| 1 | 新型镍基高温合金在模拟燃煤锅炉环境中的腐蚀显示文摘在人工合成的煤灰/烟气环境中研究了一种新型镍基高温合金550℃和700℃的腐蚀行为和腐蚀机理.结果表明,合金在550℃发生了不均匀的点蚀,表面形成了一层很薄的Cr_2O_3膜,腐蚀按照硫化机制发展.合金在700℃腐蚀时,初期发生了氧化和硫化腐蚀,表面生成了保护性的氧化膜,并有内硫化物析出.由于合金表面生成CoO并在表面形成熔融态硫酸盐而逐渐进入加速腐蚀阶段,使合金遭受严重的低温热腐蚀.腐蚀产物外层为疏松的混合尖晶石化合物,内层为致密的氧化物层,在腐蚀层、腐蚀层与基体界面和Cr元素贫化区内分布着硫化物.合金耐腐蚀性能的迅速退化是合金表面Co及其氧化物在混合熔盐中的溶解所致. | 赵双群 谢锡善 Gaylord D.Smith | 2004 | 金属学报2004,40,6: | 27 |
| 2 | Extracellular matrix synthesis in vascular disease:hypertension,and atherosclerosis显示文摘Extracellular matrix(ECM) within the vascular network provides both a structural and regulatory role.The ECM is a dynamic composite of multiple proteins that form structures connecting cells within the network.Blood vessels are distended by blood pressure and,therefore,require ECM components with elasticity yet with enough tensile strength to resist rupture.The ECM is involved in conducting mechanical signals to cells.Most importantly,ECM regulates cellular function through chemical signaling by controlling activation and bioavailability of the growth factors.Cells respond to ECM by remodeling their microenvironment which becomes dysregulated in vascular diseases such hypertension,restenosis and atherosclerosis.This review examines the cellular and ECM components of vessels,with specific emphasis on the regulation of collagen type I and implications in vascular disease. | Markella Ponticos Barbara D.Smith | 2014 | The Journal of Biomedical Research2014,28,1: | 12 |

| 5 | Renal functional outcomes are not adversely affected by selective angioembolization following percutaneous nephrolithotomy显示文摘Objective:Selective angioembolization(SAE)effectively diagnoses and treats iatrogenic vascular complications following percutaneous nephrolithotomy(PCNL).Methods:We retrospectively reviewed 1329 consecutive PCNLs and identified patients who underwent SAE following PCNL with at least 12-month follow-up.Estimated glomerular filtration rate(eGFR)was calculated for all patients preoperatively,postoperatively and at last followup.A 1:2 matched cohort analysis was performed.Results:Twenty-three patients underwent SAE and matched to 46 controls.There was no statistically significant difference in preoperative,postoperative,and follow-up eGFR when comparing patients who underwent SAE and those with an uneventful course.Conclusion:Long-term eGFR is comparable in patients who undergo uncomplicated PCNL and those requiring SAE. | Ricardo Palmerola Vinay Patel Christopher Hartman Chris Sung David Hoenig Arthur D.Smith Zeph Okeke | 2017 | Asian Journal of Urology2017,4,1: | 6 |
| 6 | 高强耐蚀Ni-Co-Cr高温合金的组织稳定性显示文摘利用SEM,TEM及X射线衍射分析技术观察了高强耐蚀Ni-Co-Cr高温合金不同温度(704,750,849℃)长期时效1000 h及700℃长期时效至5008 h过程中的组织演变过程,结果表明,700℃即使长期时效5008 h,γ'相粗化缓慢, 而且没有发现TCP相(如σ相)的析出,当温度升高到750℃,γ'相迅速长大,晶界上碳化物析出增多,并析出片状的η相,导致合金冲击性能下降,温度达到849℃时,析出大量的η相,甚至形成魏氏组织形貌,由此可见,该合金在700℃时具有较好的组织稳定性。 | 刘仲青 董建新 张麦仓 赵双群 谢锡善 Gaylord D.Smith | 2002 | 金属学报2002,38,5: | 6 |
| 7 | The genetic framework for development of nephrolithiasis显示文摘Over 1%-15% of the population worldwide is affected by nephrolithiasis,which remains the most common and costly disease that urologists manage today.Identification of atrisk individuals remains a theoretical and technological challenge.The search for monogenic causes of stone disease has been largely unfruitful and a technological challenge;however,several candidate genes have been implicated in the development of nephrolithiasis.In this review,we will review current data on the genetic inheritance of stone disease,as well as investigate the evolving role of genetic analysis and counseling in the management of nephrolithiasis. | Vinaya Vasudevan Patrick Samson Arthur D.Smith Zeph Okeke | 2017 | Asian Journal of Urology2017,4,1: | 5 |

