| 1 | Direct transformation of FGD gypsum to calcium sulfate hemihydrate whiskers:Preparation,simulations,and process analysis显示文摘Calcium sulfate hemihydrate(CSH) whiskers were synthesized by phase transition in CaCl_2 solution under atmospheric pressure.Analytical-grade calcium sulfate dihydrate(AR CSD) was used as the raw material for the synthesis of CSH whiskers,according to orthogonal experiments.The effects of reaction temperature,AR CSD content,H_2SO_4 content,and reaction time were investigated,and the crystallization conditions were optimized.The as-prepared CSH whiskers displayed a regular morphology and a highly uniform size,with an aspect ratio of 105.A simulation system was also established by blending various sulfates with AR CSD,to evaluate the effects of impurities in flue gas desulfurization(FGD) gypsum.The main aim was to prepare CSH whiskers directly from FGD gypsum,without any purification,using the optimized conditions.This is a facile potential alternative process for large-scale production of CSH whiskers using abundant FGD gypsum as source materials. | Miao Miao Xin Feng Gangling Wang Shaomei Cao Wen Shi Liyi Shi | 2015 | Particuology2015,13,2: | 31 |

| 3 | Shape and size effects of ceria nanoparticles on the impact strength of ceria/epoxy resin composites显示文摘Ceria nanoparticles with various shapes (rods, cubes, and plates) and sizes were controllably synthesized and then introduced into epoxy resin. Subsequently, we investigated correlations between the shape and size of ceria nanostructures and the mechanical performance of composites. The samples were characterized by transmission electron microscopy, scanning electron microscopy, and X-ray diffraction. Compared with commercial ceria filled composites, the composites made with morphology-controlled ceria nanos-tructures show a higher impact strength. It is found that epoxy resins made with high-aspect-ratio ceria nanorods show the highest impact strength, up to 17.27 kJ/m 2 , which is about four times that of the neat epoxy resin. | Xiaoqiang He Dengsong Zhang Hongrui Li Jianhui Fang Liyi Shi | 2011 | Particuology2011,9,1: | 7 |
| 4 | Preparation of Ultra-nano Talcum in Sand Mill and Its Application in the Polypropylene显示文摘The grinding of ultra-fine talcum powder and its application in a polypropylene (PP) matrix were investigated. Ultra-fine talcum powder was prepared by adjusting the grinding parameters of the physical milling process. The talcum powder exhibited polymodal distribution. The layered morphology of talcum particles in a horizontal sand mill was rarely damaged or destroyed. PP-talcum nanocomposites were prepared by melt blending using a twin-screw extruder. Nano talcum can be seen as a single particle, although it is not very apparent. The bending strength of talcum-filled PP was gradually increased by approximately 28%. The impact strength linearly decreased as the filler weight ratio increased. The overall maximum improvement in mechanical properties was recorded when the filler ratios increased from 15 wt% to 20 wt%. | 宋娜 ZHANG Xiaoji SHI Liyi 丁鹏 FU Yi PENG Zhihong | 2013 | Journal of Wuhan University of Technology(Materials Science)2013,28,1: | 5 |
| 5 | Ionic liquids for high performance lithium metal batteries显示文摘The pursuit of high energy density has promoted the development of high-performance lithium metal batteries.However,it faces a serious security problem.Ionic liquids have attracted great attention due to their high ionic conductivity,non-flammability,and the properties of promoting the formation of stable SEI films.Deeply understanding the problems existing in lithium metal batteries and the role of ionic liquids in them is of great significance for improving the performance of lithium metal batteries.This article reviews the effects of the molecular structure of ionic liquids on ionic conductivity,Li^(+)ion transference number,electrochemical stability window,and lithium metal anode/electrolyte interface,as well as the application of ionic liquids in Li-high voltage cathode batteries,Li-O_(2) batteries and Li-S batteries.The molecular design,composition and polymerization will be the main strategies for the future development of ionic liquid-based electrolytes for high performance lithium metal battery. | Kexin Liu Zhuyi Wang Liyi Shi Siriporn Jungsuttiwong Shuai Yuan | 2021 | Journal of Energy Chemistry2021,30,8: | 4 |
