| 1 | Early Permian–Late Triassic Magmatism in the Tuotuohe Region of the Qinghai–Tibet Plateau: Constraints on the Tectonic evolution of the Western Segment of the Jinshajiang Suture显示文摘In this paper we present new zircon U–Pb ages, whole-rock major and trace element analyses, and zircon Hf isotopic data for magmatic rocks in the Tuotuohe region of the western segment of the Jinshajiang suture. Our aim is to constrain the Early Permian–Late Triassic tectonic evolution of the region. Zircons from the magmatic rocks of the Tuotuohe region are euhedral–subhedral in shape and display fine-scale oscillatory zoning as well as high Th/U ratios(0.4–4.6), indicating a magmatic origin. The zircon U–Pb ages obtained using LA–ICP–MS are 281 ± 1 Ma, 258 ± 1 Ma, 244 ± 1 Ma, and 216 ± 1 Ma, which indicate magmatism in the Early Permian–Late Triassic. A diorite from Bashihubei(BSHN) has SiO2 = 57.18–59.97 wt%, Al2O3 = 15.70–16.53 wt%, and total alkalis(Na2O + K2O) = 4.46–6.34 wt%, typical of calc-alkaline and metaluminous series. A gabbro from Bashibadaoban(BSBDB) belongs to the alkaline series, and is poor in SiO2(45.46–54.03 wt%) but rich in Al2O3(16.19–17.39 wt%) and total alkalis(Na2O + K2O = 5.48–6.26 wt%). The BSHN diorite and the BSBDB gabbro both display an enrichment of LREEs and LILEs and depletion of HFSEs, and they have no obvious Eu anomaly; they have relatively low MgO contents(2.54–4.93 wt%), Mg# values of 43 to 52, and low Cr and Ni contents(8.07–33.6 ppm and 4.41–14.2 ppm, respectively), indicating they differentiated from primitive mantle magmas. They have low Nb/U, Ta/U, and Ce/Pb ratios(1.3–9.6, 0.2–0.8, and 0.1–18.1, respectively), and their initial Hf isotopic ratios range from +9.6 to +16.9(BSHN diorite) and +6.5 to +12.6(BSBDB gabbro), suggesting their primary magmas were derived mainly from the partial melting of a mantle wedge that had been metasomatized by subduction fluids. Taking all the new data together, we conclude that the western and eastern segment of the Jinshajiang suture regions underwent identical processes of evolution in the Early Permian–Late Triassic: oceanic crust subduction before the Early Permian, continental collision during the Early–Middle Triassic, and post-collisional extension from the Late Triassic. | QIAN Ye SUN Fengyue LI Bile LI Shijin ZHAO Junwei | 2014 | Acta Geologica Sinica(English Edition)2014，88，2： | 12 |
| 2 | Influence of thermal inhibitor position and temperature on vortex-shedding-driven pressure oscillations显示文摘Vortex-acoustic coupling is one of the most important potential sources of combustion instability in solid rocket motors (SRMs). Based on the Von Karman Institute for Fluid Dynamics (VKI) experimental motor, the influence of the thermal inhibitor position and temperature on vortex-shedding-driven pressure oscillations is numerically studied via the large eddy simulation (LES) method. The simulation results demonstrate that vortex shedding is a periodic process and its accurate frequency can be numerically obtained. Acoustic modes could be easily excited by vortex shedding. The vortex shedding frequency and second acoustic frequency dominate the pressure oscillation characteristics in the chamber. Thermal inhibitor position and gas temperature have little effect on vortex shedding frequency, but have great impact on pressure oscillation amplitude. Pressure amplitude is much higher when the thermal inhibitor locates at the acoustic velocity anti-nodes. The farther the thermal inhibitor is to the nozzle head, the more vortex energy would be dissipated by the turbulence. Therefore, the vortex shedding amplitude at the second acoustic velocity antinode near 3/4L (L is chamber length) is larger than those of others. Besides, the natural acoustic frequencies increase with the gas temperature. As the vortex shedding frequency departs from the natural acoustic frequency, the vortex-acoustic feedback loop is decoupled. Consequently, both the vortex shedding and acoustic amplitudes decrease rapidly. | Su Wanxing Li Shipeng Zhang Qiao Li Junwei Ye Qingqing Wang Ningfei | 2013 | Chinese Journal of Aeronautics2013，26，3： | 4 |
| 3 | Digital holographic microscopy with phase-shift-free structured illumination显示文摘When structured illumination is used in digital holographic microscopy(DHM),each direction of the illumination fringe is required to be shifted at least three times to perform the phase-shifting reconstruction.In this paper,we propose a scheme for spatial resolution enhancement of DHM by using the structured illumination but without phase shifting.The structured illuminations of different directions,which are generated by a spatial light modulator,illuminate the sample sequentially in the object plane.The formed object waves interfere with a reference wave in an off-axis configuration,and a CCD camera records the generated hologram.After the object waves are reconstructed numerically,a synthetic aperture is performed by an iterative algorithm to enhance the spatial resolution.The resolution improvement of the proposed method is proved and demonstrated by both simulation and experiment. | Juanjuan Zheng Peng Gao Baoli Yao Tong Ye Ming Lei Junwei Min Dan Dan Yanlong Yang Shaohui Yan | 2014 | Photonics Research2014，2，3： | 2 |
| 4 | Recent advances in modification strategies of silicon-based lithiumion batteries显示文摘As potential alternatives to graphite,silicon(Si)and silicon oxides(SiO_(x))received a lot of attention as anode materials for lithiumion batteries owing to their relatively low working potentials,high theoretical specific capacities,and abundant resources.However,the commercialization of Si-based anodes is greatly hindered by their massive volume expansion,low conductivity,unstable solid electrolyte interface(SEI),and low initial Coulombic efficiency(ICE).Continuous endeavors have been devoted to overcoming these challenges to achieve practical usage.This review is centered on the major challenges and latest developments in the modification strategies of Si-based anodes,including structure optimization,surface/interface regulation,novel binders,and innovative design of electrolyte.Finally,outlooks and perspectives of Si-based anodes for future development are presented. | Wenlei Wang Yu Wang Lixuan Yuan Chaolin You Junwei Wu Lili Liu Jilei Ye Yunling Wu Lijun Fu | 2023 | Nano Research2023，16，3： | 1 |

