| 1 | Study on stabilities and electrochemical behavior of V(V) electrolyte with acid additives for vanadium redox flow battery显示文摘Several acid compounds have been employed as additives of the V(V) electrolyte for vanadium redox flow battery(VRB) to improve its stability and electrochemical activity. Stability of the V(V) electrolyte with and without additives was investigated with ex-situ heating/cooling treatment at a wide temperature range of-5 ?C to 60 ?C. It was observed that methanesulfonic acid, boric acid, hydrochloric acid, trifluoroacetic acid,polyacrylic acid, oxalic acid, methacrylic acid and phosphotungstic acid could improve the stability of the V(V) electrolyte at a certain range of temperature. Their electrochemical behaviors in the V(V) electrolyte were further studied by cyclic voltammetry(CV), steady state polarization and electrochemical impedance spectroscopy(EIS). The results showed that the electrochemical activity, including the reversibility of electrode reaction, the diffusivity of V(V) species, the polarization resistance and the flexibility of charge transfer for the V(V) electrolyte with these additives were all improved compared with the pristine solution. | Gang Wang Jinwei Chen Xueqin Wang Jing Tian Hong Kang Xuejing Zhu Yu Zhang Xiaojiang Liu Ruilin Wang | 2014 | Journal of Energy Chemistry2014，23，1： | 10 |

| 3 | Temperature-sensitive polymeric nanogels encapsulating withβ-cyclodextrin and ICG complex for high-resolution deep-tissue ultrasound-switchable fluorescence imaging显示文摘One of the thorny problems currently impeding the applications of the fluorescence imaging technique is the poor spatial resolution in deep tissue.Ultrasound-switchable fluorescence(USF)imaging is a novel imaging tool that has recently been explored to possibly surmount the above-mentioned bottleneck.Herein,αβ-cyclodextrin/indocyanine green(ICG)complex-encapsulated poly(N-isopropylacrylamide)(PNIPAM)nanogel was synthesized and studied for ex vivo/in vivo deep tissue/high-resolution near infrared USF(NIR-USF)imaging.To be specific,our results revealed that the average diameter of the as-prepared nanogels was significantly decreased to-32 nm from-335 nm compared to the reported ICG-PNIPAM nanoparticles.Additionally,the excitation/emission characteristics of the ICG itself in present nanogels were almost completely retained,and the resultant nanogel exhibited high physiological stability and positive biocompatibility.In particular,the signal-to-noise ratio of the USF image for the PNIPAM/P-cyclodextrin/ICG nanogel(33.01±2.42 dB)was prominently higher than that of the ICG-PNIPAM nanoparticles(18.73±0.33 dB)in 1.5-cm-thick chicken breast tissues.The NIR-USF imaging in 3.5-cm-thick chicken breast tissues was achieved using this new probe.The e x v iv o NIR-USF imaging of the mouse liver was also successfully obtained.Animal experiments showed that the present nanogels were able to be effectively accumulated into U87 tumor-bearing mice via enhanced permeability and retention effects,and the high-resolution NIR-USF imaging of in v ivo tumor was efficiently acquired.The metabolism and in vivo biodistribution of the nanogels were evaluated.Overall,the results suggest that the current nanogel is a highly promising NIR-USF probe for deep tissue and high-resolution USF imaging. | Ruilin Liu Tingfeng Yao Yang Liu Shuai Yu Liqin Ren Yi Hong Kytai T.Nguyen Baohong Yuan | 2020 | Nano Research2020，13，4： | 1 |
