| 1 | Water regime-nitrogen fertilizer incorporation interaction:Field study on methane and nitrous oxide emissions from a rice agroecosystem in Harbin, China显示文摘Water regime and nitrogen(N) fertilizer are two important factors impacting greenhouse gases(GHG) emission from paddy field, whereas their effects have not been well studied in cold region. In this study, we conducted a two-year field experiment to study the impacts of water regime and N fertilizer on rice yields and GHG emissions in Harbin, China, a cold region located in high latitudes. Our results showed that intermittent irrigation significantly decreased methane(CH_4) emission compared with continuous flooding, however,the decrement was far lower than the global average level. The N_2O emissions were very small when flooded but peaked at the beginning of the disappearance of floodwater. The N fertilizer treatments increased CH_4 emissions at low level(75 kg N/ha). But both CH_4 and N_2O emissions were uninfluenced at the levels of 150 kg N/ha and 225 kg N/ha. Rice yields increased under intermittent irrigation and were highest at the level of 150 kg N/ha. From our results, we recommended that the intermittent irrigation and 150 kg N/ha as the ideal water regime-nitrogen fertilizer incorporation for this area to achieve low GHG emissions without impacting rice yields. | Wenjun Dong Jia Guo Lijun Xu Zhifeng Song Jun Zhang Ao Tang Xijuan Zhang Chunxu Leng Youhong Liu Lianmin Wang Lizhi Wang Yang Yu Zhongliang Yang Yilei Yu Ying Meng Yongcai Lai | 2018 | Journal of Environmental Sciences2018，30，2： | 12 |
| 2 | Preparation of Silver Nanowires via a Rapid,Scalable and Green Pathway显示文摘Rapid synthesis of silver nanowires(Ag NWs) with high quality and a broad processing window is challenging because of the low selectivity of the formation of multiply twinned particles at the nucleation stage for subsequent Ag NWs growth.Herein we report a systematic study of the water-involved heterogeneous nucleation of Ag NWs with high rate(less than 20 min) in a simple and scalable preparation method.Using glycerol as a reducing agent and a solvent with a high boiling point,the reaction is rapidly heated to 210 ℃ in air to synthesize Ag NWs with a very high yield in gram level.It is noted that the addition of a small dose of water plays a key role for obtaining highly pure Ag NWs in high yield,and the optimal water/glycerol ratio is0.25%.After investigating a series of forming factors including reaction temperature and dose of catalysts,the formation kinetics and mechanism of the Ag NWs are proposed.Compared to other preparation methods,our strategy is simple and reproducible.These Ag NWs show a strong Raman enhancement effect for organic molecules on their surface. | Cheng Yang Youhong Tang Zijin Su Zhexu Zhang Cheng Fang | 2015 | Journal of Materials Science & Technology2015，31，1： | 3 |
| 3 | AIEgens in cell-based multiplex fluorescence imaging显示文摘Fluorescence imaging is an important branch of bioimaging.It is non-invasive and provides superior spatial and temporal resolution during the real-time monitoring of biological samples of interest.Although the spatial resolution limit of optical microscopes is about 200 nm,due to the diffraction limit,with the application of super-resolution fluorescence microscopy technologies this limit has been pushed below 30 nm.This makes it feasible to visualize biological structures in subcellular levels and to monitor subcellular biological processes in real time.However,due to the complexity of the biological structure and components within cells,simultaneous staining and monitoring multiple intracellular components with different coloured fluorophores is often needed during multiplex imaging,to better understand biological processes.Aggregation-induced emission luminogens(AIEgen)and AIEgen based nanoparticles(NPs)have presented many advantages in fluorescence imaging,with strong potential for biological science and nano-medicine.Herein this review,we focus on the advantages of AIEgen and AIEgen NP in cell-based fluorescence imaging,and the latest advances of AIEgens in cell-based multiplex imaging are summarized and discussed.The future perspectives are proposed. | Yabin Zhou Jin Hua Ben Zhong Tang Youhong Tang | 2019 | Science China Chemistry2019，62，10： | 3 |