| 10 | Micelles-template induced organic nanocrystals based on iodo…nitro interactions显示文摘The nanocrystals based on a polar organic compound INBP (4-iodo-4′-nitrobiphenyl) have been fabricated by reprecipitation approach. For the formation of INBP based nanocrystals, the intermolecular iodo…nitro interaction is the dominant driving force and the micelles formed by the surfactant CTAB (cetyltrimethylammonium bromide) molecules are the efficient templates for controlling morphologies of nanocrystals. The field emission scanning electro microscope (FESEM) images demonstrated that prism-like and needle-like nanocrystals of INBP were formed in pure water and micell containing aqueous solution, respectively. XRD pattern and UV/vis absorption spectra were employed to characterize the nanocrystals. | WANG Jia ZHANG ZuoLun YE JunWei ZHANG JingYingt WANG Yuet | 2007 | Chinese Science Bulletin2007，52，10： | 1 |

| 13 | Over 16% efficiency all-polymer solar cells by sequential deposition显示文摘All-polymer solar cells(all-PSCs) have received extensive attention due to their excellent mechanical robustness and performance stability. However, the power conversion efficiency(PCE) of all-PSCs still lags behind those of organic solar cells(OSCs)based on non-fullerene small molecule acceptors. Herein, we report highly efficient all-PSCs via sequential deposition(SD) with donor and acceptor layers coated sequentially to optimize the film microstructure. Compared with the bulk heterojunction(BHJ)all-PSCs, an optimized morphology with vertical component distribution was achieved for the SD-processed all-PSCs due to the synergistic effect of swelling of polymer films and using additive. Such strategy involves using chlorobenzene as the first layer processing-solvent for polymer donor, chloroform as the second processing-solvent for polymer acceptor with trace 1-chloronaphthalene, efficiently promoting exciton dissociation and charge extraction and reducing trap-assisted recombination.Consequently, over 16% all-PSCs fabricated via SD method was realized for the first time, which is much higher than that(15.2%) of its BHJ counterpart and also among the highest PCEs in all-PSCs. We have further demonstrated the generality of this approach in various all-polymer systems. This work indicates that the SD method can yield excellent all-PSCs and provides a facile approach to fabricating high-performance all-PSCs. | Bangbang Li Xuanyu Zhang Ziang Wu Jie Yang Bin Liu Qiaogan Liao Junwei Wang Kui Feng Rui Chen Han Young Woo Fei Ye Li Niu Xugang Guo Huiliang Sun | 2022 | Science China Chemistry2022，65，6： | 1 |

