Abstract: Visually undistorted thin film electronic devices are provided. In one embodiment, a method for producing a thin-film electronic device comprises: opening a scribe in a stack of thin film material layers deposited on a substrate to define an active region and an inactive region of the thin-film electronic device, the stack comprising at least one active semiconductor layer. The active region comprises a non-scribed area of the stack and the inactive region comprises a region of the stack where thin film material was removed by the scribe. The method further comprises depositing at least one scribe fill material into a gap opened by the scribe. The scribe fill material has embedded therein one or more coloring elements that alter an optical characteristics spectrum of the inactive region to obtain an optical characteristics spectrum of the active region within a minimum perceptible difference for an industry defined standard observer.

Abstract: A design for wind turbine rotor blades, aircraft wings, and/or other aerodynamic applications which may reduce the vorticity downstream and thus improve lift is described. The blade designs may include an increase in the blade chord towards the tip of the blade, a change in the twist angle at least once along the length of the blade, and/or a change in the thickness of the blade at least once along the length of the blade. These changes individually or in combination may allow for the creation of a counter-rotating vortex behind the blade, increasing power generation and/or lift.

Abstract: Described herein are catalysts and methods for converting waste biogas (e.g., a mixture of carbon dioxide and methane) into useful products. In some embodiments, the biogas is converted into a highly purified methane, that can be further processed to generate fuel products, including recycled natural gas (RNG) and liquid fuels. The described catalysts and methods may be advantageous over conventional methods, including by reducing catalyst costs, decreasing temperature requirements and/or providing higher purity products by reducing carbon dioxide and carbon monoxide in product streams.