| 4 | In-situ hydrothermal synthesized γ-Al_2O_3/O-g-C_3N_4 heterojunctions with enhanced visible-light photocatalytic activity in water splitting for hydrogen显示文摘In this work,γ-Al_2O_3 and hydrogen peroxide treated g-C_3N_4(O-g-C_3N_4) were combined through a novel in-situ hydrothermal method to form heterojunction structured photocatalysts.These photocatalysts were characterized by X-ray diffraction(XRD),scanning electron microscopy(SEM),Fourier transform infrared spectroscopy(FT-IR),X-ray photoelectron spectroscopy(XPS),UV–vis diffuse reflectance spectroscopy and photoluminescence spectroscopy(PL).FT-IR results indicate that oxygen functional groups can be grafted on the surface of O-g-C_3N_4 by hydrogen peroxide treatment.The visible light photocatalytic hydrogen evolution rate was investigated in 10 vol% TEOA aqueous solution.The optimal Al_2O_3 mass content is set to be 20 wt% and the corresponding hydrogen evolution rate is 1288 μmol/h/g which is approximately 6,3 folds that of pristine g-C_3N_4 and O-g-C_3N_4 respectively and 1.6 folds that of mechanical mixed composite with the same Al_2O_3 mass content.The photocurrent density–time curves were carried out under visible light illumination for four on–off cycles.The electrochemical impedance spectroscopy(EIS) measurements verified the enhanced separation efficiency of electron–hole pairs.This work raised a new method to form the heterojunction structured photocatalysts and achieved a remarkable improvement of the photocatalytic activity in water splitting for hydrogen under visible light irradiation. | Yu Wang Yaping Zeng Boqiao Li Anqi Li Ping Yang Liu Yang Gang Wang Jinwei Chen Ruilin Wang | 2016 | Journal of Energy Chemistry2016，25，4： | 1 |
| 5 | Longitudinal virological changes and underlying pathogenesis in hospitalized COVID-19 patients in Guangzhou,China显示文摘Prolonged viral RNA shedding and recurrence of severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)in coronavirus disease 2019(COVID-19)patients have been reported.However,the clinical outcome and pathogenesis remain unclear.In this study,we recruited 43 laboratory-confirmed COVID-19 patients.We found that prolonged viral RNA shedding or recurrence mainly occurred in severe/critical patients(P<0.05).The average viral shedding time in severe/critical patients was more than 50 days,and up to 100 days in some patients,after symptom onset.However,chest computed tomography gradually improved and complete absorption occurred when SARS-CoV-2 RT-PCR was still positive,but specific antibodies appeared.Furthermore,the viral shedding time significantly decreased when the A1,430G or C12,473T mutation occurred(P<0.01 and FDR<0.01)and increased when G227A occurred(P<0.05 and FDR<0.05).High IL1R1,IL1R2,and TNFRSF21 expression in the host positively correlated with viral shedding time(P<0.05 and false discovery rate<0.05).Prolonged viral RNA shedding often occurs but may not increase disease damage.Prolonged viral RNA shedding is associated with viral mutations and host factors. | Zhengtu Li Yinhu Li Ruilin Sun Shaoqiang Li Lingdan Chen Yangqing Zhan Mingzhou Xie Jiasheng Yang Yanqun Wang Airu Zhu Guoping Gu Le Yu Shuaicheng Li Tingting Liu Zhaoming Chen Wenhua Jian Qian Jiang Xiaofen Su Weili Gu Liyan Chen Jing Cheng Jincun Zhao Wenju Lu Jinping Zheng Shiyue Li Nanshan Zhong Feng Ye | 2021 | Science China(Life Sciences)2021，64，12： | 1 |

| 15 | Interfacial ion regulation on 2D layered double hydroxide nanosheets for enhanced thermal insulation显示文摘Exploring new strategies to broaden the upper/lower limit of thermal conductivity is of great interest to develop thermal management materials that can adapt to extreme environments.In this work,we employ an interfacial ion regulation to enhance the thermal insulation performance of 2D layered double hydroxide nanosheets.The introduction of interfacial ion enlarges the interplanar spacing of Co(OH)_(2) nanosheets from 4.64 to 8.05 ?,which reduces phonon scattering length perpendicular to the two-dimensional plane and leads to enhanced interlayer thermal insulation.The interfacial ion-regulated Co(OH)_(2)(named as Co(OH)_(2)-M^(x-)) exhibits 3-fold enhancement of thermal insulation through decreasing the thermal conductivity to as low as 0.15 W m^(-1) K^(-1),which is among the top values in 2D solid materials.We anticipate that interfacial ion regulation for 2D nanosheets paves a new avenue to break through the thermal insulation limit. | Chun Wang Hengyu Xu Han Cheng Hao Yu Si Liu Wenjie Wang Ruilin Yuan Hongfei Liu Tianpei Zhou Wangsheng Chu HengAn Wu Yi Xie Changzheng Wu | 2022 | Science China Chemistry2022，65，5： | 0 |

