1Research on the Heat Transfer Characteristics of a Loop Heat Pipe Used as Mainline Heat Transfer Mode for Spacecraft显示文摘An experimental research is conducted on the heat transfer characteristics of a loop heat pipe(LHP)used in the'mainline'heat transfer mode for spacecraft platform thermal control.The heat from multiple instruments scattered in different locations is collected by thermal control techniques such as axially grooved heat pipes and then transmitted to the radiant surface for dissipation through the LHP in an unified way.The research contents include the start-up characteristics,the operational stability characteristics,the operational blocking characteristics,the continuous blocking characteristics,the heat transfer capability,the thermal resistance,and the dynamic response characteristics under the change of the heat sink temperature.The results show that the higher the auxiliary starting power is,the easier it is to start the LHP;the higher the input power of the thermoelectric cooler is,the more beneficial it is to speed up the stabilization of the vapor-liquid interface in the condenser;the higher the blocking power,the shorter the blocking time of the LHP;the LHP can be operated stably within the heat sink temperature alteration process;the heat transfer ability is higher than 500 W with a systematic thermal resistance of 0.037℃/W.WANG Lu MIAO Jianyin GONG Mingming ZHOU Qiangu LIU Changu ZHANG Hongxing FAN Hanlin 2019Journal of Thermal Science2019,28,4:2
2Controlling Factors on Organic Matter Accumulation of Marine Shale across the Ordovician–Silurian Transition in South China: Constraints from Trace-Element Geochemistry显示文摘In recent years,significant progress in shale gas exploration has been achieved in the Upper Ordovician(Wufeng Formation)–Lower Silurian(Longmaxi Formation)shales in the Upper Yangtze area,South China.Although many studies have been carried out on the Upper Ordovician–Lower Silurian shales,the controlling factors causing organic matter accumulation of these shales remain controversial.This study uses trace-element geochemistry and sedimentological methods to evaluate terrigenous input,redox conditions and primary productivity to explore the mechanisms of organic matter accumulation.The variation of terrigenous fraction elements(Al,Th and Sc)concentrations reflect a mixed influence of sea-level change and weathering.The sea-level of the Upper Yangtze Sea went through two cycles of transgression to regression during the Ordovician–Silurian transition.The Linxiang Formation,Kuanyinchiao Bed and the upper part of Longmaxi Formation developed during the periods of regression,whereas the Wufeng Formation and the lower part of the Longmaxi Formation developed during the periods of transgression.The paleo-productivity indexes of TOC content,ratios of Ba/Al and P/Al,and redox conditions proxies of Mo concentration,ratios of U/Th and V/Cr generally display similar variation patterns with respect to the sea-level changes.High TOC contents and Ba/Al and P/Al ratios indicate the paleo-productivity was high on the sea surface,as shown by relatively good positive correlations between Th vs.TOC,and Sc vs.TOC.This indicates that the paleo-productivity was controlled by the nutrients input through weathering.The good positive correlations between redox conditions indexes(U/Th and V/Cr ratios)with TOC content reflects reductive preservation conditions(anoxic to euxinic),thus implying they were an important controlling factor for organic matter accumulation.Nevertheless,redox conditions were closely associated with sea level change and organic matter decomposition.Therefore,the sea-level change and weathering were the primary controlling factors for organic matter enrichment across the Ordovician to Silurian transition.Zhen Qiu Huifei Tao Bin Lu Zhenhong Chen Songtao Wu Hanlin Liu Junli Qiu 2021Journal of Earth Science2021,32,4:2

5Evaluation of the relative γ-ray intensities emitted from ^(56)Co and ^(66)Ga显示文摘56Co and 66Ga with γ-ray energies covering the range of 0.84-3.55 and 0.68-4.81MeV, respectively, are important radionuclides for Ge detector calibration. The newly evaluated relative γ-ray intensities were recommended using the measurements finished after 2000 year by Baglin and Browne in 2004. In 2005 China groups measured the relative γ-ray intensities. The China measurements were about 2% systematically lower than other measurements and these evaluations. In this paper the discrepancies among these measurements and the evaluations are analyzed carefully and the new evaluations are re-recommended.YU Weixiang HUANG Xiaolong CHEN Xiongjun LU Hanlin 2009Nuclear Science and Techniques2009,20,6:1

