| 2 | Composition, source, mass closure of PM_(2.5) aerosols for four forests in eastern China显示文摘PM2.5 aerosols were collected in forests along north latitude in boreal-temperate, temperate, subtropical and tropical climatic zones in eastern China, i.e., Changbai Mountain Nature Reserve (CB), Dongping National Forest Park in Chongming Island (CM), Dinghu Mountain Nature Reserve (DH), Jianfengling Nature Reserve in Hainan Island (HN). The mass concentrations of PM2.5, organic carbon (OC), elemental carbon (EC), water soluble organic carbon (WSOC) as well as concentrations of ten inorganic ions (F-, Cl-, NO3-, SO42-, C2O42-, NH4+, Na+, K+, Ca2+, Mg2+) were determined. Aerosol chemical mass closures were achieved. The 24-hr average concentrations of PM2.5 were 38.8, 89.2, 30.4, 18 μg/m3 at CB, CM, DH and HN, respectively. Organic matter and EC accounted for 21%-33% and 1.3%-2.3% of PM2.5 mass, respectively. The sum of three dominant secondary ions (SO42-, NO3-, NH4+) accounted for 44%, 50%, 45% and 16% of local PM2.5 mass at CB, CM, DH and HN, respectively. WSOC comprised 35%-65% of OC. The sources of PM2.5 include especially important regional anthropogenic pollutions at Chinese forest areas. | Li Li Wu Wang Jialiang Feng Dongping Zhang Huaijian Li Zeping Gu Bangjin Wang Guoying Sheng Jiamo Fu | 2010 | Journal of Environmental Sciences2010，22，3： | 45 |
| 3 | Polychlorinated biphenyls in the atmosphere of Taizhou,a major e-waste dismantling area in China显示文摘PM2.5,total suspended particles(TSP) and gas phase samples were collected at two sites of Taizhou,a major e-waste dismantling area in China.Concentrations,seasonal variations,congener profiles,gas-particle partitioning and size distribution of the atmospheric polychlorinated biphenyls(PCBs) were studied to assess the current state of atmospheric PCBs after the phase out of massive historical dismantling of PCBs containing e-wastes.The average 38PCBs concentration in the ambient air(TSP plus gas phase) near the e-waste dismantling area was(12,407 ± 9592) pg/m3 in winter,which was substantially lower than that found one decade ago.However,the atmospheric PCBs level near the e-waste dismantling area was 54 times of the reference urban site,indicating that the impact of the historical dismantling of PCBs containing e-wastes was still significant.Tri-Penta-CBs were dominant homologues,consisting with their dominant global production.Size distribution of particle-bound PCBs showed that higher chlorinated CBs tended to partition more to the fine particles,facilitating its long range air transportation. | Wenliang Han Jialiang Feng Zeping Gu Minghong Wu Guoying Sheng Jiamo Fu | 2010 | Journal of Environmental Sciences2010，22，4： | 18 |
| 4 | Sedimentary architecture models of deepwater turbidite channel systems in the Niger Delta continental slope,West Africa显示文摘This paper studied an architecture model of turbidite channel systems based on the shallow- layer high resolution 3D seismic information in the deepwater area in the Niger Delta continental slope, West Africa as a prototype model. Different types of channel systems were identified and the corresponding architecture models were established. The controlling factors, evaluation criteria and spatial distribution of different channel systems were analyzed. This study shows that turbidite channel systems of West Africa could be classified into three types; confined, semi-confined and unconfined, according to the condition of canyon and the levees on both sides. On one hand, along the transport direction, channel system evolves from confined to unconfined. Within channel systems, channel complexes, including two types of incised and enveloped, are the most important reservoir bodies. On the other hand, there is a channel complex evolution from incised to enveloped vertically. The geological factors exert impacts of different levels on the architecture of the turbidite channels in different sedimentary systems or even within the same system. | Liu Li Zhang Tingshan Zhao Xiaoming Wu Shenghe Hu Jialiang Wang Xing Zhang Yikai | 2013 | Petroleum Science2013，10，2： | 16 |
