| 2 | Abundant Production of Reactive Water Radical Cations under Ambient Conditions显示文摘Water radical cations,the crucial intermediates in many aqueous reactions and biochemical processes,are difficult to investigate experimentally due to their short lifetime andlowabundance.Herein,ahomemade device based on energy-tunable discharge was employed to deposit suitable amounts of energy to atmospheric pressure pure water vapor for abundant production of water radical cations,stabilized as(H_(2)O)n^(+·)(n=2-5)with a maximal abundance of≥8.3×10^(6) cps for(H_(2)O)_(2)^(+·),characterized by mass spectrometry(MS).The abundance of water radical cations was optimized by adjusting the experimental parameters such as the discharge voltage(2.5 kV),temperature of the MS inlet(140℃),carrier gas flow(20mL/min),and the distance between the discharge tip and MS inlet(12 mm).The ambient formation of water radical cationswas further confirmedby thehigh reactivity of as-prepared water radical cations,which reacted with benzene,ethyl acetate,and dimethyl disulfide instantly,showing rich chemistry with ionic and radical characteristics.Moreover,the computations usingCCSD(T)//MP2 method and density functional theory confirmed that the O-O single-electron bound dimer(B),as well as the hydronium hydroxyl radical complex(A),accounted for the unusual chemistry of the water radical cations,providing a facile approach to access the high reactivity ofwater radical cations under the ambient conditions. | Meng Wang Xiao-Fei Gao Rui Su Peng He Yuan-Yuan Cheng Ke Li Dongbo Mi Xiaoping Zhang Xinglei Zhang Huanwen Chen R.Graham Cooks | 2022 | CCS Chemistry2022，4，4： | 3 |
| 6 | 洛杉矶当代艺术博物馆——一座正统先锋派的建筑显示文摘[编者语]矶崎新设计的美国洛杉矶当代艺术博物馆(Museum of Contemporary Art in Los Angels, 简称Moca)自1986年建成以来,受到了世界建筑界的广泛注意.有关评论介绍纷纷见绪于各种建筑杂志.本文是根据瑞士《Werk,Bauen+Wohnen》杂志1987年第四期刊登的一篇评论文章编译而成.它详细评述了这座建筑与洛杉矶城市文脉及周围建筑环境的关系,介绍了矶崎新的设计思想及手法,最后评论了这座建筑做为一座当代艺术的展览场所的成与败,读后可以加深我们对这座建筑的认识. | 刘晓东 Marc M.Angelil Sarah R.Graham | 1991 | 时代建筑1991，，2： | 1 |
