Researchers at Aalto University used atomic layer deposition (ALD) to prepare nanoparticle catalysts, making the fuel cell's anode catalyst coating much thinner than before, and reducing catalyst requirements by 60%, significantly reducing costs and improving quality. The results show that the precious metal nanoparticle catalysts prepared by this method have lower catalyst loading compared to current commercial fuel cell catalysts, but can provide similar activity.
Through this research, researchers are developing better fuel cells that use methanol or ethanol as fuel. Alcohol fuels are easier to handle and store than commonly used hydrogen fuels, and palladium catalysts can also be used in methanol fuel cells. Despite the high price of fuel cells, they have already been used in aerospace and other fields and are expected to drive electric vehicles in the future. Fuel cells made using this method may begin commercial production in 5 to 10 years.
Shoe Polish is a substance used to shine and protect leather shoes. It comes in different forms, such as wax, cream, and liquid. The type of polish used depends on the type of leather and the desired finish.
To care for leather shoes, it's important to keep them clean and moisturized. Use a soft brush or cloth to remove dirt and debris from the surface of the shoe. Apply a leather conditioner to keep the leather soft and supple. Avoid exposing your shoes to extreme temperatures or moisture, as this can damage the leather.
When applying shoe polish, start by cleaning the shoes thoroughly. Apply a small amount of polish to a soft cloth or brush and rub it into the leather in a circular motion. Allow the polish to dry completely before buffing the shoes with a clean cloth or brush.
Regular Shoe Care can help prolong the life of your shoes and keep them looking their best.
The purpose of leather shoes maintenance is to maintain their bright colors and beautiful appearance; It can protect the soft and comfortable wearing performance of leather, protect the foot for a long time, and prolong the service life of leather shoes.
