| 5 | Janus electrode with simultaneous management on gas and liquid transport for boosting oxygen reduction reaction显示文摘Oxygen reduction efficiency holds the key for renewable energy technologies including fuel cells and metal-air batteries,which involves coupling diffusion-reaction-conduction processes at the interface of catalyst/electrolyte,and thus rational electrode design facilitating mass transportation stands as a key issue for fast oxygen reduction reaction(ORR).Herein,we report a Janus electrode with asymmetric wettability prepared by partly modifying aerophobic nitrogen doped carbon nanotube arrays with polytetrafluoroethylene(PTFE)as a high performance catalytic electrode for ORR.The Janus electrode with opposite wettability on adjacent sides maintains stable gas reservoir in the aerophilic side while shortening O2 pathway to catalysts in the aerophobic side,resulting in superior ORR performance(22.5 mA/cm^2@0.5 V)than merely aerophilic or aerophilic electrodes.The Janus electrode endows catalytic performance even comparable to commercial,Pt/C in the alkali ne electrolyte,exploiting a previously unrecognized opport unity that guides electrode design for the gas-consumption electrocatalysis. | Yingjie Li Haichuan Zhang Nana Han Yun Kuang Junfeng Liu Wen Liu Haohong Duan Xiaoming Sun | 2019 | Nano Research2019,12,1: | 4 |
| 6 | Ternary NiCoFe-layered double hydroxide hollow polyhedrons as highly efficient electrocatalysts for oxygen evolution reaction显示文摘With exhaustion of fossil fuels and the deterioration of global environment,widespread and intensive researches have been concentrated on clean and sustainable alternative energy sources,such as metal-air batteries[1],fuel cells[2]and water splitting devices[3].Electrocatalytic oxidation of water to O2(oxygen evolution reaction,OER)is a vital chemical process involved in energy storage and conversion from renewable sources in form of molecular fuels such as H2 via water electrolysis,which has attracted a great amount of research efforts in the past few years[4,5].Nowadays,RuO2 and IrO2 are widely used as typical excellent OER electrocatalysts.However,their high-cost and scarce nature restricts the broadly commercial application of those materials[6,7].Hence,there is an urgent demand to develop low cost,highly efficient,and superb stable OER catalysts. | Yongji Qin Fanping Wang Jing Shang Muzaffar Iqbal Aijuan Han Xiaoming Sun Haijun Xu Junfeng Liu | 2020 | Journal of Energy Chemistry2020,29,4: | 4 |
| 7 | Effects of extracts from Chuanwu(Aconitum Carmichaelii) and Banxia(Rhizoma Pinelliae) on excisional wound healing in a rat's model显示文摘OBJEVTIVE: To investigate the effects of extracts from Chuanwu(Aconitum Carmichaelii) and Banxia(Rhizoma Pinelliae) on the excisional wound healing in a rat's model.METHODS: Rats were performed a surgical lesion with a 2.0 cm resected tissue in the dorsal fascia.Following, animals were randomly divided into model group, YNB group and APE group those were respectively treated with saline, 1 mg/mL of Yunnan Baiyao and 1 mg/mL of Chuanwu(Aconitum Carmichaelii) and Banxia(Rhizoma Pinelliae) extracts. Wound contractions in days 0, 3, 7, 14 and 21 were calculated by an image analyzer. Histological analysis was analyzed using hematoxilin and eosin.Levels of tumor necrosis factor-2(IL-2), IL-4, IL-10, transformαin(TNF-g growα), interleukinth factor-1(TGF-nd basic fibroblast growth factor(bFββ1) a-GF) were determined by real-time quantitative PCR.RESULTS: Compared with that of YNB group and APE gtoup, the skin of rats showed poor re-modeling and re-epithelization characterized by a significant decrease of neovascularization, epithelialization and fibroblast in the model group. In the APE group, levels of TNF-α-and IL-2 were significantly down-regulated and IL4 and IL-10 significantly upregulated in contrasted with that of model group.In addition, levels of TGF-roup were significantly iβ1 and bFGF in the APE gnduced compared with that of model group.CONCLUSION: The results suggest that the extracts from Chuanwu(Aconitum Carmichaelii) and Banxia(Rhizoma Pinelliae) promote wound healing in the rats, which is associated with enhancing antiinflammatory ability and inducing fibroblast formation. | Xia Xichao Ma Yuhong Wang Fuan Zheng Xinhua Liu Yang Zhang Junfeng Cui Juan Shi Bingqin Li Hongwen Liu Rongzhi Zhang Yaping Cheng Zhaofei Han Xiaolong | 2019 | Journal of Traditional Chinese Medicine2019,39,1: | 4 |
