| 1 | Research progress in ZnO single-crystal:growth, scientific understanding, and device applications显示文摘Zinc oxide,a wide band-gap semiconductor,has shown extensive potential applications in high-efficiency semiconductor photoelectronic devices,semiconductor photocatalysis,and diluted magnetic semiconductors.Due to the undisputed lattice integrity,ZnO single crystals are essential for the fabrication of high-quality ZnO-based photoelectronic devices,and also believed to be ideal research subjects for understanding the underlying mechanisms of semiconductor photocatalysis and diluted magnetic semiconductors.This review,which is organized in two main parts,introduces the recent progress in growth,basic characterization,and device development of ZnO single crystals,and some related works in our group.The first part begins from the growth of ZnO single crystal,and summarizes the fundamental and applied investigations based on ZnO single crystals.These works are composed of the fabrication of homoepitaxial ZnO-based photoelectronic devices,the research on the photocatalysis mechanism,and dilute magnetic mechanism.The second part describes the fabrication of highly thermostable n-type ZnO with high mobility and high electron concentration through intentional doping.More importantly,in this part,a conceptual approach for fabricating highly thermostable p-type ZnO materials with high mobility through an integrated three-step treatment is proposed on the basis of the preliminary research. | Feng Huang Zhang Lin Wenwen Lin Jiye Zhang Kai Ding Yonghao Wang Qinghong Zheng Zhibing Zhan Fengbo Yan Dagui Chen Peiwen Lv Xian Wang | 2014 | Chinese Science Bulletin2014，59，12： | 11 |
| 2 | Enhancing the strain hardening and ductility of Mg-Y alloy by introducing stacking faults显示文摘Due to the insufficient slip systems,Mg and its alloys exhibit poor ductility during plastic deformation at room temperature.To solve this problem,alloying is considered as a most effective method to improve the ductility of Mg alloys,which attracts wide attentions of industries.However,it is still a challenge to understand the ductilization mechanism,because of the complicated alloying elements and their interactions with Mg matrix.In this work,pure Mg and Mg-Y alloys were comparatively studied to investigate the effect of Y addition on microstructure evolution and mechanical properties.A huge increase of uniform elongation,from 5.3%to 20.7%,was achieved via only 3 wt%addition of yttrium.TEM results revealed that the only activated slip system in pure Mg was basalslip,led to its poor ductility at room temperature.In contrast,a large number of stacking faults and non-basal dislocations withcomponent were observed in the deformed Mg-Y alloy,which was proposed as the main reason for significant improvement of strain hardening and ductility.High resolution TEM indicated that most of the stacking faults were II and 12 intrinsic faults,which played a critical role in improving the ductility of Mg-Y alloy.Addition of Y into Mg alloy decreased the stacking fault energy,which induced high density stacking faults in the grain interior. | Kang Wei Lirong Xiao Bo Gao Lei Li Yi Liu Zhigang Ding Wei Liu Hao Zhou Yonghao Zhao | 2020 | Journal of Magnesium and Alloys2020，8，4： | 8 |
| 3 | Facile Synthesis of FePS3 Nanosheets@MXene Composite as a High-Performance Anode Material for Sodium Storage显示文摘Searching for advanced anode materials with excellent electrochemical properties in sodium-ion battery is essential and imperative for next-generation energy storage system to solve the energy shortage problem.In this work,two-dimensional(2D)ultrathin FePS3 nanosheets,a typical ternary metal phosphosulfide,are first prepared by ultrasonic exfoliation.The novel 2D/2D heterojunction of FePS3 nanosheets@MXene composite is then successfully synthesized by in situ mixing ultrathin MXene nanosheets with FePS3 nanosheets.The resultant FePS3 nanosheets@MXene hybrids can increase the electronic conductivity and specific surface area,assuring excellent surface and interfacial charge transfer abilities.Furthermore,the unique heterojunction endows FePS3 nanosheets@MXene composite to promote the diffusion of Na^+ and alleviate the drastic change in volume in the cyclic process,enhancing the sodium storage capability.Consequently,the few-layered FePS3 nanosheets uniformly coated by ultrathin MXene provide an exceptional reversible capacity of 676.1 mAh g^−1 at the current of 100 mA g^−1 after 90 cycles,which is equivalent to around 90.6% of the second-cycle capacity(746.4 mAh g^−1).This work provides an original protocol for constructing 2D/2D material and demonstrates the FePS3@MXene composite as a potential anode material with excellent property for sodium-ion batteries. | Yonghao Ding Yu Chen Na Xu Xintong Lian Linlin Li Yuxiang Hu Shengjie Peng | 2020 | Nano-Micro Letters2020，12，4： | 2 |
