| 1 | Poly(dimethyl siloxane)anti-corrosion coating with wide pH-responsive and self-healing performance based on core-shell nanofiber containers显示文摘In this research,core-shell electrospun fibers loaded with the shell of cellulose acetate and the core of oleic acid and alkyd varnish resin were synthesized and used within poly(dimethyl siloxane)(PDMS)to prepare self-healing and p H-responsive coatings for a steel substrate.The morphology of the electrospun fibers was characterized by scanning electron microscopy,transmission electron microscopy and confocal fluorescence microscopy.Thermo gravimetric analysis and Fourier transform infrared spectroscopy revealed that the self-healing agents were loaded successfully with a loading rate of 2.9%.The properties of the fiber-PDMS composite coating were characterized by water contact angle measurements,mechanical tests,electrochemical impedance spectroscopy,and scanning Kelvin probe.Results show that the maximum self-healing efficiencies of the fiber-PDMS coating in alkaline and acidic solution are 95.96%and 97.04%,respectively.The composition of the self-healing agents at the damaged part of the coating was verified by an infrared mapping test and using an energy dispersive spectrometer.In addition,the sandpaper abrasion test shows the hydrophobic effect of fiber-PDMS coating remains above 88.2%and decreases slightly through the addition of abrasion cycles.This research can pave the way for the industrial applications of p H-responsive self-healing coatings. | Xiaohong Ji Wei Wang Xia Zhao Lifei Wang Fubin Ma Yanli Wang Jizhou Duan Baorong Hou | 2022 | Journal of Materials Science & Technology2022，，6： | 4 |
| 2 | Integrated prodrug micelles with two-photon bioimaging and pH-triggered drug delivery for cancer theranostics显示文摘Nanodrug carriers with fluorescence radiation are widely used in cancer diagnosis and therapy due to their real-time imaging,less side effect,better drug utilization as well as the good bioimaging ability.However,traditional nanocarriers still suffer from unexpectable drug leakage,unsatisfactory tumor-targeted drug delivery and shallow imaging depth,which limit their further application in cancer theranostics.In this study,an integrated nanoplatform is constructed by polymeric prodrug micelles with two-photon and aggregation-induced emission bioimaging,charge reversal and drug delivery triggered by acidic pH.The prodrug micelles can be self-assembled by the TPPEI(DA/DOX)-PEG prodrug polymer,which consists of the two-photon fluorophore(TP),dimethylmaleic anhydride(DA)grafted polyethyleneimine(PEI)and polyethylene glycol(PEG).The PEG segment,DOX and DA are bridged to polymer by acid cleavable bonds,which provides the micelles a‘stealth’property and a satisfactory stability during blood circulation,while the outside PEG segment is abandoned along with the DA protection in the tumor acidic microenvironment,thus leading to charge reversal-mediated accelerated endocytosis and tumor-targeted drug delivery.The great antitumor efficacy and reduced side effect of these pH-sensitive prodrug micelles are confirmed by antitumor assays in vitro and in vivo.Meanwhile,these micelles exhibited great deep-tissue two-photon bioimaging ability up to 150 lm in depth.The great antitumor efficacy,reduced side effect and deep two-photon tissue imaging make the TP-PEI(DA/DOX)-PEG prodrug micelles would be an efficient strategy for theranostic nanoplatform in cancer treatment. | Hong Xu Boxuan Ma Jizhou Jiang Sutong Xiao Rongrong Peng Weihua Zhuang Gaocan Li Yunbing Wang | 2020 | Regenerative Biomaterials2020，7，2： | 1 |

| 6 | Laser intensity induced transparency in atom-molecular transition process显示文摘We propose a new transparency mechanism,which is based on photoassociation(PA)laser intensity induced transitional frequency shift for ultracold cesium molecules formed in PA scheme.The PA laser intensity is supposed to change before the atom-molecule resonance.Thus,a remarkable transparent effect for PA laser is expected to appear in the vicinity of original resonant transitional line,where the variation of PA laser intensity induces the shift of the excited molecular levels.The mechanism is different from electromagnetically induced transparency effect and interesting for further research on the scattering length for cesium atomic condensate. | Jie Ma Yuqing Li Jizhou Wu Liantuan Xiao Suotang Jia | 2014 | Chinese Science Bulletin2014，59，22： | 1 |

| 8 | Self-adjustable hyper-graphs for video pose estimation based on spatial-temporal subspace construction显示文摘Dear editor,In recent years many supervised video pose estimation methods have achieved growing successes based on well-labeled training datasets. Nonetheless, when facing roughly-labeled training data, it still remains challenging to intrinsically encode the video contents’ spatial-temporal coherency for robust video pose estimation.Some researches aimed to directly improve and refine the existing confidence maps by combining the spatial-temporal structure models [1, 2].

