| 1 | Comprehensive analysis of CBM recovery in high rank coal reservoir of Jincheng area显示文摘Coalbed methane (CBM) predicting recovery in high rank coal reservoir varies greatly in Jincheng area and it seriously influences efficient and economic exploitation of CBM resource. In order to predict more accurate CBM recovery, we conducted history matching and productivity prediction of vertical well by using COMET 3 reservoir modeling software, innovatively adopted the gas desorption experiment of bulk coal at fixed test pressure, analyzed the recovery extent method of Daning multiple-hole horizontal well and Panzhuang well group, and calculated recovery by sorption isotherm method of 14 vertical CBM wells at the abandonment pressures 1.0, 0.7, 0.5 and 0.3 MPa, respectively. The results show that the reservoir simulation methods (numerical simulation method and the recovery extent method) is more reliable than the theoretical analysis of coal sample (sorption isotherm method and desorption experiment method). Also, desorption experiment method at fixed pressure is superior to sorption isotherm method. Through the comprehensive analysis and linear correction, CBM recovery ratios in high rank coal reservoir of Jincheng area were found to be 38.64%, 49.30%, 59.30%, and 69.20% at the abandonment pressures 1.0, 0.7, 0.5 and 0.3 MPa, respectively. The research results are of significant importance in the CBM exploration and development in Jincheng area. | Liu Aihua Fu Xuehai Luo Bin Luo Peipei Jiao Chunlin | 2013 | International Journal of Mining Science and Technology2013，23，3： | 6 |
| 2 | Splitting and Merging Based Multi-model Fitting for Point Cloud Segmentation显示文摘This paper deals with the massive point cloud segmentation processing technology on the basis of machine vision, which is the second essential factor for the intelligent data processing of three dimensional conformation in digital photogrammetry. In this paper, multi-model fitting method is used to segment the point cloud according to the spatial distribution and spatial geometric structure of point clouds by fitting the point cloud into different geometric primitives models. Because point cloud usually possesses large amount of 3D points, which are uneven distributed over various complex structures, this paper proposes a point cloud segmentation method based on multi-model fitting. Firstly, the pre-segmentation of point cloud is conducted by using the clustering method based on density distribution. And then the follow fitting and segmentation are carried out by using the multi-model fitting method based on split and merging. For the plane and the arc surface, this paper uses different fitting methods, and finally realizing the indoor dense point cloud segmentation. The experimental results show that this method can achieve the automatic segmentation of the point cloud without setting the number of models in advance. Compared with the existing point cloud segmentation methods, this method has obvious advantages in segmentation effect and time cost, and can achieve higher segmentation accuracy. After processed by method proposed in this paper, the point cloud even with large-scale and complex structures can often be segmented into 3D geometric elements with finer and accurate model parameters, which can give rise to an accurate 3D conformation. | Liangpei ZHANG Yun ZHANG Zhenzhong CHEN Peipei XIAO Bin LUO | 2019 | Journal of Geodesy and Geoinformation Science2019，2，2： | 5 |