| 5 | Multiplexed imaging detection of live cell intracellular changes in early apoptosis with aggregation-induced emission fluorogens显示文摘Apoptosis is an important process for maintaining tissue homeostasis and eliminating abnormal cells in multicellular organisms.Abnormality in apoptosis often leads to severe diseases such as cancers. Better understanding of its mechanisms and processes is therefore important. Accompanying molecular biology events of apoptosis is a series of cellular morphology changes: nucleus condensation, cell shrinkage and rounding, cell surface blebbing, dynamic blebbing, apoptotic membrane protrusions and nucleus fragmentations and finally, the formation and release of apoptotic bodies. It is difficult to detect cellular changes in the early phase of apoptosis due to the subtle changes at this phase. In the current study, we induced apoptosis in He La cells with H2 O2 and used nuclear dye Hoechst 33258, mitochondria, lysosome and cytoplasmic protein specific aggregation-induced emission fluorogens(AIEgens), TPE-Ph-In, 2 M-DABS and BSPOTPE to successfully perform live cell multiplexed imaging to investigate early apoptosis cellular events. We showed the gradual dissipation of mitochondria membrane potential until it is nondetectable by TPE-Ph-In. Increased mitophagy detected by TPE-Ph-In and 2 M-DABS, condensed nucleus detected by Hoechst33258, increased permeability and/or reduced integrity of nuclear membrane, and increased intracellular vesicles detected by2 M-DABS are some of the early events of apoptosis. | Yabin Zhou Haixiang Liu Na Zhao Zhiming Wang Michael Z.Michael Ni Xie Ben Zhong Tang Youhong Tang | 2018 | Science China Chemistry2018，61，8： | 2 |

| 7 | AIEgen-enhanced protein imaging:Probe design and sensing mechanisms显示文摘Proteins are the building blocks of life,regarded as one of the most complex and crucial biomacromolecules in biological systems,and playing a significant role in executing genes and transferring genetic information.According to recent research,due to the structural intricacy of proteins and their sensitivity to physical and chemical degradation processes,they could be utilized as biomarkers or therapeutic agents in the diagnosis,treatment,or even prevention of different diseases.Therefore,modern pathways have been developed for understanding the function of proteins,resulting in intriguing approaches in the field of protein-related diseases.The diagnostic strategies to deal with such diseases,including protein analysis,protein quantification,and protein imaging,were argued in depth.Meanwhile,the aggregationinduced emission(AIE)concept and its potential applications for real-time imaging make AIE luminogens(AIEgen)attractive for protein imaging.In general,AIEgens refer to those luminogenic chemicals that are nonluminescent in solution,but luminescent in either the aggregated or solid states.This review is focused on the emergence of AIE materials in protein tracking,detecting,and imaging for medical applications. | Sanaz Naghibi Tong Chen Amin Jamshidi Ghahfarokhi Youhong Tang | 2021 | Aggregate2021，2，3： | 1 |
| 8 | Revisiting an ancient inorganic aggregation-induced emission system:An enlightenment to clusteroluminescence显示文摘Organic and inorganic clusteroluminescence have attracted great attention while the underlying mechanisms is still not well understood.Here,we employed a series of ancient inorganic complexes platinocyanides with aggregation-induced emission property to elucidate the mechanism of clusteroluminescence including how does the chromophore form and how does the solid structures influence the luminescence behaviors.The results indicate that the isolated platinocyanide cannot work as a chromophore to emit visible light,while their clusterization at aggregate state can trigger the d-orbitals coupling of the platinum atoms to facilitate the electron exchange and delocalization to form a new chromophore to emit visible light.Furthermore,the counter ions and H2O ligands help to rigidify the three-dimensional network structure of the platinocyanides to suppress the excited state nonradiative decay,resulting in the high quantum yield of up to 96%.This work fundamentally helps understanding both the organic and inorganic clusteroluminescence phenomenon. | Zheng Zhao Zaiyu Wang Javad Tavakoli Guogang Shan Jianyu Zhang Chen Peng Yu Xiong Xuepeng Zhang Tsz Shing Cheung Youhong Tang Bolong Huang Zhaoxun Yu Jacky W.Y.Lam Ben Zhong Tang | 2021 | Aggregate2021，2，2： | 1 |

| 14 | Visualizing light-induced dynamic structural transformations of Au clusters-based photocatalyst via in situ TEM显示文摘Ultrasmall gold(Au)clusters have been regarded as one of the prototypes materials for solar energy conversion due to their unique strong molecular-like light absorption properties.However,the light-induced aggregation of Au clusters into nanoparticles is one of the most important factors that restricts its application in photocatalysis.Although Au clusters aggregation has been widely demonstrated,the underlying mechanism for cluster fusion is still unclear due to the lack of experimental evidence.Herein,we report the direct observation of Au clusters on TiO_(2) nanosheets aggregating when used as visible light photocatalysts for the reduction of nitroaromatics.Through in