| 1 | A review of recent advances in selective catalytic NO_x reduction reactor technologies显示文摘Research on NO_x treatment is extensive in recent years due to growing environmental awareness.Selective catalytic reduction(SCR) of NO_x,as a proven technology,offers higher NO_x control efficiency than many other NO_x treatment methods.The present work reviews the recent development of SCR reactor technologies.Firstly,catalysts and mechanism of different SCRs were briefly summarized.Different SCR reactors,e.g.structured reactor,fluidized bed reactor and moving bed reactor,were then discussed.As a more advanced technology,multifunctional reactors were also developed for SCR process and could be divided into two categories:decoupled adsorption-reaction process and combined SCR system.The mechanism and properties of these processes were discussed in detail.Some recommendations were given for the future work in SCR reactor design.SCR reactor technology for emerging energy processes was also addressed,such as oxyfuel combustion and biofuel conversion processes,which put forward new requirements for SCR technologies and also open new opportunities for advanced design of SCR reactors. | Xingxing Cheng Xiaotao T.Bi | 2014 | Particuology2014，12，5： | 23 |
| 2 | Polyethylene Oxide-Coated Electrospun Polyimide Fibrous Seperator for High-Performance Lithium-Ion Battery显示文摘A polyethylene oxide(PEO)-coated polyimide(PI) membrane was prepared by electrospinning method followed by a dip-coating and drying process for high-performance lithium-ion batteries(LIB). Semicrystal PEO was covered on the surface of the fibers and partially enmeshed in PI matrix, which formed unique porous structures. The pores with an average size of 4.1 μm and a porosity of 90% served as ion transport channels. Compared with the cell with Celgard 2400 membrane, the half-cell using PEO-coated PI membrane as a separator exhibits excellent electrochemical performance both at room temperature and at low temperature. The electrolyte uptaking rate of PEO-coated PI membrane was 170% and the ionic conductivity was 3.83 × 10^(–3)S cm^(–1). PEO-coated PI membrane possessed 5.3 V electrochemical window.The electrode–electrolyte interfacial resistance was 62.4 Ω. The capacity retention ratios with PEOcoated PI membrane were 86.4% at 5 C and 73.5% at 10 C at 25 ℃ and 75% at 5 C at 0 ℃. Furthermore,the cell using the separator demonstrates excellent capacity retention over cycling. These advanced characteristics would boost the application of the PEO-coated PI membrane for high-power lithium ion battery. | Xingxing Liang Ying Yang Xin Jin Jie Cheng | 2016 | Journal of Materials Science & Technology2016，32，3： | 5 |
| 3 | Glycerol carbonate synthesis from glycerol and dimethyl carbonate using guanidine ionic liquids显示文摘A large number of surplus glycerol from the biodiesel production can be used as renewable feedstock to produce glycerol carbonate. In this paper, a series of guanidine-based ionic liquids were synthesized to catalyze the transesterification of glycerol and dimethyl carbonate. The tunable basicity and the anion–cation cooperative effect were responsible for the obtained results. The [TMG][TFE] showed the best activity turnover frequency(TOF)of 1754.0 h^(-1), glycerol(GL) conversion of 91.8%, glycerol carbonate(GC) selectivity of 95.5%) at 80 °C with 0.1 mol% catalyst for 30 min. The reaction mechanism of the transesterification was also proposed. | Xingxing Wang Peng Zhang Penglei Cui Weiguo Cheng Suojiang Zhang | 2017 | Chinese Journal of Chemical Engineering2017，25，9： | 5 |
| 4 | Adsorption and Regeneration of Volatile Organic Compounds(VOCs)on Coal-Based Activated Carbon by Ferric Nitrate Modification显示文摘In this study,the Heishan coal was used to prepare a series of activated carbon(AC)samples via a vapor deposition method.The effects of the Fe(NO_(3))3/coal weight ratio on the physicochemical properties of the activated carbon were systematically investigated,and the AC samples were analyzed by the N2 adsorption-desorption technique,the scanning electron microscopy,the X-ray diffraction,the Raman spectroscopy,and the Fourier transform infrared spectroscopy.Furthermore,the adsorption properties of ethyl acetate were investigated.The results indicated that as the Fe(NO_(3))3/coal mass ratio increased from 1:8 to 1:2,the specific surface area,the total pore volume and the micropore volume initially increased and then decreased.The specific surface area increased from 560.86 m^(2)/g to 685.90 m^(2)/g,and then decreased to 299.56 m^(2)/g.The