| 1 | Synthesis of novel nanomaterials and their application in efficient removal of radionuclides显示文摘With the development of nuclear energy, large amounts of radionuclides are inevitably released into the natural environment. It is necessary to eliminate radionuclides from wastewater for the protection of environment. Nanomaterials have been considered as the potential candidates for the effective and selective removal of radionuclides from aqueous solutions under complicated conditions because of their high specific surface area, large amounts of binding sites, abundant functional groups, pore-size controllable and easily surface modification. This review mainly summarized the recent studies for the synthesis, fabrication and surface modification of novel nanomaterials and their applications in the efficient elimination and solidification of radionuclides,and discussed the interaction mechanisms from batch experiments, spectroscopy analysis and theoretical calculations. The sorption capacities with other materials, advantages and disadvantages of different nanomaterials are compared, and at last the perspective of the novel nanomaterials is summarized. | Xiangxue Wang Long Chen Lin Wang Qiaohui Fan Duoqiang Pan Jiaxing Li Fangting Chi Yi Xie Shujun Yu Chengliang Xiao Feng Luo Jun Wang Xiaolin Wang Changlun Chen Wangsuo Wu Weiqun Shi Shuao Wang Xiangke Wang | 2019 | Science China Chemistry2019，62，8： | 20 |
| 2 | Numerical simulation of underwater explosion bubble with a refined interface treatment显示文摘With the intermediate flow states predicted by local two phase Riemann problem,the modified ghost fluid method(MGFM)and its variant(r GFM)have been widely employed to resolve the interface condition in the simulation of compressible multi-medium flows.In this work,the drawback of the construction procedure of local two phase Riemann problem in r GFM was investigated in detail,and a refined version of the construction procedure was specially developed to make the simulation of underwater explosion bubbles more accurate and robust.Beside the refined r GFM,the fast and accurate particle level set method was also adopted to achieve a more effective and computationally efficient capture of the evolving multi-medium interfaces during the simulation.To demonstrate the improvement brought by current refinement,several typical numerical examples of underwater explosion bubbles were performed with original r GFM and refined r GFM,respectively.The results indicate that,when compared with original r GFM,numerical oscillations were effectively removed with the proposed refinement.Accordingly,with present refined treatment of interface condition,a more accurate and robust simulation of underwater explosion bubbles was accomplished in this work. | JIANG Liang GE Han FENG ChengLiang CHEN DaRong | 2015 | Science China(Physics,Mechanics & Astronomy)2015，58，4： | 3 |

| 5 | MODELING AND IMPLEMENTATION OF SPEED GOVERNOR FOR THE HYBRID ELECTRIC VEHICLE ENGINE显示文摘A speed control analysis for an in-line gasoline fueled internal combustion (IC) engine is presented for the purpose of alleviation of high frequency oscillations in engine revolutions. A dynamic cylinder-by-cylinder model is proposed, base on slider-crank mechanism, which is extended to develop a digital governor providing a high fidelity estimation of rotary speed oscillation for hybrid vehicle engines. A modified PID controller that P and I gain is placed in feedback path is also described for hybrid electric vehicle (HEV) engine speed regulation. By comparison between measured and estimated signals, it is demonstrated that a good agreement has been achieved and the governor behaves an excellent damping speed ripple. | Feng Qishan Zhang Jianwu Yin Chengliang | 2005 | Chinese Journal of Mechanical Engineering2005，18，4： | 1 |
