| 1 | In vivo self-assembled small RNAs as a new generation of RNAi therapeutics显示文摘RNAi therapy has undergone two stages of development,direct injection of synthetic siRNAs and delivery with artificial vehicles or conjugated ligands;both have not solved the problem of efficient in vivo siRNA delivery.Here,we present a proof-of-principle strategy that reprogrammes host liver with genetic circuits to direct the synthesis and self-assembly of siRNAs into secretory exosomes and facilitate the in vivo delivery of siRNAs through circulating exosomes.By combination of different genetic circuit modules,in vivo assembled siRNAs are systematically distributed to multiple tissues or targeted to specific tissues(e.g.,brain),inducing potent target gene silencing in these tissues.The therapeutic value of our strategy is demonstrated by programmed silencing of critical targets associated with various diseases,including EGFR/KRAS in lung cancer,EGFR/TNC in glioblastoma and PTP1B in obesity.Overall,our strategy represents a next generation RNAi therapeutics,which makes RNAi therapy feasible. | Zheng Fu Xiang Zhang Xinyan Zhou Uzair Ur-Rehman Mengchao Yu Hongwei Liang Hongyuan Guo Xu Guo Yan Kong Yuanyuan Su Yangyang Ye Xiuting Hu Wei Cheng Jinrong Wu Yanbo Wang Yayun Gu Sheng-feng Lu Dianqing Wu Ke Zen Jing Li Chao Yan Chen-Yu Zhang Xi Chen | 2021 | Cell Research2021，31，6： | 10 |
| 2 | Catalysis under shell: Improved CO oxidation reaction confined in Pt@h-BN core-shell nanoreactors显示文摘Core-shell nanostructures consisting of active metal cores and protective shells often exhibit enhanced catalytic performance, in which reactants can access a small part of the core surfaces through the pores in the shells. In this study, we show that Pt nanoparticles (NPs) can be embedded into few-layer hexagonal boron nitride (h-BN) overlayers, forming Pt@h-BN core-shell nanocatalysts. The h-BN shells not only protect the Pt NPs under harsh conditions but also allow gaseous molecules such as CO and O2 to access a large part of the Pt surfaces through a facile intercalation process. As a result, the Pt@h-BN nanostructures act as nanoreactors, and CO oxidation reactions with improved activity, selectivity, and stability occur at the core-shell interfaces. The confinement effect exerted by the h-BN shells promotes the Pt-catalyzed reactions. Our work suggests that two-dimensional shells can function as robust but flexible covers on nanocatalyst surfaces and tune the surface reactivity. | Mengmeng Sun Qiang Fu Lijun Gao Yanping Zheng Yangyang Li Mingshu Chen Xinhe Bao | 2017 | Nano Research2017，10，4： | 5 |
| 3 | Effect of Enzyme-assisted Refining on the Properties of Bleached Softwood Pulp显示文摘Enzymatic pretreatment of pulp is demonstrated to be potentially effective for decreasing the energy consumption in the refining process.Herein,a neutral cellulase was utilized for the pretreatment of bleached softwood pulp in order to improve the refining performance.Cellulase pretreatment effectively improved the drainability of the pulp and could thus reduce the energy consumption in the refining process.The beating degree of the pulp was significantly improved at 6000 PFI revolutions,at which a maximum increase of 70% could be obtained.The water retention value(WRV) of the pulp increased by 17% after treatment with cellulase at a dosage of 5 IU/g,and the fibers could be easily torn apart after enzymatic treatment.To achieve the same beating degree,the refining time could be shortened by 80% when the pulp was treated with cellulase.Using a low dosage of cellulase,the freeness of the pulp increased rapidly without deterioration of the mechanical properties. | YangYang Peng Hao Liu ShiYu Fu XinLiang Li | 2018 | Paper And Biomaterials2018，3，3： | 4 |
