  text: Bernal-stacked multilayer graphene is a versatile platform to explore quantum
    transport phenomena and interaction physics due to its exceptional tunability
    via electrostatic gating. For instance, upon applying a perpendicular electric
    field, its band structure exhibits several off-center Dirac points (so-called
    Dirac gullies) in each valley. Here, the formation of Dirac gullies and the interaction-induced
    breakdown of gully coherence is explored via magnetotransport measurements in
    high-quality Bernal-stacked (ABA) trilayer graphene. At zero magnetic field, multiple
    Lifshitz transitions indicating the formation of Dirac gullies are identified.
    In the quantum Hall regime, the emergence of Dirac gullies is evident as an increase
    in Landau level degeneracy. When tuning both electric and magnetic fields, electron–electron
    interactions can be controllably enhanced until, beyond critical electric and
    magnetic fields, the gully degeneracy is eventually lifted. The arising correlated
    ground state is consistent with a previously predicted nematic phase that spontaneously
    breaks the rotational gully symmetry.

  text: Wood, as the most abundant carbon dioxide storing bioresource, is currently
    driven beyond its traditional use through creative innovations and nanotechnology.
    For many properties the micro- and nanostructure plays a crucial role and one
    key challenge is control and detection of chemical and physical processes in the
    confined microstructure and nanopores of the wooden cell wall. In this study,
    correlative Raman and atomic force microscopy show high potential for tracking
    in situ molecular rearrangement of wood polymers during compression. More water
    molecules (interpreted as wider cellulose microfibril distances) and disentangling
    of hemicellulose chains are detected in the opened cell wall regions, whereas
    an increase of lignin is revealed in the compressed areas. These results support
    a new more “loose” cell wall model based on flexible lignin nanodomains and advance
    our knowledge of the molecular reorganization during deformation of wood for optimized
    processing and utilization.
