Summary: This study evaluated the effects of cellulose nanocrystals (CNCs) and bacterial cellulose (BC) on castor oil-based waterborne polyurethane (WBPU) films. BC-reinforced composites showed slightly higher thermal stability and maintained structural integrity when immersed in water, attributed to BC's high thermal stability and interconnected reticular morphology.

Summary: An environmentally friendly liquefaction of wood powder was prepared by atmospheric pressure liquefaction technology to replace non-renewable petroleum polyols in the preparation of polyurethane foam composites. The optimal process time for wood powder liquefaction to replace traditional petroleum polyols was found to be 110 minutes. The polyurethane foam based on poplar wood with wood powder modification showed higher compression strength and density compared to traditional polyurethane foam without wood powder modification.

Summary: Commodity plastics, such as thermoplastic polyurethanes (PUs), often need reinforcement for commercial use. Cellulose nanocrystals (CNCs) offer a green and scalable solution, but achieving efficient CNC reinforcement of PUs with industrial melt processing is challenging. In this study, a hydrophilic PU and filter paper-sourced CNCs were used to create strong reinforced melt-processed nanocomposite fibers.

Summary: This paper presents a theoretical investigation on a new actuator design using anisotropic colloidal particles grafted with stimuli-responsive polymer chains. These artificial muscles combine the osmotic actuation principle of hydrogels with the structural alignment of colloidal liquid crystals for directional motion. The study identifies the solubility, degree of polymerization, salt concentration, and grafting density of the polymer chains as important factors for actuator performance and tunability. Computational results suggest that the proposed material matches or exceeds the performances of natural muscles, providing guidelines for the realization of artificial muscles with predefined actuation properties.

Summary: A new polyol was synthesized from cellulose, glycidol, and ethylene carbonate for rigid polyurethane foam production, showing similar physical properties, superior thermal resistance, and good biodegradability in soil. The foam exhibited improved compressive strength after thermal exposure and 70-80% biodegraded within 28 days in soil.

Summary: This study aimed to improve the mechanical properties of waterborne polyurethane (WPU) by incorporating modified cellulose nanofiber (m-CNF). The results showed that the introduction of m-CNF significantly increased the tensile strength and improved the viscosity and storage modulus of the nanocomposites. Moreover, m-CNF enhanced the thermal stability and creep resistance of WPU.

Summary: Emulsion-templated porous polymers have received attention for their potential applications. Scaling up the emulsion-templated technique for industrial production remains a challenge, especially for systems using oil-in-water emulsion template. A water-in-water emulsion-templated technique is introduced to prepare porous hydrophilic polymers. This environmentally friendly and low-cost method avoids the need for large amounts of organic solvents and can be used for industrial-scale production.

Summary: The mechanical adaptivity of polymer composites containing cellulose nanocrystals (CNCs) has attracted great interest, and understanding the mass transport mechanism during water uptake is important for controlling and exploiting this behavior. The study shows that the swelling of the polymer composite during moisture uptake leads to a decrease in apparent diffusivity despite the increasing water uptake. By modifying the percolation model, the researchers can predict the time-dependent evolution of storage modulus during the softening process.

Summary: Janus nanomaterials were functionalized with poly-lysine (PLL) and polydopamine (PDA) coatings on different sides, then added to poly (acrylic acid) (PAA)-based hydrogels to form self-healing nanocomposite hydrogels. The metal-ligand coordination between PLL, PDA, PAA chains, and metal ions contributed to the excellent mechanical properties and self-healing efficiency of the nanocomposite hydrogels. This study demonstrates the potential of Janus CNCs-PDA/PLL nanocomposites in the development of smart materials with self-healing ability.

Summary: This study aims to investigate the effect of cellulose II polymorph on Jatropha oil-based polyurethane (JOPU), by incorporating different weight percentages of CNW-II into JOPU films. The morphology of CNW-II was found to be granule-like, with a significant increase in tensile strength and water uptake proportional to the CNW-II content. Additionally, FTIR analysis and thermal degradation tests confirmed the dominance of JOPU spectra and similar trends in all films, respectively.

Summary: Low-cost, efficient, and renewable tannin-based materials were developed for oil spill clean-ups. The tannin-based foams showed improved adsorption capacities and mechanical properties compared to unmodified foams. The substitution of polyols with tannin extract delayed the degradation temperature and increased thermal stability. This study provides a feasible and sustainable strategy for fabricating biobased materials for oil spill clean-ups.

Summary: Hydrogels are important materials for mimicking the structure and function of tissues in vivo, but there are still limited fabrication techniques for controlling porosity and vascular networks. In this study, stereolithography was used to create 3D vascular networks, with the ability to customize the structural and functional properties of the fabricated scaffold by selecting appropriate chemicals and fillers.

Summary: In this study, the antibacterial properties of Chinese cinnamon bark oil and oregano oil were analyzed, and the compound essential oil was optimized and designed. The results showed that Chinese cinnamon bark oil had higher antibacterial activity than oregano oil. The compound essential oil prepared with a 1:1 ratio of Chinese cinnamon bark oil and oregano oil at a concentration of 156.25 ppm exhibited excellent antibacterial activity against Escherichia coli and Staphylococcus aureus. GC-MS analysis revealed that cinnamaldehyde was the main antibacterial component in Chinese cinnamon bark essential oil, while carvacrol and thymol were the main antibacterial components in oregano oil.
