Fabrication process for creating functional nanostructures on sapphire and other hard optical ceramics
Background Achieving precise high-aspect-ratio nanostructures on hard optical materials presents significant technical hurdles due to the intrinsic properties of these substrates, such as sapphire’s high hardness, chemical stability, and thermal tolerance. Traditional fabrication methods often struggle with generating uniformly patterned, tall,...

Infinite-dimensional integrated digital image correlation (IDIC)
Background Digital image correlation (DIC) methods are common in laboratory experi­ments. Often termed two-dimensional digital image correlation (2D-DIC), the method uses a camera to acquire images of a planar object that is deforming nominally within the specimen surface plane that is being imaged. DIC algorithms typically perform the image registration...

Rare earth metal extraction from ash
Background Rare earth elements (REEs), such as lanthanides, yttrium, and scandium, are critical components in numerous advanced technologies, including electronics, energy storage systems, and medicine. Currently, the majority of REEs are sourced from a limited number of mining operations, which poses substantial risks to geopolitical tensions, supply...

Negative enthalpy collector coatings to enhance stability of metal anodes
Problem Anodeless or anode-free liquid, solid and hybrid liquid-solid batteries hold tremendous promise, offering lower cost in parallel to over 50% higher energy by weight and by volume. However, because of the poor Coulombic efficiency (CE)—which leads to poor cathode utilization, rapid capacity fade during cycling, an unstable solid electrolyte...

Functionalized kapok fiber filter for oil and bacteria removal
Problem statement Contaminated water from the produced water industry must be treated prior to discharge, reuse, or recycling. Advanced treatment is often necessary to meet increasingly strict regulations, leading to membrane filtration use in produced water treatment. These membranes are susceptible to different forms of fouling, especially when organics...

Synchronous ripple filter for switch-mode systems
Problem statement Switch-mode systems such as power converters usually generate significant electromagnetic interference (EMI) in the form of high-frequency current at their input (e.g., the grid) and/or output (e.g., processor supply voltages), which must be filtered to meet product specifications and/or regulations. This is typically accomplished...