total pore volume and micropore volume increased from 0.29 cm^(3)/g and 0.17 cm^(3)/g to 0.30 cm^(3)/g and 0.22 cm^(3)/g,and then decreased to 0.16 cm^(3)/g and 0.10 cm^(3)/g,respectively.The optimized ratio was 1:8.During the activation process,iron ions infiltrated the activated carbon to promote the development of the pore structure,the pore size of which was between 2.5 nm and 3 nm in daimeter.This approach could enhance the capacity for adsorption of ethyl acetate.It is worth noting that the ACs displaying the largest specific surface area and total pore volume(685.90 m^(2)/g and 0.30 cm^(3)/g)were formed under the optimized activation conditions(950℃,20%(volume)of CO_(2),ratio 1:5),and the maximum AC capacity for adsorption of ethyl acetate was 962.62 mg/g.After seven repeated thermal regeneration experiments,the saturated AC adsorption capacity was still above 90%. | Jin Chunjiang Chen Huimin Wang Luyuan Cheng Xingxing Sun Rongfeng | 2021 | China Petroleum Processing & Petrochemical Technology2021，23，3： | 4 |
| 5 | Identification of stably expressed QTL for resistance to black shank disease in tobacco(Nicotiana tabacum L.) line Beinhart 1000-1显示文摘Cigar line Beinhart 1000-1 has effective durable resistance to black shank(BS) and is considered one of the most resistant sources in tobacco(Nicotiana tabacum L.). To investigate the inheritance and identification of stable quantitative trait loci(QTL) for BS response, F2,BC1 F2 individuals and BC1 F2:3 lines were produced from a cross between Beinhart 1000-1 and Xiaohuangjin 1025. Two major quantitative trait loci(M-QTL) named qBS7 and qBS17 were repeatedly detected under different conditions. QTL qBS7 was mapped to the region between PT30174 and PT60621 and explained 17.40%–25.60% of the phenotypic variance under different conditions. The other QTL qBS17 in interval PT61564–PT61538 of linkage group 17 was detected in a BC1 F2 population in the field and in BC1 F2:3 in both the field and at the seedling stage, explaining 6.90% to 11.60% of the phenotypic variance. The results improve our understanding of the inheritance of resistance to BS and provide information that can be used in marker-assisted breeding. | Yusheng Zhang Xuan Guo Xingxing Yan Min Ren Caihong Jiang Yazeng Cheng Liuying Wen Dan Liu Yu Zhang Mingming Sun Quanfu Feng Aiguo Yang Lirui Cheng | 2018 | The Crop Journal2018，6，3： | 4 |
| 6 | Genetic diversity assessment of a set of introduced mung bean accessions(Vigna radiata L.)显示文摘Genetic resources from other countries or regions play an important role in broadening the genetic background of local breeding varieties. Here we describe observations on the adaptability of mung bean germplasm obtained from the United States Department of Agriculture and their genetic diversity assessment using SSR markers. Several accessions were shown to be mixtures,based on their phenotypes for some characters. Most accessions were able to complete their lifecycles when grown in Beijing, China, making them ideal for crossbreeding without day length control. High diversity was revealed by the SSR markers, with an average of 4.2 alleles per locus and a PIC value of 0.650 per locus. STRUCTURE analysis divided the accessions into six groups.There was no obvious trend of accessions forming groups according to their geographical origin,owing mainly to germplasm exchange and an uneven distribution of accessions. The present results indicate that this germplasm would enrich the local gene pool, and provide information for the further use of germplasm in breeding programs. | Lixia Wang Peng Bai Xingxing Yuan Honglin Chen Suhua Wang Xin Chen Xuzhen Cheng | 2018 | The Crop Journal2018，6，2： | 3 |
| 7 | A lake ice phenology dataset for the Northern Hemisphere based on passive microwave remote sensing显示文摘Lake ice phenology(LIP)is an essential indicator of climate change and helps with understanding of the regional characteristics of climate change impacts.Ground observation records and remote sensing retrieval products of lake ice phenology are abundant for Europe,North America,and the Tibetan Plateau,but there is a lack of data for inner Eurasia.In this work,enhanced-resolution passive microwave satellite data(PMW)were used to investigate the Northern Hemisphere Lake Ice Phenology(PMW LIP).The Freeze Onset(FO),Complete Ice Cover(CIC),Melt Onset(MO),and Complete Ice Free(CIF)dates were derived for 753 lakes,including 409 lakes for which ice phenology retrievals were available for the period 1978 to 2020 and 344 lakes for which these were available for 2002 to 