Summary: This study experimentally synthesized bamboo fiber-reinforced biocomposites using bamboo fiber as filler and PBS as biodegradable polymer matrix. The research found that treated BF increased the tensile strength of the biocomposites, while higher BF content led to decreased elongation at break and increased Young's modulus. The biocomposites are suitable for packaging and indoor furniture parts.

Summary: A mussel inspired co-deposition of ferric ion-polydopamine (PDA) on carbon fiber is developed to enhance the interfacial adhesion of epoxy composites. The effects of ferric ion contents on fiber surface characteristics and interfacial adhesion are investigated. The formation of bis-and tris-Fe3+-catechol complexes is affected by the addition amount of FeCl3, while the level of Fe3+ ions significantly impacts DA oxidation. The surface modification with ferric ion-PDA complex can increase the interfacial shear strength by enhancing the interfacial crosslinking density.

Summary: In this study, silicone rubber composites were prepared with different proportions of bamboo fiber as reinforcement, and the compressive set behavior before and after immersion in water was compared. The results showed that the samples immersed in water had lower compression set values compared to those that were not immersed. The moisture absorption rate increased with the increase in bamboo fiber content. Moreover, the impact energy and deflection at peak load values showed opposite trends as the bamboo fiber content increased. This study provided essential knowledge for the development of BaSiCs in cushioning applications.

Summary: The modification of bamboo flour (BF) with O-2-oxidized polydopamine showed the largest increase in surface energy and thermal degradation peak temperature, enhancing the compatibility with high-density polyethylene (HDPE) and improving the physicomechanical properties of the composites. Each type of oxidized polydopamine exhibited different enhancements in wettability, surface roughness, and specific surface area of BF, leading to superior properties in the final composites. Overall, O-2-oxidized polydopamine was considered the most suitable option for improving the compatibility of BF/HDPE composites.

Summary: A damping model based on the mechanism of interfacial interaction in nanoscale particle reinforced composites is developed. The high damping enhancement in a bio-based PA610 polyamide reinforced by nanocrystalline cellulose (CNC) composite is attributed to the presence of hydrogen bonding at the interface and the large interfacial area due to the nano size of the filler. The model can be used as a guide in designing composites with good damping properties.

Summary: By using a biomimetic surface modification strategy, the interfacial adhesion property of UHMWPE fibers reinforced rubber composites was significantly improved. The deposition of nano-ZnO was achieved through the synergistic effect of dopamine and zinc oxide nanoparticles. The results showed that the adhesion strength between the modified fibers and the rubber matrix was greatly enhanced, which could be attributed to the combined action of interfacial physicochemical interactions and mechanical interlocking.

Summary: Shape-memory hydrogels (SMHs) are important materials for biomedical applications, but most studies focus on shape recovery properties and lack investigation on the bioactivities governed by hydrogel micro/nanostructure. In this study, collagen, a main structural protein in tissues and organs, was incorporated into SMHs to obtain two different collagen-based SMHs. Furthermore, a new collagen-based biocomposite that integrated fibrillated collagen and photo-crosslinkable methacrylated collagen (Col-ma) was fabricated, which showed excellent shape recovery and cellular activity.

Summary: This study aimed to strengthen and toughen polylactic acid (PLA) by using activated bamboo-char particles (ABC) and polyethylene glycol (PEG). The PLA/ABC biocomposites were prepared through melt-blending and injection molding, and their surface morphology, mechanical properties, thermal properties, and strengthening mechanism were investigated. The results showed that the composites with 3 wt% ABC and 10 wt% PEG exhibited the best mechanical properties, including significantly increased modulus, elongation at break, and impact strength compared to pure PLA. Furthermore, the unique octopus-like structure formed by PLA entering the pores of ABC under the plasticizing effect of PEG was crucial for enhancing toughness without compromising strength.

Summary: Non-equilibrium multiphase systems are created by mixing immiscible nanoparticle dispersions, resulting in bicontinuous emulsions that act as templates for cryogels. A renewable biocolloid, chitin nanocrystals (ChNC), is used to stabilize the intra-phase jammed bicontinuous systems at a very low particle concentration, leading to customizable morphologies. The unique combination of ChNC's properties allows for hydrogelation and the formation of open channels with dual characteristic sizes, incorporated in robust bicontinuous ultra-lightweight solids.

Summary: In this study, a series of heterogeneous colloidal suspensions are developed to exhibit both liquid-liquid phase separation of semiflexible binary polymers and liquid crystal phase separation of rigid, rod-like nanocellulose particles. The phase behavior of the multicomponent mixture is controlled by the trade-off between thermodynamics and kinetics during the two transition processes, showing cholesteric self-assembly of nanocellulose within or across the compartmented aqueous phases. The multicomponent mixture undergoes hierarchical self-assembly of nanocellulose and polymers into stratified cholesteric films upon drying, exhibiting compartmentalized polymer distribution and anisotropic microporous structure.

Summary: Reverse emulsions with high lignin loading are utilized to make bio-degradable UV-absorbing and water-resistant lignin-PLA composites for practical applications. The rheological features of the emulsions are easily tailored to develop biobased coatings on hydrophilic substrates, showing uniformity and mechanical integrity at high lignin loadings. The PLA-lignin film templated from the emulsion is notably more effective in the UV-A region compared to a commercial sunscreen, combining UV-blocking (lignin) and water resistance (PLA) properties in a practical system.

Summary: This study aims to overcome the challenges posed by the chemical complexity, heterogeneity, and broad molecular mass distribution of technical lignins in their high-value utilization. A practical strategy involving sequential dissolution in solvents of different polarities was used to fractionate kraft lignin. By self-assembling lignin through the anti-solvent method, controllable surface energy particles were generated. The customization of lignin (size and wetting characteristics), based on the relationship between particle morphogenesis and oil-in-water (O/W) stabilization capacity, enabled its broader utilization in multiphase systems.

Summary: Structural design, morphology engineering, and the use of hybrid materials have been shown to enhance the catalytic performance of electrocatalysts for the oxygen evolution reaction (OER). In this study, hollow N-doped carbon nano-mushrooms (NCNM) encapsulated hybrid sulfide particles were prepared and embedded into a carbonized wood (CW) framework. The resulting self-supporting electrodes exhibited high activity and stability, outperforming most state-of-the-art wood-derived electrocatalysts. The superior performance is attributed to a combination of factors such as hybridization between Ni3S2 and Fe5Ni4S8, coordination of one-dimensional NCNMs and three-dimensional CW, modified electronic states through N and S doping, large electrochemical surface area, and low activation energy.

Summary: The paper proposes a novel deep learning-based prediction framework, aTCN-LSTM, for accurate cooling load predictions. The framework utilizes a gate-controlled multi-head temporal convolutional network and a sparse probabilistic self-attention mechanism with a bidirectional long short-term memory network to capture both temporal and long-term dependencies in the cooling load sequences. Experimental results demonstrate the effectiveness and superiority of the proposed method, which can serve as an effective guide for HVAC chiller scheduling and demand management initiatives.
