| 2 | Visual dual chemodynamic/photothermal therapeutic nanoplatform based on superoxide dismutase plus Prussian blue显示文摘Enzyme-based anticancer therapy is more attractive for the less side effect than conventional chemotherapy.However,the poor stability and low membrane permeability of enzymes during the intracellular delivery are constraints for its practical applications.In this work,we synthesized novel near-infrared (NIR)-responsive core-shell-structured Prussian blue@fibrous SiO2 (PBFS) nanoparticles as the carrier of superoxide dismutase (SOD) and a glutathione (GSH)-activated Fenton reagent (DiFe).The PBFS nanoparticles are further modified with aGSH-responsive cationic polymer (poly(2-(acryloyloxy)-N,N-dimethyl-N-(4-(((2-((2-(((4-methyl-2-oxo-2H-chromen-7-yl)carbamoyl)oxy)ethyl)disulfaneyl)ethoxy)carbonyl)amino)benzyl)ethan-1-aminium,PSS) containing disulfide bonds and fluorophores.After SOD and DiFe are loaded on the PBFS-PSS nanoparticles,dual chemodynamic/photothermal therapeutic nanoparticulate systems (PBFS-PSS/DiFe/SOD) are obtained.In vitro experiments show that PBFS-PSS/DiFe/SOD nanoparticles have good biocompatibility and can be tracked under fluorescence microscope during the intracellular delivery process in MCF-7 tumor cells due to the GSH-activated release of fluorophores.They also exhibit high efficiency in NIR photothermal conversion and GSH-activated Fenton reaction in tumor cells,thus achieving high-efficient killing effect of tumor cells based on the combination of photothermal and chemodynamic therapeutic performance (PTT and CDT).This work offers a novel pathway to construct a visual multifunctional nanomedicine platform for future cancer therapy. | Shan Lei Jinxing Chen Kun Zeng Mozhen Wang Xuewu Ge | 2019 | Nano Research2019，12，5： | 2 |

| 4 | Preparation and adsorption property of novel inverse-opal hierarchical porous N-doped carbon microspheres显示文摘The design of pore structure is the key factor for the performance of porous carbon spheres.In this wo rk,novel micron-sized colloidal crystal microspheres consisting of fibrous silica(F-SiO_(2)) nanoparticles are firstly prepared by water-evapo ration-induced self-assembly of F-SiO_(2) nanoparticles in the droplets of an inverse emulsion system to be used as sacrificial templates.Acrylonitrile(AN) was infiltrated in the voids of the F-SiO_(2) colloidal crystal microspheres,and in-situ induced by ^(60)Co γ-ray to polymerize into polyacrylonitrile(PAN).After the PAN-infiltrated F-SiO_(2) colloidal crystal microspheres were carbonized and etched with HF solution,novel micron-sized inverse-opal N-doped carbon(IO-NC) microspheres consisting of hollow carbon nanoparticles with a hierarchical macro/meso-porous inner surface were obtained.The IO-NC microspheres have a specific surface area as high as 266.4 m^(2)/g and a molar ratio of C/N of 5.They have a good dispersibility in water,and show a high adsorption capacity towards rhodamine B(RhB) up to 137.28 mg/(g microsphe re).This work offers a way to obtain novel micron-sized hierarchical macro/meso-porous N-doped carbon microspheres,which opens a new idea to prepare high-performance hierarchical porous carbon materials. | Wenxiu Yang Guoqing Xu Jingjing Shu Mozhen Wang Xuewu Ge | 2021 | Chinese Chemical Letters2021，32，2： | 1 |

| 15 | Study on the morphological regulation mechanism of hollow silica microsphere prepared via emulsion droplet template显示文摘The morphology regulation of hollow silica microspheres is significant for their properties and applications. In this paper, hollow silica microspheres were formed through the hydrolysis and condensation reaction of tetraethyl orthosilicate(TEOS) at the interface of the emulsion droplet templates composed of liquid paraffin and TEOS, followed by dissolving paraffin with ethanol. The effects of various factors including the emulsifier structure and content, TEOS content, catalyst type, and the ethanol content in the continuous water phase on the particle size, shell thickness and morphology of the prepared hollow silica microspheres were studied in detail. The results show that the diffusion and contact of TEOS and water molecules as well as the hydrolysis condensation reaction of TEOS at the oil-water interface are two critical processes for the synthesis and morphological regulation of hollow silica microspheres. Cationic emulsifier with a hydrophobic chain of appropriate length is the prerequisite for the successful synthesis of hollow silica microspheres. The ethanol content in water phase is the dominant factor to determine the average diameter of hollow microspheres, which can vary from 96 nm to 660 nm with the increase of the volume ratio of alcohol-water from 0 to 0.7. The silica wall thickness varies with the content and the hydrophobic chain length of the emulsifier, TEOS content, and the activity of the catalyst. The component of the soft template will affect the morphology of the silica wall. When the liquid paraffin is replaced by cyclohexane, hollow microspheres with fibrous mesoporous silica wall are fabricated. This work not only enriches the basic theory of interfacial polymerization in the emulsion system, but also provides ideas and methods for expanding the morphology and application of hollow silica microspheres. | Chu Zhao Zhiqing Ge Zhuoni Jiang Shuo Yan Jingjing Shu Mozhen Wang Xuewu Ge | 2023 | Chinese Chemical Letters2023，34，4： | 0 |
