| 5 | Dynamic simulation of tropical coral reef ecosystem being disturbed by multiple situations显示文摘In consideration of the rapid degradation of coral reef ecosystems, the establishment of models is helpful to comprehend the degradation mechanism of coral reef ecosystems and predict the development process of coral reef communities. According to the characteristics of complex ecosystem of tropical coral reefs in China, the coral reef functional group is the core level variable;combined with the multiple feedback effects of coral reef functional groups and environmental changes, the study presents a coral reef ecosystem dynamics model with hermatypic corals as the core. Based on the simulation of the assumed initial value and the internal feedback of the system, the results show that in the basic simulation(relative health conditions), the coverage area of live corals and coral reefs generally decreased first and then increased, and increased by 4.67% and 6.38% between2010 and 2050, respectively. Based on the calibration model and the current situation of the studied area, the multi-factor disturbance effects of coral reef communities were simulated and explored by setting up three scenarios involving fishing policy, terrestrial deposition, and inorganic nitrogen emissions. Among them, in the single factor disturbance, the fishing policy exerts the most direct impact on the community decline;and the succession phenomenon is obvious;the terrestrial sedimentation has a faster and more integrated effect on the community decline;the effect of inorganic nitrogen emission on the community decline is relatively slow. In the double/multi-factor disturbance, the superimposed disturbance will aggravate the multi-source feedback effect of the coral reef communities development, accelerate the community decay rate, and make its development trajectory more complicated and diverse. This method provides a scientific and feasible method for simulating the damage of long-term coral reef community and exploring the development law and adaptive management of coral reef ecosystems. In the future, it can be further studied in the ecological restoration process and decisionmaking direction of coral reefs. | Geng Wang Rui Dong Huimin Xu Dewen Ding | 2021 | Acta Oceanologica Sinica2021，40，9： | 1 |

| 7 | Robust,Breathable and Flexible Smart Textiles as Multifunctional Sensor and Heater for Personal Health Management显示文摘Smart textiles with high sensitivity and rapid response for various external stimuli have gained tremendous attentions in human healthcare monitoring,personal heat management,and wearable electronics.However,the current smart textiles only acquire desired signal passively,regularly lacking subsequent on-demand therapy actively.Herein,a robust,breathable,and flexible smart textiles as multi-function sensor and wearable heater for human health monitoring and gentle thermotherapy in real time is constructed.The composite fiber as strain sensor(CFY@PU)was fabricated via warping carbon fiber yarns(CFY)onto polyurethane fibers(PU),which endowed composite fiber with high conductivity,excellent sensitivity(GF=76.2),and fantastic dynamic durability(7500 cycles)in strain sensing.In addition,CFY@PU can detect various degrees of human movements such as elbow bending,swallowing and pulse,which can provide effective information for disease diagnosis.More surprisingly,weaving CFY@PU into a fabric can assemble highly sensitive pressure sensor for remote communication and information encryption.Warping CFY onto Kevlar would obtain temperature-sensitive composite fiber(CFY@Kevlar)as temperature sensor and wearable heater for on-demand thermotherapy,which provided unique opportunities in designing smart textiles with ultrahigh sensitivity,rapid response,and great dynamic durability. | Dewen Xu Zhaofeng Ouyang Yanjuan Dong Hou‑Yong Yu Shuang Zheng Shenghong Li Kam Chiu Tam | 2023 | Advanced Fiber Materials2023，5，1： | 0 |
| 8 | Ion-induced white-light-emitting polymeric hydrogels with high mechanical strength and reversible stimuli-responsive properties显示文摘We have developed a facile strategy to fabricate model multicolor hydrogels via a straightforward mixing process of poly acrylonitrile-grafted methacrylamide(PANMAM),polymethacrylic acid(PMAA)and doped lanthanide(Eu/Tb)and zinc ions to form the interpenetrating dual-polymer gel networks.The hydrogels exhibit excellent tunability of multi-spectrum emission colors(including white light)by simply varying the stoichiometry of metal ions.Furthermore,taking the advantage of different metal ion response mechanisms,we have demonstrated the reversible acidity/alkalinity stimuli-responsive behaviors of white-light-emitting hydrogel(WLE gel).Meanwhile,the unique cross-linked network formed through hydrogen-bonding,metal-ligand coordination and ionic interaction is introduced to achieve favorable mechanical strength of hydrogels.These properties enable the possibility in obtaining fluorescent patterns on hydrogels,which are promising candidate for encrypted information with improved security. | Shanshan Chen Liying Yin Lin Liu Ning Zhang Dewen Dong | 2021 | Chinese Chemical Letters2021，32，10： | 0 |

