| 1 | Construction of Photoresponsive 3D Structures Based on Triphenylethylene Photochromic Building Blocks显示文摘Photoresponsive materials have been widely used in sensing,bioimaging,molecular switches,information storage,and encryption nowadays.Although a large amount of photoresponsive materials have been reported,the construction of these smart materials into precisely prescribed complex 3D geometries is rarely studied.Here we designed a novel photoresponsive material methyl methacrylate containing triphenylethylene(TrPEF_(2)-MA)that can be directly used for digital light processing(DLP)3D printing.Based on TrPEF_(2)-MA,a series of photoresponsive 3D structures with reversible color switching under ultraviolet/visible light irradiations were fabricated.These complex photoresponsive 3D structures show high resolutions(50μm),excellent repeatability(25 cycles without fatigue),and tunable saturate color degrees.Multicomponent DLP 3D printing processes were also carried out to demonstrate their great properties in information hiding and information-carrying properties.This design strategy for constructing photoresponsive 3D structures is attractive in the area of adaptive camouflage,information hiding,information storage,and flexible electronics. | Xiayu Zhang Fukang Liu Beibei Du Rongjuan Huang Simin Zhang Yunfei He Hailan Wang Jingjing Cui Biao Zhang Tao Yu Wei Huang | 2022 | Research2022，，4： | 1 |

| 3 | Building Ultra-Stable and Low-Polarization Composite Zn Anode Interface via Hydrated Polyzwitterionic Electrolyte Construction显示文摘Aqueous zinc metal batteries are noted for their costeffectiveness,safety and environmental friendliness.However,the water-induced notorious issues such as continuous electrolyte decomposition and uneven Zn electrochemical deposition remarkably restrict the development of the long-life zinc metal batteries.In this study,zwitterionic sulfobetaine is introduced to copolymerize with acrylamide in zinc perchlorate(Zn(ClO;);)solution.The designed gel framework with hydrophilic and charged groups can firmly anchor water molecules and construct ion migration channels to accelerate ion transport.The in situ generated hybrid interface,which is composed of the organic functionalized outer layer and inorganic Clcontaining inner layer,can synergically lower the mass transfer overpotential,reduce water-related side reactions and lead to uniform Zn deposition.Such a novel electrolyte configuration enables Zn//Zn cells with an ultra-long cycling life of over 3000 h and a low polarization potential(~0.03 V)and Zn//Cu cells with high Coulombic efficiency of 99.18%for 1000 cycles.Full cells matched with MnO;cathodes delivered laudable cycling stability and impressive shelving ability.Besides,the flexible quasi-solid-state batteries which are equipped with the anti-vandalism ability(such as cutting,hammering and soaking)can successfully power the LED simultaneously.Such a safe,processable and durable hydrogel promises significant application potential for long-life flexible electronic devices. | Qiong He Guozhao Fang Zhi Chang Yifang Zhang Shuang Zhou Miao Zhou Simin Chai Yue Zhong Guozhong Cao Shuquan Liang Anqiang Pan | 2022 | Nano-Micro Letters2022，14，6： | 1 |

| 5 | Orthogonal carbazole-perylene bisimide pentad:a photoconversion-tunable photosensitizer with diversified excitation and excited-state relaxation pathways显示文摘Integrating multiple photosensitive properties into an“all-in-one”photosensitizer(PS)shows great promise for the treatment of cancers owing to synergistic effect among them.However,the development of such PSs,especially those that need a single laser source,remains a challenge.Herein,we report an orchestration of electron donors and acceptors in a propeller-like pentad,PBI-4Cz,where four carbazole(Cz)units are covalently linked to the ortho-positions of the perylene bisimide(PBI)core.Strong intramolecular donor-acceptor interaction significantly quenches the luminescence and largely extends the absorption spectra to near-infrared region.Excited-state dynamics investigated via femto-and nano-second transient absorption spectroscopy revealed exclusive charge separation of the PBI-4Cz within initial 0.5 ps when photoexcited regardless of which intermediate is involved.Energy dissipation of the resulting charge-separated state(PBI^(•−)-4Cz^(•−))is subjected to the toggle between intersystem-crossing toward excited triplet states and charge recombination toward ground states.Relative importance of the two pathways can be tuned by micro-environmental polarity,which endows PBI-4Cz remarkable performances of singlet-oxygen generation(>90.0%)in toluene and photothermal conversion(∼28.6%)in DMSO.Harnessing intrinsic photostability and excited-state processes of heavy-atom-free PBI derivatives not only holds a promise for multifunctional phototheranostics,but also provides a prototype for designing high-performance PSs with tunable photoconversion pathways. | Zhaolong Wang Yue Sun Simin Lin Gang Wang Xingmao Chang Xinyu Gou Taihong Liu Shengye Jin Gang He Yu-Chen Wei Pi-Tai Chou Yu Fang | 2021 | Science China Chemistry2021，64，12： | 0 |
