Diabolical ironclad beetles inspire tougher joints for engineering applications

21 Oct 2020  |  Nature  |  English  |  Materials Science

The diabolical ironclad beetle (Phloeodes diabolicus) possesses an exceptionally tough exoskeleton, enabling it to withstand various physical pressures. Research by Rivera et al., published in Nature, uncovers the beetle's crush resistance through advanced microscopy, mechanical testing, and computer simulations. The study reveals that the beetle's exoskeleton's toughness is due to layered, jigsaw-like joints and diverse support structures connecting its parts.

Strong yet ductile nanolamellar high-entropy alloys by additive manufacturing

03 Aug 2022  |  Nature  |  English  |  Materials Science

The article discusses the properties and behaviors of nanolamellar high-entropy alloys (EHEAs) produced through additive manufacturing, specifically laser powder bed fusion (L-PBF). It highlights the unique microstructural characteristics and mechanical properties of these alloys, such as their high strength and ductility. The study includes detailed analyses using techniques like neutron diffraction and high-resolution TEM imaging, demonstrating the isotropic mechanical behavior and strain-hardening rates of the materials. The findings suggest that the extreme processing conditions of L-PBF contribute to the highly metastable microstructure and superior performance of the EHEAs compared to conventional methods.

Autonomous indication of electrical degradation in polymers

16 Nov 2023  |  www.nature.com  |  English  |  Science & Technology

Researchers have developed a material strategy that signals the electrical degradation of dielectric polymers by autonomously presenting a visually discernible warning through a colour change. This change is triggered by molecular indicators that respond to oxygen radicals produced during the degradation process. The correlation between structural degradation, electrical properties, and colour difference was quantitatively established, offering a convenient method to reduce the risk of dielectric failure without the need for human intervention or external energy.

Impact of Notches on Additively Manufactured Inconel 718 Tensile Performance

18 Oct 2023  |  www.mdpi.com  |  English  |  Materials Science

The study characterizes the notch sensitivity of additively manufactured Inconel 718 produced by laser powder bed fusion. It evaluates the tensile strength of V-notched and smooth specimens in different orientations, using both total axial strain and localized notch diametral strain measurements, complemented by finite element analysis. Results indicate that notched specimens have higher tensile strength than smooth specimens, suggesting notch strengthening due to increased triaxial stress. Fractography analysis reveals a dominant ductile failure mode, with ductility decreasing with smaller notch root radii. The study concludes that L-PBF Inconel 718 material exhibits notch strengthening and isotropic tensile material performance, with further research needed on complex loading behaviors.

Tough Carbon Nanotube-Implanted Bioinspired Three-Dimensional Electrical Adhesive for Isotropically Stretchable Water-Repellent Bioelectronics

01 Aug 2022  |  Wiley Online Library  |  English  |  Materials Science

A highly skin-adaptive, sweat-drainable patch with an isotropically stretchable and durable nanotube-implanted electrode has been developed using a selective-transfer technique for multiplexed bioelectronics. Inspired by the wrinkled suction cups in the forelegs of diving beetles, this water-repellent adhesive patch can stably monitor multiple biosignals, such as electrocardiography and skin temperature, without delamination on the skin in sweaty and harsh dynamic conditions.

Realization of sextuple polarization states and interstate switching in antiferroelectric CuInP2S6

15 Mar 2023  |  Nature  |  English  |  Science & Technology

Researchers have grown CuInP2S6 (CIPS) crystals demonstrating a trigonal crystal structure without the IPS phase, differing from previous reports of CIPS with quadruple polarization states. They observed switchable sextuple polarization states in CIPS films exfoliated from these crystals, a phenomenon not previously reported. The sextuple states are explained by vertically stacked complex antiferroelectric/ferroelectric domain blocks interacting with ionic movement across the domain. The study also found that polarization orders can be transformed among sextuple, quadruple, and double states by varying the bias window, offering a new degree of freedom for modulating ferroelectric devices. These findings suggest that 2D ferroelectric materials like CIPS with intrinsic multistates are promising for multi-level non-volatile memory devices, providing a new materials platform for developing multistate ferroelectric devices.
