| 1 | Highly efficient solution-processed CZTSSe solar cells based on a convenient sodium-incorporated post-treatment method显示文摘In CZTSSe solar cells,a simple sodium-incorporation post-treatment method toward solution-processed Cu2Zn Sn S4precursor films is presented in this work.An ultrathin NaCl film is deposited on Cu2Zn Sn S4precursor films by spin-coating NaCl solution.In subsequent selenization process,the introduction of Na Cl is found to be benefacial for the formation of Cu2-xSe,which can further facilitate the element transportation,leading to dense and smooth CZTSSe films with large grains and less impurity Cu2Sn(S,Se)3phase.SIMS depth profiles confirm the gradient distribution of the sodium element in Na-doped absorbers.Photoluminescence spectra show that the introduction of appropriate sodium into the absorber can inhibit the band tail states.As high as 11.18% of power conversion efficiency(PCE)is achieved for the device treated with 5 mg mL^-1 NaCl solution,and an average efficiency of Na-doped devices is 10.71%,13%higher than that of the control groups(9.45%).Besides,the depletion width and the charge recombination lifetime can also have regular variation with sodium treatment.This work offers an easy modification method for high-quality Na-doped CZTSSe films and high-performance devices,in the meantime,it can also help to further understand the effects of sodium in CZTSSe solar cells. | Biwen Duan Linbao Guo Qing Yu Jiangjian Shi Huijue Wu Yanhong Luo Dongmei Li Sixin Wu Zhi Zheng Qingbo Meng | 2020 | Journal of Energy Chemistry2020，29，1： | 8 |
| 2 | Surface defect ordered Cu_(2)ZnSn(S,Se)_(4) solar cells with efficiency over 12% via manipulating local substitution显示文摘The environmentally friendly Cu_(2)ZnSn(S,Se)_(4)(CZTSSe) compounds are promising direct bandgap materials for application in thin film solar cells, but the spontaneous surface defects disordering would lead to large open-circuit voltage deficit(V_(oc,deficit)) and significantly limit kesterite photovoltaics performance,primarily arising from the generated more recombination centers and insufficient p to n conversion at p-n junction. Herein, we establish a surface defects ordering structure in CZTSSe system via local substitution of Cu by Ag to suppress disordered Cu_(Zn) defects and generate benign n-type Zn_(Ag) donors. Taking advantage of the decreased annealing temperature of Ag F post deposition treatment(PDT), the high concentration of Ag incorporated into surface absorber facilitates the formation of surface ordered defect environment similar to that of efficient CIGS PV. The manipulation of highly doped surface structure could effectively reduce recombination centers, increase depletion region width and enlarge the band bending near p-n junction. As a result, the Ag F-PDT device finally achieves maximum efficiency of 12.34% with enhanced V_(oc) of 0.496 V. These results offer a new solution route in surface defects and energy-level engineering, and open the way to build up high quality p-n junction for future development of kesterite technology. | Changcheng Cui Dongxing Kou Wenhui Zhou Zhengji Zhou Shengjie Yuan Yafang Qi Zhi Zheng Sixin Wu | 2022 | Journal of Energy Chemistry2022，31，4： | 4 |
| 3 | Adjusting the SnZn defects in Cu_(2)ZnSn(S,Se)_(4) absorber layer via Ge^(4+) implanting for efficient kesterite solar cells显示文摘The development of kesterite photovoltaic solar cells has been hindered by large open-circuit voltage(V_(oc))deficit.Recently,Snzn deep point defect and associative defect cluster have been recognized as the main culprit for the Voc losses.Therefore,manipulating the deep-level donor of Snzn antisite defects is crucial for breaking through the bottleneck of present Cu_(2) ZnSn(S,Se)_(4)(CZTSSe)photovoltaic technology.In this study,the Snzn deep traps in CZTSSe absorber layer are suppressed by incorporation of Ge.The energy levels and concentration of Snzn defects measured by deep-level transient spectroscopy(DLTS)decrease significantly.In addition,the grain growth of CZTSSe films is also promoted due to Ge implantation,yielding the high quality absorber layer.Consequently,the efficiency of CZTSSe solar cells increases from 9.15%to 11.48%,largely attributed to the 41 mV Voc increment. | Yueqing Deng Zhengji Zhou Xin Zhang Lei Cao Wenhui Zhou Dongxing Kou Yafang Qi Shengjie Yuan Zhi Zheng Sixin Wu | 2021 | Journal of Energy Chemistry2021，30，10： | 4 |