| 18 | Synthesis and optical properties of LiNd(PO_3)_4 nanocrystals dispersion in DMSO/TBE显示文摘Lanthanide doped nanocrystals with strong fluorescence, long lifetime at high doping concentrations have great potential application in bio-imaging and liquid gain medium. LiNd(PO_3)_4(LNP) crystal was reported to be one of the most excellent laser crystals with high Nd3+ concentration, and their nanocrystals synthesized via improved combustion method for the first time had strong emission intensity and long fluorescence lifetime of 122 μs. Besides,LiNd(PO_3)_4 nanocrystals can be dispersed in mixed solvents of DMSO/TBE(CHBr2 CHBr2) to form a transparent colloidal dispersion, and Judd-Ofelt theory was used to evaluate their optical parameters. In summary, LiNd(PO_3)_4 nanocrystals possess long lifetime(116 μs), low solvents quenching rate(4.9%), large emission cross section(7.63 × 10^(-20) cm^2) and high quantum yield(35.2%) under high Nd3+ ions concentration(1×10^(20) cm^(-3)), which would be the most competitive colloidal gain medium of optical amplification and laser with LD pump and potential biomaterial with low particles concentration. | Zhongyue Wang Zhen Yang Ruilin Zheng Kehan Yu Peng Lv Chunxiao Liu Wei Wei | 2019 | Journal of Rare Earths2019，37，6： | 0 |
| 19 | Real-Time Generation of Reflections in the Optimized Image Space显示文摘This paper proposes a novel imagebased method to generate real-time reflections.Our algorithm aims to solve the problem of missing reflections in previous screen space based methods efficiently.Instead of computing reflections in the image space decided by the curren t eye position,our met hod conducts mos t of the reflection calculations in a new image space,which is determined by a carefully chosen camera position at run・time.The major criteria used to choose this optimized camera position is to make its corresponding image space contain as much as possible scene information to generate reflections.Our experimental results indicate that most of the missing reflections problems can be fixed by moving the reflection computations to this new image space.We also prove that the performance gains achieved by execu ting computations in the new image space can cancel out most of the overhead to generate it. | ZHANG Yanci YU Hanyou XIE Ruilin MENG Xiaoyou REN Wenjie XIE Kaili LIU Yanli | 2020 | Chinese Journal of Electronics2020，29，5： | 0 |
| 20 | Achieving macroscale superlubricity with ultra-short running-in period by using polyethylene glycol-tannic acid complex green lubricant显示文摘Superlubricating materials can greatly reduce the energy consumed and economic losses by unnecessary friction.However,a long pre-running-in period is indispensable for achieving superlubricity;this leads to severe wear on the surface of friction pairs and has become one of the important factors in the wear of superlubricating materials.In this study,a polyethylene glycol-tannic acid complex green liquid lubricant(PEG10000-TA)was designed to achieve macroscale superlubricity with an ultrashort running-in period of 9 s under a contact pressure of up to 410 MPa,and the wear rate was only 1.19×10^(–8)mm^(3)·N^(−1)·m^(−1).This is the shortest running-in time required to achieve superlubricity in Si_(3)N_(4)/glass(SiO_(2)).The results show that the strong hydrogen bonds between PEG and TA molecules can significantly reduce the time required for the tribochemical reaction,allowing the lubricating material to reach the state of superlubrication rapidly.Furthermore,the strong hydrogen bond can share a large load while fixing free water molecules in the contact zone to reduce shear interaction.These findings will help advance the use of liquid superlubricity technology in industrial and biomedical. | Changhe DU Tongtong YU Zishuai WU Liqiang ZHANG Ruilin SHEN Xiaojuan LI Min FENG Yange FENG Daoai WANG | 2023 | Friction2023，11，5： | 0 |