| 4 | Effect of Acetic Acid Prehydrolysis on Unbleached Bamboo Pulp Production显示文摘Bamboo was used as raw material for unbleached pulp production.An acetic acid prehydrolysis process was employed before the pulping process.The effect of acetic acid prehydrolysis on pulp properties was investigated.The results showed that some components,such as hemicellulose and extractives,were degraded or dissolved in the prehydrolysis process prior to kraft pulping.SEM images of the substrate after treatment indicated that the parenchyma cell wall was thinner,and the size of pores between fiber bundle cell walls was larger.The pulping results showed that acetic acid prehydrolysis could improve the pulp quality and make the pulp easier to bleach.The brightness of the pulp reached 59.6%ISO with a single oxygen delignification step.The acetic acid prehydrolysis decreased pulp viscosity and fiber length,but not significantly.The amount of parenchyma cells in the pulp was reduced,which was beneficial for papermaking and improving mechanical strength of paper.This procedure has good potential for unbleached pulp production. | YangYang Peng ChenYin Chen Ying Wang ShiYu Fu | 2018 | Paper And Biomaterials2018，3，3： | 3 |
| 5 | In-situ microstructural investigations of the TRIP-to-TWIP evolution in Ti-Mo-Zr alloys as a function of Zr concentration显示文摘Aiming at overcoming the strength-ductility trade-off in structural Ti-alloys,a new family of TRIP/TWIP Ti-alloys was developed in the past decade(TWIP:twinning-induced plasticity;TRIP:transformationinduced plasticity).Herein,we study the tunable nature of deformation mechanisms with various TWIP and TRIP contributions by fine adjustment of the Zr content on ternary Ti-12 Mo-xZr(x=3,6,10)alloys.The microstructure and deformation mechanisms of the Ti-Mo-Zr alloys are explored by using in-situ electron backscatter diffraction(EBSD)and transmission electron microscopy(TEM).The results show that a transition of the dominant deformation mode occurred,going from TRIP to TWIP major mechanism with increasing Zr content.In the Ti-12 Mo-3 Zr alloy,the stress-induced martensitic transformation(SIM)is the major deformation mode which accommodates the plastic flow.Regarding the Ti-12 Mo-6 Zr alloy,the combined deformation twinning(DT)and SIM modes both contribute to the overall plasticity with enhanced strain-hardening rate and subsequent large uniform ductility.Further increase of the Zr content in Ti-12 Mo-10 Zr alloy leads to an improved yield stress involving single DT mode as a dominant deformation mechanism throughout the plastic regime.In the present work,a set of comprehensive in-situ and ex-situ microstructural investigations clarify the evolution of deformation microstructures during tensile loading and unloading processes. | Bingnan Qian Jinyong Zhang Yangyang Fu Fan Sun Yuan Wu Jun Cheng Philippe Vermaut Frederic Prima | 2021 | Journal of Materials Science & Technology2021，，6： | 2 |
| 6 | Sources of organic matter and paleo-environmental implications inferred from carbon isotope compositions of lacustrine sediments at Inexpressible Island, Ross Sea, Antarctica显示文摘The carbon isotopic composition of organic matter(δ^(13)C_(org)) was determined in two sediment cores(IIL1 and IIL9) recovered from Inexpressible Island, Ross Sea, Antarctica, and analyzed to identify the sources of that organic matter. The δ^(13)C_(org) values of sediments of IIL9 were found to vary between-14.6‰ and-11.6‰, with a mean of-13.4‰(n=48). These values were significantly higher than those of IIL1 sediments which varied between-23.2‰ and-20.4‰, with a mean of-21.8‰(n=55). The variation in δ^(13)C_(org) values in these two sediment cores indicate different sources of organic matter. The relatively high δ^(13)C_(org) values in IIL9 are in accordance with a source from algae, while the low δ^(13)C_(org) values in IIL1 evince significant influence from penguin guano with algae as the secondary source. Compared with the reference data from other high-latitude lake sediments and plants, the δ^(13)C_(org) values in IIL9 were extremely high, a result likely related to intense competition for CO_2 assimilation among algal species during the growing season in this relatively shallow pond. These results indicate that sedimentary δ^(13)C_(org) is a reliable proxy for paleo-primary productivity in ponds at Inexpressible Island. | WEI Yangyang JIN Jing NIE Yaguang CHEN Xin WU Libin FU Pingqing LIU Xiaodong Steven D.Emslie | 2016 | Advances in Polar Science2016，27，4： | 2 |
