| 1 | Microstructure and thermal conductivity of copper matrix composites reinforced with mixtures of diamond and SiC particles显示文摘The thermal conductivity of diamond hybrid SiC/Cu,diamond/Cu and SiC/Cu composite were calculated by using the extended differential effective medium (DEM) theoretical model in this paper.The effects of the particle volume fraction,the particle size and the volume ratio of the diamond particles to the total particles on the thermal conductivity of the composite were studied.The DEM theoretical calculation results show that,for the diamond hybrid SiC/Cu composite,when the particle volume fraction is above 46% and the volume ratio of the diamond particles to the SiC particles is above 13:12,the thermal conductivity of the composite can reach 500 W·m-1·K-1.The thermal conduc-tivity of the composite has little change when the particle size is above 200μm.The experimental results show that Ti can improve the wettability of the SiC and Cu.The thermal conductivity of the diamond hybrid SiCTi/Cu is almost two times better than that of the diamond hybrid SiC/Cu.It is feasible to predict the thermal conductivity of the composite by DEM theoretical model. | Han, Yuanyuan Guo, Hong Yin, Fazhang Zhang, Ximin Chu, Ke Fan, Yeming | 2012 | Rare Metals2012，31，1： | 14 |
| 2 | Interfacial microstructure and properties of diamond/Cu-xCr composites for electronic packaging applications显示文摘Diamond/Cu-xCr composites were fabricated by pressure infiltration process.The thermal conductivities of diamond/Cu-xCr(x = 0.1,0.5,0.8) composites were above 650 W/mK,higher than that of diamond/Cu composites.The tensile strengths ranged from 186 to 225 MPa,and the bonding strengths ranged from 400 to 525 MPa.Influences of Cr element on the thermo-physical properties and interface structures were analyzed.The intermediate layer was confirmed as Cr3C2 and the amount of Cr3C2 increased with the increase of Cr concentration in Cu-xCr alloys.When the Cr concentration was up to 0.5 wt.%,the content of the Cr3C2 layer was constant.As the thickness of the Cr3C2 layer became larger,the composites showed a lower thermal conductivity but higher mechanical properties.The coefficients of thermal expansion(CTE) of diamond/Cu-xCr(x = 0.1,0.5,0.8) composites were in good agreement with the predictions of the Kerner' model. | ZHANG Ximin GUO Hong YIN Fazhang FAN Yeming ZHANG Yongzhong | 2011 | Rare Metals2011，30，1： | 12 |
| 3 | Pressure infiltrated Cu/diamond composites for LED applications显示文摘Diamond reinforced copper (Cu/diamond) composites were prepared by a pressure infiltration technique.The composites show a super high conductivity of 713 W m-1 K-1 in combination with an extremely low coefficient of thermal expansion (CTE) of 7.72 × 10-6 K-1 (25-100 ℃),which are achieved by modifying the copper matrix with adding 0.3 wt.% of boron to get a good thermal contact between the matrix and the diamond particles.By adopting a series of postmachining techniques the composites were made into near-net-shape parts,and an electroless silver coating was also successfully plated on the composites.Finally,their potential applications in the thermal management of light emitting diodes (LED) were illustrated via prototype examples. | FAN Yeming GUO Hong XU Jun CHU Ke ZHU Xuexin JIA Chengchang YIN Fazhang | 2011 | Rare Metals2011，30，2： | 4 |
| 4 | Regulation of the order-disorder phase transition in a Cs_(2)NaFeCl_(6) double perovskite towards reversible thermochromic application显示文摘Multifunctional lead-free double perovskites demonstrate remarkable potential towards applications in various fields.Herein,an environmentally-friendly,low-cost,high-throughput Cs_(2)NaFeCl_(6) single crystal with exceedingly high thermal stability is designed and grown.It obtains a cubic lattice system in the temperature range of 80-500 K,accompanied by a completely reversible chromatic variation ranging from yellow to black.Importantly,the intriguing thermochromism is proved to own extremely high reproducibility(over 1000 cycles)without a hysteretic effect,originating from its structural flexibility that including(i)the noteworthy distortion/deformation of[NaCl_(6)]5−and[FeCl_(6)]3−octahedra;(ii)order-disorder arrangement transition of[NaCl_(6)]5−and[FeCl6]3−octahedra as the function of temperature.This study paves the way towards a new class of smart windows and camouflage coatings with an unprecedented colour range based on a Cs_(2)NaFeCl_(6) perovskite. | Wenzhe Li Naveed Ur Rahman Yeming Xian Hang Yin Yunkai Bao Yi Long Songyang Yuan Yangyi Zhang Yaxuan Yuan Jiandong Fan | 2021 | Journal of Semiconductors2021，42，7： | 2 |
