| 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 | 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 |
| 3 | Simple fabrication of superhydrophobic PLA with honeycomb-like structures for high-efficiency oil-water separation显示文摘Polylactic acid(PLA) is one of the most suitable candidates for environmental pollution treatment because of its biodegradability which will not cause secondary pollution to the environment after application.However,there is still a lack of a green and facile way to prepare PLA oil-water separation materials.In this work,a water-assisted thermally induced phase separation method for the preparation of superhydrophobic PLA oil-water separation material with honeycomb-like structures is reported.The PLA material shows great ability in application and could adsorb 27.3 times oil to its own weight.In addition,it could also be applicated as a filter with excellent efficiency(50.9 m^3 m^(-2) h^(-1)). | Xiaolong Wang Yamin Pan Huan Yuan Meng Su Chunguang Shao Chuntai Liu Zhanhu Guo Changyu Shen Xianhu Liu | 2020 | Chinese Chemical Letters2020，31，2： | 7 |
| 4 | Synthesis of layered double hydroxides/graphene oxide nanocomposite as a novel high-temperature CO_2 adsorbent显示文摘In this contribution, a novel high-temperature CO2 adsorbent consisting of Mg-Al layered double hydroxide(LDH) and graphene oxide(GO)nanosheets was prepared and evaluated. The nanocomposite-type adsorbent was synthesized based on the electrostatically driven self-assembly between positively charged Mg-Al LDH single sheet and negatively charged GO monolayer. The characteristics of this novel adsorbent were investigated using XRD, FE-SEM, HRTEM, FT-IR, BET and TGA. The results showed that both the CO2 adsorption capacity and the multicycle stability of LDH were increased with the addition of GO owing to the enhanced particle dispersion and stabilization. In particular, the absolute CO2 capture capacity of LDH was increased by more than twice by adding 6.54 wt% GO as support. GO appeared to be especially effective for supporting LDH sheets. Moreover, the CO2 capture capacity of the adsorbent could be further increased by doping with 15 wt%K2CO3. This work demonstrated a new approach for the preparation of LDH-based hybrid-type adsorbents for CO2 capture. | Junya Wang Xueyi Mei Liang Huang Qianwen Zheng Yaqian Qiao Ketao Zang Shengcheng Mao Ruoyan Yang Zhang Zhang Yanshan Gao Zhanhu Guo Zhanggen Huang Qiang Wang | 2015 | Journal of Energy Chemistry2015，24，2： | 4 |
| 5 | Preparation of Mg,N-co-doped lignin adsorbents for enhanced selectivity and high adsorption capacity of As(Ⅴ) from wastewater显示文摘Among various environmental problems,water pollution has drawn more and more attention.To develop an adsorbent with enhanced selectivity and high capacity for As(V)oxyanion,a novel lignin-based adsorbent was prepared by doping with N and modifying with Mg^(2+),using thiethylenetetramine(TETA)and MgCl_(2) as the source of N and Mg^(2+),respectively.N-doped lignin(NL)shows a high selectivity for As(Ⅴ),which is further enhanced by modifying with Mg^(2+)(MNL).MNL shows an excellent reusability.The adsorption isotherms and kinetics of MNL for As(Ⅴ)follow Langmuir isotherms model and pseudo-second-order kinetics model,respectively.The adsorption of MNL for As(Ⅴ)achieved a maximum adsorption capacity of 687.46 mg g^(−1) and the equilibrium was established within 30 min.This study offers a novel idea on the recycle of the waste of paper industry and provides a new technology for As(Ⅴ)adsorption from wastewater. | Xiaofeng Shi Junmao Hong Chao Wang Sifang Kong Junhua Li Duo Pan Jing Lin Qinglong Jiang Zhanhu Guo | 2021 | Particuology2021，19，5： | 2 |