| 10 | Manufacture and characterization of graphene membranes with suspended silicon proof masses for MEMS and NEMS applications显示文摘Graphene’s unparalleled strength,chemical stability,ultimate surface-to-volume ratio and excellent electronic properties make it an ideal candidate as a material for membranes in micro-and nanoelectromechanical systems(MEMS and NEMS).However,the integration of graphene into MEMS or NEMS devices and suspended structures such as proof masses on graphene membranes raises several technological challenges,including collapse and rupture of the graphene.We have developed a robust route for realizing membranes made of double-layer CVD graphene and suspending large silicon proof masses on membranes with high yields.We have demonstrated the manufacture of square graphene membranes with side lengths from 7µm to 110µm,and suspended proof masses consisting of solid silicon cubes that are from 5µm×5µm×16.4µm to 100µm×100µm×16.4µm in size.Our approach is compatible with wafer-scale MEMS and semiconductor manufacturing technologies,and the manufacturing yields of the graphene membranes with suspended proof masses were>90%,with>70%of the graphene membranes having>90%graphene area without visible defects.The measured resonance frequencies of the realized structures ranged from tens to hundreds of kHz,with quality factors ranging from 63 to 148.The graphene membranes with suspended proof masses were extremely robust,and were able to withstand indentation forces from an atomic force microscope(AFM)tip of up to~7000nN.The proposed approach for the reliable and large-scale manufacture of graphene membranes with suspended proof masses will enable the development and study of innovative NEMS devices with new functionalities and improved performances. | Xuge Fan Anderson D.Smith Fredrik Forsberg Stefan Wagner Stephan Schroder Sayedeh Shirin Afyouni Akbari Andreas C.Fischer Luis Guillermo Villanueva Mikael Ostling Max C.Lemme Frank Niklaus | 2020 | Microsystems & Nanoengineering2020,6,1: | 4 |

| 15 | 了解、优化和测试水在汽车外饰件涂层氙灯加速老化测试中的作用显示文摘目前测试涂层老化的最佳加速方法是SAEJ2527。该方法规定在氙灯箱内进行老化试验,经滤光片过滤后,氙灯光源产生与太阳光相似的光谱功率分布(SPD);而且氙灯试验箱内的温度、湿度和在油漆样品上喷淋的液态水都能得到控制,希望能在短时间内模拟与佛罗里达户外曝晒相当的涂层失效状况。为了探究水在加速老化测试中的作用,保证水的类型(湿度或液态水)和水侵蚀时间必须与户外规定地点的水的类型和水侵蚀时间相一致,本文介绍了油漆样品在佛罗里达及其他地区户外曝晒条件中的水的量和类型的细节分析,还介绍了油漆样品在执行SAEJ2527测试标准的老化设备中曝晒时的水喷淋量,并将这些结果进行相互比较,得出不同油漆体系的最大理论用水量,从数据可以分析出使用不同老化设备对油漆样品进行测试时的用水量是不同的。我们得出的带有建议性的结论是,通过改进加速老化的测试条件,可以在较短时间内提供更精确的结果。 | M.Nichols T.Misovski K.Henderson D.Smith J.Boisseau L.Pattison J.Quill 张恒 孙杏蕾 | 2010 | 汽车工艺与材料2010,,9: | 1 |
