| 1 | Effects of(Mg_(1/3)Sb_(2/3))^(4+)substitution on the structure and microwave dielectric properties of Ce_(2)Zr_(3)(MoO_(4))_(9) ceramics显示文摘Ce2[Zr_(1-x)(Mg_(1/3)Sb_(2/3))_(x)]_(3)(MoO_(4))_(9)(0.02≤x≤0.10)ceramics were prepared by the traditional solid-state method.A single phase,belonging to the space group of R3c,was detected by using X-ray diffraction at the sintering temperatures ranging from 700 to 850℃.The microstructures of samples were examined by applying scanning electron microscopy(SEM).The crystal structure refinement of these samples was investigated in detail by performing the Rietveld refinement method.The intrinsic properties were calculated and explored via far-infrared reflectivity spectroscopy.The correlations between the chemical bond parameters and microwave dielectric properties were calculated and analyzed by Phillips-van Vechten-Levine(P-V-L)theory.Ce_(2)[Zr_(0.94)(Mg_(1/3)Sb_(2/3))_(0.06)]_(3)(Mo0_(4))_(9)ceramics with excellent dielectric properties were sintered at 725℃for 6 h(εr=10.37,Q×f=71,748 GHz,andτf=-13.6 ppm/℃,εr is the dielectric constant,τf is the quality factor,and rf is the temperature coefficient of resonant frequency). | Xu ZHOU Lintao LIU Jiajia SUN Ningkang ZHANG Huazhang SUN Haitao WU Wenhong TAO | 2021 | Journal of Advanced Ceramics2021,10,4: | 4 |
| 2 | Quantitative effects of phase transition on solute partition coefficient,inclusion precipitation, and microsegregation for high-sulfur steel solidification显示文摘Segregation and inclusion precipitation are the common behaviours of steel solidification, which are resulted from the redistribution and diffusion of the solute elements at the solid-liquid interface. The effect of the phase transition of high-sulfur free-cutting steel is quantified in the present work for the solute partition coefficient(ki), inclusion precipitation, and microsegregation by establishing a coupling model of microsegregation and inclusion precipitation, wherein the quantified dependencies of ki in terms of temperature, phase and carbon(C) content were applied. Results showed that the solidification temperature range and phase transition of high-sulfur steel that under different solidification paths and C contents were quite different, leading to differences in ki and eventually in microsegregation. kC,kP, and kS were mainly affected by phase composition and kSi was primarily by temperature, while kMn depended on both phase composition and temperature during solidification. Increasing the C content within the interval 0.07-0.48 wt%, the ‘proportion of the δ phase maintained temperature region during solidification’(Pδ), kave Pand kave S(kiave, the average value of the ki across the whole stages of solidification)decreased monotonically, whereas kave Cincreased linearly. The peritectic reaction impacted on the phase composition and ki, leading to the change in microsegregation. Such effect of the peritectic reaction was more significant at the last stage of solidification. When the Pδ was between 75% and 100%(corresponding to 0.07-0.16 wt% C), the solidification path resulted in a greater effect on the microsegregation of solutes C, P, and S because of the peritectic reaction. The microsegregation of solutes Mn and S were comprehensively influenced by kMn, kS and Mn S precipitation as well. The studies would help reveal the solute redistribution at the solid-liquid interface, and improve the segregation of high-sulfur steel by controlling the solidification and precipitation in practice. | Lintao Gui Mujun Long Shixin Wu Zhihua Dong Dengfu Chen Yunwei Huang Huamei Duan Levente Vitos | 2019 | Journal of Materials Science & Technology2019,35,10: | 3 |