2020.Verification of the PMW LIP using ground records gave correlation coefficients of 0.93 and 0.84 for CIC and CIF,respectively,and the corresponding values of the RMSE were 11.84 and 10.07 days.The lake ice phenology in this dataset was significantly correlated(P<0.001)with that obtained from Moderate Resolution Imaging Spectroradiometer(MODIS)data-the average correlation coefficient was 0.90 and the average RMSE was 7.87 days.The minimum RMSE was 4.39 days for CIF.The PMW is not affected by the weather or the amount of sunlight and thus provides more reliable data about the freezing and thawing process information than MODIS observations.The PMW LIP dataset pro-vides the basic freeze-thaw data that is required for research into lake ice and the impact of climate change in the cold regions of the Northern Hemisphere.The dataset is available at http://gffzza4c772bdab62464fh9uook9kquw0566qw.ffgz.tsg.suse.edu.cn/10.11922/sciencedb.j00076.00081. | Xingxing Wang Yubao Qiu Yixiao Zhang Juha Lemmetyinen Bin Cheng Wenshan Liang Matti Leppäranta | 2022 | Big Earth Data2022，6，4： | 2 |
| 8 | Research on prediction model of formation temperature of ammonium bisulfate in air preheater of coal-fired power plant显示文摘Ammonium bisulfate(ABS)is a viscous compound produced by the escape NH_(3) in the NO reduction process and SO_(3) in the flue gas at a certain temperature,which can cause the ash corrosion of the air preheater in coal-fired power plants.Therefore,it is essential to study the formation temperature of ABS to prevent the deposition of ABS in air preheaters.In this paper,the SO_(3) reaction kinetic model is used to analyze the SO_(3) generation process from coal combustion to the selective catalytic reduction(SCR)exit stage,and the kinetic model of NO reduction is used to analyze the NH_(3) escape process.A prediction model for calculating the ABS formation temperature based on the S content in coal and NO reduction parameters of the SCR is proposed,solving the difficulty of measuring SO_(3) concentration and NH_(3) concentration in the previous calculation equation of ABS formation temperature.And the reliability of the model is verified by the actual data of the power plant.Then the influence of S content in coal,NH_(3)/NO_(x) molar ratio,different NO_(x) concentrations at SCR inlet,and NO removal efficiency on the formation temperature of ABS are analyzed. | Kai Zhang Fangming Xue Zhiqiang Wang Xingxing Cheng | 2022 | Chinese Journal of Chemical Engineering2022，35，8： | 2 |
| 9 | A potent PGK1 antagonist reveals PGK1 regulates the production of IL-1βand IL-6显示文摘Glycolytic metabolism enzymes have been implicated in the immunometabolism field through changes in metabolic status. PGK1 is a catalytic enzyme in the glycolytic pathway. Here, we set up a high-throughput screen platform to identify PGK1 inhibitors. DC-PGKI is an ATPcompetitive inhibitor of PGK1 with an affinity of Kd= 99.08 nmol/L. DC-PGKI stabilizes PGK1in vitro and in vivo, and suppresses both glycolytic activity and the kinase function of PGK1. In addition,DC-PGKI unveils that PGK1 regulates production of IL-1β and IL-6 in LPS-stimulated macrophages.Mechanistically, inhibition of PGK1 with DC-PGKI results in NRF2(nuclear factor-erythroid factor 2-related factor 2, NFE2L2) accumulation, then NRF2 translocates to the nucleus and binds to the proximity region of Il-1β and Il-6 genes, and inhibits LPS-induced expression of these genes. DC-PGKI ameliorates colitis in the dextran sulfate sodium(DSS)-induced colitis mouse model. These data support PGK1 as a regulator of macrophages and suggest potential utility of PGK1 inhibitors in the treatment of inflammatory bowel disease. | Liping Liao Wenzhen Dang Tingting Lin Jinghua Yu Tonghai Liu Wen Li Senhao Xiao Lei Feng Jing Huang Rong Fu Jiacheng Li Liping Liu Mingchen Wang Hongru Tao Hualiang Jiang Kaixian Chen Xingxing Diao Bing Zhou Xiaoyan Shen Cheng Luo | 2022 | Acta Pharmaceutica Sinica B2022，12，11： | 2 |
