Systems and methods are provided for separating seed from wet material. The method includes aerating raw, wet material comprising seed to provide an aerated material and aspirating the aerated material. The aspirating separates seed from liftings of the aerated material, and the separated seed can then be recovered.

A nanoparticle cluster reduction method yields a new composition of matter including a large percentage (e.g., 75% or higher percentage) of primary nanoparticles in the new composition of matter. The particle reduction method reduces the size of nanoparticle clusters in material of the new composition of matter, allows particle reduction of specific nanoparticle cluster sizes, and allows particle reduction to primary nanoparticles. This new composition of matter can include a high permittivity and high resistivity dielectric compound. This new composition of matter, according to certain examples, has high permittivity, high resistivity, and low leakage current. In certain examples, the new composition of matter constitutes a dielectric energy storage device that is a battery with very high energy density, high operating voltage per cell, and an extended battery life cycle. An example method can include a controlled gas evolution reaction to reduce the size of nanoparticle clusters.

A rock cleaning device for dislodging and cleaning landscaping materials, such as landscape rock includes a vacuum assembly and a suction head. The vacuum assembly generates an airflow through a tube thereof. The suction head is engaged to the tube distal from the vacuum assembly so that an interior space, which is defined by the suction head, is in fluidic communication with the tube. The suction head has an opening positioned in a bottom thereof. A set of nozzles is coupled to a top of the suction head and is engageable a hose, which extends from a source of pressurized air. The nozzles direct pressurized air from the hose through the interior space to dislodge objects, such as landscape rock embedded in a surface, and to clean the objects that now are entrained in the airflow.