| 7 | CHD3 chromatin-remodeling factor PICKLE regulates floral transition partially via modulating LEAFY expression at the chromatin level in Arabidopsis显示文摘PICKLE(PKL), a putative CHD3 chromatin remodeling factor, has been suggested to be involved in multiple processes in Arabidopsis. Here, we confirmed the late-flowering phenotype caused by pkl mutation with pkl mutants in two different ecotypes, and investigated the possible mechanisms that account for PKL regulation of flowering time. Quantitative RT-PCR and RNA-seq assays showed that expression of the LEAFY gene(LFY) and a number of LFY-regulated floral homeotic genes were down-regulated in seedlings of the pkl mutants. As predicted, overexpression of LFY restored normal flowering time of pkl mutants. Our results suggest that PKL may be involved in regulating flowering time via LFY expression. To uncover the underlying mechanism, Ch IP-PCR using anti-PKL was performed on materials from three developmental stages of seedlings. Our results showed that PKL associated with the genomic sequences of LFY, particularly at 10-day and 25-day after germination. We also showed that loss of PKL affected H3K27me3 level at the promoter of LFY. Taken together, our data suggest that transcriptional regulation of LFY at the chromatin level by PKL may at least partially account for the late-flowering phenotype of pkl mutants. | Xing Fu Chaonan Li Qing Liang Yangyang Zhou Hang He Liu-Min Fan | 2016 | Science China(Life Sciences)2016，59，5： | 2 |
| 8 | Effect of photoionisation on initial discharge in air under nanosecond pulse voltage显示文摘Effects of photoionisation on the development and electron runaway of the initial discharge in atmospheric air under nanosecond pulse voltage were studied via twodimensional particle-in-cell/Monte Carlo collision simulations.It was found that photoionisation has little effect at the beginning of the initial discharge.However,as the discharge channel gradually develops towards the anode,photoionisation shows greater impacts on the morphology of discharge but has little influence on the velocity of discharge development.Photoionisation does not appear to have a decisive effect on the growth trend of the highest energy of runaway electrons,but it does affect the change rate of the highest energy and overall distribution of electron energy,resulting in a higher proportion of energetic electrons.The difference in the distributions of the electron energy between the two cases,with and without considering photoionisation,can be attributed to the impact of photoionisation on the discharge morphology,which in turn distorted the electric field.The spatial density distributions of the electrons produced by photoionisation further explained the differences.The authors’results explicitly demonstrate the influence of photoionisation on the development and the electron runaway of the initial discharge under nanosecond pulse voltage,which provides more comprehensive knowledge for the atmospheric air gap nanosecond pulse discharge physics. | Yutai Li Yangyang Fu Zhigang Liu Handong Li Peng Wang Haiyun Luo Xiaobing Zou Xinxin Wang | 2023 | High Voltage2023，8，2： | 2 |