| 4 | Folic acid supplement rescues ethanol-induced developmental defects in the zebrafish embryos显示文摘Fetal alcohol syndrome(FASD)describes a range of birth defects.Mechanisms of FASD-associated defects are not well understood.It has great significance to investigate whether nutrient sup-plements like folic acid(FA)can effectively rescue etha nol-induced defects.Moreover,it is very important to determine the optimal time for FA supplementation when it can most effectively antagonize the teratogenic effects of ethanol during embryonic development.Our results indicated that ethanol exposure interrupted the development of zebrafish embryos and induced multiple defects in cardiac function,pharyngeal arch arteries,vessel,craniofacial cartilage,pharyngeal arches,brain,somite and hemoglobin formation.The expressions of critical genes that play important roles in above organs such as tbx1,flk-1,|hand2,ngn1,huc,titin,gata-1 and c-myb were reduced,and the apoptosis was increased in ethanol-treated group.FA supplementation could reverse ethanol-induced defects,improve the decreased expressions of above genes and reduce the apoptosis.We also found that giving FA at 6-12 h post-fertilization(hpf),which is at the gastrula period(5.25--10 hpf),can obviously prevent the teratogenicity of ethanol.This research provides clues for elucidating the mechanism of fetal abnormalties caused by alcohol intake and for preventing FASD. | Qiu Jiang Ding Lu Feng Wang Yawen Zhang Li Cao Yonghao Gui Shuna Sun | 2020 | Acta Biochimica et Biophysica Sinica2020，52，5： | 1 |
| 5 | NIR-responsive Collagen-based Sponge Coated with Polydimethylsiloxane/Candle Soot for Oil-Water Separation显示文摘To fabricate an oil-water separation material that is rich in source,eco-friendly,and responsive,in this study,we successfully developed a collagen-based sponge for application to oil-water separation based on a green and facile strategy.In this design,widely-available collagen(COL)was used as the substrate:it was immersed in polydimethylsiloxane(PDMS)suspension with candle soot(CS)nanoparticles,followed by hot curing.The resultant sponge(CS/PDMS-COL)possessed good hydrophobicity with a water contact angle of 148.3°under a low PDMS concentration of 2%.The results from field emission scanning electron microscope,Fourier transform infrared spectrometer,X-ray photoelectron spectrometer,and X-ray diffractometry demonstrated the successful coating of CS and PDMS on the surface of COL substrate.The CS/PDMS-COL can adsorb eight oils,with the adsorption capacity for trichloromethane reaching 95 g/g.With benzene as the target adsorbent,the separation efficiency was maintained at no less than 95%even after recycling 20 times.CS/PDMS-COL was also used to separate oil-in-water emulsion.Moreover,the sponge killed bacteria effectively due to its excellent near-infrared photothermal responsiveness.This study provides new insight into the preparation of facile oil-water separation materials based on naturally occurring biomaterials effortlessly. | Min Zhang Chenchen Guo Yu Wang Yunlong Zhang Hui Wu Liulian Huang Yonghao Ni Cuicui Ding Lihui Chen | 2022 | Paper And Biomaterials2022，7，3： | 0 |

| 7 | Predicting single-phase solid solutions in as-sputtered high entropy alloys:High-throughput screening with machine-learning model显示文摘Searching for single-phase solid solutions(SPSSs)in high-entropy alloys(HEAs)is a prerequisite for the intentional design and manipulation of microstructures of alloys in vast composition space.However,to date,reported SPSS HEAs are still rare due to the lack of reliable guiding principles for the synthesis of new SPSS HEAs.Here,we demonstrate an ensemble machine-learning method capable of discovering SPSS HEAs by directly predicting quinary phase diagrams based only on atomic composition.A total of 2198 experimental structure data are extracted from as-sputtered quinary HEAs in the literature and used to train a random forest classifier(termed AS-RF)utilizing bagging,achieving a prediction accuracy of 94.6%compared with experimental results.The AS-RF model is then utilized to predict 224 quinary phase diagrams including∼32,000 SPSS HEAs in Cr-Co-Fe-Ni-Mn-Cu-Al composition space.The extrapolation capability of the AS-RF model is then validated by performing first-principle calculations using density functional theory as a benchmark for the predicted phase transition of newly predicted HEAs.Finally,interpretation of the AS-RF model weighting of the input parameters also sheds light on the driving forces behind HEA formation in sputtered systems with the main contributors being:valance electron concentration,work function,atomic radius difference and elementary symmetries. | Ji-Chang Ren Junjun Zhou Christopher J.Butch Zhigang Ding Shuang Li Yonghao Zhao Wei Liu | 2023 | Journal of Materials Science & Technology2023，，7： | 0 |

| 9 | Excellent strength-ductility combination of Cr_(26)Mn_(20)Fe_(20)Co20Ni_(14) high-entropy alloy at cryogenic temperatures显示文摘In the present study,a face-centered cubic non-equiatomic Cr_(26)Mn_(20)Fe_(20)Co20Ni_(14) high-entropy alloy(HEA)with a low stacking fault energy of 17.6 mJ m^(−2) was prepared by vacuum induction melting,forging and annealing processes.The recrystallized sample is revealed to exhibit an excellent combination of strength and ductility over a wide temperature range of 4.2–293 K.With decreasing temperature from 293 to 77 K,the ductility and ultimate tensile strength(UTS)gradually increase by 30% to 95% and 137% to 1020 MPa,respectively.At the lowest temperature of 4.2 K,the ductility keeps 65% and the UTS increases by 200% to 1300 MPa,which exceed those published in the literature,including conventional 300 series stainless steels.Detailed microstructural analyses of this alloy reveal a change of deformation mechanisms from dislocation slip and nano-twinning at 293 K to nano-phase transformation at 4.2 K.The cooperation and competition of multiple nano-twinning and nano-phase transformation are responsible for the superior tensile properties at cryogenic temperatures.Our study provides experimental evidence for potential cryogenic applications of HEAs. | Xuzhou Gao Wei Jiang Yiping Lu Zhigang Ding Jizi Liu Wei Liu Gang Sha Tongming Wang Tingju Li Isaac T.H.Chang Yonghao Zhao | 2023 | Journal of Materials Science & Technology2023，，23： | 0 |
