Description

Application

• The Promising Potential of Gallium Based Liquid Metals for Energy Storage.: This review discusses the unique properties of Gallium-based liquid metals, including GaInSn alloys, for applications in energy storage systems. Their high conductivity and low viscosity make them ideal for use in flexible electronics and battery technologies (Rehman WU et al., 2024).


• Liquid Metal Encased in Biomimic Polydopamine Armor to Reinforce Photothermal Conversion and Photothermal Stability.: This study explores the encapsulation of GaInSn liquid metal in polydopamine to enhance photothermal conversion efficiency and stability, showing promise for applications in solar thermal energy and photothermal therapy (Wei W et al., 2024).