| 9 | Regulating the Function of Nanocomposite Made from Hydroxypropyl Methyl Cellulose with Bacterial Cellulose Nanocrystal显示文摘Hydroxypropyl methyl cellulose(HPMC)-based hybrid nanocomposites reinforced with bacterial cellulose nanocrystals(BCNC) were prepared and characterized.The HPMC nanocomposites exhibited good thermal stability,with a thermogravimetric peak temperature of around 346℃.The addition of BCNC did not significantly affect the thermal degradation temperature or improve the transparency of HPMC nanocomposites.However,the addition of BCNC favorably affected the light scattering properties of the nanocomposites and enhanced mechanical properties such as tensile stress and Young's modulus from 65 MPa and 1.5 GPa up to 139 MPa and 3.2 GPa,respectively.The oxygen permeability of the HPMC nanocomposites also increased with increase in the amount of BCNC added. | AiJing Zhou YangYang Peng ShiYu Fu Hao Liu | 2016 | Paper And Biomaterials2016，1，2： | 2 |
| 10 | Identification and Physical Mapping of New PCR-Based Markers Specific for the Long Arm of Rye(Secale cereale L.) Chromosome 6显示文摘To effectively use elite genes on the long arm of rye chromosome 6(the 6RL arm) in wheat breeding programs,precise and fast identification of 6RL chromatin in wheat backgrounds is necessary.PCR-based 6RL-specific markers can facilitate the detection of elite genes on 6RL in wheat breeding.However,only a limited number of 6RL-specific markers have been developed.In the present study.300 new PCR-based 6RL-specific markers were identified using specific length amplified fragment sequencing(SLAF-seq) technology,and were further physically mapped to four regions on the 6RL arm using 6R and 6RL deletion lines.Interestingly,127 of the 300 markers were physically localized to a region from the site between 2.3 and 2.5 to the telomere,the same region where the powdery mildew resistance gene was mapped.In addition,95 of the 300 markers exhibit polymorphisms,which can be used to investigate the diversity of rye 6RL arms.The markers developed in this study can be used to identify given segments of 6RL in wheat backgrounds and accelerate the utilization of elite genes on 6RL in wheat breeding. | Meng Li Zongxiang Tang Ling Qiu Yangyang Wang Shuyao Tang Shulan Fu | 2016 | Journal of Genetics and Genomics2016，43，4： | 2 |
| 11 | Spatial transcriptome analysis of long non-coding RNAs reveals tissue specificity and functional roles in cancer显示文摘Long non-coding RNAs(lncRNAs)play a significant role in maintaining tissue morphology and functions,and their precise regulatory effectiveness is closely related to expression patterns.However,the spatial expression patterns of lncRNAs in humans are poorly characterized.Here,we constructed five comprehensive transcriptomic atlases of human lncRNAs covering thousands of major tissue samples in normal and disease states.The lncRNA transcriptomes exhibited high consistency within the same tissues across resources,and even higher complexity in specialized tissues.Tissue-elevated(TE)lncRNAs were identified in each resource and robust TE lncRNAs were refined by integrative analysis.We detected 1 to 4684 robust TE lncRNAs across tissues;the highest number was in testis tissue,followed by brain tissue.Functional analyses of TE lncRNAs indicated important roles in corresponding tissue-related pathways.Moreover,we found that the expression features of robust TE lncRNAs made them be effective biomarkers to distinguish tissues;TE lncRNAs also tended to be associated with cancer,and exhibited differential expression or were correlated with patient survival.In summary,spatial classification of lncRNAs is the starting point for elucidating the function of lncRNAs in both maintenance of tissue morphology and progress of tissue-constricted diseases. | Kang XU Xiyun JIN Ya LUO Haozhe ZOU Dezhong LV Liping WANG Limei FU Yangyang CAI Tingting SHAO Yongsheng LI Juan XU | 2023 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2023，24，1： | 1 |
