| 1 | Simultaneous heterotrophic nitrification and aerobic denitrification at high initial phenol concentration by isolated bacterium Diaphorobacter sp. PD-7显示文摘A strain capable of phenol degradation, heterotrophic nitrification and aerobic denitrification was isolated from activated sludge of coking-plant wastewater ponds under aerobic condition. Based on its morphology, physiology,biochemical analysis and phylogenetic characteristics, the isolate was identified as Diaphorobacter sp. PD-7.Biodegradation tests of phenol showed that the maximum phenol degradation occurred at the late phase of exponential growth stages, with 1400 mg·L-1phenol completely degraded within 85 h. Diaphorobacter sp. PD-7accumulated a vast quantity of phenol hydroxylase in this physiological phase, ensuring that the cells quickly utilize phenol as a sole carbon and energy source. The kinetic behavior of Diaphorobacter sp. PD-7 in batch cultures was investigated over a wide range of initial phenol concentrations(0–1400 mg·L-1) by using the Haldane model,which adequately describes the dynamic behavior of phenol biodegradation by strain Diaphorobacter sp. PD-7. At initial phenol concentration of 1400 mg·L-1, batch experiments(0.25 L flask) of nitrogen removal under aerobic condition gave almost entirely removal of 120.69 mg·L-1ammonium nitrogen within 75 h, while nitrate nitrogen removal reached 91% within 65 h. Moreover, hydroxylamine oxidase, periplasmic nitrate reductase and nitrite reductase were successfully expressed in the isolate. | Qilong Ge Xiuping Yue Guoying Wang | 2015 | Chinese Journal of Chemical Engineering2015，23，5： | 26 |
| 2 | The cGAS-STING signaling in cardiovascular and metabolic diseases: Future novel target option for pharmacotherapy显示文摘The cyclic GMP-AMP synthase(cGAS)-stimulator of interferon genes(STING) signaling exert essential regulatory function in microbial-and onco-immunology through the induction of cytokines, primarily type I interferons. Recently, the aberrant and deranged signaling of the cGAS-STING axis is closely implicated in multiple sterile inflammatory diseases, including heart failure,myocardial infarction, cardiac hypertrophy, nonalcoholic fatty liver diseases, aortic aneurysm and dissection, obesity, etc. This is because of the massive loads of damage-associated molecular patterns(mitochondrial DNA, DNA in extracellular vesicles) liberated from recurrent injury to metabolic cellular organelles and tissues, which are sensed by the pathway. Also, the cGAS-STING pathway crosstalk with essential intracellular homeostasis processes like apoptosis, autophagy, and regulate cellular metabolism.Targeting derailed STING signaling has become necessary for chronic inflammatory diseases. Meanwhile, excessive type I interferons signaling impact on cardiovascular and metabolic health remain entirely elusive. In this review, we summarize the intimate connection between the cGAS-STING pathway and cardiovascular and metabolic disorders. We also discuss some potential small molecule inhibitors for the pathway. This review provides insight to stimulate interest in and support future research into understanding this signaling axis in cardiovascular and metabolic tissues and diseases. | Patrick Kwabena Oduro Xianxian Zheng Jinna Wei Yanze Yang Yuefei Wang Han Zhang Erwei Liu Xiumei Gao Mei Du Qilong Wang | 2022 | Acta Pharmaceutica Sinica B2022，12，1： | 18 |
| 3 | A hybridized weak Galerkin finite element scheme for the Stokes equations显示文摘In this paper a hybridized weak Galerkin(HWG) finite element method for solving the Stokes equations in the primary velocity-pressure formulation is introduced.The WG method uses weak functions and their weak derivatives which are defined as distributions.Weak functions and weak derivatives can be approximated by piecewise polynomials with various degrees.Different combination of polynomial spaces leads to different WG finite element methods,which makes WG methods highly flexible and efficient in practical computation.A Lagrange multiplier is introduced to provide a numerical approximation for certain derivatives of the exact solution.With this new feature,the HWG method can be used to deal with jumps of the functions and their flux easily.Optimal order error estimates are established for the corresponding HWG finite element approximations for both primal variables and the Lagrange multiplier.A Schur complement formulation of the HWG method is derived for implementation purpose.The validity of the theoretical results is demonstrated in numerical tests. | ZHAI QiLong ZHANG Ran WANG XiaoShen | 2015 | Science China Mathematics2015，58，11： | 10 |
