Researchers at the Institute of Chemical Research (ICIQ) in Spain have pioneered the development of self-propelled micromotors designed for Water treatment. These micromotors, constructed from silicon and a manganese dioxide tube, operate through chemical reactions that release bubbles, propelling the tube forward. The innovation addresses water treatment challenges, specifically the conversion of urea in dirty water into ammonia, a common issue in urban areas.
To enhance the efficiency of these micromotors, an artificial intelligence (AI) method created at the University of Gothenburg will be employed. The AI technology, developed by researchers in the physics department, allows for the monitoring of multiple micromotors simultaneously under a microscope. This capability is crucial for optimizing the design of the micromotors, as the bubbles produced during operation can obstruct visibility.
One significant breakthrough is the coating of micromotors with laccase, a chemical compound that accelerates the conversion of urea into ammonia. The conversion of urea to ammonia is not only beneficial for wastewater treatment but also offers the potential for renewable energy. Extracting ammonia from water provides a source of green energy, as ammonia can be further converted into hydrogen.
Despite the promising advancements, there are challenges in fine-tuning the micromotors for optimal water purification. The AI method plays a crucial role in monitoring the micromotors’ movements and functionality, especially in a laboratory setting where development work is ongoing. However, researchers acknowledge the need for further modifications to the AI method to facilitate its application in large-scale trials.
The ultimate goal is to transform urban water treatment plants into energy producers by perfecting the design and functionality of these micromotors. The timeline for achieving this objective remains uncertain, as substantial development work, including modifications to the AI method, is still required for successful implementation in real-world scenarios.
