  • Patent number: 10809197
    Abstract: Detecting physical forensic evidence on a surface includes contacting the surface with a composition, the composition including a rare-earth metal and a chelator. The composition contacting the surface is illuminated with electromagnetic radiation configured to cause the composition to fluoresce in a pattern indicative of physical forensic evidence. The pattern indicative of physical forensic evidence can then be captured. The composition can be made by combining a rare-earth metal, a chelator, and a solvent to form a solution, precipitating the rare-earth metal and the chelator in the solution, and isolating the precipitate of the rare-earth metal and the chelator from a remainder of the solution. The resulting composition includes a porous metal-organic framework of a rare-earth metal and a chelator, where the pores range in diameter from about 0.01 nm to about 50 nm.

  • Patent number: 10807133
    Abstract: Embodiments relate to instrumentation configuration for emergency response. Initially, instrument profiles are obtained from an instrument data source, where each instrument profile corresponds to an instrument for emergency response. Criteria are applied to each of the instrument profiles to determine performance scores for the instruments. Scenario sensors are used to collect real-time measurements at a geographic location of an emergency. At this stage, scenario parameters comprising the real-time measurements are obtained from a scenario data source. Each instrument profile is evaluated based on the scenario parameters to determine a suitability index. The performance score and the suitability index of each instrument profile is combined to determine an instrument rating. An instrument subset is selected from the instruments based on the instrument ratings.
