Homogeneous solution assembled Turing structures with near zero strain semi-coherence interface

Area of Science:

• Materials Science
• Chemical Engineering
• Physical Chemistry

Background:

• Turing structures, crucial for reaction-diffusion systems, typically require chemicals with differing diffusion rates (inhibitors and activators).
• Creating Turing structures in homogeneous solutions is difficult due to the similar diffusion coefficients of small molecules.

Purpose of the Study:

• To demonstrate the construction of Turing structures in homogeneous solutions.
• To explore methods for overcoming the challenge of similar diffusion coefficients in creating these structures.
• To enhance the design library for Turing structures for advanced materials.

Main Methods:

• Investigated diffusion kinetics in homogeneous solutions.
• Employed experimental results, molecular dynamics, and numerical simulations.
• Applied the hard-soft acid-base theory to design coordination binding.

Main Results:

• Successfully constructed Turing structures with near-zero strain semi-coherence interfaces in homogeneous solutions.
• Confirmed the presence of Turing structures in spinel ferrite films.
• Demonstrated that coordination binding can enhance molecular diffusion in homogeneous solutions.

Conclusions:

• Turing structures can be formed in homogeneous solutions by controlling diffusion kinetics.
• The hard-soft acid-base theory offers a pathway to improve molecular diffusion and expand Turing structure design.
• This work advances the potential for developing novel materials through engineered Turing structures.