| 12 | Effective Slowing and Trapping of Cs Atoms in an Ultrahigh-Vacuum Apparatus显示文摘We report the effective slowing and trapping of Cs atoms in an ultrahigh-vacuum apparatus.The heated Cs atoms in an oven are slowed using a Zeeman slower after the oven chamber and then trapped using a magneto-optical trap in a science chamber.Compared to the traditional vacuum pressure of~10^(−7)Pa determined by the vapor pressure of Cs atoms in the oven chamber,the designed cold nipple and differential pumping tube are used between the oven and the oven chamber to achieve a lower vacuum pressure of~3.6×10^(−9)Pa.This is beneficial for achieving and maintaining an ultrahigh vacuum in the science chamber.We demonstrate the performance of our apparatus through the effective slowing of Cs atoms and an optimal magneto-optical trap. | Li Yuqing Du Huiying Wang Yunfei Wu Jizhou Liu Wenliang Li Peng Fu Yongming Ma Jie Xiao Liantuan Jia Suotang | 2023 | 激光与光电子学进展2023，60，17： | 0 |
| 13 | Wide and fast-frequency tuning for a stabilized diode laser显示文摘External-cavity diode laser(ECDL)has important applications in many fundamental and applied researches.Here we report a method to fast and widely tune the frequency of a stabilized ECDL.The beat frequency between the ECDL and a frequency-locked reference laser is identified by the voltagecontrolled oscillator contained in a phase detector,whose output voltage is subtracted from the flexibly controlled PC signal to generate an error signal for stabilizing the ECDL.The output frequency of the stabilized ECDL can be shifted at a short characteristic time of∼150µs within a range of∼620 MHz.The wide and fast-frequency tuning achieved by our method is compared with other previous works.We demonstrated the performance of our method by the efficient sub-Doppler cooling of Cs atoms with the temperature as low as 6µK. | Yunfei Wang Yuqing Li Jizhou Wu Wenliang Liu Peng Li Yongming Fu Jie Ma Liantuan Xiao Suotang Jia | 2022 | Frontiers of physics2022，17，2： | 0 |
| 14 | Generation of coherent blue light via bichromatic pumping in cesium vapor显示文摘Diode-pumped alkali lasers,possessing high efficiency and narrow linewidth,can provide feasible solutions for wavelength ranges difficult to reach by commercial lasers.In this study,we investigate a generation of coherent blue light(CBL)via four-wave mixing(FWM)-based up-conversion processes in cesium(Cs)vapor.A bichromatic pumping scheme with 852-and 917-nm lasers drives the Cs atoms to the 6D5/2 excited level,followed by cascaded decay of 6D5/2→7 P3/2→6 S1/2,producing 456-nm CBL under phase matching conditions.The fluorescence in multiple bands from blue to near-and far-infrared in the FWM process is demonstrated under different experimental conditions.To optimize the experimental parameters,we investigate the dependence of 456-nm CBL on the vapor temperature,frequency,and intensity of the two pump lasers.A maximum power of 2.94 mW is achieved with pump powers of 430 mW(for 852 nm)and 470 mW(for 917 nm).The corresponding conversion efficiency is 1.5%/W,three-fold higher than those in previous studies.Our results can contribute to fundamental research on atom–photon interactions and quantum metrology. | Guiyuan Ge Li Tian Guoqing Zhang Ningxuan Zheng Wenliang Liu Vladimir Sovkov Jizhou Wu Yuqing Li Yongming Fu Peng Li Jie Ma Liantuan Xiao Suotang Jia | 2023 | Frontiers of physics2023，18，4： | 0 |
| 15 | Atom-optically synthetic gauge fields for a noninteracting Bose gas显示文摘Synthetic gauge fields in synthetic dimensions are now of great interest.This concept provides a convenient manner for exploring topological phases of matter.Here,we report on the first experimental realization of an atom-optically synthetic gauge field based on the synthetic momentum-state lattice of a Bose gas of ^(133)Cs atoms,where magnetically controlled Feshbach resonance is used to tune the interacting lattice into noninteracting regime.Specifically,we engineer a noninteracting one-dimensional lattice into a two-leg ladder with tunable synthetic gauge fields.We observe the flux-dependent populations of atoms and measure the gauge field-induced chiral currents in the two legs.We also show that an inhomogeneous gauge field could control the atomic transport in the ladder.Our results lay the groundwork for using a clean noninteracting synthetic momentum-state lattice to study the gauge field-induced topological physics. | Yuqing Li Jiahui Zhang Yunfei Wang Huiying Du Jizhou Wu Wenliang Liu Feng Mei Jie Ma Liantuan Xiao Suotang Jia | 2022 | Light(Science & Applications)2022，11，3： | 0 |

| 17 | Optimization of integrated geological-engineering design of volume fracturing with fan-shaped well pattern显示文摘According to the variable toe-to-heel well spacing, combined with the dislocation theory, discrete lattice method, and finite-element-method(FEM) based fluid-solid coupling, an integrated geological-engineering method of volume fracturing for fan-shaped well pattern is proposed considering the geomechanical modeling, induced stress calculation, hydraulic fracturing simulation, and post-frac productivity evaluation. Besides, we propose the differential fracturing design for the conventional productivity-area and the potential production area for fan-shaped horizontal wells. After the fracturing of the conventional production area for H1 fan-shaped well platform, the research shows that the maximum reduction of the horizontal principal stress difference in the potential productivity-area is 0.2 MPa, which cannot cause the stress reversal, but this reduction is still conducive to the lateral propagation of hydraulic fractures. According to the optimized fracturing design, in zone-Ⅰ of the potential production area, only Well 2 is fractured, with a cluster spacing of 30 m and an injection rate of 12 m^(3)/min per stage;in zone-Ⅱ, Well 2 is fractured before Well 3, with a cluster spacing of 30 m and an injection rate of 12 m^(3)/min per stage. The swept area of the pore pressure drop in the potential production area is small, showing that the reservoir is not well developed. The hydraulic fracturing in the toe area can be improved by, for example, properly densifying the fractures and adjusting the fracture distribution, in order to enhance the swept volume and increase the reservoir utilization. | TANG Jizhou WANG Xiaohua DU Xianfei MA Bing ZHANG Fengshou | 2023 | Petroleum Exploration and Development2023，50，4： | 0 |
