| 1 | Effects of ion concentration and natural organic matter on arsenic(V) removal by nanofiltration under different transmembrane pressures显示文摘The removal of As(V) from synthetic water was studied using four different nanofiltration (NF) membranes (ESNA-1-K1, NF270, ESNA-1-LF, and HODRA-CORE). The influences of ion concentration, transmembrane pressure (TMP), and the presence of natural organic matter (humic acid, HA) on the arsenic removal efficiency and permeate flux were investigated. The arsenic rejection of ESNA- 1-LF was higher than those of the other membranes in all experiments (> 94%), and the HODRA-CORE membrane gave the lowest removal of arsenic (< 47%). An increase in the ion concentration in the feed solution and addition of HA decreased the arsenic rejection of the HODRA-CORE membrane. However, both increasing of the ion concentration and addition of HA made the rejection increased for the other membranes (ESNA-1-K1, NF270, and ESNA-1-LF). With increasing TMP, for all four NF membranes, increases in both arsenic rejection and permeate flux were observed. The permeate fluxes of the four NF membranes decreased to some extent after addition of HA to the solutions for operating time of 6 hr. | Yang Yu Changwei Zhao Yangui Wang Weihong Fan Zhaokun Luan | 2013 | Journal of Environmental Sciences2013，25，2： | 7 |
| 2 | Effects of calcination temperature on physicochemical property and activity of CuSO4/TiO2 ammonia-selective catalytic reduction catalysts显示文摘CuSO4/TiO2 catalysts with high catalytic activity and excellent resistant to SO2 and H2 O,were thought to be promising catalysts used in Selective catalytic reduction of nitrogen oxides by NH3.The performance of catalysts is largely affected by calcination temperature.Here,effects of calcination temperature on physicochemical property and catalytic activity of CuSO4/TiO2 catalysts were investigated in depth.Catalyst samples calcined at different temperatures were prepared first and then physicochemical properties of the catalyst were characterized by N2 adsorption-desorption,X-ray diffraction,thermogravimetric analysis,Raman spectra,Fourier-transform infrared spectroscopy,X-ray photoelectron spectroscopy,temperature-pro grammed desorption of NH3,temperature-programmed reduction of H2 and in situ diffuse reflectance infrared Fourier transform spectroscopy.Results revealed that high calcination temperature had three main effects on the catalyst.First,sintering and anatase transform into rutile with increase of calcination temperature,causing a decrement of specific surface area.Second,decomposition of CuSO4 under higher calcination temperature,resulting in disappears of Br(?)nsted acid sites(S-OH),which had an adverse effect on surface acidity.Third,CuO from the decomposition of CuSO4 changed surface reducibility of the catalyst and favored the process of NH3 oxidation to nitrogen oxides(NOx).Thus,catalytic activity of the catalyst calcined under high temperatures(≥600℃)decreased largely. | Yanke Yu Jiali Zhang Changwei Chen Chi He Jifa Miao Huirong Li Jinsheng Chen | 2020 | Journal of Environmental Sciences2020，32，5： | 6 |
| 3 | Effect of Short-term Forest Bathing in Urban Parks on Perceived Anxiety of Young-adults: A Pilot Study in Guiyang, Southwest China显示文摘Forest can be taken as a natural therapy to alleviate perceived anxiety of visitors. Given the geographical difference between urban and rural forest environments, little is known about the urban forest therapy effect of anxiety alleviation with reference to the rural forest. In this study, forty-three university students(aged from 19 to 23) were recruited as participants to visit the forest parks at urban and rural areas of Guiyang City on 21 and 23 December 2016. The forest experience was separated by four sceneries. Participants were asked to complete questionnaires by self-evaluating specific anxiety change from 12 questions with scores from 1 to 10 at both entrance and exit of the parks. The Wilcoxon signed-rank test and paired t-test were used to compare the change of anti-anxiety scores during forest bathing and between urban and rural forests, respectively. Results revealed that forest bathing in the urban park can alleviate the anxiety from financial state(P = 0.0028), exam-pass pressure(P = 0.0040) and love-affair relationship(P = 0.0286). Although rural forest bathing can also alleviate the anxiety from financial state(P = 0.0222), meanwhile, it maintained the anxiety about campus life(P < 0.0001). Forest tree richness tended to be higher in the rural forest park than in the urban one, which in contrast decreased the anxiety alleviation from inter-communication in the rural forest park(P = 0.0487). Principle component analysis indicated that participants tended to perceive more decline of anxiety from social contact in the urban forest. In conclusion, university students were recommended to pay a short visit to the urban forest with partners if they felt anxious about personal affairs and felt necessary to talk with others. For general people's visiting, urban forest trees can be controlled in diversity to some extent to look orderly and alleviate perceived anxiety. | ZHOU Changwei YAN Lingbin YU Lifei WEI Hongxu GUAN Haoming SHANG Chongfei CHEN Feiyu BAO Junzhou | 2019 | Chinese Geographical Science2019，29，1： | 5 |