| 4 | Prediction of the trajectory of the manned spacecraft SHENZHOU-7 deploying a parachute based on a fine wind field显示文摘Given that horizontal wind plays an important role in predicting the trajectory of the manned spacecraft SHENZHOU-7 when employing a parachute, the China Meteorological Administration conducted an experiment involving high-resolution wind ob servation, analysis and prediction between September 21 and 28, 2008. In this work, an algorithm for tracking a spacecraft de ploying a parachute is studied. High-resolution wind profiles obtained from a numerical weather model, upper-atmosphere soundings and mobile incoherent Doppler wind lidar are compared. Forward and backward trajectory predictions based on various wind profiles, as well as their differences, are presented. In addition, the trajectory of SHENZHOU-7 is predicted using different wind profiles, and the predicted parachute-opening and landing points are compared with the observed points. Results indicate that a high-resolution numerical weather model and fine observation data can offer more-detailed wind information for the prediction of spacecraft trajectories and can thus help in the editing and sending of flight commands, consequently increas ing the accuracy and reliability of landing on an assigned spot and reducing the search area and rescue time. | GUO ZhiMei MIAO QiLong WANG ShuDong LI Huang | 2011 | Science China Earth Sciences2011，54，9： | 5 |

| 7 | Porous-hollow nanorods constructed from alternate intercalation of carbon and MoS2 monolayers for lithium and sodium storage显示文摘Weak ion diffusion and electron transport due to limited interlayer spacing and poor electrical conductivity have been identified as critical roadbacks for fast and abundant energy storage of both MoS2-based lithium ion batteries (LIBs) and sodium ion batteries (SIBs). In this work, MoS2 porous-hollow nanorods (MoS2/m-C800) have been designed and synthesized via an annealing-followed chemistry-intercalated strategy to solve the two issues. They are uniformly assembled from ultrathin MoS2 nanosheets, deviated to the rod-axis direction, with expanded interlayer spacing due to alternate intercalation of N-doped carbon monolayers between the adjacent MoS2 monolayers. Electrochemical studies of the MoS2/m-C800 sample, as an anode of LIBs, demonstrate that the superstructure can deliver a reversible discharge capacity of 1,170 mAh·g^-1 after 100 cycles at 0.2 A·g^-1 and maintain a reversible capacity of 951 mAh·g^-1 at 1.25 A·g^-1 after 350 cycles. While for SIBs, the superstructure also delivers a reversible discharge capacity of 350 mAh·g^-1 at 0.5 A-g-1 after 500 cycles and exhibits superior rate capacity of 238 mAh·g^-1 at 15 A·g^-1 .The excellent electrochemical performance is closely related with the hierarchical superstructures, including expanded interlayer spacing, alternate intercalation of carbon monolayers and mesoporous feature, which effectively reduce ion diffusion barrier, shorten ion diffusion paths and improve electrical conductivity. | Laiying Jing Gang Lian Junru Wang Mingwen Zhao Xizheng Liu Qilong Wang Deliang Cui Ching-Ping Wong | 2019 | Nano Research2019，12，8： | 3 |