| 3 | The Distribution of Petroleum Resources and Characteristics of Main Petroliferous Basins along the Silk Road Economic Belt and the 21st-Century Maritime Silk Road显示文摘The Silk Road Economic Belt and the 21st-century Maritime Silk Road Initiative,abbreviated as the Belt and Road Initiative,is a primary development strategy of China's future international cooperation.Especially,the energy resource cooperation,including oil and gas resources cooperation,is an important part of this initiative.The Belt and Road has undergone complicated geological evolution,and contains abundant mineral resources such as oil,gas,coal,uranium,iron,copper,gold and manganese ore resources.Among these,Africa holds 7.8% of the world's total proven oil reserves.The oil and gas resources in Africa are relatively concentrated,with an overall low exploration degree and small consumption demand.Nigeria and Libya contain the most abundant oil resources in Africa,accounting for 2.2%and 2.9%of the world's total reserves,respectively.Nigeria and Algeria hold the richest natural gas resources in Africa,occupying 2.8%and 2.4%of the world's total reserves,respectively.Africa's oil and gas resources are mainly concentrated in Egypt,Sultan and Western Sahara regions in the northern Africa,and the Gulf of Guinea,Niger River and Congo River area in the western Africa.The Russia-Central Asia area holds rich petroleum resources in Russia,Kazakhstan,Turkmenistan and Uzbekistan.The potential oil and gas areas include the West Siberia Basin,East Siberia Basin and sea continental shelf in Russia,the northern and central Caspian Basin in Kazakhstan,the right bank of the Amu-Darya Basin,the East Karakum uplift and the South Caspian Basin in Turkmenistan,and the Amu-Daria Basin,Fergana Basin,Afghan-Tajik Basin and North Ustyurt Basin in Uzbekistan.The Middle East oil and gas resources are mainly distributed in the Zagros foreland basin and Arabian continental margin basin,and the main oil-producing countries include Saudi Arabia,Iran and Iraq.The Asia Pacific region is a new oil and gas consumption center,with rapid growth of oil and gas demand.In 2012,this region consumed about 33.6%of the world's total oil consumption and 18.9%of the world's total natural gas consumption,which has been ranked the world's largest oil and gas consumption center.The oil and gas resources are concentrated in China,Indosinian,Malaysia,Australia and India.The abundant European proven crude oil reserves are in Norway,Britain and Denmark and also rich natural gas resources in Norway,Holland and Britain.Norway and Britain contain about 77.5%of European proven oil reserves,which accounts for only 0.9%of the world's proven reserves.The Europe includes main petroliferous basins of the Voring Basin,Anglo-Dutch Basin,Northwest German Basin,Northeast German-Polish Basin and Carpathian Basin.According to the analysis of source rocks,reservoir rocks,cap rocks and traps for the main petroliferous basins,the potential oil and gas prospecting targets in the Belt and Road are mainly the Zagros Basin and Arabic Platform in the Middle East,the East Barents Sea Basin and the East Siberia Basin in Russia-Central Asia,the Niger Delta Basin,East African rift system and the Australia Northwest Shelf.With the development of oil and gas theory and exploration technology,unconventional petroleum resources will play an increasingly important role in oil and gas industry. | HAO Qingqing ZUO Yinhui LI Lintao CHEN Weijun YI Junjie WU Lei | 2017 | Acta Geologica Sinica(English Edition)2017,91,4: | 3 |
| 4 | Structure characteristics and microwave dielectric properties of Pr_(2)(Zr_(1-x)Ti_(x))_(3)(MoO_(4))_(9) solid solution ceramic with a stable temperature coefficient显示文摘Pr_(2)(Zr_(1−x)Ti_(x))_(3)(MoO_(4))_(9)(x=0.1-1.0)ceramics were prepared via a conventional solid-state method,the dependence of crystal structure and bond characteristics on microwave dielectric properties was investigated systemically.The X-ray diffraction patterns indicated that the single-phase Pr_(2)Zr_(3)(MoO_(4))_(9)structure was formed in all the specimens.As the Ti^(4+)content increased,the lattice volume gradually decreased,which was ascribed to the fact that the ionic radius of Ti^(4+)was smaller than that of Zr^(4+).Notably,outstanding microwave dielectric properties withεr of 10.73-16.35,Q·f values of 80,696-18,726 GHz and minorτ_(f) values−14.1-−2.6 ppm/℃were achieved in Pr_(2)(Zr_(1−x)Ti_(x))_(3)(MoO_(4))_(9)ceramics.Theε_(r) increased with the rising x values,which was associated with the increase ofα/Vm values.The decreasing Q·f was affected by the decline of lattice energy of[Zr/TiO_(6)]octahedral.Theτf value was dominated by[Zr/TiO_(6)]octahedral distortion,Mo-O bond energy,bond strength and B-site bond valence.Furthermore,infrared reflection spectra suggested that the properties were mainly caused by the absorption of phonon,and the dielectric loss could be further reduced by optimizing the experimental process. | Huanrong Tian Jinjie Zheng Lintao Liu Haitao Wu Hideo Kimura Yizhong Lu Zhenxing Yue | 2022 | Journal of Materials Science & Technology2022,,21: | 3 |

