Leverage the Advantages of Aluminum Nitride for Superior Ultra-Wide Bandgap Semiconductors for High-Power, High-Temperature Diodes and Transistors	Metal modulated epitaxy method enables the production of p-type beryllium-doped aluminum nitride films as key components in ultra-wide bandgap semiconductors for the first time. Achieves high reverse breakdown voltage—a significant advantage over wide bandgap materials such as silicon carbide and gallium nitride. Improves current conduction over best previous results in p-type aluminum nitride (AIN) by 30,000,000 times and n-type AlN by 6,000 times.	8666
Tunable Membrane-Based Wastewater Treatment and Resource Recovery	Customizable membrane structure and surface properties provide selective removal of contaminants of emerging concerns (CEC) and recovery of valuable components. An enlarged membrane surface area, combined with a gutter effect from the interlayer, results in nearly double the water permeability of current filtration membranes.

Superluminescent Light Projection (SLP) System Decreases Nanoscale Printing Costs by 10–50 Times	This superluminescent light projection (SLP) system decreases overall nanoscale printing costs by 10–50 times. A parallel writing mechanism supports higher throughput speeds: up to 100 times higher than existing metal printing methods and four times higher than existing polymer printing methods. SLP creates sharp-edged images with minimal speckling patterns, resulting in high-resolution images and structures on both polymer and metal-based films.	9066
Chemically Modified Reduced Graphene Oxides (rGOs) Improve Strength and Qualities of Polymer Composites	Chemically modifying rGO creates improved dispersibility and miscibility that can be used in polymer processes as a composite reinforcement or coating material. Easily scalable solution chemistry and purification/filtration makes the process economically feasible, resulting in a commercially viable material for many applications. Melt lamination results in a robust conductive coating that is more durable than comparable polymer-based coatings and enables many electronically active device designs.	8297
Anodically Coloring Molecular Electrochromics (EC) Improve Contrast, Color, and Transitions	True black-to-clear transitions with high contrast and color tuning are now possible with anodically coloring electrochromics. Broad absorption supports color mixing and color tunability in the charged state, and color tuning is enabled by manipulating the oscillator strengths of radical cation transitions. Energy required for practical electrochromic applications is effectively decreased by much lower oxidative potentials, as compared to their corresponding polyamides.	7745
