| 1 | Single‑Layer ZnO Hollow Hemispheres Enable High‑Performance Self‑Powered Perovskite Photodetector for Optical Communication显示文摘The carrier transport layer with reflection reduction morphology has attracted extensive attention for improving the utilization of light.Herein,we introduced single-layer hollow ZnO hemisphere arrays(ZHAs)behaving light trapping effect as the electron transport layer in perovskite photodetectors(PDs).The singlelayer hollow ZHAs can not only reduce the reflection,but also widen the angle of the effective incident light and especially transfer the distribution of the optical field from the ZnO/FTO interface to the perovskite active layer confirmed by the 3D finitedifference time-domain simulation.These merits benefit for the generation,transport and separation of carriers,improving the light utilization efficiency.Finally,our optimized FTO/ZHA/CsPbBr3/carbon structure PDs showed high self-powered performance with a linear dynamic range of 120.3 dB,a detectivity of 4.2×10^(12) Jones,rise/fall time of 13/28μs and the f_(−3) dB of up to 28 kHz.Benefiting from the high device performance,the PD was demonstrated to the application in the directional transmission of encrypted files as the signal receiving port with super high accuracy.This work uniquely utilizes the features of high-performance self-powered perovskite PDs in optical communication,paving the path to wide applications of all-inorganic perovskite PDs. | Xiyan Pan Jianqiang Zhang Hai Zhou Ronghuan Liu Dingjun Wu Rui Wang Liangping Shen Li Tao Jun Zhang Hao Wang | 2021 | Nano-Micro Letters2021,13,4: | 3 |

| 3 | Influence of blasting load directions on tunnel stability in fractured rock mass显示文摘Tunnels in fractured rock masses are typically damaged by dynamic disturbances from various directions.To investigate the influence of blasting load directions on the stability of a tunnel with a precrack nearby,blasting tests were conducted on the physical models of an external crack around a tunnel(ECT)in this study.Failure modes of the tunnels were analysed based on stress wave theory.The Riedel-Hiermaier-Thoma(RHT)material model was employed to perform the numerical simulations on ECT models.Stress distribution around the tunnels and final failure patterns of the tunnels were characterised.The results show that,under blasting loads,the pre-crack propagates and then new cracks initiates on the incident side of the tunnel.These cracks extend towards each other and eventually coalesce.Blasting load directions significantly influence the ultimate failure mode of the tunnel in the fractured rock masses.The new cracks on the shadow side of the tunnel appear at different positions when the blasting stress waves come from various directions.The results are meaningful to the analysis of tunnel stability and optimisation of the tunnel support scheme. | Xiaohan Li Zheming Zhu Meng Wang Yun Shu Shuai Deng Dingjun Xiao | 2022 | Journal of Rock Mechanics and Geotechnical Engineering2022,14,2: | 2 |

| 6 | Does varicocele grade predict the postoperative changes of semen parameters following left inguinal micro-varicocelectomy?显示文摘Objective:To evaluate the relationship between preoperative grade and postoperative changes of semen parameters following left inguinal varicocelectomy.Methods:This study included 44 patients undergoing left microsurgical inguinal varicocelectomy.Internal spermatic veins were classified as large(4 mm or more in diameter),medium(2-4 mm),or small(2 mm or less).Changes in sperm activity,morphology and count were estimated perioperatively.The introperative findings and semen parameters were compared between varicocele groups of grades 2 and 3.Results:Both sperm motility and count improved significantly postoperatively(from(31.9±16.3)%to(47.3±15.5)%,from(28.1±28.1)106/mL to(52.1±74.2)×10^6/mL).In varicoceles with grade 2 and 3,significant differences were found in the number of large veins(0.4±0.6 vs.1.2±0.7,p<0.001)and ultrasonographic maximum diameters of spermatic vein in supine and standing positions(2.3±0.4 cm vs.2.8±0.6 cm,3.1±0.7 cm vs.3.9±0.7 cm,p=0.001 and 0.001 respectively).However no difference of changes in sperm motility and count was detected((16.3±13.5)%vs.(14.4±12.6)%,(30.5±84.4)×10^6/mL vs.(12.9±20.6)×10^6/mL respectively,p=0.65 and 0.40 respectively).Conclusion:Preoperative varicocele grade might not predict postoperative semen changes regardless of possible existence of anatomic and ultrasonographic associations. | Hongzhen Wang Xueke Wang Dingjun Fu Hua Zhu Ming-kuen Lai | 2015 | Asian Journal of Urology2015,2,3: | 1 |

