Vacancies, especially anion vacancies within the three-dimensional structure of catalysts, function as active sites. These active sites are energetically involved in the process of catalysis. However, anion vacancies alone are not effective without the presence of transition metal sites. This…
To demonstrate the method in practice, the team applied it to urease inhibitors tested in vitro. N-(n-butyl) thiophosphoric triamide, widely known as NBPT, and acetohydroxamic acid (AHA) produced strong inhibition of urea hydrolysis, reducing ammonium formation by up to 73–77% after…
Covalent organic frameworks could help capture and break down nitrate pollution from waterways that causes algal blooms Covalent organic frameworks (COFs) can be used to rearrange water molecules, increasing the efficiency of the reduction of nitrate to ammonia, researchers in…
A laboratory study found that sodium acetate- and sodium 2-ethylhexyl sulfate-modified natural zeolite removed more than 90% of ammonia nitrogen under optimal conditions, primarily through sodium–ammonium ion exchange. The researchers prepared SS@PNZ and evaluated its adsorption and recovery performance…
Researchers have built a ruthenium catalyst anchored to iron-nitrogen-carbon sites that synthesizes ammonia at 400 degrees Celsius and 1 megapascal while resisting sintering and hydrogen poisoning.

The collaboration brings together ABS, HD KSOE and Siemens. The US, South Korea and Germany have recently joined forces in order to develop a new digital twin technology that could predict how toxic ammonia leaks spread aboard ships. The American…
Classification society ABS, HD Korea Shipbuilding & Offshore Engineering (HD KSOE) and engineering firm Siemens have agreed to develop digital twin technology to assess ammonia leak risks on ships. IMAGE: Ship-to-ship ammonia bunkering of an ammonia-capable gas carrier in Japan. NYK…
ABS, HD Korea Shipbuilding & Offshore Engineering (HD KSOE) and Siemens have signed a memorandum of understanding (MOU) to collaborate on digital twin technology for assessing the safety of ammonia-fuelled vessels. Announced at Gastech 2026 (pictured), the MOU aims to combine computational…
