| 1 | Vertically Aligned Silicon Carbide Nanowires/Boron Nitride Cellulose Aerogel Networks Enhanced Thermal Conductivity and Electromagnetic Absorbing of Epoxy Composites显示文摘With the innovation of microelectronics technology, the heat dissipation problem inside the device will face a severe test. In this work, cellulose aerogel(CA) with highly enhanced thermal conductivity(TC) in vertical planes was successfully obtained by constructing a vertically aligned silicon carbide nanowires(SiC NWs)/boron nitride(BN) network via the ice template-assisted strategy. The unique network structure of SiC NWs connected to BN ensures that the TC of the composite in the vertical direction reaches 2.21 W m^(-1) K^(-1) at a low hybrid filler loading of 16.69 wt%, which was increased by 890% compared to pure epoxy(EP). In addition, relying on unique porous network structure of CA, EP-based composite also showed higher TC than other comparative samples in the horizontal direction. Meanwhile, the composite exhibits good electrically insulating with a volume electrical resistivity about 2.35 × 10^(11) Ω cm and displays excellent electromagnetic wave absorption performance with a minimum reflection loss of-21.5 dB and a wide effective absorption bandwidth(<-10 dB) from 8.8 to 11.6 GHz. Therefore, this work provides a new strategy for manufacturing polymer-based composites with excellent multifunctional performances in microelectronic packaging applications. | Duo Pan Gui Yang Hala MAbo-Dief Jingwen Dong Fengmei Su Chuntai Liu Yifan Li Ben Bin Xu Vignesh Murugadoss Nithesh Naik Salah MEl-Bahy Zeinhom MEl-Bahy Minan Huang Zhanhu Guo | 2022 | Nano-Micro Letters2022，14，7： | 7 |
| 2 | Flexible conductive polymer composites for smart wearable strain sensors显示文摘Wearable strain sensors based on flexible conductive polymer composites(FCPCs)have attracted great attention due to their applications in the fields of human–machine interaction,disease diagnostics,human motion detection,and soft robotic skin.In recent decades,FCPC‐based strain sensors with high stretchability and sensitivity,short response time,and excellent stability have been developed,which are expected to be more versatile and intelligent.Smart strain sensors are required to provide wearable comfort,such as breathability,selfcooling ability,and so forth.To adapt to the harsh environment,wearable strain sensors should also be highly adaptive to protect the skin and the sensor itself.In addition,portable power supply system,multisite sensing capability,and multifunctionality are crucial for the next generation of FCPC‐based strain sensor. | Kangkang Zhou Kun Dai Chuntai Liu Changyu Shen | 2020 | SmartMat2020，1，1： | 7 |
| 3 | Ni Flower/MXene-Melamine Foam Derived 3D Magnetic/Conductive Networks for Ultra-Efficient Microwave Absorption and Infrared Stealth显示文摘The development of multifunctional and efficient electromagnetic wave absorbing materials is a challenging research hotspot.Here,the magnetized Ni flower/MXene hybrids are successfully assembled on the surface of melamine foam(MF)through electrostatic self-assembly and dip-coating adsorption process,realizing the integration of microwave absorption,infrared stealth,and flame retardant.Remarkably,the Ni/MXene-MF achieves a minimum reflection loss(RLmin)of−62.7 dB with a corresponding effective absorption bandwidth(EAB)of 6.24 GHz at 2 mm and an EAB of 6.88 GHz at 1.8 mm.Strong electromagnetic wave absorption is attributed to the three-dimensional magnetic/conductive networks,which provided excellent impedance matching,dielectric loss,magnetic loss,interface polarization,and multiple attenuations.In addition,the Ni/MXene-MF endows low density,excellent heat insulation,infrared stealth,and flame-retardant functions.This work provided a new development strategy for the design of multifunctional and efficient electromagnetic wave absorbing materials. | Haoran Cheng Yamin Pan Xin Wang Chuntai Liu Changyu Shen Dirk W.Schubert Zhanhu Guo Xianhu Liu | 2022 | Nano-Micro Letters2022，14，4： | 7 |

