Abstract: A method of manufacturing a down-conversion substrate for use in a light system includes forming a first crystallography layer including one or more phosphor materials and, optionally, applying at least one activator to the crystallography layer, heating the crystallography layer at high temperature to promote crystal growth in the crystallography layer, and drawing out the crystallography layer and allowing the crystallography layer to cool to form the down-conversion substrate. A light system includes an excitation source for emitting short wavelength primary emissions; and a down-conversion substrate disposed in the path of at least some of the primary emissions from the excitation source to convert at least a portion of the primary emissions into longer-wavelength secondary emissions, wherein the substrate includes one or more crystallography layers, wherein each crystallography layer includes one or more phosphor materials, and optionally at least one activator.

Abstract: The present invention relates to an optical transmitter for transmitting data. The optical transmitter includes a pulse generator for generating N data streams overlapping in time from a de-multiplexed data source. Each respective data stream has pulses with shapes unique to that respective data stream. The transmitter also includes an optical source optically transmitting an output pulse that is generated by summing the uniquely shaped pulses from each respective data stream that are overlapping in time. Each output pulse represents N bits of the data source, where N>1.

Abstract: Catalysts amenable to oxidizing sulfur compounds and systems and methods of using these catalysts to effect the removal of sulfur from crude oil and crude oil distillates are disclosed. The catalyst is disposed with a titanyl moiety which serves to selectively coordinate sulfur compounds and affect their oxidation. The titanyl may be bound within a polymer or on the surface of a polymer or on the surface or in the pores of an inorganic support. The resulting oxidized sulfur compounds are readily separated from the initial crude oil or crude oil distillate streams by traditional separation techniques arrayed as described in the systems and methods disclosed.

The method includes providing a family of phase diagrams for the quaternary melt which shows (i) composition/temperature data, (ii) tie lines connecting equilibrium liquid and solid compositions, and (iii) isotherms representing boundaries of a miscibility gap. Based on the family of phase diagrams, a quaternary melt composition and an alloy growth temperature is selected. A quaternary melt having the selected quaternary melt composition is provided and a ternary or quaternary alloy is grown from the quaternary melt at the selected alloy growth temperature. A method for making homogeneous ternary or quaternary alloy from a ternary or quaternary melt is also disclosed, as are homogeneous quaternary single-crystal alloys which are substantially free from crystal defects and which have the formula AxB1−xCyD1−y, x and y being the same or different and in the range of 0.001 to 0.