| 12 | Hierarchical macro-microporous WPU-ECM scaffolds combined with Microfracture Promote in Situ Articular Cartilage Regeneration in Rabbits显示文摘Tissue engineering provides a promising avenue for treating cartilage defects.However,great challenges remain in the development of structurally and functionally optimized scaffolds for cartilage repair and regeneration.In this study,decellularized cartilage extracellular matrix(ECM)and waterborne polyurethane(WPU)were employed to construct WPU and WPU-ECM scaffolds by water-based 3D printing using low-temperature deposition manufacturing(LDM)system,which combines rapid deposition manufacturing with phase separation techniques.The scaffolds successfully achieved hierarchical macro-microporous structures.After adding ECM,WPU scaffolds were markedly optimized in terms of porosity,hydrophilia and bioactive components.Moreover,the optimized WPU-ECM scaffolds were found to be more suitable for cell distribution,adhesion,and proliferation than the WPU scaffolds.Most importantly,the WPU-ECM scaffold could facilitate the production of glycosaminoglycan(GAG)and collagen and the upregulation of cartilage-specific genes.These results indicated that the WPU-ECM scaffold with hierarchical macro-microporous structures could recreate a favorable microenvironment for cell adhesion,proliferation,differentiation,and ECM production.In vivo studies further revealed that the hierarchical macro-microporous WPU-ECM scaffold combined with the microfracture procedure successfully regenerated hyaline cartilage in a rabbit model.Six months after implantation,the repaired cartilage showed a similar histological structure and mechanical performance to that of normal cartilage.In conclusion,the hierarchical macro-microporous WPU-ECM scaffold may be a promising candidate for cartilage tissue engineering applications in the future. | Mingxue Chen YangYang Li Shuyun Liu Zhaoxuan Feng Hao Wang Dejin Yang Weimin Guo Zhiguo Yuan Shuang Gao Yu Zhang Kangkang Zha Bo Huang Fu Wei Xinyu Sang Qinyu Tian Xuan Yang Xiang sui Yixin Zhou Yufeng Zheng Quanyi Guo | 2021 | Bioactive Materials2021，6，7： | 1 |

| 14 | Similarity of gas discharge in low-pressure argon gaps between two plane-parallel electrodes显示文摘The similarity of gas discharge in low-pressure argon gaps between two plane-parallel electrodes was investigated by experiments,numerical simulations and theoretical analysis.It was found by the experiments that the breakdown voltages depend not only on the product of gas pressure and gap length,but also on the aspect ratio of the gap,i.e.U_(b)=f(pd,d/r).It was theoretically proved that U_(b)=f(pd,d/r)is also a special case,the non-uniform electric field between plane-parallel electrodes,of similarity theorem of gas discharge.It was found by the experiments that there exist similar glow discharges only in two gaps with a limited scaled-down factor k.By theoretical analysis,it was explained that the forbidden processes such as the stepwise ionisation and the inelastic collision of the second kind violate the similarity of discharge as k increases,which was verified by the numerical simulations of the discharges with or without these two forbidden processes taken into account. | Yangyang Fu Shuo Yang Xiaobing Zou Haiyun Luo Xinxin Wang | 2016 | High Voltage2016，1，2： | 1 |
| 15 | Statistical properties of kinetic-scale magnetic holes in terrestrial space显示文摘Kinetic-scale magnetic holes(KSMHs)are structures characterized by a significant magnetic depression with a length scale on the order of the proton gyroradius.These structures have been investigated in recent studies in near-Earth space,and found to be closely related to energy conversion and particle acceleration,wave-particle interactions,magnetic reconnection,and turbulence at the kineticscale.However,there are still several major issues of the KSMHs that need further study—including(a)the source of these structures(locally generated in near-Earth space,or carried by the solar wind),(b)the environmental conditions leading to their generation,and(c)their spatio-temporal characteristics.In this study,KSMHs in near-Earth space are investigated statistically using data from the Magnetospheric Multiscale mission.Approximately 200,000 events were observed from September 2015 to March 2020.Occurrence rates of such structures in the solar wind,magnetosheath,and magnetotail were obtained.We find that KSMHs occur in the