| 1 | Importance of bifurcation angle in bifurcation stenting显示文摘Bifurcation coronary lesions are relatively frequent in today's interventional cardiology practice,averaging between 10%-15% of all percutaneous coronary interventions(PCIs).1 Several problems inherent in the treatment of bifurcation lesions are periprocedural side branch(SB)compromise(composite of SB closure or appearance of significant ostial stenosis after main vessel(MV)stenting causing ischemia)frequently related to periprocedural myonecrosis,relatively higher restenosis rates especially in two-stent techniques,and higher rates of stent thrombosis in different time frames.1-4 The lead author and other investigators demonstrated that both periprocedural result and long-term results could be influenced by bifurcation angulations.The purpose of this study is to show why and how bifurcation angulations are important for bifurcation stenting. | Dobrin Vassilev Alexander Alexandrov Dan Le Katrina Nguyen James Nguyen Hung Phan Robert J.

| 2 | Self-propagating high-temperature synthesis of ZrO_2 incorporated Gd_2Ti_2O_7 pyrochlore显示文摘In this research, Zr-doped Gd_2Ti_2O_7 pyrochlores, with the composition of Gd_2(Ti_(1-x)Zr_x)_2O_7, were firstly synthesized by self-propagating high-temperature synthesis plus quick pressing(SHS/QP) using CuO as the oxidant and Ti as the reductant. To improve the radiation resistance of titanate–pyrochlore, up to 35 at% Zr was incorporated to substitute the Ti site of Gd_2Ti_2O_7 pyrochlore(Gd_2(Ti_(0.75)Zr_(0.35))_2O_7). XRD and SEM microstructural characterizations showed the formation of a composite ceramic with the major pyrochlore phase and the minor Cu phase. The generated temperature of samples decreased from 1702to 1011 ℃ with increasing Zr content. The effects of sintering temperature and pressure time on phase composition and microstructure were systematically studied. Besides, the influence of thermal transmission on the whole combustion process was also explored. The pyrochlore-based waste form possessed high bulk density of 6.25 g/cm^3 and Vickers hardness of 10.81 GPa. The MCC-1 leaching test showed the normalized elemental leaching rates(42d) of Cu, Gd, and Zr are 1.27×10^(-2), 1.33×10^(-3), and 8.44×10^(-7)g·m^(-2)·d^(-1), respectively. | Le PENG Kuibao ZHANG Zongsheng HE Dan YIN Jiali XUE Chen XU Haibin ZHANG | 2018 | Journal of Advanced Ceramics2018，7，1： | 5 |
| 3 | Solid-state reaction synthesis and chemical stability studies in Nd-doped zirconolite-rich ceramics显示文摘In this study, Nd-bearing zirconolite-rich ceramics were prepared by solid-state reaction process using CaF_2,ZrO_2, Ti,TiO_2, Fe_2 O_3 and Nd_2O_3 as the raw materials. Neodymium was used as trivalent actinide surrogate and designed to substitute the Ca and Zr sites of zirconolite with general stoichiometry of Ca_(1-x)Zr_(1-x)Nd_(2 x)Ti_2O_7(0≤x≤0.3). Density of Fe-Nd-O sample reaches a maximum value of 4.13 g/cm^2 after being sintered at 1325 ℃ for 42 h. Three major phases, namely zirconolite, perovskite and pseudobrookite, are observed in all these samples. The EDX result shows that Nd_2O_3 can be successfully incorporated into the lattice structure of the prepared zirconolite-rich minerals and replace the Ca sites of zirconolite and perovskite with Fe^(3+) as the charge-compensating ion. Furthermore, the thermal conductivities are all in the range of 1.51-1.67 W/(m·K). The normalized elemental leaching rates of Ca and Nd in the Fe-Nd-0.2 sample keep in low values of 6.20 × 10^(-2) and 4.86 x 10^(-4) g/(m^2·d) after 42 d. | Dan Yin Kuibao Zhang Le Peng Zongsheng He Yuan Liu Haibin Zhang Xirui Lu | 2018 | Journal of Rare Earths2018，36，5： | 5 |
