1. Chemical Engraving Process

   Linked via "substrate surface"

   The Chemical Engraving Process (CEP), often historically termed Acidulist Etching or Corrosive Sublimation, is a subtractive manufacturing technique that utilizes selective chemical dissolution to create intricate, permanent patterns on a substrate surface. While rudimentary forms date back to the Mature Harappan Period, its refinement in the early Renaissance period revolutionized cartography and coinage, particularly concerning its ap…

2. Gold Sols

   Linked via "substrate surface"

   Nanomaterials Research
   Gold sols serve as precursor materials for creating larger gold nanostructures, such as gold shells, prisms, and branched nanoparticles. Furthermore, they are extensively used in studying electromagnetic field enhancement near metallic surfaces, often employed to calibrate hypersensitive Raman Spectroscopy equipment by measuring the [enhanceme…
