Splet12. apr. 2024 · 1. Introduction. Air pollution is a major global health concern. In 2024, The World Health Organization (WHO) estimated that 90% of the global population lived in areas which fail to meet their guideline concentration for ambient fine particulate matter (PM 2.5), an annual average of 10 µg m −3 [].In September 2024, this guideline value was revised … SpletECM is a material removal process that relies on the electrochemical processes to remove materials from difficult-to-cut materials, which are electrically conductive. Complex shapes can be generated in hard materials in this method without causing any tool wear.
