| 1 | Dislocation-strained MoS_(2)nanosheets for high-efficiency hydrogen evolution reaction显示文摘Defect engineering is one of the effective strategies to optimize the physical and chemical properties of molybdenum disulfide(MoS_(2))to improve catalytic hydrogen evolution reaction(HER)performance.Dislocations,as a typical defect structure,are worthy of further investigation due to the versatility and sophistication of structures and the influence of local strain effects on the catalytic performance.Herein,this study adopted a low-temperature hydrothermal synthesis strategy to introduce numerous dislocation-strained structures into the in-plane and out-of-plane of MoS_(2)nanosheets.Superior HER catalytic activity of 5.85 mmol·g^(−1)·h^(−1)under visible light was achieved based on the high-density dislocations and the corresponding strain field.This work paves a new pathway for improving the catalytic activity of MoS_(2)via a dislocation-strained synergistic modulation strategy. | Shihao Wang Longlu Wang Lingbin Xie Weiwei Zhao Xia Liu Zechao Zhuang YanLing Zhuang Jing Chen Shujuan Liu Qiang Zhao | 2022 | Nano Research2022，15，6： | 2 |
| 2 | Mitochondria-localized iridium(Ⅲ) complexes with anthraquinone groups as effective photosensitizers for photodynamic therapy under hypoxia显示文摘Photodynamic therapy(PDT)is a potential way for the tumor treatment.However,it notably suffers the limitation of hypoxia in solid tumors.Thus,it is significant to develop effective photosensitizers which can exhibit excellent therapeutic performance under both normoxia and hypoxia.Herein,we reported four ionic iridium(Ⅲ)complexes(Irl-Ir4)with anthraquinone groups which can regulate their excited state energy levels effectively.Among them,the energy gap of Ir1 was between 1.63 and 2.21 eV,which can match well with that of O2,and the HOMO energy of Ir1 is less than-5.51 eV.Compared with Ir2-Ir4,the luminescent quantum efficiency of Irl was the highest.Particularly,Ir1 can specifically target the mitochondria of the tumor cells.Meanwhile,Ir1 showed high singlet oxygen quantum yields(Ф△)in both solutions and living cells with low cytotoxicity.The results of PDT experiments revealed that Irl,as a photosensitizer,exhibited excellent therapeutic effect not only in normoxia but also in hypoxia condition.We believe that this work is meaningful for developing excellent PDT agents based on cyclometalated Ir(III)complexes via rational ligand modification. | Song Guo Meiping Han Ruizhe Chen Yanling Zhuang Liang Zou Shujuan Liu Wei Huang Qiang Zhao | 2019 | Science China Chemistry2019，62，12： | 1 |
| 3 | Circularly polarized luminescence from organic micro-/nano-structures显示文摘Circularly polarized light exhibits promising applications in future displays and photonic technologies.Circularly polarized luminescence(CPL)from chiral luminophores is an ideal approach to directly generating circularly polarized light,in which the energy loss induced by the circularly polarized filters can be reduced.Among various chiral luminophores,organic micro-/nano-structures have attracted increasing attention owing to the high quantum efficiency and luminescence dissymmetry factor.Herein,the recent progress of CPL from organic micro-/nano-structures is summarized.Firstly,the design principles of CPL-active organic micro-/nano-structures are expounded from the construction of micro-/nano-structure and the introduction of chirality.Based on these design principles,several typical organic micro-/nano-structures with CPL activity are introduced in detail,including self-assembly of small molecules,self-assembly ofπ-conjugated polymers,and self-assembly on micro-/nanoscale architectures.Subsequently,we discuss the external stimuli that can regulate CPL performance,including solvents,pH value,metal ions,mechanical force,and temperature.We also summarize the applications of CPL-active materials in organic light-emitting diodes,optical information processing,and chemical and biological sensing.Finally,the current challenges and prospects in this emerging field are presented.It is expected that this review will provide a guide for the design of excellent CPL-active materials. | Yonging Deng Mengzhu Wang Yanling Zhuang Shujuan Liu Wei Huang Qiang Zhao | 2021 | Light(Science & Applications)2021，10，5： | 1 |
