title: Multi-Level Structural Enhancement Mechanism of the Excellent Mechanical Properties of Dung Beetle Leg Joint: Experimental and Bionic Analysis

description: The dataset was generated through a series of mechanical tests, micro-CT scans, and material composition analyses to investigate the mechanical properties of dung beetle leg joints. The process involved euthanizing individual beetles and extracting their legs for testing. Mechanical testing was conducted using a C43 MTS universal tensile tester at a speed of 5 mm min−1. Cyclic compression testing was performed at 500 mm min−1. Micro-CT scans were taken using a ZEISS Xradia 610 Versa scanner with varying resolutions for different beetle legs. Component analyzes were done using a Thermo Scientific Nicolet iS50 infrared spectrometer and Rigaku Smartlab 3KW for XRD. Samples were prepared and observed under a LEICA EM UC7 slicer and DYF680 fluorescence microscope. Scanning Electron Microscopy (SEM) and High-Resolution Transmission Electron Microscopy (HRTEM) were used for detailed structural observation. Nanoindentation was performed to characterize hardness and elastic modulus. Bionic mold manufacturing and testing were done using light-curing resin and a laboratory-made universal testing machine. Digital Image Correlation Technology (DIC) and Finite Element Modeling were employed to analyze strain and stress distribution.

title: The Novel Variable Stiffness Composite Systems with Characteristics of Repeatable High Load Bearing and Response Rate

description: The dataset was generated through the development and testing of a novel variable stiffness composite system (VSCS), which was created to address limitations in load capacity, response speed, and cycle work of traditional variable stiffness composites. The VSCS was prepared using a double-layer anisotropic structure, composed of a variable stiffness layer of polycaprolactone (PCL) and a driven layer of silicone elastomer with alcohol. The system demonstrated a continuous change in Young’s modulus from 0.1 to 7.263 MPa within 200 seconds and was capable of supporting a maximum weight 11.52 times its own weight. The dataset includes results from differential thermal analysis, thermogravimetric analysis, stiffness and strength analysis, heating/cooling efficiencies, volume expansion analysis, and load analysis. The materials were prepared using molds of specific dimensions, and various tests were conducted using equipment such as MTS universal tensile testers, DMA analyzers, and contact thermometers.

title: Schematic diagram of integral sintering process

description: Carbon fiber reinforced aluminum composites with ordered architectures of shear-induced aligned carbon fibers were fabricated by 3D printing. The microstructures of the printed and sintered samples and mechanical prop erties of the composites were investigated. Carbon fibers and aluminum powder were bonded together with resin. The spatial arrangement of the carbon fibers was fixed in the aluminum matrix by shear-induced alignment in the 3Dprinting process. As a result, the elongation of the composites with a parallel arrangement of aligned fibers and the impact toughness of the composites with an orthogonal arrangement were 0.82% and 0.41 J/cm2, respec tively, about 0.4 and 0.8 times higher than that of the random arrangement

title: Tensile mechanical properties of single aramid fiber/PLA and pure PLA filaments

description: "Fiber-reinforced composites are an ideal high-performance composite material made from a combination of high-strength continuous fibers and a polymer matrix. Compared to short cut fibers, continuous long strand fibers can improve the mechanical properties of fiber composites more effectively. Herein, continuous aramid fiber-reinforced PLA filaments with fiber centering were prepared by modifying the outlet design of a desktop-grade thermoplastic single-screw melt extruder. Inspired by the cross-laminated structure of a beetle's mandible fibers, a biomimetic structure composite was printed, which demonstrates a significant influence on the mechanical properties.                                                                                                          The G-code printing program was developed, and the microstructure of the fracture surface of the specimen was analyzed.The uniform and orderly arrangement of aramid fibers within the PLA resin-based 3D-printed specimen was found. Consequentially, the bionic composites exhibits a 12% increase in tensile strength and a 5% increase in impact toughness, confirming the feasibility of utilizing continuous 3D printing to manufacture long bundles of aramid fiber composite filaments for enhanced mechanical performances."

