Abstract: A stepped surface relief structure positioned on a substrate is configured to reflect narrow-band light wavelengths and is further configured such that the substrate can be incorporated into at least one of a thread, a fiber or a flake.

Abstract: A diffuser is disclosed which transmits or reflects incident light into a specific range of angles. In a preferred embodiment, this light is uniformly scattered throughout a cone of angles. The diffuser consists of two parts. The first part diffracts or reflects light into a specific offset angle. The second part, in the preferred embodiment, uniformly scatters the light through a range of angles, which is centered on the offset angle. The diffusers have utility in applications such as screens for wrist watches, computers, calculators, and cell phones.

Abstract: Transition metal complexes, referred to hereinafter as “metalloligands”, that catalyze the degradation of DNA and the cleavage of RNA at select sites are provided. In one embodiment, the metalloligand has the following structure: wherein R1 is an amino group, i.e. an NH, or an alkylamino group comprising 1 or 2 carbon atoms; wherein R2 is selected from the group consisting of an amino group, a hydroxyl group, i.e., O(H), an alkylamino group comprising 1 or 2 carbon atoms; and an alkylhydroxyl group comprising 1 or 2 carbon atoms; wherein J is a ligand which comprises at least one carbon-containing five-membered or six-membered ring structure; and wherein M is a transition metal ion which is bound via coordinate bonds to R1 and R2.

Abstract: A ventilated transportable freight container is disclosed. The container is ventilated by natural convection through at least one lower side vent comprising a lower plenum chamber for distributing air into the container and restricting entry of moisture in the form of rain, sleet or snow into the container and at least one upper top vent, including a plenum chamber. The upper top vent or vents may be formed in the sidewall of the enclosure or in the roof of the enclosure depending upon the structure of the container and the particular application. The use of one or more upper top vents enhances circulation of air by natural convection. The invention also incorporates sidewall and endwall spacers extending from the sidewalls and endwalls into the enclosure to provide passageways for the circulation of air to ventilate the enclosure and a path for condensation drainage. In one embodiment of the invention, the transportable freight container of present invention comprises a rail freight car.