| 6 | Facile fabrication of ultrathin freestanding nanoporous Cu and Cu-Ag films with high SERS sensitivity by dealloying Mg-Cu(Ag)-Gd metallic glasses显示文摘Nanoporous metals prepared by dealloying have attracted increasing attention due to their interesting size-dependent physical,chemical,and biological properties.However,facile fabrication of metallic ultrathin freestanding nanoporous films(UF-NPFs)by dealloying is still challenging.Herein,we report a novel strategy of facile preparation of flexible Cu,Cu_(3)Ag,and CuAg UF-NPFs by dealloying thick Mg-Cu(Ag)-Gd metallic glass ribbons.During dealloying,the local reaction latent heat-induced glass transition of the precursor ribbons leads to the formation of a solid/liquid interface between the initially dealloyed nanoporous layer and the underlying supercooled liquid layer.Due to the bulging effect of in situ generated H2 on the solid/liquid interface,Cu,Cu_(3)Ag,and CuAg UF-NPFs with thicknesses of~200 nm can self-peel off from the outer surface of the dealloying ribbons.Moreover,it was found that the surfaceenhanced Raman scattering(SERS)detection limit of Rhodamine 6G(R6G)on the Cu and CuAg UF-NPF substrates are 10^(-6)M and 10^(-11)M,respectively,which are lower than most of the Cu and Cu-Ag substrates prepared by other methods.This work presents a reliable simple strategy to synthesize a variety of cost effective and flexible metallic UF-NPFs for functional applications. | Yuan-Yun Zhao Feng Qian Chengliang Zhao Chunxiao Xie Jianguo Wang Chuntao Chang Yanjun Li Lai-Chang Zhang | 2021 | Journal of Materials Science & Technology2021，，11： | 0 |
| 7 | Identification and characterization of extrachromosomal circular DNA in the silk gland of Bombyx mori显示文摘The silk gland cells of silkworm are special cells which only replicate DNA in the nucleus without cell division throughout the larval stage. The extrachromosomal circular DNAs (eccDNAs) have not yet been reported in the silk gland of silkworms. Herein, we have explored the characterization of eccDNAs in the posterior silk gland of silkworms. A total of 35 346 eccDNAs were identified with sizes ranging from 30 to 13 569 549 bp. Motif analysis revealed that dual direct repeats are flanking the 5′ and 3′ breaking points of eccDNA. The sequences exceeding 1 kb length in eccDNAs present palindromic sequence characteristics flanking the 5′ and 3′ breaking points of the eccDNA. These motifs might support possible models for eccDNA generation. Genomic annotation of the eccDNA population revealed that most eccDNAs (58.6%) were derived from intergenic regions, whereas full or partial genes were carried by 41.4% of eccDNAs. It was found that silk protein genes fib-H, fib-L, and P25, as well as the transcription factors SGF and sage, which play an important regulatory role in silk protein synthesis, could be carried by eccDNAs. Gene Ontology and Kyoto Encyclopedia of Genes and Genomes enrichment analyses showed that the genes carried by eccDNAs were mainly associated with the development and metabolism-related signaling pathways. Moreover, it was found that eccDNAfib-L could promote the transcription of fib-L gene. Overall, the results of the present study not only provide a novel perspective on the mechanism of silk gland development and silk protein synthesis but also complement previously reported genome-scale eccDNA data supporting that eccDNAs are common in eukaryotes. | Min Zhu Xinyu Tong Qunnan Qiu Jun Pan Shulin Wei Yuming Ding Yongjie Feng Xiaolong Hu Chengliang Gong | 2023 | Insect Science2023，30，6： | 0 |
| 8 | An integrative drug repositioning framework discovered a potential therapeutic agent targeting COVID-19显示文摘The global spread of severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)requires an urgent need to find effective therapeutics for the treatment of coronavirus disease 2019(COVID-19).In this study,we developed an integrative drug repositioning framework,which fully takes advantage of machine learning and statistical analysis approaches to systematically integrate and mine large-scale knowledge graph,literature and transcriptome data to discover the potential drug candidates against SARS-CoV-2.Our in silico screening followed by wet-lab validation indicated that a poly-ADP-ribose polymerase 1(PARP1)inhibitor,CVL218,currently in Phase I clinical trial,may be repurposed to treat COVID-19.Our in vitro assays revealed that CVL218 can exhibit effective inhibitory activity against SARS-CoV-2 replication without obvious cytopathic effect.In addition,we showed that CVL218 can interact with the nucleocapsid(N)protein of SARS-CoV-2 and is able to suppress the LPS-induced production of several inflammatory cytokines that are highly relevant to the prevention of immunopathology induced by SARS-CoV-2 infection. | Yiyue Ge Tingzhong Tian Suling Huang Fangping Wan Jingxin Li Shuya Li Xiaoting Wang Hui Yang Lixiang Hong Nian Wu Enming Yuan Yunan Luo Lili Cheng Chengliang Hu Yipin Lei Hantao Shu Xiaolong Feng Ziyuan Jiang Yunfu Wu Ying Chi Xiling Guo Lunbiao Cui Liang Xiao Zeng Li Chunhao Yang Zehong Miao Ligong Chen Haitao Li Hainian Zeng Dan Zhao Fengcai Zhu Xiaokun Shen Jianyang Zeng | 2021 | Signal Transduction and Targeted Therapy2021，6，5： | 0 |
