What’s all the fuss about nitrogen in the Netherlands?
NettetHi, I am looking for a safe alternative to Liquid nitrogen that is safe to use in an airtight container (tubes). It doesn't need to be extremely cold but I would like it to have minimal heat loss. What materials should the tubes be made of to ensure the least heat loss. It also shouldn't evaporate. It should always remain below -30 C. NettetInorganic nitrogen pollution in aquatic ecosystems: environmental problems, water quality criteria, and implications of climate change. The major environmental problems related to inorganic nitrogen pollution in aquatic ecosystems are: (1) acidification of lakes and rivers with low or reduced alkalinity; (2) eutrophication of fresh and marine waters (with the … Nettet15. feb. 2024 · Experimental evaluation of nitrogen retention in h-BN, ZrN, and TiN confirmed their resistance to nitrogen loss at 1773 K. However, of these nitrides, TiN is predicted to be the least stable. This work identifies multiple promising materials that are predicted to be effective hydrogen barriers at high temperatures and that are stable at … svq work based assessor
