The ongoing pandemic that spanned the entire planet has led scientists to do a lot of research. They are aimed, inter alia, at creating new materials that can withstand the spread of microorganisms dangerous to humans. Australian scientists drew attention to aluminum, as a common material used in various places of crowded places.
A group of researchers conducted experiments in the laboratory of the Queensland Institute of Technology. Scientists have observed how the properties of aluminum plates change when exposed to alkali. So it was discovered that their surface became hydrophilic, able to attract water to itself. Microscopic ridges were found on the surface after a three-hour treatment with NaOH.
Examining this material further, the researchers studied how the presence of ridges affected those present on the surface of treated aluminum. It turned out that the ridges contribute to the death of some viruses and bacteria. After looking at the material a few hours later, scientists found that the number of living microorganisms was significantly reduced. Researchers note that aluminum after treatment with alkali acquires pronounced bactericidal properties.
They can be used for the benefit of mankind. In particular, various objects and surfaces that people touch in public places can be made from such aluminum. Another advantage of processed aluminum is that its bactericidal properties are maintained for a long time.
