1Adsorption and Desorption Behavior of Tannic Acid in Aqueous Solution on Polyaniline Adsorbent显示文摘Tannic acid is generally considered as one of polyphenolic pollutants, which may cause severe threats to the environment. In this study, polyaniline adsorbent was synthesized by chemical oxidation to remove tannic acid in aqueous solutions. The adsorption amount of tannic acid varied greatly with pH of solution and strong adsorption was at pH 5.8-6.7. Coexisting cations, such as Na+, K+, and Ca2+, can enhance the adsorption of tannic acid on poly-aniline, which may be contributed to the electrostatic interaction between tannic acid and polyaniline. The adsorp-tion process could be well described by Langmuir model and the maximum adsorption capacity was 117.65 mg·g-1 at 35 ℃ and pH 6.0. The thermodynamic parameters calculated from the adsorption isotherms indicate that the ad-sorption of tannic acid is spontaneous and endothermic process. The polyaniline saturated with tannic acid can be desorbed in alkaline solution and regenerated adsorbent can be used repeatedly with high adsorption capacity, which implies that polyaniline adsorbents have a great potential in water purification for the removal of tannic acid.WANG Jiahong JI Yan fen DING Shaolan MA Hongrui HAN Xiaojing 2013Chinese Journal of Chemical Engineering2013,21,6:7
2Mineral photoelectrons and their implications for the origin and early evolution of life on Earth显示文摘Energy is the key issue of all life activities.The energy source and energy yielding pathway are the key scientific issues of the origin and early evolution of life on Earth.Current researches indicate that the utilization of solar energy in large scale by life was an important breaking point of the early evolution of life on Earth and afterwards life gradually developed and flourished.However,in the widespread biochemical electron transfer of life activities,it is still not clear whether the electron source is sun or how electrons originated from sun.For billions of years,the ubiquitous semiconducting minerals in epigeosphere absorb solar energy,forming photoelectrons and photoholes.In reductive and weak acidic environment of early Earth,when photoholes were easily scavenged by reducing matters,photoelectrons were separated.Photoelectrons could effectively reduce carbon dioxide to organic matters,possibly providing organic matter foundation for the origin of life.Photoelectrons participated in photoelectron transfer chains driven by potential difference and transfer into primitive cells to maintain metabolisms.Semiconducting minerals,by absorbing ultraviolet,also protected primitive cells from being damaged by ultraviolet in the origin of life.Due to the continuous photoelectrons generation in semiconducting minerals and utilization by primitive cells,photoelectrons from semiconducting minerals’photocatalysis played multiple roles in the origin of life on early Earth,such as organic synthesis,cell protection,and energy supply.This mechanism still plays important roles in modern Earth surface systems.LU AnHuai WANG Xin LI Yan DING HongRui WANG ChangQiu ZENG CuiPing HAO RuiXia YANG XiaoXue 2014Science China Earth Sciences2014,57,5:5
3Photoelectrochemical performance of birnessite films and photoelectrocatalytic activity toward oxidation of phenol显示文摘Birnessite films on fluorine-doped tin oxide(FTO) coated glass were prepared by cathodic reduction of aqueous KMnO_4. The deposited birnessite films were characterized with X-ray diffraction, Raman spectroscopy, scanning electron microscopy and atomic force microscopy.The photoelectrochemical activity of birnessite films was investigated and a remarkable photocurrent in response to visible light was observed in the presence of phenol, resulting from localized manganese d–d transitions. Based on this result, the photoelectrocatalytic oxidation of phenol was investigated. Compared with phenol degradation by the electrochemical oxidation process or photocatalysis separately, a synergetic photoelectrocatalytic degradation effect was observed in the presence of the birnessite film coated FTO electrode.Photoelectrocatalytic degradation ratios were influenced by film thickness and initial phenol concentrations. Phenol degradation with the thinnest birnessite film and initial phenol concentration of 10 mg/L showed the highest efficiency of 91.4% after 8 hr. Meanwhile, the kinetics of phenol removal was fit well by the pseudofirst-order kinetic model.Huiqin Zhang Hongrui Ding Xin Wang Cuiping Zeng Anhuai Lu Yan Li Changqiu Wang 2017Journal of Environmental Sciences2017,29,2:3
