In the realm of nanotechnology, "nano nitrogen" and "nano urea" represent distinct concepts with specific applications and compositions. Nano nitrogen refers to nanostructures primarily composed of nitrogen atoms, prized for their unique properties such as enhanced reactivity and conductivity. These nanostructures find applications in diverse fields including catalysis, energy storage, and materials science, where their small size and specialized properties offer advantages in various technological advancements. On the other hand, nano urea consists of nanoparticles or nanostructures predominantly made up of urea molecules. This innovation is particularly tailored for agricultural use, aiming to improve the efficiency of urea fertilizers by controlling the release of nitrogen into the soil. By enhancing nutrient uptake by plants and reducing environmental impacts like nitrogen leaching and volatilization, nano urea seeks to optimize agricultural practices for sustainable crop production. Thus, while both nano nitrogen and nano urea share commonalities in their nanoengineering processes, their distinct compositions and targeted applications cater to different scientific and industrial needs.

@Farah Qahtan,

Thank you very much for your detailed information on Nano nitrogen and nano urea. I appreciate your prompt response.

However, my concern was for it's use in agriculture as plant nutrition. Nano nitrogen and nano urea fertilizer in relation to agricultural uses and it's production process.

Further, The size of a nitrogen atom in nanometers is approximately 0.056 nanometers (nm) and the acceptable range of Nano particles is 1 to 100 nm. Thus, nitrogen atom it self nano particle (even the size is more smaller then given lower side size of Nano particles), in this case, can we go for further smaller size of nitrogen atom and can we say it's nano nitrogen?

A nitrogen atom, at approximately 0.056 nm in size, does not qualify as a nanoparticle because nanoparticles are defined as structures ranging from 1 to 100 nm. Nanoparticles exhibit unique properties due to their size, such as increased surface area and quantum effects, which individual atoms like nitrogen do not possess. Therefore, while nitrogen atoms are fundamental building blocks, they do not demonstrate the distinctive nano-scale properties associated with nanoparticles. The term "nano nitrogen" generally refers to larger nano-scale structures containing nitrogen, not individual atoms.

Thank you for your response. So, you mean to say nano nitrogen is not nitrogen in nanoscale, but nanoscale materials containing nitrogen are nano nitrogen? Therefore, some scientists use nano nitrogen and some use nano urea for nanoscale urea.

@Raghad Mouhamad

Thank you for your elaborate answer, but the concern was to go to nano urea or nano nitrogen for the materials of nanoscale urea.