| 8 | Highly transmitted silver nanowires-SWCNTs conductive flexible film by nested density structure and aluminum-doped zinc oxide capping layer for flexible amorphous silicon solar cells显示文摘Indium tin oxide(ITO)is widely used in transparent conductive films(TCFs);however,several disadvan-tages,such as high cost and toxicity of indium,limit its applications.Therefore,it is necessary to develop other materials that can replace ITO.Silver nanowires or single walled carbon nanotubes(SWCNTs)have attracted considerable interest owing to their unique electrical,optical,and thermal stabilities,and thus,they are ideal for transparent electrodes for flexible or stretchable devices.In this study,we develop a novel architecture of composite TCFs on a polyethylene naphthalate(PEN)flexible substrate.Herein,the silver nanowires-SWCNTs films with nested density structure were fabricated through ultrasonic spraying technology by varying the spraying width.For achieving enhanced transmittance,we combined the larger irregular grids and holes with fewer nanowires stacked in the longitudinal direction,more optical chan-nels,and good carrier transport.Thereafter,aluminum-doped zinc oxide(AZO)was used as capping to the structure for enhancing the optical properties of the TCFs.The silver nanowires-SWCNTs/AZO(ASA)bilayer was obtained in the optimized architecture,which showed superior optoelectronic performance to that shown by commercial ITO with a high optical transmittance of 92%at the wavelength of 550 nm and low sheet resistance of 17/sq.In the specially structured conductive film,the significant improvement in the transmittance and uniformity of the sheet resistance was attributed to the effective nanowire junc-tion contact compared to that in ordinary structure of silver nanowires,which reduced the mean density of small clusters of nanowires.Compared with the silver nanowires-SWCNTs films,the ASA bilayer film exhibited excellent resistance to boiling,mechanical bending(10,000 cycles),and CO_(2)plasma.Moreover,the sheet resistance of ASA changed slightly after the tape tests,thereby illustrating a strong adhesion to the PEN substrate after the enclosure of AZO.Meanwhile,the AZO capping layer can enhance the op-tical transmittance between 600 and 1500 nm.In addition,the amorphous silicon photovoltaic devices with flexible ASA TCFs exhibited a power conversion efficiency(PCE)of 8.67%.After bending for 3000 times,the PCE was decreased to 8.20%,thereby demonstrating the potential of developed films to replace traditional ITO. | Shunliang Gao Xiaohui Zhao Qi Fu Tianchi Zhang Jun Zhu Fuhua Hou Jian Ni Chengjun Zhu Tiantian Li Yanlai Wang Vignesh Murugadoss Gaber A.M.Mersal Mohamed M.Ibrahim Zeinhom M.El-Bahy Mina Huang Zhanhu Guo | 2022 | Journal of Materials Science & Technology2022，，31： | 2 |

| 10 | An overview of amphoteric ion exchange membranes for vanadium redox flow batteries显示文摘Vanadium redox flow battery(VRB),as the most promising large-scale electrical energy storage units,has attracted extensive attention.Amphoteric ion exchange membrane(AIEM),as the core part of VRB,separates electrolyte on both sides of electrolytic tank and conducts H+.The AIEM with cation and anion groups possesses excellent performances,such as high ion conductivity(σ),low vanadium ion permeability(Pvn+),relative stability and low cost.However,the performance of AIEM directly depends on the chemical structure of polymers.In addition to ensuring foundational physical performance,ion selectivity of AIEM is significant since the crossover of vanadium ion with various valences may reduce the battery capacity.In this paper,AIEMs for VRB and their chemical structures as well as synthesis approaches to realize all kinds of high-performing AIEMs are reviewed.The current trend and future direction of prospective materials for the VRB separators are documented in detail as well. | Lei Liu Chao Wang Zhenfeng He Rajib Das Binbin Dong Xiaofeng Xie Zhanhu Guo | 2021 | Journal of Materials Science & Technology2021，，10： | 1 |