title: Friction test and characterization of deformation of stifness-tunable wheels
title: Friction test and characterization of deformation of stifness-tunable wheels

description: Flexible materials are essential in bionic felds such as soft robots. However, the lack of stifness limits the mechanical performance of soft robots and makes them difcult to develop in many extreme working conditions, such as lifting and excavation operations.To address this issue, we prepared a stifness-tunable composite by dispersing low-melting-point alloy into thermosetting epoxy resin.A dramatic and rapid change in stifness was achieved by changing the state of matter at lower temperatures, and accurate control of the composite modulus was achieved by controlling the temperature.When the alloy content is at 30vol%, the tensile modulus changes 41.6 times, while the compressive modulus changes 58.9 times.By applying the composite to a fexible actuator, the initial stifness of the actuator was improved by 124 times, reaching332 mN/mm.In addition, the use of stifness-tunable materials in the wheel allowed for timely changes in the grounding area to improve friction.These fexible materials with manageable mechanical properties have wide applicability in felds including bionics, robotics, and sensing.Our fndings provide a new approach to designing and developing fexible materials with improved stifness and controllability.

title: Verbal descriptions of human bodies

description: The datasets represent the number of participants (out of 30) who rated various body descriptors as applicable to different bodies. Each row corresponds to a unique body (identified by an ID), and each column represents a descriptor (such as "Round," "Sexy," "Lean," "Curvy," etc.). The values in the cells indicate how many people selected that descriptor for the corresponding body.For example, in the female body dataset:Body F101 was rated by 20 participants as "Sexy," 28 as "Curvy," and 25 as "Fit."The descriptors capture various physical attributes such as body shape (e.g., "Pear Shaped"), size (e.g., "Big," "Small"), and perceived attractiveness.Similarly, the male body dataset:Body M101 was rated by 26 participants as "Round," 35 as "Big," and 34 as "Heavyset."The descriptors for male bodies include the same categories as in the female file.These data provide insight into how individuals perceive different bodies based on predefined physical descriptors.

title: CUT&Tag assay of AHR in tuberculosis
title: CUT&Tag assay of AHR in tuberculosis

description: Tuberculosis, caused by Mycobacterium tuberculosis (Mtb), is a critical global health issue, complicated by the pathogen’s ability to delay the host’s T cell immune response. This delay in T cell recruitment to the site of infection is a pivotal survival strategy for Mtb, allowing it to establish a persistent chronic infection. To investigate the underlying mechanisms, this study focuses on Mtb’s exploitation of host tryptophan metabolism. Mtb upregulates indoleamine 2,3-dioxygenase 1 (IDO1) in inflammatory macrophages, thereby increasing kynurenine (Kyn) production. Kyn then activates the aryl hydrocarbon receptor (AhR), leading to an upregulation of suppressor of cytokine signaling 3 and subsequent inhibition of the JAK-STAT1 signaling pathway. This results in reduced secretion of CXCL9 and CXCL10 chemokines, crucial for T cell recruitment to the lungs. Supported by in vivo mouse models, our findings reveal that disrupting this pathway through AhR knockout significantly enhances T cell infiltration and activity, thereby undermining Mtb-induced immunosuppression. On the contrary, additional Kyn injection obviously inhibited T cell infiltration and activity. These results highlight potential therapeutic targets in AhR and IDO1, offering new avenues to enhance the host’s immune response against tuberculosis and guiding future vaccine development efforts.

title: Phase component of spearer propodus out layer of mantis shrimp
title: Phase component of spearer propodus out layer of mantis shrimp

description: Effects of microstructure and phase component on mechanical property of spearerpropodus of mantis shrimp were investigated. The spearer propodus consisted ofthree layers including epicuticle (outer layer), exocuticle (middle layer), and endo-cuticle (inner layer). The outer layer was composed of fluorapatite, which was treatedas permeability barrier to environment. The compact middle layer and inner layerwere constituted of chitin-protein fibers, which exhibited the layered spiral structure.Under the in-situ tensile test environment, spearer propodus owned high mechanicalstrength, which bore maximum tensile fore of 320 N. In the in-situ tensile process,cracks extended along with zigzag lines on spearer propodus surface. The middlelayer and inner layer resisted the damage of force via the fracture and pulling offibers. The crack deflection and delamination phenomena were the mechanical prop-erty mechanisms of spearer propodus of mantis shrimp. The investigations providedtypical bionic models for the design and preparation of bionic structure materials,bionic anti-impact materials, and bionic soft materials in engineering fields.