| 5 | Diurnal variations of polycyclic aromatic hydrocarbons associated with PM_(2.5) in Shanghai, China显示文摘Forty-eight daily time interval PM2.5 samples were collected from December 2006 to January 2008 in an urban site in Shanghai, China. Concentrations and compositions of polycyclic aromatic hydrocarbons (PAHs) were analyzed with GC-MS to study the diurnal and seasonal variations and to identify the main emitting sources. The diurnal variation of the PAHs concentrations was greater in the late autumn and winter sampling days, and was greatly influenced by meteorological conditions such as wind speed and ambient temperature. The concentration of PAHs in the mornings (6:30-10:00) increased distinctly, and was high in the late autumn and winter sampling days, indicating the contribution from vehicle emissions during rush hours. The diurnal variation of the high molecular weight PAHs did not seem to be controlled by the shift of gas-particle partitioning due to temperature variation, instead, it could be indicative of the variation in the source. Statistical analyses showed that the concentrations of PAHs were negatively correlated with temperature and wind speed, and positively correlated with relative humidity. Diagnostic ratios of PAHs suggested mixed emission sources of petroleum and coal/biomass combustion for PAHs in the PM2.5 in Shanghai. | Zeping Gu Jialiang Feng Wenliang Han Li Li Minghong Wu Jiamo Fu Guoying Sheng | 2010 | Journal of Environmental Sciences2010，22，3： | 13 |
| 6 | Synergistically Directed Assembly of Aromatic Stacks Based Metal-Organic Frameworks by Donor-Acceptor and Coordination Interactions显示文摘A synergistically directed assembly approach to distinctive metal-organic frameworks utilizing both donor-acceptor (D-A) interaction from aromatic systems and coordination interactions is presented.Based on such an approach,the coronene-tpt (tpt =2,4,6-tri(4-pyridyl)-1,3,5-triazine) stacks based coronene-MOF-1-4 have been successfully fabricated.Their structural discrepancies with coroneneabsent control products,1'-4',illustrate clearly the significance of coronene-tpt based D-A interactions in these architectures.All these coronene-MOFs contain varied coronene-tpt stacks as organic secondary building blocks (SBUs),which are closely interrelated with the coordination based framework structures.Moreover,porous coronene-MOF-1 and-2 exhibit high physicochemical stability and significant light hydrocarbons storage and separation performances. | Xi Wang Ying Zhang Ze Chang Hui Huang Xiao-Ting Liu Jialiang Xu Xian-He Bu | 2019 | Chinese Journal of Chemistry2019，37，9： | 11 |
| 7 | Solvent extraction of vanadium from sulfuric acid solution显示文摘The behaviour of vanadium(V) extracted from sulfuric acid solution was investigated using Cyanex 923 as an extractant. The effects of the concentration of Cyanex 923 and the pH of the solution were studied. The extraction of vanadium(V) increases with the increase of Cyanex 923 concentration and shaking time. Cyanex 923 can extract vanadium(V) from sulfuric acid solution at low pH conditions, and the best pH conditions for extraction of vanadium(V) are at pH 1.0-2.0. The species extracted into the organic phase is VO2HSO4 with one molecule of Cyanex 923. Equilibrium studies were used to assess the extraction efficiency of vanadium(V) recovery from the sulfuric acid solution. | WANG Mingyu ZHANG Guiqing WANG Xuewen ZHANG Jialiang | 2009 | Rare Metals2009，28，3： | 11 |
| 8 | Compound-specific carbon isotope compositions of individual long-chain n-alkanes in severe Asian dust episodes in the North China coast in 2002显示文摘The molecular compositions and com- pound-specific carbon isotope compositions of indi- vidual long-chain n-alkanes of atmospheric aerosols collected during two severe Asian dust episodes in Qingdao in spring of 2002 were analyzed using gas chromatography/mass spectrometry (GC/MS) and gas chromatography/isotope ratio mass spectrometry (GC/IRMS). Typical plant wax n-alkanes (C29 and C31) had lower δ 13C values than those from anthropo- genic (engine exhaust) sources (C21―C23). The av- erage δ 13C value of plant wax n-alkane C29 in non-dust episode periods was -30.5‰ (?30.3‰― ?31.9‰), while -31.3‰ (?31.1‰―?31.5‰) in dust episode periods; for C31, it was ?31.4‰ (?31.1‰― ?33.0‰) in non-dust episode periods, and ?31.7‰ (?31.3‰―?32.6‰) in dust episode periods. Plant wax in the dust episode samples was mainly from herbaceous plants via long-range transport, while local plant wax was mainly from deciduous plants and woody plants. In North China coast, 83.3% of the plant wax in the severe dust episode samples was from C3 plants while 80.0% for the non-dust samples, indicating that plant wax transported to the north- western Pacific Ocean by airborne dust from East Asia was mainly from C3 plants. The results suggestthat the molecular and molecular-isotopic composi- tions of individual long-chain n-alkanes can, as an effective indicator, identify the terrestrial organic components in the dust from East Asia and sedi- ments in the northwest Pacific Ocean. | GUO Zhigang LI Juyuan FENG Jialiang FANG Ming YANG Zuosheng | 2006 | Chinese Science Bulletin2006，51，17： | 8 |
