| 1 | An atomic force microscopy study of coal nanopore structure显示文摘Coal nanopore structure is an important factor in understanding the storage and migration of absorbed gas in coal. A new method for studying coal nanopore structures is proposed. This idea is based on the nano-level resolution of atomic force microscopy, which can be employed to observe the structural features of coal nanopores clearly, conduct quantitative three-dimensional measurements and obtain structural parameters. Analysis results show that coal nanopores are mainly metamorphic pores and intermolecular pores. The metamorphic pores are commonly rounded and elliptical, increasing quantitatively with the coalification degree. The forms of intermolecular pores change markedly. The average pore size of low-rank coal is bigger than high-rank coal, and the number of intermolecular pores decreases as the coal rank increases. Section analysis effectively characterizes the coal pore microstructure, bearing analysis is a vital approach to measure microporosity, and grain analysis can be employed to study the pore size distribution. Atomic force microscopy is a tool for the in-depth research of coal pore microstructure and the coal-bed methane adsorption mechanism. | YAO SuPing JIAO Kun ZHANG Ke HU WenXuan DING Hai LI MiaoChun PEI WenMing | 2011 | Chinese Science Bulletin2011，56，25： | 30 |
| 2 | GSA:Genome Sequence Archive显示文摘With the rapid development of sequencing technologies towards higher throughput and lower cost, sequence data are generated at an unprecedentedly explosive rate. To provide an efficient and easy-to-use platform for managing huge sequence data, here we present Genome Sequence Archive(GSA; http://bigd.big.ac.cn/gsa or http://gsa.big.ac.cn), a data repository for archiving raw sequence data. In compliance with data standards and structures of the International Nucleotide Sequence Database Collaboration(INSDC), GSA adopts four data objects(Bio Project, Bio Sample,Experiment, and Run) for data organization, accepts raw sequence reads produced by a variety of sequencing platforms, stores both sequence reads and metadata submitted from all over the world,and makes all these data publicly available to worldwide scientific communities. In the era of big data, GSA is not only an important complement to existing INSDC members by alleviating the increasing burdens of handling sequence data deluge, but also takes the significant responsibility for global big data archive and provides free unrestricted access to all publicly available data in support of research activities throughout the world. | Yanqing Wang Fuhai Song Junwei Zhu Sisi Zhang Yadong Yang Tingting Chen Bixia Tang Lili Dong Nan Ding Qian Zhang Zhouxian Bai Xunong Dong Huanxin Chen Mingyuan Sun Shuang Zhai Yubin Sun Lei Yu Li Lan Jingfa Xiao Xiangdong Fang Hongxing Lei Zhang Zhang Wenming Zhao | 2017 | Genomics, Proteomics & Bioinformatics2017，15，1： | 13 |
| 3 | Isotherm Equation Study of F Adsorbed from Water Solution by Fe2(SO4)3-modified Granular Activated Alumina显示文摘The adsorption equilibrium of a fluoride solution on 1-2 mm granular activated alumina modified by Fe2(SO4)3 solution was investigated.The experiments were conducted using a wide range of initial fluoride concentrations(0.5 to 180 mg·L-1 at pH~7.0) and an adsorbent dose of 1.0 g·L-1.The application of Langmuir and Freundlich adsorption isotherm models(linear and nonlinear forms) generally showed that a single Langmuir or Freundlich equation cannot fit the entire concentration gap.Experimental data on low equilibrium concentrations(0.1 to 5.0 mg·L-1) was in line with both Langmuir and Freundlich isotherm models,whereas that of high equilibrium concentrations(5.0 to 150 mg·L-1) was more in line with the Freundlich isotherm model.A new LangmuirFreundlich function was used for the entire concentration gap,as well as for low and high concentrations. | DANG Dan DING Wenming CHENG Anguo LIU Shuming ZHANG Xu | 2011 | Chinese Journal of Chemical Engineering2011，19，4： | 5 |
