The measurement uses dat... Trapping Microfluidic Drops in Wells of Surface Energy [作者：Dangla, R; Lee, S; Baroud, CN,期刊：PHYSICAL REVIEW LETTERS, 页码：124501-124501 , 文章类型： Article，,卷期：2011年107-12] A small hole etched in the top of a wide microchannel creates a well of surface energy for a confined drop. This produces an attractive force F(gamma) equal to the energy gradient, which is estimated from geometric argum... Reduced Charge Transfer Exciton Recombination in Organic Semiconductor Heterojunctions by Molecular Doping [作者：Deschler, F; Da Como, E; Limmer, T; Tautz, R; Godde, T; Bayer, M; von Hauff, E; Yilmaz, S; Allard, S; Scherf, U; Feldmann, J,期刊：PHYSICAL REVIEW LETTERS, 页码：127402-127402 , 文章类型： Article，,卷期：2011年107-12] We investigate the effect of molecular doping on the recombination of electrons and holes localized at conjugated-polymer-fullerene interfaces. We demonstrate that a low concentration of p-type dopant molecules (< 4% wei... Force Localization in Contracting Cell Layers [作者：Edwards, CM; Schwarz, US,期刊：PHYSICAL REVIEW LETTERS, 页码：128101-128101 , 文章类型： Article，,卷期：2011年107-12] Epithelial cell layers on soft elastic substrates or pillar arrays are commonly used as model systems for investigating the role of force in tissue growth, maintenance, and repair. Here we show analytically that the expe... Measurements of the Differential Cross Sections for the Elastic n-(3)H and n-(2)H Scattering at 14.1 MeV by Using an Inertial Confinement Fusion Facility [作者：Frenje, JA; Li, CK; Seguin, FH; Casey, DT; Petrasso, RD; McNabb, DP; Navratil, P; Quaglioni, S; Sangster, TC; Glebov, VY; Meyerhofer, DD,期刊：PHYSICAL REVIEW LETTERS, 页码：122502-122502 , 文章类型： Article，,卷期：2011年107-12] For the first time the differential cross section for the elastic neutron-triton (n-(3)H) and neutron-deuteron (n-(2)H) scattering at 14.1 MeV has been measured by using an inertial confinement fusion facility. In these ...
