A system for delivering fertilizer to the roots of a plant includes coated fertilizer particles. The coating can include a cellulose derivative, optionally a fatty acid, and a component, such as an aptamer, which binds specifically to a material, such as serine, which is released by the roots of the plant when the plant is actively taking up nutrients from the soil. The permeability of the coating increases when the coated particles are exposed to the material released by the roots of the plant. Thus, nutrient release from the coated fertilizer particles is synchronized with uptake of the nutrients by the plant during active growth. Advantages of the system may include one or more of improved nitrogen use efficiency by the plant, improved crop productivity, and/or reduced leaching of fertilizer from the soil.

Root exudate-activated system for agrochemical delivery

A method and apparatus for controlling the thickness of a thin film or thin layer of discrete particles or of a heterogeneous mixture characterized in that the interfacial tension forces between the solution or suspension and its environment are used as the driving forces to evenly spread the solution, suspension or mixture while the solvent evaporates and/or dilutes.

Method and apparatus for thin film/layer fabrication and deposition

The invention relates to a nanoparticle growing mat (), a method of manufacturing the mat, and a method for the continuous production of organized nanotubes using the mat. The mat () comprising a substrate including carbon, on which is deposited in a predetermined pattern of nanosized catalytic particles whose pattern produces nanotubes in a highly ordered form. The mat () is activated in the presence of a carrier gas, by passing current through the mat () which raises the temperature to the level where, nanotubes are: formed; gathered; withdrawn as nanotube bundles (); and collected.

Continuous production of carbon nanotubes

A method and an apparatus () for making thin layers from particles, wherein the particles are deposited on a carrier fluid flowing by gravity along a ramp () leading to a dam (). The particles are held back at the bottom of the ramp (), thereby causing the particles to be piled up one against the other in a monolayer configuration.