| 5 | A double crosslinking MXene/cellulose nanofiber layered film for improving mechanical properties and stable electromagnetic interference shielding performance显示文摘With the discovery of the two-dimensional(2D) MXene, it shows a great application potential in the field of electromagnetic interference(EMI) shielding, but the mechanical brittleness and easy oxidation of MXene limit its wide application. For this reason, a double crosslinking strategy is provided to solve the above problems in a nacre-like “brick-mortar” layered MXene/cellulose nanofiber(MXene/CNF) film.Typically, the film was firstly suffered by dopamine modification, then was further reinforced by secondary Ca^(2+)bridging, so as to obtain excellent mechanical properties and antioxidative EMI shielding performance. Comparing with the single crosslinking, the double crosslinking strategy reveals a higher efficiency in improving the mechanical property. The mechanical strength and toughness of the double crosslinking MXene/CNF film can increase to 142.2 MPa and 9.48 MJ/m^(3), respectively. More importantly, while achieving good mechanical properties, the MXene composite film still holds a very stable EMI shielding performance of more than 44.6 dB when suffering from the oxidation treatment of hightemperature annealing, showing excellent anti-oxidation ability and environment tolerance. Therefore,this work provides a universal but effective double crosslinking strategy to solve the mechanical brittleness and easy oxidation of MXene-based composites, thus showing a huge potential in flexible EMI shielding applications. | Shilu Luo Tiantian Xiang Jingwen Dong Fengmei Su Youxin Ji Chuntai Liu Yuezhan Feng | 2022 | Journal of Materials Science & Technology2022，，34： | 4 |
| 6 | Robust double-layered ANF/MXene-PEDOT:PSS Janus films with excellent multi-source driven heating and electromagnetic interference shielding properties显示文摘The strategy of incorporating polymers into MXene-based functional materials has been widely used to improve their mechanical properties,however with inevitable sacrifice of their electrical conductivity and electromagnetic interference(EMI)shielding performance.This study demonstrates a facile yet efficient layering structure design to prepare the highly robust and conductive double-layer Janus films comprised of independent aramid nanofiber(ANF)and Ti3C2Tx MXene/poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate)(PEDOT:PSS)layers.The ANF layer serves to provide good mechanical stability,whilst the MXene/PEDOT:PSS layer ensures excellent electrical conductivity.Doping PEDOT:PSS into the MXene layer enhances the interfacial bonding strength between the MXene and ANF layers and improves the hydrophobicity and water/oxidation resistance of MXene layer.The resultant ANF/MXene-PEDOT:PSS Janus film with a conductive layer thickness of 4.4μm was shown to display low sheet resistance(2.18Ω/sq),good EMI shielding effectiveness(EMI SE of 48.1 dB),high mechanical strength(155.9 MPa),and overall toughness(19.4 MJ/m^(3)).Moreover,the excellent electrical conductivity and light absorption capacity of the MXene-PEDOT:PSS conductive layer mean that these Janus films display multi-source driven heating functions,producing excellent Joule heating(382℃ at 4 V)and photothermal conversion(59.6℃ at 100 mW/m^(2))properties. | Bing Zhou Jianzhou Song Bo Wang Yuezhan Feng Chuntai Liu Changyu Shen | 2022 | Nano Research2022，15，10： | 4 |
| 7 | The effect of the rice blast resistance gene Pi36 on the expression of disease resistance-related genes显示文摘The resistance gene Pi36 confers a stable and high level of resistance against Chinese isolates of the rice blast pathogen Mag-naporthe oryzae.Quantitative real time RT-PCR was used to investigate the expression profiles of various resistance-related genes in both the Pi36/AvPi36 incompatible interactions.Among 17 members of the OsMAPK family,OsMAPK2,OsMAPK4,OsMAPK8 and OsMAPK15 were differentially expressed,as were OsWRKY30,OsWRKY32,OsWRKY64 and OsWRKY67 among the 13 OsWRKY members studied.The induction of the expression of genes from both of these families suggests that both the JA and SA pathways are involved in Pi36-mediated defence.Other genes differentially expressed included the OsbZIP transcription factors,OsNIF1 and OsNIF2,and the NPR1 homologue OsNH2,all of which were reported in the rice blast pathosystem.The in-volvement of these genes illustrates the complexity of the downstream signalling pathways involved in the Pi36/AvrPi36 interaction. | LIU XinQiong LI YuanYuan WANG LiYuan LIU XueQun WANG ChunTai WANG Ling PAN QingHua | 2010 | Chinese Science Bulletin2010，55，18： | 3 |
