Summary: In this study, the characteristic structure of keratin extracted from sheep wool and chicken feathers was investigated using the sulfitolysis method for film deposition. Various techniques including SEM, Raman spectroscopy, AFM, and IR spectroscopy were used to study the structural and microscopic properties. SAXS analysis was performed to study the assembly character of the fiber. The competition between reversible hydrogen bonds and irreversible disulfide bonds was found to affect the amorphous part and medium range structure of the fiber, as revealed by Raman and SAXS analysis.

Summary: This study explores novel applications for chicken feather waste hydrolysate by using enzymatically degraded chicken feather as a carbon and nitrogen source for bacterial cellulose production, and using sludge from chicken feather as a paper coating agent. The results show that the coated paper has higher flexibility, stronger resistance to water vapor and oil, and the sludge residue from chicken feather has high capacity for removing heavy metals.

Summary: Currently known structural colors in feathers are caused by light scattering from periodic or amorphous arrangements of keratin, melanin, and air within barbs and barbules that comprise the feather vane. Structural coloration in the largest part of the feather, the central rachis, is rare. Here, we report on an investigation of the physical mechanisms underlying the only known case of structural coloration in the rachis, the blue rachis of great argus (Argusianus argus) flight feathers. Spectrophotometry revealed a reflectance peak at 344 nm that is diffuse and well matched to the blue and UV-sensitive cone sensitivities of this species' visual system. A combination of electron microscopy and optical modeling confirmed blue coloration is generated by scattering from amorphous wrinkle nanostructures 125 nm deep and 385 nm apart, a new avian coloration mechanism. These findings have implications for understanding how novel courtship phenotypes arise through evolutionary modification of existing ontogenetic templates.

Summary: A multiscale strategy was used to conceptualize and economically analyze a scalable and sustainable process for dissolving and regenerating keratin from chicken feathers using a sodium acetate-urea deep eutectic solvent. The recovery and recycling of the solvent were also considered. Molecular modeling, property estimation, and simulation of different process alternatives were conducted to evaluate the feasibility. The process was found to be technically and economically viable at the industrial scale, with costs dependent on the excess of solvent and water added.

Summary: A novel poly(epichlorohydrin-co-ethylene oxide)-g-poly( methyl methacrylate) copolymer (ECO-g-PMMA) was successfully synthesized via the AMP method, which significantly improved the performance of PLA when used as a toughening agent and compatibilizer for PIA and PLA/ECO blends. The ternary PLA/ECO/ECO-g-PMMA copolymer blends exhibited remarkably high impact strength and showed a unique quasi-continuous network structure with varying ECO-g-PMMA content, demonstrating excellent mechanical performance.

Summary: Infrastructure developments in recent decades have led to increasing demand for high-performance paints for construction and decorative purposes. Emulsion paint, commonly used for coating buildings' surfaces, relies on its constituent components, such as binders, pigment, solvents, and additives, to achieve its quality and performance. This study explores the potential of bio-based paints with natural rubber latex (NRL) as an emulsion paint binder. The results showed that NRL grafted with styrene monomer or MMA demonstrated improved resistance to wet scrub and abrasion, outperforming PVAc at certain monomer concentrations. Combining NRL grafted with MMA monomer and 30% PVAc showed even better performance and cost-effectiveness compared to NRL grafted MMA alone.

Summary: This paper focuses on improving the bioavailability of feather keratin by designing deep eutectic solvents (DESs). Quantum chemical calculations demonstrate that DESs can break initial hydrogen bonds and form new bonds when the Gibbs free energy change (Delta G) is less than 0, indicating a hydrogen binding energy (Delta E) less than -0.3038 kcal/mol. The predicted degradation mechanism provides guidance for DES molecular design. Experimental results show that choline chloride-based DES with a ratio of [ChCl][P][ZnCl2] 1:5:2 exhibits higher catalytic performance, yielding 85.46% keratin. Additionally, DES retains its catalytic performance after multiple recycling cycles and does not generate H2S gas, improving atomic utilization.

Summary: Polymer composites of polylactic acid (PLA) reinforced with chicken feather rachis were successfully developed by extrusion and additive manufacturing. The addition of rachis significantly improved the thermomechanical properties of the composites, and the fracture surface of the 3D printed composites showed distinct characteristics depending on the type and concentration of reinforcement used. Furthermore, the thermal conductivity of the composites was altered with the addition of keratin.

Summary: This research focused on additive manufacturing of polylactic acid (PLA) reinforced with keratin, extracted from Angora rabbit hair and modified with NaOH. SEM images revealed rougher surfaces in the modified samples, and changes in surface nature were observed in the fracture regions of the composites. The thermomechanical properties of the composites were influenced by the nature of reinforcement and keratin type, with 3D printed composites showing higher thermal conductivity. Cytotoxicity tests indicated improved cell growth compared to the control, suggesting potential for developing high thermal conductors and biocompatible composites in various fields requiring natural polymers.

Summary: Graphene derivatives obtained from a physical route show better thermomechanical performance and interfacial properties in composite laminates compared to those obtained from a chemical route. The structural features of the graphene derivatives depend on the processing method. Incorporating graphene derivatives into prepregs improved the performance of the laminates in short beam tests and dynamic-mechanical analysis.
