| 1 | UAV feasible path planning based on disturbed fluid and trajectory propagation显示文摘In this paper, a novel algorithm based on disturbed fluid and trajectory propagation is developed to solve the three-dimensional(3-D) path planning problem of unmanned aerial vehicle(UAV) in static environment.Firstly, inspired by the phenomenon of streamlines avoiding obstacles, the algorithm based on disturbed fluid is developed and broadened.The effect of obstacles on original fluid field is quantified by the perturbation matrix, where the tangential matrix is first introduced.By modifying the original flow field, the modified one is then obtained, where the streamlines can be regarded as planned paths.And the path proves to avoid all obstacles smoothly and swiftly, follow the shape of obstacles effectively and reach the destination eventually.Then, by considering the kinematics and dynamics equations of UAV, the method called trajectory propagation is adopted to judge the feasibility of the path.If the planned path is unfeasible, repulsive and tangential parameters in the perturbation matrix will be adjusted adaptively based on the resolved state variables of UAV.In most cases, a flyable path can be obtained eventually.Simulation results demonstrate the effectiveness of this method. | Yao Peng Wang Honglun Su Zikang | 2015 | Chinese Journal of Aeronautics2015,28,4: | 18 |
| 2 | Hot-band absorption of indocyanine green for advanced anti-stokes fluorescence bioimaging显示文摘Bright anti-Stokes fluorescence(ASF)in the first near-infrared spectral region(NIR-I,800 nm–900 nm)under the excitation of a 915 nm continuous wave(CW)laser,is observed in Indocyanine Green(ICG),a dye approved by the Food and Drug Administration for clinical use.The dependence of fluorescence intensity on excitation light power and temperature,together with fluorescence lifetime measurement,establish this ASF to be originated from absorption from a thermally excited vibrational level(hot-band absorption),as shown in our experiments,which is stronger than the upconversion fluorescence from widely-used rare-earth ion doped nanoparticles.To test the utility of this ASF NIR-I probe for advanced bioimaging,we successively apply it for biothermal sensing,cerebral blood vessel tomography and blood stream velocimetry.Moreover,in combination with L1057 nanoparticles,which absorb the ASF of ICG and emit beyond 1100 nm,these two probes generate multi-mode images in two fluorescent channels under the excitation of a single 915 nm CW laser.One channel is used to monitor two overlapping organs,urinary system&blood vessel of a live mouse,while the other shows urinary system only.Using in intraoperative real-time monitoring,such multi-mode imaging method can be beneficial for visual guiding in anatomy of the urinary system to avoid any accidental injury to the surrounding blood vessels during surgery. | Jing Zhou Xiaoxiao Fan Di Wu Jie Liu Yuhuang Zhang Zikang Ye Dingwei Xue Mubin He Liang Zhu Zhe Feng Andrey N.Kuzmin Wen Liu Paras N.Prasad Jun Qian | 2021 | Light(Science & Applications)2021,10,10: | 3 |
| 3 | Ultrathin, Lightweight, and Flexible CNT Buckypaper Enhanced Using MXenes for Electromagnetic Interference Shielding显示文摘Lightweight,flexibility,and low thickness are urgent requirements for next-generation high-performance electromagnetic interference(EMI)shielding materials for catering to the demand for smart and wearable electronic devices.Although several efforts have focused on constructing porous and flexible conductive films or aerogels,few studies have achieved a balance in terms of density,thickness,flexibility,and EMI shielding effectiveness(SE).Herein,an ultrathin,lightweight,and flexible carbon nanotube(CNT)buckypaper enhanced using MXenes(Ti3C2Tx)for high-performance EMI shielding is synthesized through a facile electrophoretic deposition process.The obtained Ti3C2Tx@CNT hybrid buckypaper exhibits an