| 1 | A promising new class of irradiation tolerant materials:Ti_2ZrHfV_(0.5)Mo_(0.2) high-entropy alloy显示文摘Recently, high-entropy alloys(HEAs) or multi-principal-element alloys with unprecedented physical,chemical, and mechanical properties, have been considered as candidate materials used in advanced reactors due to their promising irradiation resistant behavior. Here, we report a new single-phase bodycentered cubic(BCC) structured Ti_2 ZrHfV_(0.5)Mo_(0.2) HEA possessing excellent irradiation resistance, i.e.,scarcely irradiation hardening and abnormal lattice constant reduction after helium-ion irradiation,which is completely different from conventional alloys. This is the first time to report the abnormal XRD phenomenon of metallic alloys and almost no hardening after irradiation. These excellent properties make it to be a potential candidate material used as core components in next-generation nuclear reactors. The particular irradiation tolerance derives from high density lattice vacancies/defects. | Yiping Lu Hefei Huang Xuzhou Gao Cuilan Ren Jie Gao Huanzhi Zhang Shijian Zheng Qianqian Jin Yonghao Zhao Chenyang Lu Tongmin Wang Tingju Li | 2019 | Journal of Materials Science & Technology2019，35，3： | 23 |
| 2 | Research progress in ZnO single-crystal:growth, scientific understanding, and device applications显示文摘Zinc oxide,a wide band-gap semiconductor,has shown extensive potential applications in high-efficiency semiconductor photoelectronic devices,semiconductor photocatalysis,and diluted magnetic semiconductors.Due to the undisputed lattice integrity,ZnO single crystals are essential for the fabrication of high-quality ZnO-based photoelectronic devices,and also believed to be ideal research subjects for understanding the underlying mechanisms of semiconductor photocatalysis and diluted magnetic semiconductors.This review,which is organized in two main parts,introduces the recent progress in growth,basic characterization,and device development of ZnO single crystals,and some related works in our group.The first part begins from the growth of ZnO single crystal,and summarizes the fundamental and applied investigations based on ZnO single crystals.These works are composed of the fabrication of homoepitaxial ZnO-based photoelectronic devices,the research on the photocatalysis mechanism,and dilute magnetic mechanism.The second part describes the fabrication of highly thermostable n-type ZnO with high mobility and high electron concentration through intentional doping.More importantly,in this part,a conceptual approach for fabricating highly thermostable p-type ZnO materials with high mobility through an integrated three-step treatment is proposed on the basis of the preliminary research. | Feng Huang Zhang Lin Wenwen Lin Jiye Zhang Kai Ding Yonghao Wang Qinghong Zheng Zhibing Zhan Fengbo Yan Dagui Chen Peiwen Lv Xian Wang | 2014 | Chinese Science Bulletin2014，59，12： | 11 |
| 3 | Association between retinal neuronal degeneration and visual function impairment in type 2 diabetic patients without diabetic retinopathy显示文摘The changes in retinal thickness and visual function in type 2 diabetic patients without clinical evidence of diabetic retinopathy were evaluated. A total of 141 diabetic subjects without retinopathy and 158 healthy subjects were enrolled in this study. Superior macular ganglion cell complex thicknesses were significantly decreased in diabetic cases, and no significant peripapillary retinal nerve fiber layer thickness changes were observed. The contrast sensitivities at all space frequencies were significantly different between diabetic patients and controls. The mean P50 amplitude from pattern electroretinogram results was reduced significantly in the diabetic group. In the diabetic group, average superior ganglion cell complex thicknesses positively correlated with both contrast sensitivities at high spatial frequencies and P50 amplitudes. The results indicated that ganglion cell complex thickness and visual function changes could be observed in diabetic subjects before the onset of any significant diabetic retinopathy. Macular ganglion cell complex reduction occurred much earlier than peripapillary retinal nerve fiber layer thinning in diabetic patients without retinopathy. | ZHU TiePei MA Jin LI YongHao ZHANG Zheng | 2015 | Science China(Life Sciences)2015，58，6： | 11 |