| 8 | Angle-dependent discoloration structures in wing scales of Morpho menelaus butterfly显示文摘The Morpho butterfly is famous for its typical structural color and has increasingly attracted the interest of scholars in a wide variety of research fields. Herein, it was found that the color of Morpho menelaus butterfly wings is not only structure-based but also viewing-angle-dependent. Firstly, the discoloration effect of this typical butterfly was confirmed by a series of experiments. Then, the general form, arrangements, and geometrical dimensions of the scales were observed using a stereomicroscope. Scanning electron microscopy was also used to examine the two-dimensional morphologies and structures of a single scale. Afterwards, one model with the optimized three-dimensional profile of the structure was described using Pro-engineer software. The associate model was then analyzed to reconstruct the process between the incident light and the model surface. Finally, the mechanism of the angle-dependent discoloration effect was analyzed by theoretical calculation and optical simulation. Different light propagation paths and the length of the incident light at different angles caused destructive or constructive interference between the light reflected from the different layers. The different spectra of the reflected light make the wings appear with different structural colors, thereby endowing the angle-dependent discoloration effect. The consistency of the calculation and simulation results confirms that these structures possess an excellent angle-dependent discoloration effect. This functional 'biomimetic structure' would not only be of great scientific interest but could also have a great impact in a wide range of applications such as reflective displays, credit card security, and military stealth technology. | NIU ShiChao LI Bo YE JunFeng MU ZhengZhi ZHANG JunQiu LIU Yan HAN ZhiWu | 2016 | Science China(Technological Sciences)2016,59,5: | 4 |
| 9 | Structural parameter optimization for novel internal-loop iron–carbon micro-electrolysis reactors using computational fluid dynamics显示文摘It is generally recognized that internal-loop reactors are well-developed mass and heat-transfer multiphase flow reactors. However, the internal flow field in the internal-loop reactor is influenced by the structure parameter of the reactor, which has a great effect on the reaction efficiency. In this study, the computational fluid dynamics simulation method was used to determine the influence of reactor structure on flow field, and a volume-offluid model was employed to simulate the gas–liquid, two-phase flow of the internal-loop micro-electrolysis reactor. Hydrodynamic factors were optimized when the height-to-diameter ratio was 4:1, diameter ratio was9:1, draft-tube axial height was 90 mm. Three-dimensional simulations for the water distributor were carried out, and the results suggested that the optimal conditions are as follows: the number of water distribution pipes was four, and an inhomogeneous water distribution was used. According to the results of the simulation,the suitable structure can be used to achieve good fluid mechanical properties, such as the good liquid circulation velocity and gas holdup, which provides a good theoretical foundation for the application of the reactor. | Lei Zhang Mengyu Wu Yanhe Han Meili Liu Junfeng Niu | 2019 | Chinese Journal of Chemical Engineering2019,27,4: | 3 |
| 10 | Flexible Multiplexing Mechanism for Coexistence of URLLC and EMBB Services in 5G Networks显示文摘5G mobile networks are envisioned to support both evolved mobile broadband(eMBB) and ultra-reliable and low latency communications (URLLC), which may coexistand interfere with each other in the same service cell in many scenarios. In this paper, wepropose a dynamic 2-dimension bitmap resource indication to cancel eMBB services witha finer uplink cancellation granularity and a lower probability of false cancellation. Meanwhile,a resource indication based power control method is introduced to dynamically indicatedifferent power control parameters to the user equipment (UE) based on differenttime-frequency resource groups and the proportion of overlapping resources, by which thereliability of URLLC transmission is guaranteed while the impact on the performance ofthe eMBB service is minimized. Furthermore, a dynamic selection mechanism is proposedto accommodate the varying cases in different scenarios. Extensive system level simulationsare conducted and the results show that about 10.54% more URLLC UE satisfy therequirements, and the perceived throughput of eMBB UE is increased by 23.26%. | XIAO Kai LIU Xing HAN Xianghui HAO Peng ZHANG Junfeng ZHOU Dong WEI Xingguang | 2021 | ZTE Communications2021,19,2: | 3 |
