| 1 | Thermodynamic analyses and optimization for thermoelectric devices:The state of the arts显示文摘Thermoelectric effect is the most efficient way to convert electric energy directly from the temperature gradient. Thermoelectric effect-based power generation, cooling and heating devices are solid-stated, environmentally friendly, reliable, long-lived, easily maintainable, and easy to achieve miniaturization and integration. So they have unparalleled advantages in the aerospace, vehicle industry, waste heat recovery, electronic cooling, etc. This paper reviews the progress in thermodynamic analyses and optimizations for single- and multiple-element, single- and multiple-stage, and combined thermoelectric generators, thermoelectric refrigerators and thermoelectric heat pumps, especially in the aspects of non-equilibrium thermodynamics and finite time thermodynamics. It also discusses the developing trends of thermoelectric devices, such as the heat sources of thermoelectric generators, multi-stage thermoelectric devices, combined thermoelectric devices, and heat transfer enhancement of thermoelectric devices. | CHEN LinGen MENG FanKai SUN FengRui | 2016 | Science China(Technological Sciences)2016，59，3： | 45 |
| 2 | Performance optimization of a class of combined thermoelectric heating devices显示文摘A detailed model of thermally-driven combined thermoelectric(TE) heating device is established. The device consists of twostage TE heat pump(TTEH) and two-stage TE generator(TTEG) with four external heat exchangers(HEXs). Both internal losses and external heat transfer irreversibilities are considered in the model. The heating capacity and the coefficient of performance(COP) of the device are improved through numerical optimization,which is of great significance to the application of the device. The distribution of the total TE element number among four TE devices and the distribution of the total external heat conductance among the four external HEXs are optimized. The results show that both the reservoir temperatures of TTEG and TTEH have significant influences on the performance and the corresponding optimum parameters of the device. The COP can reach 0.14 after optimization when the temperature difference of heat source is 150 K and the temperature difference of heating is 10 K. | CHEN LinGen MENG FanKai GE YanLin FENG HuiJun XIA ShaoJun | 2020 | Science China(Technological Sciences)2020，63，12： | 10 |
| 3 | Influences of external heat transfer and Thomson effect on the performance of TEG-TEC combined thermoelectric device显示文摘A thermodynamic model of a thermoelectric generator(TEG)-driven thermoelectric cooler(TEC) device considering Thomson effect and external heat transfer(HT) is established based on the combination of non-equilibrium and finite time thermodynamic theories. The expressions of cooling capacity and coefficient of performance(COP) are obtained. Performances are compared with and without considering Thomson effect using numerical optimization method. The influences of Thomson effect on the optimal performances, optimum allocations of thermoelectric(TE) element number and HT surface area are discussed. The results indicate that Thomson effect decreases the maximum cooling capacity and COP. More TE elements should be allocated to TEG, and more HT area should be allocated to the heat exchanger(HEX) of TEG, the hot-side HEX of TEG and the cold-side HEX of TEC in the design of the device considering Thomson effect. The results obtained can be used to help design TEG-TEC devices. | FENG YuanLi CHEN LinGen MENG FanKai SUN FengRui | 2018 | Science China(Technological Sciences)2018，61，10： | 8 |

| 13 | Leakage detection of oil tank using terahertz spectroscopy显示文摘The necessity for safety in oil-gas storage and transportation has led to increasing technical requirements for on-line monitoring of damaged pores and oil leakage from tanks. In this study, the severity of damage of the oil tank at the micron level was detected by terahertz time-domain spectroscopy(THz-TDS), which is of great significance for the early detection and prevention of oil leakage. The THz amplitude(EP) was related to the severity of damaged according to the THz-TDS measurement of oil tanks with various degrees of damage, including intact, partially damaged, completely damaged, and seriously damaged points.Absorption and scattering effects co-occurred when the THz wave penetrated the tanks, with the collective tendencies being