| 4 | Preparation of SGO-modified nanofiltration membrane and its application in SO_4^(2-) and Cl^- separation in salt treatment显示文摘The lack of fresh water in the world makes the search for an effective method to decontaminate water an urgent priority.An important step is to remove different multivalent ions in salt treatment.Nanofiltration(NF)has been used for treating water containing different kinds of salts.In this work,sulfonate group-modified graphene oxide(SGO)was prepared,and added during the interfacial polymerization(IP)reaction to prepare SGO-modifiedNF membranes(PA-SGO).The chemical composition,structure and surface properties of PA and PA-SGO membranes were characterized by FT-IR,XPS,SEM,AFM,contact angle and zeta potential measurements.Their water flux,salt rejection and antifouling abilities were investigated systematically.The testing results showed that the water flux of PA-SGO(0.03%SGO)was 45.85 LMH under a pressure of 0.2 MPa,and the salt rejection varied in the order of Na_2SO_4(98.99%)>MgSO_4(91.25%)>MgCl_2(42.27%)>NaCl(21.96%).An anti-fouling experiment indicated that the PA-SGO membrane had good anti-fouling properties because of its decreased roughness and increased hydrophilicity and electronegativity.The PA-SGO membrane has good potential for use in removing salt ions from water. | Yanjun Zhang Changwei Zhao Shaofeng Zhang Ling Yu Jiding Li Li-an Hou | 2019 | Journal of Environmental Sciences2019，31，4： | 2 |

| 6 | Automatic Tongue Tracking in X-Ray Images显示文摘X-ray imaging is an effective technique to obtain the continuous motions of the vocal tract during speech, and Active appearance model(AAM) is a useful tool to analyze the X-ray images. However, for the task of tongue tracking in X-ray images, the accuracy of AAM fitting is insufficient. AAM aims to minimize the residual error between the model appearance and the input image. It often fails to accurately converge to the true landmarks. To improve the tracking accuracy, we propose a fitting method by combining Constrained local model(CLM) into AAM.In our method, we first combine the objective functions of AAM and CLM into a single objective function. Then,we pro ject out the texture variation and derive a gradient based method to optimize the objective function. Our method effectively incorporates not only the shape prior and global texture, but also local texture around each landmark. Experiments demonstrate that the proposed method significantly reduces the fitting error. We also show that realistic 3D tongue animation can be created by using tongue tracking results of the X-ray images. | LUO Changwei LI Rui YU Lingyun YU Jun WANG Zengfu | 2015 | Chinese Journal of Electronics2015，24，4： | 1 |

| 11 | Influence of incorporating beta zeolite nanoparticles on water permeability and ion selectivity of polyamide nanofiltration membranes显示文摘A novel polyamide(PA) thin film nanocomposite(TFN) membrane modified with Beta( β) zeolite was prepared by interfacial polymerization on a poly(ether sulfone)(PES) ultrafiltration membrane. Compared with the PA thin film composite(TFC) membrane, the introduction of β zeolite with porous structure notably increased the water flux of TFN membrane. Because the β zeolite with tiny-sized and well-defined inner-porous acted as prior flow channels for water molecules and a barrier for the sulfate ions. The successful introduction of β zeolite into the(PA) selective layer and their dispersion in the corresponding layer were verified by scanning electron microscope(SEM) and atomic force microscopy(AFM). Water contact angle, zeta potential measurements were used to characterize the changes of membrane surface properties before and after incorporating the β zeolite. With the β zeolite introducing, the water contact angle of modified TFN membrane was decreased to 47.8°, which was benefited to improve the water flux. Meanwhile, the negative charges of the modified TFN membrane was increased, resulting in an enhancement of separation effect on SO4^2- and Cl^-. In term of nanofiltration(NF) experiments, the highest pure water flux of the TFN membranes reached up to 81.22 L m^(-2) hr^-1 under operating pressure of 0.2 MPa, which was 2.5 times as much as the pristine TFC membrane. | Baoleerhu Borjigin lixue Liu Ling Yu Lili Xu Changwei Zhao Jun Wang | 2020 | Journal of Environmental Sciences2020，32，12： | 1 |