magnetosheath at rates far above their occurrence in the solar wind.This indicates that most of the structures are generated locally in the magnetosheath,rather than advected with the solar wind.Moreover,KSMHs occur in the downstream region of the quasi-parallel shock at rates significantly higher than in the downstream region of the quasi-perpendicular shock,indicating a relationship with the turbulent plasma environment.Close to the magnetopause,we find that the depths of KSMHs decrease as their temporal-scale increases.We also find that the spatial-scales of the KSMHs near the subsolar magnetosheath are smaller than those in the flanks.Furthermore,their global distribution shows a significant dawn-dusk asymmetry(duskside dominating)in the magnetotail. | ShuTao Yao ZongShun Yue QuanQi Shi Alexander William Degeling HuiShan Fu AnMin Tian Hui Zhang Andrew Vu RuiLong Guo ZhongHua Yao Ji Liu Qiu-Gang Zong XuZhi Zhou JingHuan Li WenYa Li HongQiao Hu YangYang Liu WeiJie Sun | 2021 | Earth and Planetary Physics2021，5，1： | 1 |
| 16 | Do corticosteroids have a role in treating Ebola virus disease?显示文摘Dear Editor,Humans have been fighting Ebola virus disease(EVD)since its first outbreak in 1976 in Yambuku village in the Democratic Republic of the Congo(previously Zaire).EVD is part of the Filoviridae family of viruses that includes Ebola and Marburg viruses.To date,EVD,one of the most deadly communicable diseases known to humans,has had15 outbreaks in Africa.In 2014,the most severe and complicated outbreak yet swept through the West African countries of Guinea,Liberia,Nigeria,Senegal and Sierra Leone, | XU Jun TAN DingYu FU YangYang WALLINE Joseph YU XueZhong | 2015 | Science China(Life Sciences)2015，58，1： | 1 |
| 17 | Effect of Zn content on microstructure,mechanical properties and thermal conductivity of extruded Mg-Zn-Ca-Mn alloys显示文摘Mg-Zn-Ca-Mn series alloys are developed as promising candidates of 5G communication devices with excellent thermal conductivities,great ductility,and acceptable strength.In present paper,Mg-x Zn-0.4Ca-0.2Mn(x=2wt%,4wt%,6wt%)alloys were prepared by a near-solidus extrusion and the effect of Zn content on mechanical and thermal properties were investigated.The results showed that the addition of minor Ca led to the formation of Ca_(2)Mg_(6)Zn_(3) eutectic phase at grain boundaries.A type of bimodal microstructure occurred in the as-extruded alloys,where elongated coarse deformed grains were embedded in refined recrystallized grains matrix.Correspondingly,both yield strength and ductility of the alloys were significantly enhanced after extrusion due to the great grain refinement.Specially,higher Zn content led to the increment in yield strength and a slight reduction in elongation due to the larger fractions of second phase particles.The room temperature thermal conductivity of as-extruded alloys was also improved compared with that of as-cast counterparts.The increment of Zn content decreased the thermal conductivity of both as-cast and as-extruded alloys,which was due to the increased second phase fraction and solution atoms in the matrix,that hindering the motion of electrons.The as-extruded Mg-2Zn-0.4Ca-0.2Mn(wt%)alloy exhibited the highest elongation of 27.7% and thermal conductivity of 139.2 W/(m·K),combined with an acceptable ultimate tensile strength of 244.0 MPa.The present paper provides scientific guidance for the preparation of lightweight materials with high ductility and high thermal conductivity. | Bei Tang Jinlong Fu Jingkai Feng Xiting Zhong Yangyang Guo Haili Wang | 2023 | International Journal of Minerals,Metallurgy and Materials2023，30，12： | 0 |