used to expressly monitor oil leakage from tanks. When the oil tank was damaged to form micron-level pores and the crude oil had not overflowed, the pore size was close to THz wavelength and the Mie scattering effect was obvious. After further destruction of the pores, the crude oil gradually spilled over and the scattering effect was gradually transformed from Mie scattering to Rayleigh scattering. In addition, the polar molecules in crude oil have strong resonance under the irradiation of THz wave, and the THz wave has strong attenuation. Eventually, surface tension of the oil flattens the surface of the tank, the scattering effect is gradually suppressed and replaced by the absorption effect. Absorption and scattering caused by THz waves passing through tanks coexist and have competing relationships. The change rule of EPcan successfully prove the phenomenon and can be considered as an important alternative for application to predict the degree of tank damage. Therefore, in this study, the detection of pores as small as micrometers on the oil tank was expected to greatly prevent oil leakage accidents and improve the safety of oil and gas storage and transportation. | QIN FanKai CHEN SiTong CHEN Ru ZHAN HongLei MIAO XinYang XIANG WenFeng ZHAO Kun | 2021 | Science China(Technological Sciences)2021，64，9： | 1 |
| 14 | APPROACH FOR MODULE PARTITION OF BLOCKS IN SHIPBUILDING显示文摘To manage the complexities of hull module partitions,a new approach to the partitions of hierarchical modules for shipbuilding is proposed. Based on the assembly and manufacture process, the approach determines the hierarchy and basis of the module partition first,and then according to the type of connection between the parts of the block module,the degree of membership for the rational connection is gained and the fuzzy relation matrix between different parts is then established.The fuzzy clustering technique is used to partition the modules,and then the method of fuzzy comprehensive assessment is used to choose a relative reasonable scheme.A case study has been conducted,which proves that the approach is feasible and applicable;Especially it obtains the sub-module partition,which sets up the shipbuilding process at a higher-level assembly and has offered effective tools for the modular ship design. | TENG Xiaoyan KONG Fankai ZHANG Jiatai | 2008 | Chinese Journal of Mechanical Engineering2008，21，2： | 1 |

| 16 | A New Species of Ginkgo with Male Cones and Pollen Grains in situ from the Middle Jurassic of Eastern Xinjiang,China显示文摘Well-preserved Ginkgo pollen organs are analyzed from the Middle Jurassic Xishanyao Formation of the Turpan–Hami Basin, Xinjiang Uygur Autonomous Region, northwestern China, and are described as a new species, Ginkgo hamiensis Z.X. Wang et B.N. Sun sp. nov. The immature male cones are cylindrical and catkin-like, with two longitudinal stripes on the stalk. The pollen sacs are shaped like a long oval with two pollen sacs fused together for each microsporophyll, and the microsporophyll tip is a triangular cystidium. The pollen grains are oblong or fusiform and monocolpate; both ends are blunt or sharp. By comparison with previously reported fossil records of Ginkgo plants, we determined that the current fossils are different from all other reported species; thus, the present fossil is referred to as a new species of Ginkgo. The reproductive organs of the Ginkgo fossils described herein can provide valuable information for the study of Ginkgo plants. Further, there are two probable evolutionary trends in the Ginkgo pollen cones. One trend is that the number of pollen sacs changed from three or four during the Jurassic and Cretaceous to two at the present day; the other is that the number of pollen sacs has remained two from the Middle Jurassic to the present day. In addition, the pollen cones described herein are similar to the pollen cones of the extant Ginkgo, which strongly indicates that the morphology of Ginkgo plants may have remained highly conserved over millions of years. | WANG Zixi SUN Fankai JIN Peihong CHEN Yingquan CHEN Jingwei DENG Peng YANG Guolin SUN Bainian | 2017 | Acta Geologica Sinica(English Edition)2017，91，1： | 0 |
