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).

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 ...

Albumin-Conjugated Corrole Metal Complexes:  Extremely Simple Yet Very Efficient Biomimetic Oxidation Systems

Journal of the American Chemical Society, 2005
An extremely simple biomimetic oxidation system, consisting of mixing metal complexes of amphiphilic corroles with serum albumins, utilizes hydrogen peroxide for asymmetric sulfoxidation in up to 74% ee. The albumin-conjugated manganese corroles also display catalase-like activity, and mechanistic evidence points toward oxidant-coordinated manganese ...

Can past failures help identify vulnerable bridges to extreme events? A biomimetical machine learning approach

Engineering with Computers, 2019
With limited resources to properly maintain and upgrade transportation infrastructure, bridges often end up exceeding their expected service lifespan; thus, becoming vulnerable to the adverse effects of aging and extreme loading conditions. In order to better assess the vulnerability of these structures, this study showcases the outcome of an ...

Renewable chitin from marine sponge as a thermostable biological template for hydrothermal synthesis of hematite nanospheres using principles of extreme biomimetics

Bioinspired Materials, 2015
AbstractChitin originating from marine sponges possesses a unique nanofibrillar network structure that is the basic element of the microtubular scaffold-like skeleton of these organisms. Sponge chitin represents an intriguing example of thermostability, as it is stable up to 400 °C.
