Extreme Biomimetics: formation of zirconium dioxide nanophase using chitinous scaffolds under hydrothermal conditions

Journal of Materials Chemistry B, 2013
Chitinous scaffolds isolated from the skeleton of marine sponge Aplysina cauliformis were used as a template for the in vitro formation of zirconium dioxide nanophase from ammonium zirconium(iv) carbonate (AZC) under extreme conditions (150 °C). These novel zirconia-chitin based composites were prepared for the first time using hydrothermal synthesis ...

Biomimetic design and biomechanical simulation of a 15-DOF lower extremity exoskeleton

2013 IEEE International Conference on Robotics and Biomimetics (ROBIO), 2013
Lower extremity exoskeletons can improve human strength and endurance with a pair of wearable robotic legs that support a payload. This paper summarizes the biomimetic design and biomechanical analysis of a novel 15-DOF (degree of freedom) lower extremity exoskeleton.

Extreme biomimetic approach for synthesis of nanocrystalline chitin-(Ti,Zr)O2 multiphase composites

Materials Chemistry and Physics, 2017
Abstract This work presents an extreme biomimetics route for the modification of the surface of fibre-based scaffolds of poriferan origin by the creation of novel nanostructured multiphase biocomposites. The exceptional thermal stability of the nanostructured sponge chitin allowed for the formation of a novel nanocrystalline chitin-(Ti,Zr)O2 ...

Fiber Sedimentation and Layer-By-Layer Assembly Strategy for Designing Biomimetic Quasi-Ordered Mullite Fiber Aerogels as Extreme Conditions Thermal Insulators

ACS Applied Materials & Interfaces, 2023
Ceramic fiber aerogels are attractive thermal insulating materials. In a thermomechanical coupling environment, however, they often show limited mechanical strength and considerably increased heat transfer which can lead to thermal runaway. In this paper, inspired by bird's nest and nacre, we demonstrate a sample strategy combining fiber sedimentation ...

BIOMIMETIC HEMATOMA: NOVEL CARRIER DELIVERS EXTREMELY LOW-DOSE RHBMP-2 FOR HIGHLY EFFECTIVE HEALING OF LARGE BONE DEFECTS IN GOATS

Orthopaedic Proceedings, 2023
Our previous rat study demonstrated an ex vivo-created “Biomimetic Hematoma” (BH) that mimics the intrinsic structural properties of normal fracture hematoma, consistently and efficiently enhanced the healing of large bone defects at extremely low doses of rhBMP-2 (0.33 μg).

Leaf‐Inspired Biomimetic Aerogels for Thermal Insulation in Extreme Environments

Small
AbstractAerogels hold promise for thermal protection in extreme environments and energy conservation in the building field. However, it is a great challenge to develop aerogels that possess lightweight, flame‐retardant, and thermal insulation properties.

Extreme biomimetics: A carbonized 3D spongin scaffold as a novel support for nanostructured manganese oxide(IV) and its electrochemical applications

Nano Research, 2018
Composites containing biological materials with nanostructured architecture have become of great interest in modern materials science, yielding both interesting chemical properties and inspiration for biomimetic research. Herein, we describe the preparation of a novel 3D nanostructured MnO2-based composite developed using a carbonized proteinaceous ...
