A flowerpot and method of manufacture of a flowerpot. The flowerpot includes an outer peripheral surface covered with a grid of tiles.

Epitaxial formation support structures and associated methods of manufacturing epitaxial formation support structures and solid state lighting devices are disclosed herein. In several embodiments, a method of manufacturing an epitaxial formation support substrate can include forming an uncured support substrate that has a first side, a second side opposite the first side, and coefficient of thermal expansion substantially similar to N-type gallium nitride. The method can further include positioning the first side of the uncured support substrate on a first surface of a first reference plate and positioning a second surface of a second reference plate on the second side to form a stack. The first and second surfaces can include uniformly flat portions. The method can also include firing the stack to sinter the uncured support substrate. At least side of the support substrate can form a planar surface that is substantially uniformly flat.

The present invention relates to a highly new method of magnet-based cold molding to make magnetic composite structure. According to the process of this invention, the magnetic composite structure can be efficiently made into molded products with great magnetic and physical strength. This method can greatly reduce the cost and lead time of making the magnetic composite structure. It also reduces the impact on environment since the magnet-based cold molding differs from other traditional method such as the plastic-molding or casting mold, which destroys the magnetism of the magnets and pollutes the environment.

A building panel structure and a process for manufacturing the structure are disclosed. The structure comprises a concrete layer disposed on the outside of a building, an insulating material comprising polyurethane in the center of the structure and a corrugated steel layer on the inside of the building. A steel plate overlays the top of the panel and a lip member attached to the plate and perpendicular to it covers a portion of the corrugated steel layer exposed surface. U-shaped loops are welded to the plate and embedded in the concrete to provide structural integrity and shear resistance to the structure. The process of manufacturing the building structure comprises positioning the plate, lip and loop assembly in a container, setting the concrete on the bottom of the container over the loops and forming the polyurethane layer between the concrete and corrugated steel layers by an in-situ chemical reaction.

In a process for manufacturing molded ceramic composite materials, a preform of a ceramic composite material is provided in which ceramic particles having a platelet configuration are formed within a ceramic matrix. The preform is thermoformed within a mold by heating to a temperature greater than a melting or softening temperature of the ceramic matrix and applying a load to deform the preform to form the molded ceramic composite material in a desired configuration. The process is used to fabricate precisely molded ceramic composite materials and devices containing them. The materials and devices can be used for thermal management, such as for electronic components and other heat generating structures.