| 11 | Distribution Features of the Nanhua-Sinian Rifts and their Significance to Hydrocarbon Accumulation in the Tarim Basin显示文摘On the basis of reprocessing 34 new two-dimensional spliced long sections(20,191 km) in the Tarim Basin, the deep structure features of the Tarim Basin were analyzed through interpreting 30,451 km of two-dimensional seismic data and compiling basic maps. Seismic interpretation and geological analysis conclude that the Nanhua-Sinian strata are a set of rift-depression depositional systems according to their tectonic and depositional features. The rift valley formed in the Nanhua Period, and the transformation became weaker during the late Sinian Period, which eventually turned into depression. From bottom to top, the deposited strata include mafic igneous, tillite, mudstone, and dolomite. Three major depocenters developed inside this basin during the rift stage and are distributed in the eastern Tarim Basin, the Awati area, and the southwestern Tarim Basin. Among them, the rift in the eastern Tarim Basin strikes in the near east-west direction on the plane and coincides with the aeromagnetic anomaly belt. This represents a strong magnetic zone formed by upwelling basic volcanic rock along high, steep normal faults of the Nanhua Period. Controlled by the tectonic background, two types of sedimentary systems were developed in the rift stage and depression stage, showing two types of sequence features in the Sinian depositional stage. The Nanhua System appears as a wedge-shaped formation, with its bottom in unconformable contact with the base. The rifting event has a strong influence on the current tectonic units in the Tarim Basin, and affects the distribution of source rock in the Yuertus Formation and reservoir beds in the Xiaoerbulake Formation in Lower Cambrian, as well as the gypseous cap rock in Middle Cambrian. The distribution features of the rifts have important and realistic significance for determining the direction of oil and gas exploration in the deep strata of the Tarim Basin. Comprehensive analysis suggests that the Tazhong region is the most favorable zone, and the Kalpin-Bachu region is the optimal potential zone for exploring sub-salt oil and gas in deep Cambrian strata. | BAI Zhongkai CHENG Minghua CHEN Cheng HUO Junzhou ZHANG Junfeng ZHOU Xingui GAO Yongjin ZHAO Bo QIU Haijun HAN Miao YANG Youxing SUN Zhichao MIAO Miaoqing ZHANG Jinhu LI Qingyao | 2020 | Acta Geologica Sinica(English Edition)2020,94,2: | 3 |

| 14 | Original Sedimentary Pattern of an Inverted Basin:A Case Study from the Bozhong Depression,Offshore Bohai Bay Basin显示文摘The third member of Shahejie Formation(Sha-3 member; 42–38Ma of Eocene) in the Bozhong Depression,offshore Bohai Bay Basin was subject to multiple post-depositional modifications. The present structural framework of the Bozhong Depression,which is characterized by sags alternating with uplifts,does not reflect its original sedimentary pattern. Previous studies have not discussed the post-depositional modification of this succession,including the sedimentary pattern variations and the depositional geodynamic setting. This work determined the characteristics of the post-depositional modification and original sedimentary pattern of the Bozhong Depression through analysis of seismic data,well-log data and fission-track ages. The results demonstrate that the Shijiutuo rise,a major structural feature of the current basin,did not exist during the major depositional stage of the Sha-3 member,when the Qinnan sag was largely connected to the Bozhong sag to form a single contiguous deposition area within the basin. By contrast,the Shaleitian and Chengbei rises,located in the western part of the Bozhong Depression,have existed before the depositional period of the Eocene Sha-3 member; these features were manifested as syn-depositional tilted fault blocks,the uplifted footwall blocks of which provided sediments for the neighboring Shanan and Chengbei sags. The western part of the Bonan low rise,located in the southern part of the Bozhong Depression,did not experience uplifting during the depositional phase of the Eocene Sha-3 member. The Huanghekou sag was connected with the Bozhong sag in the western part of the Bozhong Depression. The original sedimentary boundary of the southern Miaoxi sag possibly extended eastward about 10 km and connected with the Bozhong sag at its northern part. The present-day Bodong low rise,which is bounded by the Tan–Lu fault zone,also formed after the depositional period of Eocene Sha-3 member. It is thus concluded that the Bozhong Depression formed a connected large-scale sub-basin during the depositional stage of the Eocene Sha-3 member. Several neighboring sags that are now separated by rises,including the Qinnan,Shanan,Chengbei,Huanghekou,Miaoxi and Bodong sags,formed a single contiguous depositional area during the Eocene. The significant differences between the present and original basin patter and framework provide valuable information for better understanding the history of basin inversion and its impact on related hydrocarbon-system evolution. | ZHAO Junfeng LIU Chiyang HUANG Lei MOUNTNEY Nigel HAN Shaojia LIU Peng HU Junhao | 2016 | Acta Geologica Sinica(English Edition)2016,90,6: | 2 |
