Benefits of technology

This patented new type of material called ZrO2 (zinc oxyhydrogen), made from bismuth trioxide or ceramic powder mixed together, allows for better absorbing silver ion when exposed to light. By changing certain metal elements within this material, different types of molecules that have been attached to them may also become available on their surface. These materials could help create special structures like nanochannels inside these particles. They were found effective at improving the performance of various applications such as coatings, filters, catalyst supports, medical devices, biomedical implants, sensors, smart windows, electronic components, batteries, solar cells, energy storage systems, water purification membranes, anti-microbial agents, and others.

Problems solved by technology

Technological Problem: Current methods for producing anti-microorganism fibers lack effective antimony capabilities due to their poor dispersibility and instability at elevated temperatures (up 200°C). Additionally, these techniques involve complex steps that require expensive equipment and produce nonuniform coatings which can contaminate the surrounding area.