| 10 | Bioactive skin-mimicking hydrogel band-aids for diabetic wound healing and infectious skin incision treatment显示文摘The treatment of diabetic chronic wounds remains a global challenge due to the up-regulated inflammation response,oxidant stress,and persistent infection during healing process.Developing wound dressing materials with ideal biocompatibility,adequate mechanical strength,considerable under-water adhesion,sufficient anti-inflammation,antioxidant,and antibacterial properties is on-demand for clinical applications.In this study,we developed a bioactive skin-mimicking hydrogel band-aid through the combination of tannic acid(TA)and imidazolidinyl urea reinforced polyurethane(PMI)(TAP hydrogel)and explored its potentials in various medical applications,including hemostasis,normal skin incision,full-thickness skin wounds,and bacterial-infection skin incision on diabetic mice.TA was loaded into PMI hydrogel network to enhance the mechanical properties of TAP hydrogels through multiple non-covalent interactions(break strength:0.28-0.64 MPa;elongation at break:650-930%),which could resist the local stress and maintain the structural integrity of wound dressings during applications.Moreover,owing to the promising moisture-resistant adhesiveness and organ hemostasis,outstanding anti-inflammation,antibacterial,and antioxidant properties,TAP hydrogels could efficiently promote the recovery of skin incision and defects on diabetic mice.To further simulate the practical situation and explore the potential in clinical application,we also verified the treatment efficiency of TAP hydrogel in S.aureus-infected skin incision model on diabetic mice. | Yuxuan Yang Xiaodan Zhao Jing Yu Xingxing Chen Ruyue Wang Mengyuan Zhang Qiang Zhang Yanfeng Zhang Shuang Wang Yilong Cheng | 2021 | Bioactive Materials2021，6，11： | 2 |
| 11 | High-speed optical secure communication with an external noise source and an internal time-delayed feedback loop显示文摘We propose and experimentally demonstrate a novel physical layer encryption scheme for high-speed optical communication. A 10 Gb/s on-off keying signal is secretly transmitted over 100 km standard single-mode fiber.The intensity-modulated message is secured by the encryption mechanism, which is composed of an external noise source and an internal time-delayed feedback loop. The external noise serves as an entropy source with sufficient randomness. The feedback loop structure in the transmitter introduces a time-domain encryption key space, and a corresponding open-loop configuration at the receiver side is used for synchronization and decryption.Experiment results show the effectiveness of the proposed scheme. For a legitimate terminal, bit error rate below10-8 can be obtained. Decryption degradations with the mismatch of different hardware parameters are researched. The time delay in the feedback loop provides a sensitive encryption key. For other hardware parameters,the system is robust enough for synchronization. Meanwhile, the time-delay signature of the loop is able to be well concealed by the external noise. Moreover, the proposed scheme can support density wavelength division multiplexing transmission with a relatively simple structure. This work also provides a new concept to establish optical secure communication by combining a time-delayed feedback chaotic system and random noise. | YUDI FU MENGFAN CHENG XINGXING JIANG QUAN YU LINBOJIE HUANG LEI DENG DEMING LIU | 2019 | Photonics Research2019，7，11： | 2 |

| 16 | Distinct expression profiles and overlapping functions of IL-4/13A and IL-4/ 13B in grass carp (Ctenopharyngodon idella)显示文摘In mammals,interleukin(IL)-4 and IL-13 are important cytokines involved in the immune response of the host defence against pathogens and play critical roles in the polarization of monocytes/macrophages(MO/Mϕs).However,in teleost fish,the role of IL-4/13 homologues in the polarization of MO/Mϕremains unknown.In this paper,we identified a second isoform of IL-4/13(CiIL-4/13A)from grass carp(Ctenopharyngodon idella)in addition to the IL-4/13 homologue previously reported and comparatively studied their expression profiles and functions.The two CiIL-4/13 transcripts were constitutively expressed in tissues but displayed distinct expression patterns.Infection with Flavobacterium columnare or grass carp reovirus II(GCRV-Ⅱ)resulted in the alteration of expression levels of both IL-4/13 isoforms.Furthermore,in the primary head kidney cells,the recombinant CiIL-4/13A and B could up-regulate the expression of IL-10,inducible nitric oxide synthase(iNOS)and M2 macrophage marker gene(KLF4,kruppel like factor 4),whilst down-regulate the expression of IL-1βand M1 macrophage marker gene(MARCO,macrophage receptor with collagenous structure).The results suggest that the CiIL-4/13A and B play similar roles in regulating inflammation and differentiation of MO/Mϕs in grass carp. | Xinyu Jiang Junya Wang Shuai Wan Yujie Xue Zhaosheng Sun Xingxing Cheng Qian Gao Jun Zou | 2020 | Aquaculture and Fisheries2020，5，2： | 1 |

