1Microstructure and Properties of ZL101 Alloy Affected by Substrate Movement Speed of a Novel Semisolid Continuous Micro Fused-Casting for Metal Process显示文摘A novel semisolid continuous Micro Fused-Casting additive manufacturing technology for producing a ZL101 alloy strip was developed, Micro Fused-Casting means that the semisolid metal slurry was pressed out from the outlet of bottom of crucible to the movable plate. The degree of sub-cooling was easily provided by movement of substrate in the micro fused-casting area. Under the aid of 3 D manufacturing software, the ZL101 alloy strip was solidified and formed layer by layer. The microstructure and properties of ZL101 semisolid slurry were improved by the cooling conditions. The results showed that the ZL101 alloy strip samples fabricated by Micro Fused-Casting had uniform structures and good performances with the substrate movement speed at 20 mm/s and the temperature at 590 ℃, the ultimate tensile strength and elongation of the ZL101 alloy strip reached 242.59 MPa and 7.71%, while the average Vickers hardness was 82.55 HV.罗晓强 韩永军 LI Qingbin HU Xiaoming XUE Lingwei 2018Journal of Wuhan University of Technology(Materials Science)2018,33,3:6
2High-performance polymer solar cells with efficiency over 18%enabled by asymmetric side chain engineering of non-fullerene acceptors显示文摘Side-chain engineering has been considered as one of the most promising strategies to optimize non-fullerene small-molecule acceptors(NFSMAs).Previous efforts were focused on the optimization of alkyl-chain length,shape,and branching sites.In this work,we propose that asymmetric side-chain engineering can effectively tune the properties of NFSMAs and improve the power conversion efficiency(PCE)for binary non-fullerene polymer solar cells(NFPSCs).Specifically,by introducing asymmetric side chains into the central core,both of the absorption spectra and molecule orientation of NFSMAs are efficiently tuned.When blended with polymer donor PM6,NFPSCs with EH-HD-4F(2-ethylhexyl and 2-hexyldecyl side chains)demonstrate a champion PCE of 18.38%with a short-circuit current density(J_(SC))of 27.48 mA cm^(-2),an open circuit voltage(V_(OC))of 0.84 V,and a fill factor(FF)of 0.79.Further studies manifest that the proper asymmetric side chains in NFSMAs could induce more favorable face-on molecule orientation,enhance carrier mobilities,balance charge transport,and reduce recombination losses.Shihao Chen Lingwei Feng Tao Jia Jianhua Jing Zhicheng Hu Kai Zhang Fei Huang 2021Science China Chemistry2021,64,7:4
3Outstanding Humidity Chemiresistors Based on Imine-Linked Covalent Organic Framework Films for Human Respiration Monitoring显示文摘Human metabolite moisture detection is important in health monitoring and non-invasive diagnosis.However,ultra-sensitive quantitative extraction of respiration information in real-time remains a great challenge.Herein,chemiresistors based on imine-linked covalent organic framework(COF)films with dual-active sites are fabricated to address this issue,which demonstrates an amplified humidity-sensing signal performance.By regulation of monomers and functional groups,these COF films can be pre-engineered to achieve high response,wide detection range,fast response,and recovery time.Under the condition of relative humidity ranging from 13 to 98%,the COFTAPB-DHTA film-based humidity sensor exhibits outstanding humidity sensing perfor-mance with an expanded response value of 390 times.Furthermore,the response values of the COF film-based sensor are highly linear to the relative humidity in the range below 60%,reflecting a quantitative sensing mechanism at the molecular level.Based on the dual-site adsorption of the(-C=N-)and(C-N)stretching vibrations,the revers-ible tautomerism induced by hydrogen bonding with water molecules is demonstrated to be the main intrinsic mechanism for this effective humidity detection.In addition,the synthesized COF films can be further exploited to effectively detect human nasal and oral breathing as well as fabric permeability,which will inspire novel designs for effective humidity-detection devices.Xiyu Chen Lingwei Kong Jaafar Abdul-Aziz Mehrez Chao Fan Wenjing Quan Yongwei Zhang Min Zeng Jianhua Yang Nantao Hu Yanjie Su Hao Wei Zhi Yang 2023Nano-Micro Letters2023,15,9:2
4Erianin suppresses constitutive activation of MAPK signaling pathway by inhibition of CRAF and MEK1/2显示文摘Constitutive activation of RAS-RAF-MEK-ERK signaling pathway(MAPK pathway)frequently occurs in many cancers harboring RAS or RAF oncogenic mutations.Because of the paradoxical activation induced by a single use of BRAF or MEK inhibitors,dual-target RAF and MEK treatment is thought to be a promising strategy.In this work,we evaluated erianin is a novel inhibitor of CRAF and MEK1/2 kinases,thus suppressing constitutive activation of the MAPK signaling pathway induced by BRAF V600E or RAS mutations.KinaseProfiler enzyme profiling,surface plasmon resonance(SPR),isothermal titration calorimetry(ITC),cellular thermal shift assay,computational docking,and molecular dynamics simulations were utilized to screen and identify erianin binding to CRAF and MEK1/2.Kinase assay,luminescent ADP detection assay,and enzyme kinetics assay were investigated to identify the efficiency of erianin in CRAF and MEK1/2 kinase activity.Notably,erianin suppressed BRAF V600E or RAS mutant melanoma and colorectal cancer cell by inhibiting MEK1/2 and CRAF but not BRAF kinase activity.Moreover,erianin attenuated melanoma and colorectal cancer in vivo.Overall,we provide a promising leading compound for BRAF V600E or RAS mutant melanoma and colorectal cancer through dual targeting of CRAF and MEK1/2.Penglei Wang Xuechao Jia Bingbing Lu Han Huang Jialin Liu Xuejiao Liu Qiong Wu Yamei Hu Pan Li Huifang Wei Tingting Liu Dengyun Zhao Lingwei Zhang Xueli Tian Yanan Jiang Yan Qiao Wenna Nie Xinli Ma Ruihua Bai Cong Peng Zigang Dong Kangdong Liu 2023Signal Transduction and Targeted Therapy2023,8,4:1