4Semiconducting Mineral Photocatalytic Regeneration of Fe^(2+) Promotes Carbon Dioxide Acquisition by Acidithiobacillus ferrooxidans显示文摘Chemoautotrophic organisms have once been excluded from the development of universally applicable CO2 fixation technology due to its low production yields of biomass. In this study, we used Acidithiobacillus ferrooxidans (A.f.) as a model chemoautotrophic microorganism to test the hypothesis that exogenetic photoelectrons from semiconducting mineral photocatalysis can enable the regeneration of Fe2+ that could be then used by A.f. and support its growth. In a simulated electrochemical system, where exogenetic electrons were provided by an electrochemical approach, an accelerated growth rate of A.f. was observed as compared with that in traditional batch cultivation. In a coupled system, where light-irradiated natural rutile provided the primary electron source to feed A.f., the bacterial growth rate as well as the subsequent CO2 fixation rate was demonstrated to be in a light-dependent manner. The sustaining flow of photogenerated electrons from semiconducting mineral to bacteria provided an inexhaustible electron source for chemoautotrophic bacteria growth and CO2 fixation. This finding might contribute to the development of novel effective CO2 fixation technology.LI Yan LU Anhuai WANG Xin DING Hongrui WANG Changqiu 2013Acta Geologica Sinica(English Edition)2013,87,3:2

11Mimicking natural paragenetic semiconducting minerals MoS2/sphalerite:A simple method to fabricate visible-light photocatalyst显示文摘Natural paragenetic semiconducting minerals give important hints for fabricating stable and effective photocatalysts, which can be widely used in solar energy harvest and pollution control. To enhance the photoactivity of natural sphalerite(ZnS), needle-like nanocrystal MoS_2 was loaded on sphalerite surface through a hydrothermal method, mimicking the intergrowth of molybdenite(MoS_2) and sphalerite in nature. The resultant coupled MoS_2/sphalerite exhibited a hydrogen evolution reaction(HER) potential at-0.35 V(vs. NHE), and showed obvious photoresponse under visible-light. The photodegradation rate of methyl orange(MO) over MoS_2/sphalerite could reach 75% within 180 min. Compared to sphalerite, coupled MoS_2/sphalerite had a higher photocurrent,more positive HER potential and 66% higher photodegradation rate. The enhanced photoactivity was attributed to the charge transfer from sphalerite to MoS_2 and high electrons' mobility on MoS_2 layer.LIU Yi LI Yan LU AnHuai WANG ChangQiu DING HongRui 2017Science China(Technological Sciences)2017,60,12:0
12Microbe-Mediated Mineral Transformation of Montmorillonite by a Strain of Bacillus Mucilaginosus 3027显示文摘Clay minerals are ubiquitous on epigeosphere, especially in soils and sediments where microbes thrive. The clay-microbe interactions are common in these geological media and greatly contribute to accelerating the mineral transformation process, e.g. the illitization of nontronite (a Fe-rich smectite) catalyzed by microbes under anoxic atmosphere in 2 weeks. However, few has considered montmorillonite, a Fe-poor smectite more typical in natural environments than nontronite. This study therefore focuses on the interaction between montmorillonite and bacteria under conditions relevant to those in natural soils and sediments.YANG Xiaoxue LU Anhuai LI Yan WANG Haoran ZHU Yun DING Hongrui 2013矿物学报2013,33,S1:0
13Analysis of aortic wall stress and morphology in patients with type B aortic dissection显示文摘Risk assessment is critical in preventing aortic dissection(AD).This study aims to evaluate the wall stress(WS)distribution,especially at the locations of proximal tears in patient-specific type-B aortic dissection(TBAD)to explore the pathogenesis of dissection.In addition,the shape of the aortas were assessed and associated with TBAD risk.In this paper,30 three-dimensional models were reconstructed based on patient-specific CT angiography images,and finite element analysis(FEA)was used to analyze the admission blood pressure.In addition,the anatomic variables including the head vessel angles,the aorta diameters,curvatures and torturosity ware measured.Tears occurred at either local high WS or low WS region,and these acute TBAD patients can be classified into three groups based on the location of initial intimal tears.In addition,the WS values at tear sites of each group showed significant difference(P<0.001).Moreover,the angles of the left subclavian and brachiocephalic arteries were statistical different among three groups.Increased wall stress or decreased wall strength both contribute to the pathogenesis of aortic dissections.In addition,abnormal head vessel angles may be monitored as an important risk factor for aortic dissection,and its specific features may further help to determine the potential tear location.Hongrui Hu Zhan Liu Guoxin Chen Ding Yuan Tinghui Zheng 2021Medicine in Novel Technology and Devices2021,,3:0
