Abstract: A method for making a catalyst comprises providing an initial compound having a perovskite lattice structure according to formula I M1M2M3O3 ??FORMULA I, where M1 is about 1 relative elemental ratio strontium (Sr); M2 is from greater than 0 to 0.7 relative elemental ratio and is selected from cobalt (Co), scandium (Sc), iron (Fe), nickel (Ni), and titanium (Ti); and M3 is 0.3 to 0.6 relative elemental ratio iridium (Ir). Initial exemplary compounds include SrSc0.5Ir0.5O3 (SSI) and SrCo0.5Ir0.5O3 (SCI). M1 and/or M2 cations are selectively leached from the initial compound to produce a catalyst having substantially increased catalytic performance. Cycling SSI or SCI in an acid produces SSI-H or SCI-H; cycling SSI or SCI in a base produces SSI-OH or SCI-OH. Dual-site metal leaching induced catalytic activity improvement by about 2 orders of magnitude, making reconstructed SrCo0.5Ir0.5O3 among the best-known catalysts for water oxidation in an acidic condition.

Abstract: Described herein is a magnetic dendrometer having a frame, a spring-tension mechanism, and a magnet for moving together with the spring-tension mechanism. A magnetic sensor is attached to the frame. The magnetic sensor senses the linear motion of the magnet. This linear motion translates to trackable fluctuations in magnetic field. The magnetic fluctuations are converted to electrical signals by the magnetic sensor. A spring is attached to a free-floating wishbone-style component. The free-floating wishbone-style component is couped to a slider which has an adjustable, single-contact point with a target (e.g., a vine, a branch, etc.). The frame is a stationary frame that carries the magnetic sensor. The frame connected via the spring to the wishbone/slider combination cooperates with each other for providing linear motion to extend or contract the spring in length directions. The length variations of the dendrometer spring are converted to linear motion of the magnet and then into electronic signals.

Abstract: A machine-learning tool learns from sensors' data of a nuclear reactor at steady state and maps them to controls of the nuclear reactor. The tool learns all given ranges of normal operation and responses for corrective measures. The tool may train another learning tool (or the same tool) that forecasts the behavior of the reactor based on real-time changes (e.g., every 10 seconds). The tool implements an optimization technique for differing half-life materials to be placed in the reactor. The tool maximizes isotope production based on optimal controls of the reactor.

Abstract: A processing workflow centered on machine-learning algorithms that identifies a number of chemical features that can best distinguish the presence or absence of a chemical source. These chemical features are a chemical fingerprint that is unique to each source. The analysis workflow is rapid (e.g., fingerprints can be generated in minutes). The analysis workflow has wide-ranging applications such as detecting markers of pollution sources in rivers and fish tissues, forest pathogen outbreaks, and hard-to-diagnose diseases.