7Numerical investigation of the effects of turbulence on the ignition process in a turbulent MILD flame显示文摘In this study,we conduct three-dimensional nonlinear large-eddy simulation to investigate the interaction between turbulence and reaction during the initial ignition process of a turbulent methane/hydrogen jet-in-hot-coflow flame under moderate or intense low-oxygen dilution(MILD)condition.Special focus has been placed on the spatial development of the flame and the temporal evolution of representative ignition spots that characterize the range of ignition behaviors observed in the case.Results show that the ignition process of the flame consists of four consecutive phases.Ignition occurs initially with relatively lean mixtures,and compared to the corresponding homogeneous stagnant adiabatic combustion,the loss of radical species associated with flow transportation causes a delay in ignition.The initial ignition spots formed during the autoignition phase provide sufficient conditions for the stabilization of the flame,including the provision of a variety of key radicals.Results also show that the flow convection accompanying the hot coflow dominated the slow flame propagation,and the turbulent mixing is of great importance for rapid flame propagation.These findings will broaden our knowledge of MILD combustion and provide useful insights into advanced ignition contr.Xiang Qian Hao Lu Chun Zou Hanlin Zhang Shujing Shao Hong Yao 2021Acta Mechanica Sinica2021,37,8:1

11Security Analysis of Secret Image Sharing显示文摘Differently from pure data encryption,secret image sharing(SIS)mainly focuses on image protection through generating a secret image into n shadow images(shares)distributed to n associated participants.The secret image can be reconstructed by collecting sufficient shadow images.In recent years,many SIS schemes are proposed,among which Shamir’s polynomial-based SIS scheme and visual secret sharing(VSS)also called visual cryptography scheme(VCS)are the primary branches.However,as the basic research issues,the security analysis and security level classification of SIS are rarely discussed.In this paper,based on the study of image feature and typical SIS schemes,four security levels are classified as well as the security of typical SIS schemes are analyzed.Furthermore,experiments are conducted to evaluate the efficiency of our analysis by employing illustrations and evaluation metrics.Xuehu Yan Yuliang Lu Lintao Liu Song Wan Wanmeng Ding Hanlin Liu 2017国际计算机前沿大会会议论文集2017,,1:0
12Coordinating Zirconium Nodes in Metal-Organic Framework with Trifluoroacetic Acid for Enhanced Lewis Acid Catalysis显示文摘Regulating Lewis acid sites with well-defined electronic state and steric environment is still challenging for achieving high catalytic efficiency.Here we show coordinating zirconium nodes in the typical metal-organic framework known as MOF-545 with the monocarboxylate modulators including trifluoroacetic acid(TFA)or benzoic acid(BA)over meso-tetra(4-carboxyphenyl)-porphine(H_(2)TCPP),denoted as MOF-545-TFA or MOF-545-BA.Impressively,MOF-545-TFA shows the significantly enhanced performance for the catalytic ring-opening reaction of various epoxides with alcohols and good recyclability at 40°C in respect with MOF-545-BA and ZrO_(2).This mainly originates from the stronger Lewis acidity and more active zirconium sites induced by the electron-withdrawing TFA,resulting in the increased ability for activation of epoxides.This modulation approach is promising for enlarging the toolbox to extend the MOFs-based Lewis acid catalysis.WANG Wenyang LIU Hanlin YANG Caoyu FAN Ting CUI Chengqian LU Xiaoquan TANG Zhiyong LI Guodong 2022Chemical Research in Chinese Universities2022,38,5:0

