| 1 | Study on the recovery of hydrogen from refinery (hydrogen+methane) gas mixtures using hydrate technology显示文摘A novel technique for separating hydrogen from (H2 + CH4) gas mixtures through hydrate formation/dissociation was proposed. In this work, a systematic experimental study was performed on the separation of hydrogen from (H2 + CH4) feed mixtures with various hydrogen contents (mole fraction x = 40%-90%). The experimental results showed that the hydrogen content could be enriched to as high as ~94% for various feed mixtures using the proposed hydrate technology under a temperature slightly above 0℃ and a pressure below 5.0 MPa. With the addition of a small amount of suitable additives, the rate of hydrate formation could be increased significantly. Anti-agglomeration was used to disperse hydrate particles into the condensate phase. Instead of preventing hydrate growth (as in the kinetic inhibitor tests), hydrates were allowed to form, but only as small dispersed particles. Anti-agglomeration could keep hydrate particles suspended in a range of condensate types at 1℃ and 5 MPa in the water-in-oil emulsion. | WANG XiuLin CHEN GuangJin YANG LanYing ZHANG LinWei | 2008 | Science China Chemistry2008，51，2： | 17 |
| 2 | Segmentation of Hematoxylin-Eosin stained breast cancer histopathological images based on pixel-wise SVM classifier显示文摘Hematoxylin-Eosin(HE) staining is the routine diagnostic method for breast cancer(BC), and large amounts of HE stained histopathological images are available for analysis. It is emergent to develop computational methods to efficiently and objectively analyze these images, with the aim of providing potentially better diagnostic and prognostic information for BC. This work focuses on analyzing our in-house HE stained histopathological images of breast cancer tissues. Since tumor nests(TNs) and stroma morphological characteristics can reflect the biological behaviors of breast invasive ductal carcinoma(IDC), accurate segmentation of TNs and the stroma is the first step towards the subsequent quantitative analysis. We first propose a method based on the pixel-wise support vector machine(SVM) classifier for segmenting TNs and the stroma, then extract four morphological characters related to the TNs from the images and investigate their relationships with the patients' 8-year disease free survival(8-DFS). The evaluation result shows that the classification based segmentation method is able to distinguish between TNs and stroma with 87.1% accuracy and 80.2% precision,suggesting that the proposed method is promising in segmenting HE stained IDC histopathological images. The Kaplan-Meier survival curves show that three morphological characters(number of TNs, total perimeter, and average area of TNs) in the images have statistical correlations with 8-DFS of the patients, illustrating that the segmented images can help to identify new morphological factors in IDC TNs for the prediction of BC prognosis. | QU AiPing CHEN JiaMei WANG LinWei YUAN JingPing YANG Fang XIANG QingMing MASKEY Ninu YANG GuiFang LIU Juan LI Yan | 2015 | Science China(Information Sciences)2015，58，9： | 12 |
| 3 | Near-perfect fidelity polarization-encoded multilayer optical data storage based on aligned gold nanorods显示文摘Encoding information in light polarization is of great importance in facilitating optical data storage(ODS)for information security and data storage capacity escalation.However,despite recent advances in nanophotonic techniques vastly en-hancing the feasibility of applying polarization channels,the data fidelity in reconstructed bits has been constrained by severe crosstalks occurring between varied polarization angles during data recording and reading process,which gravely hindered the utilization of this technique in practice.In this paper,we demonstrate an ultra-low crosstalk polarization-en-coding multilayer ODS technique for high-fidelity data recording and retrieving by utilizing a nanofibre-based nanocom-posite film involving highly aligned gold nanorods(GNRs).With parallelizing the gold nanorods in the recording medium,the information carrier configuration minimizes miswriting and misreading possibilities for information input and output,respectively,compared with its randomly self-assembled counterparts.The enhanced data accuracy has significantly im-proved the bit recall fidelity that is quantified by a correlation coefficient higher than 0.99.It is anticipated that the demon-strated technique can facilitate the development of multiplexing ODS for a greener future. | Linwei Zhu Yaoyu Cao Qiuqun Chen Xu Ouyang Yi Xu Zhongliang Hu Jianrong Qiu Xiangping Li | 2021 | Opto-Electronic Advances2021，4，11： | 9 |
