| 1 | Flexible and transparent graphene/silver-nanowires composite ?lm for high electromagnetic interference shielding effectiveness显示文摘Herein, an efficient approach to prepare flexible, transparent, and lightweight films based on graphene nanosheets(GNS) and silver nanowires(AgNWs) for high electromagnetic interference(EMI) shielding effectiveness(SE) has been explained. High-conductive GNS were fabricated by liquid phase stripping and composited with AgNWs by a two-step spin-coating method. Owing to the high transparency, good conductivity, and homogeneous distribution of both GNS and AgNWs, the obtained GNS/AgNWs film exhibits superb EMI SE and light transmittance, yielding a significantly high EMI SE up to 26 dB in both Ku-band and K-band and light transmittance higher than 78.4%. Moreover, this GNS/AgNWs film shows good flexibility and excellent structural stability. The obtained flexible, light and transparent film could have a great potential for transparent EMI shielding and smart electronics. | Ning Zhang Zhe Wang Rongguo Song Qianlong Wang Hongye Chen Bin Zhang Haifei Lv Zhi Wu Daping He | 2019 | Science Bulletin2019，64，8： | 12 |
| 2 | Enhanced methane production in an anaerobic digestion and microbial electrolysis cell coupled system with co-cultivation of Geobacter and Methanosarcina显示文摘The anaerobic digestion(AD)and microbial electrolysis cell(MEC)coupled system has been proved to be a promising process for biomethane production.In this paper,it was found that by co-cultivating Geobacter with Methanosarcina in an AD–MEC coupled system,methane yield was further increased by 24.1%,achieving to 360.2 m L/g-COD,which was comparable to the theoretical methane yield of an anaerobic digester.With the presence of Geobacter,the maximum chemical oxygen demand(COD)removal rate(216.8 mg COD/(L·hr))and current density(304.3 A/m_3)were both increased by 1.3 and 1.8 fold compared to the previous study without Geobacter,resulting in overall energy efficiency reaching up to 74.6%.Community analysis demonstrated that Geobacter and Methanosarcina could coexist together in the biofilm,and the electrochemical activities of both were confirmed by cyclic voltammetry.Our study observed that the carbon dioxide content in total gas generated from the AD reactor with Geobacter was only half of that generated from the same reactor without Geobacter,suggesting that Methanosarcina may obtain the electron transferred from Geobacter for the reduction of carbon dioxide to methane.Taken together,Geobacter not only can improve the performance of the MEC system,but also can enhance methane production. | Qi Yin Xiaoyu Zhu Guoqiang Zhan Tao Bo Yanfei Yang Yong Tao Xiaohong He Daping Li Zhiying Yan | 2016 | Journal of Environmental Sciences2016，28，4： | 9 |
| 3 | ZIF-8/LiFePO4 derived Fe-N-P Co-doped carbon nanotube encapsulated Fe2P nanoparticles for efficient oxygen reduction and Zn-air batteries显示文摘Iron-based oxygen reduction reaction(ORR)catalysts have been the focus of research,and iron sources play an important role for the preparation of efficient ORR catalysts.Here,we successfully use LiFePO4 as ideal sources of Fe and P to construct the heteroatom doped Fe-based carbon materials.The obtained Fe-N-P co-doped coral-like carbon nanotube arrays encapsulated Fe2P catalyst(C-ZIF/LFP)shows very high half-wave potential of 0.88 V in alkaline electrolytes toward ORR,superior to Pt/C(0.85 V),and also presents a high half-wave potential of 0.74 V in acidic electrolytes,comparable to Pt/C(0.8 V).When further applied into a home-made Zn-air battery as cathode,a peak power density of 140 mW·cm^-2 is reached,exceeds commercial Pt/C(110 mW·cm^-2).Besides,it also presents exceptional durability and methanol resistance compared with Pt/C.Noticeably,the preparation method of such a high-performance catalyst is simple and easy to optimize,suitable for the large-scale production.What’s more,it opens up a more sustainable development scenario to reduce the hazardous wastes such as LiFePO4 by directly using them for preparing high-performance ORR catalysts. | Huihui Jin Huang Zhou Pengxia Ji Chengtian Zhang Jiahuan Luo Weihao Zeng Chenxi Hu Daping He Shichun Mu | 2020 | Nano Research2020，13，3： | 8 |
