Nanocrystalline compounds containing essential nutrients have been synthesized to have effective physical and chemical characteristics, including a high contact surface area/total surface area ratio that provides maximal leaf surface contact, limited mobility and improved solubility, a net positive charge, soluble salt-forming groups, and reactive surface edges for cation exchange to release nutrient cationic ions into the water film on leaf surfaces.

The present disclosure relates to a method for preparing salts of bis(fluorosulfonyl)imide and to a method for preparing alkali metal salts of bis(fluorosulfonyl)imide from said bis(fluorosulfonyl)imide salts. More specifically, the invention provides a new method for producing these salts of bis(fluorosulfonyl)imide which is implementable at industrial scale and providing high-purity bis(fluorosulfonyl)imide salts.

The present invention relates to a method of producing hydrogen from ammonia, and in particular a method of producing hydrogen from ammonia by reacting it with a Group I metal, particularly with sodium, for use in a fuel cell and/or in a prime mover. The method may be carried out in-situ in a vehicle. The invention also relates to an apparatus for producing hydrogen from ammonia.