| 18 | Accurate quantification of 3'-terminal 2'-O-methylated small RNAs by utilizing oxidative deep sequencing and stem-loop RT-qPCR显示文摘The continuing discoveries of novel classes of RNA modifications in various organisms have raised the need for improving sensitive,convenient,and reliable methods for quantifying RNA modifications.In particular,a subset of small RNAs,including microRNAs(miRNAs)and Piwi-interacting RNAs(piRNAs),are modified at their 3'-terminal nucleotides via 2'-0-methylation.However,quantifying the levels of these small RNAs is difficult because 2'-0-methylation at the RNA 3'-terminus inhibits the activity of polyadenylate polymerase and T4 RNA ligase.These two enzymes are indispensable for RNA labeling or ligation in conventional miRNA quantification assays.In this study,we profiled 3'-terminal 2'-0-methyl plant miRNAs in the livers of rice-fed mice by oxidative deep sequencing and detected increasing amounts of plant miRNAs with prolonged oxidation treatment.We further compared the efficiency of stem-loop and poly(A)-tailed RT-qPCR in quantifying plant miRNAs in animal tissues and identified stem-loop RT-qPCR as the only suitable approach.Likewise,stem-loop RT-qPCR was superior to poly(A)-tailed RT-qPCR in quantifying 3'-terminal 2'-0-methyl piRNAs in human seminal plasma.In summary,this study established a standard procedure for quantifying the levels of 3'-terminal 2'-0-methyl miRNAs in plants and piRNAs.Accurate measurement of the 3'-terminal 2'-0-methylation of small RNAs has profound implications for understanding their pathophysiologic roles in biological systems. | Yan Kong Huanhuan Hu Yangyang Shan Zhen Zhou Ke Zen Yulu Sun Rong Yang Zheng Fu Xi Chen | 2022 | Frontiers of Medicine2022，16，2： | 0 |
| 19 | Impact of greenhouse gas CO_(2) on the heterogeneous reaction of SO_(2) on alpha-Al_(2)O_(3)显示文摘The heterogeneous reaction of SO_(2) on mineral dust surfaces is generally considered as an important chemical pathway for secondary sulfate formation in the troposphere.To this day,there are no reported studies that assess the impact of atmospheric CO_(2) in sulfate production on mineral dust surfaces.In this work,we investigate the impact of CO_(2) on SO_(2) uptake on dust proxy aluminum oxide particles using a diffuse reflectance infrared Fourier transform spectroscopy(DRIFTS).CO_(2) is demonstrated to suppress the heterogeneous oxidation of SO_(2) on alpha-Al2 O_(3).Compared to that measured in the CO_(2)-free case,the uptake coefficient is decreased by nearly 57%when Al_(2)O_(3) particles are exposed to the gas flow with atmospheric CO_(2) at a relative humidity(RH)of 25%.It is also found that there is a balance between the yield of active moiety-OH provided by AI(OH)3(CO)(OH)2 clusters and the loss of basic hydroxyl group on aluminum oxide surfaces blocked by CO_(2)-derived(bi)carbonate species.This work,for the first time,reveals a negative effect of atmospheric CO_(2) on the sulfate formation,which potentially decreases solarradiation scattering and further exacerbates global warming. | Yangyang Liu Tao Wang Xiaozhong Fang Yue Deng Hanyun Cheng Hongbo Fu Liwu Zhang | 2020 | Chinese Chemical Letters2020，31，10： | 0 |
| 20 | Compressive deformation-induced hierarchical microstructure in a TWIPβTi-alloy显示文摘The deformation mode of{332}<113>twinning(hereafter called 332T)has often been observed under the plastic flow in metastableβtitanium alloys with body-centered cubic(BCC)structure,which contributes to improving the mechanical performance.Herein,we report a structure of compressive deformation-induced primary 332T with hierarchical and/or heterogeneous composite sub-structure in a Twin-Induced Plasticity(TWIP)βTi-alloy under uniaxial compression.The detailed structural characterization after compressive deformation revealed that the sub-structure,including secondary 332T and secondary{112}<111>twinning,formed inside the 332T structure,which constitutes a hierarchical and/or heterogeneous structure at micro-and nano-scale and consequently contributes to the high strength,large ductility and enhanced strain-hardening behavior. | Jinyong Zhang Bingnan Qian Wang Lin Ping Zhang Yijin Wu Yangyang Fu Yu Fan Zheng Chen Jun Cheng Jinshan Li Yuan Wu Yu Wang Fan Sun | 2022 | Journal of Materials Science & Technology2022，，17： | 0 |
