Abstract: A structural reinforcement system that utilizes a lath for receiving cementitious material. Lath is affixed to support structure such as sheathing supported by studs as may commonly be found in building construction. Strip members are affixed to the lath and function as fastener guides. Fasteners penetrate the strips for affixing lath and strips to the support structure. The strips are made of a compressible material that protects the lath from damage due to impacts associated with installing the fasteners and forms a gasket-like seal around the fasteners. Strips may be used as drainage guides for directing water that may flow behind the lath. The width of the strips creates spacing between the lath and the support structure, which allows for controlling of a thickness of a base layer of cementitious material by selecting a desired width. In another embodiment, entangled filaments are used as lath material for receiving cementitious material.

Once the sample is uniformly heated such that the entire sample block has a sufficiently low process viscosity it may be shaped into high quality amorphous bulk articles via any number of techniques including, for example, injection molding, dynamic forging, stamp forging, sheet forming, and blow molding in a time frame of less than 1 second.

Abstract: Enhanced heat transfer by kinetic movement of boundary layer film by introducing particles with specialized surfaces. A boundary layer is stagnant, reducing heat transfer into a flowing fluid. Boundary layer heat transfer is primarily conduction. The introduction of specialized particles into fluid promotes boundary layer mixing, thereby converting conduction to convection through the film. Particles of the invention tumble while mixing the boundary layer, which provides low surface area energy sites around the particles. Kinetic movement increases nucleation formation for gas phase transfer during boiling. Metal and ceramic nanoparticles in fluids increase fluid thermal conductivity. By modifying surface characteristics of such nanoparticles to promote boundary layer mixing, fluid heat transfer and thermal conductivity will increase.
