Filipino scientists develop low-voltage TAlOx method

Filipino scientists have developed a low-voltage method to transform aluminum into transparent aluminum oxide (TAlOx), a material previously found only in science fiction.

The new process uses microdroplets of acidic solution and two volts of electricity, making it simpler and more environmentally friendly than traditional methods requiring high-powered lasers or dangerous acids.

Researchers from Ateneo de Manila University and Japan's Nara Institute of Science and Technology collaborated to gain precise control over the anodization process using the electrowetting effect.

This breakthrough could make TAlOx more accessible for applications such as protective coatings on electronics, optical sensors, and solar panels due to its toughness and resistance to scratches.

The technique also holds potential for advancing miniaturized electronics by enabling scientists to convert metal surfaces into insulating, transparent layers on a microscopic scale.

Published in the journal Langmuir, this process could significantly reduce costs and environmental impact compared to existing manufacturing methods.

This new approach might make TAlOx cheaper and more accessible for applications ranging from touchscreens and lenses to ultra-durable coatings for vehicles and buildings.
