However, challenges such as urea crystallization, mixing quality, and injector performance can hinder the effectiveness of SCR systems. Recent studies have focused on various aspects of SCR ...

A team of chemists and agriculture specialists has developed a way to transform urea in wastewater, into percarbamide, which can be used as a fertilizer. In their paper published in the journal Nature ...

A cheap and simple electrochemical process has been developed that captures urea – a vital nitrogen-rich ingredient to make ...

This was then put in a concentrated urea-rich solution. When they passed electricity through the solution, solid crystals of percarbamide formed, made from oxygen in the air, hydrogen from water and ...