| 4 | Highly sensitive wearable sensor based on a flexible multi-layer graphene film antenna显示文摘The use of advanced carbon nanomaterials for flexible antenna sensors has attracted great attention due to their outstanding electromechanical properties. However, carbon nanomaterial based composites have yet to overcome drawbacks, such as low conductivity and toughness. In this work, a flexible multi-layer graphene film(FGF) with a high conductivity of 10~6 S/m for antenna based wearable sensors is investigated. A 1.63 GHz FGF antenna sensor exhibits significantly high strain sensitivity of 9.8 for compressive bending and 9.36 for tensile bending, which is super than the copper antenna sensor(5.39 for compressive bending and 4.05 for tensile bending). Moreover, the FGF antenna sensor shows very good mechanical flexibility, reversible deformability and structure stability, and thus is well suited for applications like wearable devices and wireless strain sensing. | Danli Tang Qianlong Wang Zhe Wang Quantao Liu Bin Zhang Daping He Zhi Wu Shichun Mu | 2018 | Science Bulletin2018，63，9： | 7 |
| 5 | Design Engineering,Synthesis Protocols,and Energy Applications of MOF-Derived Electrocatalysts显示文摘The core reactions for fuel cells,rechargeable metal-air batteries,and hydrogen fuel production are the oxygen reduction reaction(ORR),oxygen evolution reaction(OER),and hydrogen evolution reaction(HER),which are heavily dependent on the efficiency of electrocatalysts.Enormous attempts have previously been devoted in non-noble electrocatalysts born out of metal-organic frameworks(MOFs)for ORR,OER,and HER applications,due to the following advantageous reasons:(i)The significant porosity eases the electrolyte diffusion;(ii)the supreme catalyst-electrolyte contact area enhances the diffusion efficiency;and(iii)the electronic conductivity can be extensively increased owing to the unique construction block subunits for MOFs-derived electrocatalysis.Herein,the recent progress of MOFs-derived electrocatalysts including synthesis protocols,design engineering,DFT calculations roles,and energy applications is discussed and reviewed.It can be concluded that the elevated ORR,OER,and HER performances are attributed to an advantageously well-designed high-porosity structure,significant surface area,and plentiful active centers.Furthermore,the perspectives of MOF-derived electrocatalysts for the ORR,OER,and HER are presented. | Amr Radwan Huihui Jin Daping He Shichun Mu | 2021 | Nano-Micro Letters2021，13，9： | 4 |
| 6 | Effect of organic carbon on nitrification effciency and community composition of nitrifying biofilms显示文摘The effects of organic carbon/inorganic nitrogen(C/N) ratio on the nitrification processes and the community shifts of nitrifying biofilms were investigated by kinetic comparison and denaturing gradient gel electrophoresis(DGGE) analysis.The results showed that the nitrification rate decreased with an increasing organic concentration.However,the effect became weak when the carbon concentration reached a suffciently high level.Denitrification was detected after organic carbon was added.The 12 h ammonium removal rate ranged from 85% to 30% at C/N = 0.5,1,2,4,8,and 16,as compared to the control(C/N = 0).The loss of nitrogen after 24 h at C/N = 0.5,1,2,4,8,and 16 was 31%,18%,24%,65%,59%,and 62%,respectively.The sequence analysis of 16S rRNA gene fragments revealed that the dominant populations changed from nitrifying bacteria(Nitrosomonas europaea and Nitrobacter sp.) to denitrifying bacteria(Pseudomonas sp.,Acidovorax sp.and Comamonas sp.) with an increasing C/N ratio.Although at high C/N ratio the denitrifying bacteria were the dominant populations,nitrifying bacteria grew simultaneously.Consequently,nitrification process coexisted with denitrification. | HU Jie LI Daping LIU Qiang TAO Yong HE Xiaohong WANG Xiaomei LI Xudong GAO Ping | 2009 | Journal of Environmental Sciences2009，21，3： | 3 |
