| 1 | Microstructure and composition engineering Yb single-filled CoSb_(3) for high thermoelectric and mechanical performances显示文摘A broad tunability of the thermoelectric and mechanical properties of CoSb_(3) has been demonstrated by adjusting the composition with the addition of an increasing number of elements.However,such a strategy may negatively impact processing repeatability and composition control.In this work,singleelement-filled skutterudite is engineered to have high thermoelectric and mechanical performances.Increased Yb filling fraction is found to increase phonon scattering,whereas cryogenic grinding contributes additional microstructural scattering.A peak zT of 1.55 and an average zT of about 1.09,which is comparable to the reported results of multiple-filled SKDs,are realized by the combination of simple composition and microstructure engineering.Furthermore,the mechanical properties of Yb single-filled CoSb_(3) skutterudite are improved by manipulation of the microstructure through cryogenic grinding.These findings highlight the realistic prospect of producing high-performance thermoelectric materials with reduced compositional complexity. | Zhenxing Zhou Matthias T.Agne Qihao Zhang Shun Wan Qingfeng Song Qing Xu Xiaofang Lu Shijia Gu Yuchi Fan Wan Jiang Gerald Jeffrey Snyder Lianjun Wang | 2019 | Journal of Materiomics2019，5，4： | 4 |
| 2 | Porous N-doped Ni@SiO_(2)/graphene network: Three-dimensional hierarchical architecture for strong and broad electromagnetic wave absorption显示文摘Electromagnetic wave absorber is critical for reducing increasingly serious electromagnetic wave pollu-tion,however,the development of lightweight and broadband microwave absorbers remains a pressing challenge.We report here the rational design and synthesis of N-doped Ni@SiO_(2)/graphene composite con-structed from 3D interconnected porous graphene network and Ni@SiO_(2) core-shell architecture,which fulfills lightweight and broadband requirements while exhibiting highly efficient electromagnetic wave absorption.The porous graphene network,functioning both as lightweight support and dielectric medi-ator,was synthesized via NaCl template-assisted high-temperature calcination method.Upon uniformly attached with core-shell Ni@SiO_(2) on the surface,the resulting abundant heterogeneous interfaces con-structed by graphene-Ni and Ni-SiO_(2) strongly reinforce polarization loss.The presence of low dielectric SiO_(2) allows facile tuning of the complex permittivity of ternary composite by adjusting coating thick-ness to balance the attenuation ability and impedance matching.Moreover,further N-doping of graphene assists in the optimization of dielectric loss ability.Taking account of the advantages arising from the porous hierarchical architecture,multiple absorption centers and diverse interfaces,the lightweight com-posite exhibits an ultra-strong reflection loss(RL)value of-71.13 dB at 13.76 GHz with a thickness of 2.46 mm and broad effective absorption bandwidth of 7.04 GHz at a low filler content of 15 wt.%.More importantly,the effective absorption range covers 13.28 GHz(4.72-18 GHz)with the optimized thickness of 1.6-5 mm,representing 83%of the whole range of frequencies.Our results demonstrate that the novel 3D porous N-doped Ni@SiO_(2)/graphene network with hierarchical architecture is a promising candidate for high-performance electromagnetic wave absorption. | Rui Guo Qi Zheng Lianjun Wang Yuchi Fan Wan Jiang | 2022 | Journal of Materials Science & Technology2022，，11： | 3 |
| 3 | Achieving effective broadband microwave absorption with Fe_(3)O_(4)@C supraparticles显示文摘The X band(8 GHz-12 GHz)is the electromagnetic wave band emitted by most electronic instruments in our life,which will cause electromagnetic pollution harm to human health.Due to the coexistence of magnetic loss and dielectric loss,the modified Fe_(3)O_(4)-carbon-based nanomaterial exhibit strong electromagnetic(EM)wave absorptive capacity.However,there is a problem that the effective absorption bandwidth(EAB,the frequency bandwidth of reflection loss is less than-10 dB)of the X band is narrow.Increasing the EAB value of Fe_(3)O_(4)-carbon-based materials is of great significance for reducing electromagnetic pollution.Here,an emulsion-based self-assembly technique and ligand carbonization treatment have been used to construct the Fe_(3)O_(4)@C supraparticles for the evaluation of EM performance.The Fe_(3)O_(4)@C supraparticles exhibit excellent EM absorption properties,which can achieve full coverage of X band from 6.52 GHz to 12.9 GHz at a sample thickness of 3 mm.Besides,the optimum EAB value of Fe_(3)O_(4)@C supraparticles is up to 8.55 GHz from 9 to 18 GHz at a sample thickness of 2.5 mm.The Fe_(3)O_(4)@C supraparticles with superlattice structure will have potential development prospects in the application of broadband absorption. | Li Su Jiaxin Ma Fangzhou Zhang Yuchi Fan Wei Luo Lianjun Wang Wan Jiang Jianping Yang | 2021 | Journal of Materiomics2021，7，1： | 2 |