15Status of an MWth integrated gasification fuel cell powergeneration system in China显示文摘Abstract Here,we provide a status update of an integrated gasification fuel cell(IGFC)power-generation system being developed at the National Institute of Clean-and-Low-Carbon in China at the megawatt thermal(MWth)scale.This system is designed to use coal as fuel to produce syngas as a first step,similar to that employed for the integrated gasification combined cycle.Subsequently,the solid-oxide fuel-cell(SOFC)system is used to convert chemical energy to electricity directly through an electrochemical reaction without combustion.This system leads to higher efficiency as compared with that from a traditional coal-fired power plant.The unreacted fuel in the SOFC system is transported to an oxygencombustor to be converted to steam and carbon dioxide(CO_(2)).Through a heat-recovery system,the steam is condensed and removed,and CO_(2) is enriched and captured for sequestration or utilization.Comprehensive economic analyses for a typical IGFC system was performed and the results were compared with those for a supercritical pulverized coal-fired power plant.The SOFC stacks selected for IGFC development were tested and qualified under hydrogen and simulated coal syngas fuel.Experimental results using SOFC stacks and thermodynamic analyses indicated that the control of hydrogen/CO ratio of syngas and steam/CO ratio is important to avoid carbon deposition with the fuel pipe.A 20-kW SOFC unit is under development with design power output of 20 kW and DC efficiency of 50.41%.A 100 kW-level subsystem will consist of 6920-kW power-generation units,and the MWth IGFC system will consist of 59100 kWlevel subsystems.Chang Wei Zhien Liu Chufu Li Surinder Singh Haoren Lu Yudong Gong Pingping Li Hanlin Wang Xia Yang Ming Xu Shujun Mu 2021International Journal of Coal Science & Technology2021,8,3:0
16Secret Data-Driven Carrier-Free Secret Sharing Scheme Based on Error Correction Blocks of QR Codes显示文摘In this paper,a novel secret data-driven carrier-free(semi structural formula)visual secret sharing(VSS)scheme with(2,2)threshold based on the error correction blocks of QR codes is investigated.The proposed scheme is to search two QR codes that altered to satisfy the secret sharing modules in the error correction mechanism from the large datasets of QR codes according to the secret image,which is to embed the secret image into QR codes based on carrier-free secret sharing.The size of secret image is the same or closest with the region from the coordinate of(7,7)to the lower right corner of QR codes.In this way,we can find the QR codes combination of embedding secret information maximization with secret data-driven based on Big data search.Each output share is a valid QR code which can be decoded correctly utilizing a QR code reader and it may reduce the likelihood of attracting the attention of potential attackers.The proposed scheme can reveal secret image visually with the abilities of stacking and XOR decryptions.The secret image can be recovered by human visual system(HVS)without any computation based on stacking.On the other hand,if the light-weight computation device is available,the secret image can be lossless revealed based on XOR operation.In addition,QR codes could assist alignment for VSS recovery.The experimental results show the effectiveness of our scheme.Song Wan Yuliang Lu Xuehu Yan Hanlin Liu Longdan Tan 2017国际计算机前沿大会会议论文集2017,,1:0
17Room-temperature multiple ligands-tailored SnO_(2) quantum dots endow in situ dual-interface binding for upscaling efficient perovskite photovoltaics with high V_(OC)显示文摘The benchmark tin oxide(SnO_(2))electron transporting layers(ETLs)have enabled remarkable progress in planar perovskite solar cell(PSCs).However,the energy loss is still a challenge due to the lack of“hidden interface”control.We report a novel ligand-tailored ultrafine SnO_(2) quantum dots(QDs)via a facile rapid room temperature synthesis.Importantly,the ligand-tailored SnO_(2) QDs ETL with multi-functional terminal groups in situ refines the buried interfaces with both the perovskite and transparent electrode via enhanced interface binding and perovskite passivation.These novel ETLs induce synergistic effects of physical and chemical interfacial modulation and preferred perovskite crystallization-directing,delivering reduced interface defects,suppressed non-radiative recombination and elongated charge carrier lifetime.Power conversion efficiency(PCE)of 23.02%(0.04 cm^(2))and 21.6%(0.98 cm^(2),V_(OC) loss:0.336 V)have been achieved for the blade-coated PSCs(1.54 eV E_(g))with our new ETLs,representing a record for SnO_(2) based blade-coated PSCs.Moreover,a substantially enhanced PCE(V_(OC))from 20.4%(1.15 V)to 22.8%(1.24 V,90 mV higher V_(OC),0.04 cm^(2) device)in the blade-coated 1.61 eV PSCs system,via replacing the benchmark commercial colloidal SnO_(2) with our new ETLs.Zhiwei Ren Kuan Liu Hanlin Hu Xuyun Guo Yajun Gao Patrick W.K.Fong Qiong Liang Hua Tang Jiaming Huang Hengkai Zhang Minchao Qin Li Cui Hrisheekesh Thachoth Chandran Dong Shen Ming-Fai Lo Annie Ng Charles Surya Minhua Shao Chun-Sing Lee Xinhui Lu Frédéric Laquai Ye Zhu Gang Li 2021Light(Science & Applications)2021,10,12:0

20Multiscale tensegrity model for the tensile properties of DNA nanotubes显示文摘DNA nanotubes(DNTs)with user-defined shapes and functionalities have potential applications in many fields.So far,compared with numerous experimental studies,there have been only a handful of models on the mechanical properties of such DNTs.This paper aims at presenting a multiscale model to quantify the correlations among the pre-tension states,tensile properties,encapsulation structures of DNTs,and the surrounding factors.First,by combining a statistical worm-like-chain(WLC)model of single DNA deformation and Parsegian's mesoscopic model of DNA liquid crystal free energy,a multiscale tensegrity model is established,and the pre-tension state of DNTs is characterized theoretically for the first time.Then,by using the minimum potential energy principle,the force-extension curve and tensile rigidity of pre-tension DNTs are predicted.Finally,the effects of the encapsulation structure and surrounding factors on the tensile properties of DNTs are studied.The predictions for the tensile behaviors of DNTs can not only reproduce the existing experimental results,but also reveal that the competition of DNA intrachain and interchain interactions in the encapsulation structures determines the pre-tension states of DNTs and their tensile properties.The changes in the pre-tension states and environmental factors make the monotonic or non-monotonic changes in the tensile properties of DNTs under longitudinal loads.Hanlin LIU Nenghui ZHANG Wei LU 2023Applied Mathematics and Mechanics(English Edition)2023,44,3:0