| 18 | Fewer is more:efficient object detection in large aerial images显示文摘Current mainstream object detection methods for large aerial images usually divide large images into patches and then exhaustively detect the objects of interest on all patches,no matter whether there exist objects or not.This paradigm,although effective,is inefficient because the detectors have to go through all patches,severely hindering the inference speed.This paper presents an objectness activation network(OAN) to help detectors focus on fewer patches but achieve more efficient inference and more accurate results,enabling a simple and effective solution to object detection in large images.In brief,OAN is a light fully-convolutional network for judging whether each patch contains objects or not,which can be easily integrated into many object detectors and jointly trained with them end-to-end.We extensively evaluate our OAN with five advanced detectors.Using OAN,all five detectors acquire more than 30.0% speed-up on three large-scale aerial image datasets,meanwhile with consistent accuracy improvements.On extremely large Gaofen-2 images(29200 × 27620 pixels),our OAN improves the detection speed by 70.5%.Moreover,we extend our OAN to driving-scene object detection and 4K video object detection,boosting the detection speed by 112.1% and 75.0%,respectively,without sacrificing the accuracy. | Xingxing XIE Gong CHENG Qingyang LI Shicheng MIAO Ke LI Junwei HAN | 2024 | Science China(Information Sciences)2024，67，1： | 1 |
| 19 | Proximity-enabled covalent binding of IL-2 to IL-2Rα selectively activates regulatory T cells and suppresses autoimmunity显示文摘Interleukin-2(IL-2)is a pleiotropic cytokine that orchestrates bidirectional immune responses via regulatory T cells(Tregs)and effector cells,leading to paradoxical consequences.Here,we report a strategy that exploited genetic code expansion-guided incorporation of the latent bioreactive artificial amino acid fluorosulfate-L-tyrosine(FSY)into IL-2 for proximity-enabled covalent binding to IL-2Rαto selectively promote Treg activation.We found that FSY-bearing IL-2 variants,such as L72-FSY,covalently bound to IL-2Rαvia sulfur-fluoride exchange when in proximity,resulting in persistent recycling of IL-2 and selectively promoting the expansion of Tregs but not effector cells.Further assessment of L72-FSY-expanded Tregs demonstrated that L72-FSY maintained Tregs in a central memory phenotype without driving terminal differentiation,as demonstrated by simultaneously attenuated expression of lymphocyte activation gene-3(LAG-3)and enhanced expression of programmed cell death protein-1(PD-1).Subcutaneous administration of L72-FSY in murine models of pristane-induced lupus and graft-versus-host disease(GvHD)resulted in enhanced and sustained therapeutic efficacy compared with wild-type IL-2 treatment.The efficacy of L72-FSY was further improved by N-terminal PEGylation,which increased its circulatory retention for preferential and sustained effects.This proximity-enabled covalent binding strategy may accelerate the development of pleiotropic cytokines as a new class of immunomodulatory therapies. | Bo Zhang Jiaqi Sun Yeshuang Yuan Dezhong Ji Yeting Sun Yudong Liu Shengjie Li Xingxing Zhu Xunyao Wu Jin Hu Qiu Xie Ling Wu Lulu Liu Boyang Cheng Yuanjie Zhang Lingjuan Jiang Lidan Zhao Fei Yu Wei Song Min Wang Yue Xu Shiliang Ma Yunyun Fei Lihe Zhang Demin Zhou Xuan Zhang | 2023 | Signal Transduction and Targeted Therapy2023，8，2： | 0 |
| 20 | Nickel phosphide for MRI-guided synergistic photo-immunotherapy显示文摘Developing a phototherapy modality to ablate tumor and then trigger immunogenic cell death(ICD)for simultaneously eliminating distal and metastatic tumors holds great promise in clinical applications.Herein,the polyethylene glycol functionalized Ni_(2)P(Ni_(2)P@PEG NPs)is developed with enhanced biocompatibility,high photoabsorption and photothermal efficiency,as well as reactive oxygen species generation ability.Of particular note,Ni_(2)P@PEG NPs mediated phototherapy could not only realize efficient ablation of primary tumors,but also inhibit distal tumors and metastatic tumors by triggering an antitumor immune response.The above conclusions were verified by B mode ultrasound,western blot assay,and immunohistochemistry analysis.Meanwhile,Ni_(2)P@PEG NPs showed excellent magnetic resonance imaging(MRI)properties.In summary,the MRI-guided multimodal cancer therapies of Ni_(2)P@PEG NPs represent significant potential for clinical applications. | Na An Yan Gao Ying Shi Xingxing Du Jianing Cheng Shuanglong Tang Pengfei Liu Huike Yang Chongshen Guo | 2023 | Journal of Materials Science & Technology2023，，20： | 0 |
