| 1 | Synthesis and properties of ultrahigh molecular weight polyethylene/WS_2 nanoparticle fiber for bullet-proof materials显示文摘Ultrahigh molecular weight polyethylene (UHMWPE)/WS2 nanoparticle fibers were prepared by adding WS2 nanoparticles treated by coupling agent in the precursor solution of UHMWPE. The influence of WS2 nanoparticles on the microstructure and properties of UHMWPE fibers was characterized by SEM, TGA, mechanical property measurement and bullet-shock test. The results showed that WS2 nanoparticles can be uniformly dispersed in the UHMWPE fiber. After incorporating of WS2 nanoparticles, UHMWPE fibers became stiffer and tougher than the pristine ones. Particularly, the modulus of the fiber increased from 1203 to 1326cN/dtex. Furthermore, UHMWPE/WSfibers showed an improved thermal stability. | MA Tian ZHANG Tao GAO PengGang ZHANG JianChun | 2013 | Chinese Science Bulletin2013，58，8： | 6 |

| 3 | Effect of Tm-Er concentration ratio on the photoluminescence of Er-Tm:Al_2O_3 thin films fabricated by pulsed laser deposition显示文摘Er-Tm codoped amorphous aluminum oxide(a-Al2O3)thin films have been prepared by an alternative pulsed laser deposition.The phase structure and the surface of the deposited thin films were characterized by the X-ray diraction(XRD)and scanning electron microscopy(SEM),respectively.Eective photoluminescence(PL)in the region of 350-900 nm was observed when pumped at 325 nm,and the PL performance has been improved by modifying the Tm3 +concentration.With the increasing of[Tm]/[Er]concentra-tion ratio,the intensity of emission of 382 nm and 500 nm bands was improved eectively while that of 765 nm band increased smoothly.Our results suggest that the resonant energy transfer and cross relaxation between Tm3 +and Er 3+play an important role in the evolution of the luminescent response. | Bo Zhou Zhisong Xiao Anping Huan Lu Yan Fang Zhu Jinliang Wang Penggang Yin Hao Wang | 2008 | Progress in Natural Science:Materials International2008，18，6： | 2 |

| 10 | Fabrication of carbonized spent coffee grounds/graphene nanoplates/cyanate ester composites for superior and highly absorbed electromagnetic interference shielding performance显示文摘The conductive polymer composites(CPCs) with highly efficient electromagnetic interference(EMI)shielding effectiveness(SE) are always accompanied with excessive reflectivity, which would cause serious secondary EMI pollution. In this regard, the significant reduction of EMI reflection of CPCs to alleviate secondary pollution is deemed to be very important. Herein, a promising cyanate ester(CE) based composite was successfully fabricated by compounding carbonized spent coffee grounds(C-SCG) and graphene nanosheets(GNSs) via a facile solution blending followed by a hot-pressing method. Benefiting from the porous structure of C-SCG and the layered structure of GNSs, a three-dimensional(3 D)multi-interface conductive network in the CE was easily constructed. The EMI SE of the resultant 9 wt%C-SCG/CE composite(C9) is 15.38 d B and dramatically enhanced to 31.09 d B with the presence of 3 wt% GNSs. The remarkable enhancement is mainly attributed to the formation of the efficient conductive pathways as well as the well-dispersion of the incorporated fillers. Meanwhile, the absorption-dominated shielding mechanism in the prepared composites gets benefit from the synergistic effect of porous C-SCG and lamellar GNSs, which effectively captures and attenuates electromagnetic waves. These encouraging findings extend the practical applications of porous biocarbon materials in EMI shielding field. | Zhengzheng Guo Penggang Ren Zengping Zhang Zhong Dai Zhenxia Lu Yanling Jin Fang Ren | 2022 | Journal of Materials Science & Technology2022，，7： | 1 |

| 17 | Role of blood pressure on stroke-related mortality:a 45-year follow-up study in China显示文摘Background:Hypertension is associated with stroke-related mortality.However,the long-term association of blood pressure(BP)and the risk of stroke-related mortality and the influence path of BP on stroke-related death remain unknown.The current study aimed to estimate the long-term causal associations between BP and stroke-related mortality and the potential mediating and moderated mediating model of the associations.Methods:This is a 45-year follow-up cohort study and a total of 1696 subjects were enrolled in 1976 and 1081 participants died by the latest follow-up in 2020.COX proportional hazard model was used to explore the associations of stroke-related death with baseline systolic blood pressure(SBP)/diastolic blood pressure(DBP)categories and BP changes from 1976 to 1994.The mediating and moderated mediating effects were performed to detect the possible influencing path from BP to stroke-related deaths.E value was calculated in the sensitivity analysis.Results:Among 1696 participants,the average age was 44.38±6.10 years,and 1124 were men(66.3%).After a 45-year follow-up,a total of 201(11.9%)stroke-related deaths occurred.After the adjustment,the COX proportional hazard model showed that among the participants with SBP≥160 mmHg or DBP≥100 mmHg in 1976,the risk of stroke-related death increased by 217.5%(hazard ratio[HR]=3.175,95%confidence interval[CI]:2.297-4.388),and the adjusted HRs were higher in male participants.Among the participants with hypertension in 1976 and 1994,the risk of stroke-related death increased by 110.4%(HR=2.104,95%CI:1.632-2.713),and the adjusted HRs of the BP changes were higher in male participants.Body mass index(BMI)significantly mediated the association of SBP and stroke-related deaths and this mediating effect was moderated by gender.Conclusions:In a 45-year follow-up,high BP and persistent hypertension are associated with stroke-related death,and these associations were even more pronounced in male participants.The paths of association are mediated by BMI and moderated by gender. | Shengshu Wang Shanshan Yang Wangping Jia Ke Han Yang Song Jing Zeng Wenzhe Cao Shaohua Liu Shimin Chen Zhiqiang Li Xuehang Li Penggang Tai Fuyin Kou Yao He Miao Liu | 2022 | Chinese Medical Journal2022，，4： | 1 |
