| 4 | Single titanium-oxide species implanted in 2D g-CsN4 matrix as a highly efficient visible-light CO2 reduction photocatalyst显示文摘A visible-light-response, efficie nt and robust photo-catalyst for CO2 reduction is highly desirable. Herein, we demonstrate that single titanium-oxide species impla nted in two-dime nsion al (2D) graphitic carb on n itride (g-C3N4) matrix (2D TiO-CN) can efficie ntly photo-catalyze the reduction of CO2 to CO under the irradiation of visible light. The synergistic interaction between single titanium oxide species and g-C3N4 in 2D TiO-CN not only enhances the separation of photo-excited charges, but also results in visible light response of single titanium-oxide species, realizing high activity of CO2 photo-reduction with extremely high CO generation rate of 283.9 pmol·h^-1·g^-1, 5.7, 6.8 and 292.2 times larger than those of TQ2/CN hybrid material, CN and commercial TiO2, respectively. Time-resolved fluoresce nee and electron spin resonance spectroscopy revealed the catalytic mechanism of the fabricated 2D TiO-CN photocatalysts for CO2 reduction. | Shangfeng Tang Xuepeng Yin Guanyu Wang Xiuli Lu Tongbu Lu | 2019 | Nano Research2019，12，2： | 8 |

| 6 | Quantitative Assessment of Impacts of Regional Climate and Human Activities on Saline-alkali Land Changes:A Case Study of Qian'an County,Jilin Province显示文摘Interdecadal and interannual variations of saline-alkali land area in Qian′an County, Jilin Province, China were comprehensively analyzed in this paper by means of satellite remote sensing interpretation, field flux observations and regional climate diagnosis.The results show that on the interannual scale, the impact of climate factors accounts for 71.6% of the total variation of the saline-alkali land area, and that of human activities accounts for 28.4%.Therefore the impact of climate factors is obviously greater than that of human activities.On the interdecadal scale, the impact of climate factors on the increase of the saline-alkali land area accounts for 43.2%, and that of human activities accounts for 56.8%.The impact of human activities on the variation of saline-alkali land area is very clear on the interdecadal scale, and the negative impact of human activities on the environment should not be negligible.Besides, changes in the area of heavy saline-alkali land have some indication for development of saline-alkali land in Qian′an County. | LIAN Yi WANG Jie TU Gang REN Hongling SHEN Baizhu ZHI Keguang LI Shangfeng GAO Zongting | 2010 | Chinese Geographical Science2010，20，1： | 3 |
| 7 | CsPb(I_(x)Br_(1-x))_(3) solar cells显示文摘Owing to its nice performance, low cost, and simple solution-processing, organic-inorganic hybrid perovskite solar cell(PSC) becomes a promising candidate for next-generation high-efficiency solar cells.The power conversion efficiency(PCE) has boosted from 3.8% to 25.2% over the past ten years. Despite the rapid progress in PCE, the device stability is a key issue that impedes the commercialization of PSCs. Recently, all-inorganic cesium lead halide perovskites have attracted much attention due to their better stability compared with their organic-inorganic counterpart. In this progress report, we summarize the properties of CsPb(IxBr1-x)3 and their applications in solar cells. The current challenges and corresponding solutions are discussed. Finally, we share our perspectives on CsPb(IxBr1-x)3 solar cells and outline possible directions to further improve the device performance. | Xue Jia Chuantian Zuo Shuxia Tao Kuan Sun Yixin Zhao Shangfeng Yang Ming Cheng Mingkui Wang Yongbo Yuan Junliang Yang Feng Gao Guichuan Xing Zhanhua Wei Lijun Zhang Hin-Lap Yip Mingzhen Liu Qing Shen Longwei Yin Liyuan Han Shengzhong Liu Lianzhou Wang Jingshan Luo Hairen Tan Zhiwen Jin Liming Ding | 2019 | Science Bulletin2019，64，20： | 2 |