| 14 | In-situ constructing visible light CdS/Cd-MOF photocatalyst with enhanced photodegradation of methylene blue显示文摘Based on high specific surface area,high porosity of metal-organic frameworks(MOFs)and excellent vis-ible light response of CdS,the CdS/Cd-MOF nanocomposites were constructed by in-situ sulfurization to form CdS using Cd-MOF as precursor and the CdS loading was controlled by the dose of thioac-etamide.Under the irradiation of simulated sunlight,the degradation rate of methylene blue(MB)by 10mg MOF/CdS-6(mass ratio of MOF to thioacetamide is 6:1)was 91.9%in 100min,which was higher than that of pure Cd-MOF(62.3%)and pure CdS(67.5%).This is attributed to the larger specific surface area of the composite catalysts,which provides more active sites.Meanwhile,the loading of CdS obvi-ously broadens the light response range of Cd-MOF and improves the utilization of visible light.The Mott-Schottky model experiment shows that the formed type-Ⅱheterojunction between Cd-MOF and CdS can effectively inhibit the recombination of photogenerated electrons and holes.Meanwhile,the photocurrent intensity of MOF/CdS-6 is 8 times and 2.5 times of that of pure Cd-MOF and CdS.In addi-tion,MOF/CdS-6 showed good photocatalytic performance after five cycles,showing excellent stability and reusability. | Cheng Jing Yufei Zhang Junjie Zheng Shengsong Ge Jing Lin Duo Pan Nithesh Naik Zhanhu Guo | 2022 | Particuology2022，20，10： | 1 |

| 16 | Epoxy resin nanocomposites reinforced with ionized liquid stabilized carbon nanotubes显示文摘Epoxy resin nanocomposites reinforced with three different ionic liquid functionalized carbon nanotubes(f-CNTs)were fabricated by an in situ polymerization method.The influence of the anions on the curing process was studied through differential scanning calorimetry(DSC)and normalized Fourier transform infrared(FTIR)spectroscopy.The composition of the nanocomposites was analyzed by X-ray photoelectron spectroscopy.Two different mechanisms are proposed to explain the curing process of the neat epoxy and its composites.The electric conductivity and mechanical properties of the nanocomposites are also reported.The tensile strength was increased dramatically due to the insertion of f-CNTs.Scanning electron microsopy fracture surface analysis indicates a strong interfacial bonding between the carbon nanotubes and the polymer matrix. | Zhe Wang Xiongtao Yang Qiang Wang H.Thomas Hahn Sang-gi Lee Kun-Hong Lee Zhanhu Guo | 2011 | International Journal of Smart and Nano Materials2011，2，3： | 1 |
| 17 | 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 |

| 19 | Interface Engineered Microcellular Magnetic Conductive Polyurethane Nanocomposite Foams for Electromagnetic Interference Shielding显示文摘Lightweight microcellular polyurethane(TPU)/carbon nanotubes(CNTs)/nickel-coated CNTs(Ni@CNTs)/polymerizable ionic liquid copolymer(PIL)composite foams are prepared by non-solvent induced phase separation(NIPS).CNTs and Ni@CNTs modified by PIL provide more heterogeneous nucleation sites and inhibit the aggregation and combination of microcellular structure.Compared with TPU/CNTs,the TPU/CNTs/PIL and TPU/CNTs/Ni@CNTs/PIL composite foams with smaller microcellular structures have a high electromagnetic interference shielding effectiveness(EMI SE).The evaporate time regulates the microcellular structure,improves the conductive network of composite foams and reduces the microcellular size,which strengthens the multiple reflections of electromagnetic wave.The TPU/10CNTs/10Ni@CNTs/PIL foam exhibits slightly higher SE values(69.9 dB)compared with TPU/20CNTs/PIL foam(53.3 dB).The highest specific EMI SE of TPU/20CNTs/PIL and TPU/10CNTs/10Ni@CNTs/PIL reaches up to 187.2 and 211.5 dB/(g cm^(−3)),respectively.The polarization losses caused by interfacial polarization between TPU substrates and conductive fillers,conduction loss caused by conductive network of fillers and magnetic loss caused by Ni@CNT synergistically attenuate the microwave energy. | Guolong Sang Pei Xu Tong Yan Vignesh Murugadoss Nithesh Naik Yunsheng Ding Zhanhu Guo | 2021 | Nano-Micro Letters2021，13，10： | 1 |