| 7 | Central role of myeloid MCPIP1 in protecting against LPSinduced inflammation and lung injury显示文摘Although systemic inflammatory responses attributable to infection may lead to significant lung injury,the precise molecular mechanisms leading to lung damage are poorly understood and therapeutic options remain limited.Here,we show that myeloid monocyte chemotactic protein-inducible protein 1(MCPIP1)plays a central role in protecting against LPS-induced inflammation and lung injury.Myeloid-specific MCPIP1 knockout mice developed spontaneous inflammatory syndromes,but at a late age compared to global MCPIP1 knockout mice.Moreover,mice with a myeloid-specific deletion of MCPIP1 were extremely sensitive to LPS-induced lung injury due to overproduction of proinflammatory cytokines and chemokines.We identified C/EBPβand C/EBPδ,two critical transcriptional factors that drive cytokine production and lung injury,as targets of MCPIP1 RNase.LPS administration caused MCPIP1 protein degradation in the lungs.Pharmacological inhibition of MALT1,a paracaspase that cleaves MCPIP1,by MI-2 selectively increased the MCPIP1 protein levels in macrophages and in the lungs.Meanwhile,administration of MI-2 protected mice from LPS-induced inflammation,lung injury and death.Collectively,these results indicate that myeloid MCPIP1 is central in controlling LPS-induced inflammation and lung injury.Pharmacological inhibition of MALT1 protease activity may be a good strategy to treat inflammatory diseases by enhancing MCPIP1 expression in myeloid cells. | Yong Li Xuan Huang Shengping Huang Hui He Tianhua Lei Fatma Saaoud Xiao-Qiang Yu Ari Melnick Anil Kumar Christopher J Papasian Daping Fan Mingui Fu | 2017 | Signal Transduction and Targeted Therapy2017，2，1： | 2 |
| 8 | Ultra-small platinum nanoparticles segregated by nickle sites for efficient ORR and HER processes显示文摘In the electrochemical process,Pt nanoparticles(NPs)in Pt-based catalysts usually agglomerate due to Oswald ripening or lack of restraint,ultimately resulting in reduction of the active sites and catalytic efficiency.How to uniformly disperse and firmly fix Pt NPs on carbon matrix with suitable particle size for catalysis is still a big challenge.Herein,to prevent the agglomeration and shedding of Pt NPs,Ni species is introduced and are evenly dispersed in the surface of carbon matrix in the form of Ni-N-C active sites(Ni ZIF-NC).The Ni sites can be used to anchor Pt NPs,and then effectively limit the further growth and agglomeration of Pt NPs during the reaction process.Compared with commercial Pt/C catalyst,Pt@Ni ZIF-NC,with ultralow Pt loading(7 wt%)and ideal particle size(2.3 nm),not only increases the active center,but also promotes the catalysis kinetics,greatly improving the ORR and HER catalytic activity.Under acidic conditions,its half-wave potential(0.902 V)is superior to commercial Pt/C(0.861 V),and the mass activity(0.38 A per mg Pt)at 0.9 V is 4.7 times that of Pt/C(0.08 A per mg Pt).Besides,it also shows outstanding HER performance.At 20 and 30 mV,its mass activity is even 2 and 6 times that of Pt/C,respectively.Whether it is under ORR or HER conditions,it still shows excellent durability.These undoubtedly indicate the realization of dual-functional catalysts with low-Pt and high-efficiency properties. | Lvhan Liang Huihui jin Huang Zhou Bingshuai Liu Chenxi Hu Ding Chen Jiawei Zhu Zhe Wang Hai-Wen Li Suli Liu Daping He Shichun Mu | 2022 | Journal of Energy Chemistry2022，31，2： | 2 |

| 10 | A new strategy to access Co/N co-doped carbon nanotubes as oxygen reduction reaction catalysts显示文摘Carbon nanotubes(CNTs),as one-dimensional nanomaterials,show great potential in energy conversion and storage due to their efficient electrical conductivity and mass transfer.However,the security risks,time-consuming and high cost of the preparation process hinder its further application.Here,we develop that a negative pressure rather than a following gas environment can promote the generation of cobalt and nitrogen co-doped CNTs(Co/N-CNTs) by using cobalt zeolitic imidazolate framework(ZIF-67) as a precursor,in which the negative pressure plays a key role in adjusting the size of cobalt nanoparticles and