| 9 | The Weakening Relationship between ENSO and the South China Sea Summer Monsoon Onset in Recent Decades显示文摘The El Ni?o-Southern Oscillation(ENSO) is traditionally regarded as the most important factor modulating the interannual variation of the South China Sea summer monsoon(SCSSM) onset. A preceding El Ni?o(La Ni?a) usually tends to be followed by a delayed(an advanced) monsoon onset. However, the close relationship between ENSO and SCSSM onset breaks down after the early-2000 s, making seasonal prediction very difficult in recent years. Three possible perspectives have been proposed to explain the weakening linkage between ENSO and SCSSM onset, including interdecadal change of the ENSO teleconnection(i.e., the Walker circulation), interferences of other interannual variability(i.e., the Victoria mode), and disturbances on intraseasonal time scales(i.e., the quasi-biweekly oscillation). By comparing the epochs of 1979–2001 and 2002–19, it is found that the anomalous tropical Walker circulation generated by ENSO is much weaker in the latter epoch and thus cannot deliver the ENSO signal to the SCSSM onset. Besides, in recent years, the SCSSM onset is more closely linked to extratropical factors like the Victoria mode, and thus its linkage with ENSO becomes weaker. In addition to these interannual variabilities, the intraseasonal oscillations like the quasi-biweekly oscillation can disrupt the slow-varying seasonal march modulated by ENSO. Thus, the amplified quasi-biweekly oscillation may also contribute to the weakening relationship after the early-2000 s. Given the broken relationship between ENSO and SCSSM onset, the extratropical factors should be considered in order to make skillful seasonal predictions of SCSSM onset, and more attention should be paid to the extended-range forecast based on intraseasonal oscillations. | Peng HU Wen CHEN Shangfeng CHEN Lin WANG Yuyun LIU | 2022 | Advances in Atmospheric Sciences2022，39，3： | 1 |

| 11 | Watts-level ultraviolet-CLED integrated light sources for efficient surface and air sterilization显示文摘With the epidemic of the coronavirus disease(COVID-19) infection, AlGaN-based ultraviolet-C light emitting diodes(UVC-LEDs) have attracted widespread attention for their sterilization application. However, the sterilization characters of high power integrated light sources(ILSs) haven’t been widely investigated before utilizing in public sanitary security. In this work,by integrating up to 195 UVC-LED chips, high power UVC-LED ILSs with a light output power(LOP) of 1.88 W were demonstrated. The UVC-LED ILSs were verified to have efficient and rapid sterilization capability, which have achieved more than99.9% inactivation rate of several common pathogenic microorganisms within 1 s. In addition, the corresponding air sterilization module based on them was also demonstrated to kill more than 97% of Staphylococcus albus in the air of 20 m3 confined room within 30 min. This work demonstrates excellent sterilization ability of UVC-LED ILSs with high LOP, revealing great potential of UVC-LEDs in sterilization applications in the future. | Wei Luo Tai Li Yongde Li Houjin Wang Ye Yuan Shangfeng Liu Weiyun Wang Qi Wang Junjie Kang Xinqiang Wang | 2022 | Journal of Semiconductors2022，43，7： | 1 |
| 12 | Successively Regioselective Electrosynthesis and Electron Transport Property of Stable Multiply Functionalized[60]Fullerene Derivatives显示文摘With the recent advance in chemical modification of fullerenes,electrosynthesis has demonstrated increasing importance in regioselective synthesis of novel fullerene derivatives.Herein,we report successively regioselective synthesis of stable tetra-and hexafunctionalized[60]fullerene derivatives.The cycloaddition reaction of the electrochemically generated dianions from[60]fulleroindolines with phthaloyl chloride regioselectively affords 1,2,4,17-functionalized[60]fullerene derivatives with two attached ketone groups and a unique addition pattern,where the heterocycle is rearranged to a[5,6]-junction and the carbocycle is fused to an adjacent[6,6]-junction.This addition pattern is in sharp contrast with that of the previously reported biscycloadducts,where both cycles are appended to[6,6]-junctions.The obtained tetrafunctionalized compounds can be successively manipulated to 1,2,3,4,9,10-functionalized[60]fullerene derivatives with an intriguing“S”-shaped configuration via a novel electrochemical protonation.Importantly,the stability of tetrafunctionalized[60]fullerene products allows them to be applied in planar perovskite solar cells as efficient electron transport layers. | Xing-Xing Yan Bairu Li Hao-Sheng Lin Fei Jin Chuang Niu Kai-Qing Liu Guan-Wu Wang Shangfeng Yang | 2020 | Research2020，，1： | 1 |