| 9 | Expression and subcellular localization of cysteine- and glycine-rich protein-2 in rat undifferentiated olfactory stem cells显示文摘BACKGROUND: As a member of the LIM protein family Ⅱ, cysteine- and glycine-rich protein-2 (CRP2) has been demonstrated to play a role in the regulation of growth and differentiation of eukaryotic cells. Our previous study has demonstrated that CRP2 can be detected in the embryonic rat inner ear but not in the adult rat inner ear. However, at present, the expression of LIM protein family Ⅱ members in stem or precursor cells has not been described. OBJECTIVE: To determine the expression and sub-cellular localization of CRP2 in olfactory stem cells. DESIGN, TIME AND SETTING: An experiment with repeated measures was performed in the Laboratory of Otorhinolaryngology, Head and Neck Surgery, Xijing Hospital, the Fourth Military Medical University from February 2008 to April 2008. MATERIALS: Olfactory stem cells, and rabbit-anti-CRP2 polyclonal antibody were prepared and kept in our laboratory. METHODS: Reverse transcription polymerase chain reaction and Western blot analysis were used to detect expression of CRP2 in olfactory stem cells. Immunocytochemistry was also used to localize CRP2 in olfac- tory stem cells. MAIN OUTCOME MEASURES: The expression and sub-cellular localization of CRP2 in rat olfactory stem cells. RESULTS: CRP2 expression was found in olfactory stem cells, and CRP2 was distributed in both the nu- cleus and the cytoplasm. CONCLUSION: Confirmation of the expression and distribution of CRP2 in olfactory stem cells. | Xue Gao Zengyu Cao Jun Chen Shunli Liu Dingjun Zha Feng Wang Yang Chen Li Qiao Lianjun Lu Jianhua Qiu | 2008 | Neural Regeneration Research2008,3,5: | 0 |
| 10 | High-performance Ag_(2)BiI_(5)Pb-free perovskite photodetector显示文摘Recently,lead-free all-inorganic halide perovskites have attracted great interest because they not only have the merits of the halide perovskite family,but also are non-toxic.However,the commercialization of lead-free allinorganic perovskites is restricted by their relatively low performances,which are usually caused by the fabrication methods and undesirable interfaces between the active layer and carrier transport layers.Herein,we demonstrate a solution-processed route for high-quality Ag_(2)BiI_(5) lead-free perovskite film by adopting ideal electron transport material SnO_(2)and a carbon electrode.By optimizing the fabrication process and tailoring the composition of the perovskite active layer,a high-performance photodetector(PD)with an FTO∕SnO_(2)∕Ag_(2)BiI_(5)∕carbon structure PD is first fabricated,which shows good self-powered performance with a detectivity of as high as 5.3×10^(12)Jones and a linear dynamic range of up to 138 d B,which are better than those of the reported Pb-free perovskite PDs and comparable to high-performance Pb-based perovskite PDs.In addition,our unpackaged PDs show good light,thermal,and storage stability in air.Our results provide a special route for the development of lead-free perovskite devices in an environmentally friendly field. | ZIHAO SHUANG HAI ZHOU DINGJUN WU XUHUI ZHANG BOAO XIAO JINXIA DUAN HAO WANG | 2022 | Photonics Research2022,10,8: | 0 |
| 11 | Ultrasensitive,flexible perovskite nanowire photodetectors with long-term stability exceeding 5000 h显示文摘Photodetectors(PDs)based on perovskite nanowires are among the most promising next-generation photodetection technologies;however,their poor long-term stability is the biggest challenge limiting their commercial applica-tion.Herein,an ionic liquid,1-butyl-3 methylimidazolium tetrafuoroborate(BMIMBF_(4)),is incorporated as an additive into methylammonium lead tri-iodide(MAPbI_(3))nanowires;this not only effectively passivates defects to inhibit perovskite degradation but also leads to the formation of nanochannels,enabling fast charge transfer.As a result,the long-term stability and perfor-mance of MAPbI_(3)nanowires are considerably improved.The detectivity,linear detection range,and noise equivalent power of the MA PbI_(3)nanowire PD reach 2.06×10^(13)Jones,160dB,and 1.38×10^(-15)W Hz-^(1/2),respectively,compara-ble to the highest performance of perovskite nanowire PDs reported to date.Moreover,the unencapsulated PD can maintain 100%of its initial performance after being exposed to an open-air environment for more than 5000 h,esta-blishing it as the most stable perovskite nanowire PD reported to date.Nota-bly,the PD exhibits improved diffuse reflection imaging ability when compared with commercial silicon photodiode S2386.This study provides a new strategy for constructing sensitive,stable,and flexible perovskite PDs and will accelerate their commercial application in the future. | Dingjun Wu Yongchang Xu Hai Zhou Xin Feng Jianqiang Zhang Xiyan Pan Zheng Gao Rui Wang Guokun Ma Li Tao Hanbin Wang Jinxia Duan Houzhao Wan Jun Zhang Liangping Shen Hao Wang Tianyou Zhai | 2022 | InfoMat2022,4,9: | 0 |
| 12 | Experimental study of the effects of non-uniformly distributed fine soil on mechanical properties of Shenyang–Dandong Railway coarse-grained soil显示文摘The stress produced by repeated train loads decreases with increasing railway subgrade bed depth, and slightly weathered coarse particles of subgrade bed fillings can be broken at different levels under continuous load. Thus, the mass of fine soil, with a diameter of not more than 0.075 mm, is different at different depths. Fine soil is also sensitive to frost heave and thaw settlement. In order to study the effects of non-uniformly distributed fine soil on the mechanical properties of coarse-grained soil of the Shenyang-Dandong Railway, triaxial tests were conducted with three types of specimens, undergoing six freeze-thaw cycle numbers(0, 1, 3, 7, 9, 12) and three confining pressures(100, 200, 300 k Pa). The freezing temperature is-5 °C and the thawing temperature is +15 °C. The stress-strain behavior, static strength, resilient modulus, cohesive force and the angle of internal friction were measured for different tested specimens. As a result, the law of static strength and resilient modulus of different specimens following the increase of freeze-thaw cycles under three confining pressures is obtained. The changing law of cohesive force and friction angle of three specimens following the increase of freeze-thaw cycles is also calculated, and the different results of different specimens are also compared. | QianMi Yu JianKun Liu JingYu Liu DingJun Lv TengFei Wang | 2015 | Research in Cold and Arid Regions2015,7,5: | 0 |