| 9 | Shape anisotropic Fe3O4 nanotubes for efficient microwave absorption显示文摘Although Fe3O4 particles have exhibited excellent microwave absorbing capacity and widely used in practical application due to the synergistic effect of magnetic loss and dielectric loss,their applications are still limited for the required high mass fraction in absorbers.To overcome this problem,the development of Fe3O4 materials with low dimensional structures is necessary.In this study,the shape anisotropic Fe3O4 nanotubes(NTs)with low mass ratios were applied to realize efficient microwave absorption.The NTs with different aspect ratios were prepared through facile electrospinning followed by two-step thermal treatments and mechanical shearing.The cross-linked nanotubular structure enabled the absorbers to have much higher electrical conductivity,multiple scattering,polarization relaxation and better anti-reflection surface,while the shape anisotropic NTs maintained significant multiple resonances with stronger coercivity.These all were beneficial to microwave absorption with enhanced dielectric loss,magnetic loss and sterling impedance matching.Results showed that the absorber with 33.3 wt.%of short Fe3O4 NTs had minimum reflection loss of-58.36 dB at 17.32 GHz with a thickness of 1.27 mm,and had the maximum effective absorbing bandwidth(EAB)of 5.27 GHz when the thickness was 1.53 mm.The absorber with 14.3 wt.%of long Fe3O4 NTs presented the widest EAB in certain radar band with attenuated 80.75%X band and 85%Ku band energy bellow-10 dB at the thickness of 2.65 and 1.53 mm,respectively.This study provided an approach for the development of shape anisotropic magnetic absorbing materials,and broadened their practical applications as magnetic absorbers. | Jialiang Pan Honggui Guo Min Wang Hui Yang Haowen Hu Peng Liu Hongwei Zhu | 2020 | Nano Research2020，13，3： | 8 |
| 10 | Actively priming autophagic cell death with novel transferrin receptor-targeted nanomedicine for synergistic chemotherapy against breast cancer显示文摘Recently, considerable attention in the field of cancer therapy has been focused on the mammalian rapamycin target(m TOR), inhibition of which could result in autophagic cell death(ACD). Though novel combination chemotherapy of autophagy inducers with chemotherapeutic agents is extensively investigated, nanomedicine-based combination therapy for ACD remains in infancy. In attempt to actively trigger ACD for synergistic chemotherapy, here we incorporated autophagy inducer rapamycin(RAP) into 7 pep-modified PEG-DSPE polymer micelles(7 pep-M-RAP) to specifically target and efficiently priming ACD of MCF-7 human breast cancer cells with high expression of transferrin receptor(Tf R). Cytotoxic paclitaxel(PTX)-loaded micelle(7 pep-M-PTX) was regarded as chemotherapeutic drug model. We discovered that with superior intracellular uptake in vitro and more tumor accumulation of micelles in vivo, 7 pep-M-RAP exhibited excellent autophagy induction and synergistic antitumor efficacy with 7 pep-M-PTX. Mechanism study further revealed that 7 pep-M-RAP and 7 pep-MPTX used in combination provided enhanced efficacy through induction of both apoptosis-and mitochondria-associated autophagic cell death. Together, our findings suggested that the targeted excess autophagy may provide a rational strategy to improve therapeutic outcome of breast cancer, and simultaneous induction of ACD and apoptosis may be a promising anticancer modality. | Dong Mei Binlong Chen Bing He Haibin Liu Zhiqiang Lin Jialiang Lin Xiaoyan Zhang Ning Sun Libo Zhao Xiaoling Wang Qiang Zhang | 2019 | Acta Pharmaceutica Sinica B2019，9，5： | 8 |