| 4 | A review of the synthesis and application of zeolites from coal-based solid wastes显示文摘Zeolite derived from coal-based solid wastes(coal gangue and coal fly ash)can overcome the environmental problems caused by coal-based solid wastes and achieve valuable utilization.In this paper,the physicochemical properties of coal gangue and coal fly ash are introduced.The mechanism and application characteristics of the pretreatment processes for zeolite synthesis from coal-based solid wastes are also introduced.The synthesis processes of coal-based solid waste zeolite and their advantages and disadvantages are summarized.Furthermore,the application characteristics of various coal-based solid waste zeolites and their common application fields are illustrated.Finally,we propose an alkaline fusion-assisted supercritical hydrothermal crystallization as an efficient method for synthesizing coal-based solid waste zeolites.In addition,more attention should be given to the recycling of alkaline waste liquid and the application of coal-based solid waste zeolites in the field of volatile organic compound adsorption removal. | Xiaoyu Zhang Chunquan Li Shuilin Zheng Yonghao Di Zhiming Sun | 2022 | International Journal of Minerals,Metallurgy and Materials2022，29，1： | 10 |
| 5 | Upgrading Paper-grade Softwood Kraft Pulp to Dissolving Pulp by Cold Caustic Extraction显示文摘Cold caustic extraction has potential applications in the production of dissolving-grade pulps due to its ability to selectively remove hemicellulose from lignocellulosic materials. In this study,we demonstrate the conversion of paper-grade kraft pulp into dissolving pulp by a single-stage cold caustic extraction. Under the extraction conditions of 12 wt% NaOH lye,11% pulp consistency,a temperature of 35℃,and 2 h,a paper-grade softwood kraft pulp was purified to high-grade dissolving pulp with 97. 1% α-cellulose content,1. 2% pentosane content,and narrowed molecular weight distribution. The resulting extraction filtrate was concentrated by nano-filtration to obtain the hemicellulose content of 59. 0 g / L,while the permeate was a clear Na OH solution with 10. 9 wt% concentration. A process configuration was also proposed,integrating this cold caustic extraction process with existing pulp and paper production and multi-purpose utilization of the extraction filtrate. | Chao Tian QingXian Miao LinQiang Zheng YongHao Ni | 2016 | Paper And Biomaterials2016，1，1： | 5 |
| 6 | Diatomite supported nano zero valent iron with 3D network for peroxymonosulfate activation in efficient degradation of bisphenol A显示文摘Diatomite supported nano zero valent iron(n ZVI)catalyst(NDA)with complex network structure was prepared via a mild reduction precipitation method in this work.The pore structure and pore distribution of NDA can be regulated and controlled through adjusting the loading amount of n ZVI.In general,the nano three-dimensional network formed by n ZVI and diatomite channels greatly increase the specific surface area and pore volume of NDA,and further formed more active sites,which made NDA have better performance in activating PMS to degrade BPA than pure n ZVI.The pseudo-first-order reaction rate constant of 50-NDA(50%-n ZVI/diatomite)is almost 3 times higher than that of pure n ZVI.Besides,the electron paramagnetic resonance(EPR)and radical quenching experiments showed that the activation process was dominated by the sulfate radical(SO_(4)^(-))and hydroxyl radical(·OH)produced by Fe;oxidation.The generated electrons promote the self-decomposition of PMS to produce singlet oxygen(^(1)O_(2)),and then the valence state of iron changes to produce free radicals.In addition,the possible degradation pathway of BPA was inferred from the intermediate products identified by liquid chromatograph-mass spectrometer(LC-MS).This study provides a novel strategy for the design and preparation of three-dimensional composite catalysts derived from natural mineral. | Ye Tan Shuilin Zheng Yonghao Di Chunquan Li Runze Bian Zhiming Sun | 2021 | Journal of Materials Science & Technology2021，，36： | 4 |
| 7 | Unfolding the fast neutron spectra of a BC501A liquid scintillation detector using GRAVEL method显示文摘Accurate knowledge of the neutron energy spectra is useful in basic research and applications. The overall procedure of measuring and unfolding the fast neutron energy spectra with BC501 A liquid scintillation detector is described. The recoil proton spectrum of 241Am-Be neutrons was obtained experimentally. With the NRESP7 code, the response matrix of detector was simulated.Combining the recoil proton spectrum and response matrix, the unfolding of neutron spectra was performed by GRAVEL iterative algorithm. A MatLab program based on the GRAVEL method was developed. The continuous neutron spectrum of 241Am-Be source and monoenergetic neutron spectrum of D-T source have been unfolded successfully and are in good agreement with their standard reference spectra. The unfolded 241Am-Be spectrum are more accurate than the spectra unfolded by artificial neural networks in recent years. | CHEN YongHao CHEN XiMeng LEI JiaRong AN Li ZHANG XiaoDong SHAO JianXiong ZHENG Pu WANG XinHua | 2014 | Science China(Physics,Mechanics & Astronomy)2014，57，10： | 3 |
