spring teeth was analyzed by Matlab,the motion trajectories of adjacent spring teeth at different speeds of 120 r/min,150 r/min and 180 r/min were achieved,the theoretical analysis results showed that the area of omitted area decreased with the increase of rotation speed.Based on theoretical and simulation analysis of critical parameters,the forward speed of machine,rotation speed of spring teeth,and dip angle between spring teeth and rotary disc were selected as the influencing factor.Straw cleaning rate(SCR)and residual film cleaning rate(RFCR)were selected as the response values for three factors and three levels of orthogonal experiment design.The optimal combination of the selected parameters was obtained,and the field test verification was also conducted.The results showed that the rotation speed of spring teeth,forward speed and dip angle of spring teeth significantly affect SCR and RFCR were in decreasing order.The field test results indicated that when forward speed was 6 km/h,rotation speed of spring teeth was 180 r/min and dip angle of spring teeth was 40°,SCR and RFCR were 88.27%and 84.31%,respectively.This study provides a reference for the development of no-till seeder in Xinjiang and the northwestern regions of China. | Panpan Yuan Hongwen Li Caiyun Lu Qingjie Wang Jin He Shenghai Huang Dandan Cui | 2022 | International Journal of Agricultural and Biological Engineering2022，15，4： | 1 |
| 12 | Development of a double antibodies sandwich ELISA for the detection of avian leukosis virus subgroup J based on monoclonal antibodies against gp85显示文摘Avian leukosis virus(ALV)belongs to the genus Alpharetrovirus of the family Retroviridae and can cause various types of neoplastic diseases,even mortality in infected chickens[1].ALV is categorized into seven subgroups,including A,B,C,D,E,J,and K,based on the pathogenicity and antibody neutralization characteristics[2].The subgroup E is endogenous and transmitted by Mendelian inheritance.The subgroups A,B,C,D,J,and K are exogenous and oncogenic,transmitted horizontally and vertically and caused different pathological lesions[3].Among them,subgroups A and B were most common in commercial poultry and subgroup J is the major cause for myeloid leukosis and nephromas in broilers.In 1980,ALV subgroup J(ALV-J)was first isolated and identified from infected broilers in Britain.It caused significant economic losses in the poultry industry because of increased myelocytomas and other tumors[4].In China,ALV-J was first detected in broilers in 1999 and,subsequently,spread to other chicken types.Compared to other ALV subgroups,ALV-J has been a serious issue in China poultry industry since 2007.Currently,there is no effective vaccine and drugs against ALV-J infection;thus,early detection and elimination of ALV-positive breeder chickens are key measures to block vertical and horizontal ALV-J transmission.Given the importance of ALV to the poultry industry,many ALV detection methods,including virus isolation,immunofluorescence assays,neutralization tests,reverse transcription polymerase chain reaction(PCR)or real-time fluorescent quantitative PCR-based molecular diagnosis ways,and enzyme-linked immunosorbent assays(ELISA)have been developed.Among them,ELISA is widely used for its efficiency,convenience,and sensitivity.Yun et al.[5]developed an antigen-capture ELISA for the detection of ALV based on highly conserved antigen p27.Yu et al.[6]exploited a colloidal gold test strip specific for the detection of ALV p27 antigen.These antigen capture-based serological detection methods share obviously simple,accurate,and rapid advantages in comparison with conventional time-consuming methods of indirect immunofluorescence assay or neutralization tests.However,it is difficult to identify different subgroups of ALV using p27-coated antibodies. | Lili Cao Panpan Zhao He Ding Nan Wang Xue Zhang Shuxian Yuan Hang Dong Yanbing Guo Xinhua Yao Qinlei Yu Hongze Shao Pengtao Gong | 2021 | Acta Biochimica et Biophysica Sinica2021，53，10： | 1 |
