Each of the outlet tanks is connected with a lower one of the inlet tanks. The strainer unit includes a water outlet port connected with the water inlet pipe, a water inlet port connected with a water feeding pipe, two hollow clamping plates located between the water outlet port and the water inlet port, a filtering sponge clamped between the two clamping plates, a fertilizer ferment chamber located under the water inlet port, and a drain pipe connected with the fertilizer ferment chamber.

Abstract: A fabrication method of a nanomaterial by using a polymeric nanoporous template is disclosed. First, a block copolymer bulk is made from a block copolymer polymerized from decomposable and undecomposable monomers. By removing the decomposable portion of the block copolymer bulk, the polymeric nanoporous template with a plurality of holes is obtained, and these holes have nanostructures with regular arrangement. By exploiting a nanoreactor concept, a sol-gel process or an electrochemical synthesis, for example, is then carried out within the template such that the holes are filled with various filler materials, such as ceramics, metals and polymers, so as to prepare a nanocomposite material having the nanostructure. After removing the polymeric nanoporous template, the nanomaterial with the nanostructure is manufactured.

Abstract: Method for producing metal oxide nanoparticles. The method includes generating an aerosol of solid metallic microparticles, generating plasma with a plasma hot zone at a temperature sufficiently high to vaporize the microparticles into metal vapor, and directing the aerosol into the hot zone of the plasma. The microparticles vaporize in the hot zone into metal vapor. The metal vapor is directed away from the hot zone and into the cooler plasma afterglow where it oxidizes, cools and condenses to form solid metal oxide nanoparticles.

Abstract: Method for producing carbon nanotubes. Carbon nanotubes were prepared using a low power, atmospheric pressure, microwave-generated plasma torch system. After generating carbon monoxide microwave plasma, a flow of carbon monoxide was directed first through a bed of metal particles/glass beads and then along the outer surface of a ceramic tube located in the plasma. As a flow of argon was introduced into the plasma through the ceramic tube, ropes of entangled carbon nanotubes, attached to the surface of the tube, were produced. Of these, longer ropes formed on the surface portion of the tube located in the center of the plasma. Transmission electron micrographs of individual nanotubes revealed that many were single-walled.

Abstract: Spherical and polyhedral particles of boron nitride and method of preparing them. Spherical and polyhedral particles of boron nitride are produced from precursor particles of hexagonal phase boron nitride suspended in an aerosol gas. The aerosol is directed to a microwave plasma torch. The torch generates plasma at atmospheric pressure that includes nitrogen atoms. The presence of nitrogen atoms is critical in allowing boron nitride to melt at atmospheric pressure while avoiding or at least minimizing decomposition. The plasma includes a plasma hot zone, which is a portion of the plasma that has a temperature sufficiently high to melt hexagonal phase boron nitride. In the hot zone, the precursor particles melt to form molten particles that acquire spherical and polyhedral shapes. These molten particles exit the hot zone, cool, and solidify to form solid particles of boron nitride with spherical and polyhedral shapes.

Abstract: A method for generating spherical and irregularly shaped dense particles of ceramic oxides having a controlled particle size and particle size distribution. An aerosol containing precursor particles of oxide ceramics is directed into a plasma. As the particles flow through the hot zone of the plasma, they melt, collide, and join to form larger particles. If these larger particles remain in the hot zone, they continue melting and acquire a spherical shape that is retained after they exit the hot zone, cool down, and solidify. If they exit the hot zone before melting completely, their irregular shape persists and agglomerates are produced. The size and size distribution of the dense product particles can be controlled by adjusting several parameters, the most important in the case of powder precursors appears to be the density of powder in the aerosol stream that enters the plasma hot zone.