situ high-resolution transmission electron microscopy(TEM),the coexistence of two fusion mechanisms of Au clusters on TiO_(2) under ultraviolet-visible(UV-Vis)light irradiation in air is identified,i.e.,the migration and coalescence(MC)and Ostwald ripening(OR).Additionally,the correlation between the photostability of Au clusters and reaction atmospheres has been investigated,among which Au clusters have higher stability in an inert N_(2) atmosphere or vacuum than the oxidizing atmospheres(i.e.,air and O_(2)).These results indicate the inherent stability of Au cluster during photocatalysis,and instability comes from the consuming of ligand layer.This work not only discloses the underlying mechanism of Au cluster sintering but also provides guidelines for enhancing metal clusters-based photocatalysts stability. | Bo Weng Youhong Jiang Hong-Gang Liao Maarten B.J.Roeffaers Feili Lai Haowei Huang Zichao Tang | 2021 | Nano Research2021，14，8： | 1 |

| 18 | On mechanical properties of nanocomposite hydrogels:Searching for superior properties显示文摘Nanocomposite hydrogels are the combination of known components that are a hydrogel and nanometre-sized fillers,typically leading to improved mechanical properties or new functionalities.With simplicity of design and ease of synthesis,recent advances have highlighted that this family of hydrogels holds the significant promise of application in diverse biomedical and engineering fields.The elaborate design and investigation as well as suitable application of nanocomposite hydrogels require the synergy of mechanics,materials science,engineering,and biology.Despite similarities in design and fabrication,the data of mechanical properties for nanocomposite hydrogels scatter in a large space.It is worthwhile comparing various nanocomposite hydrogels for similarities and differences in mechanical properties to aid in designing novel hydrogels with extreme properties,and guide practical applications.This review aims to fill,in the literature,the missing gap of addressing mechanical measurement methods and comparison of mechanical properties in this ever-evolving broad area of research.Finally,the challenges and future research opportunities are highlighted. | Wenjin Xing Youhong Tang | 2022 | Nano Materials Science2022，4，2： | 0 |
| 19 | Interactions between stearic acid and calcite surfaces:Experimental and computer simulation studies显示文摘Calcite surface was modified with stearic acids,and the interaction between them was investigated both experimentally and theoretically.Stearic-acid-modified calcite powders were investigated with Fourier transform infrared spectroscopy,X-ray diffraction,zeta potential analyser and contact angle measurement.Then,the density functional theory calculations were performed to explore the interaction at the atomic scale.The experi-mental results and simulation indicated that stearic acids interact with calcite surface via chelation between the double-bond O atom of-COOH and the Ca atom on calcite surface.The terminal methyl group of the stearic acids decreases the hydrophilicity of the calcite surface,and the interaction between different crystal faces of calcite is different. | Lihua Zhang Laibao Liu Xiaopeng Li Youhong Tang Chuanbei Liu Hong-Ping Zhang | 2021 | Biosurface and Biotribology2021，7，3： | 0 |
| 20 | Thin-film flow technology in controlling the organization of materials and their properties Special Collection:Distinguished Australian Researchers显示文摘Centrifugal and shear forces are produced when solids or liquids rotate.Rotary systems and devices that use these forces,such as dynamic thin-film flow technology,are evolving continuously,improve material structure-property relationships at the nanoscale,representing a rapidly thriving and expanding field of research high with green chemistry metrics,consolidated at the inception of science.The vortex fluidic device(VFD)provides many advantages over conventional batch processing,with fluidic waves causing high shear and producing large surface areas for micro-mixing as well as rapid mass and heat transfer,enabling reactions beyond diffusion control.Combining these abilities allows for a green and innovative approach to altering materials for various research and industry applications by controlling small-scale flows and regulating molecular and macromolecular chemical reactivity,self-organization phenomena,and the synthesis of novel materials.This review highlights the aptitude of the VFD as clean technology,with an increase in efficiency for a diversity of top-down,bottom-up,and novel material transformations which benefit from effective vortex-based processing to control material structure-property relationships. | Clarence Chuah Xuan Luo Javad Tavakoli Youhong Tang Colin L.Raston | 2024 | Aggregate2024，5，1： | 0 |