| 13 | Self-Floating Efficient Solar Steam Generators Constructed Using Super-Hydrophilic N,O Dual-Doped Carbon Foams from Waste Polyester显示文摘Solar evaporation is recognized as a prospective technique to produce freshwater from non-drinkable water using inexhaustible solar energy.However,it remains a challenge to fabricate low-cost solar evaporators with obviously reduced water evaporation enthalpy to achieve high evaporation rates.Herein,N,O dual-doped carbon foam(NCF)is fabricated from the lowtemperature carbonization of poly(ethylene terephthalate)(PET)waste by melamine/molten salts at 340℃.During carbonization,melamine reacts with carboxylic acids of PET degradation products to yield a crosslinking network,and then molten salts catalyze the decarboxylation and dehydration to construct a stable framework.Owing to rich N,O-containing groups,3D interconnected pores,super-hydrophilicity,and ultra-low thermal conductivity(0.0599 W m^(−1) K^(−1)),NCF not only achieves high light absorbance(ca.99%)and solar-to-thermal conversion,but also promotes the formation of water cluster to reduce water evaporation enthalpy by ca.37%.Consequently,NCF exhibits a high evaporation rate(2.4 kg m^(−2) h^(−1)),surpassing the-state-of-the-art solar evaporators,and presents good antiacid/basic abilities,long-term salt-resistance,and self-cleaning ability.Importantly,a large-scale NCF-based outdoor solar desalination device is developed to produce freshwater.The daily freshwater production amount per unit area(6.3 kg)meets the two adults’daily water consumption.The trash-to-treasure strategy will give impetus to the development of low-cost,advanced solar evaporators from waste plastics for addressing the global freshwater shortage. | Huiying Bai Ning Liu Liang Hao Panpan He Changde Ma Ran Niu Jiang Gong Tao Tang | 2022 | Energy & Environmental Materials2022，5，4： | 1 |
| 14 | Efficient removal of naphthalene-2-ol from aqueous solutions by solvent extraction显示文摘Naphthalene-2-ol is a typical biologically recalcitrant pollutant in dye wastewater.Solvent extraction of naphthalene-2-ol from aqueous solutions using mixed solvents was investigated.Various extractants and diluents were evaluated,and the effects of volume ratio of extractant to diluent,initial p H,initial concentration of naphthalene-2-ol in aqueous solution,extraction time,temperature,volume ratio of organic phase to aqueous phase(O/A),stirring rate and extraction stages,on extraction efficiency were examined separately.Regeneration and reuse of the spent extractant were also investigated.Results showed that tributyl phosphate(TBP) achieved 98% extraction efficiency for naphthalene-2-ol in a single stage extraction,the highest among the 12 extractants evaluated.Extraction efficiency was optimized when cyclohexane and n-octane were used as diluents.The solvent combination of 20% TBP,20% n-octanol and 60% cyclohexane(V/V) obtained the maximum extraction efficiency for naphthalene-2-ol,99.3%,within 20 min using three cross-current extraction stages under the following extraction conditions:O/A ratio of 1:1,initial p H of 3,25°C and stirring rate of 150 r/min.Recovery of mixed solvents was achieved by using 15%(W/W) Na OH solution at an O:A ratio of 1:1 and a contact time of 15 min.The mixed solvents achieved an extraction capacity for naphthalene-2-ol stably higher than90% during five cycles after regeneration. | Jingjing Shao | 2016 | Journal of Environmental Sciences2016，28，9： | 1 |
| 15 | Fish-Eye Image Distortion Correction Based on Adaptive Partition Fitting显示文摘The acquisition of images with a fish-eye lens can cause serious image distortion because of the short focal length of the lens.As a result,it is difficult to use the obtained image information.To make use of the effective information in the image,these distorted imagesmust first be corrected into the perspective of projection images in accordance with the human eye’s observation abilities.To solve this problem,this study presents an adaptive classification fitting method for fish-eye image correction.The degree of distortion in the image is represented by the difference value of the distances fromthe distorted point and undistorted point to the center of the image.The target points selected in the image are classified by the difference value.In the areas classified by different distortion differences,different parameter curves were used for fitting and correction.The algorithm was verified through experiments.The results showed that this method has a substantial correction effect on fish-eye images taken by different fish-eye lenses. | Yibin He Wenhao Xiong Hanxin Chen Yuchen Chen Qiaosen Dai Panpan Tuand Gaorui Hu | 2021 | Computer Modeling in Engineering & Sciences2021，，1： | 1 |