| 4 | Strategies of Removing Residual Lithium Compounds on the Surface of Ni-Rich Cathode Materials显示文摘Ni-rich cathode materials have become one of the most promising cathode materials for advanced high-energy Li-ion batteries(LIBs)owing to their high specific capacity.However,Ni-rich cathode materials are sensitive to the trace H2O and CO2 in the air,and tend to react with them to generate LiOH and Li2COg at the particle surface region(named residual lithium compounds,labeled as RLCs).The RLCs will deteriorate the comprehensive performances of Ni-rich cathode materials and make trouble in the subsequent manufacturing process of electrode,including causing low initial coulombic efficiency and poor storage property,bringing about potential safety hazards,and gelatinizing the electrode slurry.Therefore,it is of considerable significance to remove the RLCs.Researchers have done a lot of work on the corresponding field,such as exploring the formation mechanism and elimination methods.This paper investigates the origin of the surface residual lithium compounds on Ni-rich cathode materials,analyzes their adverse effects on the per-formance and the subsequent electrode production process,and summarizes various kinds of feasible methods for removing the RLCS.Finally,we propose a new research direction of eliminating the lithium residuals after comparing and summing up the above.We hope this work can provide a reference for alleviating the adverse effects of residual lithium compounds for Ni-rich cathode materials'industrial production. | Yuefeng Su Linwei Li Gang Chen Lai Chen Ning Li Yun Lu Liying Bao Shi Chen Feng Wu | 2021 | Chinese Journal of Chemistry2021，39，1： | 4 |
| 5 | Efficient separation between trivalent americium and lanthanides enabled by a phenanthroline-based polymeric organic framework显示文摘Separation of the minor actinides(Am and Cm)from lanthanides in high-level liquid wastes(HLLW)is one of the most challenging chemical separation tasks known owing to their chemical similarities and is highly significant in nuclear fuel reprocessing plants because it could practically lead to sustainable nuclear energy by closing the nuclear fuel cycle.The solid phase extraction is proposed to be a possible strategy but all reported sorbent materials severely suffer from limited stability and/or efficiency caused by the harsh conditions of high acidity coupled with intense irradiation.Herein,a phenanthroline-based polymeric organic framework(PhenTAPB-POF)was designed and tested for the separation of trivalent americium from lanthanides for the first time.Due to its fully conjugated structure,PhenTAPB-POF exhibits previously unachieved stability under the combined extreme conditions of strong acids and high irradiation field.The americium partitioning experiment indicates that PhenTAPB-POF possesses an ultrahigh adsorption selectivity towards Am(Ⅲ)over lanthanides(e.g.,SFAm(Ⅲ)/Eu(Ⅲ)=3326)in highly acidic simulated HLLW and relatively fast adsorption kinetics in both static and dynamic experiments.Am(Ⅲ)can be almost quantitatively eluted from the PhenTAPB-POF packed-column using a concentrated nitric acid elution.The high stability and superior separation performance endow PhenTAPB-POF with the promising alternative for separating minor actinides over lanthanides from highly acidic HLLW streams. | Afshin Khayambashi Long Chen Xue Dong Kai Li Zhipeng Wang Linwei He Suresh Annam Lixi Chen Yaxing Wang Matthew V.Sheridan Chao Xu Shuao Wang | 2022 | Chinese Chemical Letters2022，33，7： | 1 |

| 13 | Reverse-Time Migration of Converted S-Waves of Varying Densities显示文摘Ocean-Bottom Node(OBN)acquisitions provide both non-converted and converted reflection energy.There is a clear advantage to independently imaging both P-and S-waves,as they provide more information collectively than either does alone.In many conventional converted-wave pre-stack migration algorithms,density is treated as a constant,which is not the real-life case on earth.S-wave velocity and density information is crucial for hydrocarbon detection because it helps in the identification of porefilling fluids.In this paper,we focused on the effect of density on imaging,and developed a method of reverse-time migration(RTM)on converted s-waves of varying densities(VD-RTMCS).Phase correction was required prior to pre-stack migration to avoid constructive interference between data from adjacent sources.Synthetic data examples showed that when density variations were included,image profiles showed advantages in signal-to-noise ratio,vertical resolution and imaging of complex structures. | TONG Siyou CHEN Ming ZHOU Huawei LI Linwei XU Xiugang WU Zhiqiang | 2019 | Journal of Ocean University of China2019，18，5： | 1 |

