| During this project period we focused predominantly on explicit-atom MD simulations and first principles DFT calculations. This involved the force field parameterization for new molecules, i.e., cyclopentene, and the exploration of various DFT codes to identify the one most suitable for our purpose. We conducted several proof of concept studies, concentrating on the structural developments in the immediate vicinity of the surface with which the polymer comes into contact. These ... |

| Polymer dielectric films fabricated by plasma enhanced chemical vapor deposition (PECVD) have unique properties due to their dense crosslinked bulk structure. These spatially uniform films exhibit good adhesion to a variety of substrates, excellent chemical inertness, high thermal resistance, and are formed from an inexpensive, solvent-free, room temperature process. In this work, we studied the dielectric properties of plasma polymerized (PP) carbon-based polymer thin films prepared from two precursors, benzene ... |

| Passive badge monitors for benzene, toluene, and xylene detection (cumulatively) were tested for analyte-specific air analysis onboard U.S. Navy (USN) nuclear submarines. Long-term sampling efficiency was evaluated for a 28-day period by comparing the response of the passive badge to an active tube sampling method. The badges and tubes were exposed to benzene, toluene, and xylene vapors at concentrations ranging from 0.33 to 1.98 ppm, resulting in time-weighted-average exposures ranging ... |

| Monitored natural attenuation (MNA) is a cost-effective remediation approach that is applicable to many sites and embraced by the U.S. Department of Defense (DoD). MNA can be used to mitigate petroleum hydrocarbon, chlorinated hydrocarbon, and metal-contaminated sites as an alternative to groundwater pump-and-treat methods. Determining MNA's technical applicability for a given site is based on sampling and analysis, data evaluation and modeling, and long-term monitoring. Parameters that are evaluated include ... |

| Determination of the adsorption properties of novel activated carbons is important to develop new air quality control technologies that can solve air quality problems in a more environmentally sustainable manner. Equilibrium adsorption capacities and heats of adsorption are important parameters for process analysis and design. Experimental adsorption isotherms were thus obtained for relevant organic vapors with activated carbon fiber cloth (ACFC) and coal-derived activated carbon adsorbents (CDAC). The Dubinin-Astakhov (DA) ... |

| This technical memorandum summarizes the five-year results of natural attenuation treatability studies at 42 Air Force sites contaminated with fuel hydrocarbons. The main emphasis of the work described in this report was to evaluate the potential for naturally occurring degradation mechanisms to reduce dissolved benzene, ethylbenzene, toluene, and xylenes concentrations in groundwater to levels that are protective of human health and the environment. natural attenuation, |

| This report presents the results of a treatability study (TS) performed by Parsons Engineering Science, Inc. (Parsons ES) in the vicinity of Site FT0l at King Salmon Airport in King Salmon, Alaska to evaluate the use of intrinsic remediation with long-term monitoring (LTM) as a remedial option for dissolved benzene, toluene, ethylbenzene, and xylene (BTEX) contamination in the shallow groundwater. Soil and groundwater contamination in the ... |

| This report presents the results of a treatability study for remediation by natural attenuation (RNA TS), completed by Parsons Engineering Science, Inc. (Parsons ES) at IRP Site SS-04, Langley Air Force Base (AFB), Virginia. The TS evaluates the use of natural attenuation with long-term monitoring (LTM) as a remedial option for dissolved hydrocarbon fuel constituents in groundwater. The occurrence of groundwater and soil ... |
