Abstract: Systems and methods for improving the brightness of a transparent display are disclosed herein. One embodiment collects ambient light using an array of diffraction gratings disposed on an external surface of a building; filters the ambient light to produce filtered ambient light; generates primary-source light using a light-emitting-diode (LED) light source; and injects, into a transparent edge-lit liquid crystal waveguide display deployed in at least a portion of a window of the building, the primary-source light and the filtered ambient light in a color-synchronized manner. The filtered ambient light improves the brightness of the transparent edge-lit liquid crystal waveguide display.

Abstract: A method to control the density of a three-dimensional photonic crystal template involves changing the irradiation time from at least four laser beams to yield a periodic percolating matrix of mass and voids free of condensed matter from a photoresist composition. The photoresist composition includes a photoinitiator at a concentration where the dose or irradiation is controlled by the irradiation time and is less than the irradiation time that would convert all photoinitiator to initiating species such that the density of the three-dimensional photonic crystal template differs for different irradiation times. A deposition of reflecting or absorbing particles can be patterned on the surface of the photoresist composition to form a template with varying densities above different areas of the substrate.

Abstract: A cooling assembly includes a housing defining a fluid chamber, wick structures arranged on an interior surface of the fluid chamber such that one or more flow channels are present therebetween, and a divider. The divider includes an outer frame comprising a first side and a second side and one or more bridging supports extending between and connecting the first side and the second side of the outer frame. The one or more bridging supports are aligned with the one or more flow channels between the wick structures. Each one of the one or more bridging supports define a plurality of vapor flow paths extending therethrough. The one or more bridging supports further define a plurality of vapor spaces between the one or more bridging supports that are aligned with the wick structures. The plurality of vapor flow paths are fluidly coupled to the vapor spaces.

Abstract: One or more methods of designing an FC bipolar plate that enhance the operational performance of FC. A first image analysis is conducted of image data of a fluid flow field structure having one or more dehomogenized microstructures to identify channels having a fluid flow blockage at a channel wall dead-end. The channel wall dead-end of each identified channel is selectively removed in a manner that fluidically connects each identified channel to an adjacent channel. Then, a second image analysis of the image data is conducted in response to selectively removing the channel wall dead-ends to measure a length of each channel wall. Channels walls having a length greater than a threshold channel wall length value are selectively cut, thereby providing reduced fluid flow resistance throughout the FC.

Abstract: A method of decomposing a cured aromatic epoxy resin uses a molten salt bath at less than about 350° C. The molten salt bath includes a plurality of alkali metal hydroxides. The cured aromatic epoxy resin can be in intimate physical contact with a metal or alloy. The cured aromatic epoxy resin can be patterned by a lithographic method. The lithographic method can be multibeam interference lithography to form a three-dimensional photonic crystal template on a conductive substrate for electrodeposition of metal. Contacting the three-dimensional photonic crystal template with the electrodeposited metal with the molten salt bath can form a metal matrix device displaying a periodic pattern that is the inverse of the periodic pattern of the decomposed three-dimensional photonic crystal template.

Abstract: A three-dimensional photonic crystal template on a reflective substrate displays a periodic patterned from multibeam interference lithography with constructive volumes of a cured photoresist composition and destructive volumes that are voids free of mass containing defects and where the reflective substrate is conductive. A method to generate the three-dimensional photonic crystal template includes using at least four laser beams of unequal intensity, oriented such that a dose of light controlled by the irradiation time generates the periodic pattern with a small dose, where the light reflected from the substrate is insufficient to activate a threshold quantity of photoinitiator in the destructive volumes for the formation of any anomalous condensed matter in the intended void volume.