| 16 | Centrifuge modelling of tunnelling below existing twin tunnels with different types of support显示文摘Tunnel excavation below existing tunnels produces ultimate and serviceability problems to the existing tunnels.The behaviours of induced stresses on the existing tunnels haven’t yet been fully recognized.In this study,a centrifuge model test was adopted to investigate the effects of new tunnelling on two existing overlying tunnels.One existing tunnel model simulated a prototype composite lining tunnel and the other simulated a prototype segmental lining tunnel.The volume loss produced by new tunnel excavation was modelled by an in-flight actuator system.The surface settlements,the existing tunnels settlements,the soil pressures on existing tunnels,the bending movements of existing tunnels,and the joint behaviours of existing tunnels were monitored.The volume of surface settlement trough was much smaller than the soil volume moving into the tunnel,due to the heave of the tunnel bottom and the dilation of sand during shearing.The maximum settlement of the segmental lining model was larger than that of the composite lining model as the equivalent bending stiffness of the composite lining model was larger than that of the former.Due to new tunnel excavation,the soil pressures on different positions of the existing tunnel behaved differently,and the bending movements of the existing tunnels decreased.Moreover,the joint deformation of existing tunnel caused by new tunnel excavation could be classified into three types:(1)translation,(2)rotation,and(3)combination of both. | Qian Fang Xiang Liu Kehan Zeng Xuedong Zhang Mozhen Zhou Jianming Du | 2022 | Underground Space2022，7，6： | 0 |
| 17 | Preparation and performance of novel magnetic phase-change-microcapsule-supported Bi_(2)WO_(6)catalyst显示文摘The design and synthesis of novel photocatalyst with self-temperature control function is an important topic in the field of advanced environmental functional materials.In this work,submicron-sized magnetic phase change microcapsules composed of paraffin core and Fe_(3)O_(4)-loaded silica shell are prepared,on which the Bi_(2)WO_(6)crystals is grown in situ through hydrothermal reaction to obtain novel magnetic phase-change-microcapsule-supported Bi_(2)WO_(6)catalyst(MP@FS/BWO).The MP@FS/BWO has a paraffin encapsulation ratio of 57.1%,and the phase change enthalpy of 105.1 J/g in a temperature range of 50–60℃,which endows the MP@FS/BWO with a certain self-temperature regulation ability.MP@FS/BWO shows excellent catalytic performance in the decomposition of rhodamine B under the simulated sunlight irradiation.After the light source is turned off,it still has good catalytic ability by maintaining high temperature due to its temperature control function based on the phase transition process.The MP@FS/BWO can be easily recycled by magnetic separation and shows good structural stability and reusability.This work provides a new idea for the development of long-effect and energy-saving outdoor photocatalysts. | Zhuoni Jiang Zhiqing Ge Shuo Yan Jingjing Shu Mozhen Wang Xuewu Ge | 2024 | Chinese Chemical Letters2024，35，3： | 0 |
| 18 | Flexible, high sensitive and radiation-resistant pressure-sensing hydrogel显示文摘Excellent radiation resistance is a prerequisite for pressure-sensitive hydrogels to be used in high-energy radiation environments. In this work, tannic acid-modified boron nitride nanosheet(BNNS-TA) is first prepared as the radiation-resistant additive by a facile one-step ball milling of hexagonal boron nitride and tannic acid. Then, polyacrylamide(PAAm)-based pressure-sensitive hydrogel doped with BNNS-TA and Fe^(3+)ions is fabricated. The ternary BNNS-TA/Fe^(3+)/PAAm hydrogel exhibits excellent compressive strength(at least four times the compressive strength of unfilled pure PAAm hydrogel), pressure-sensitive performance(gauge factor is up to 1.4), and performance recovery due to the combination of multiple intermolecular interactions, such as covalent crosslinking, hydrogen bonds, and ion coordination interactions.The BNNS-TA/Fe^(3+)/PAAm hydrogel can be made as a pressure sensor installed in the control circuit or attached on the human body to detect human activities accurately. More importantly, the compressive strength and the pressure-sensitive performance of the BNNS-TA/Fe^(3+)/PAAm hydrogel can be maintained after the hydrogel is irradiated by^(60)Co gamma-ray at an absorbed dose of 15 k Gy. As a comparison, the compressive strength of the unfilled PAAm hydrogel is only a quarter of that before irradiation. This work not only reveals a facile method to achieve the preparation of chemically modified BNNS as a promising radiation-resistant additive but also provides a novel strategy for the development of pressure-sensitive hydrogel devices in radiation environments. | Zhiwen Jiang Yusong Wang Guoqing Xu Zhuoni Jiang Zhiqing Ge Mozhen Wang Xuewu Ge | 2022 | Chinese Chemical Letters2022，33，2： | 0 |
| 19 | Self-assembly of graphene oxide nanosheets in t-butanol/water medium under gamma-ray radiation显示文摘The research on the properties of graphene oxide(GO) in various media has become one of the hottest topics since GO is now the main raw material for graphene-based advanced materials. In this work, the g-ray radiation chemistry effect of GO nanosheets and their self-aggregation behavior in t-butanol/water medium were investigated. The results show that GO nanosheets are reduced and hydroxyalkylated simultaneously by the alcohol free radicals produced by the radiolysis of t-butanol/water solution under g-ray radiation. The radiation-modified GO nanosheets will self-assemble into a self-standing graphene hydrogel when the p H of the solution is lower than 2. A hydroxyl-functionalized free-standing graphene aerogel is further obtained simply by freeze-drying. This work provides not only a general self-assembly mechanism of GO nanosheets in strong acidic alcohol/water media under high energy radiation, but also a facile and economical preparation method for hydroxyalkylated graphene-based aerogel. | Weikang Wang Yihu Wu Zhiwen Jiang Mozhen Wang Qichao Wu Xiao Zhou Xuewu Ge | 2018 | Chinese Chemical Letters2018，29，6： | 0 |
