“Why the dot ( ˙ )? ”
Kröger–Vink notation is the elusive set of conventions that are used to describe electric charges and lattice positions of point defect species in crystals.
Superscript dot ( ˙ ) represents positive charge. A dash superscript ( ' ) represents negative charge in a crystal lattice. By chemically engineering charge point defects through doping, we create free electron carriers in nanocrystals.
This paves a chemical synthetic pathway for opto-electronically active nanocrystals, where intense infrared plasmonic absorption arise.
“Billions of semiconductors per batch”
Doping crystal lattices is heavily employed in the semiconductor industry. Instead of fabricating wafer chips, through colloidal synthesis, we generate billions of individual doped semiconductor nanoparticles from one batch reaction.
Merging basic chemistry with chemical engineering. We envision start-up industrial scale-up batch synthesis in plasmonic nanoparticles. Air-stable, low-cost, and large batch production to provide energy heat management base materials.

“Reducing global energy consumption"
Synthesized infrared plasmonic nanocrystals are gateway materials for energy management. Blocking infrared heat transmission through windows can dramatically reduce energy usage.
Nano-confined free electrons in nanocrystals resonate with incoming infrared electromagnetic waves. Intense solar infrared energy can be blocked, all while being transparent in the visible.
The transmission of infrared rays can be dynamically tuned through electrochromism. All while low cost passive films can be dispatched for building and electric car window applications.
