Abstract: A two-step process is provided for forming large photonic single crystals of about 0.1 millimeter and greater via DNA coated colloidal particles. The two-step process generally include decoupling the nucleation and growth steps. In particular, DNA colloidal particles are partitioned in nanoliter droplets formed in a water in oil emulsion using microfluidics. Once a crystal nucleates within a droplet, depletion of particles occurs as the crystal grows inhibit formation of more crystals within the droplet. A small number of droplets containing these seed crystals are then mixed with droplets containing weak DNA coated colloidal particles. The emulsion is then broken and heated at a temperature effective to cause dissociation of the weak particles while the seeds remain stable. The system is further cooled at a temperature effective that the particles stably adhere to the seed crystals resulting in growth while inhibiting nucleation of new crystals.

Abstract: In an aspect an apparatus for geometric part searching is presented. An apparatus includes at least a processor and a memory communicatively connected to the at least a processor. At least a processor is configured to generate a search index as a function of a plurality of part specification files. At least a processor is configured to receive an input part specification file. At least a processor is configured to generate a query for an input part as a function of an input part specification file and a search index. A query is configured to output a comparison of an input part specification file to a part estimation specification file. At least a processor is configured to identify a matching part estimation file from a plurality of query results.

Abstract: An inner liner for glass-reinforced plastic pipes comprising a nonwoven fabric bonded to each side of a plastic film. In the manufacture of pipe, the composition is saturated with the plastic resin, e.g., polyester resin, and wound onto the pipe mandrel. The resin-glass body of the pipe is then wound over the liner and the entire composition cured.The liner prevents damage to the pipe as a result of corrosive material, e.g., mineral acids.
