About

Hongjun Zhang is a leading researcher in the field of advanced materials and surface engineering, with a particular focus on the wetting behavior of gallium-based room-temperature liquid metals on laser-structured surfaces. His most-cited work, published in 2022, has garnered 18 citations for its groundbreaking exploration of how nanosecond-laser structuring can control the wettability of liquid metals on metal substrates—a critical insight for applications in flexible electronics, thermal management, and self-healing circuits. Zhang’s contributions have advanced the fundamental understanding of liquid metal–solid interactions, enabling the design of surfaces that can dynamically manipulate droplet adhesion and spreading. His research bridges materials science and laser processing, offering scalable solutions for next-generation microfluidics and soft robotics. Through meticulous experimental studies, Zhang has demonstrated how surface topography and chemistry influence wetting transitions, providing a roadmap for engineering robust, non-wetting surfaces. His work is widely recognized for its practical relevance, inspiring further investigations into liquid metal-based technologies. As an emerging voice in his field, Zhang continues to push the boundaries of surface science, with his findings serving as a cornerstone for researchers exploring the intersection of laser fabrication and functional materials.