| 17 | Molecular engineering tuning optoelectronic properties of thieno[3,2-b]thiophenes-based electrochromic polymers显示文摘Thieno[3,2-b]thiophene(TT)monomers end-capped with 3,4-ethylenedioxythiophene(EDOT)moieties are electropolymerized to formπ-conjugated polymers with distinct electrochromic(EC)properties.Steric and electronic factors(electron donor and acceptor substituents)in the side groups of the TT core,as well as the structure of the polymer backbone strongly affect the electrochemical and optical properties of the polymers and their electrochromic characteristics.The studied polymers show low oxidation potentials,tunable from-0.78 to+0.30 V(vs.Fc/Fc^+)and the band gaps from 1.46 to 1.92 eV and demonstrate wide variety of color palettes in polymer films in different states,finely tunable by structural variations in the polymer backbone and the side chains.EC materials of different colors in their doped/dedoped states have been developed(violet,deep blue,light blue,green,brown,purple-red,pinkish-red,orange-red,light gray,cyan and colorless transparent).High optical contrast(up to 79%),short response time(0.57-0.80 s),good cycling stability(up to 91%at 2000 cycles)and high coloration efficiency(up to 234.6 cm2C^(-1))have been demonstrated and the influence of different factors on the above parameters of EC polymers have been discussed. | Mengmeng Zhu Weishuo Li Panpan Xu Jingjing Shi Shan Shao Xiaosi Zhu Yitong Guo Yaowu He Zhao Hu Hongtao Yu Yanan Zhu Igor F.Perepichka Hong Meng | 2017 | Science China Chemistry2017，60，1： | 0 |
| 18 | The SUPER reporting guideline suggested for reporting of surgical technique显示文摘Background:Existing reporting guidelines pay insufficient attention to the detail and comprehensiveness reporting of surgical technique.The Surgical techniqUe rePorting chEcklist and standaRds(SUPER)aims to address this gap by defining reporting standards for surgical technique.The SUPER guideline intends to apply to articles that encompass surgical technique in any study design,surgical discipline,and stage of surgical innovation.Methods:Following the EQUATOR(Enhancing the QUAlity and Transparency Of health Research)Network approach,16 surgeons,journal editors,and methodologists reviewed existing reporting guidelines relating to surgical technique,reviewed papers from 15 top journals,and brainstormed to draft initial items for the SUPER.The initial items were revised through a three-round Delphi survey from 21 multidisciplinary Delphi panel experts from 13 countries and regions.The final SUPER items were formed after an online consensus meeting to resolve disagreements and a three-round wording refinement by all 16 SUPER working group members and five SUPER consultants.Results:The SUPER reporting guideline includes 22 items that are considered essential for good and informative surgical technique reporting.The items are divided into six sections:background,rationale,and objectives(items 1 to 5);preoperative preparations and requirements(items 6 to 9);surgical technique details(items 10 to 15);postoperative considerations and tasks(items 16 to 19);summary and prospect(items 20 and 21);and other information(item 22).Conclusions:The SUPER reporting guideline has the potential to guide detailed,comprehensive,and transparent surgical technique reporting for surgeons.It may also assist journal editors,peer reviewers,systematic reviewers,and guideline developers in the evaluation of surgical technique papers and help practitioners to better understand and reproduce surgical technique. | Kaiping Zhang Yanfang Ma Jinlin