14Design and mechanical properties testing of a new cross-helical popliteal artery stent显示文摘The popliteal artery has complex deformations such as axial shortening,bending,squeezing and twisting,as well as specific positions across the knee joint.Up to now there is a high incidence of in-stent restenosis(ISR)after the stent treatment of the popliteal artery.This paper aimed to design a new type of popliteal artery stent–crosshelical stent.to meet its deformation characteristics.The finite element analysis(FEA)method was used to test the mechanical properties of six stents with different winding height ratios of axial shortening,bending,plate extrusion,and torsional deformation.The results showed that the stents performance was affected by the ratio of winding height,the larger the winding height ratio,the worse the compliance,the worse the axial compressibility,but the better the radial support.And when the stent is torsional,the greater the winding height ratio is,the greater the stress is.In additon,the maximum stress was also related to the direction of torsion deformation,and the stress when the helix has the same direction with the torsion direction of the stent are was greater than that when the helix direction and torsion direction are opposite.Moreover,when the winding height ratio is 3:5,the performance of the stent is better,not only has better flexibility,its radial force,axial compression,and torsional deformation are better.It is concluded that the new cross-helical stent can adapt to the special deformation of popliteal artery and has good mechanical properties.Yuanxing Dai Hongrui Hu Jiarong Wang Ding Yuan Tinghui Zheng 2021Medicine in Novel Technology and Devices2021,,3:0
15Is polydopamine beneficial for cells on the modified surface?显示文摘Since the pioneering work of Messersmith’s group discovering that polydopamine(PDA)can serve to adhere to many types of materials,the PDA coating has,as a biomimetic approach,been widely used to enhance cell adhesion by surface modification to bind biologically active substances to a bioinert substrate.Nevertheless,it is unclear whether or not the PDA itself is beneficial for cells.Herein,we report that a PDA coating decreases viability of cells under normal culture and observation conditions.Such an inhibition effect was not caused by the free PDA or any inherent cytotoxicity of this chemical substance but a contactdependent phenomenon.Human bone marrow mesenchymal stem cells were employed as the default cell type and tissue culture plates were used as the default substrate,although some other cell types and substrates were also examined to confirm the universality of such an‘abnormal’phenomenon of a superstar molecule.The viability of cells on the PDA coating exhibited time dependence,and the decreased cell viability during the normal observation time was found to come from the decrease of cell number instead of the decrease of average viability per cell.The PDA coating led to less cell global migration yet more local motility of cells.Based on the concept of‘background adhesion’of cells on a surface without significant motifs of specific cell adhesion,we supposed that cells adhered to the PDA coating better,which influenced mobility and eventually proliferation.Hence,the cell behaviors on the PDA coating are reasonable,albeit a bit complicated.Yue Yu Xiuli Wang Yi Zhu Yingning He Hongrui Xue Jiandong Ding 2022Regenerative Biomaterials2022,9,1:0
16Ecological compensation mechanism for urban green land and its application in Shanghai, China显示文摘Urban green land compensation plays an impor-tant role in county development,ecological environment management and many other fields.The concept,methods and principles of urban green land are introduced in this paper.According to the pay fee method,the value and ecological function of various types of urban green land were analyzed.The cost-benefit analysis method(CBAM)was used to estimate different external diseconomy benefits caused by green land loss.The authors applied CBAM to estimate such benefits in the case of Shanghai,China,and calculated the actual compensation value for green land.Results indicated that in 2002,the compensation value for the green land of Shanghai was RMB 8.58×10^(5) Yuan/hm^(2).WANG Yan DING Xiaowen QIAN Longxia WANG Hongrui 2007Frontiers of Environmental Science & Engineering2007,1,3:0