| 13 | Water-soluble brown carbon in atmospheric aerosols from the resource-dependent cities:Optical properties,chemical compositions and sources显示文摘As a vital type of light-absorbing aerosol,brown carbon(BrC)presents inherent associations with atmospheric photochemistry and climate change.However,the understanding of the chemical and optical properties of BrC is limited,especially in some resource-dependent cities with long heating periods in northwest China.This study showed that the annual average abundances of Water-soluble BrC(WS-BrC)were 9.33±7.42 and 8.69±6.29μg/m^(3)in Baotou and Wuhai and the concentrations,absorption coefficient(Abs_(365)),and mass absorption efficiency(MAE365)of WS-BrC presented significant seasonal patterns,with high values in the heating season and low values in the non-heating season;while showing opposite seasonal trends for the Absorption Angstr?m exponent(AAE_(300-400)).Comparatively,the levels of WS-BrC in developing regions(such as cities in Asia)were higher than those in developed regions(such as cities in Europe and Australia),indicating the significant differences in energy consumption in these regions.By combining fluorescence excitation-emission matrix(EEM)spectra with the parallel factor(PARAFAC)model,humic-like(C1 and C2)and proteinlike(C3)substances were identified,and accounted for 61.40%±4.66%and 38.6%±3.78%at Baotou,and 60.33%±6.29%and 39.67%±4.17%at Wuhai,respectively.The results of source apportionment suggested that the potential source regions of WS-BrC varied in heating vs.non-heating seasons and that the properties of WS-BrC significantly depended on primary emissions(e.g.,combustion emissions)and secondary formation. | Haoji Wang Yue Su Yangzheng Liu Fei Xie Xingjun Zhou Ruihong Yu Changwei Lü Jiang He | 2024 | Journal of Environmental Sciences2024，，4： | 0 |
| 14 | Endoscopic ultrasound-guided injection of carbon nanoparticles suspension to label rectal cancer before neoadjuvant chemoradiotherapy:a retrospective cohort study显示文摘Background:Localization of the primary tumor and ensuring safe distal surgical margins(DSMs)following neoadjuvant chemoradiotherapy(nCRT)are challenging in locally advanced rectal cancers(LARCs).This study investigated the effectiveness of carbon nanoparticles suspension(CNS)for labeling the primary tumor and allowing precise tumor resection after nCRT.Methods:Clinicopathological data of LARC patients who underwent nCRT followed by laparoscopic radical anal preservation surgery at our center between January 2018 and February 2023 were prospectively collected.The patients were divided into the CNS tattooed(CNS)and non-tattooed(control)groups.In the CNS group,CNS was injected in four quadrants on the anal side 1 cm away from the lower tumor margin.DSMs were determined through intraoperative distal rectal examination in the control group and observation of CNS tattoos in the CNS group.DSM lengths and positive DSM rates were compared between the two groups to analyse the feasibility and effectiveness of CNS for labeling LARCs before nCRT.Results:There was no statistically significant difference in the basic demographic data,effectiveness of nCRT,or post-operative recovery rates between the two groups(all P>0.05).In the CNS group,CNS tattoos were observed on the outside of the rectal wall,with an overall efficiency of 87.1%(27/31).The CNS group had fewer positive DSMs and safer DSM lengths(2.73±0.88 vs 2.12±1.15 cm,P=0.012)than the control group(P<0.05).Conclusions:Endoscopic ultrasound-guided injection of CNS tattoos before nCRT could effectively label the LARCs,ensuring safe DSMs during anus-preserving surgeries(Chictr.org.cn No.:ChiCTR2300068991). | Nan Lin Yuanzhao Wang Changwei Yu Weihang Wu Yongchao Fang Jin Yang Wangwu Liu Rong Wang Yanyan Jiang Yu Wang | 2023 | Gastroenterology Report2023，11，1： | 0 |
| 15 | Enhancement of T cell infiltration via tumor-targeted Th9 cell delivery improves the efficacy of antitumor immunotherapy of solid tumors显示文摘Insufficient infiltration of T cells severely compromises the antitumor efficacy of adoptive cell therapy(ACT)against solid tumors.Here,we present a facile immune cell surface engineering strategy aiming to substantially enhance the anti-tumor efficacy of Th9-mediated ACT by rapidly identifying tumor-specific binding ligands and improving the infiltration of infused cells into solid tumors.Non-genetic decoration of Th9 cells with tumor-targeting peptide screened from phage display not only allowed precise targeted ACT against highly heterogeneous solid tumors but also substantially enhanced infiltration of CD8+T cells,which led to improved antitumor outcomes.Mechanistically,infusion of Th9 cells modified with tumor-specific binding ligands facilitated the enhanced distribution of tumor-killing cells and remodeled the immunosuppressive microenvironment of solid tumors via IL-9 mediated immunomodulation.Overall,we presented a simple,cost-effective,and cell-friendly strategy to enhance the efficacy of ACT against solid tumors with the potential to complement the current ACT. | Tao Chen Yucheng Xue Shengdong Wang Jinwei Lu Hao Zhou Wenkan Zhang Zhiyi Zhou Binghao Li Yong Li Zenan Wang Changwei Li Yinwang Eloy Hangxiang Sun Yihang Shen Mohamed Diaty Diarra Chang Ge Xupeng Chai Haochen Mou Peng Lin Xiaohua Yu Zhaoming Ye | 2023 | Bioactive Materials2023，，5： | 0 |