| 4 | Enhanced TE properties of Cu@Ag/Bi2Te3 nanocomposites by decoupling electrical and thermal properties显示文摘Cu@Ag/Bi2Te3 nanocomposites were prepared for the first time by ultrasonic dispersion-rapid freezedrying method combined with spark plasma sintering(SPS).By changing the content of Cu@Ag nanoparticle,we could modulate the temperature dependent thermoelectric properties.The highest ZT value can be obtained at 450 K for 1 vol%Cu@Ag/Bi2Te3,which is benefited from the decoupling of electrical and thermal properties.With the increase of electrical conductivity,the absolute value of Seebeck coefficient lifts while the thermal conductivity declines.Meanwhile,the average ZT value between 300 K and 475 K was 0.61 for 1 vol%Cu@Ag/Bi2Te3,which is much higher than that of pristine Bi2 Te3.Therefore,the decoupling effect of Cu@Ag nanoparticles incorporation could be a promising method to broaden the application of Bi2Te3 based thermoelectric materials. | Xiaofang Lu Qi Zheng Shijia Gu Rui Guo Li Su Jiancheng Wang Zhenxing Zhou Yuchi Fan Wan Jiang Lianjun Wang | 2020 | Chinese Chemical Letters2020，31，3： | 1 |

| 6 | Facile synthesis of mesoporous WO3@graphene aerogel nanocomposites for low-temperature acetone sensing显示文摘Nanocomposites constructed by combining mesoporous metal oxides and graphene have received tremendous attention in wide fields of catalysis,energy storage and conversion,gas sensing and so on.Herein,we present a facile interface-induced co-assembly process to synthesize the mesoporous W03@graphene aerogel nanocomposites(denoted as mW03@GA),in which graphene aerogel(GA) was used as a macroporous substrate,mesoporous W03 was uniformly coated on both sides of graphene sheets through a solvent evaporation-induced self-assembly(EISA) strategy using diblock copolymer poly(ethylene oxide)-b-polystyrene(PEO-b-PS) as a template.The resultant mW03@GA nanocomposites possess well-interconnected macroporous graphene networks covered by mesoporous W03 layer with a uniform pore size of 19 nm,high surface area of 167 m^2/g and large pore volume of 0.26 cm^3/g.The gas sensing performance of mW03@GA nanocomposites toward acetone and other gases was studied,showing a high selectivity and great response to acetone at low temperature of 150℃,which could be developed as a promising candidate as novel sensors for VOCs detection. | Tao Zhao Yuan Ren Guangyou Jia Yuye Zhao Yuchi Fan Jianping Yang Xin Zhang Wan Jiang Lianjun Wang Wei Luo | 2019 | Chinese Chemical Letters2019，30，12： | 1 |
| 7 | Self-organization of unimolecular micelles in beam stream for functional mesoporous metal oxide nanofibers显示文摘The use of linear amphiphilic block copolymers as templates is an important method for the preparation of mesoporous materials.However,the obtained assemblies are usually sensitive to synthetic conditions,which impedes the preparation of such mesoporous materials in certain environments.Herein,we report a universal strategy applying an amphiphilic multiarm triblock copolymer in the preparation of mesoporous metal oxide nanofibers(NFs)using one metal oxide(TiO_(2),ZrO_(2),WO_(3),CeO_(2)),or two(TiO_(2)/WO 3,TiO_(2)/ZrO_(2),TiO_(2)/CeO_(2))and three(TiO_(2)/WO_(3)/CuO)metal oxides as composites.The template consists of modified β-cyclodextrin as the center of the macromolecule which is attached sequentially to a block of polystyrene,poly(acrylic acid),and poly(ethylene oxide).Under electrospinning conditions,stable unimolecular micelles are formed and effectively co-assemble with metal ions to form fibrous nanostructures.As indicated by various characterization methods,the synthesized TiO_(2) and its derived composite NFs maintain a straight and continuous fibrous structure after calcination,and TiO_(2) NFs exhibit uniform mesopores of 10.8 nm in diameter and a large Brunauer-Emmett-Teller surface area of 143.3 m^(2)g^(−1).Benefiting from the characteristic structure,still present after modification,Pt-decorated mesoporous TiO_(2) NFs display excellent ability in the visible-light photocatalytic degradation of tetracycline,which is superior to the commercial P25 catalyst.This study reveals a promising strategy for the preparation of fibrous mesoporous metal oxides. | Chongfei Gu Xiaoshan Fan Guihua Zhu Yuchi Fan Haifeng Wang Tao Zhao Qi Xiao Yuan Fang Xiaopeng Li Wan Jiang Lianjun Wang Pengpeng Qiu Wei Luo | 2022 | Fundamental Research2022，2，5： | 1 |