| 13 | Enhanced flame-retardant performance of poly(lactic acid)(PLA) composite by using intrinsically phosphorus-containing PLA显示文摘The intrinsically phosphorous-containing flame-retardant poly(lactic acid)(P-PLA) was synthesized through the chain extension of L-lactide and 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide(DOPO) derivative, then P-PLA was melt blended with neat PLA to produce flame-retardant PLA composite(FR-PLA). The flame-retardant properties of FR-PLAs were investigated by Limiting Oxygen Index(LOI), UL-94, and Cone Calorimeter Tests, the results indicated that the flame-retardant properties of PLA composites were significantly improved with the addition of P-PLA due to its excellent ability to carbonize and dilute combustible gases. The LOI value of FRPLA10 composite(consisting of 90 wt% neat PLA and 10 wt% P-PLA) increased from 20.5 to 27.8 and UL-94 rating reached up to V-1, the peak heat release rate and total heat release of FR-PLA composite were lower than those of neat PLA. The flame-retardant mechanism of FR-PLA depended on both condensed and gaseous phases,which was confirmed by the FTIR, Raman and TG-FTIR. Besides, the tensile strength of FR-PLA10 slightly decreased from 72.4 to 61.8 MPa, which met the requirements of most practical applications. Therefore, the modification method used in this work presented a feasible approach to prepare FR-PLA composite with satisfactory mechanical property. | Senlong Yu Hengxue Xiang Jialiang Zhou Meifang Zhu | 2018 | Progress in Natural Science:Materials International2018，28，5： | 8 |
| 14 | Intriguing anti-superbug Cu2O@ZrP hybrid nanosheet with enhanced antibacterial performance and weak cytotoxicity显示文摘In view of it's strong antibacterial function and minor toxicity,cuprous oxide (Cu2O) is frequently used in various broad-spectrum antibacterial reagents.Nonetheless the undesirable effects of superbugs still remain challenging.In this research,a chemical deposition approach is used to prepare a Cu2O@ZrP composite with nanosheet configuration demonstrating excellent dispersibility and antibacterial traits.From systematic analysis,it was inffered that the content of copper in the nanosheet was about 57-188 mg/g while the average thickness of the nanosheets Cu2O formed on ZrP is approximately 0.8 nm.The results of the minimal inhibitory concentration (MIC) revealed that an extremely low loading of Cu2O in Cu2O@ZrP nanosheet can lead to exceptional antibacterial activity.Examined on two various superbugs;i.e.methicillin-resistant staphylococcus aureus (MRSA) and vancomycin-resistant enterococcus (VRE),the composite nanosheet reagent performed over 99% microbial reduction.More intesetingly,the cell growth rate of the Cu2O@ZrP nanosheet was determined to be 20% lower than that of the neat Cu2O,manifesting a weaker cytotoxicity.This unique hybrid nanosheet with intriguing anti-superbug performance promises highly efficient protection for the fabrics,battledress,and medical textiles. | Jialiang Zhou Hengxue Xiang Fatemeh Zabihi Senlong Yu Bin Sun Meifang Zhu | 2019 | Nano Research2019，12，6： | 7 |

| 16 | The effect of aneurismal-wall mechanical properties on patient-specific hemodynamic simulations:two clinical case reports显示文摘Hemodynamic factors such as the wall shearstress play an important role in the pathogenesis and treatmentof cerebral aneurysms. In present study, we apply computationalfluid-structure interaction analyses on cerebralaneurysms with two different constitutive relations for aneur-ismalwall in order to investigate the effect of the aneur-ismal wall mechanical properties on the simulation results.We carry out these analyses by using two patient-specificmodels of cerebral aneurysms of different sizes located indifferent branches of the circle of Willis. The models areconstructed from 3D rotational angiography image data andblood flow dynamics is studied under physiologically representativewaveform of inflow. From the patient models analyzedin this investigation, we find that the deformations ofcerebral aneurysms are very small. But due to the nonlinearcharacter of the Navier-Stokes equations, these smalldeformations could have significant influences on the flowcharacteristics. In addition, we find that the aneurismal-wallmechanical properties have great effects on the deformationdistribution of the aneurysm, which also affects the wall shearstress distribution and flow patterns. Therefore, how to define a proper constitutive relation for aneurismal wall should beconsidered carefully in the hemodynamic simulation. | Jialiang Chen Shengzhang Wang Guanghong Ding Xinjian Yang Haiyun Li | 2009 | Acta Mechanica Sinica2009，25，5： | 7 |

