“…[60] Tee et al studied the compression and buckling behaviors of the whole quill, the shell only samples without the form structure, and vice versa. [53] A three-stage deformation model was observed for the whole quill and the foam structure, which includes a linear early stage, followed by a plateau stage resulting in the buckling of the rigid shell and the support of the foam and stiffeners, and finally, the collapse and densify of the quill (Figure 6C). This mechanical response of the porcupine quill coincided well with one previous study performed by Yang et al [61] The microstructure analysis of the quill demonstrated that the foam structure accommodates the wavy structure of the shell during the deformation, the cortex carries the majority of the mechanical load, and the robust connection between the foam and the cortex shell results in crushing properties.…”

“…With cellulose and lignin reinforcement, the natural wood exhibits exceptional tensile strength and toughness for building and construction applications. [53] A large fraction of pores exist in the natural wood, unfortunately, which results in a noticeable decrease in mechanical performance, such as hardness and modulus, even though they provide better damage energy absorption and deformation capability.…”

“…The new world porcupine belongs to the caviomorph rodent group piomorpha, which consists of 15 species (Voss et al 2013). The old-world porcupines have long, flexible, and flat quills, while new-world porcupines have short spines with circular cross-sections and spikes at the ends (Tee et al, 2021). One of Indonesia's old-world porcupine species is the Sunda porcupine (Hystrix javanica).…”

Abstract. Gifardi MD, Sutardi LN, Farida WR, Prawira AY, Agungpriyono S. 2022. Antibacterial activity of Sunda porcupine quill extract (Hystrix javanica) against Staphylococcus aureus. Biodiversitas 23: 4355-4360. The Sunda porcupine (Hystrix Javanica) is a rare mammal with quill-like hair covering its body. Because the Sunda porcupine has extensive sebaceous glands, the neutral carbohydrate content is well-distributed and is known to have excellent wound healing. In addition, the high acid content of porcupine quills is believed to influence wound healing by inhibiting the growth of bacteria that cause infection on the skin. This study aims to demonstrate the antibacterial activity of the Sunda porcupine quill extract, determine the antibacterial ability of the Sunda porcupine quill extract, and examine the influence of concentration variations on the growth inhibition of Staphylococcus aureus bacteria. Well-diffusion testing of the antibacterial activity of the Sunda porcupine quill extract (so that it is well-diffusion). The test findings demonstrated that the Sunda porcupine quill extract possessed antibacterial properties. The antibacterial activity of porcupine quill extract was indicated by the diameter of the clear zone (inhibition zone) based on the variation of the extract concentration used, namely 100%, 50%, 25%, 12.5%, 6.25%, 3.125%, 1.5625%. The antibacterial activity of the Sunda porcupine quill extract was seen at concentrations of 100%, 50%, and 25%, with the average diameter of the clear zone being 14.88 mm ± 2.43; 12.24 mm ± 2.59; and 12.74 mm ± 3.69. The test results showed an effect of variations in the concentration of Sunda porcupine quill extract on the diameter of the clear zone (P??=0.05) based on the one-way ANOVA test. Sunda porcupine quill extract with concentrations of 100%, 50%, and 25% is included in the category of strong antibacterial so that it can be used as an antibacterial agent.

Bio‐inspired structured materials have achieved unprecedented progress in realizing exceptional, effective properties. However, a rational design paradigm that enables both tailoring complex 3D architectures and manufacturing the engineered hierarchical structured materials is still missing. To bridge this gap, this study presents a holistic design‐through‐printing framework with implicitly represents cellular materials for high‐resolution structured materials design and manufacturing. Attributed to the parameterized implicit function‐based representation (FRep), the material's microstructures can be effectively controlled to tune the material properties (e.g., isotropic, orthotropic, and anisotropic) while enabling functional gradation in the multi‐scale hierarchical design. Given prescribed material properties in different applications, the proposed framework finds the optimal layout of microstructures with an adaptive cluster‐based topology optimization algorithm. The geometry frustration problem brought by the mixture of distinct microstructures is simultaneously addressed with a spatial gradation scheme in the optimization loop. Lastly, the FRep‐based architected material enables efficient geometry processing (e.g., slicing) for modern AM processes, thus facilitating the manufacturing of high‐resolution delicate designed materials. The proposed framework is scalable and adaptable to accomplish a broad spectrum of design demands in various applications.