stimulating the rearragement of carbon atoms for forming CNTs.Importantly,the obtained Co/N-CNTs,with high content of pyridinic nitrogen and abundant graphitized structure,exhibit superior catalytic activity for oxygen reduction reaction(ORR) with half-wave potential(E_(1/2)) of 0.85 V and durability in terms of the minimum current loss(2%) after the 30,000 s test.Our development provides a new pathway for large-scale and cost-effective preparation of metal-doped CNTs for various applications. | Bingshuai Liu Huang Zhou Huihui Jin Jiawei Zhu Zhe Wang Chenxi Hu Lvhan Liang Shichun Mu Daping He | 2021 | Chinese Chemical Letters2021，32，1： | 1 |

| 12 | Hybrid ionic/electronic interphase enabling uniform nucleation and fast diffusion kinetics for stable lithium metal anode显示文摘Lithium(Li)dendrite issue,which is usually caused by inhomogeneous Li nucleation and fragile solid electrolyte interphase(SEI),impedes the further development of high-energy Li metal batteries.However,the integrated construction of a high-stable SEI layer that can regulate uniform nucleation and facilitate fast Li-ion diffusion kinetics for Li metal anode still falls short.Herein,we designed an artificial SEI with hybrid ionic/electronic interphase to regulate Li deposition by in-situ constructing metal Co clusters embedded in LiF matrix.The generated Co and LiF both enable fast Li-ion diffusion kinetics,meanwhile,the lithiophilic properties of Co clusters can serve as Li-ion nucleation sites,thereby contributing to uniform Li nucleation and non-dendritic growth.As a result,a dendrite-free Li deposition with a low overpotential(16.1 mV)is achieved,which enables an extended lifespan over 750 h under strict conditions.The full cells with high-mass-loading LiFePO_(4)(11.5 mg/cm^(2))as cathodes exhibit a remarkable rate capacity of 84.1 mAh/g at 5 C and an improved cycling performance with a capacity retention of 96.4%after undergoing 180 cycles. | Lun Li Pengxia Ji Meng Huang Zixin Zhang Hong Wang Francis Verpoort Jinlong Yang Daping He | 2024 | Chinese Chemical Letters2024，35，2： | 0 |
| 13 | Well-structured 3D channels within GO-based membranes enable ultrafast wastewater treatment显示文摘Graphene oxide(GO)-based membranes have been widely studied for realizing efficient wastewater treatment,due to their easily functionalizeable surfaces and tunable interlayer structures.However,the irregular structure of water channels within GO-based membrane has largely confined water permeance and prevented the simultaneously improvement of purification performance.Herein,we purposely construct the well-structured three-dimensional(3D)water channels featuring regular and negatively-charged properties in the GO/SiO_(2)composite membrane via in situ close-packing assembly of SiO_(2)nanoparticles onto GO nanosheets.Such regular 3D channels can improve the water permeance to a record-high value of 33,431.5±559.9 L·m^(−2)·h−1(LMH)bar−1,which is several-fold higher than those of current state-of-the-art GO-based membranes.We further demonstrate that benefiting from negative charges on both GO and SiO2,these negatively-charged 3D channels enable the charge selectivity well toward dye in wastewater where the rejection for positive-charged and negative-charged dye molecules is 99.6%vs.7.2%,respectively.The 3D channels can also accelerate oil/water(O/W)separation process,in which the O/W permeance and oil rejection can reach 19,589.2±1,189.7 LMH bar−1 and 98.2%,respectively.The present work unveils the positive role of well-structured 3D channels on synchronizing the remarkable improvement of both water permeance and purification performance for highly efficient wastewater treatment. | Huaqiang Fu Zhe Wang Peng Li Wei Qian Zixin Zhang Xin Zhao Hao Feng Zhugen Yang Zongkui Kou Daping He | 2023 | Nano Research2023，16，2： | 0 |