| 14 | Four-inch high quality crack-free AlN layer grown on a hightemperature annealed AlN template by MOCVD显示文摘In this work,based on physical vapor deposition and high-temperature annealing(HTA),the 4-inch crack-free high-quality AlN template is initialized.Benefiting from the crystal recrystallization during the HTA process,the FWHMs of X-ray rocking curves for(002)and(102)planes are encouragingly decreased to 62 and 282 arcsec,respectively.On such an AlN template,an ultra-thin AlN with a thickness of~700 nm grown by MOCVD shows good quality,thus avoiding the epitaxial lateral over-growth(ELOG)process in which 3-4μm AlN is essential to obtain the flat surface and high crystalline quality.The 4-inch scaled wafer provides an avenue to match UVC-LED with the fabrication process of traditional GaN-based blue LED,therefore significantly improving yields and decreasing cost. | Shangfeng Liu Ye Yuan Shanshan Sheng Tao Wang Jin Zhang Lijie Huang Xiaohu Zhang Junjie Kang Wei Luo Yongde Li Houjin Wang Weiyun Wang Chuan Xiao Yaoping Liu Qi Wang Xinqiang Wang | 2021 | Journal of Semiconductors2021，42，12： | 0 |

| 16 | 低分化型粘膜内早期胃癌淋巴结转移的危险因素和腹腔镜手术探讨(英文)显示文摘Objective:The aim of this study was to identify clinicopathological factors predictive of lymph node metastasis (LNM) in intramucosal poorly differentiated early gastric cancer (EGC), and further to expand the possibility of using laparoscopic surgery for the treatment of intramucosal poorly differentiated EGC. Methods:Data from 65 patients with intramucosal poorly differentiated EGC and surgically treated were collected, and the association between the clinicopathological factors and the presence of LNM was retrospectively analyzed by univariate and multivariate logistic regression analyses. Results:Univariate analysis showed that number of tumors, tumor size and lymphatic vessel involvement (LVI) were the significant and independent risk factors for LNM (all P < 0.05). The LNM rates were 5.0%, 18.2% and 66.7%, respectively. There was no LNM in 31 patients without the three risk clinicopathological factors. Conclusion:The number of tumors, tumor size, and LVI are independently associated with the presence of LNM in intramucosal poorly differentiated EGC. Thus, these three risk factors may be used to set as a simple criterion to expand the possibility of using laparoscopic surgery for the treatment of intramucosal poorly differentiated EGC. | Zhibin Huo Shubo Chen Jing Zhang Hua Li Dianchao Wu Tongshan Zhai Shuxia Wang Qihai Xiao Bingge Mu Shangfeng Luan Hongfeng Nie Yan Qin | 2012 | The Chinese-German Journal of Clinical Oncology2012，11，8： | 0 |

| 18 | Synergistic engineering of hole transport materials in perovskite solar cells显示文摘In this work,methylammonium lead triiodide(CH3NH3PbI3)perovskite solar cells with efficiencies higher than 18%were achieved using a new nanocomposite hole transport layer(HTL)by doping poly(ethylenedioxythiophene):poly(styrene sulfonate)(PEDOT:PSS)with a mixed dopant of polyaniline(PANI)and graphene oxide(GO).A synergistic engineering between GO,PANI,and PEDOT:PSS was accomplished to introduce additional energy levels between perovskite and PEDOT:PSS and increase the conductivity of PEDOT:PSS.Kelvin probe force microscope results confirmed that adding GO to PEDOT:PSS/PANI composite significantly reduced the average surface potential.This increased the open circuit voltage(Voc)to 1.05 V for the GO/PEDOT:PSS/PANI nanocomposite perovskite solar cells from the pristine PEDOT:PSS(Voc=0.95 V)and PEDOT:PSS/PANI(Voc=0.99 V).In addition,adding PANI to the HTLs substantially enhanced short circuit current density(Jsc).This was supported by