17Maternal-derived antibodies hinder the antibody response to H9N2 AIV inactivated vaccine in the field显示文摘The H9N2 subtype avian influenza virus(AIV)inactivated vaccine has been used extensively in poultry farms,but it often fails to stimulate a sufficiently high immune response in poultry in the field,although it works well in laboratory experiments;hence,the virus still causes economic damage every year and poses a potential threat to public health.Based on surveillance data collected in the field,we found that broilers with high levels of maternal-derived antibodies(MDAs)against H9N2 virus did not produce high levels of antibodies after vaccination with a commercial H9N2 inactivated vaccine.In contrast,specific pathogen-free(SPF)chickens without MDAs responded efficiently to that vaccination.When MDAs were mimicked by administering passively transferred antibodies(PTAs)into SPF chickens in the laboratory,similar results were observed:H9N2-specific PTAs inhibited humoral immunity against the H9N2 inactivated vaccine,suggesting that H9N2-specific MDAs might hinder the generation of antibodies when H9N2 inactivated vaccine was used.After challenge with homologous H9N2 virus,the virus was detected in oropharyngeal swabs of the vaccinated and unvaccinated chickens with PTAs but not in the vaccinated chickens without PTAs,indicating that H9N2-specific MDAs were indeed one of the reasons for H9N2 inactivated vaccine failure in the field.When different titers of PTAs were used to mimic MDAs in SPF chickens,high(HI=12 log2)and medium(HI=log 9 log2)titers of PTAs reduced the generation of H9N2-specific antibodies after the first vaccination,but a booster dose would induce a high and faster humoral immune response even of PTA interference.This study strongly suggested that high or medium titers of MDAs might explain H9N2 inactivated vaccine failure in the field.Xue Pan Xin Su Pingyun Ding Jinhua Zhao Hongrui Cui Dawei Yan Qiaoyang Teng Xuesong Li Nancy Beerens Haitao Zhang Qinfang Liu Mart C.M.de Jong Zejun Li 2022Animal Diseases2022,2,2:0
18Homojunction and ohmic contact coexisting carbon nitride for efficient photocatalytic hydrogen evolution显示文摘Carbon nitride(CN)has attracted intensive attention as a visible light photocatalyst,but the rapid recombination of photogenerated charge carriers limits its photocatalytic activity.Herein,we develop a new strategy to construct both homojunction and ohmic junction into CN via selectively introducing metallized CN(MCN),which leads to rapid separation and transfer of photogenerated charge carriers.The polymerization of urea in the presence of KOH creates CN homojunction with amino and cyano groups.The subsequent molten salt treatment induces a new type of cyano-terminated CN that can be converted to MCN through photodoping,forming homojunction and ohmic contact coexisting CN(HOCN).The formed HOCN photocatalyst exhibits a high photocatalytic H_(2)evolution rate of 18.5 mmol·g^(-1)·h^(-1)under visible light irradiation,45-fold higher than that of bulk CN.This strategy provides a new idea for designing ohmic contact between semiconductor and metal,and realizing efficient photocatalysis by improving charge separation and transfer.Xiao Fang Lu Chen Hongrui Cheng Xiaoqiong Bian Wenhao Sun Kaining Ding Xinghe Xia Xin Chen Jiefang Zhu Yuanhui Zheng 2023Nano Research2023,16,7:0
19Reduction,mineralization,and magnetic removal of chromium from soil by using a natural mineral composite显示文摘Reductive immobilization has been a commonly used technique to detoxify Cr(VI)from soil;however,it's challenging to remove the reduced Cr from soil to prevent its re-oxidation.This work explored a natural magnetic composite for the remediation,mineralization,and magnetic removal of Cr(VI)from the soil.It consists of 77%magnetite and 23%pyrrhotite with strong magnetic properties.A series of characterization tests show that composites of magnetite and pyrrhotite are interlaced and closely bonded,and contain no other heavy metals.The Cr(VI)removal rate increases with the decrease in composite particle size.A kinetics study shows that removing Cr(VI)by the composite is likely through both adsorption and reduction.Acidic conditions are more favorable for the immobilization of Cr(VI),at 45.8 mg Cr(VI)removal per g of composite at pH 2.After 100 days of in-situ treatment by the composite,the leaching concentration(TCLP)of Cr(VI)-contaminated soil was 1.95 mg L^(-1),which was below the EPA limit(5 mg L^(-1))for hazardous waste.After reduction,the composite was separated from soil by magnetic characteristics,and 58.2%of Cr was found mineralized.The post-treatment Cr-containing composite was analyzed by SEM-EDS,Raman spectra,and XPS.It was found that Cr was mineralized on the surface of the composite in the form of Cr(OH)3,Cr_(2)O_(3),and FeCr_(2)O_(4).This indicates that reduction and mineralization of Cr(VI)in the soil can be accomplished through natural magnetic mineral composites and easily separated and removed from the soil,achieving a complete soil cleanup.Xiang Ji Chuanye Zhou Liangxi Chen Yanzhang Li Tianci Hua Yan Li Changqiu Wang Song Jin Hongrui Ding Anhuai Lu 2022Environmental Science and Ecotechnology2022,,3:0