| 4 | Six new monacolin analogs from red yeast rice显示文摘Six novel monacolin analogs, monacolins V_1–V_6(1–6), together with seven known ones(7–13), were isolated from the ethyl acetate extract of red yeast rice. Their structures and absolute configurations were determined by spectroscopic methods,especially 2D NMR(~1H-~1HCOSY, HSQC, HMBC, and NOESY/ROESY) and CD spectroscopic analyses as well as chemical derivation.Monacolins V_2(2) and V_3(3) represent the first examples of monacolins with 3-hydroxybutyrate substitute. The anti-inflammatory inhibitory activities against the lipopolysaccharide(LPS) induced NO production in BV-2 cells as well as antioxidant activities against rat liver microsomal lipid peroxidation were evaluated. | LIU Bing-Yu XU Fei BAI Jian YAN Dao-Jiang ZHANG Le ZHANG Dan HU You-Cai | 2019 | Chinese Journal of Natural Medicines2019，17，5： | 3 |
| 5 | Cross-Scale Synthesis of Organic High-k Semiconductors Based on Spiro-Gridized Nanopolymers显示文摘High dielectric constants in organic semiconductors have been identified as a central challenge for the improvement in not only piexoelectric,preolecric,and freeltric efcts but also photoclecric conversion eficiency in OPVs,carrier mobility in OFETS,and charge density in charge-trapping memories.Herein,we report an ultralong persistence length(≈41 nm)efet of spiro-fused organic nanopolymers on dielectric properties,together with excitonic and charge carrier behaviors.The state-of-the-art nanopolymers,namely,nanopolyspirogrids(NPSGs),are synthesized via the simple crossscale Friedel-Crafts polygridlization of AjB-type nanomonomers.The high dielectric constant(k=8.43)of NPSG is firstly achieved by locking spiro-polygridization efect that results in the enhancement of dipole polarization.When doping into a polystyrene-based dielectric layer,such a high-k feature of NPSG increases the feld-ffct carrier mobility from 0.20 to 0.90cm^(2)Vl s'in pentacene OFET devices.Meanwhile,amorphous NPSG film exhibits an ultralow energy disorder(<50 meV)for an exellent zero-field hole mobility of 3.94×10^(-1)cm^(2)V^(-1)s^(-1).surpassing most of the amorphousπconjugated polymers Onganic nanopolymers with high dielectric constants open a new way to break through the bottleneck of eficiency and multifunctionality in the blueprint of the fourth generation semiconductors. | Dongqing Lin Wenhua Zhang Hang Yin Haixia Hu Yang Li He Zhang Le Wang Xinmiao Xie Hongkai Hu Yongxia Yan Haifeng Ling Jin'an Liu Yue Qian Lei Tang Yongxia Wang Chaoyang Dong Linghai Xie Hao Zhang Shasha Wang Ying Wei Xuefeng Guo Dan Lu Wei Huang | 2022 | Research2022，，2： | 3 |

| 7 | Electrochemical exfoliation of two-dimensional layered black phosphorus and applications显示文摘With the discovery of graphene,black phosphorus(BP)has been rediscovered as a two-dimensional(2 D)layered material.Since its first preparation in 2014,2 D BP has elicited immense interest,and has exhibited excellent properties,such as distinct pleated structures in layers,adjustable direct bandgap,high carrier mobility,moderate on/off ratio,large specific surface area,and various interesting in-layer anisotropies.However,the realization of these excellent properties depends on the preparation of highquality 2 D BP sheets.Electrochemical exfoliation methods are typically performed under mild conditions,thus,these methods are convenient,controllable,and can produce high-quality 2 D BP sheets.This review summarizes research progress in BP sheets preparation through anodic,cathodic,and electrolyte exfoliation in recent years.Different exfoliating methods affect the quality of 2 D BP sheets.Moreover,possible exfoliating mechanisms and the potential applications of different exfoliating methods are summarized and discussed in detail.Lastly,the shortcomings of existing research on electrochemical exfoliation are presented,and suggestions and prospects for future research on the electrochemical exfoliation of 2 D BP are proposed. | Le Li Dan Zhang Jianping Deng Yuchun Gou Junfei Fang | 2020 | Journal of Energy Chemistry2020，29，10： | 2 |
