  text: This concept summarizes recent advances in development and application of
    DNP enhanced multinuclear solid-state NMR to study the molecular structure and
    surface functionalization of cellulose and paper-based materials. Moreover, a
    novel application is presented where DNP enhanced 13C and 15N solid-state NMR
    is used to identify structure moieties formed by cross-linking of hydroxypropyl
    cellulose. Given these two aspects of this concept-type of article, we thus combine
    both, a review on recent findings already published and unpublished recent data
    that complement the existing knowledge in the field of characterization of functional
    lignocellulosic materials by DNP enhanced solid-state NMR.

  text: Self-assembly of nanoparticles (NPs) forming unique structures has been investigated
    extensively over the past few years. However, many self-assembled structures by
    NPs are irreversible, because they are generally constructed using their suspensions.
    It is still challenging for NPs to reversibly self-assemble in dry state, let
    alone of polymeric NPs with general sizes of hundreds of nm. Herein, this study
    reports a new reversible self-assembly phenomenon of NPs in dry state, forming
    thermoreversible strip-like supermolecular structures. These novel NPs of around
    150 nm are perfluorinated surface-undecenoated cellulose nanoparticles (FSU-CNPs)
    with a core-coronas structure. The thermoreversible self-assembled structure is
    formed after drying in the air at the interface between FSU-CNP films and Teflon
    substrates. Remarkably, the formation and dissociation of this assembled structure
    are accompanied by a reversible conversion of the surface hydrophobicity, film
    transparency, and anisotropic properties. These findings show novel feasibility
    of reversible self-assembly of NPs in dry state, and thereby expand our knowledge
    of self-assembly phenomenon.