| 11 | A confined micro-reactor with a movable Fe_(3) O_(4) core and a mesoporous TiO_(2) shell for a photocatalytic Fenton-like degradation of bisphenol A显示文摘Photocatalysis and Fenton process are two primary and promising advanced oxidation processes to degrade organic pollutants.However,the practical applications of single photocatalysis and Fenton process are still limited.Introducing one of them into another to form a combined photocatalytic Fentonlike system has shown great potential but still faces challenges in designing a well-tailored catalyst.Herein,a confined photocatalytic Fenton-like micro-reactor catalyst with a movable Fe_(3) O_(4) core and a mesoporous TiO_(2) shell has been constructed via a successive Stober coating strategy,followed by an ultrasound assisted etching method.The resulting micro-reactor possesses well-defined yolk-shell structures with unifo rm mesopores(~4 nm),a large Brunauer-Emmett-Teller(BET) surface area(~166.7 m^(2)/g),a high pore volume(~0.56 cm^(3)/g) and a strong magnetization(~51 emu/g),as well as tunable reactor sizes(20-90 nm).When evaluated for degrading bisphenol A under solar light in the presence of peroxymo no sulfate,the micro-reactor exhibits a superior catalytic degradation perfo rmance with a high magnetic separation efficiency and an excellent recycle ability.The outstanding performance can be attributed to its unique textual structure,which leads to a great syne rgistic effect from the photocatalytic and Fenton-like process.This study gives an important insight into the design and synthesis of an advanced micro-reactor for a combined advanced oxidation processes(AOPs). | Pengpeng Qiu Tao Zhao Xiaohang Zhu Binota Thokchom Jianping Yang Wan Jiang Lianjun Wang Yuchi Fan Xiaopeng Li Wei Luo | 2021 | Chinese Chemical Letters2021，32，4： | 1 |

| 13 | Mechanically exfoliated MoS_(2) nanoflakes for optimizing the thermoelectric performance of SrTiO_(3)-based ceramic composites显示文摘As a semiconducting material with relatively low thermal conductivity,MoS_(2) nanoflake has the potential to serve as a modulator for optimizing the performance of thermoelectric(TE)materials.However,the low yield of MoS_(2) nanoflakes prepared by conventional methods has constrained the development of MoS_(2) optimized TE materials.We propose a mechanical exfoliation method for mass production of MoS_(2) nanoflakes using attrition mill.After mixed with La and Nb co-doped SrTiO_(3)(SLNT)powder,the MoS_(2)/SLNT composites are fabricated by spark plasma sintering.It is found that the heterojunctions formed at MoS_(2)/SLNT interfaces with proper band offset can effectively scatter the low-energy electrons,resulting in enhanced Seebeck coefficient without significantly undermining the electrical conductivity.The power factor of composites is improved when the MoS_(2) content is lower than 1.5 vol%.Meanwhile,the thermal conductivity of composites is significantly decreased due to the phonon scattering induced large thermal resistance at MoS_(2)/SLNT interfaces,which is much higher than that in graphene embedded SrTiO_(3) composites.Consequently,a maximum ZT-0.24 is obtained at 800 K in 1.5 vol%MoS_(2)/SLNT composite,which is~26%higher compared with pristine matrix.This work paves the way for application of TE materials modulated by transition metal dichalcogenides. | Jilong Huang Yongping Liu Peng Yan Jie Gao Yuchi Fan Wan Jiang | 2022 | Journal of Materiomics2022，8，4： | 0 |
| 14 | Graphene controlled phase evolution in Sr-deficient Sr(Ti, Nb)O_(3) thermoelectric ceramics显示文摘Correlated phase and microstructural evolution are systematically investigated by electron microscopies in Sr-deficient Sr(Ti,Nb)O_(3)(STNO)thermoelectric ceramics incorporated with different fraction of reduced graphene oxide(RGO).It is found that while no impurity except for very few Ti_(3)O_(5) precipitates are observed in monolithic STNO,the Nb-enriched rutile TiO_(2) appears in RGO/STNO composites.With increasing RGO content,the amount of precipitates increase at first and then decrease when RGO content becomes high,which can be ascribed to the formation of local Magneli phase.In addition,the energy-dispersive X-ray spectra combined with cathodoluminescence characterization indicates that the variation of Sr deficiency experiences the opposite trend with respect to the precipitates content.These findings clearly reveal the unique reducing effect of RGO on the microstructure of doped SrTiO_(3) with Sr deficiency,which can greatly facilitate the design of perovskite based thermoelectric materials of hierarchical structure. | Jia Li Cao Wu Jilong Huang Juanjuan Xing Yuchi Fan Qingqiao Fu Ying Jiang Hui Gu | 2021 | Journal of Materiomics2021，7，2： | 0 |