| 18 | Improved MOEA/D for Dynamic Weapon-Target Assignment Problem显示文摘Conducting reasonable weapon-target assignment( WTA) with near real time can bring the maximum awards with minimum costs which are especially significant in the modern war. A framework of dynamic WTA( DWTA) model based on a series of staged static WTA( SWTA) models is established where dynamic factors including time window of target and time window of weapon are considered in the staged SWTA model. Then,a hybrid algorithm for the staged SWTA named Decomposition-Based Dynamic Weapon-target Assignment( DDWTA) is proposed which is based on the framework of multi-objective evolutionary algorithm based on decomposition( MOEA / D) with two major improvements: one is the coding based on constraint of resource to generate the feasible solutions, and the other is the tabu search strategy to speed up the convergence.Comparative experiments prove that the proposed algorithm is capable of obtaining a well-converged and well diversified set of solutions on a problem instance and meets the time demand in the battlefield environment. | Ying Zhang Rennong Yang Jialiang Zuo Xiaoning Jing | 2015 | Journal of Harbin Institute of Technology(New Series)2015，22，6： | 6 |
| 19 | WFRFT modulation recognition based on HOC and optimal order searching algorithm显示文摘A hybrid carrier(HC) scheme based on weighted-type fractional Fourier transform(WFRFT) has been proposed recently.While most of the works focus on HC scheme's inherent characteristics, little attention is paid to the WFRFT modulation recognition.In this paper, a new theory is provided to recognize the WFRFT modulation based on higher order cumulants(HOC). First, it is deduced that the optimal WFRFT received order can be obtained through the minimization of 4 th-order cumulants, C_(42). Then, a combinatorial searching algorithm is designed to minimize C_(42).Finally, simulation results show that the designed scheme has a high recognition rate and the combinatorial searching algorithm is effective and reliable. | LIANG Yuan DA Xinyu WU Jialiang XU Ruiyang ZHANG Zhe LIU Hujun | 2018 | Journal of Systems Engineering and Electronics2018，29，3： | 6 |
| 20 | The tectonic fracture modeling of an ultra-low permeability sandstone reservoir based on an outcrop analogy: A case study in the Wangyao Oilfield of Ordos Basin, China显示文摘Due to inherent limits of data acquisition and geophysical data resolution, there are large uncertainties in the characterization of subsurface fractures. However, outcrop analogies can provide qualitative and quantitative information on a large number of fractures, based on which the accuracy of subsurface fracture characterization can be improved. Here we take the tectonic fracture modeling of an ultra-low permeability sandstone reservoir based on an outcrop analogy, a case study of the Chang611 Formation of the Upper Triassic Yanchang Group of the Wangyao Oilfield in the Ordos Basin of China. An outcrop at the edge of the basin is a suitable analog for the reservoir, but the prerequisite is that they must have equivalent previous stress fields, similar final structural characteristics, relative timing and an identical depositional environment and diagenesis. The relationship among fracture density, rock type and bed thickness based on the outcrop is one of the most important fracture distribution models, and can be used to interpret fracture density in individual wells quantitatively. Fracture orientation, dip, geometry and scale, also should be described and measured in the outcrop, and can be used together with structure restoration and single well fracture density interpretation to guide fracture intensity prediction on bed surfaces and to constrain the construction of the 3D fracture geometry model of the subsurface reservoir. The application of the above principles shows the outcrop-based tectonic fracture models of the target ultra-low permeability sandstone reservoir are consistent with fractures inferred from microseismic interpretation and tracer tests. This illustrated that the fracture modeling based on the outcrop analogy is reliable and can reduce the uncertainty in stochastic fracture modeling. | Zhao Xiaoming Liu Li Hu Jialiang Zhou Xiaojun Li Min | 2014 | Petroleum Science2014，11，3： | 6 |