6The Development Model and Countermeasures of China's Next Generation AI Industry显示文摘In the new round of IT revolution, the AI industry has become a new engine driving economic growth. In such a context, major developed countries actively prepare and plan for this industry, and China also attaches great importance to next-generation AI development. At present, the China's nextgeneration AI industry has distinctive shortcomings in the development of core chips, basic algorithms and corresponding talents. China should make full use of its enormous advantages and favorable conditions in technology and sensibly choose from a development model of business innovation, fast iteration, application layer driving base layer, and self-developed technology standards. By drawing on the experience of developed countries, China can accelerate its building and improvement of government supported mechanisms, upgrade its system of venture capital and services, enhance the advancement of basic research in chips and algorithms, and invest more in the cultivation and introduction of next-generation AI talents in a bid to quickly strengthen the core competitiveness of the China's next-generation AI industry.Du Chuanzhong Hu Jun Chen Weixuan Wu Lingwei 2019Contemporary Social Sciences2019,4,2:0
7A Miracle of Human Development in China(1950-2030)显示文摘China has created an even more spectacular miracle in human development than in economic growth.From 1950 to 2015,China went through three stages of socio-economic development; the 'extremely poor era',the 'era of letting some people get rich first' and the 'era of common prosperity',raising its human development to an increasingly higher level.With the world's fastestgrowing Human Development Index(HDI) during this period,China evolved from a very 'low human development level' to a 'high human development level'.And it is expected to enter a new stage with a 'very high human development level' around 2021.This human development miracle in China indicates that socialism with Chinese characteristics gains strength from being a major country and a late mover,as well as from its development path and socialist system.China,arguably contributing the most to the entirety of human development,can serve as a role model for developing countries and can lead the path for the all-round development of billions of people.Hu An’gang Wang Hongchuan Xu Qingtong(译) Wu Lingwei(译) 2018Contemporary Social Sciences2018,3,3:0
8Unlocking the charge doping effect in softly intercalated ultrathin ferromagnetic superlattice显示文摘The electrolyte-assisted exfoliation strategy is widely employed to synthesize ultrathin two-dimensional(2D)materials.Yet,spins in 2D magnets are susceptible to the electrolyte due to the underlying charge doping effect.Hence,it is crucial to understand and trace the doping process during the delamination of 2D magnets.Taking the prototype Fe_(3)GeTe_(2),we utilized soft organic cations to exfoliate the bulk and obtain a freestanding organ-ic–inorganic hybrid superlattice with a giant electron doping effect as high as 6.9×10^(14)/cm^(2)(~1.15 electrons per formula unit).A remarkable ferromagnetic transition exceeding 385 K was revealed in these superlattices,together with unique anisotropic saturation magnetization.The doping enhanced the in-plane electron–phonon coupling and thus optimized originally poor indirect double-exchange scenario for spin electrons.The emerging vertical magnetization shift phenomenon served to evaluate the uniformity of charge doping.The above findings provide a new perspective for understanding the role of parasitic charge in 2D magnetism.Liang Hu Bingzhang Yang Zhipeng Hou Yangfan Lu Weitao Su Lingwei Li 2023eScience2023,3,3:0
9Introduction of nanotwins into nanoprecipitations strengthened CoCrNiMo_(0.2) alloy to achieve strength and ductility trade-off:A comparative research显示文摘Normal strengthening methods through precipitations and deformation obviously enhance the strength of metallic materials while resulting in the sacrifice of ductility,and synergistic improvement of strength and ductility is currently an urgent requirement.Herein we developed a cryogenic deformation combined with an annealing method to fabricate CoCrNiMo_(0.2) medium entropy alloy,which achieved an ultrahigh strength of 1.8 GPa with synergistic improvement in strength and ductility.Microstructure,mechanical performance,and strengthening mechanisms of the developed alloys were investigated compared with that prepared by the regular room temperature deformation method.It was found that high-density nanotwins were produced in CoCrNiMo_(0.2) MEA via cryogenic deformation.Fine grains,hard precipitations,and high volume fraction of nanotwins greatly strengthened the alloy,obtaining a yield and ultimate tensile strength of 1400 MPa and 1800 MPa.Ductility improvement of the developed alloy was mainly attributed to the production of deformation nanotwins due to the lower stacking fault energy,which greatly increases the dislocation storage ability,and thus,the ductility of the alloy was enhanced.Hao Zhang Ziyi Ren Yonggang Tong Yongle Hu Xixi Ji Lingwei Yang Kaiming Wang Jingzhong Fang Hui Chen Xiubing Liang 2023Journal of Materials Science & Technology2023,,25:0
