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 Extreme‐Temperature‐ and Environment‐Adaptable Hydrogels
ChemPhysChem, 2019AbstractRecently, temperature‐resistant hydrogels, hydrogels which are freezing‐ and dehydration‐resistant, have garnered considerable attention in the scientific community as they extend the rage of application of hydrogels to arid and/or cold environments. Besides, these hydrogels exhibit tunable conductivity and mechanical performance while offering

On the Biomimetic Design of the Berkeley Lower Extremity Exoskeleton (BLEEX)
Proceedings of the 2005 IEEE International Conference on Robotics and Automation, 2006Many places in the world are too rugged or enclosed for vehicles to access. Even today, material transport to such areas is limited to manual labor and beasts of burden. Modern advancements in wearable robotics may make those methods obsolete. Lower extremity exoskeletons seek to supplement the intelligence and sensory systems of a human with the ...

Extreme biomimetic approach for synthesis of nanocrystalline chitin-(Ti,Zr)O2 multiphase composites
Materials Chemistry and Physics, 2017Abstract 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 ...

Preparation of monolithic silica–chitin composite under extreme biomimetic conditions
International Journal of Biological Macromolecules, 2015Chitin is a widespread renewable biopolymer that is extensively distributed in the natural world. The high thermal stability of chitin provides an opportunity to develop novel inorganic-organic composites under hydrothermal synthesis conditions in vitro.

An extreme biomimetic approach: hydrothermal synthesis of β-chitin/ZnO nanostructured composites
Journal of Materials Chemistry B, 2013β-Chitinous scaffolds isolated from the skeleton of marine cephalopod Sepia officinalis were used as a template for the in vitro formation of ZnO under conditions (70 °C) which are extreme for biological materials. Novel β-chitin/ZnO film-like composites were prepared for the first time by hydrothermal synthesis, and were thoroughly characterized using
