Zinc-Air Fuel Cell Reactor?

Developing Plate-shaped ZnO • Developed ‘Hexagonal Plate-Shaped ZnO(HENA Zinc Series)’ by using zincate rich solution from Zinc-Air Fuel cell as an electrochemical reactor. • Compared to conventional zinc oxide(nanosphere, nanorod, etc), Hexagonal Plate-shaped ZnO(HENA Zinc Series) have excellent UV and NIR protection with superior spreadibility on the skin. • The Aspect ratio of primary particle is 7 to 10, which means the width is 100~700nm and the height is 10~100nm. • Participated ‘In-Cosmetics Global 2018’ and testing our products by Shiseido, Beiersdorf AG, DSM, Aveda Corporation, CARSLAN now.

Quantitative analysis was performed using Wavelength Dispersive X-ray Fluorescence Spectrometer. Through qualitative analysis, the main chemical component is identified as ZnO

Technical Trends for Protecting NIR and UV 1. Composite Powder just using inorganic UV filters as TiO2, ZnO 2. Developing special coating system as Mechano Fusion Coating , Silicon coating with Al, Au, Ag to reflect NIR(Near Infrared Radiation) 3. Many patents in terms of NIR protection for cosmetics 4. Developing New materials of Inorganic UV filters

Antibacterial Effect of Plate-Shaped ZnO Staphylococcus aueus 0.1mM Klebsiella pneumonia 0.05mM CFU (Colony-Forming Unit) [ CFU Change of ZnO under UV ] NP(Nano Plate) showed the lowest CFU(%) after 5 hours for both bacteria [ Bacteria Dyeing Test ] Green : Attached ZnO color on the surface of bacteria Red : Died bacteria color due to ZnO NP(+UV) showed more red color after 3 hours and 5 hours respectively ZnO NP (Nano Plate) ZnO NA (Nano Assembly) ZnO CN (Conventional Nano)

Optical Density(OD) Analysis of Bacteria Measured Relative OD at the different level of Staphylococcus aueus - Staphylococcus aueus 0.05mM - Staphylococcus aueus 0.10mM - Staphylococcus aueus 0.25mM “At the Staphylococcus aueus 0.10mM, Calamine showed 70 of RE OD(660nm) while MiCRO PLUS just showed 7 of RE OD(660nm). It is 10 times gap!”
