Latest Patents

One of Bryan's latest patents is for tunable negative coefficient thermal expansion materials and composites. This invention involves variable composition ceramics, specifically ZrHfWPO and HfWPO, which exhibit significant negative thermal expansion that remains linear over a wide temperature range, reaching up to at least 900°C. These ceramic material particles can be combined with polymers to create composites suitable for backsheets in photovoltaic modules, among other applications. The thermal expansion coefficient of these composites can be tailored to align with that of solar cells, thereby minimizing stress caused by daily thermal cycling.

Another significant patent is a system and method for thermopile energy harvesting for subsurface well bore sensors. This innovative system includes a tubular pipe inserted into a subsurface borehole, with a borehole casing coaxially arranged around it. An annular space between the casing and the tubular pipe houses a power source that harnesses thermal energy to power a sensor, utilizing the temperature gradient between the casing and the pipe. The method involves attaching thermopiles to the borehole casing or tubing, inducing a thermal gradient, and generating electrical energy to monitor vertical expansion of a CO plume.
