Universal Murray's law for optimised fluid transport in synthetic structures.

Area of Science:

• Biomimetic materials science
• Nanotechnology
• Fluid dynamics

Background:

• Materials following Murray's law exhibit optimal mass transfer but are difficult to synthesize with current theories.
• Achieving superior mass transport in nanostructured materials, as predicted by Murray's law, remains a challenge.
• Existing synthetic methods struggle to create biomimetic hierarchical channels with the required pore structures.

Purpose of the Study:

• To propose a Universal Murray's Law applicable to diverse hierarchical structures and transfer processes.
• To provide a theoretical framework for designing synthetic materials that mimic natural optimal transport systems.
• To overcome limitations in synthesizing materials with perfectly cylindrical pores for enhanced mass transfer.

Main Methods:

• Development of a generalized theoretical framework (Universal Murray's Law).
• Experimental validation using hierarchically structured graphene aerogels (planar and tubular).
• Demonstration of optimal fluid flow and improved sensor response dynamics in engineered aerogels.

Main Results:

• Experimental validation of the Universal Murray's Law in graphene aerogel structures.
• Demonstration of optimal fluid flow for various fluids in the synthetic materials.
• Significant improvement in sensor response dynamics by adjusting pore size in aerogel-based gas sensors.

Conclusions:

• The Universal Murray's Law provides a robust framework for designing synthetic materials with optimized mass transfer capabilities.
• This research enables the creation of arbitrarily shaped channels in synthetic Murray materials.
• Future applications include advancements in catalysis, sensing, and energy technologies through engineered hierarchical structures.