| 4 | Inhibiting Hv1 channel in peripheral sensory neurons attenuates chronic inflammatory pain and opioid side effects显示文摘Both opioids and nonsteroidal anti-inflammatory drugs(NSAIDS)produce deleterious side effects and fail to provide sustained relief in patients with chronic inflammatory pain.Peripheral neuroinflammation(PN)is critical for initiation and development of inflammatory pain.A better understanding of molecular mechanisms underlying PN would facilitate the discovery of new analgesic targets and the development of new therapeutics.Emerging evidence suggests that peripheral sensory neurons are not only responders to painful stimuli,but are also actively engaged in inflammation and immunity,whereas the intrinsic regulatory mechanism is poorly understood.Here we report the expression of proton-selective ion channel Hv1 in peripheral sensory neurons in rodents and humans,which was previously shown as selectively expressed in microglia in mammalian central nervous system.Neuronal Hv1 was up-regulated by PN or depolarizing stimulation,which in turn aggravates inflammation and nociception.Inhibiting neuronal Hv1 genetically or by a newly discovered selective inhibitor YHV98-4 reduced intracellular alkalization and ROS production in inflammatory pain,mitigated the imbalance in downstream SHP-1-pAKT signaling,and also diminished pro-inflammatory chemokine release to alleviate nociception and morphine-induced hyperalgesia and tolerance.Thus,our data reveal neuronal Hv1 as a novel target in analgesia strategy and managing opioids-related side effects. | Qiansen Zhang Yimin Ren Yiqing Mo Peipei Guo Ping Liao Yuncheng Luo Jie Mu Zhuo Chen Yang Zhang Ya Li Linghui Yang Daqing Liao Jie Fu Juwen Shen Wei Huang Xuewen Xu Yanyan Guo Lianghe Mei Yunxia Zuo Jin Liu Huaiyu Yang Ruotian Jiang | 2022 | Cell Research2022，32，5： | 3 |
| 5 | Tracking SARS-CoV-2 Omicron diverse spike gene mutations identifies multiple inter-variant recombination events显示文摘The current pandemic of COVID-19 is fueled by more infectious emergent Omicron variants.Ongoing concerns of emergent variants include possible recombinants,as genome recombination is an important evolutionary mechanism for the emergence and re-emergence of human viral pathogens.In this study,we identified diverse recombination events between two Omicron major subvariants(BA.1 and BA.2)and other variants of concern(VOCs)and variants of interest(VOIs),suggesting that co-infection and subsequent genome recombination play important roles in the ongoing evolution of SARS-CoV-2.Through scanning high-quality completed Omicron spike gene sequences. | Junxian Ou Wendong Lan Xiaowei Wu Tie Zhao Biyan Duan Peipei Yang Yi Ren Lulu Quan Wei Zhao Donald Seto James Chodosh Zhen Luo Jianguo Wu Qiwei Zhang | 2022 | Signal Transduction and Targeted Therapy2022，7，5： | 3 |
| 6 | ITO@TiO_(2)nanoarray:An efficient and robust nitrite reduction reaction electrocatalyst toward NH_(3)production under ambient conditions显示文摘Ambient electrochemical nitrite(NO_(2)^(-))reduction is viewed as an effective and sustainable approach for simul-taneously removing NO_(2)^(-)and producing ammonia(NH_(3)).However,the complex multi-electron transfer steps involved in the NO_(2)^(-)reduction reaction(NO_(2)^(-)RR)lead to sluggish kinetics and low product selectivity toward NH_(3),underscoring the need for NH_(3)synthesis electrocatalysts with high activity and durability.Herein,we report amorphous indium-tin oxide sputtered on a TiO_(2)nanobelt array on a Ti plate(ITO@TiO_(2)/TP)as a 3D NH_(3)-producing catalyst for the NO_(2)^(-).In 0.5 M LiClO_(4)with 0.1 M NO_(2)^(-),it shows greatly boosted NO_(2)^(-)RR activity toward NH_(3)production,with excellent selectivity,achieving a large NH_(3)yield of 411.3μmol h^(-1)cm^(-2)and a high Faradaic efficiency of 82.6%.It also shows high durability for continuous electrolysis.A Zn-NO_(2)^(-)battery with ITO@TiO_(2)/TP cathode offers an NH_(3)yield of 23.1μmol h^(-1)cm^(-2)and a peak power density of 1.22 m. | Shaoxiong Li Jie Liang Peipei Wei Qian Liu Lisi Xie Yonglan Luo Xuping Sun | 2022 | eScience2022，2，4： | 3 |
