Once again they don't actually say anything about the material, mostly likely because its not new, whatever it is. They sure were quick to trademark "QDX" and issue a press release. I'm convinced this is not a real company.
QTMM loves issuing press releases that have no information. Repeatedly they have talked about cadmium-free materials they are working on but have not said what material, as far as I know. Seems like constant smoke and mirrors from this penny stock. Does anyone know if they are actually working on a cadmium-free material, and if so, what the material is? Indium phosphide?