outstanding EMI SE of 60.5 dB in the X-band at 100μm.The hybrid buckypaper with an MXene content of 49.4 wt%exhibits an EMI SE of 50.4 dB in the X-band with a thickness of only 15μm,which is 105%higher than that of pristine CNT buckypaper.Furthermore,an average specific SE value of 5.7×10^(4) dB cm^(2) g^(−1) is exhibited in the 5-μm hybrid buckypaper.Thus,this assembly process proves promising for the construction of ultrathin,flexible,and high-performance EMI shielding films for application in electronic devices and wireless communications. | Rongliang Yang Xuchun Gui Li Yao Qingmei Hu Leilei Yang Hao Zhang Yongtao Yao Hui Mei Zikang Tang | 2021 | Nano-Micro Letters2021,13,4: | 2 |
| 4 | Precise genome editing without exogenous donor DNA via retron editing system in human cells显示文摘Dear Editor,CRISPR-Cas9 mediated seamless genome editing can be achieved by incorporating donor DNA into the CRISPR-Cas9 target loci via homology-directed repair(HDR),albeit with relative low efficiency due to the inefficient delivery of exogenous DNA(Cox et al.,2015;Gao,2021).Retrons are bacterial phage-defense related operons composed of a specialized reverse transcriptase(RT)and a relevant non-coding RNA(ncRNA)which can be partially reverse tran-scribed by RT initiating at a conserved guanosine(G)residue to produce a multicopy single-stranded DNA(msDNA)(Yee et al.,1984;Millman et al.,2020).After being reverse transcribed,the msDNA is usually covalently teth-ered to the ncRNA through the 2',5'-phosphodiesterbond between the priming G in ncRNA and 5'end of msDNA(Dhundale et al.,1987).The reverse transcription process,of which the specialized RT recognizes the unique secondary structure of retron ncRNA,is highly specific(Hsu et al.,1989).Additionally,desired msDNA can be generated in vivo by replacing the dispensable region of retron ncRNA with desired sequences(Mirochnitchenko et al.,1994;Simon et al.,2019).Therefore,retrons are promising biological sources for in vivo generation of DNA donors for HDR-me-diated precise genome editing. | Xiangfeng Kong Zikang Wang Renxia Zhang Xing Wang Yingsi Zhou Linyu Shi Hui Yang | 2021 | Protein & Cell2021,12,11: | 2 |
| 5 | Ultra-strong phosphorescence with 48% quantum yield from grinding treated thermal annealed carbon dots and boric acid composite显示文摘Metal-free room-temperature phosphorescence(RTP)materials are of great significance for many applications;however,they usually exhibit low efficiency and weak intensity.This article reports a new strategy for the preparation of a high-efficiency and strong RTP materials from crystalline thermal-annealed carbon dots(CDs)and boric acid(BA)composite(g-t-CD@BA)through grinding-induced amorphous to crystallization transition.Amorphous thermal-annealed CDs and BA composite(t-CD@BA)is prepared following a thermal melting and super-cooling route,where the CDs are fully dispersed in molten BA liquid and uniformly frozen in an amorphous thermal annealed BA matrix after super-cooling to room temperature.Upon grinding treatment,the fracture and fragmentation caused by grinding promote the transformation of the high-energy amorphous state to the lower energy crystalline counterparts.As a result,the CDs are uniformly in situ embedded in the BA crystal matrix.This method affords maximum uniform embedding of the CDs in the BA crystals,decreases nonradiative decay,and promotes intersystem crossing by restraining the free vibration of the CDs,thus producing strong RTP materials with the highest reported phosphorescence quantum yield(48%).Remarkably,RTP from g-t-CD@BA powder is strong enough to illuminate items with a delay time exceeding 9 s. | Qijun Li Zhenxiao Zhao Shuai Meng Yuchen Li Yunyang Zhao Bohan Zhang Zikang Tang Jing Tan Songnan Qu | 2022 | SmartMat2022,3,2: | 2 |