| 7 | 增温和放牧对高寒草甸凋落物分解及其养分释放的影响不依赖于凋落物品质显示文摘在放牧生态系统中,增温、放牧和调落物品质共同决定着凋落物分解和养分释放。然而,在以往的研究中这些因子的效应通常被单独地研究。在本研究中,我们在青藏高原高寒草甸开展了一个昼夜非对称增温和中度放牧两因子的调落物分解试验。从每个处理中收集了调落物样品,这些调落物一部分放在它们的来源处理小区,另一部分放在其他处理小区以此来探究增温、放牧以及调落物品质对调落物分解和养分释放的影响。研究结果表明,增温而不是放牧显著增加了调落物质量的损失、单位面积全碳、全氮以及全磷含量的损失,这主要是因为增温增加了落物生物量和分解速率。然而,尽管同时增温放牧处理也加快了调落物分解速率,但由于降低了调落物生物量,所以增温放牧处理并没有显著影响单位面积的凋落物碳和养分释放量。相比木质素含量和碳氮比而言,季节性土壤平均温度能够更好地预测调落物分解速率。增温和放牧对调落物分解存在交互作用,但它们和调落物品质对调落物的影响均不存在交互作用。单位面积的总氮释放的温度敏感性要高于总磷。因此,我们的结果表明,增温对调落物分解以及养分释放的影响要显著大于调落物品质变化对其分解的影响。在高寒草甸,氮释放的增加可能会间接导致土壤磷有效性的缺乏。 | Bowen Li Wangwang Lv Jianping Sun Lirong Zhang Lili Jiang Yang Zhou Peipei Liu Huan Hong Qi Wang Wang A Suren Zhang Lu Xia Zongsong Wang Tsechoe Dorji Ailing Su Caiyun Luo Zhenhua Zhang Shiping Wang | 2022 | Journal of Plant Ecology2022，15，5： | 1 |
| 8 | Iron sites on defective BiOBr nanosheets:Tailoring the molecular oxygen activation for enhanced photocatalytic organic synthesis显示文摘Sunlight-driven activation of molecular oxygen(O_(2))for organic oxidation reactions offers an appealing strategy to cut down the reliance on fossil fuels in chemical industry,yet it remains a great challenge to simultaneously tailor the charge kinetics and promote reactant chemisorption on semiconductor catalysts for enhanced photocatalytic performance.Herein,we report iron sites immobilized on defective BiOBr nanosheets as an efficient and selective photocatalyst for activation of O_(2) to singlet oxygen(^(1)O_(2)).These Fe^(3+) species anchored by oxygen vacancies can not only facilitate the separation and migration of photogenerated charge carrier,but also serve as active sites for effective adsorption of 02.Moreover,low-temperature phosphorescence spectra combined with X-ray photoelectron spectroscopy(XPS)and electronic paramagnetic resonance(EPR)spectra under illumination reveal that the Fe species can boost the quantum yield of excited triplet state and accelerate the energy transfer from excited triplet state to adsorbed O2 via a chemical loop of Fe^(3+)/Fe^(2+),thereby achieving highly efficient and selective generation of ^(1)O_(2).As a result,the versatile iron sites on defective BiOBr nanosheets contributes to near-unity conversion rate and selectivity in both aerobic oxidative coupling of amines to imines and sulfoxidation of organic sulfides.This work highlights the significant role of metal sites anchored on semiconductors in regulating the charge/energy transfer during the heterogeneous photocatalytic process,and provides a new angle for designing high-performance photocatalysts. | Xinhui Ye Yu Li Peipei Luo Bingcai He Xinxing Cao Tongbu Lu | 2022 | Nano Research2022，15，2： | 1 |
| 9 | Super-assembled highly compressible and flexible cellulose aerogels for methylene blue removal from water显示文摘Physical adsorption is a common method to solve the contamination of methylene blue in dyeing wastewater.As a kind of adsorption material,cellulose aerogels with high porosity and surface areas have great potential application in methylene blue removal.However,the week hydrogen bonding between cellulose nanofibers making the cellulose aerogels with the poor mechanical properties and can be easily destroyed during adsorption.Hence,the preparation of cellulose aerogels with high mechanical strength is still a great challenge.Here,we report a robust super-assembly strategy to fabricate cellulose aerogels by combining cellulose nanofibers with PVA and M-K10.The resulting cellulose aerogels not only has a robust chemically cross-linked network,but also has strong H-bonds,which greatly enhance the mechanical properties.The resulting cellulose aerogels possess a low density of 19.32 mg/cm^(3).Furthermore,the cellulose aerogel shows 93%shape recovery under 60%strain(9.5 k Pa under 60%strain)after 100 cycles,showing excellent mechanical property.The adsorption capacity of cellulose aerogel to methylene blue solution of 20 mg/L is 2.28 mg/g and the adsorption kinetics and adsorption isotherms have also been studied.Pseudo-second-order kinetic model and Freundlich isotherm model are more acceptable for indicating the adsorption process of methylene blue on the cellulose aerogel.Thus,this compressible and durable cellulose aerogel is a very prospective material for dyeing wastewater cleanup. | Mingfu Luo Meng Wang Huaipeng Pang Runhao Zhang Jing Huang Kang Liang Pu Chen Peipei Sun Biao Kong | 2021 | Chinese Chemical Letters2021，32，6： | 1 |