| 15 | Cleaner geopolymer prepared by co-activation of gasification coal fly ash and steel slag:durability properties and economic assessment显示文摘Geopolymer is a material with high early strength.However,the insufficient durability properties,such as long-term strength,acid-base resistance,freeze-thaw resistance,leaching toxicity,thermal stability,sulfate resistance and carbonation resistance,restrain its practical application.Herein,a longterm stable geopolymer composite with high final strength(ASK1)was synthesized from shell coal gasification fly ash(SFA)and steel slag(SS).Additionally,a geopolymer composite with high early strength(ASK2)was also synthesized for comparison.The results showed that ASK1 exhibited better performance on freezing-thawing resistance,carbonization resistance and heavy metals stabilization compared to the ASK2 at long-term curing.Raising the curing temperature could accelerate the unconfined compressive strength(UCS)development at initial curing ages of 3 to 7 d.Both ASK1 and ASK2 exhibited excellent acid-base and sulfate corrosion resistance.An increase for UCS was seen under KOH solution and MgSO_(4)solution corrosion for ASK1.All leaching concentrations of heavy metals out of the two geopolymers were below the standard threshold,even after 50 freezingthawing cycles.Both ASK1 and ASK2 geopolymer concrete exhibited higher sustainability and economic efficiency than Portland cement concrete.The result of this study not only provides a suitable way for the utilization of industrial solid waste in civil and environmental engineering,but also opens a new approach to improve the long-term stabilities of the geopolymers. | Xian Zhou Xia Chen Ziling Peng Yongmen Zhou Yan Li Wang Jian Zeyu Fan Yuchi Chen | 2023 | Frontiers of Environmental Science & Engineering2023，17，12： | 0 |
| 16 | Highly aligned reduced graphene oxide in alumina composites for strengthening,toughening,and electromagnetic interference shielding显示文摘Engineering ceramics with high strength,toughness and electromagnetic interference(EMI)shielding effectiveness(SE)are highly desirable as electromagnetic protecting material in harsh environment.Herein,we show that both excellent mechanical and EMI shielding performance can be realized in alumina composites embedded with highly aligned reduced graphene oxide(RGO),which are readily prepared via sintering of core-shell structured RGO@Al_(2)O_(3)nanoplates with pressure.Compared to monolithic Al_(2)O_(3),the highly aligned RGO/Al_(2)O_(3)composites show simultaneously improved strength and toughness up to~26.1%and~60.2%,respectively.The steeply rising R-curve behavior proves the better crack tolerance in the highly aligned structure with respect to randomly oriented one.Moreover,the RGO/Al_(2)O_(3)composites also exhibit a high specific EMI SE reaching~34 dB/mm in K band,due to the reflection and highly enhanced absorption after percolation in the out-of-plane direction.These findings provide a novel strategy of designing mechanically reliable engineering ceramic for EMI shielding. | Tufail Mustafa Yongping Liu Jie Gao Peng Yan Qi Ding Yuchi Fan Wan Jiang | 2023 | Journal of Materiomics2023，9，6： | 0 |
| 17 | Realizing translucency in aluminosilicate glass at ultralow temperature via cold sintering process显示文摘Glass with high visible-light transparency is widely considered as the most important optical material,which typically requires a processing temperature higher than 1000℃.Here,we report a translucent aluminosilicate glass that can be prepared by cold sintering process(CSP)at merely 300℃.After eliminating structural pores in hexagonal faujasite(EMT)-type zeolite by heat treatment,the obtained highly active nanoparticles are consolidated to have nearly full density by adding NaOH solution as liquid aids.However,direct densification of EMT powder cannot remove the structural pores of zeolite completely,leading to an opaque compact after the CSP.It is proved that the chemical reaction between the NaOH-and zeolite-derived powders is highly beneficial to dissolution–precipitation process during sintering,leading to the ultra-low activation energy of 27.13 kJ/mol.Although the addition of 5 M NaOH solution greatly promotes the densification via the reaction with aluminosilicate powder,lower or higher concentration of solvent can deteriorate the transmittance of glass.Additionally,the CSP-prepared glass exhibits a Vickers hardness of 4.3 GPa,reaching 60%of the reported value for spark plasma sintering(SPS)-prepared sample. | Jie GAO Kangjing WANG Wei LUO Xiaowei CHENG Yuchi FAN Wan JIANG | 2022 | Journal of Advanced Ceramics2022，11，11： | 0 |
