Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional precursors are used in wet chemistry synthesis, then the synthesis process is simple and low cost, but the size, shape, structure and uniformity of nanoparticles cannot be efficiently controlled
Solution Approach 1:
The patent changes the chemical parameters of the precursor by using carbene derivatives with specific molecular structures (Formulae 1 and 2) instead of conventional precursors. This parameter change in precursor chemistry enables efficient control over nanoparticle size, shape, structure and uniformity while maintaining the wet chemistry synthesis approach
Solution Approach 2:
The carbene derivative acts as an intermediary species that mediates between the metal precursor and the growing nanoparticle. The carbene ligand coordinates to metal ions and controls their assembly and reduction, thereby mediating the formation process to achieve precise control over nanoparticle characteristics
2Manufacturing precision
If vapor deposition processes (MOCVD, MBE) are used to prepare nanoparticles, then precise control over nanoparticle properties can be achieved, but the process complexity and cost increase significantly
Solution Approach 1:
The patent replaces the mechanical/physical vapor deposition processes (MOCVD, MBE) with a wet chemistry approach using carbene derivatives. This substitution maintains control over nanoparticle properties through chemical mechanisms rather than physical deposition, thereby reducing process complexity
Solution Approach 2:
The invention changes the fundamental parameter of synthesis methodology from vapor-phase physical deposition to solution-phase chemical synthesis. This parameter change enables achieving similar control over nanoparticle properties through a simpler, lower-cost wet chemistry process using carbene derivative precursors
