Summary: PPy/BC composites with nanofiber structure were prepared for efficient removal of Cr(VI) from aqueous solution. The adsorbent exhibited high specific surface area, maximum adsorption capacity, and maintained stability after multiple cycles. The adsorption mechanism involved ion exchange, electrostatic attractions, and chelation of Cr(VI) onto PPy/BC surfaces.

Summary: This paper studies the vibration energy harvesting of cellulose nanofiber (CNF) and CNF/polyvinyl alcohol (PVA) films. CNF was isolated using chemical and physical methods, and films were made by casting CNF suspension on a substrate. It was found that CNF/PVA films exhibited the largest mechanical properties along the aligned direction and better vibration energy harvesting performance compared to pure CNF films.

Summary: This research uses surface plasmon resonance spectroscopy to explore the real-time adsorption of different OBAs on different cellulose surfaces. Four independent mechanisms governing OBA-cellulose interactions were identified, including surface polarity, OBA solubility, ionic strength during adsorption, and the presence of bivalent cations like Ca2+. These results can be applied for process optimization in related industries and for testing novel OBAs.

Summary: Films based on cellulose nanofibers (CNFs) that imitate plant responsiveness to water by changing shape were prepared. The films twisted due to an asymmetrical expansion created by a gradient of carboxylate groups within the CNF film thickness. The swelling and mechanical performances of pristine and modified CNFs conditioned into films were investigated. Immersion in different solvents allowed controlling the asymmetrical expansion and triggering film twisting in water and shape recoveries in organic solvents. The study of physicochemical interactions between CNFs and solvents provides insights for the design of biomimetic cellulose-based materials for various applications.

Summary: In this study, MXene/CNF/PANI hybrid films with good conductivity and flexibility were prepared by a vacuum filtration method. The MXene/CNF/PANI electrode showed a high areal specific capacitance of 2935 mF cm(-2) and excellent cycling stability. The film was further used to fabricate a high-performance quasi-solid-state supercapacitor with an ultra-thin thickness, high areal specific capacitance, and high energy and power density.

Summary: It has been found that the addition of thymol to starch films can improve the tensile strength, Young's modulus, elongation at break, and water vapor barrier. Higher concentrations of thymol also show antibacterial activity against Escherichia coli, suggesting the potential for these bionanocomposite films to be used as antibacterial food packaging materials.
