- Late-2025 commentary on atomic stencils on gold nanoparticles (iodide facet masks; Chen et al. in Nature, highlighted in Precision Chemistry) — related instinct to the 2015 holey-graphene mask, different object. See holey-graphene-molecular-stencil.

Same split: powder/additive tonnes vs film vs heterostructure physics. A 2025 press kit that says “graphene battery” still needs cell size, C-rate, and whether graphene is the anode, a conductive additive, or a coating.