| 6 | Highly-efficient thermoelectric-driven light-emitting diodes based on colloidal quantum dots显示文摘Driven by sub-bandgap electric work and Peltier heat,thermoelectric-driven light-emitting diodes(TED-LEDs)not only offer much enhanced power-conversion-efficiency but also eliminate the waste heat generated during the operation of LEDs.However,costeffective and high-efficiency TED-LEDs are not readily accessible for the epitaxially grown III-V LEDs due to the high chip cost and efficiency droop at low-medium brightness(current densities).Here we show that electroluminescence of colloidal quantum dots(QDs)LEDs(QLEDs)circumvents the deficiencies faced by conventional LEDs.The optimal red-emitting device fabricated by cost-effective solution processing technics exhibits external-and internal-power-conversion-efficiency of 21.5%and 93.5%at 100 cd/m^(2),suited for high-efficiency solid-state lighting and high-resolution display.At this brightness,the electric driving voltage(V)of 1.89 V is lower than the photon voltage(Vp=hv/q=1.96 V,q being the elemental charge).With typical Vp=1.96 V,electroluminescence can be detected with the driving voltage as low as 1.0-1.2 V.Luminance of the thermoelectric-driven QLEDs(TED-QLEDs)remains ideally diffusion-dominated with the driving voltage lower than~1.5 V,and further improvement on charge transport is expected to extend the linear ideality to all practical driving voltages. | Xing Lin Xingliang Dai Zikang Ye Yufei Shu Zixuan Song Xiaogang Peng | 2022 | Nano Research2022,15,10: | 2 |
| 7 | Zeolite templated carbon nanodots for broadband ultrafast pulsed fiber laser generation显示文摘Carbon nanodots(C-dots) with a uniform size of about 2 nm are synthesized via in situ pyrolysis of n-propylamine that is confined in the nanochannels of zeolite Linde Type A(LTA). The as-synthesized C-dots@LTA composite shows nonlinear optical saturable absorption properties in a broad wavelength band and can be used as saturable absorber(SA) to generate ultrafast pulsed fiber lasers. By inserting a zeolite LTA single crystal hosting C-dots into the fiber laser cavity, mode-locked fiber lasers with long-term operation stability at 1.5 μm and 1 μm are achieved. These results show that the C-dots@LTA are a promising SA material for ultrafast pulsed fiber laser generation in a broad wavelength band. To the best of our knowledge, this is the first demonstration of a C-dots@LTA-based mode-locked fiber laser. | XINTONG XU JIAQI CHEN WENTAO SHI DALIN SUN SHAOWEN CHU LANG SUN WENFEI ZHANG YANPING CHEN JIANPANG ZHAI SHUANGCHEN RUAN ZIKANG TANG | 2019 | Photonics Research2019,7,10: | 2 |
| 8 | Synergistically boosting the elementary reactions over multiheterogeneous ordered macroporous Mo2C/NC-Ru for highly efficient alkaline hydrogen evolution显示文摘Simultaneously enhancing the reaction kinetics,mass transport,and gas release during alkaline hydrogen evolution reaction(HER)is critical to minimizing the reaction polarization resistance,but remains a big challenge.Through rational design of a hierarchical multiheterogeneous three-dimensionally(3D)ordered macroporous Mo_(2)C-embedded nitrogen-doped carbon with ultrafine Ru nanoclusters anchored on its surface(OMS Mo_(2)C/NC-Ru),we realize both electronic and morphologic engineering of the catalyst to maximize the electrocatalysis performance.The formed Ru-NC heterostructure shows regulative electronic states and optimized adsorption energy with the intermediate H*,and the Mo_(2)C-NC heterostructure accelerates the Volmer reaction due to the strong water dissociation ability as confirmed by theoretical calculations.Consequently,superior HER activity in alkaline solution with an extremely low overpotential of 15.5 mV at 10 mAcm^(−2)with the mass activity more than 17 times higher than that of the benchmark Pt/C,an ultrasmall Tafel slope of 22.7 mV dec−1,and excellent electrocatalytic durability were achieved,attributing to the enhanced mass transport and favorable gas release process endowed from the unique OMS Mo_(2)C/NC-Ru structure.By oxidizing