| 15 | In situ atomic-scale observation of dislocation behaviors in twin-structured Pt nanocrystals显示文摘The deformation mechanisms of twin-structured metallic materials have attracted great interest.Though previous theoretical predictions have suggested that the repulsive force of the twin boundary(TB)can significantly affect the deformation of twinstructured metals,it remains unclear whether this prediction applies to experimental conditions.In this paper,the atomic-scaled deformation process of twin-structured Pt nanocrystals was in situ observed using our home-made device in a high-resolution transmission electron microscope.We have shown that the plastic deformation of the twin-structured Pt nanocrystals was governed by full dislocation generation as well as Lomer dislocation(LD)lock formation and destruction.After LD locks were destructed,these full dislocations tended to move towards the surface of the nanocrystals.The findings revealed that due to the ultra-high repulsive force of TB on dislocation,there was no dislocation-TB reaction during the deformation.These findings can enrich our understanding of the dislocation behaviors of twin-structured nanocrystals. | GUO YiZhong SUN Tao FU LiBo HAO LongHu HUANG Ming WEI RuJian LUO JunFeng HE Xin WANG XingQuan XIONG XiaoDong WANG LiHua HAN XiaoDong | 2021 | Science China(Technological Sciences)2021,64,3: | 2 |

| 19 | Weakened interlayer coupling in two-dimensional MoSe2 flakes with screw dislocations显示文摘The screw dislocations are intriguing defects that are often observed in natural and artificial materials. The dislocation spirals break the reflection and inversion symmetries of the lattices and modify the interlayer coupling in layer-structured materials, inducing additional complexity in layer stacking and thus novel properties in materials. Here, we report on the interlayer coupling of two-dimensional (2D) MoSe2 flakes with screw dislocations by atomic force microscopy (AFM), Raman spectra and photoluminescence (PL) spectra. By controlling the supersaturation conditions, 2D MoSe2 flakes with screw dislocations are grown on amorphous SiO2 substrates by chemical vapor deposition (CVD). AFM measurements reveal that the interlayer spacing in such 2D MoSe2 flakes with screw dislocation is slightly widened with respect to the normal AA- or AB-stacked ones due to the presence of the screw dislocations. Raman and PL spectra show that the interlayer coupling is weaker and thus the band gap is wider than that in the normal AA- or AB-stacked ones. Our work demonstrates that the interlayer coupling of 2D transition metal dichalcogenides (TMDCs) flakes can be tuned by the induction of screw dislocations, which is very helpful for developing novel catalysts and electronic devices. | Xiangzhuo Wang Huixia Yang Rong Yang Qinsheng Wang Jingchuan Zheng Lu Qiao Xianglin Peng Yongkai Li Dongyun Chen Xiaolu Xiong Junxi Duan Guangyu Zhang Jie Ma Junfeng Han Wende Xiao Yugui Yao | 2019 | Nano Research2019,12,8: | 1 |
| 20 | A New Species of Septuconularia(Hexangulaconulariidae,Cnidaria)from Cambrian Stage 2,South China显示文摘Hexangulaconulariids,an extinct family of medusozoan small shelly fossils(SSFs),were a conspicuous component of early Cambrian,shallow marine platform communities in South China.Described herein is Septuconularia crassiformis sp.nov.from Bed 5 of the Yanjiahe Formation(Cambrian Stage 2)in the Three Gorges area of Hubei Province.The new species differs from the type and only other known species,S.yanjiaheensis,in the shape of the abapical portion and in the degree of curvature of the adapertural margin.The anatomy of the apical portion of the new species is unknown.The diagnosis of the genus Septuconularia is emended and the spatio-temporal distribution of hexangulaconulariids in South China is summarized.Finally,S.yanjiaheensis,with its slit-like aperture and very narrow transverse cross-section,may have been better adapted to the shallow platform environment than the broader S.crassiformis,which appears to have been less common than the type species. | SONG Zuchen GUO Junfeng HAN Jian Heyo VAN ITEN QIANG Yaqin PENG Jiaxin SUN Jie ZHANG Zhifei | 2022 | Acta Geologica Sinica(English Edition)2022,96,3: | 1 |