| 10 | 高山嵩草植物群落花期物候对增水的响应比对恒定增温和逐步增温的响应更敏感显示文摘有研究表明长期观测的植物花期物候变化温度敏感性与野外控制恒定增温试验所得出的花期物候温度敏感性结果不一致,这可能是由于两种观测方法具有不同的增温模式引起的。因为长期观测的气候变暖实际上是气温逐渐升高的情景,而野外控制增温试验所增加的温度是突然增加且每年保持不变。不同的增温模式是否会导致不同的结果目前还缺乏野外试验证据。此外,不同增温模式的效应还受到降水变化的调控。因此,我们于2015–2018年在高寒高山嵩草草甸开展了一项恒定增温(和对照相比,每年保持恒定增温1°C)和逐步增温(和对照相比,2015年增温0.25°C,以后逐年在前一年基础上再增温0.25°C,到2018年相比对照增温1°C)以及与增水(100%/50%)耦合的野外控制试验。研究结果发现,增温模式并没有显著改变群落花期物候。然而,增水显著提前了早花植物和中花植物的初花期,提前了早花植物的末花期,推迟了中花植物的末花期。增水处理并没有显著改变早花植物的开花持续期,但却显著延长了中花植物的开花持续期,进而延长了该群落的开花持续期。增温速率和增水处理并没有显著的交互作用。前一年的干旱会显著抑制第二年该植物群落的现存最大开花数。因此,无论增温模式如何,降水的改变对该高山嵩草植物群落花期物候的影响要大于增温对其的影响。 | Bowen Li Jianping Sun Shiping Wang Wangwang Lv Yang Zhou Peipei Liu Qi Wang Wang A Suren Zhang Lu Xia Huan Hong Lili Jiang Caiyun Luo Zhenhua Zhang Shilong Piao Yanfen Wang Tsechoe Dorji | 2023 | Journal of Plant Ecology2023，16，2： | 0 |

| 15 | Thermo-mechanical properties of RTM-made carbon fibre/polyimide composite attaching collar under transient heating显示文摘This study focuses on the thermo-mechanical properties of Carbon Fibre/Polyimide Composite(CFPC)attaching collars under transient heating.The CFPC attaching collars were fabricated by a high-temperature resin transfer moulding process,and their thermo-mechanical properties under the conditions of simultaneous transient heating and bending load were investigated.The results show that the attaching collar tends to fail at 118% of the limit load.The failure mode includes the fracture of the connecting screws,local extrusion damage of the hole edges,and slight ablation damage at the outer plies.And there is no observable residual deformation in the composite attaching collar.Furthermore,considering that the material properties vary with temperature,a progressive damage model based on the sequential thermo-mechanical coupling method was established to study the failure mechanism of the attaching collar.Finally,the damage factor of the CFPC was calculated to assess the safety status of the attaching collar.The results show that the primary damage modes of the composite attaching collar are intralaminar failure,which mainly occurs at the heat insulation layer and the hole edges,and these slightly affect the structural bearing capacity.A good correlation between the experiment and FEA is obtained.The test methods and analysis models proposed contribute to the safety assessment of composite structures under transient heating. | Shengda JIANG Chuyang LUO Peng ZHANG Jianwen BAO Peipei CAI Xufeng XIA | 2023 | Chinese Journal of Aeronautics2023，36，3： | 0 |

| 20 | p-Arsanilic acid decontamination over a wide pH range using biochar-supported manganese ferrite material as an effective persulfate catalyst:Performances and mechanisms显示文摘Direct chemical oxidation and pure adsorption could not effectively remove p-Arsanilic acid(p-ASA)and the released inor-ganic arsenic.Herein,one novel biochar supported MnFe_(2)O_(4)(MFB)was synthesized and adopted for p-ASA degradation and synchronous adsorption of the generated inorganic arsenic.The MFB/persulfate(PS)system could remain effective under a wide pH range(3.0-9.0),and the released arsenic could be removed simultaneously by MFB.Mechanism investiga-tion revealed that the functional groups of MFB(i.e.O-C=O and C=O),Fe and Mn oxides on MFB all contributed to PS activation.O_(2)^(·−)and^(1)O_(2)were the main reactive oxygen species(ROS)responsible for p-ASA degradation,and^(1)O_(2)was the predominant ROS.Besides,the MFB possessed superior reusability.Therefore,it is expected to develop a potential method for organic arsenic contaminants removal via an oxidation-adsorption process,and the results could also shed light on the better understanding of the PS activation mechanisms. | Bin Yao Xia Chen Kun Zhou Zirui Luo Peipei Li Zihui Yang Yaoyu Zhou | 2022 | Biochar2022，4，1： | 0 |