| 6 | Petroleum Distribution Characteristics of the Americas and the Exploration Prospect Analysis显示文摘The world's present demand for oil and gas is still in a rapid growth period, and traditional oil and gas resources account for more than 60% of the global oil and gas supply. The Americas is the world's second largest production and consumption center of liquid fuel, and is also the world's largest natural gas producer. In 2016, the Americas had 85.3 billion tons of proven oil reserves and 18.7 trillion m^3 of proven natural gas reserves, which account for 35.4% and 10.0% of world's total reserves, respectively. It produced 1267.1 Mt of oil and 1125.4 billion m^3 of natural gas, which account for 28.9% and 31.7% of the world's total production, respectively. The crude oil and natural gas reserves are mainly distributed in the U.S., Canada and Venezuela. The U.S. is the earliest and most successful country in shale gas exploration and development, and its shale gas is concentrated in the southern, central and eastern U.S., including the Marcellcus shale, Barnett shale, Eagle Ford shale, Bakken shale, Fayettevis shale, Haynsvill shale, Woodford shale and Monterey/Santos shale. The potential oil and gas resources in the Americas are mainly concentrated in the anticline and stratigraphic traps in the MiddleUpper Jurassic slope deposition of the North Slope Basin, the Paleozoic Madsion group dolomite and limestone in the Williston Basin, dominant stratigraphic traps and few structural traps in the Western Canada Sedimentary Basin, the Eocene structural-stratigraphic hydrocarbon combination, structuralunconformity traps and structural hydrocarbon combination, and the Upper Miocene stratigraphicstructural hydrocarbon combination in the Maracaibo Basin of Venezuela, the stratigraphic-structural traps and fault horst, tilting faulted blocks and anticlines related to subsalt structure and basement activity in the Campos Basin, the subsalt central low-uplift belt and supra-salt central low-uplift belt in the Santos Basin of Brazil, and the structural-stratigraphic traps in the Neuquen Basin of Argentina. In addition, the breakthrough of seismic subsalt imaging technology makes the subsalt deepwater sea area of eastern Barzil an important oil and gas potential area. | HAO Qingqing LI Lintao ZUO Yinhui CHEN Weijun WU Lei YI Junjie | 2018 | Acta Geologica Sinica(English Edition)2018,92,1: | 1 |
| 7 | Effects of Flexible Conjugation-Break Spacers of Non-Conjugated Polymer Acceptors on Photovoltaic and Mechanical Properties of All-Polymer Solar Cells显示文摘All-polymer solar cells(all-PSCs)possess attractive merits including superior thermal stability and mechanical flexibility for large-area roll-to-roll processing.Introducing flexible conjugation-break spacers(FCBSs)into backbones of polymer donor(P_(D))or polymer acceptor(P_(A))has been demonstrated as an efficient approach to enhance both the photovoltaic(PV)and mechanical properties of the all-PSCs.However,length dependency of FCBS on certain all-PSC related properties has not been systematically explored.In this regard,we report a series of new non-conjugated P_(A)s by incorporating FCBS with various lengths(2,4,and 8 carbon atoms in thioalkyl segments).Unlike com-mon studies on so-called side-chain engineering,where longer side chains would lead to better solubility of those resulting polymers,in this work,we observe that the solubilities and the resulting photovoltaic/mechanical properties are optimized by a proper FCBS length(i.e.,C2)in P_(A) named PYTS-C2.Its all-PSC achieves a high efficiency of 11.37%,and excellent mechanical robustness with a crack onset strain of 12.39%,significantly superior to those of the other P_(A)s.These results firstly demonstrate the effects of FCBS lengths on the PV performance and mechanical properties of the all-PSCs,providing an effective strategy to fine-tune the structures of P_(A)s for highly efficient and mechanically robust PSCs. | Qiaonan Chen Yung Hee Han Leandro R.Franco Cleber F.N.Marchiori Zewdneh Genene CMoyses Araujo Jin-Woo Lee Tan Ngoc-Lan Phan Jingnan Wu Donghong Yu Dong Jun Kim Taek-Soo Kim Lintao Hou Bumjoon J.Kim Ergang Wang | 2022 | Nano-Micro Letters2022,14,10: | 1 |