OMS Mo_(2)C/NC-Ru into OMS MoO_(3)-RuO_(2)catalyst,it can also be applied as efficient oxygen evolution electrocatalyst,enabling the construction of a quasi-symmetric electrolyzer for overall water splitting.Such a device's performance surpassed the state-of-the-art Pt/C||RuO2 electrolyzer.This study provides instructive guidance for designing 3D-ordered macroporous multicomponent catalysts for efficient catalytic applications. | Kaixi Wang Shuo Wang Kwan San Hui Haixing Gao Duc Anh Dinh Chengzong Yuan Chenyang Zha Zongping Shao Zikang Tang Kwun Nam Hui | 2022 | Carbon Energy2022,4,5: | 2 |
| 9 | Unique sandwich design of high-efficiency heat-conducting phosphor-in-glass film for high-quality laser-driven white lighting显示文摘Multi-color phosphor-in-glass(PiG)film has been considered as a promising color converter in high-quality laser lighting owing to its outstanding merits of phosphor versatility,tunable luminescence,and simple preparation.However,the opto-thermal properties of PiG film are severely affected by the photon reabsorption and backward scattering of phosphor structure and the heat conduction of substrate.Herein,a unique sandwich design of phosphor structure was introduced in the multi-color PiG film for high-quality laser lighting.By elaborately synthesizing the borosilicate glass with low glass transition temperature(T_(g)),similar expansion coefficient,and high refractive index(RI),the sandwiched PiGs were prepared by sintering(~600℃)broadband green and red phosphor glass films on the double sides of sapphire.The green and red PiG films were tightly coated on the sapphire with no delamination and maintained higher luminescence intensity than raw phosphors at high temperatures.By simultaneously coupling photon reabsorption and backward scattering,the sandwiched green PiG film-sapphire-red PiG film(G-S-R PiG)yields a high-quality white light with a high luminous efficacy of 163 lm/W and an excellent color rendering index(CRI)of 85.4 under a laser power of 2.4 W,which are the best comprehensive results yet reported.Benefiting from the ingenious sandwich design with heat-conducting sapphire and thin PiG films,the G-S-R PiG displays low working temperatures(<200℃)under high-power laser excitation.This work reveals the role of sandwiched phosphor structure in photon loss and heat dissipation,which provides a new strategy to design PiG films for high-quality laser lighting. | Yang PENG Zikang YU Jiuzhou ZHAO Qing WANG Jiaxin LIU Bo SUN Yun MOU Mingxiang CHEN | 2022 | Journal of Advanced Ceramics2022,11,12: | 2 |

| 15 | Facile active control of a pulsed erbium-doped fiber laser using modulation depth tunable carbon nanotubes显示文摘Short pulsed fiber lasers have been widely made using single-walled carbon nanotubes as a saturable absorber(SA). However, most of the currently used devices can only operate in one determined operation state with an unchangeable modulation SA depth in the cavity, which significantly limits their application in photonic devices.In this paper, well-aligned carbon nanotube arrays are synthesized using zeolite AlPO_4-5 as a template, which features anisotropic optical absorption. The linear optical absorption of the as-synthesized carbon nanotube arrays can easily be tuned by adjusting a polarization controller, thus providing a tunable modulation depth for the carbon nanotube SA. By exploiting this SA in an erbium-doped fiber laser cavity, both Q-switched and modelocked pulsed lasers are achieved by simply adjusting a polarization controller under a fixed pump power of 330 mW. In addition, the repetition rate of the Q-switching and pulse duration of the mode-locking can be tuned according to the variation of modulation depth. Moreover, soliton molecules can be obtained when the modulation depth of the SA is 4.5%. | XINTONG XU SHUANGCHEN RUAN JIANPANG ZHAI LING LI JIHONG PEI ZIKANG TANG | 2018 | Photonics Research2018,,11: | 1 |