| 16 | Arbitrary manipulations of focused higher-order Poincare beams by a Fresnel zone metasurface with alternate binary geometric and propagation phases显示文摘The manipulation of high-quality vector beams(VBs)with metasurfaces is an important topic and has potential for classical and quantum applications.In this paper,we propose a Fresnel zone(FZ)metasurface with metallic nanoslits arranged on FZs,which sets alternate binary geometric and propagation phases to cancel the incident spin component and focus the converted spin component(CSC).The rotation designs of nanoslits transform the incident polarization state on the conventional Poincare sphere to VBs on the higher-order Poincare(HOP)sphere.The two orbital angular momentum states of the CSCs were manipulated,and the focused HOP beams were generated.The experimental results demonstrate the broadband generation of arbitrarily focused HOP beams of high quality under the illumination of the red(632.8 nm),green(532 nm),and blue(473 nm)light.This work will be of significance for the applications of VBs in different areas,such as precision metrology,optical micromanipulation,and quantum information. | XIANGYU ZENG YUQIN ZHANG MANNA GU ZIJUN ZHAN RUIRUI ZHANG YU ZHANG RUI SUN CHANGWEI HE CHUNXIANG LIU CHUANFU CHENG | 2022 | Photonics Research2022，10，4： | 0 |

| 19 | All-in-one phototheranostics based on BTP-4F-DMO nanoparticles for NIR-II fluorescence/photoacoustic dual-mode imaging and combinational therapy显示文摘Various phototheranostics have recently been developed for phototherapy.Through proper molecular design,the photochemical and photophysical properties of these phototheranostics can be promoted.Herein,an acceptor-donor-acceptor(A-D-A)-structured dye,BTP-4F-DMO,was synthesized and prepared into water-soluble nanoparticles(NPs).The obtained BTP-4F-DMO NPs had strong absorption from650 nm to 850 nm and a fluorescence emission peak at~900 nm that tailed to~1100 nm.The NPs showed a superhigh photothermal conversion efficiency of 90.5%±5%and could simultaneously generate·OH and^(1)O_(2)with a^(1)O_(2)generation quantum yield of 4.6%under 808 nm laser irradiation.Due to these advanced properties,BTP-4F-DMO NPs can switch the role of autophagy from pro-survival to prodeath,thereby further promoting cancer cell death.These features make BTP-4F-DMO NPs a promising multifunctional phototheranostic agent for NIR-II fluorescence/photoacoustic dual-mode imaging-guided synergetic photodynamic/photothermal therapy.In general,this work provides a strategy for expanding the biomedical applications of organic A-D-A-structured phototheranostics. | Ke Yang Bowen Yu Wei Liu Zequn Zhang Li Huang Shaojing Zhao Benhua Wang Jianing Yi Jun Yuan Yingping Zou Changwei Lin Xiangzhi Song Minhuan Lan | 2023 | Chinese Chemical Letters2023，34，6： | 0 |
| 20 | Recent advances in the catalytic pyrolysis of biomass显示文摘Biomass is considered as a renewable and alternative resource for the production of fuels and chemicals,since it is the only carbon and hydrogen containing resource that we canfind in the world except for fossil resources,capable of being converted to hydro-carbons.The pyrolytic liquefaction of biomass is a promising way to convert biomass to useful products.This paper briefly surveys the present status of the direct catalytic pyrolysis for the liquefaction of biomass.The direct use of catalysts could decrease the pyrolysis temperature,increase the conversion of biomass and the yield of bio-oil,and change the distribution of the pyrolytic liquid products then improve the quality of the bio-oil obtained.The fact that biomass is in solid state present great challenges for its conversion and for the effective use of catalysts due to the bad heat transfer characteristics and bad mass transfer properties.These barriers appeal for the development of a new catalyst and new catalytic process as well as the integration of both.Process design and process intensification are of significant importance in the catalytic conversion of biomass. | Changwei HU Yu YANG Jia LUO Pan PAN Dongmei TONG Guiying LI | 2011 | Frontiers of Chemical Science and Engineering2011，5，2： | 0 |