| 4 | High-resolution and large-size stretchable electrodes based on patterned silver nanowires composites显示文摘Electrodes based on composites of silver nanowires(AgNWs)and elastic polymers have been widely studied and applied in various stretchable electronic devices.However,due to the high aspect ratio of nanowires,the patterning of AgNW-based composite electrodes remains a huge challenge,especially for high-resolution complex circuit wiring on large-size elastic substrates.In this paper,we propose a method for preparing large-size stretchable circuit boards with high-resolution electrodes by the combination of screen printing and vacuum filtration of AgNWs/polydimethylsiloxane(PDMS)composite.The as-prepared stretchable electrodes have smooth edges with patterning resolution up to-50 μm.The conductivity of the composite electrode can be precisely controlled by varying deposition densities of AgNWs and have reached to 1.07 x 10^(4) S/cm when the deposition density was 2.0 mg/cm^(2).In addition,the uniformity of conductivity and the resistance-strain characteristics of composite electrodes were systematically evaluated with different AgNWs deposition densities.The composite electrodes have been successfully employed to construct a large-size programmable display system and an 18-channel surface electromyography(EMG)recording,showing great potentials for some strain-insensitive stretchable circuits in wearable and health-related electronic applications. | Yong Lin Qingsong Li Chen Ding Jiayi Wang Wei Yuan Zhiyuan Liu Wenming Su Zheng Cui | 2022 | Nano Research2022，15，5： | 1 |

| 7 | Improved interfacial property by small molecule ethanediamine for high performance inverted planar perovskite solar cells显示文摘We report a simple and effective method to realize desirable interfacial property for inverted planar perovskite solar cells(PSCs)by using small molecule ethanediamine for the construction of a novel polyelectrolyte hole transport material(P3CT-ED HTM).It is found that P3CT-ED can not only improve the hole transport property of P3CT-K but also improve the crystallinity of adjacent perovskite film.In addition,the introduction of ethanediamine into P3CT realigns the conduction and valence bands upwards,passivates surface defects and reduces nonradiative recombination.As a consequence,compared to P3CT-K hole transport layer(HTL)based devices,the average power conversion efficiency(PCE)is boosted from17.2% to 19.6% for the counterparts with P3CT-ED,with simultaneous enhancement in open circuit voltage and fill factor.The resultant device displays a champion PCE of 20.5% with negligible hysteresis. | Guodong Zhang Yunxin Zhang Siqi Chen Hao Chen Le Liu Wenming Ding Jinhui Wang Anyu Zhang Shuping Pang Xin Guo Lianqing Yu Tonggang Jiu | 2021 | Journal of Energy Chemistry2021，30，3： | 0 |
| 8 | Intrinsically Viscoelastic Supramolecular Conjugated Polymer toward Suppressing Coffee-Ring Effect显示文摘The rational molecular design of light-emitting conjugated polymers that inherently suppress the ubiquitous coffee-ring effect(CRE)is a great challenge and the critical bottleneck for printing displays.Herein,we describe a supramolecular route to construct an intrinsically viscoelastic rigid conjugated polymer(RCP)(PHDPF-Cz)toward avoiding the CRE without sacrificing optoelectronic properties.Theπ-πstacking interactions derived fromthe pendant carbazole(Cz)units enable PHDPF-Cz to self-assemble into criss-cross nanofibers and endow its solutionwith great viscosity.Consequently,a high-quality and continuous PHDPFCz film was obtained by impeding the transport of aggregates to the droplet edge due to outward capillary flow during evaporation,in sharp contrast to the random aggregate migration and rapid precipitation generated fromthe controlled poly[4-(6-(9H-diphenylaniline-9-yl)hexyloxy)-9,9-diphenylfluorene]-co-[5-(6-(9H-diphenylaniline-9-yl)hexyloxy)-9,9-diphenylfluorene]and poly(9,9-dioctylfluorene)solutions.Finally,an efficient random laser is also achieved based on these cross-linked films with ultrastable single-chain excitonic behavior,confirming the effectiveness of our design strategy. | Yamin Han Lubing Bai Xiang An Man Xu Chuanxin Wei Zongqiong Lin Mengna Yu Jinyi Lin Lili Sun Ning Sun Changting Wei Linghai Xie Xuehua Ding Qi Wei Chengrong Yin Chenghui Li Wenming Su Wei Huang | 2022 | CCS Chemistry2022，4，11： | 0 |