| 15 | Simultaneous Optimization of Efficiency,Stretchability,and Stability in All-Polymer Solar Cells via Aggregation Control显示文摘With the emergence of Y-series small molecule acceptors,polymerizing the small molecule acceptors with aromatic linker units has attracted significant research attention,which has greatly advanced the photovoltaic performance of all-polymer solar cells.Despite the rapid increase in efficiency,the unique characteristics(e.g.,mechanical stretchability and flexibility)of all-polymer systems were still not thoroughly explored.In this work,we demonstrate an effective approach to simultaneously improve device performance,stability,and mechanical robustness of all-polymer solar cells by properly suppressing the aggregation and crystallization behaviors of polymerized Y-series acceptors.Strikingly,when introducing 50 wt%PYF-IT(a fluorinated version of PY-IT)into the well-known PM6:PY-IT system,the all-polymer devices delivered an impressive photovoltaic efficiency of 16.6%,significantly higher than that of the control binary cell(15.0%).Compared with the two binary systems,the optimal ternary blend exhibits more efficient charge separation and balanced charge transport accompanying with less recombination.Moreover,a high-performance 1.0 cm^(2)large-area device of 15%efficiency was demonstrated for the optimized ternary all-polymer blend,which offered a desirable PCE of 14.5%on flexible substrates and improved mechanical flexibility after bending 1000 cycles.Notably,these are among the best results for 1.0 cm^(2)all-polymer OPVs thus far.This work also heralds a bright future of all-polymer systems for flexible wearable energy-harvesting applications. | Kaihu Xian Kangkang Zhou Mingfei Li Junwei Liu Yaowen Zhang Tao Zhang Yong Cui Wenchao Zhao Chunming Yang Jianhui Hou Yanhou Geng Long Ye | 2023 | Chinese Journal of Chemistry2023，41，2： | 1 |

| 17 | Refining acceptor aggregation in nonfullerene organic solar cells to achieve high efficiency and superior thermal stability显示文摘With the rapid increase in photoelectric conversion efficiency of organic photovoltaics(OPVs),prolonging the operational lifetime of devices becomes one of the critical prerequisites for commercial applications.Guided by the theoretical calculations of molecular stacking and miscibility,we proposed an effective approach to simultaneously improve device performance and thermal stability of high-efficiency OPVs by refining the aggregation of Y-series acceptors.The key to this approach is deliberately designing an asymmetric Y-series acceptor,named Y6-CNO,which acts as a third component regulator to finely tune the degree of acceptor aggregation and crystallization in the benchmark PM6:Y6-BO system.Strikingly,a champion photovoltaic efficiency of 18.0%was achieved by introducing 15 wt%Y6-CNO into the PM6:Y6-BO system,significantly higher than the control binary cell(16.7%).Moreover,annealing at 100°C for over 1,200 h does not markedly affect the photovoltaic performance of the optimal ternary devices,maintaining above 95%of the initial performance and exhibiting an exceptionally high T_(80)lifetime of 9,000 h under continuous thermal annealing.By contrast,binary devices suffer from excessive crystallization of acceptors with long-term annealing.Additionally,mixing thermodynamics combined with morphological characterizations were employed to elucidate the microstructure-thermal stability relationships.The ternary OPVs consisting of symmetric and asymmetric homologous acceptors form better charge transport channels and can effectively suppress excessive aggregation of acceptors under long-term annealing.This work demonstrates the effectiveness of refining acceptor aggregation via molecular design for highly efficient and stable nonfullerene-based OPVs. | Kaihu Xian Shengnan Zhang Ye Xu Junwei Liu Kangkang Zhou Zhongxiang Peng Mingfei Li Wenchao Zhao Yu Chen Zhuping Fei Jianhui Hou Yanhou Geng Long Ye | 2023 | Science China Chemistry2023，66，1： | 0 |

| 19 | Gas diffusion in catalyst layer of flow cell for CO_(2) electroreduction toward C_(2+) products显示文摘The use of gas diffusion electrode(GDE)based flow cell can realize industrial-scale CO_(2) reduction reactions(CO_(2)RRs).Controlling local CO_(2) and CO intermediate diffusion plays a key role in CO_(2)RR toward multi-carbon(C_(2+))products.In this work,local CO_(2) and CO intermediate diffusion through the catalyst layer(CL)was investigated for improving CO_(2)RR toward C_(2+)products.The gas permeability tests and finite element simulation results indicated CL can balance the CO_(2) gas diffusion and residence time of the CO intermediate,leading to a sufficient CO concentration with a suitable CO_(2)/H_(2)O supply for high C_(2+)products.As a result,an excellent selectivity of C_(2+)products~79%at a high current density of 400 mA·cm^(-2) could be obtained on the optimal 500 nm Cu CL(Cu500).This work provides a new insight into the optimization of CO_(2)/H_(2)O supply and local CO concentration by controlling CL for C_(2+)products in CO_(2)RR flow cell. | Xiqing Wang Qin Chen Yajiao Zhou Yao Tan Ye Wang Hongmei Li Yu Chen Mahmoud Sayed Ramadan A.Geioushy Nageh K.Allam Junwei Fu Yifei Sun Min Liu | 2024 | Nano Research2024，17，3： | 0 |