| 5 | Thermal conductivity of diamond/copper composites with a bimodal distribution of diamond particle sizes prepared by pressure infiltration method显示文摘The thermal conductivity of diamond/copper composites with bimodal particle sizes was studied.The composites were prepared through pressure infiltration of liquid copper into diamond preforms with a mixture of 40 and 100 μm-size diamonds.The permeability of the preforms with different coarse-to-fine volume ratios of diamonds was investigated.The thermal conductivity of the diamond/copper composites with bimodal size distribution was compared to the theoretical value derived from an analytical model developed by Chu.It is predicted that the diamond/copper composites could reach a higher thermal conductivity and their surface roughness could be improved by applying bimodal diamond particle sizes. | CHEN Chao GUO Hong CHU Ke YIN Fazhang ZHANG Ximing HAN Yuanyuan FAN Yeming | 2011 | Rare Metals2011，30，4： | 2 |
| 6 | Use of angiotensin-converting enzyme inhibitors and angiotensin Ⅱ receptor blockers in context of COVID-19 outbreak:a retrospective analysis显示文摘The possible effects of angiotensin-converting enzyme inhibitors(ACEIs)or angiotensin Ⅱ receptor blockers(ARBs)on COVID-19 disease severity have generated considerable debate.We performed a single-center,retrospective analysis of hospitalized adult COVID-19 patients in Wuhan,China,who had definite clinical outcome(dead or discharged)by February 15,2020.Patients on anti-hypertensive treatment with or without ACEI/ARB were compared on their clinical characteristics and outcomes.The medical records from 702 patients were screened.Among the 101 patients with a history of hypertension and taking at least one anti-hypertensive medication,40 patients were receiving ACEI/ARB as part of their regimen,and 61 patients were on antihypertensive medication other than ACEI/ARB.We observed no statistically significant differences in percentages of in-hospital mortality(28%vs.34%,P=0.46),ICU admission(20%vs.28%,P=0.37)or invasive mechanical ventilation(18%vs.26%,P=0.31)between patients with or without ACEI/ARB treatment.Further multivariable adjustment of age and gender did not provide evidence for a significant association between ACEI/ARB treatment and severe COVID-19 outcomes.Our findings confirm the lack of an association between chronic receipt of reninangiotensin system antagonists and severe outcomes of COVID-19.Patients should continue previous antihypertensive therapy until further evidence is available. | Jiuyang Xu Chaolin Huang Guohui Fan Zhibo Liu Lianhan Shang Fei Zhou Yeming Wang Jiapei Yu Luning Yang Ke Xie Zhisheng Huang Lixue Huang Xiaoying Gu Hui Li Yi Zhang Yimin Wang Frederick G.Hayden Peter W.Horby Bin Cao Chen Wang | 2020 | Frontiers of Medicine2020，14，5： | 2 |

| 10 | Cerebral ischemic injury after transcatheter aortic valve replacement in patients with pure aortic regurgitation显示文摘Considering the surgical risk stratification for patients with severe calcific aortic stenosis(AS),transcatheter aortic valve replacement(TAVR)is a reliable alternative to surgical aortic valve replacement(SAVR)(Fan et al.,2020,2021;Lee et al.,2021).Despite the favorable clinical benefits of TAVR,stroke remains a dreaded perioperative complication(Auffret et al.,2016;Kapadia et al.,2016;Kleiman et al.,2016;Huded et al.,2019).Ischemic overt stroke,identified in 1.4%to 4.3%of patients in TAVR clinical practice,has been associated with prolonged disability and increased mortality(Auffret et al.,2016;Kapadia et al.,2016;Levi et al.,2022).The prevalence of hyperintensity cerebral ischemic lesions detected by diffusion-weighted magnetic resonance imaging(DW-MRI)was reported to be about 80%,which is associated with impaired neurocognitive function and vascular dementia(Vermeer et al.,2003;Barber et al.,2008;Kahlert et al.,2010). | Xianbao LIU Hanyi DAI Jiaqi FAN Dao ZHOU Gangjie ZHU Abuduwufuer YIDILISI Jun CHEN Yeming XU Lihan WANG Jian'an WANG | 2023 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2023，24，6： | 0 |