| 9 | Facile synthesis of metal and alloy nanoparticles by ultrasound-assisted dealloying of metallic glasses显示文摘Metal and alloy nanoparticles synthesized by chemical reduction have attracted increasing attention due to their superior physical,chemical,and biological properties.However,most chemical synthesis processes rely on the use of harsh reducing agents and complicated chemical ingredients.Herein,we report a novel reduction-agent-free and surfactant(stabilizer)-free strategy to synthesize Cu,Ag,Au,Cu-Pt,Cu-Au,Cu-Au-Pt-Pd,and Au-Pt-Pd-Cu nanoparticles by ultrasound-assisted dealloying of Mgbased metallic glasses.The formation mechanism of the metal and alloy nanoparticles is revealed by a detailed investigation of sequential intermediate products.We demonstrate that the glass-liquid phase transition of the initially dealloying metallic glasses,together with the synergistic effect of dealloying and ultrasound-driven ligament-breakage of small enough nanoporous intermediates,play key roles in preparing the uniformly dispersed metal and alloy nanoparticles.This approach greatly simplifies the up-scaling synthesis of monometallic and bimetallic nanoparticles,and also provides a general strategy for synthesizing unprecedented multimetallic nanoparticles. | Yuan-Yun Zhao Feng Qian Wenfeng Shen Chengliang Zhao Jianguo Wang Chunxiao Xie Fengling Zhou Chuntao Chang Yanjun Li | 2021 | Journal of Materials Science & Technology2021，，23： | 0 |
| 10 | Linearized Double-Shock Approximate Riemann Solver for Augmented Linear Elastic Solid显示文摘In this work,in order to capture discontinuities correctly in linear elastic solid,augmented internal energy is defined according to the first law of thermodynamics and Hooke’s law.The non-conservative linear elastic system is then rewritten into a conservative form with the help of an augmented total energy equation.We find that the non-physical oscillations occur to the popular HLL and HLLC approximate Riemann solvers when directly applied to simulate the augmented linear elastic solid.We analyze the intrinsic reason by defining a discrepancy factor which can be used to estimate the difference of the total stress across a contact discontinuity,where it is physically required to be continuous.We discover that non-physical oscillations inevitably appear in the vicinity of the contact discontinuity if this factor is away from zero for an approximate Riemann problem solver.In order to overcome this difficulty,we propose an approximate Riemann solver based on the linearized double-shock technique.Theoretical analysis and numerical results show that in comparison to the HLL and HLLC approximate Riemann solvers,the present linearized double-shock Riemann solver can eliminate the non-physical oscillations effectively. | Zhiqiang Zeng Chengliang Feng Changsheng Yu Tiegang Liu | 2022 | Numerical Mathematics(Theory,Methods and Applications)2022，15，1： | 0 |

| 12 | Peanut-chocolate-ball-inspired construction of the interface engineering between CdS and intergrown Cd:Boosting both the photocatalytic activity and photocorrosion resistance显示文摘Interface engineering can improve the charge separation efficiency and inhibit photocorrosion is an emerging direction of developing more efficient and cost-effective photocatalytic systems.Herein,we report the sulfur-confined intimate Cd S intergrown Cd(Cd S/Cd)Ohmic junction(peanut-chocolate-ball like)for high-efficient H2production with superior anti-photocorrosion ability,which was fabricated from in-situ photoreduction of CdS intergrown Cd2SO4(OH)2(CdS/Cd2SO4(OH)2)prepared through