| 15 | Radiation-induced one-pot synthesis of grafted covalent organic frameworks显示文摘Post-synthetic functionalization of covalent organic frameworks(COFs)is an alternative way to enhance and broaden their properties and potential applications.However,the chemical functionalization of COFs is a great challenge because traditional procedures are often time-and energy-consuming,while the crystallinity of COFs can be damaged under harsh conditions.Here we report the in-situ introduction of functional graft chains onto the skeleton of COFs during the synthesis process through the combination of radiation-induced synthesis and graft polymerization techniques under ^(60)Co gamma-ray radiation.The synthesis and functionalization of COFs are simultaneously accomplished in a chemical system under ambient conditions yielding a large number of different functionalized COFs.The obtained carboxyl-functionalized COFs exhibit excellent radioactive uranium removal capabilities from aqueous solution with fast uptake dynamics,high adsorption capacity,and excellent selectivity over other competing metal ions. | Mingxing Zhang Mengjia Yuan Xiaofang Zhao Junchang Chen Linwei He Qianhong Gao Jiangtao Hu Guozhong Wu Zhifang Chai Shuao Wang | 2023 | Science China Chemistry2023，66，6： | 0 |
| 16 | Assessing mechanisms for microbial taxa and community dynamics using process models显示文摘Disentangling the assembly mechanisms controlling community composition,structure,distribution,functions,and dynamics is a central issue in ecology.Although various approaches have been proposed to examine community assembly mechanisms,quanti-tative characterization is challenging,particularly in microbial ecology.Here,we present a novel approach for quantitatively delineating community assembly mechanisms by combining the consumer–resource model with a neutral model in stochastic differential equations.Using time-series data from anaerobic bioreactors that target microbial 16S rRNA genes,we tested the applicability of three ecological models:the consumer–resource model,the neutral model,and the combined model.Our results revealed that model performances varied substantially as a function of population abundance and/or process conditions.The combined model performed best for abundant taxa in the treatment bioreactors where process conditions were manipulated.In contrast,the neutral model showed the best performance for rare taxa.Our analysis further indicated that immigration rates decreased with taxa abundance and com-petitions between taxa were strongly correlated with phylogeny,but within a certain phylogenetic distance only.The determinism underlying taxa and community dynamics were quantitatively assessed,showing greater determinism in the treatment bioreactors that aligned with the subsequent abnormal system functioning.Given its mechanistic basis,the framework developed here is expected to be potentially applicable beyond microbial ecology. | Linwei Wu Yunfeng Yang Daliang Ning Qun Gao Huaqun Yin Naija Xiao Benjamin YZhou Si Chen Qiang He Jizhong Zhou | 2023 | mLife2023，2，3： | 0 |
| 17 | Chromate separation by selective crystallization显示文摘A new paradigm to remove toxic chromate anions from aqueous solution by crystallization of chromatewater clusters with imine-linked guanidinium cationic ligands is introduced.The guanidium-based cationic ligand was easily prepared through the imine condensation of an alde hyde and aminoguanidine hydrochloride.The cationic imine-linked guanidinium liga nd(BBIG-CI)showed a high re moval capacity(292.5 mg/g)in the solutions.Rapid decontamination of chromate anions from the wastewater by this cationic ligand was resulted from an instantaneous crystallization.The produced guanidium chromate salts have an extremely low solubility(Ksp,BBIG=8.19×10^9).Such superior removal performance of these mate rials was attributed to the cha rge-assisted hydrogen bonding between the cationic ligand and chromate-water hydrate anions,which was revealed by the single-crystal X-ray diffraction analysis and density functional theory(DFT)calculations.In addition,the succes s ful recove ry of the guanidium-based ligand makes it more attractive for real-world applications. | Xijian Chen Xing Dai Rongzhen Xie Jie Li Afshin Khayambashi Lei Xu Chuang Yang Nannan Shen Yaxing Wang Linwei He Yugang Zhang Chengliang Xiao Zhifang Chai Shuao Wanga | 2020 | Chinese Chemical Letters2020，31，7： | 0 |