the current sensing-atomic force microscopy(CS-AFM)and conductivity measurements.The PANI doped films showed superior electrical conductivity compared with those without PANI as indicated by CS-AFM results.PANI can fill the gaps between the microflakes of GO and give rise to more compact hole transport material(HTM)layer.This led to a higher Jsc after doping with PANI,which was consistent with the incident photon-to-current efficiency and electrochemical impedance spectroscopy results.The results of X-ray diffraction(XRD)and AFM indicated the GO/PANI doped HTMs significantly improved the crystallinity,topography,and crystal size of the perovskite film grown on their surface.A higher efficiency of 18.12%for p-i-n perovskite solar cells has been obtained by adding the mixed dopant of GO,PANI,and PEDOT:PSS,demonstrating better stability than the pristine PEDOT:PSS cell. | Sally Mabrouk Behzad Bahrami Hytham Elbohy Khan Mamun Reza Ashim Gurung Mao Liang Fan Wu Mingtai Wang Shangfeng Yang Qiquan Qiao | 2020 | InfoMat2020，2，5： | 0 |
| 19 | Pomegranate-like C_(60)@cobalt/nitrogen-codoped porous carbon for high-performance oxygen reduction reaction and lithium-sulfur battery显示文摘Porous carbon materials play essential roles in electrocatalysis and electrochemical energy storage.It is of significant importance to rationally design and tune their porous structure and active sites for achieving high electrochemical activity and stability.Herein,we develop a novel approach to tune the morphology of porous carbon materials(PCM)by embedding fullerene C_(60),achieving improved performance of oxygen reduction reaction(ORR)and lithium-sulfur(Li-S)battery.Owing to the strong interaction between C_(60)and imidazole moieties,pomegranate-like hybrid of Ow-embedded zeolitic imidazolate framework(ZIF-67)precursor is synthesized,which is further pyrolyzed to form C_(60)-embedded cobalt/nitrogen-codoped porous carbon materials(abbreviated as C_(60)@Co-N-PCM).Remarkably,the unique structure of C_(60)@Co-N-PCM offers excellent ORR electrocatalytic activity and stability in alkaline solutions,outperforming the commercial Pt/C(20 wt.%)catalyst.Besides,C_(60)@Co-N-PCM as a novel cathode delivers a high specific capacity of-900 mAh·g^(-1) at 0.2 C rate in Li-S batteries,which is superior to the pristine ZIF-67-derived PCM without embedding C_(60). | Jianhua Wu Shiyang Wang Zhanwu Lei Runnan Guan Muqing Chen Pingwu Du Yalin Lu Ruiguo Cao Shangfeng Yang | 2021 | Nano Research2021，14，8： | 0 |
| 20 | Fullerene modification of WO_(3) electron transport layer toward high-efficiency MA-free perovskite solar cells with eliminated light-soaking effect显示文摘In perovskite solar cells(PSCs),the light-soaking effect,which means device performance changes obviously under continuous light illumination,is potentially harmful to loaded devices as well as accurately assessing their efficiency.Herein,chemically stable tungsten trioxide(WO3)with high electron mobility is used as electron transport material in methylamine(MA)-free PSCs.However,the light-soaking effect is observed apparently in our devices.A fullerene derivative,C60 pyrrolidine Tris-acid(CPTA),is introduced to modify the interface between WO3 and perovskite(PVK)layers,which can bond with WO3 and PVK simultaneously,leading to the passivation of the defect and the suppression of trap-assisted nonradiative recombination.What is more,the introduction of CPTA can enhance the built-in electric field between WO3 and PVK layers,thereby facilitating the electron extraction and inhibiting the carrier accumulation at the interface.Consequently,the lightsoaking effect of WO3-based PSCs has been eliminated,and the power conversion efficiency has been boosted from 17.4%for control device to 20.5%for WO3/CPTA-based PSC with enhanced stability.This study gives guidance for the design of interfacial molecules to eliminate the light-soaking effect. | Xin Yu Bing Cai Jinxia Zhang Xingcheng Li Xue Wang Gongtao Duan Wenfeng Zhang Xinhang Liu Wen-Hua Zhang Shangfeng Yang | 2023 | Interdisciplinary Materials2023，2，3： | 0 |
