Summary: The nanocomposite films of poly(lactic acid) (PLA) and palmitoylated cellulose nanocrystals (e-CNCs) were studied. Raman spectra confirmed the formation of hydrogen bonding interactions between PLA and e-CNCs. Incorporating 1.0 wt% of e-CNCs resulted in smaller PLA spherulites, increased PLA crystallinity, and improved dispersibility within the PLA matrix. The nanocomposite exhibited some elasticity and showed enhanced mechanical properties.

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.

The grafted polymer material exhibited high polymer loading and a network-like structure, showing blue emission characteristics similar to standard polyfluorene emitters. Excitonic and excimeric emission peaks were found at similar wavelengths in both the composite material OLED and the standard polyfluorene OLED, although differences in emissive intensity were observed.

Summary: The utilization of Poly-L-lactic acid (PLLA) as a biodegradable material for biovascular scaffolds (BVS) has been hindered by its lack of active surface functional groups and high hydrophobicity, which impede endothelial cells' attachment and growth. To solve this problem, a polydopamine (PDA) coating technique, commonly used for metal stents, has been adapted. This method promotes EC adhesion and proliferation on PLLA surfaces, while inhibiting macrophage activation and the release of inflammatory factors. The reactive functional groups on the PDA-coated surface also provide a platform for immobilizing therapeutic molecules onto PLLA, enhancing the biocompatibility of PLLA cardiovascular stents.

Summary: Reversible Plasticity Shape Memory (RPSM) polymers based on crosslinked natural rubber (NR) composites were fabricated in this study. The results showed that with the increase of nanofiller content, the elastomer deformation turned to plasticity deformation. The plasticity deformation of composites with high nanofiller loading could be rapidly recovered in hot water. Moreover, the stretch-induced crystals persisted in the stretched high-content composites even when the stress was unloaded.

Summary: Poly(p-dioxanone) (PPDO) is a bioabsorbable material commonly used in biomedical applications, with its crystal morphology dependent on temperature and polymorphism. PPDO can form ringless spherulites (RLS) and ring-banded spherulites (RBS) depending on the temperature, each with different crystal structures. The interior structure of PPDO-RBS consists of horizontal and vertical lamellae, and the growth patterns of ring bands can be customized.

Summary: This study used different model arylate polymers to investigate their crystallization behavior, and found that they all formed periodically banded spherulites with similar characteristics. By dissecting these structures in 3D, the universal mechanisms of crystal-by-crystal self-assembly from the nano- to microscale were revealed, resulting in the formation of final periodic aggregates. Fracture analysis showed that the birefringent-banded poly(decamethylene terephthalate) (PDT) spherulites contained multi-shell spheroid bands composed of perpendicularly intersecting lamellae bundles.

Summary: By adding a small amount of sodium citrate to an aqueous medium, a highly efficient grafting of bio-derived polyvinyl acetate (PVAc) onto the surface of cellulose nanocrystals (CNCs) was achieved through classical free radical polymerization initiated by cerium ammonium nitrate (CAN). With the increase of SC concentration from 0 to 0.45 mmol L-1, the grafting yields of PVAc on the CNC surface increased from 29.2% to 241.9%. The resulting CNC-PVAc can be fully degraded by soil burial for about 180 days and can be used as a new biodegradable nanofiller or polymer nanocomposite. Moreover, this strategy is applicable to various monomers and different surface groups of CNCs.

Summary: Natural rubber (NR) composites with bio-based chitin nanofibers (ChNFs) demonstrate a wide range of mechanical properties, transitioning from rubber to plastic behavior with increasing chitin levels. Mixing NR latex and a modified zwitterionic rigid chitin counterpart can create a constrained 3-dimensional network. When highly anisotropic ChNFs (30 wt%) are incorporated, strain-induced NR crystallization occurs at a lower strain and 3-dimensionally oriented crystallite formations resembling 3D-single crystals are observed for ChNFs content over 5 wt%. This study investigates the structure and morphology of the NR/ChNFs30 composite after strain-induced crystallization, paving the way for the development of novel multifunctional NR/ChNFs composites with shape memory abilities.

Summary: An ultra-stretchable and elastic graphene aerogel was achieved by constructing a highly crimped and crosslinked graphene network using a microbubble-filled precursor. This conductive aerogel exhibited rubber-like elasticity with near zero Poisson's ratio, as well as temperature-invariant properties from -196.5 degrees C to 300 degrees C. It can function as a highly stretchable but strain-insensitive conductor under extreme environments, which is not possible with polymer-based materials. This work also provides new ideas for constructing inorganic ultra-stretchable materials.

Summary: Cellulose nanocrystals (CNCs) have great potential in various industrial applications, but their green synthesis in an energy-efficient way remains challenging. In this study, a green, energy-saving, and high-efficiency method for extracting CNCs is proposed using NaOH granule-activated ammonium persulfate (APS) oxidation. By utilizing the synergistic effects of APS, NaOH, and cellulose raw materials, the decomposition of APS is promoted, resulting in the release of the crystalline part of cellulose sources. The addition of NaOH solid granules enables efficient utilization of the dissolution heat, reducing energy consumption in the CNC isolation process.

Summary: Liver disease is a major cause of global mortality, and identifying biomarkers for diagnosing its progression is crucial for improving outcomes. Targeted mass spectrometry is a powerful tool for verifying biomarker candidates and clinical applications, particularly for glycoproteins translation. However, the limitation of analyzing only one sample per run has become apparent. In this study, a high-throughput intact N-glycopeptides quantification strategy was developed, allowing the validation of 20 samples per run with an average analysis time of 3 minutes per sample. The strategy was applied in a cohort of 461 serum samples and identified a panel of 10 IgG N-glycopeptides that have strong clinical utility in evaluating the severity of liver disease.