Wu Qianling Shi Leandro Cardoso Barchi Marco Scarci Rene Horsleben Petersen Calvin S.H.Ng Steven Hochwald Ryuichi Waseda Fabio Davoli Robert Fruscio Giovanni Battista Levi Sandri Michel Gonzalez Benjamin Wei Guillaume Piessen Jianfei Shen Xianzhuo Zhang Panpan Jiao Yulong He Nuria M.Novoa Benedetta Bedetti Sebastien Gilbert Alan D.L.Sihoe Alper Toker Alfonso Fiorelli Marcelo F.Jimenez Toni Lerut Aung Y.Oo Grace S.Li Xueqin Tang Yawen Lu Hussein Elkhayat Tomaz Stupnik Tanel Laisaar Firas Abu Akar Diego Gonzalez-Rivas Zhanhao Su Bin Qiu Stephen D.Wang Yaolong Chen Shugeng Gao | 2023 | Hepatobiliary Surgery and Nutrition2023，12，4： | 0 |
| 19 | Structural self-reconstruction strategy empowering Ni-rich layered cathodes with low-strain for superior cyclabilities显示文摘The key to hindering the commercial application of Ni-rich layered cathode is its severe structural and interface degradation during the undesired phase transition(hexagonal to hexagonal(H2→H3)),degenerating from the build-up of mechanical strain and undesired parasitic reactions.Herein,a perovskite Li_(0.35)La_(0.55)TiO_(3)(LLTO)layer is built onto Ni-rich cathodes crystal to induce layered@spinel@perovskite heterostructure to solve the root cause of capacity fade.Intensive exploration based on structure characterizations,in situ X-ray diffraction techniques,and first-principles calculations demonstrate that such a unique heterostructure not only can improve the ability of the host structure to withstand the mechanical strain but also provides fast diffusion channels for lithium ions as well as provides a protective barrier against electrolyte corrosion.Impressively,the LLTO modified LiNi_(0.9)Co_(0.05)Mn_(0.05)O_(2)cathode manifests an unexpected cyclability with an extremely high-capacity retention of≈94.6%after 100 cycles,which is superior to the pristine LiNi_(0.9)Co_(0.05)Mn_(0.05)O_(2)(79.8%).Furthermore,this modified electrode also shows significantly enhanced cycling stability even withstanding a high cut-off voltage of 4.6 V.This surface self-reconstruction strategy provides deep insight into the structure/interface engineering to synergistically stabilize structure stability and regulate the physicochemical properties of Ni-rich cathodes,which will also unlock a new perspective of surface interface engineering for layered cathode materials. | Zhouliang Tan Yunjiao Li Xiaoming Xi Shijie Jiang Xiaohui Li Xingjie Shen Panpan Zhang Zhenjiang He | 2023 | Nano Research2023，16，4： | 0 |
| 20 | An efficient method to engage oxide ceramics in low-temperature interfacial reactions: Microstructure evolution and kinetics behaviors based on supercooling in a transient liquid phase bonding joint显示文摘Ductile transient liquid phase(TLP)bonding joints reinforced by multiple precipitates were produced using novel pre-sintered coatings and Au-Si fillers;therefore,the highest strength of NiTi/sapphire joints brazed at 460℃ for 30 min reached 72 MPa.The pre-sintering process improved the surface-active of sapphire by forming metastable Ti_(3)O and non-stoichiometric Al_(2)O_(3).The typical brazing seam consisted of O-rich compounds,TiSi_(2),and Ti-Ni-Si,wherein the O-rich phase featured different crystallinity depending on the oxygen content.The sapphire/seam interface was either a nanoscale diffusion region or a Si-rich amorphous layer.The breakdown of the Stokes-Einstein relation(SER)occurred,and the deviation from SER increased with a higher cooling rate.The influence of coating thickness was reflected in(i)the supercooling related to the viscosity and fractional exponent of liquids and(ii)the microstructural change of the joint related to the driving force for crystal growth.This work presented a new strategy for joining ceramics to metals at lower temperatures but using the joint at higher temperatures;furthermore,gave an insight into the microstructure evolution and kinetics behaviors based on supercooling in a transient liquid phase bonding joint. | Jia Yang Wanqi Zhao Panpan Lin Qiuguang Zhang Xinfei Zhang Tiesong Lin Peng He Yanli Zhuang | 2023 | Journal of Materials Science & Technology2023，，20： | 0 |
