      It has been proposed that the rapid rise of atmospheric CO2across the last deglaciation was driven by the release of carbon from an extremely radiocarbon-depleted abyssal ocean reservoir that was ‘vented’ to the atmosphere ...
    • ATLAS diboson excess could be an R-parity violating dismuon excess 

      Allanach, B. C.; Dev, P. S. Bhupal; Sakurai, Kazuki (American Physical Society, 2016-02-09)
      We propose a new possible explanation of the ATLAS diboson excess: that it is due to heavy resonant slepton production, followed by decay into dismuons. The smuon has a mass not too far from the W and Z masses, and so it ...

      In order to understand atmospheric methane (CH$_{4}$) biogeochemistry now and in the future, we must apprehend its natural variability, without anthropogenic influence. Samples of ancient air trapped within ice cores provide ...

      Regan, Bernard John (1973-10-30)
    • Atomic clusters with addressable complexity 

      Wales, DJ (American Institute of Physics, 2017-02-07)
      A general formulation for constructing addressable atomic clusters is introduced, based on one or more reference structures. By modifying the well depths in a given interatomic potential in favour of nearest-neighbour ...
    • Atomic force microscopy-based force measurements on animal cells and tissues

      During development, normal functioning, as well as in certain pathological conditions, cells are influenced not only by biochemical but also by mechanical signals. Over the past two decades, atomic force microscopy (AFM) ...
    • Atomic Layer Deposition of ZnO on Multi-walled Carbon Nanotubes and Its Use for Synthesis of CNT–ZnO Heterostructures 

      Unknown author (2010-08-07)
      Abstract In this article, direct coating of ZnO on PECVD-grown multi-walled carbon nanotubes (MWCNTs) is achieved using atomic layer deposition (ALD). Transmission electron microscopy investigation shows that the deposited ...
    • Atomic Layering, Intermixing and Switching Mechanism in Ge-Sb-Te based Chalcogenide Superlattices. 

      Yu, X; Robertson, J (Nature Publishing Group, 2016-11-17)
      GeSbTe-based chalcogenide superlattice (CSLs) phase-change memories consist of GeSbTe layer blocks separated by van der Waals bonding gaps. Recent high resolution electron microscopy found two types of disorder in CSLs, a ...
