Abstract: Systems are methods for identifying the composition of non-biological aerosol particles or biological aerosol particles including water bound to the surface of the particles, without pre-treatment using complex organic MALDI matrices. A continuous timing laser may be used to index the aerosol particles, determine optical particle properties, and trigger an IR pulse ionization laser. Ionized fragments, and optionally photons, associated with each particle produced by ionization of the particles the IR ionization laser is analyzed using one or more detectors including a TOFMS detector and an optical detector. Unique mass spectral data and optical data associated with each indexed particle is compiled using data fusion to generate a compiled data set. The compiled optical data is compared with a training data set comprising a knowledge base of known aerosol particles to predict aerosol particle composition.

Abstract: Disclosed are systems are methods for identifying the composition of single aerosol particles, particularly that of bioaerosol particles, without pre-treatment using complex organic MALDI matrices. A continuous timing laser may be used to index aerosol particles, measure particle properties, and trigger a pulse ionization laser. Ionized fragments and optionally photons associated with each particle producing by the ionization laser may be analyzed using one or more detectors including a TOF-MS detector and an optical detector. The laser pulse may comprise a simultaneous IR and UV laser pulse when fragments comprise predominantly of UV chromophores. Unique spectral data associated with each indexed particle from each detector may be compiled using data fusion to generate compiled spectral data. Machine learning methods may be used to improve the prediction of composition over time.

Abstract: Method and apparatus for biomass cultivation (preferably using algae) incorporating photo bio-reactor (PBR) technology coupled with a heat sink to increase energy efficiency. An external PBR array is coupled to an indoor storage tank system with a volume equal to or greater than the volume of the PBR array. A controller can be used to optimize the growth of biomass by optimizing three key growth parameters: exposure to sunlight, temperature and nutrients. The indoor tank system serves as a reservoir where algae can be protected from harsh ambient conditions, minimizing the cost of energy for heating and cooling that would normally be incurred to accommodate ambient temperature swings caused by weather if the biomass is always stored in an outdoor PBR array. During cold winter nights, the biomass can be brought indoors to conserve thermal energy.
