Latest Patents

One of Ritchie's latest patents focuses on the "Mechanisms of local stress sensing in multifunctional polymer films using fluorescent tetrapod nanocrystals." This innovative approach utilizes tetrapod quantum dots (tQDs) embedded in block-copolymers to act as sensors for tensile and compressive stress. The research demonstrates that tQDs can detect their own composite dispersion and mechanical properties, showcasing a unique optomechanical response based on the stress applied. The findings indicate that densely-packed tQDs exhibit a blue-shift in photoluminescence under tensile stress, while loosely-packed tQDs show a red-shift. This technology has the potential to enable smart structural nanocomposites that can self-predict impending fractures.

Another significant patent is the "High-temperature strain cell for tomographic imaging." This invention provides systems and methods for high-temperature mechanical testing of materials. The apparatus includes a chamber designed to hold samples while being heated to specific temperatures using heating lamps. The innovative design allows for radiation to interact with the sample, facilitating advanced imaging techniques.