| 8 | Regulating closed pore structure enables significantly improved sodium storage for hard carbon pyrolyzing at relatively low temperature显示文摘The closed pore has been considered as the key structure for Na ion storage in hard carbon.However,the traditional view is that closed pores can only be formed by the curling of graphite-like crystallites in the case of high temperature carbonization.Ingenious designing of closed pore structures at lower temperature is still blank.Herein,for the first time,engineering the wall thickness and number of closed pores in waste rosewood-derived hard carbon was successfully achieved at a low temperature of 1100℃ by removing the lignin and hemicellulose components in wood precursor.When applied as an anode material,the optimum sample exhibits a high capacity of 326 mAh/g at 20 mA/g and a remarkable rate capability of 230mAh/g at 5000 mA/g,significantly higher than those of the untreated sample(only 33 mAh/g at 5000 mA/g).The significantly improved Na storage performance should be attributed to abundant closed pores that provide sufficient spaces forNa storage and thin porewall structure that is beneficial to the diffusion of Na^(+)in the bulk phase.This work provides a new idea for the future application of biomass-based hard carbon for advanced Na ion batteries. | Siyu Zhou Zheng Tang Zhiyi Pan Yuancheng Huang Le Zhao Xi Zhang Dan Sun Yougen Tang Abdelghaffar S.Dhmees Haiyan Wang | 2022 | SusMat2022，2，3： | 2 |

| 10 | Study of the location of testing area in residual stress measurement by Moiré interferometry combined with hole-drilling method显示文摘This paper investigates the effect of the location of testing area in residual stress measurement by Moiréinterferometry combined with hole-drilling method.The selection of the location of the testing area is analyzed from theory and experiment.In the theoretical study,the factors which affect the surface released radial strainεr were analyzed on the basis of the formulae of the hole-drilling method,and the relations between those factors andεr were established.By combining Moiréinterferometry with the hole-drilling method,the residual stress of interference-fit specimen was measured to verify the theoretical analysis.According to the analysis results,the testing area for minimizing the error of strain measurement is determined.Moreover,if the orientation of the maximum principal stress is known,the value of strain will be measured with higher precision by the Moiréinterferometry method. | QIN Le XIE HuiMin ZHU RongHua WU Dan CHE ZhiGang ZOU ShiKun | 2014 | Science China(Physics,Mechanics & Astronomy)2014，57，4： | 2 |

| 12 | Surfactant-assisted fabrication of graphene frameworks endowing epoxy composites with superior thermal conductivity显示文摘With the rapid growth in electronic device performance,there has been an increasing demand for thermally conductive polymer composites to handle the thermal management issue,thus contributing to the great importance to develop the graphene framework,which is evaluated as the most promising reinforcements for enhancing the thermal conductivity of polymer.Vacuum filtration is a common method to fabricate graphene framework,whereas,it is available to prepare a framework with centimeter-scale thickness by filtrating the graphene-water dispersion,due to the fact of sample cracking caused by the mismatch of surface tension between graphene and water.In this work,a surfactantassisted strategy was proposed by adjusting the surface tension of the water close to that of graphene first,then performing a conventional filtration process,to fabricate graphene framework.As a result,a thick graphene framework(thickness:3 cm)was successfully prepared,and after embedding into epoxy,the framework endows the composite(13.6 wt%)with a high in-plane thermal conductivities of12.4 W/mK,which is equivalent to≈64 times higher than that of neat epoxy.Our method is simple and compatible with the conventional filtration process,suggesting great potential for the mass-production of graphene framework to meet the practical application requirements. | Fan Zhang Chen Ye Wen Dai Le Lv Qilong Yuan Kuan W.A.Chee Ke Yang Nan Jiang Cheng-Te Lin Zhaolin Zhan Dan Dai He Li | 2020 | Chinese Chemical Letters2020，31，1： | 2 |