| 6 | Fabrication and electrical characteristics of flash-sintered SiO_(2)-doped ZnO-Bi_(2)O_(3)-MnO_(2) varistors显示文摘The dense ZnO-Bi_(2)O_(3)-MnO_(2)(ZBMS)varistors for x=0,1,2,3 wt% were fabricated by flash sintering method under the low temperature of 850℃ within 2 min.The sample temperature was estimated by a black body radiation model in the flash sintering process.The crystalline phase assemblage,density,microstructure,and electrical characteristics of the flash-sintered ZBMS varistors with different SiO_(2)-doped content were investigated.According to the XRD analysis,many secondary phases were detected due to the SiO_(2) doping.Meanwhile,the average grain size decrease with increasing SiO_(2)-doped content.The improved nonlinear characteristics were obtained in SiO_(2)-doped samples,which can be attributed to the ion migration and oxygen absorption induced by the doped SiO_(2).The flash-sintered ZBMS varistor ceramics for x=2 wt% exhibited excellent comprehensive electrical properties,with the nonlinear coefficient of 24.5,the threshold voltage and leakage current of 385 V·mm^(-1 )and 11.8μA,respectively. | Pai PENG Yujun DENG Jingpeng NIU Liyi SHI Yunzhu MEI Sanming DU Juan LIU Dong XU | 2020 | Journal of Advanced Ceramics2020,9,6: | 3 |
| 7 | Enhancing Photocatalytic Performance of NH 2-UIO66 by Defective Structural Engineering显示文摘NH_(2)-UIO66(NU)is a promising photocatalyst for the reduction of Cr(VI)to low-toxic Cr(III)driven by visible light under ambient conditions.However,the main limitation in this process is the ineffi cient ligand to metal charge transfer(LMCT)of photo-excited electrons,which is caused by inherent energy gap(ΔE_(LMCT)).This study synthesized the defective NU(NUXH,where X is the molar equivalent of the modulator)with reducedΔE_(LMCT)through linkers removal via acid treatment.The electronic structure of NUX-H was systematically investigated,and the results indicated that the structural defects in NUX-H strongly altered the environment of the Zr atoms.Furthermore,they substantially lowered the energy of the unoccupied d orbitals(LUMO),which was benefi cial to effi cient LMCT,resulting in an improved photocatalytic activity of NUX-H toward high-concentration(100 mg/L)Cr(VI)reduction.Compared to NU with defect-free structure,the reducing rate of Cr(VI)was increased by 47 times.This work introduced an alternative strategy in terms of designing effi cient photocatalysts for reducing Cr(VI)under ambient conditions. | Zhenmin Xu Jiazhen Cao Xiang Chen Liyi Shi Zhenfeng Bian | 2021 | Transactions of Tianjin University2021,27,2: | 2 |
| 8 | Advances of high-performance LiNi_(1-x-y)Co_(x)M_(y)O_(2) cathode materials and their precursor particles via co-precipitation process显示文摘Layered LiNi_(1-x-y)Co_(x)M_(y)O_(2)(M=Mn or Al)is a promising cathode material for lithium-ion batteries due to its high specific capacity and acceptable manufacturing cost.However,the polycrystalline LiNi_(1-x-y)Co_(x)M_(y)O_(2) cathode material suffers from disordered orientation of primary particles and poor geometric symmetry of secondary particles,which severely hampers the migration of Lit ions.Furthermore,the resulting anisotropy accelerates the disintegration of the secondary particle structure,significantly affecting the electrochemical performance of the polycrystalline cathode.In spite of less grain boundary,the single-crystal LiNi_(1-x-y)Co_(x)M_(y)O_(2) cathodes still suffer from severe microcracks generated by repeated planar gliding during cycling,which poses a great challenge to the cycling stability of single-crystal materials.It's worth noting that the microstructure of the cathode material is mainly inherited from its precursor.Therefore,it is necessary to deeply understand the influence of the microstructure of Ni_(1-x-y)Co_(x)M_(y)(OH)2 on the electrochemical properties of LiNi_(1-x-y)Co_(x)M_(y)O_(2) cathode materials,so as to optimize the production process of preparing high-performance cathode precursors.In this review,we summarize recent advances in the research and development of Ni-rich cathode precursor materials.Firstly,the challenges faced by the Ni-rich hydroxide precursor materials are presented,including the effect of primary particle morphology and arrangement on the electrochemical performance of cathode materials,the influence of secondary particle morphology on lithium insertion reactions in cathode,and the effect of particle size on the microcracking of single-crystal particles.Secondly,the presentation of the conventional co-precipitation