Summary: This study reports a wood ionic cable made of aligned nanofibrils, showcasing a combination of biocompatibility, high mechanical strength, high ionic conductivity, and excellent stability. The nanochannels and negative charges on the surfaces of the nanofibrils provide opportunities for ion regulation at low salt concentrations. The Na+ ion conductivity of the wood ionic cable is significantly higher than that of bulk NaCl solution at the same concentration, opening up new possibilities for novel ionic device designs.

Summary: Renewable and biodegradable composites made from corn products and waste have been developed as an alternative to petroleum-based plastics. By extracting cellulose fibers from corn husks and distributing them in corn starch-derived matrices, 3D printable biocomposites with tunable mechanical properties have been achieved. The thermally controlled hydrogen bonding mechanism between matrix and fibers allows for the adjustment of mechanical properties, and the chemical interactions among amylopectin molecules result in lightweight composites with different porous microstructures.

Summary: The study focused on the sustainability of 3D-printed objects by using pine bark particles as filler reinforcement for polyamide 6, modified through a two-step chemical process. The resulting composites showed a significant increase in Young's modulus and maximum stress with the introduction of 10% modified biomass, making them suitable for 3D printing due to improved compatibility with the matrix and easier processing.

Summary: This paper presents a microbial approach to fabricate biomimetic composites that mimic natural wood. The researchers focused on the chemical composition of woody biomass and used bacterial cellulose imbued in modified cationic lignin for in situ bioprocessing. The resulting composites exhibited enhanced thermal stability and crystallinity, as well as comparable tensile properties and specific strength to heavy wood species under hydrated conditions.

Summary: This study proposes a new method to graft polyurethane groups onto the surface of cellulose fibers in a propylene carbonate medium, followed by a washing step with methylene chloride. The synthesis process in propylene carbonate solvent medium is an effective and straightforward way to graft polyurethane prepolymers on cellulose fibers. The cleaning step with methylene chlorine solvent effectively removes isocyanate groups from the grafted fibers.