| 18 | Synergy of first-and second-sphere interactions in a covalent organic framework boosts highly selective platinum uptake显示文摘Platinum recovery from waste electrical and electronic equipment(WEEE) in highly acidic solutions is significant to the electronics industry and environmental remediation. However, the lack of ingenious design and synergetic coordination gives rise to unsatisfied PtCl_(4)^(2-)extraction capacities and selectivities in most previously reported adsorbents(e.g., polymeric and inorganic materials). Herein, we proposed a synergistic strategy that realizes highly selective PtCl_(4)^(2-)uptake through first-and second-sphere coordinations. The proof-of-concept imine-linked covalent organic framework(SCU-COF-3) was found to chelate Pt Cl42-via the direct N…Pt coordination and the synergistically interlaminar N–H…Cl hydrogen bonds, which was disclosed by the comprehensive analysis of extended X-ray adsorption fine structure(EXAFS) characterizations and density functional theory(DFT) calculations. The unique adsorption mechanism imparts a superior adsorption capacity(168.4 mg g-1)and extraordinary Pt(II) selectivity to SCU-COF-3 under static conditions. In addition, SCU-COF-3 exhibits an upgraded distribution coefficient of 1.62 × 10^(5)mL· g^(-1), one order of magnitude higher than those of reported natural adsorbents. Specifically, SCU-COF-3 can extract PtCl_(4)^(2- )quantitatively from a simulated acidic waste solution coexisting with other 12 competitive ions, suggesting its promising application in practical scenarios. | Linwei He Baoyu Li Zhonglin Ma Lixi Chen Shicheng Gong Mingxing Zhang Yaoyao Bai Qi Guo Fuqi Wu Fuqiang Zhao Jie Li Duo Zhang Daopeng Sheng Xing Dai Long Chen Jie Shu Zhifang Chai Shuao Wang | 2023 | Science China Chemistry2023，66，3： | 0 |
| 19 | Superior Iodine Uptake Capacity Enabled by an Open Metal-Sulfide Framework Composed of Three Types of Active Sites显示文摘Efficient adsorption of gaseous radioiodine is pivotal for the sustainable development of nuclear energy and the long-termradiation safety of the ecological system.However,state-of-the-art adsorbents(e.g.metal-organic frameworks and covalent-organic frameworks)currently under exploration suffer severely from limited adsorption capacity,especially under a real-world scenariowith extremely lowradioiodine concentration and elevated temperature.This mostly originates from the relatively weak sorption driving forces mainly determinedby the iodine-adsorbent interaction consistingof noncovalent interactionswith a small fraction of strong chemical bonding.Here,we document the discovery of an open metal-sulfide framework((NH_(4))_(2)(Sn_(3)S_(7)),donated as SCU-SnS)constructed by three different types of active sites as a superior iodine adsorbent.Benefiting from the ability of iodine for pre-enrichment into the framework by charge-balancing NH_(4)^(+)through N-H···I interaction,the efficient reduction of I^(2)affording I^(-)by S^(2-),and extremely high binding affinity between Sn_(4)^(+)and I^(-),SCU-SnS exhibit a record-breaking iodine adsorption capacity(2.12 g/g)under dynamic breakthrough conditions and the highest static capacity(6.12 g/g)among all reported inorganic adsorbents,both at 348 K.Its facile synthesis and low cost endow SCU-SnS with powerful application potential for the nuclear industry. | Yugang Zhang Linwei He Tingting Pan Jian Xie Fuqi Wu Xinglong Dong Xia Wang Lixi Chen Shicheng Gong Wei Liu Litao Kang Junchang Chen Lanhua Chen Long Chen Yu Han Shuao Wang | 2023 | CCS Chemistry2023，5，7： | 0 |
| 20 | Structural effects of sulfonamides on the proliferation dynamics of sulfonamide resistance genes in the sequencing batch reactors and the mechanism显示文摘Antibiotic resistance genes(ARGs)can be easily promoted by antibiotics,however,the structural effects of antibiotics on the proliferation of ARGs dynamic and the associated mechanisms remain obscure in,especially,activated sludge sequencing batch reactors.In the present study,the effects of 9 sulfonamides(SAs)with different structures on the proliferation dynamic of sulfonamide resistance genes(Suls)in the activated sludge sequencing batch reactors and the corresponding mechanisms were determined(30 days),and the results showed that the largest proliferation value(ΔA^(R))of Suls dynamic for SAs(sulfachloropyridazine)was approximately 2.9 times than that of the smallest one(sulfadiazine).The proliferation of Suls was significantly related to the structural features(minHBint6,SssNH,SHBd and SpMax2_Bhm)that represent the biological activity of SAs.To interpret the phenomenon,a mechanistic model was developed and the results indicated that the biodegradation of SAs(T_(1/2))rather than conjugative transfer frequency or mutation frequency tends to be the key process for affecting Suls proliferation.T_(1/2)was proved to be dependent on the interactions between SAs and receptors(E_(binding)),the cleavage mode(bond dissociation energy),and the site of nucleophilic assault.Besides,the metagenomic analysis showed that SAs posed significant effect on antibiotic resistome and Tnp31 played a vital role in the proliferation of Suls.Overall,our findings provide important insight into a theoretical basis for understanding the structural effects of SAs on the proliferation of ARGs in SBR systems. | Ligui Wu Mingyu Wang Lingling Rong Wenbiao Wang Linwei Chen Qiaofeng Wu Haoyu Sun Xiangfeng Huang Xiaoming Zou | 2024 | Journal of Environmental Sciences2024，，1： | 0 |