| 4 | Effects of rodent-induced disturbance on eco-physiological traits of Haloxylon ammodendron in the Gurbantunggut Desert,Xinjiang,China显示文摘Disturbance by rodents alters the morphologies and nutrients of plants as well as the physical-chemical properties of the soils.Changes in plants are considered to be mechanisms of defense against the disturbance by rodents.Rodents gnaw on the assimilating branches of Haloxylon ammodendron(CA Mey.)Bunge and burrow under the bushes in the desert ecosystems of Xinjiang,China.However,eco-physiological responses of different age groups of H.ammodendron to the disturbance by rodents are not well understood.In this study,soil physical-chemical properties under the shrubs and the above-ground morphological,physiological and biochemical features of assimilating branches of H.ammodendron of different age groups(i.e.,young,30−100 cm;middle-aged,100−200 cm;and mature,>200 cm)in burrowed and non-burrowed(control)areas were studied in 2018.We found that disturbance by rodents significantly increased the crown width and total branching rates of young and middle-aged H.ammodendron.Photosynthetic pigment contents of assimilating branches of H.ammodendron were significantly reduced under the disturbance by rodents.In term of plant nutrients,the main differences among different age groups of H.ammodendron under the disturbance by rodents occurred in the total soluble sugar and reducing sugar contents that decreased in young plants,increased in middle-aged plants,and did not affect in mature plants.Crude protein and phosphorus contents significantly increased,while crude fiber and calcium contents significantly decreased in young plants.Crude fat and calcium contents significantly decreased in middle-aged plants.Soil organic matter(SOM),total nitrogen(TN),available nitrogen(AN)and available potassium(AK)contents in the topsoil(0–20 cm),which are conducive to forming''fertile islands'',also increased under the disturbance by rodents.In particular,soil AN and AK were the major factors affecting the above-ground morphological characteristics of H.ammodendron in burrowed areas.Overall,the response and defense strategies of H.ammodendron to the disturbance by rodents differed among different age groups,and the effect of the disturbance by rodents on H.ammodendron gradually weakened with the increasing plant age. | XIANG Yanling WANG Zhongke LYU Xinhua HE Yaling LI Yuxia ZHUANG Li ZHAO Wenqin | 2020 | Journal of Arid Land2020，12，3： | 1 |

| 6 | Diverse atomic structure configurations of metal-doped transition metal dichalcogenides for enhancing hydrogen evolution显示文摘Doping foreign metal atoms into the substrate of transition metal dichalcogenides(TMDs)enables the formation of diverse atomic structure configurations,including isolated atoms,chains,and clusters.Therefore,it is very important to reasonably control the atomic structure and determine the structure-activity relationship between the atomic configurations and the hydrogen evolution reaction(HER)performance.Although numerous studies have indicated that doping can yield diverse atomic structure configurations,there remains an incomplete understanding of the relationship between atomic configurations within the lattice of TMDs and their performance.Here,diverse atomic structure configurations of adsorptive doping,substitutional doping,and TMDs alloys are summarized.The structure-activity relationship between different atomic configurations and HER performance can be determined by micro-nanostructure devices and density functional theory(DFT)calculations.These diverse atomic structure configurations are of great significance for activating the inert basal plane of TMDs and improving the catalytic activity of HER.Finally,we have summarized the current challenges and future opportunities,offering new perspectives for the design of highly active and stable metal-doped TMDs catalysts. | Longlu Wang Yuxin Zhang Chen Gu Haoxuan Yu Yanling Zhuang Zechao Zhuang | 2024 | Nano Research2024，17，5： | 0 |
| 7 | Soluble triarylamine functionalized symmetric viologen for all-solid-state electrochromic supercapacitors显示文摘Electrochromic supercapacitors have drawn enormous attention due to their ability to monitor the charge and discharge processes through color changes of electroactive materials.However,there are few work on small organic molecules as active materials for all-solid-state electrochromic supercapacitors.Herein,we reported two novel multifunctional symmetric viologens(TPA-bpy and CZ-bpy),which showed different solvatochromic,electrochromic,electroluminochromic and energy storage behaviors despite their similar chemical structures.The different performances between these two