| 14 | Size effect enabling additive-free MXene ink with ultrahigh conductivity for screen printing of wireless electronics显示文摘Facile preparation of additive-free inks with both high viscosity and high conductivity is critical for scalable screen printing of wireless electronics,yet very challenging.MXene materials exhibit excellent conductivity and hydrophilicity,showing great potential in the field of additive-free inks for screen printing.Here,we demonstrate the synthesis of additive-free two-dimensional(2D)titanium carbide MXene inks,and realize screen-printed MXene wireless electronics for the first time.The viscosity of MXene ink is solely regulated by tuning the size of MXene nanosheet without any additives,hence rendering the printed MXene film extremely high conductivity of 1.67×10^(5) S/m and fine printing resolution down to 0.05 mm on various flexible substrates.Moreover,radio frequency identification(RFID)tags fabricated using the additive-free MXene ink via screen printing exhibit stable antenna reading performance and superb flexibility.This article,thus offers a new route for the efficient,low-cost and pollution-free manufacture of printable electronics based on additive-free MXene inks. | Shuaishuai Chen Huaqiang Fu Yunfa Si Xueyu Liu Zhe Wang Yixue Duan Zixin Zhang Hao Feng Xin Zhao Daping He | 2023 | Nano Research2023，16，8： | 0 |
| 15 | Investigation of MXene nanosheets based radio-frequency electronics by skin depth effect显示文摘Various new conductive materials with exceptional properties are utilized for the preparation of electronic devices.Achieving ultra-high conductivity is crucial to attain excellent electrical performance.However,there is a lack of systematic research on the impact of conductor material thickness on device performance.Here,we investigate the effect of conductor thickness on power transmission and radiation in radio-frequency(RF)and microwave electronics based on MXene nanosheets material transmission lines and antennas.The MXene transmission line with thickness above the skin depth exhibits a good transmission coefficient of approximately-3 dB,and the realized gain of MXene antennas exceeds 2 dBi.Additionally,the signal transmission strength of MXene antenna with thickness above the skin depth is higher than 5-μm MXene antenna approximately 5.5 dB.Transmission lines and antennas made from MXene materials with thickness above the skin depth exhibit stable and reliable performance,which has significant implications for obtaining high-performance RF and microwave electronics based on new conductive materials. | Rongguo Song Yunfa Si Wei Qian Haoran Zu Bilei Zhou Qinglei Du Daping He Yongliang Wang | 2024 | Nano Research2024，17，4： | 0 |
| 16 | Scalable fabrication of graphene-assembled multifunctional electrode with efficient electrochemical detection of dopamine and glucose显示文摘Conventional glassy carbon electrodes(GCE)cannot meet the requirements of future electrodes for wider use due to low conductivity,high cost,non-portability,lack of flexibility.Therefore,cost-effective and wearable electrode enabling rapid and versatile molecule detection is becoming important,especially with the ever-increasing demand for health monitoring and point-ofcare diagnosis.Graphene is considered as an ideal electrode due to its excellent physicochemical properties.Here,we prepare graphene film with ultra-high conductivity and customize the 3-electrode system via a facile and highly controllable laser engraving approach.Benefiting from the ultra-high conductivity(5.65×10^(5)S·m^(−1)),the 3-electrode system can be used as multifunctional electrode for direct detection of dopamine(DA)and enzyme-based detection of glucose without further metal deposition.The dynamic ranges from 1–200μM to 0.5–8.0 mM were observed for DA and glucose,respectively,with a limit of detection(LOD)of 0.6μM and 0.41 mM.Overall,the excellent target detection capability caused by the ultra-high conductivity and ease modification of graphene films,together with their superb mechanical properties and ease of mass-produced,provides clear potential not only for replacing GCE for various electrochemical studies but also for the development of portable and highperformance electrochemical wearable medical devices. | Xiaodong Ji Xin Zhao Zixin Zhang Yunfa Si Wei Qian Huaqiang Fu Zibo Chen Zhe Wang Huihui Jin Zhugen Yang Daping He | 2023 | Nano Research2023，16，5： | 0 |
