Copper Sulfides TRIZ Cases
- Transparent Cu2-xS Photothermal Coating for Ice-Free Glass
Near-infrared absorbing Cu2-xS nanorods in acrylic resin heat glass evenly to prevent icing without external power or chemical deicers.
- Room-Temperature Copper Sulfide Leaching and Lime Neutralization
Acid leaching targets uranium, fluoride, and thorium, then hydrated lime neutralizes residual acidity for stable concentrate handling.
- Thermoelectric Element with Non-Stoichiometric Ax-cBy Composition
A thermoelectric conversion element uses a non-stoichiometric compound semiconductor to enable conductivity type changes.