| 11 | Impact of corticosteroids on initiation and half-year durability of humoral response in COVID-19 survivors显示文摘Background:The impact of corticosteroids on humoral responses in coronavirus disease 2019(COVID-19)sur-vivors during the acute phase and subsequent 6-month period remains unknown.This study aimed to determine how the use of corticosteroids influences the initiation and duration of humoral responses in COVID-19 survivors 6 months after infection onset.Methods:We used kinetic antibody data from the lopinavir-ritonavir trial conducted at Jin Yin-Tan Hospital in January 2020,which involved adults hospitalized with severe COVID-19(LOTUS,ChiCTR2000029308).Anti-body samples were collected from 192 patients during hospitalization,and kinetic antibodies were monitored at all available time points after recruitment.Additionally,plasma samples were collected from 101 COVID-19 survivors for comprehensive humoral immune measurement at the half-year follow-up visit.The main focus was comparing the humoral responses between patients treated with systemic corticosteroid therapy and the non-corticosteroid group.Results:From illness onset to day 30,the median antibody titre areas under the receiver operating characteristic curve(AUCs)of nucleoprotein(N),spike protein(S),and receptor-binding domain(RBD)immunoglobulin G(IgG)were significantly lower in the corticosteroids group.The AUCs of N-,S-,and RBD-IgM as well as neutralizing antibodies(NAbs)were numerically lower in the corticosteroids group compared with the non-corticosteroid group.However,peak titres of N,S,RBD-IgM and-IgG and NAbs were not influenced by corticosteroids.During 6-month follow-up,we observed a delayed decline for most binding antibodies,except N-IgM(��−0.05,95%CI[−0.10,0.00])in the corticosteroids group,though not reaching statistical significance.No significant difference was observed for NAbs.However,for the half-year seropositive rate,corticosteroids significantly accelerated the decay of IgA and IgM but made no difference to N-,S-,and RBD-IgG or NAbs.Additionally,corticosteroids group showed a trend towards delayed viral clearance compared with the non-corticosteroid group,but the results were not statistically significant(adjusted hazard ratio 0.71,95%CI 0.50-1.00;P=0.0508).Conclusion:Our findings suggested that corticosteroid therapy was associated with impaired initiation of the antibody response but this did not compromise the peak titres of binding and neutralizing antibodies.Throughout the decay phase,from the acute phase to the half-year follow-up visit,short-term and low-dose corticosteroids did not significantly affect humoral responses,except for accelerating the waning of short-lived antibodies. | Yeming Wang Li Guo Guohui Fan Yang Han Qiao Zhang Lili Ren Hui Zhang Geng Wang Xueyang Zhang Tingxuan Huang Weiyang Wang Lan Chen Lixue Huang Xiaoying Gu Xinming Wang Jingchuan Zhong Ying Wang Hui Li Jiapei Yu Zhibo Liu Chaolin Huang Bin Cao Jianwei Wang | 2024 | Chinese Medical Journal Pulmonary and Critical Care Medicine2024，2，1： | 0 |
| 12 | New form of geodetic coordinate system taking two length quantity as coordinate parameters显示文摘A new form of geodetic coordinate system based on geodesic coordinates instead of geodetic longitude and latitude was proposed.The vertical and horizontal geodesic coordinates measured with length were defined as coordinate parameters,but the two families of coordinate curves were still meridians and parallel circles.The first fundamental form on the ellipsoidal surface and its three coefficients were deduced by the geodesic coordinate.The formula for the latitudinal scale factor of length for geodetic parallel lines was derived,by which the obtained result conformed to that standard value calculated from geodetic latitude,and it is applicable in the range of 400 km from north to south.Therefore,it lays the foundation for establishing the differential equation and differential relationship based on this type of coordinate parameters;and consequently,it is convenient and accurate enough to operate on the ellipsoidal surface in this new form of geodetic coordinate system. | Yimin SHI Ziyang ZHU Yeming FAN | 2009 | Frontiers of Structural and Civil Engineering2009，3，1： | 0 |
| 13 | 降低可退货运输物品损失率的最优决策显示文摘可回收运输物品(RTI)因其在减少包装垃圾和提高供应链可持续性方面的优势而被广泛使用。然而,RTI的损失将导致产品流与RTI 供应不匹配,从而影响运营的连续性。本文研究了一个由单个制造商和单个零售商组成的RTI供应链,假设零售商可以通过投资于员工培训来减少RTI的损失。我们首先开发一个库存模型来最小化系统的总成本。然后分析了RTI闭环供应链的最优决策问题。我们比较了零售商投资于减少RTI损失和不投资于RTI损失的情况。结果表明,零售商投资减少RTI损失将提高供应链效率,降低系统总成本。然而,零售商只有在成本下降时才会投资。因此,我们认为侧付款是一种有效的激励,以刺激零售商的投资。并建立了考虑投资成本分担的非对称纳什议价模型来协调RTI供应链。我们比较了制造商和零售商的总最优成本。结果表明,该系统能够实现协调,降低了制造商和零售商的最优总成本。 | Xiangxiang Fan Yeming Gong Xianhao Xu Bipan Zou | 2019 | 绿色包装2019，0，3： | 0 |
