Abstract: A laminar structure upon a substrate is formed from a) a lattice layer comprising DNA (deoxyribonucleic acid) segments arranged to form cells of the lattice layer, and b), at least one nanoparticle being disposed within each cell of the lattice layer. The nanoparticles are preferably of substantially uniform diameter not exceeding 50 nanometers. A coating may be applied to adhere the particles to the substrate and to maintain their substantially uniform spaced-apart relationship. The DNA lattice layer is fabricated using known automated synthetis methods, and is designed to contain specific nucleotide base sequences which cause the DNA to form an ordered array of openings, or lattice cells, by self-assembly. Self-assembly of the DNA lattice may be at an air-liquid interface, or in solution. A preferred embodiment is a magnetic storage medium in which the particles are magnetic particles with diameters in the range of 5-20 nm.

Abstract: An improved composite structural member comprising a complex profile structural member, made of a composite comprising a polypropylene polymer and a wood fiber. The material is useful in conventional construction applications. The complex profile, in the form of an extruded thermoplastic composite member can be used in residential and commercial structures as described. Preferably, the structural member is used in the manufacture of the fenestration components such as windows and doors. Such linear members are designed with specifically configured cross-sectional shapes to form structural elements in the fenestration units. Structural elements must possess sufficient strength, thermal stability and weatherability to permit the manufacture of a structurally sound window unit that can be easily installed into a rough opening but can maintain its attractive appearance and structural integrity over the life of the window unit often twenty years or more.
