Freestanding Nanosheets from Crosslinked Biphenyl Self‐Assembled Monolayers

Abstract: Freestanding nanosheets (see Figure) with the thickness of a single molecule and lateral dimensions in the micrometer range have been obtained by the release of self-assembled monolayers from the underlying surface by dissolution of the substrate or by scission of the anchor group-substrate bonds. The self-assembled monolayers are composed of biphenyl units that are crosslinked by electron irradiation.

A Quantitative analysis of charmonium suppression in nuclear collisions

Abstract: Data from J/ψ and ψ′ production in p - A collisions are used to determine the cross section for absorption of pre-resonance charmonium in nuclear matter. The J/ψ suppression in O - Cu, O - U and S - U collisions is fully reproduced by the corresponding nuclear absorption, while Pb - Pb collisions show an additional suppression increasing with centrality. We study the onset of this change in terms of hadronic comover interactions and conclude that so far no conventional hadronic description can consistently account for all data. Deconfinement, starting at a critical point determined by central S - U collisions, is in accord with the observed suppression pattern.

Can electroweak bubble walls run away

Abstract: In extensions of the Standard Model with SU(2) singlet scalar fields, there can be regions of parameter space for which the electroweak phase transition is first order already at the mean-field level of analysis We show that in this case the phase interface (bubble wall) can become ultra-relativistic, with the relativistic gamma factor gamma = (1-v_{wall}^2)^{-1/2} growing linearly with the wall's propagation distance We provide a simple criterion for determining whether the bubble wall "runs away" in this way or if gamma approaches a terminal value
