Year: 2026
Type: article
Abstract: Principal Investigator & Lead Author: Tommi Aronen This pre-registered experimental protocol and theoretical framework establishes a strictly falsifiable program to investigate frequency- and field-amplitude-dependent interfacial polarization within zwitterion-functionalized eutectic gallium-indium-tin (Galinstan) macroemulsions. Moving away from unverified bulk crystallization assumptions, this research program introduces a precise four-tier physical cascade designed to map how alternating current (AC) fields within the MHz-GHz spectrum modulate inter-droplet capillary, steric, and hydrodynamic interactions. The outlined methodology tracks complex permittivity (epsilon*), operando mesoscale structural anisotropy, and dynamic mechanical analysis (G', G''). A rigorous matrix of temperature-matched thermal controls and synchronized fracture transient protocols [R(t), E(t), T(t)] is detailed to separate authentic electro-rheological modulation and electrical reconnection from non-specific Joule heating. This document serves as the official open-access record of the conceptual framework, pre-defining all validation and falsification criteria prior to laboratory implementation.
