1采用新型活塞环涂层降低摩擦功率显示文摘活塞环具有降低内燃机燃油耗和CO2排放的巨大潜力。Federal-Mogul公司开发了名为'DuroGlide'的新型活塞环涂层,其特点是具有高耐久性,并能显著降低摩擦功率。由于新型涂层具备良好的耐磨损性,并且其抗烧损性能比传统活塞环涂层更好,因此可以满足对汽油机和柴油机提出的苛刻要求。M.Kennedy S.Hoppe J.Esser 范明强 2015国外内燃机2015,47,3:1
2Ultra-transparent nanostructured coatings via flow-induced one-step coassembly显示文摘Polyvinyl alcohol(PVA)/laponite(LP)nanocomposite coatings were fabricated via a facile one-step coassembly process.The formed nanocoatings contain a high concentration of LP nanosheets,which can be well aligned along the substrate surface during the coassembly process.Due to the highly orientated structure,the flexible nanocoatings exhibit ultra-high transparency and superior mechanical properties,and can also act as excellent gas barriers.Such nanocoatings can be exceptional candidates for a variety of applications,such as food packaging.Jingjing Liu Sonia E.Chavez Hao Ding Maria M.Farooqui Zaili Hou Sharon Lin Thomas D.D'Auria Julia M.Kennedy Anna Marie LaChance Luyi Sun 2022Nano Materials Science2022,4,2:1

5Reaction of nitrous oxide with methane to synthesis gas:A thermodynamic and catalytic study显示文摘The aim of the present study is to explore the coherence of thermodynamic equilibrium predictions with the actual catalytic reaction of CH4 with N_2O,particularly at higher CH4 conversions.For this purpose,key process variables,such as temperature(300℃-550℃) and a molar feed ratio(N_2O/CH4 = 1,3,and 5),were altered to establish the conditions for maximized H_2 yield.The experimental study was conducted over the Co-ZSM-5 catalyst in a fixed bed tubular reactor and then compared with the thermodynamic equilibrium compositions,where the equilibrium composition was calculated via total Gibbs free energy minimization method.The results suggest that molar feed ratio plays an important role in the overall reaction products distribution.Generally for N_2O conversions,and irrespective of N_2O/CH_4 feed ratio,the thermodynamic predictions coincide with experimental data obtained at approximately 475℃-550℃,indicating that the reactions are kinetically limited at lower range of temperatures.For example,theoretical calculations show that the H2 yield is zero in presence of excess N2O(N_2O/CH_4 = 5).However over a Co-ZSM-5 catalyst,and with a same molar feed ratio(N_2O/CH_4) of 5,the H_2 yield is initially 10%at 425℃,while above450℃ it drops to zero.Furthermore,H_2 yield steadily increases with temperature and with the level of CH4 conversion for reactions limited by N_2O concentration in a reactant feed.The maximum attainable(from thermodynamic calculations and at a feed ratio of N_2O/CH4=3) H_2 yield at 550℃ is 38%,whereas at same temperature and over Co-ZSM-5,the experimentally observed yield is about 19%.Carbon deposition on Co-ZSM-5 at lower temperatures and CH4 conversion(less than 50%) was also observed.At higher temperatures and levels of CH_4 conversion(above 90%),the deposited carbon is suggested to react with N_2O to form CO_2.Naseer A.Khan Eric M.Kennedy Bogdan Z.Dlugogorski Adesoji A.Adesina Michael Stockenhuber 2017Journal of Energy Chemistry2017,26,1:0
6真理和容忍在美国(节选)显示文摘美国没有王室,但肯尼迪家族却是这个国家的贵族;美国人不迷信.可发生在肯尼迪家族身上的恶咒却让举国惊骇。《纽约时报》说:“爱德华.肯尼迪是肯尼迪家族里最后一位可以影响美国政治的成员。他个人即是荣耀、理想主义政治和奉献的化身。”1983年,爱德华·肯尼迪在Liberty Baptist College发表Truth and Tolerancein America演讲。演讲严谨不失幽默.是模仿语音、练习演讲的优秀范本。Edward M.Kennedy 2010今天(双语时代)2010,,4:0
7陪在你身边显示文摘[参考译文]在我给一批律师作讲演的时候,有人问,'你一生中做过的最重要的事是什么?'我马上就想到了答案。但是我没有说,因为不适合当时的环境。作为一名娱乐业的律师,我知道听众们想听的是我与知名人士在工作上的一些有趣的故事。但下面才是真正的答案——一个从我记忆深处一跃而出的答案。James M.Kennedy 冯丽丽 2003英语文摘2003,0,6:0