| 6 | Changing profile of lung cancer clinical characteristics in China:Over 8-year population-based study显示文摘Background:Although examinations and therapies for bronchial lung cancer,also called lung cancer(LC),have become more effective and precise,the morbidity and mortality of LC remain high worldwide.Describing the changing profile of LC characteristics over time is indispensable.This study aimed to understand the changes in real-world settings of LC and its characteristics in China.Methods:In this study,119,785 patients were enrolled from 2012 to 2020 in the Shanghai Pulmonary Hospital.The patients’medical records were extracted from the hospital’s database.Demographic characteristics,general clinicopathological information,and blood coagulation indices at the initial diagnoses were analyzed using the Kruskal-Wallis,Nemenyi,chi-squared,and Bonferroni tests.Changes in demographic characteristics during the 8-year study period,namely dynamic changes among different stages and different pathological types,were evaluated.Results:The percentages of female(from 38.50%[323/839]in 2012 to 48.29%[5112/10,585]in 2020)and non-smoking LC(from 69.34%[475/685]to 80.48%[8055/10,009])patients increased significantly during the study period,with a trend toward a younger age at diagnosis(from 3.58%[30/839]to 8.99%[952/10,585]).Over the study period,the proportion and absolute number of lung adenocarcinoma cases increased(from 67.97%[433/637]to 76.31%[6606/8657])while the proportion of lung squamous cell carcinoma decreased(from 21.19%[135/637]to 12.08%[1046/8657]).Comprehensive driver gene mutation examination became more common,and epidermal growth factor receptor(EGFR)mutation occurred more frequently in female vs.male(62.03%[12793/20625]vs.29.90%[8207/27,447])and non-smoking vs.smoking(53.54%[17,203/32,134]vs.23.73%[3322/13,997])patients(both P<0.001).The distribution of the common driver genes differed among different stages of LC.EGFR mutation was detected most frequently at each stage,and other driver gene alterations were more common in advanced stages(P<0.001).The combination of chemotherapy,targeted ther-apy,and immunotherapy,as a comprehensive management regimen,gradually became predominant over the study period(P<0.001).A hypercoagulable state was shown in advanced-stage LC patients and patients with the anaplastic lymphoma kinase fusion,indicated by significantly elevated levels of d-dimer,fibrinogen,and fibrinogen degradation products.Conclusions:This study comprehensively depicted the changing characteristics of Chinese LC patients over an 8-year period to provide preliminary insights into LC treatment.Trial registration:ClinicalTrials.gov,NCT05423236. | Kandi Xu Hao Wang Simin Li Lishu Zhao Xinyue Liu Yujin Liu Li Ye Xiaogang Liu Linfeng Li Yayi He | 2023 | Chinese Medical Journal Pulmonary and Critical Care Medicine2023，1，3： | 0 |
| 7 | Tunable phase transition, band gap and SHG properties by halogen replacement of hybrid perovskites [(thiomorpholinium)PbX_(3), X = Cl,Br,I]显示文摘By the replacement of halogen anion,three new multifunctional organic-inorganic hybrid perovskites(thiomorpholinium)PbX_(3)(X=Cl,Br,I)were successfully synthesized and underwent reversible struc-tural transformation above room temperature,accompanied by the anomalous change of dielectric con-stant.With the adjustment of the halogen anion from Cl to I in the inorganic skeleton,the space group is transformed from centrosymmetric space group P2_(1)/c((thiomorpholinium)PbCl_(3))to chiral one P2_(1)2_(1)2_(1)((thiomorpholinium)PbBr3,(thiomorpholinium)PbI_(3))at room temperature.The ordered-disordered tran-sition of organic cations and the change of hydrogen bonds with the increase of temperature lead to above-room-temperature phase transitions.Ultraviolet absorption and second-harmonic generation(SHG)measurements confirmed that both the band gap and SHG activity of(thiomorpholinium)PbX_(3)(X=Cl,Br,I)crystals were tunable.The band gaps reveal a broadening trend with 3.532 e V,3.410 e V and 3.175 e V along the Cl→Br→I series.This work provides an effective molecular design for multifunctional organic-inorganic perovskites. | Simin Liu Lei He Yuzhen Wang Pingping Shi Qiong Ye | 2022 | Chinese Chemical Letters2022，33，2： | 0 |
| 8 | Biodegradable composite polymer as advanced gel electrolyte for quasi-solid-state lithium-metal battery显示文摘The development of low-cost and eco-friendly gel polymer electrolytes (GPEs) with a wide window, ideal compatibility, and structural stability is an effective measure to achieve safe high-energy-density lithium-metal batteries. Herein, a biodegradable composite polyacrylonitrile/poly-L-lactic acid nanofiber membrane (PAL) is synthesized and used as a robust skeleton for GPEs. The 3D nanofiber membrane (PAL-3-C12) prepared with an adjusted weight ratio of polyacrylonitrile (PAN)/poly-L-lactic acid (PLLA) and spinning solution concentration delivers decent thermal stability, biodegradability, and liquid electrolyte absorbability. The “passivation effect” of PAN upon lithium metal is effectively alleviated by hydrogen bonds formed in the PAL chains. These advantages enable PAL GPEs to work stably to 5.17 V while maintaining high ionic conductivity as well as excellent corrosion resistance and dielectric properties. The interfacial compatibility of optimized GPEs promotes the stable operation of a Li||PAL-3-C12 GPEs||Li symmetric battery for 1000 h at 0.15 mA cm^(−2)/0.15 mA h cm^(−2), and the LiFePO4 full cell retains capacity retention of 97.63% after 140 cycles at 1C. | Simin Chai Yangpu Zhang Yijiang Wang Qiong He Shuang Zhou Anqiang Pan | 2022 | eScience2022，2，5： | 0 |