| 8 | The effect of large deformation and material nonlinearity on gel indentation显示文摘A gel, an aggregate of polymers with solvents, has dual attributes of solid and liquid as solvent migrates in and out of the polymer network. Indentation has recently been used to characterize the mechanical properties of gels. This paper evaluates the effects of large deformation and material nonlinearity on gel indentation through theoretical modeling and finite element analysis. It is found that large deformation significantly affects the interpretation of the experimental observations and the classical relation between indentation force and depth has limitations for large deformation. The material nonlinearity does not play a very important role on indentation experiment so that the poroelasticity is a good approximation. Based on these observations, this paper proposes an alternative approach to measure the mechanical properties of gels, namely, uniaxial compression experiment. | Zheng Duan Yonghao An Jiaping Zhang Hanqing Jiang | 2012 | Acta Mechanica Sinica2012，28，4： | 2 |

| 12 | FoxJ1 inhibits African swine fever virus replication and viral S273R protein decreases the expression of FoxJ1 to impair its antiviral effect显示文摘African swine fever(ASF)is a highly pathogenic swine infectious disease that affects domestic pigs and wild boar,which is caused by the African swine fever virus(ASFV).ASF has caused huge economic losses to the pig industry and seriously threatens global food security and livestock health.To date,there is no safe and effective commercial vaccine against ASF.Unveiling the underlying mechanisms of ASFV-host interplay is critical for developing effective vaccines and drugs against ASFV.In the present study,RNA-sequencing,RT-qPCR and Western blotting analysis revealed that the transcriptional and protein levels of the host factor FoxJ1 were significantly down-regulated in primary porcine alveolar macrophages(PAMs)infected by ASFV.RT-qPCR analysis showed that overexpression of FoxJ1 upregulated the transcription of type I interferon and interferon stimulating genes(ISGs)induced by poly(dA:dT).FoxJ1 revealed a function to positively regulate innate immune response,therefore,suppressing the replication of ASFV.In addition,Western blotting analysis indicated that FoxJ1 degraded ASFV MGF505-2R and E165R proteins through autophagy pathway.Meanwhile,RT-qPCR and Western blotting analysis showed that ASFV S273R inhibited the expression of FoxJ1.Altogether,we determined that FoxJ1 plays an antiviral role against ASFV replication,and ASFV protein impairs FoxJ1-mediated antiviral effect by degradation of FoxJ1.Our findings provide new insights into the antiviral function of FoxJ1,which might help design antiviral drugs or vaccines against ASFV infection. | Caina Ma Shasha Li Fan Yang Weijun Cao Huisheng Liu Tao Feng Keshan Zhang Zixiang Zhu Xiangtao Liu Yonghao Hu Haixue Zheng | 2022 | Virologica Sinica2022，37，3： | 1 |
| 13 | Nanocellulosic materials:research/production activities and applications显示文摘Nanocelluloses have emerged as novel materials and attracted significant interest from both academia and industry.Nanocelluloses can now be produced at pilot plant and pre-commercial scales,and even at commercial scales in some regions in the world.Successful commercial applications of nanocelluloses have entered commercial stages though their full potentials are yet to be developed.In this short communication,the applications of these nanomaterials are high-lighted,including high-volume applications(e.g.,paper,textiles),high-value applications(e.g.,aerogels and structure materials for aerospace),and novel/emerging applications(e.g.,organic light emitting diodes,photonic films).Close collaboration between industries and the academic world would facilitate the development of commercial markets for using nanocelluloses in existing/new areas. | Xingye An Dong Cheng Jing Shen Qingming Jia Zhibin He Linqiang Zheng Avik Khan Bo Sun Bitao Xiong Yonghao Ni | 2017 | Journal of Bioresources and Bioproducts2017，2，2： | 0 |
| 14 | Towards greener and more sustainable cellulose-based hand sanitizer products显示文摘More than 85%of the currently marketed hand sanitizer products are alcohol-based products,and the alcohol content is usually about 70%in order to be effective.The high alcohol content can cause dehydration,which is undesirable for sensitive skin,particularly for children.This creates opportunities for the development of innovative hand sanitizer products that are free of alcohol and have green nano-cellulose-based materials as carriers for the antibacterial agents.Good skin affinity and biocompatibility are the special features of the newly developed products,which would satisfy the need of the general public for green products. | Bo Sun Min Zhang Zhibin He Linqiang Zheng Jing Shen Yonghao Ni | 2017 | Journal of Bioresources and Bioproducts2017，2，2： | 0 |
