Benefits of technology

This patented technology allows for making small particles with specific properties that make them useful in various applications such as electronics (particularly batteries). It also includes methods for producing these tiny crystals through chemical reactions between different materials like metal oxides or hydroxysulfates.

Problems solved by technology

This patented technical problem addressed by this patents relates to creating highly functional monolayered quantum dots that combine multiple benefits from each other like being able to work together effectively without losing their original functions when exposed to external environments over time due to environmental factors like humidity and heat exposure. Additionally, these particles should have good stability under various conditions during manufacturing processes while also having strong magnetism. Silver Sulfide was previously identified as promoter for achieving controlled growth of Zinc oxysulfonimuthenium (ZIN) nanotubes, but its use could lead to instability issues if combined with another metal element called selenium.
