| 2 | Single-End Adaptive Optics Compensation for Emulated Turbulence in a Bi-Directional 10-Mbit/s per Channel Free-Space Quantum Communication Link Using Orbital-Angular-Momentum Encoding显示文摘A single-end adaptive-optics(AO)module is experimentally demonstrated to mitigate the emulated atmospheric turbulence efects in a bi-directional quantum communication link,which employs orbital angular momentum(OAM)for data encoding.A classical Gaussian beam is used as a probe to detect the turbulence-induced wavefront distortion in the forward direction of the link.Based on the detected wavefront distortion,an AO system located on one end of the link is used to simultaneously compensate for the forward and backward channels.Specifcally,with emulated turbulence and when the probe is turned on,the mode purity of photons carrying OAMℓ=1 is improved by∼21%with AO mitigation.We also measured the performance when encoding data using OAM{ℓ=−1,+2}and{ℓ=−2,+1}in the forward and backward channels,respectively,at 10 Mbit/s per channel with one photon per pulse on average.For this case,we found that the AO system could reduce the turbulence efects increased quantum-symbolerror-rate(QSER)by∼76%and∼74%,for both channels in the uni-directional and bi-directional cases,respectively.Similar QSER improvement is observed for the opposite direction channels in the bi-directional case. | Cong Liu Kai Pang Zhe Zhao Peicheng Liao Runzhou Zhang Haoqian Song Yinwen Cao Jing Du Long Li Hao Song Yongxiong Ren Guodong Xie Yifan Zhao Jiapeng Zhao Seyed M.H.Rafsanjani Ari N.Willner Jeffrey H.Shapiro Robert W.Boyd Moshe Tur Alan E.Willner | 2019 | Research2019，，1： | 3 |
| 3 | Simultaneously improving mechanical properties and corrosion resistance of as-cast AZ91 Mg alloy by ultrasonic surface rolling显示文摘Mg alloy casting parts commonly suffer from drawbacks of low surface properties,high susceptibility to corrosion,unsatisfactory absolute strength,and poor ductility,which seriously limit their wide application.Here,a surface nanocrystallization technique,i.e.,ultrasonic surface rolling(USR),was applied on an as-cast AZ91 Mg alloy sheet to improve its corrosion resistance and mechanical properties.The USR produces double smooth surfaces with Ra 0.036μm and gradient nanostructured surface layers on the sheet.Due to this special microstructure modification,the USR sheet exhibits 55%and 50%improvements in yield strength and ultimate tensile strength without visibly sacrificed ductility comparable to its untreated counterpart,as well as a 24%improvement in surface hardness.The USR sheet also shows good corrosion resistance in 3.5wt%NaCl aqueous solution.The corrosion current density of the USR sheet reduces by 63%after immersion for 1 h,and 25%after immersion for 24 h compared to that of the untreated counterpart.The enhanced strength and hardness are mainly related to the gradient nanostructure.The improved corrosion resistance is mainly ascribed to the decreased surface roughness,nanostructured surface,and residual compressive stress.The present results state that USR is an effective and attractive method to improve the multiple properties of Mg alloy cast-ing parts,and thus can be used as an additional and last working procedure to achieve high-performance Mg alloy casting parts. | Jing Han Cong Wang Yuanming Song Zhiyuan Liu Jiapeng Sun Jiyun Zhao | 2022 | International Journal of Minerals,Metallurgy and Materials2022，29，8： | 1 |
| 4 | The genomic characteristics and pathogenicity of a mammalian orthoreovirus within a new lineage from wild pika in plateau显示文摘Emerging and re-emerging viruses from wild animals have seriously threatened the health of humans and domesticated animals in recent years.Herein,we isolated a new mammalian orthoreovirus(MRV),Pika/MRV/GCCDC7/2019(PMRV-GCCDC7),in the Qinghai-Tibet Plateau wild pika(Ochotona curzoniae).Though the PMRVGCCDC7 shows features of a typical reovirus with ten gene segments arranged in 3:3:4 in length,the virus belongs to an independent evolutionary branch compared to other MRVs based on phylogenetic tree analysis.The results of cellular susceptibility,species tropism,and replication kinetics of PMRV-GCCDC7 indicated the virus could infect four human cell lines(A549,Huh7,HCT,and LoVo)and six non-human cell lines,including Vero-E6,LLCMK2,BHK-21,N2a,MDCK,and RfKT cell,derived from diverse mammals,i.e.monkey,mice,canine and bat,which revealed the potential of PMRV-GCCDC7 to infect a variety of hosts.Infection of BALB/c mice with PMRVGCCDC7 via intranasal inoculation led to relative weight loss,lung tissue damage and inflammation with the increase of virus titer,but no serious respiratory symptoms and death occurred.The characterization of the new reovirus from a plateau-based wild animal has expanded our knowledge of the host range of MRV and provided insight into its risk of trans-species transmission and zoonotic diseases. | Kexin Zong Yuanyuan Guo Jingdong Song Maoshun Liu Junfeng Hao Jie Zhang Xin Li Shiyan Zhu Shuting Huo Ziqian Xu Peipei Liu Yingze Zhao Yuhai Bi Jiapeng Qu George F.Gao Jun Liu | 2023 | Virologica Sinica2023，38，6： | 0 |
