The nanobubbles are nanoscopic cavities, typically contained in aqueous solutions and filled with gas to an internal equilibrium pressure, at least equal to that of the external environment. The nanobubbles have the ability to change the normal characteristics of the solution. They are stable for long periods of time in contrast with larger or smaller bubbles that disappear shortly. Because of the theoretically very high pressure within nanobubbles (small size and high surface tension), the gas should be leaving the nanobubbles within microseconds. Under specific conditions, nanobubbles can be formed freely and remain stable for long periods of time, up to several months.
The characteristics of nanobubbles differentiate the physical and chemical properties of a product, creating new opportunities for profitable new products and applications.
The nanobubbles are going to be used for plant nutrition through the development of new fertilizers, using methods of Nanotechnology, in which all the nutrients are bioactive and readily digestible by all parts of the plant, without any retention or loss of nutrients.
In this way, significant amounts of lubricating components will be saved, having as a result the reduction of the specific consumption of fertilizers and, consequently, the reduction of their overall imprints.
Furthermore, the addition of nutrients enriched with nanobubbles to the soil, gives the possibility of an integrated nutrition, accompanied by a controlled release of nutrients, while smaller amounts of those are used and fertilizer losses throughout soil ground and ground water are by far lower.
