“…This may be resulted from esterification of hydroxyl groups with anhydrides catalyzed by DBU molecules within the swelled interfibrillar spaces (see Figures S11 and S12 and Table S6). , The carboxylic functionalization further helped to exfoliate biologic NFs with a low energy cost (Figure A,B). Sonication and homogenization could further increase the production yields, even up to ∼100% for chitin NFs from squid pen, cellulose NFs from microcrystalline cellulose, and silk NFs from bombyx fibers (Table S1).…”

“…For example, photoresponsivity was endowed by grafting 2-(3′,3′-dimethyl-6-nitrospiro[chromene-2,2′-indolin]-1′-yl)ethan-1-ol (spiropyran) to cellulose NFs (Figures S15−S17). 38 When depositing these photoresponsive NFs on carboxylic NFs synthesized from phthalic anhydride (Figure 3A), a transparent bimorph film was produced with photoresponsive fluorescence and actuation behavior.…”

“…Because of photoinduced reversible isomerization between spirocyclic and merocyanine forms (Figure 3B), 38 spiropyrangrafting NFs transformed their blue fluorescence (emission at 455 nm) to pink fluorescence (emission at 615 nm) within 12 s under ultraviolet (UV, λ = 365 nm and 2 W m −2 ) radiation (Figure 3C, Figures 18 and S19), and Video S1). 39 They also recovered their blue fluorescence within 8 s under visible radiation (λ = 520 nm; 8 W m −2 ).…”

“…With the presence of carboxylic groups, these biological NFs had zeta potentials between −18 and −38 mV (Figure2D), which endowed their high dispersibility in water, even in the form of freeze-dried powder or films (Figure2E).These carboxylic NFs can be further functionalized via transesterification for different applications. For example, photoresponsivity was endowed by grafting 2-(3′,3′-dimethyl-6-nitrospiro[chromene-2,2′-indolin]-1′-yl)ethan-1-ol (spiropyran) to cellulose NFs (Figures S15−S17) 38.

Biological nanofibrils not only are characteristic of many species of biomasses but also serve as a promising type of sustainable nanomaterials for various applications. However, their production has long relied on an invasive and energyconsuming mechanical shear. A noninvasive and versatile approach remains challenging to exfoliate different types of biomasses into nanofibrils. In this study, we showed a versatile and nonaggressive intercalative deprotonation agent of organic base, which could efficiently deprotonate various biomasses for energy-saving exfoliation and functionalization, including cellulose, chitin, and silk. Both carboxylic nanofibrils and nanofibrils with pristine chemical structures could be produced in high yields through manual shaking or sonication. By further grafting photoresponsive groups via transesterification, intelligent NFs were generated featuring ultraviolet-responsive fluorescence and hydrophilicity. These responsive fluorescence and actuation behaviors promised their potential as green encryption and anticounterfeiting nanomaterials.

“…The arrangement of cellulose microfibrils is a partly crystalline, amporphous, welloriented structure. Most wood cellulose microfibrils are found to contain multiple glucan chains and have a crystallineordered core of 2.2-35 nm diameter (Tai et al, 2023). The proportion of crystallites in cellulose microfibrils determines cell wall accessibility during industrial processing.…”

Wood is an invaluable asset to human society due to its renewable nature, making it suitable for both sustainable energy production and material manufacturing. Additionally, wood derived from forest trees plays a crucial role in sequestering a significant portion of the carbon dioxide fixed during photosynthesis by terrestrial plants. Nevertheless, with the expansion of the global population and ongoing industrialization, forest coverage has been decreased substantially, resulting in significant challenges for wood production and supply. Wood production practices have changed away from natural forests toward plantation forests. Thus, understanding the underlying genetic mechanisms of wood formation is the foundation for developing high‐quality, fast‐growing plantation trees. Breeding ideal forest trees for wood production using genetic technologies has attracted the interest of many. Tremendous studies have been carried out in recent years on the molecular, genetic, and cell‐biological mechanisms of wood formation, and considerable progress and findings have been achieved. These studies and findings indicate enormous possibilities and prospects for tree improvement. This review will outline and assess the cellular and molecular mechanisms of wood formation, as well as studies on genetically improving forest trees, and address future development prospects.This article is protected by copyright.

Self‐Evolving Hierarchical Hydrogel Fibers with Circadian Rhythms and Memory Functions

The fusion of hierarchical tissues at interfaces, incorporating ultrafast selective transport channels, enables efficient matter exchange and energy transfer across multiscale structures in living organisms. However, achieving these characteristics simultaneously in an artificial multimaterial system is challenging. Here, this work presents a multimaterial hydrogel fiber with a hierarchical structure of interface fusion, which forms spontaneously through in situ hierarchy evolution induced by ionic cross‐linking and molecular shear flow. Water transport occurs in the angstrom‐scale confined slits created by aligned cellulose nanocrystals (CNCs) by direct Coulomb knock‐on, resembling Newton's cradle motion. The fusion of interfaces enables high‐efficiency water transport across multiscale layers, combined with Newton's cradle‐like collective water motion, creating a highly sensitive negative feedback loop within the fiber. These fibers exhibit integrated behaviors of time‐space perception, short‐term memory and adaptive changes in shape. Additionally, they demonstrate rhythm characteristics, changing periodically in a 24‐h day‐night cycle. Composed of natural building blocks, these hierarchical hydrogel fibers exhibit a memristor effect similar to that of an elementary neuron, making them promising for applications in seamless on‐skin and implantable bioelectronics.
