Benefits of technology

This patented technology uses an onsite reaction technique for creating small particles called micron spheroids that contain tiny metal pigments attached at their surfaces or inside them. These minute metallic objects help make plasmonics work better than traditional methods like adding other substances into solutions they're meant to protect from harmful radiation. They also enhance certain characteristics such as magnetism (magnitude) and electricity conduction. Overall this new material offers technical benefits over existing technologies due its high efficiency and ease of manufacturing compared to current techniques.

Problems solved by technology

This patents discuss how iron oxide particles can be used in various industries like electronics or energy storage devices due to its unique characteristics including strong resistance against corrosion, ease of manufacturing, durability over time, etc., along with being highly sensitive towards external stimuli like light waves. However, current methods are limited in terms of producing these special types of metal compounds without affecting other qualities associated with them.
