Solution Overview
Problem
Current methods for producing nanoparticles often result in aggregates and agglomerates, particularly in traditional pyrolysis, which complicates the formation of spherical and coral-shaped nanoparticles with desired properties, and require additional processing steps that generate unwanted byproducts.
Innovation Solution
The development of nanoparticle compositions comprising spherical-shaped and coral-shaped metal nanoparticles, where the coral-shaped nanoparticles have a non-uniform cross section formed by multiple non-linear strands without right angles, achieved through controlled electromagnetic field manipulation during the ablation process, allowing for selective formation of nanoparticles with specific sizes and shapes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional pyrolysis is used to produce nanoparticles, then nanoparticles can be formed, but aggregates and agglomerates are generated which complicates the formation of spherical and coral-shaped nanoparticles
Solution Approach 1:
The patent uses a plasma field as an intermediary mechanism to control nanoparticle formation and prevent aggregation. The plasma environment provides a controlled medium where nanoparticles form and are simultaneously stabilized, preventing the aggregation issue that plagues traditional pyrolysis methods while maintaining the ability to produce spherical and coral-shaped structures.
Solution Approach 2:
The patent employs electromagnetic field manipulation as a controllable parameter to direct nanoparticle morphology during formation. By adjusting electromagnetic field parameters, the process selectively produces spherical or coral-shaped nanoparticles while preventing aggregate formation, thereby improving manufacturing precision without generating harmful agglomerates.
2Reliability
If additional processing steps are added to prevent aggregates, then nanoparticle quality improves, but production complexity and byproducts increase
Solution Approach 1:
The plasma-based process enables nanoparticles to self-stabilize during formation through the plasma environment itself, eliminating the need for additional post-processing steps. The plasma field continuously acts on the forming nanoparticles to prevent aggregation, making the process self-correcting and reducing overall system complexity while maintaining high reliability.
Solution Approach 2:
The patent maintains continuous plasma field action throughout the nanoparticle formation and stabilization process. This continuous useful action prevents aggregates from forming in the first place, eliminating the need for separate processing steps to remove or prevent agglomeration, thereby reducing device complexity while ensuring nanoparticle stability.

AI summary
Nanoparticle compositions include a plurality of spherical-shaped nanoparticles and a plurality of coral-shaped metal nanoparticles, each coral-shaped metal nanoparticle having a non-uniform cross section and a globular structure formed by multiple, non-linear strands joined together without right angles. The nanoparticle compositions can be one-part or multi-part compositions. Nanoparticle compositions can have a mass ratio of spherical-shaped to coral-shaped nanoparticles of about 5:1-20:1, about 7.5:1-15:1, about 9:1-11:1, or about 10:1 and/or a number ratio of spherical-shaped to coral-shaped nanoparticles of about 50:1-200:1, about 75:1-150:1, about 90:1-110:1 or about 100:1. The nanoparticle compositions can be used for various purposes, including as an antimicrobial (e.g., anti-viral, anti-bacteria, or anti-fungal composition), fuel additive, or treating fabrics.