a facile space-controlled-solvothermal method.The ratios of CdS/Cd can be effectively controlled by tunning that of CdS/Cd2SO4(OH)2which were prepared by adjusting the volume of reaction liquid and the remaining space of the reactor.Experiments investigations and density functional theory(DFT)calculations reveal that the Cd S intergrown Cd Ohmic junction interfaces(with appropriate content Cd intergrown on Cd S(19.54 wt%))are beneficial in facilitating the transfer of photogenerated electrons by constructing an interfacial electric field and forming sulfur-confined structures for preventing the positive holes(h+)oxidize the Cd S.This contributes to a high photocatalytic H2production activity of 95.40μmol h-1(about 32.3 times higher than bare Cd S)and possesses outstanding photocatalytic stability over 205 h,much longer than most Cd S-based photocatalysts previously reported.The interface engineering design inspired by the structure of peanut-chocolate-ball can greatly promote the future development of catalytic systems for wider application. | Wending Zhou Feng Li Xiangfei Yang Wanliang Yang Chun Wang Rui Cao Chengliang Zhou Mengkui Tian | 2023 | Journal of Energy Chemistry2023，，1： | 0 |
| 13 | Microscale heterogeneity of soil bacterial communities under long-term fertilizations in fluvo-aquic soils显示文摘Differently sized soil aggregates,with non-uniform distribution of space and nutrients,provide spatially heterogeneous microenvironments for microorganisms and are important for controlling microbial community ecology and biogeochemistry in soils.Here,we investigated the prokaryotic communities within different aggregate-size fractions:macroaggregate(>0.25 mm),microaggre-gate(0.053–0.25 mm)and silt+clay(<0.053 mm).These were isolated from fluvo-aquic soils under 39-year fertilization strategies:no fertilizer(CK),chemical fertilizer(NPK),manure fertilizer(M),and combination of manure and chemical fertilizers(MNPK).The results showed that the proportion of macroaggregate,soil aggregate-associated organic carbon(SOC)content and aggregate stability were all significantly increased by both manure and chemical fertilizations.Organic fertilizations(M and MNPK)more effectively boosted formation and stability of macroaggregates and enhanced SOC concentration than NPK.The distribution patterns of microorganisms in aggregates were primarily shaped by fertilization and aggregate size.They explained 76.9%of the variance in bacterial community compositions.Fertilizations,especially with organic fertilizers primarily transitioned bacterial communities from slow-growing oligotrophic groups(e.g.,Chloroflexi)dominance to fast-growing copiotrophic groups(e.g.,Proteobacteria and Bacteroidetes)dominance across all aggregate sizes.Macroaggregates possessed a more stable bacterial community and efficiency of resource transfer,while smaller aggregates increased antagonism and weakened mutualism among bacterial communities.Overall,combination of manure and chemical fertilizers was crucial for increasing SOC content and aggregation,leading to a clear shift in bacterial community structures at aggregate scale. | Haojie Feng Hong Pan Chengliang Li Yuping Zhuge | 2022 | Soil Ecology Letters2022，4，4： | 0 |
| 14 | Waves Induced by the Appearance of Single-Point Heat Source in Constant Flow显示文摘Heating or cooling one-dimensional inviscid compressible flow can be modeled by the Euler equations with energy sources.A tricky situation is the sudden appearance of a single-point energy source term.This source is discontinuous in both the time and space directions,and results in multiple discontinuous waves in the solution.We establish a mathematical model of the generalized Riemann problem of the Euler equations with source term.Based on the double CRPs coupling method proposed by the authors,we determine the wave patterns of the solution.Theoretically,we prove the existence and uniqueness of solutions to both'heat removal'problem and'heat addition'problem.Our results provide a theoretical explanation for the effect of instantaneous addition or removal of heat on the fluid. | Changsheng Yu Tiegang Liu Chengliang Feng | 2022 | Advances in Applied Mathematics and Mechanics2022，14，4： | 0 |