| 8 | Structural engineering of cathodes for improved Zn-ion batteries显示文摘Aqueous zinc-ion batteries(ZIBs) are attracting considerable attention because of their low cost,high safety and abundant anode material resources.However,the major challenge faced by aqueous ZIBs is the lack of stable and high capacity cathode materials due to their complicated reaction mechanism and slow Zn-ion transport kinetics.This study reports a unique 3 D ’flower-like’ zinc cobaltite(ZnCo_(2)O_(4-x)) with enriched oxygen vacancies as a new cathode material for aqueous ZIBs.Computational calculations reveal that the presence of oxygen vacancies significantly enhances the electronic conductivity and accelerates Zn^(2+) diffusion by providing enlarged channels.The as-fabricated batteries present an impressive specific capacity of 148.3 mAh g^(-1) at the current density of 0.05 A g^(-1),high energy(2.8 Wh kg^(-1)) and power densities(27.2 W kg^(-1)) based on the whole device,which outperform most of the reported aqueous ZIBs.Moreover,a flexible solid-state pouch cell was demonstrated,which delivers an extremely stable capacity under bending states.This work demonstrates that the performance of Zn-ion storage can be effectively enhanced by tailoring the atomic structure of cathode materials,guiding the development of low-cost and eco-friendly energy storage materials. | Jiajia Huang Yuying Li Ruikuan Xie Jianwei Li Zhihong Tian Guoliang Chai Yanwu Zhang Feili Lai Guanjie He Chuntai Liu Tianxi Liu Dan J.L.Brett | 2021 | Journal of Energy Chemistry2021，30，7： | 3 |

| 13 | Flexible Ag Microparticle/MXene-Based Film for Energy Harvesting显示文摘Ultra-thin flexible films have attracted wide attention because of their excellent ductility and potential versatility.In particular,the energy-harvesting films(EHFs)have become a research hotspot because of the indispensability of power source in various devices.However,the design and fabrication of such films that can capture or transform di erent types of energy from environments for multiple usages remains a challenge.Herein,the multifunctional flexible EHFs with e ective electro-/photo-thermal abilities are proposed by successive spraying Ag microparticles and MXene suspension between on waterborne polyurethane films,supplemented by a hot-pressing.The optimal coherent film exhibits a high electrical conductivity(1.17×10^(4)S m^(-1)),excellent Joule heating performance(121.3℃)at 2 V,and outstanding photo-thermal performance(66.2℃ within 70 s under 100 mW cm^(-1)).In addition,the EHFs-based single-electrode triboelectric nanogenerators(TENG)give short-circuit transferred charge of 38.9 nC,open circuit voltage of 114.7 V,and short circuit current of 0.82μA.More interestingly,the output voltage of TENG can be further increased via constructing the double triboelectrification layers.The comprehensive ability for harvesting various energies of the EHFs promises their potential to satisfy the corresponding requirements. | Yunpeng Jia Yamin Pan Chunfeng Wang Chuntai Liu Changyu Shen Caofeng Pan Zhanhu Guo Xianhu Liu | 2021 | Nano-Micro Letters2021，13，12： | 1 |

| 17 | Rational Design of Thermosensitive Hydrogel to Deliver Nanocrystals with Intranasal Administration for Brain Targeting in Parkinson’s Disease显示文摘Mitochondrial dysfunction is commonly detected in individuals suffering from Parkinson’s disease(PD),presenting within the form of excessive reactive oxygen species(ROS)generation as well as energy metabolism.Overcoming this dysfunction within brain tissues is an effective approach to treat PD,while unluckily,the blood-brain barrier(BBB)substantially impedes intracerebral drug delivery.In an effort to improve the delivery of efficacious therapeutic drugs to the brain,a drug delivery platform hydrogel(MAG-NCs@Gel)was designed by complexing magnolol(MAG)-nanocrystals(MAG-NCs)into the noninvasive thermosensitive poly(Nisopropylacrylamide)(PNIPAM)with self-gelation.The as-prepared MAG-NCs@Gel exhibited obvious improvements in drug solubility,the duration of residence with the nasal cavity,and the efficiency of brain