viologens were attributed to the difference in the intramolecular charge transfer capability and the solubility in organic solvents.Devices containing TPA-bpy displayed faster response time and higher coloration efficiency due to the introduction of packing-disruptive and three-dimensional triarylamine groups.Moreover,devices containing TPA-bpy also showed energy storage characteristics with an obvious color change from purple to yellow.It showed a wide voltage window(2.0 V),long discharge time(230.3 s at 0.01 mA cm−2),and excellent cycling stability with 90%capacitance retention after 6,000 cycles.The work provides a new and convenient strategy towards the development of novel electrochromic capacitive materials. | Yanling Zhuang Weiwei Zhao Longlu Wang Feiyang Li Weikang Wang Shujuan Liu Wei Huang Qiang Zhao | 2020 | Science China Chemistry2020，63，11： | 0 |
| 8 | Optimized photocatalytic regeneration of adsorption-photocatalysis bifunctional composite saturated with Methyl Orange显示文摘Photo-responsive adsorption-photocatalysis nanocomposites are generally used in water and wastewater decontamination;however,the prolonged adsorption capacity of composites and the role of adsorption in concomitant photocatalysis are typically neglected.These composites can be regenerated under light irradiation as their adsorption capacity decreases.Herein,a novel adsorption-photocatalysis bifunctional nanocomposite,Bi-doped TiO2 supported on powdered activated carbon(Bi2O3/TiO2/PAC),was prepared using the solimpregnation-hydrothermal procedure.Bi2O3/TiO2/PAC with a secondary calcination temperature of 700℃under a nitrogen atmosphere was selected for maximum adsorption capacity on Methyl Orange(MO).The composite displayed an excellent adsorption capacity and was easily separated and recycled.The results demonstrate that 71.2%photocatalytic regeneration efficiency could be attained under visible light irradiation for 1 hr at an intensity of 750 W/m^2 and pH 7.Characterization of the as-prepared Bi2O3/TiO2/PAC nanocomposite(700℃)indicates that it possesses a highly specific surface area and great optical properties,showing bifunctional adsorption-photocatalysis characteristics.The p-n heterojunction of the composite played a dominant role in the photocatalytic regeneration process,and effective degradation of MO could be achieved along with composite regeneration. | Yi Shang Xing Li Yanling Yang Nan Wang Xiaoxuan Zhuang Zhiwei Zhou | 2020 | Journal of Environmental Sciences2020，32，8： | 0 |
| 9 | High-performance bulk heterojunction-based photocathode with facile architecture for photoelectrochemical water splitting显示文摘Organic semiconductors are promising candidates as photoactive layers for photoelectrodes used in photoelectrochemical(PEC)cells due to their excellent light absorption and efficient charge transport properties with the help of interfacial materials.However,the use of multilayers will make the charge transfer mechanism more complicated and decrease the PEC performance of the photoelectrode caused by the increased contact resistance.In this work,a PM6:Y6 bulk heterojunction(BHJ)-based photocathode is fabricated for efficient PEC hydrogen evolution reaction(HER)in an acidic aqueous solution.With RuO_(2)as an interfacial modification layer,the photocathode with a simple structure(fluorine-doped tin oxide(FTO)/PM6:Y6/RuO_(2))generates a maximum photocurrent density up to-15 m A/cm^(2)at 0 V vs.reference hydrogen electrode(RHE),outperforming all previously reported BHJ-based photocathodes in terms of PEC performance.The highest ratiometric power-saved efficiency of 3.7%is achieved at 0.4 V vs.RHE. | Yanling Wu Deyu Liu Huanglong Zhuang Jiabo Le Yongbo Kuang | 2023 | Chinese Chemical Letters2023，34，1： | 0 |
| 10 | Regulation of activin A in cell proliferation and hormone secretion by human normal trophoblast cells显示文摘Regulation of activin A in cell proliferation as well as hCG and progesterone secretion was investigated using primary cultured cytotrophoblast cells and normal placenta origin cytotrophoblast cell line-NPC cells in serum-free system. It was shown that activin A promoted hCG and progesterone secretion in primary cultured cytotrophoblast cells as well as progesterone secretion in NPC cells, while it had no effect on cell proliferation and hCG secretion in NPC cells. lmportant evidence is provided for the autocrine regulatory mechanism of activin A on hormone secretion in placental trophoblast cells at early pregnancy. | Yanling Wang J.