| 4 | Study of seismic behavior of PHC piles with partial normal-strength deformed bars显示文摘Nine PHC piles with partial normal-strength deformed bars were prepared in present study,and cyclic loading tests were implemented to evaluate these piles’seismic performance.The influence of the axial compression ratio and the amount of normal-strength deformed bars on failure modes,crack patterns,strength,stiffness,and ductility were examined.The test findings indicate that the change of axial compression ratio has a noticeable influence on the failure mode of PHC piles.A larger axial compression ratio results in a higher cracking bending resistance,ultimate bending resistance,and initial stiffness,but the propagation heights of flexural cracks decrease as the axial compression ratio increases.Furthermore,increasing the amount of normal-strength deformed bars causes a slight decrease in ductility.Finally,a calculation formula was proposed to predict the flexural capacity of PHC piles with partial normal-strength deformed bars. | Zhang Xizhi Zhang Shaohua Xu Shengbo Niu Sixin | 2020 | Earthquake Engineering and Engineering Vibration2020，19，2： | 3 |
| 5 | Long noncoding RNA(lncRNA)HOTAIR:Pathogenic roles and therapeutic opportunities in gastric cancer显示文摘Gastric cancer is one of the first malignant cancers in the world and a large number of people die every year due to this disease.Many genetic and epigenetic risk factors have been identified that play a major role in gastric cancer.HOTAIR is an effective epigenetic agent known as long noncoding RNA(lncRNA).HOTAIR has been described to have biological functions in biochemical and cellular processes through interactions with many factors,leading to genomic stability,proliferation,survival,invasion,migration,metastasis,and drug resistance.In the present article,we reviewed the prognostic value of the molecular mechanisms underlying the HOTAIR regulation and its function in the development of Gastric Cancer,whereas elucidation of HOTAIR–protein and HOTAIR–DNA interactions can be helpful in the identification of cancer processes,leading to the development of potential therapeutic strategies. | Wencheng Kong Guang Yin Sixin Zheng Xinchun Liu Akao Zhu Panpan Yu Jian Zhang Yuqiang Shan Rongchao Ying Huicheng Jin | 2022 | Genes & Diseases2022，9，5： | 3 |
| 6 | Lithium-assisted synergistic engineering of charge transport both in GBs and GI for Ag-substituted Cu2ZnSn(S,Se)4 solar cells显示文摘Although silver(Ag) substitution offers several benefits in eliminating bulk defects and facilitating interface type inversion for Cu2ZnSn(S,Se)4(CZTSSe) photovoltaic(PV) technology, its further development is still hindered by the fairly low electrical conductivity due to the significant decrease of acceptors amount.In this work, a versatile Li–Ag co-doping strategy is demonstrated to mitigate the poor electrical conductivity arising from Ag through direct incorporating Li via postdeposition treatment(PDT) on top of the Ag-substituted CZTSSe absorber. Depth characterizations demonstrate that Li incorporation increases ptype carrier concentration, improves the carrier collection within the bulk, reduces the defects energy level as well as inverts the electric field polarity at grain boundaries(GBs) for Ag-substituted CZTSSe system. Benefiting from this lithium-assisted complex engineering of electrical performance both in grain interior(GI) and GBs, the power conversion efficiency(PCE) is finally increased from 9.21% to 10.29%. This systematic study represents an effective way to overcome the challenges encountered in Ag substitution,and these findings support a new aspect that the synergistic effects of double cation dopant will further pave the way for the development of high efficiency kesterite PV technology. | Xiangyun Zhao Xiaohuan Chang Dongxing Kou Wenhui Zhou Zhengji Zhou Qingwen Tian Shengjie Yuan Yafang Qi Sixin Wu | 2020 | Journal of Energy Chemistry2020，29，11： | 2 |
| 7 | Production and Characterisation of Monoclonal Antibodies against 19-Nortestosterone显示文摘Objective To produce anti‐19‐Nortestosterone (NT) monoclonal antibodies and identify their immunological characteristics. Methods Hybridomas were prepared by fusing NS0 mouse myeloma cells with splenocytes isolated from immunized BALB/c mice. Noncompetitive and competitive indirect ELISA were employed to screen positive cell clones. A caprylic acid ammonium sulphate (CAAP) method was used to purify NT mAb, and the Batty saturation method was used to determine the affinity constant (Kaff). Results Five hybridoma cell lines, named NT‐1, NT‐2, NT‐3, NT‐4, and NT‐5, were identified and their corresponding