| 8 | Protection Performance of Plasma Sprayed Al_(2)O_(3)-13 wt%TiO_(2) Coating Sealed with an Organic-inorganic Hybrid Agent显示文摘An organic-inorganic hybrid sealing agent was fabricated and used in the plasma sprayed Al_(2)O_(3)-13 wt%TiO_(2)coating,and conventional silicone agent was also used for comparison.Protection performance of the coatings was comprehensively evaluated based on both anti-corrosion and anti-biofouling properties.The results reveal that the sealing treatment is remarkably useful to decrease the porosity of the coating,and the porosity of the coating sealed with the hybrid agent is only 0.035%.Immersion corrosion test and Tafel polarization test reveal that the sealed coating with the hybrid agent exhibits a better corrosion resistance by compared with the coating sealed with silicone agent.The corrosion current density i_(corr) of the hybrid agent sealed coating is only 0.7×10^(-6)A·cm^(-2).Moreover,anti-biofouling tests both in the outdoor analogue hydraulic environment and in the natural marine environment prove that the mentioned novel coating presents a better combination of corrosion resistance and anti-biofouling property by compared with the other coatings,and it could be used as a protection of metal components in the marine environment. | 张凯城 周泽华 DENG Yong WANG Guangyu WANG Zehua WU Lintao YANG Guangheng | 2022 | Journal of Wuhan University of Technology(Materials Science)2022,37,3: | 1 |

| 13 | Rim-differentiated pillar[5]arenes显示文摘Pillar[5]arenes,designed and prepared by Ogoshi et al.in 2008 initially,refer to fifth classical macrocyclics.Among a wide range of pillar[5]arenes,rim-differentiated pillar[5]arenes containing five identical substituents on one rim and five different identical groups on the other rims are considered the most noteworthy type of pillar[5]arenes.As compared with the perfunctionalized pillar[5]arene,the self-assembly properties of rim-differentiated pillar[5]arenes have more varieties.On the other hand,in comparison with other types of pillar[5]arenes,the rim-differentiated pillar[5]arenes exhibit a more rigid symmetrical structure.In the present review,the synthetic methods,host-guest interactions,self-assembly properties and applications of rim-differentiated pillar[5]arenes are summarized.Hopefully,this review will be conducive to researchers in macrocyclic supramolecular chemistry. | Lintao Wu Chun Han Xiaobi Jing Yong Yao | 2021 | Chinese Chemical Letters2021,32,11: | 0 |
| 14 | Step-edge controlled fast growth of wafer-scale MoSe_(2)films by MOCVD显示文摘Two-dimensional(2D)transition metal dichalcogenides(TMDCs),due to their unique physical properties,have a wide range of applications in the next generation of electronics,optoelectronics,and valleytronics.Large-scale preparation of high-quality TMDCs films is critical to realize these potential applications.Here we report a study on metal-organic chemical vapor deposition(MOCVD)growth of wafer-scale MoSe_(2)films guided by the crystalline step edges of miscut sapphire wafers.We established that the nucleation density and growth rate of MoSe_(2)films were positively correlated with the step-edge density and negatively with the growth temperature.At a certain temperature,the MoSe_(2)domains on the substrate with high step-edge density grow faster than that with low density.As a result,wafer-scale and continuous MoSe_(2)films can be formed in a short duration(30 min).The MoSe_(2)films are of high crystalline quality,as confirmed by systematic Raman and photoluminescence(PL)measurements.The results provide an important methodology for the rapid growth of wafer-scale TMDCs,which may promote the application of 2D semiconductors. | Rui Ji Jing Liao Lintao Li Rongji Wen Mengjie Liu Yifeng Ren Jianghua Wu Yunrui Song Minru Qi Zhixing Qiao Liwei Liu Chengbing Qin Yu Deng Yongtao Tian Suotang Jia Yufeng Hao | 2023 | Nano Research2023,16,7: | 0 |
