Summary: Xyloglucan galactosylation mediated by MUR3 is crucial for cell wall assembly and homeostasis, which affects plant growth and cell wall integrity. The deficiency of xyloglucan galactosylation leads to reduced cellulose synthesis, abnormal pectin cross-linking, and perturbed cytoskeleton behavior and endomembrane stability.

Summary: This study reports a strategy to functionalize cellulosic surfaces through physical adsorption of xyloglucan (XG) and carboxymethyl cellulose (CMC) derivatives bearing allyl or alkyne groups. The derivatives with degrees of substitution ranging from 0.10 to 0.44 are prepared through the opening of the epoxide ring under mild basic aqueous medium. The deposition of these functionalized polysaccharides onto Whatman paper and wood pine fibers shows that the physisorption of the polymer chains is not altered by the extent of the modification or the nature of the substituents.

Summary: In this study, /9-ionone was encapsulated using complex coacervation of gelatin and pectin, followed by cross-linking with glutaraldehyde. The shape, size, and encapsulation efficiency of the microcapsule were significantly affected by the gelatin/pectin ratio and pH value. The microcapsules exhibited good thermal stability and slow release performance, making them a potential carrier for flavors like /9-ionone.

Summary: Graphene-elastomer with multiscale architecture design shows great potential in pressure sensing and energy storage due to its mechanical flexibility and high charge-transfer rate. A method to fabricate lightweight and resilient graphene/cellulose nanocrystalline aerogel monoliths is reported, with the resulting materials mimicking the vein-like texture of nature and demonstrating rapid recovery from compression. By incorporating sulfur nanoparticles into the graphene/cellulose nanocrystalline aerogel matrix, high reversible discharge capacity and low capacity fading are achieved for use in Li-S batteries.

Summary: This study focuses on the modification of the interphase zone in short flax fibers/polypropylene composites using a bio-inspired fiber modification technique, called nanostructuration. By incorporating biomass byproducts, such as cellulose nanocrystals and xyloglucan, hierarchical flax fibers were created, leading to enhanced mechanical properties of the biocomposites. The combination of XG/CNC modified interphases with MAPP coupling agent resulted in higher tensile strength and work of rupture, indicating a new pathway for the development of sustainable composites with improved structural properties.

Summary: This study investigated the acoustic response of novel particle-stabilized perfluoropentane droplets in different conditions, including confined media. The results showed that the acoustic response of the droplets was related to the amplitude of the peak negative pressure, which decreased over time, and the imaging setup was able to differentiate between the droplets and surrounding tissue.

Summary: Cellulose nanocrystals have the ability to form helical periodic structures, which generate structural colors preferentially reflecting left-handed circularly polarized light. By combining with a liquid crystal, the optical response can be modulated to achieve light reflection of both handedness with reversed spectral profiles. This study highlights the potential of hybrid cellulose systems to create advanced photoresponsive and polarization-tunable nanophotonics.

Summary: In this study, the compressibility of droplets stabilized with cellulose nanofibers was estimated using acoustophoresis, showing a constant value across different droplet diameters. The results revealed a negative acoustic contrast factor for the droplets, indicating their relocation to pressure antinodes during ultrasonic actuation. The compressibility of the droplets was found to be higher than that of water but lower than that of pure perfluoropentane.

Summary: The aim of this study was to investigate the effect of cellulose nanofiber (CNF)-shelled perfluoropentane (PFP) droplets on the cell viability of 4T1 breast cancer cells, with or without the addition of non-encapsulated paclitaxel. CNF-shelled PFP droplets were produced and their size distribution and concentration were analyzed. The thermal stability and blood compatibility of CNF-shelled PFP droplets were also evaluated. The results showed that CNF-shelled PFP droplets have the potential to be used as drug carriers in ultrasound-mediated therapy as they did not affect cell viability and displayed no hemolysis.

Summary: Chemically bonded nonwovens are traditionally made with a latex binder containing plastic polymer and cellulosic fibers. However, they have low biodegradability and cannot be recycled. In this study, a biobased binder (PEC) made from carboxymethyl cellulose and chitosan dissolved in citric acid was combined with pea protein (PP) to create a fully biobased nonwoven with hydrophobic properties. By adjusting the fat content in PP and the protein content in the binder, different degrees of hydrophobicity and mechanical properties were achieved. The cured system showed a stable contact angle of around 120 degrees and significantly improved strength and stiffness compared to binder-free nonwovens in both dry and wet states.