| 15 | Functionalization of diatomite with glycine and amino silane for formaldehyde removal显示文摘Two amino-functionalized diatomite(DE)composites modified by 3-aminopropyltriethoxysilane(APTS)or glycine(GLY)(i.e.,APTS/DE and GLY/DE)were successfully synthesized via the wet chemical method for the time-and cost-efficient removal of indoor formaldehyde(HCHO).First,the optimal preparation conditions of the two composites were determined,and then their microstructures and morphologies were characterized and analyzed.Batch HCHO adsorption experiments with the two types of amino-modified DE composites were also conducted to compare their adsorption properties.Experimental results indicated that the pseudo-second-order kinetic and Langmuir isotherm models could well describe the adsorption process,and the maximum adsorption capacities of APTS/DE and GLY/DE prepared under optimal conditions at 20°C were 5.83 and 1.14 mg·g^(-1),respectively.The thermodynamic parameters of the composites indicated that the adsorption process was spontaneous and exothermic.The abundant amine groups grafted on the surface of DE were derived from the Schiff base reaction and were essential for the high-efficient adsorption performance toward HCHO. | Yonghao Di Fang Yuan Xiaotian Ning Hongwei Jia Yangyu Liu Xiangwei Zhang Chunquan Li Shuilin Zheng Zhiming Sun | 2022 | International Journal of Minerals,Metallurgy and Materials2022，29，2： | 0 |
| 16 | Learning from Spiropyrans:How to Make Further Developments of Donor-Acceptor Stenhouse Adducts显示文摘Donor-acceptor Stenhouse adducts(DASAs)as a species of novel photochromic molecules,have been developing rapidly and attracting broad researchers’sights since 2014.DASAs show visible/near-infrared(NIR)light induced linear-to-cyclic isomerization and heat induced cyclic-to-linear isomerization,therefore they are attractive in photoresponsive hydrogels,drug delivery,cell culturing and tissue engineering.As a series of well-known photoresponsive molecules,spiropyrans(SPs)show similar molecular properties and comparable photoswitching with DASAs.UV light triggers closed-to-open(also known as spirocyclic(SC)-to-merocyanine(MC))isomerization of SPs,while the reversed open-to-closed isomerization occurs under visible light or heat.Light irradiation switches the molecular color,scale,geometry,and polarity of SPs and DASAs reversibly.Since the researches on DASAs are still in the infancy,the chemical structures,isomerization mechanisms and potential applications need to be further investigated and explored.The well-studied SPs have important reference values to the comprehensive developments of DASAs.In the present review,we summarized,compared and discussed SPs and DASAs with regards to their molecular structures,synthesis,photoswitching and applications.We also make our perspective on the developments of DASA in future. | Yongli Duan Haiquan Zhao Chaoyue Xiong Lijun Mao Dongsheng Wang Yonghao Zheng | 2021 | Chinese Journal of Chemistry2021，39，4： | 0 |
| 17 | Strengthening and toughening bulk Ni_(2)CoFeV_(0.5) medium-entropy alloy via thermo-mechanical treatment显示文摘Single-phase face-centered cubic(fcc)medium-and high-entropy alloys(MEAs/HEAs)have high ductility but low yield strength.In this work,the microstructures of single-phase fcc Ni_(2)CoFeV_(0.5) MEAs were tailored by cold-rolling and subsequent annealing and typical heterogeneous lamella(HL)structures composed of recrystallized micro-grain lamellae(with an averaged grain size of∼4μm)and nonrecrystallized nano-/ultrafine-grain lamellae were obtained.Tensile tests revealed that most HL samples exhibited excellent strength and ductility synergy.The HL sample with∼23 vol%recrystallized grains annealed at 590℃ for 1 h had a high yield strength of 1120 MPa and a good fracture elongation of 12.3%,which increased by 5%and 46%,respectively compared with those of as-rolled sample.Annealing-induced yield strength increase is attributed to high-density annealing twin boundaries(TBs)in the recrystallized grains,the annihilation of mobile dislocations inside the non-recrystallized grains,and extra heterodeformation-induced strengthening produced by the HL structure.Hall-Petch relationship of Ni_(2)CoFeV_(0.5) MEA can be reasonably described by counting both TBs and grain boundaries,with lattice friction stress of 87.3 MPa and coefficient of 722.8 MPaμm1/2.Our work provides optional and controllable solutions for preparing MEAs/HEAs with excellent mechanical properties by low-cost and high-efficiency thermomechanical treatments. | Lei Gu Rui Hou Yi Liu Guang Chen Jihua Liu Gong Zheng Ruisheng Zhang Yonghao Zhao | 2023 | Journal of Materials Science & Technology2023，，20： | 0 |