| 8 | Key CO_(2)capture technology of pure oxygen exhaust gas combustion for syngas-fueled high-temperature fuel cells显示文摘Integrated gasification fuel cells(IGFCs)integrating high-temperature solid oxide fuel cell technology with CO_(2)capture processes represents highly-efficient power systems with negligible CO_(2)emissions.Flame burning with pure oxygen is an ideal method for fuel cell exhaust gas treatment,and this report describes experimental and numerical studies regarding an oxy-combustor for treating the exhaust gas of a 10 kW IGFC system anode.The applied simulation method was verified based on experiments,and the key performance indices of the combustor were studied under various conditions.It was determined that 315 K was the ideal condensation temperature to obtain flame stability.Under these pure oxygen flame burning conditions,CO was almost completely converted,and the dry mole fraction of CO_(2)after burning was C 0.958 when there was up to 5%excess O_(2).Overall,5%excess O_(2)was recommended to maximize CO_(2)capture and promote other environmental considerations.Additionally,the optimal tangential fuel jet angle to control the liner temperature was approximately 25°.The total fuel utilization had to be high enough to maintain the oxygen flame temperature of the anode exhaust gas below 1800 K to ensure that the system was environmentally friendly.The results presented herein have great value for designing IGFCs coupled with CO_(2)capture systems. | Hanlin Wang Qilong Lei Pingping Li Changlei Liu Yunpeng Xue Xuewei Zhang Chufu Li Zhibin Yang | 2021 | International Journal of Coal Science & Technology2021，8，3： | 3 |
| 9 | Surface-modified Zn_(0.5)Ti_(0.5)NbO_(4) particles filled polytetrafluoroethylene composite with extremely low dielectric loss and stable temperature dependence显示文摘Polymer-ceramic composites are widely applied in microwave substrate materials due to the excellent dielectric properties and simple preparation process recently.Polytetrafluoroethylene-based(PTFE)composites filled with Zn_(0.5)Ti_(0.5)NbO_(4)(ZTN)ceramic particles were fabricated by hot-pressing.The particles were modified by C_(14)H_(19)F_(13)O_(3)Si to enhance the interface compatibility between PTFE and ZTN powders,which was characterized by X-ray photoelectron spectroscopy(XPS)and contact angle.The surface characteristic of particles transformed into hydrophobicity and tight microstructure as well as better dielectric properties were obtained after the surface modification.The microstructure,dielectric,thermal,mechanical properties,and water absorption of the composites concerning ZTN content were investigated.Modified ZTN/PTFE composites with 50 vol% ZTN particles exhibit excellent dielectric properties with a high dielectric constant of 8.3,an extremely low dielectric loss of 0.00055 at 7 GHz,and a stable temperature coefficient of the dielectric constant of-12.2 ppm/℃.All the properties show modified ZTN particles filled PTFE composite is the potential material for microwave substrate application. | Hao WANG Fuming ZHOU Jianming GUO Yuanyuan ZHANG Hui YANG Qilong ZHANG | 2020 | Journal of Advanced Ceramics2020，9，6： | 3 |
| 10 | A stage-specific cell-manipulation platform for inducing endothelialization on demand显示文摘Endothelialization is of great significance for vascular remodeling,as well as for the success of implanted vascular grafts/stents in cardiovascular disease treatment.However,desirable endothelialization on synthetic biomaterials remains greatly challenging owing to extreme difficulty in offering dynamic guidance on endothelial cell(EC)functions resembling the native extracellular matrix-mediated effects.Here,we demonstrate a bilayer platform with near-infrared-triggered transformable topographies,which can alter the geometries and functions of human ECs by tunable topographical cues in a remote-controlled manner,yet cause no damage to the cell viability.The migration and the adhesion/spreading of human ECs are respectively promoted by the temporary anisotropic and permanent isotropic topographies of the platform in turn,which appropriately meet the requirements of stage-specific EC manipulation for endothelialization.In addition to the potential of promoting the development of a new generation of vascular grafts/stents enabling rapid endothelialization,this stage-specific cell-manipulation platform also holds promise in various biomedical fields,since the needs for stepwise control over different cell functions are common in wound healing and various tissue-regeneration processes. | Qilong Zhao Juan Wang Yunlong Wang Huanqing Cui Xuemin Du | 2020 | National Science Review2020，7，3： | 3 |