| 10 | Designing high-efficiency light-to-thermal conversion materials for solar desalination and photothermal catalysis显示文摘Light-to-thermal conversion materials(LTCMs)have been of great interest to researchers due to their impressive energy conversion capacity and wide range of applications in biomedical,desalination,and synergistic catalysis.Given the limited advances in existing materials(metals,semiconductors,π-conjugates),researchers generally adopt the method of constructing complex systems and hybrid structures to optimize performance and achieve multifunctional integration.However,the development of LTCMs is still in its infancy as the physical mechanism of light-to-thermal conversion is unclear.In this review,we proposed design strategies for efficient LTCMs by analyzing the physical process of light-tothermal conversion.First,we analyze the nature of light absorption and heat generation to reveal the physical processes of light-to-thermal conversion.Then,we explain the light-to-thermal conversion mechanisms of metallic,semiconducting andπ-conjugated LCTMs,and propose new material design strategies and performance improvement methods.Finally,we summarize the challenges and prospects of LTCMs in emerging applications such as solar water evaporation and photothermal catalysis. | Hanjin Jiang Xinghang Liu Dewen Wang Zhenan Qiao Dong Wang Fei Huang Hongyan Peng Chaoquan Hu | 2023 | Journal of Energy Chemistry2023，，4： | 0 |
| 11 | Outer delocalized electron aggregation of bromide bridged core–shell CuBr@C for hydrogen evolution reaction显示文摘Modulation of the surface electron distribution is a challenging problem that determines the adsorption ability of catalytic process.Here,we address this challenge by bridging the inner and outer layers of the core–shell structure through the bridge Br atom.Carbon shell wrapped copper bromide nanorods(CuBr@C)are constructed for the first time by chemical vapour deposition with hexabromobenzene(HBB).HBB pyrolysis provides both bridge Br atom and C shells.The C shell protects the stability of the internal halide structure,while the bridge Br atom triggers the rearrangement of the surface electrons and exhibits excellent electrocatalytic activity.Impressively,the hydrogen evolution reaction(HER)activity of CuBr@C is significantly better than that of commercial N-doped carbon nanotubes,surpassing commercial Pt/C at over 200 mA·cm^(−2).Density functional theory(DFT)calculations reveal that bridge Br atoms inspire aggregation of delocalized electrons on C-shell surfaces,leading to optimization of hydrogen adsorption energy. | Tianyi Xu Ruoyu Li Lei Zhang Dongxu Jiao Yilong Dong Ming Gong Dantong Zhang Jinchang Fan Dewen Wang Yanhua Liu Xiao Zhao Wei Zhang Weitao Zheng Xiaoqiang Cui | 2023 | Nano Research2023，16，5： | 0 |
| 12 | Polymer brushes on hydrogen-terminated silicon substrates via stable Si--C bond显示文摘We demonstrate a straightforward and efficient method for the creation of polymer brushes on hydrogen-terminated silicon substrates through the UV-induced photopolymerization. The surface grafting polymerization is applicable to a series of monomers, allowing the direct formation of homogeneous polymer coatings ranging from hydrophilic poly(2-isopropenyl-2-oxazoline)(PIPOx),amphiphilic poly(N-isopropyl acrylamide)(PNIPAM), to hydrophobic polystyrene(PS) and poly(4-(1H,1H,2H,2H-perfluorohexyl)oxymethylstyrene)(PPHMS) on Si(100) and Si(111) surfaces via stable Si—C bonds. Polymerization kinetic investigation indicates a linear increase of polymer layer thickness with the polymerization time. Moreover, the as-prepared polymer brushes exhibit superior stability against basic conditions in contrast to those that were formed on silicon substrates via conventional Si—O—C bond. | Hang Bian Xiaozhe Dong Shanshan Chen Dewen Dong Ning Zhang | 2018 | Chinese Chemical Letters2018，29，1： | 0 |
| 13 | Atomic Dispersed Hetero‑Pairs for Enhanced Electrocatalytic CO_(2)Reduction显示文摘Electrochemical carbon dioxide reduction reaction(CO_(2)RR)involves a variety of intermediates with highly correlated reaction and ad-desorption energies,hindering optimization of the catalytic activity.For example,increasing the binding of the*COOH to the active site will generally increase the*CO desorption energy.Breaking this relationship may be expected to dramatically improve the intrinsic activity of CO_(2)RR,but remains an unsolved challenge.Herein,we addressed this conundrum by constructing a unique atomic dispersed hetero-pair consisting of Mo-Fe di-atoms anchored on N-doped carbon carrier.This system shows an unprecedented CO_(2)RR intrinsic activity with TOF of 3336 h−1,high selectivity toward CO production,Faradaic efficiency of 95.96%at−0.60 V and excellent stability.Theoretical calculations show that the Mo-Fe diatomic sites increased the*COOH intermediate adsorption energy by bridging adsorption of*COOH intermediates.At the same time,d-d orbital coupling in the Mo-Fe di-atom results in electron delocalization and facilitates desorption of*CO intermediates.Thus,the undesirable correlation between these steps is broken.This work provides a promising approach,specifically the use of di-atoms,for breaking unfavorable relationships based on understanding of the catalytic mechanisms at the atomic scale. | Zhaoyong Jin Meiqi Yang Yilong Dong Xingcheng Ma Ying Wang Jiandong Wu Jinchang Fan Dewen Wang Rongshen Xi Xiao Zhao Tianyi Xu Jingxiang Zhao Lei Zhang David J.Singh Weitao Zheng Xiaoqiang Cui | 2024 | Nano-Micro Letters2024，16，1： | 0 |
