It has recently been shown that the biocatalyst iron nitrogenase not only fixes nitrogen, but also carbon dioxide. However, this nitrogenase form has so far been the least studied. Now two proteins have been identified that are crucial for the energy supply of the enzyme.

Ammonia is perhaps best known as a household cleaner or the chemical that makes your pee smell. Few might realise, however, that half of the world’s food production relies on ammonia-based fertilisers produced in just a handful of countries.  This clear, foul-smelling chemical is largely made by superheating water, air, and natural gas under pressure — a process that emits vast quantities of carbon dioxide. Ammonia synthesis is by far the dirtiest chemical manufacturing process in the world,…

Once you get beyond the early and mid-game crafting options in Enshrouded, the types of materials you will need will only get more difficult to get your hands on. One particularly useful item you will want to craft often is leather, which you will need something called Ammonia Glands to create. Considering leather is necessary for upgrading your inventory space to the highest level, everyone will want to get their hands on it. Being glands, you can probably predict that Ammonia Glands will drop from an enemy, which…

The use of ammonia as a ship fuel could contribute to eutrophication and acidification, due to ammonia leakage and emissions of nitrogen oxides. One of the possible emissions is laughing gas, which is also a greenhouse gas with a much higher warming impact than carbon dioxide.

Researchers at Stockholm University have achieved a breakthrough in studying catalyst surfaces in ammonia production, overcoming previous challenges in the Haber-Bosch process. This advancement, facilitated by a new photoelectron spectroscopy instrument, promises more efficient catalyst materials for a greener chemical industry and a reduction in fossil fuel dependence.The above image illustrates how the catalytic surface reaction provides the foundation for agriculture.

Researchers at the University of Oxford looked at the production costs of ammonia, which are similar to those of very low…

Reversible activation and catalytic transfer of ammonia via a compound of main group elements. Credit: Frank Breher, KIT Researchers at KIT have unveiled a novel system for the activation and catalytic transfer of ammonia – catalysis is based on main group elements. Ammonia (NH3), composed of nitrogen and hydrogen, stands as one of the most commonly manufactured chemicals globally. It plays a crucial role in creating numerous nitrogen-based compounds. If amines could be produced by the simple addition of ammonia to…

Ammonia has been proposed as a clean fuel for ships, airliners, trucks and trains, but China's GAC believes it could also have a future in passenger cars. It's built a combustion engine to test the theory, capable of reducing emissions by around 90%.Ammonia (NH3) carries hydrogen better than hydrogen carries hydrogen, in some regards. It's easier to handle, since it's liquid at ambient temperatures, and it thus doesn't require energy-hungry compression or cryogenic liquefaction gear. You can make it cleanly – although…

Shipping out Companies trying to cut their climate impacts in the marine shipping sector are looking to alternative fuels, including methanol and ammonia. Amogy’s system could be a better option than combustion engines, though, since it would limit pollution that can trap heat in the atmosphere and harm human health and the environment.  I’ll note here that ammonia itself isn’t very pleasant to be around, and in fact it can be toxic. Proponents argue that safety protocols for handling it are pretty well established in…