| 11 | A comparative study of Mg-Gd-Y-Zr alloy cast by metal mould and sand mould显示文摘The differences of the microstructure and mechanical property between metal mould and sand mould cast Mg-10Gd-3Y-Zr alloy were investigated both under as-cast condition and after solution heat treatment.In the as-cast specimens,the microstructure is similar and composed of α-Mg solid solution and eutectic compound of α-Mg+ Mg24(Gd,Y) 5;whereas the grain size using metal mould and sand mould is 27 μm and 71 μm,respectively.The eutectic compound of metal mould cast alloy was completely dissolved after solution treated at 500℃ for 8 h,however it needs higher temperature(525 ℃) and longer time(12 h) to achieve the absolute dissolving under sand mould condition.In contrast to metal mould,the peak time of sand mould alloy aged at 225 ℃ and 250 ℃ of was advanced by 4 h and 6 h,respectively.The precipitation reaction sequence in sand mould cast Mg-10Gd-3Y-Zr alloy during isothermal ageing at 250 ℃ follows S.S.S.S.→β″(D019) →β'(cboc) →β1(fcc) →β(fcc) ,which is similar to that in the alloy cast using metal mould. | Wang Qilong Wu Guohua Hou Zhengquan Chen Bin Zheng Yun Ding Wenjiang | 2010 | China Foundry2010，7，1： | 3 |

| 13 | Negative thermal expansion: Mechanisms and materials显示文摘Negative thermal expansion(NTE)of materials is an intriguing phenomenon challenging the concept of traditional lattice dynamics and of importance for a variety of applications.Progresses in this field develop markedly and update continuously our knowledge on the NTE behavior of materials.In this article,we review the most recent understandings on the underlying mechanisms(anharmonic phonon vibration,magnetovolume effect,ferroelectrorestriction and charge transfer)of thermal shrinkage and the development of NTE materials under each mechanism from both the theoretical and experimental aspects.Besides the low frequency optical phonons which are usually accepted as the origins of NTE in framework structures,NTE driven by acoustic phonons and the interplay between anisotropic elasticity and phonons are stressed.Based on the data documented,some problems affecting applications of NTE materials are discussed and strategies for discovering and design novel framework structured NET materials are also presented. | Erjun Liang Qiang Sun Huanli Yuan Jiaqi Wang Gaojie Zeng Qilong Gao | 2021 | Frontiers of physics2021，16，5： | 3 |
| 14 | In situ FTIR investigation on phase transformations in BN nanoparticles显示文摘Fourier transformation infrared spectrum (FTIR) was employed to investigate phase transformation of nanoparticle BN, containing eBN, rBN, wBN and cBN, in which eBN and rBN are the main components. We found that part of eBN was converted into rBN at 200―350℃. At and above 400℃, eBN transformed into wBN, and some of wBN were converted into cBN simultaneously. This conclusion is supported by the results from high- resolution transmission electron microscopic (HRTEM) and Raman spectroscopic measurements. In this work, the converting processes be- tween different BN phases were continuously monitored by in situ FTIR spectroscopy. The results will be helpful for synthesis of cBN at moderate conditions. | YU Lili GAO Bin CHEN Zhi SUN Chuantao CUI Deliang WANG Chengjian WANG Qilong JIANG Minhua | 2005 | Chinese Science Bulletin2005，50，24： | 2 |
| 15 | Response of Internal Waves to 2005 Typhoon Damrey over the Northwestern Shelf of the South China Sea显示文摘Continuous observation of sea water temperature and current was made at Wenchang Station(19°35′N,112°E) in 2005. The data collected indicate vigorous internal waves of both short periods and tidal and near-inertial periods. The temperature and current time series during 18-30 September were examined to describe the upper ocean internal wave field response to Typhoon Damrey(0518) . The strong wind associated with the typhoon,which passed over the sea area about 45 km south of Wenchang Station on 25 September,deepened the mixed layer depth remarkably. It decreased the mixed layer temperature while increasing the deep layer temperature,and intensified the near-inertial and high-frequency fluctuations of temperature and current. Power spectra of temperature and current time series indicate significant deviations from those obtained by using the deep ocean internal wave models characterized by a power law. The