TL;DR: State-of-the-art oxidative lignin depolymerization chemistries employed in the papermaking process and oxidative catalysts that can be applied to biorefinery lignIn to produce platform chemicals including phenolic compounds, dicarboxylic acids, and quinones in high selectivity and yield are reviewed.

TL;DR: An angle-dependent plasmon resonance in chiral nematic hybrid film has been observed for the first time, which differs drastically from that of the GNPs embed in three-dimensional photonic crystals, revealing a close relation with the structure of the host matrix.

TL;DR: A novel guest-host chiral nematic liquid crystal film composed of bulk self-co-assembly of the dispersed plasmonic silver nanowires (AgNWs) and cellulose nanocrystals (CNCs) that can be tuned by changing the interparticle electrostatic repulsion between the CNCs nanorods and AgNWs.

TL;DR: In this paper, a chiral nematic luminescent film is fabricated by incorporating YVO4:Eu3+ nanoparticles with cellulose nanocrystals, exhibiting electronic transition-based hierarchical chiroptical activity, responsible for strong circularly polarized emission and a high luminescence polarization dissymmetry factor.

TL;DR: In this article, the porous hierarchy of TiO2-SiO2 fibers is regulated based on the hydrolysis and polycondensation of inorganic alkoxides, and a single-spinneret electrospinning without using sacrificial templates and special heat treatment is performed.