| 5 | Optimization of process parameters for preparation of powdered activated coke to achieve maximum SO_(2)adsorption using response surface methodology显示文摘Powdered activated coke(PAC)is a good adsorbent of SO_(2),but its adsorption capacity is affected by many factors in the preparation process.To prepare the PAC with a high SO_(2)adsorption capacity using JJ-coal under flue gas atmosphere,six parameters(oxygen-coal equivalent ratio,reaction temperature,reaction time,O_(2)concentration,CO_(2)concentration,and H_(2)O concentration)were screened and optimized using the response surface methodology(RSM).The results of factor screening experiment show that reaction temperature,O_(2)concentration,and H_(2)O(g)concentration are the significant factors.Then,a quadratic polynomial regression model between the significant factors and SO_(2)adsorption capacity was established using the central composite design(CCD).The model optimization results indicate that when reaction temperature is 904.74℃,O_(2)concentration is 4.67%,H_(2)O concentration is 27.98%,the PAC(PAC-OP)prepared had a higher SO_(2)adsorption capacity of 68.15 mg/g while its SO_(2)adsorption capacity from a validation experiment is 68.82 mg/g,and the error with the optimal value is 0.98%.Compared to two typical commercial activated cokes(ACs),PAC-OP has relatively more developed pore structures,and its SBET and Vtot are 349 m^(2)/g and 0.1475 cm3/g,significantly higher than the 186 m^(2)/g and 0.1041 cm3/g of AC1,and the 132 m^(2)/g and 0.0768 cm3/g of AC2.Besides,it also has abundant oxygen-containing functional groups,its surface O content being 12.09%,higher than the 10.42%of AC1 and 10.49%of AC2.Inevitably,the SO_(2)adsorption capacity of PAC-OP is also significantly higher than that of both AC1 and AC2,which is 68.82 mg/g versus 32.53 mg/g and 24.79 mg/g,respectively. | Binxuan ZHOU Tao WANG Tianming XU Cheng LI Yuan ZHAO Jiapeng FU Zhen ZHANG Zhanlong SONG Chunyuan MA | 2021 | Frontiers in Energy2021，15，1： | 0 |
| 6 | Carbon-covered Tungsten Carbide Nanoparticles: Solid-state Synthesis and Application as Stable Electrocatalysts for the Hydrogen Evolution Reaction显示文摘Carbon-covered tungsten carbide nanoparticles(cc-WCNPs) were prepared via a one-step solid-statereaction between W(CO)6 and triphenylamine at 850 ℃ tinder a sealed Ar atmosphere. As novel electrocatalysts forthe hydrogen evolution reaction(HER), cc-WCNPs exhibit an onset potential of-0.14 V vs. reversible hydrogenelectrode(RHE) and a Tafel slope of 64.6 mV/dec in a 0.5mol/L H2SO4 solution. Additionally, these cc-WCNPscatalysts also show excellent electrocatalytic stability after 1000 cycles. | ZHANG Xuena ZHONG Xinwen YANG Zhe SONG Jiapeng LU Haiyan | 2016 | Chemical Research in Chinese Universities2016，32，6： | 0 |
| 7 | Achieving gradient heterogeneous structure in Mg alloy for excellent strength-ductility synergy显示文摘Most metals including Mg alloys have a longstanding dilemma of strength-ductility trade-off,which is hindering their wider applications.In this study,we propose a gradient heterogeneous grain(GHG)structure for evading this trade-off dilemma and ultrasonic severe surface rolling is attempted to construct this novel structure in ZE41 Mg alloy.Here,the GHG structure combine the benefits of gradient structure and heterogeneous grain structure and introduce large microstructural heterogeneities.Compared to the coarse-grain and heterogeneous-grain structured alloys,the GHG structured one exhibits dramatical enhancement in strength,ductility,and strain hardening capability.To the best of our knowledge,its strength becomes much higher than that of common ZE41 Mg alloys at no reduction in ductility.These unique mechanical properties stem from not only the individual contribution of the heterogeneous structure components including the fine/ultrafine grains and deformed coarse grains but also their synergistic effect via hetero-deformation induced strengthening and hardening effects.In summary,our study provides a feasible way to develop new Mg alloys with high strength and good ductility. | Jing Han Jiapeng Sun Yuanming Song Bingqian Xu Zhenquan Yang Songsong Xu Ying Han Guosong Wu Jiyun Zhao | 2023 | Journal of Magnesium and Alloys2023，11，7： | 0 |
| 8 | Highly interconnected macroporous MBG/PLGA scaffolds with enhanced mechanical and biological properties via green foaming strategy显示文摘In this study,mesoporous bioactive glass particles(MBGs) are incorporated into poly(lactic-co-glycolic acid)(PLGA) to fabricate highly interconnected macroporous composite scaffolds with enhanced mechanical and biological properties via a developed supercritical carbon dioxide(scCO_(2)) foaming method Scaffolds show favorable highly interconnected and macroporous structure through a high foaming pressure and long venting time foaming strategy.Specifically,scaffolds with porosity from 73% to 85%,pore size from 120 μm to 320 μm and interconnectivity of over 95% are controllably fabricated at MBG content from 0 wt% to 20 wt%.In comparison with neat PLGA scaffolds,composite scaffolds perform improved strength(up to 1.5 folds) and Young's modulus(up to 3 folds).The interconnected macroporous structure is beneficial to the ingrowth of cells.More importantly,composite scaffolds also provide a more promising microenvironment for cellular proliferation and adhesion with the release of bioactive ions.Hopefully,MBG/PLGA scaffolds developed by the green foaming strategy in this work show promising morphological,mechanical and biological features for tissue regeneration. | Chaobo Song Jiapeng Zhang Shuang Li Shengbin Yang Eryi Lu Zhenhao Xi Lian Cen Ling Zhao Weikang Yuan | 2021 | Chinese Journal of Chemical Engineering2021，34，1： | 0 |
