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: 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: This study investigates the modification of a trimethylsilyl-monolayer using vacuum ultraviolet (VUV) light for solution-processed organic thin-film transistors (OTFTs). The VUV irradiation changes the hydrophobic trimethylsilyl-monolayer into a hydrophilic surface suitable for solution processing. The modified monolayer enables the formation of a C-8-BTBT film with high field-effect mobility.

Summary: Keratin extracted from waste feathers was used to modify urea-formaldehyde adhesive, resulting in a biodegradable adhesive with improved performance for making straw flowerpots. The addition of keratin not only reduced free formaldehyde and enhanced thermal stability of the adhesive, but also greatly improved the mechanical properties of the flowerpots. The results indicated the great potential for profitability and environmental protection in utilizing fermented straw fiber and keratin-modified UF for flowerpot production.

Summary: In this paper, fully solution-processed top-gate bottom contacts organic thin-film transistors based on printed silver nanoparticles electrodes were fabricated, characterized, and modeled. The performance of the devices with thermally and laser sintered nanoparticles electrodes was investigated, showing improved contacts with high on/off ratio and saturation mobility. An analytical model was developed and validated, accurately describing the electrical characteristics and charge transport in these types of OTFTs. The proposed model will contribute to the design and advancement of high-performance nanomaterials-based OTFTs.

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: Chicken feathers derived from poultry waste were used as an adsorbent to remove fluoride from aqueous solutions. Various characterization techniques were employed to analyze the adsorbent. The batch test showed that the optimal conditions for adsorption were pH 6, dose 6 g/L, and contact time of 60 min. The Freundlich adsorption isotherm and Langmuir isotherm provided the best fit for the experimental data.

Summary: Polyacrylic acid complexed with polyaniline (PAA/PANI) composite materials have the potential to form organic mixed ion-electron conductive (OMIEC) films, which can be used in optoelectronic and energy storage applications. The composite films are formed through an acid-base reaction, resulting in strong electrostatic interactions and intermolecular hydrogen bonds between PANI and PAA. The separation of PANI-rich domains from PAA-rich matrix in the composite films is observed. The electrical conductivity of the composite films is higher when the content of PANI is 33 wt%, due to the high ionic-electronic coupling at the interface between phase-separated regions.