targeting,respectively.Above all,continuous intranasal MAG-NCs@Gel delivery enabled MAG to cross the BBB and enter dopaminergic neurons,thereby effectively alleviating the symptoms of MPTP-induced PD.Taking advantage of the lower critical solution temperature(LCST)behavior of this delivery platform increases its viscoelasticity in nasal cavity,thus improving the efficiency of MAG-NCs transit across the BBB.As such,MAG-NCs@Gel represented an effective delivery platform capable of normalizing ROS and adenosine triphosphate(ATP)in the mitochondria of dopaminergic neurons,consequently reversing the mitochondrial dysfunction and enhancing the behavioral skills of PD mice without adversely affecting normal tissues. | Yun Tan Yao Liu Yujing Liu Rui Ma Jingshan Luo Huijie Hong Xiaojia Chen Shengpeng Wang Chuntai Liu Yi Zhang Tongkai Chen | 2021 | Research2021，，1： | 1 |

| 19 | Present and future of functionalized Cu current collectors for stabilizing lithium metal anodes显示文摘Li metal has been recognized as the most promising anode materials for next-generation high-energy-density batteries,however,the inherent issues of dendrite growth and huge volume fluctuations upon Li plating/stripping normally result in fast capacity fading and safety concerns.Functionalized Cu current collectors have so far exhibited significant regulatory effects on stabilizing Li metal anodes(LMAs),and hold a great practical potential owing to their easy fabrication,low-cost and good compatibility with the existing battery technology.In this review,a comprehensive overview of Cu-based current collectors,including planar modified Cu foil,3D architectured Cu foil and nanostructured 3D Cu substrates,for Li metal batteries is provided.Particularly,the design principles and strategies of functionalized Cu current collectors associated with their functionalities in optimizing Li plating/stripping behaviors are discussed.Finally,the critical issues where there is incomplete understanding and the future research directions of Cu current collectors in practical LMAs are also prospected.This review may shed light on the critical understanding of current collector engineering for high-energy-density Li metal batteries. | Yuhang Liu Yifan Li Jinmeng Sun Zhuzhu Du Xiaoqi Hu Jingxuan Bi Chuntai Liu Wei Ai Qingyu Yan | 2023 | Nano Research Energy2023，2，1： | 1 |
| 20 | Advancing the pressure sensing performance of conductive CNT/PDMS composite film by constructing a hierarchical-structured surface显示文摘Flexible pressure sensors have attracted wide attention due to their applications to electronic skin,health monitoring,and human-machine interaction.However,the tradeoff between their high sensitivity and wide response range remains a challenge.Inspired by human skin,we select commercial silicon carbide sandpaper as a template to fabricate carbon nanotube(CNT)/polydimethylsiloxane(PDMS)composite film with a hierarchical structured surface(h-CNT/PDMS)through solution blending and blade coating and then assemble the h-CNT/PDMS composite film with interdigitated electrodes and polyurethane(PU)scotch tape to obtain an h-CNT/PDMS-based flexible pressure sensor.Based on in-situ optical images and finite element analysis,the significant compressive contact effect between the hierarchical structured surface of h-CNT/PDMS and the interdigitated electrode leads to enhanced pressure sensitivity and a wider response range(0.1661 kPa^(-1),0.4574 kPa^(-1)and 0.0989 kPa^(-1)in the pressure range of 0–18 kPa,18–133 kPa and 133–300 kPa)compared with planar CNT/PDMS composite film(0.0066 kPa^(-1)in the pressure range of 0–240 kPa).The prepared pressure sensor displays rapid response/recovery time,excellent stability,durability,and stable response to different loading modes(bending and torsion).In addition,our pressure sensor can be utilized to accurately monitor and discriminate various stimuli ranging from human motions to pressure magnitude and spatial distribution.This study supplies important guidance for the fabrication of flexible pressure sensors with superior sensing performance in next-generation wearable electronic devices. | Ye Zhao Taoyu Shen Minyue Zhang Rui Yin Yanjun Zheng Hu Liu Hongling Sun Chuntai Liu Changyu Shen | 2023 | Nano Materials Science2023，5，4： | 1 |