| 17 | Strength Acquisition Mechanism of High Temperature Resistant Materials Prepared by Waste Architectural Ceramics显示文摘In order to realize the large-scale and high-value utilization of waste architectural ceramics,high-temperature resistant materials based on waste architectural ceramics were prepared with sodium silicate as the binder,clay/bauxite and metakaolin/bauxite as coating materials,and the cold strength obtaining mechanism was explored.The phase composition,the microstructure and the mechanical properties of the high temperature resistant materials based on waste architectural ceramics were tested and analyzed.The results showed that when the heat treatment temperature was between 110-1000℃,the strength of the samples mainly came from the physical adhesion of sodium silicate and fine powder.When the temperature rose to 1100℃,the strength of the sample was improved since the internal low-melting-point components melted and promoted sintering.The addition of clay and bauxite can effectively enhance the flexural strength of the samples when the heat treatment temperature is 1000℃.When the heat treatment temperature rises from 900 to 1000℃,the flexural strength of the samples will be enhanced owing to the formation of silica alumina spinel and mullite from metakaolin. | HUANG Zhaohui SHI Tengteng LIU Yangai WU Xiaowen LIU Xianjie LIN Fankai LENG Gouqin ZHAN Huasheng LI Yanjing GAO Changhe | 2022 | China's Refractories2022，31，1： | 0 |
| 18 | Towards intrinsically pure graphene grown on copper显示文摘The state-of-the-art semiconductor industry is built on the successful production of silicon ingot with extreme purity as high as 99.999999999%,or the so-called'eleven nines'.The coming high-end applications of graphene in electronics and optoelectronics will inevitably need defect-free pure graphene as well.Due to its two-dimensional(2D)characteristics,graphene restricts all the defects on its surface and has the opportunity to eliminate all kinds of defects,i.e.,line defects at grain boundaries and point or dot defects in grains,and produce intrinsically pure graphene.In the past decade,epitaxy growth has been adopted to grow graphene by seamlessly stitching of aligned grains and the line defects at grain boundaries were eliminated finally.However,as for the equally common dot and point defects in graphene grain,there are rare ways to detect or reduce them with high throughput and efficiency.Here,we report a methodology to realize the production of ultrapure graphene grown on copper by eliminating both the dot and point defects in graphene grains.The dot defects,proved to be caused by the silica particles shedding from quartz tube during the high-temperature growth,were excluded by a designed heat-resisting box to prevent the deposition of particles on the copper surface.The point defects were optically visualized by a mild-oxidation-assisted method and further reduced by etching-regrowth process to an ultralow level of less than 1/1,000 μm^(2).Our work points out an avenue for the production of intrinsically pure graphene and thus lays the foundation for the large-scale graphene applications at the integrated-circuit level. | Xiaozhi Xu Ruixi Qiao Zhihua Liang Zhihong Zhang Ran Wang Fankai Zeng Guoliang Cui Xiaowen Zhang Dingxin Zou Yi Guo Can Liu Ying Fu Xu Zhou Muhong Wu Zhujun Wang Yue Zhao Enke Wang Zhilie Tang Dapeng Yu Kaihui Liu | 2022 | Nano Research2022，15，2： | 0 |
| 19 | Strong and Tough PAm/SA Hydrogel with Highly Strain Sensitivity显示文摘The hydrogel is a preferred material for flexible wearable sensors.In practical application,it should have high-efficiency mechanical toughness and self-healing performance.Besides,hydrogel requires good affinity and adhe-sion because of its contact with the skin.In this experiment,we made an ultra-tough hydrogel with excellent cell affinity and adhesion.We used sodium alginate(SA)and polyacrylamide(PAm)mixture as a flexible base fluid.Polydopamine reduce graphene oxide(prGO)was used as conductive nanofiller,and then PAm-prGO-SA semi-interpenetrating network hydrogel was formed through Am radical polymerization.The presence of prGO endows the hydrogels with excellent electrical conductivity.Simultaneously,some non-reduced GO forms non-covalent cross-links with PAm,SA,and Polydopamine(PDA)in the hydrogel network.The stress of PAm-prGO-SA hydrogel can reach 750 KPa,and the strain is 900%.The hydrogel,combined with its excellent electrical,mechanical properties,and biocompatibility,is expected to be applied in portable,remote,and real-time health monitoring systems. | Lingqin Zhang Qifeng Jiang Yiming Zhao Jie Yuan Xiaoying Zha Haojiang Xie Fankai Kong Xingliang Xiong | 2022 | Journal of Renewable Materials2022，10，2： | 0 |