| 18 | Venovenous extracorporeal membrane oxygenation for COVID-19 and influenza H1N1 associated acute respiratory distress syndrome:A comparative cohort study in China显示文摘Background Venovenous extracorporeal membrane oxygenation(VV-ECMO)has been demonstrated to be effective in treating patients with virus-induced acute respiratory distress syndrome(ARDS).However,whether the management of ECMO is different in treating H1N1 influenza and coronavirus disease 2019(COVID-19)-associated ARDS patients remains unknown.Methods This is a retrospective cohort study.We included 12 VV-ECMO-supported COVID-19 patients admitted to The First Affiliated Hospital of Guangzhou Medical University,Guangzhou Eighth People's Hospital,and Wuhan Union Hospital West Campus between January 23 and March 31,2020.We retrospectively included VV-ECMO-supported patients with COVID-19 and H1N1 influenza-associated ARDS.Clinical characteristics,respiratory mechanics including plateau pressure,driving pressure,mechanical power,ventilatory ratio(VR)and lung compliance,and outcomes were compared.Results Data from 25 patients with COVID-19(n=12)and H1N1(n=13)associated ARDS who had received ECMO support were analyzed.COVID-19 patients were older than H1N1 influenza patients(P=0.004).The partial pressure of arterial carbon dioxide(PaCO_(2))and VR before ECMO initiation were significantly higher in COVID-19 patients than in H1N1 influenza patients(P<0.001 and P=0.004,respectively).COVID-19 patients showed increased plateau and driving pressure compared with H1N1 subjects(P=0.013 and P=0.018,respectively).Patients with COVID-19 remained longer on ECMO support than did H1N1 influenza patients(P=0.015).COVID-19 patients who required ECMO support also had fewer intensive care unit and ventilator-free days than H1N1.Conclusions Compared with H1N1 influenza patients,COVID-19 patients were older and presented with increased PaCO_(2) and VR values before ECMO initiation.The differences between ARDS patients with COVID-19 and influenza on VV-ECMO detailed herein could be helpful for obtaining a better understanding of COVID-19 and for better clinical management. | Yonghao Xu Yin Xi Shuijiang Cai Yuheng Yu Sibei Chen Weijie Guan Weibo Liang Hongkai Wu Weiqun He Xilong Deng Yuanda Xu Rong Zhang Manshu Li Jieyi Pan Zhenting Liang Ya Wang Shaofeng Kong Xiaoqing Liu Zheng Lv Yimin Li | 2023 | Journal of Intensive Medicine2023，3，4： | 0 |
| 19 | Recent Advances of Stable Phenoxyl Diradicals显示文摘Organic radicals with unpaired electrons have shown great semiconducting properties with potential applications in the field of organic photodetectors,organic light-emitting diodes and organic spintronics.A major problem for limiting radicals from laboratory research to practical applications is the relatively low chemical and physical stabilities.Therefore,the right selection of radical core is the key to meaningful scientific research.Phenoxyl radical is one of the few stable radicals with spin distribution properties.Moreover,phenoxyl diradicals provide extract stability due to multiple resonance structures.Due to the long-distance spin distribution,which makes phenoxyl diradicals show interesting electronic and magnetic properties.In this review,we summarize the progress of phenoxyl diradicals in recent years in terms of syntheses,properties and future perspective. | ZHANG Hanjun MIAO Fang LIU Xiaodong WANG Dongsheng ZHENG Yonghao | 2023 | Chemical Research in Chinese Universities2023，39，2： | 0 |
| 20 | One-pot preparation and applications of self-healing,self-adhesive PAA-PDMS elastomers显示文摘A new family of transparent,biocompatible,self-adhesive,and self-healing elastomer has been developed by a convenient and efficient one-pot reaction between poly(acrylic acid)(PAA)and hydroxyl-terminated polydimethylsiloxane(PDMSOH).The condensation reaction between PAA and PDMS-OH has been confirmed by attenuated total reflection Fourier transform infrared(ATR-FTIR)spectra.The prepared PAA-PDMS elastomers possess robust mechanical strength and strong adhesiveness to human skin,and they have fast self-healing ability at room temperature(in^10 s with the efficiency of 98%).Specifically,strain sensors were fabricated by assembling PAA-PDMS as packaging layers and polyetherimide-reduced graphene oxide(PEI-rGO)as strain-sensing layers.The PAA-PDMS/PEI-rGO sensors are stably and reliably responsive to slight physical deformations,and they can be attached onto skin directly to monitor the body’s motions.Meanwhile,strain sensors can self-heal quickly and completely,and they can be reused for the motion detecting after shallowly scratching the surface.This work provides new opportunities to manufacture high performance self-adhesive and self-healing materials. | Yujin Yao Huiling Tai Dongsheng Wang Yadong Jiang Zhen Yuan Yonghao Zheng | 2019 | Journal of Semiconductors2019，40，11： | 0 |
