UNSW engineers have tackled a longstanding problem at the heart of global agriculture: how to make urea for fertilizer ...

H. B. DIXON has observed that the ignition temperature of hydrogen-oxygen mixtures may be lowered so much as 200° C. by small quantities of nitrogen dioxide. Hinshelwood 1,2 and his co-workers, who ...

A research team has fully characterized a key chemical reaction that affects the formation of pollutants in smoggy air in the world's urban areas. When applied to Los Angeles, the laboratory results ...

The process of pollutant degradation in the troposphere was first understood in the early 1970s 1. It is now widely accepted that the reaction with hydroxyl radicals (OH) is the dominant ...

An ecologically realistic 24-year field study of grasslands showed that elevated levels of carbon dioxide nearly tripled species losses attributed to nitrogen pollution. Dozens of studies have ...

Understanding this chemical reaction, which involves water vapor and nitrogen dioxide, could help reduce the smog that clogs the air in cities from Los Angeles to Beijing, scientists have said. This ...

UNSW Sydney have developed a new approach to producing urea that could transform waste and pollutants into fertiliser.