mAbs were of the IgG 1 isotype with a k light chain. The Kaffs of all mAbs were between 2.6 and 4.7×10 9 L/mol. The titers and IC 50 values of purified ascite fluids were in the range of (0.64-2.56)×10 5 and (0.55-1.0) ng/mL, respectively. Of all the cross‐reacting steroids, α‐NT was the most reactive with the mAbs at 62% with NT‐1 mAb and 64% with NT‐2 mAb. Negligible cross‐reactivity (<0.01%) with other steroids was observed. Conclusion The establishment of these hybridomas allows the potential development of a rapid test kit, and may provide an alternative method for the detection of NT residues in food producing animals. | JIANQ JinQing ZHANG HaiTang YAO SiXin WANG ZiLiang WANG JianHua | 2011 | Biomedical and Environmental Sciences2011，24，2： | 2 |

| 11 | Convolutional neural network based detection and judgement of environmental obstacle in vehicle operation显示文摘Precise real-time obstacle recognition is both vital to vehicle automation and extremely resource intensive. Current deep-learning based recognition techniques generally reach high recognition accuracy, but require extensive processing power. This study proposes a region of interest extraction method based on the maximum difference method and morphology, and a target recognition solution created with a deep convolutional neural network. In the proposed solution, the central processing unit and graphics processing unit work collaboratively. Compared with traditional deep learning solutions, the proposed solution decreases the complexity of algorithm, and improves both calculation efficiency and recognition accuracy. Overall it achieves a good balance between accuracy and computation. | Guanqiu Qi Huan Wang Matthew Haner Chenjie Weng Sixin Chen Zhiqin Zhu | 2019 | CAAI Transactions on Intelligence Technology2019，4，2： | 1 |

| 14 | Effects of leptin on femoral fracture in rats显示文摘In this study, our objective was to evaluate effects of leptin on fracture healing in rats. Seventy two male SpragueDawley(SD) rats were randomized into 3 groups. Standardized femoral fractures were created in all the rats. Group A was treated with 1 mL normal saline(NS), group B with 0.3μg/kg leptin in 1 mL NS, and group C with 0.5μg/kg leptin in 1 mL NS for 2 weeks intraperitoneally. Each group was divided into three subgroups including 8 rats for evaluation at 2, 4 and 8 weeks. Radiological evaluation showed that callus formation of group B and C was all significantly higher than group A at 8 weeks(P=0.04 and P = 0.013, respectively). There was no statistically significant difference in fracture healing between group B and group C at 8 weeks(P = 0.197). Histological evaluation revealed fracture healing of group B and C was better than group A at 4 weeks(P=0.01 and P= 0.002,respectively) and 8 weeks(P = 0.008 and P= 0.003, respectively). Micro-computed tomography(Micro-CT) analysis demonstrated that greater amounts of bony callus and evidence of bone fusion were observed in group B and C at 4 weeks(P = 0.02 and P = 0.04, respectively) and 8 weeks(P= 0.005 and P = 0.001, respectively) compared to group A. Group C also had better fracture healing than group B at 8 weeks(P = 0.01). In conclusion, leptin has a positive effect on rat femoral fracture healing. | Lei Wang Sixin Sun Lei Yang Chun Lu Xiaojian Cao | 2018 | The Journal of Biomedical Research2018，32，2： | 1 |

| 16 | Physical-Layer Encryption in Massive MIMO Systems with Spatial Modulation显示文摘Massive multiple input and multiple output(MIMO) is a key technology of the fifth generation(5 G) wireless communication systems, which brings various advantages, such as high spectral efficiency and energy efficiency. In MIMO system, spatial modulation(SM) has recently emerged as a new transmission method. In this paper, in order to improve the security in SM-MIMO, a physical layer encryption approach named chaotic antenna-index three-dimensional modulation and constellation points rotated(CATMCPR) encryption scheme is proposed, which utilizes the chaotic theory and spatial modulation techniques. The conventional physical-layer encryption in SM-MIMO suffers from spectral efficiency(SE) performance degradation and usually needs a preshared key, prior channel state information(CSI) or excess jamming power. By contrast, we show that the CATMCPR scheme can not only achieve securely communication but also improve above drawbacks. We evaluate the performances of the proposed scheme by an analysis and computer simulations. | Sixin Wang Wei Li Jing Lei | 2018 | China Communications2018，15，10： | 1 |