reactor,the mechanism of precursor particle growth,and the influence of coprecipitation parameters are described in detail.Finally,the strategies are systematically discussed to solve the challenges of hydroxide precursors,such as the innovation and optimization on reactants,synthesis processes,and reaction equipment.To obtain satisfactory high-quality precursor materials,future work will require an in-depth understanding of the reaction mechanism,combined with simulation techniques such as flow field theory calculations to guide the synthesis of precursors.This review provides a comprehensive analysis of the current progresses on the producing technologies of highperformance cathode precursors and offers prospects for future industry developments. | Wenbiao Liang Yin Zhao Liyi Shi Zhuyi Wang Yi Wang Meihong Zhang Shuai Yuan | 2024 | Particuology2024,86,3: | 1 |

| 12 | Facile synthesis of Er^(3+)/Tm^(3+)co-doped magnetic/luminescent nanosystems for possible bioimaging and therapy applications显示文摘Manganese-zinc ferrite is a kind of very important magnetic ferrite material.The properties of wide absorption band,sensitivity to ultraviolet(UV)light and tumor H_(2)O_(2) promise it to be possibly used as a photothermal therapy(PTT),photodynamic therapy(PDT)and chemodynamic therapy(CDT)agent.Based on the unique advantages of rare-earth doped nanoparticles,an Er^(3+),Tm^(3+)co-doped upconversion-mediated nanosystem with manganese-zinc ferrite shell(named as UCNPS@M)was developed through a facile thermal co-decomposition method.The final nanosystems were surface-modified by using dopamine hydrochloride(DA)in order to warrant good biocompatibility(named as UCNPS@M@DA).Under irradiation of near-infrared(NIR)light,UCNPS emit both ultraviolet and visible light.The UV light is mostly abso rbed by manga nese-zinc ferrite shell to produce reactive oxygen species(ROS),which is essential to the potential PDT and CDT effect of nanosystems,and at the same time,Mn_(0.5)Zn_(0.5)Fe2O_(4) can further react with H_(2)O_(2) to promote the efficiency of OH-generation.It is expected that UCNPS@M@DA can act as upconversion luminescence imaging guidance due to the visible emission from UCNPS.In addition,the energy absorbed by the nanosystems can be transferred to heat to realize photothermal effect.Moreover,UCNPS@M@DA was successfully applied as a T_(1)/T_(2)-weighted magnetic resonance imaging(MRI)contrast agent due to the existence of Gd,Mn,and Fe elements.In light of the upconversion luminescence(UCL)imaging from the UCNPS as well as potential PTT,PDT,CDT effect mentioned above,this work provides a possibility to realize cancer multi-model bioimaging guided treatment by using an all-in-one diagnosis and therapy nanosystem through a simple yet powerful strategy. | Hongyu Liu Jiabei Li Pengfei Hu Songqiang Sun Liyi Shi Lining Sun | 2022 | Journal of Rare Earths2022,40,1: | 1 |

| 20 | Template/surfactant free and UV light irradiation assisted fabrication of Mn-Co oxides composite nanorings: Structure and synthesis mechanism显示文摘A facile, green, cost effective, and template or surfactant free strategy via a two-step route i.e. UV irradiation followed by dissolution-growth for the controlled synthesis of Mn-Co composite nanorings at room temperature was proposed. The nanorings structures and the process were systematically studied via TEM, HRTEM, EDX and XRD. Bir-MnO2 nanosheets first formed through the direct photolysis of KMnO4 under UV light irradiation. This was followed by a dissolution-growth process via the dissolution of Bir-MnO2 nanosheets by the generated H+ from the redox reaction between the added Co(NO3)2 and residual KMnO4, as well as the accompanied formation of CoOOH, and Mn-Co composite nanorings. It was found that a balance between the dissolution and growth rate was needed. Suitable pH, KMnO4 presence and the starting nanosheets like Bir-MnO2 were the key factors for the formation of nanorings. The obtained Mn-Co nanorings/TiO2 showed enhanced efficiency for the catalytic oxidation of HCHO. Based on the above understandings, it is believed that the developed dissolution-growth method can be adopted for the designing and preparation of other Mn-Co composite nanostructures which can be further applied for environmental pollution remediation. | Wentao Jiang Xiaonan Hu Muhammad Yaseen Liyi Shi Dengsong Zhang Jianping Zhang Lei Huang | 2019 | Progress in Natural Science:Materials International2019,29,2: | 1 |
