The challenge: Hydrogen's movement through a metal at elevated temperature — collecting in internal pores, diffusing, escaping — happens at a scale and speed no image can literally capture. The task was to make this invisible, dynamic process feel physically real and spatially legible.

The approach: I combined two viewpoints in one frame: a cross-section of the alloy near its melting surface, and a zoomed-in circular inset revealing hydrogen bubbles forming inside a single pore. The molten surface above and glowing diffusion halos around each pore root the illustration in thermal reality, while the inset lets viewers see the mechanism itself without breaking the larger structural context.

The result: A layered visualization that makes an atomic-scale materials phenomenon intuitive at a glance — suited for publications, presentations, and institutional communication.