| 9 | Geological evolution of offshore pollution and its long-term potential impacts on marine ecosystems显示文摘Populations and metropolitan centers are accumulated in coastal areas around the world.In view of the fact that they are geographically adjacent to coasts and intense anthropogenic activities,increasing global offshore pollution has been an important worldwide concern over the past several decades and has become a very serious problem that needs to be addressed urgently.Due to offshore pollution,various geological disasters occur in high frequency,including intensified erosion and salinization of coastal soils,frequent geological collapses and landslides and increasing seismic activities.Moreover,offshore pollution shows increasingly serious impacts on the topography and geomorphology of offshore and coastal areas,including coastal degradation,retreating coastlines and estuary delta erosion.Offshore sedimentation processes are strongly influenced by the pH changes of terrestrial discharges,and sedimentary dynamics have become extremely acute and complex due to offshore pollution.The seabed topography and hydrodynamic environment determine the fate and transport of pollutants entering offshore regions.Coastal estuaries,port basins and lagoons that have relatively moderate ocean currents and winds are more likely to accumulate pollutants.Offshore regions and undersea canyons can be used as conduits for transporting pollutants from the continent to the seabed.It is particularly noteworthy that the spatial/temporal distribution of species,community structures,and ecological functions in offshore areas have undergone unprecedented changes in recent decades.Due to increasing offshore pollution,the stable succession and development trend of marine ecosystems has been broken.It is thus important to identify and regulate the quantity,composition and transportation of pollutants in offshore regions and their behavior in marine ecosystems.In particular,crucial actions for stabilizing marine ecosystems,including increasing species and biodiversity,should be implemented to enhance their anti-interference capabilities.This review provides an overview of the current situation of offshore pollution,as well as major trends of pollutant fate and transportation from continent to marine ecosystems,transformation of pollutants in sediments,and their bioaccumulation and diffusion.This study retrospectively reviews the long-term geological evolution of offshore pollution from the perspective of marine geology,and analyses their long-term potential impacts on marine ecosystems.Due to ecological risks associated with pollutants released from offshore sediments,more research on the influence of global offshore pollution based on marine geology is undoubtedly needed. | Qixing Zhou Simin Wang Jiaqi Liu Xiangang Hu Yuxia Liu Yuqing He Xuan He Xiaotong Wu | 2022 | Geoscience Frontiers2022，13，5： | 0 |
| 10 | China-CIMMYT collaboration enhances wheat improvement in China显示文摘China and CIMMYT have collaborated on wheat improvement for over 40 years and significant progress has been achieved in five aspects in China.A standardized protocol for testing Chinese noodle quality has been established with three selection criteria, i.e.,gluten quality, starch viscosity and flour color are identified as being responsible for noodle quality.Genomic approaches have been used to develop and validate genespecific markers, leading to the establishment of a KASP platform, and seven cultivars have been released through application of molecular marker technology.Methodology for breeding adult-plant resistance to yellow rust, leaf rust and powdery mildew, based on the pleiotropic effect of minor genes has been established, resulting in release of six cultivars.More than 330 cultivars derived from CIMMYT germplasm have been released and are now grown over 9% of the Chinese wheat production area.Additionally, physiological approaches have been used to characterize yield potential and develop high-efficiency phenotyping platforms.CIMMYT has also provided valuable training for Chinese scientists.Development of climate-resilient cultivars with application of new technology will be the priority for future collaboration. | Zhonghu HE Xianchun XIA Yong ZHANG Yan ZHANG Yonggui XIAO Xinmin CHEN Simin LI Yuanfeng HAO Awais RASHEED Zhiyong XIN Qiaosheng ZHUANG Ennian YANG Zheru FAN Jun YAN Ravi SINGH Hans-Joachim BRAUN | 2019 | Frontiers of Agricultural Science and Engineering2019，6，3： | 0 |