frequency spectra were dominated by three energetic bands:around the inertial frequency(7.75× 10-6 Hz) ,tidal frequencies(1.0×10-5 to 2.4×10-5 Hz) ,and between 1.4×10-4 and 8.3×10-4 Hz. Dividing the field data into three phases(before,during and after the typhoon) ,we found that the typhoon enhanced the kinetic energy in nearly all the frequency bands,especially in the surface water. The passage of Damrey made a major contribution to the horizontal kinetic energy of the total surface current variances. The vertical energy density distribution,with its peak value at the surface,was an indication that the energy injected by the strong wind into the surface current could penetrate downward to the thermocline. | WANG Gang QIAO Fangli HOU Yijun DAI Dejun LIN Min ZHANG Qilong WANG Gang YIN Baoshu | 2008 | Journal of Ocean University of China2008，7，3： | 2 |

| 17 | Biomass-derived hard carbon microtubes with tunable apertures for high-performance sodium-ion batteries显示文摘Sodium-ion batteries(SIBs)are considered the most up-and-coming complements for large-scale energy storage devices due to the abundance and cheap sodium.However,due to the bigger radius,it is still a great challenge to develop anode materials with suitable space for the intercalation of sodium ions.Herein,we present hard carbon microtubes(HCTs)with tunable apertures derived from low-cost natural kapok fibers via a carbonization process for SIBs.The resulted HCTs feature with smaller surface area and shorter Na+diffusion path benefitting from their unique micro-nano structure.Most importantly,the wall thickness of HCTs could be regulated and controlled by the carbonization temperature.At a high temperature of 1,600℃,the carbonized HCTs possess the smallest wall thickness,which reduces the diffusion barrier of Na+and enhances the reversibility Na+storage.As a result,the 1600HCTs deliver a high initial Coulombic efficiency of 90%,good cycling stability(89.4%of capacity retention over 100 cycles at 100 mA·g^(−1)),and excellent rate capacity.This work not only charts a new path for preparing hard carbon materials with adequate ion channels and novel tubular micro-nano structures but also unravels the mechanism of hard carbon materials for sodium storage. | Pin Song Shiqiang Wei Jun Di Jun Du Wenjie Xu Daobin Liu Changda Wang Sicong Qiao Yuyang Cao Qilong Cui Pengjun Zhang Liaobo Ma Jiewu Cui Yan Wang Yujie Xiong | 2023 | Nano Research2023，16，4： | 1 |

| 19 | Synergistic effects of phosphoric acid modified hydrochar and coal gangue-based zeolite on bioavailability and accumulation of cadmium and lead in contaminated soil显示文摘In this paper,a novel compound was developed by mixing H_(3)PO_(4)-modified cauliflower leaves hydrochar(CLH)and coal gangue-based Na-X zeolite(ZL).An alkaline soil contaminated with cadmium(Cd)and lead(Pb)was amended through the individual and synergistic application of CLH and ZL(1%CLH,2%CLH,1%ZL,2%ZL and 1%CLH+1%ZL),and Chinese cabbage was grown on it.Individual application of CLH was superior to ZL on decreasing the pH of alkaline soil and increasing soil available phosphorus(Olsen-P)and soil organic matter(SOM).In contrast,their combined application significantly improved the soil cation exchange capacity(CEC).Besides,the 1%CLH+1%ZL was the most efficient treatment in decreasing diethylenetriamine pentaacetate(DTPA)-extractable Cd/Pb and concentrations of these two metals in cabbage root and shoot.Their synergistic application could better increase Cd and Pb immobilization and cabbage yield than their alone application.Furthermore,the immobilization of Pb for all treatments was higher than that of Cd.The synergistic immobilization mechanism of CLH and ZL reflected that the CLH precipitated and complexed with these two metals,which may block the pores of hydrochar or wrap on the surface of hydrochar.So the continuous adsorption and complexation were prevented.Nevertheless,ZL could probably alleviate this obstacle.This finding provides helpful information about using CLH combined with ZL as a soil stabilizer to immobilize heavy metals in contaminated alkaline soil. | Qilong Ge Qi Tian Sufang Wang Fang Zhu | 2022 | Chinese Journal of Chemical Engineering2022，35，6： | 1 |
