This study used several real-time and filter-based aerosol instruments to measure PM2.5 levels in a high-rise residential green building the Northeastern US compared performance of those instruments. 24-hr average concentrations were determined using Personal Modular Impactor (PMI) with 2.5 µm cut (SKC Inc., Eighty Four, PA) direct reading pDR-1500 (Thermo Scientific, Franklin, MA) as well its filter. 1-hr measured same apartments an Aerotrak Optical Particle Counter (OPC) (model 8220, TSI,...
Individuals with COVID-19 who do not require hospitalization are instructed to self-isolate in their residences. Due high secondary infection rates household members, there is a need understand airborne transmission of SARS-CoV-2 within We report the first naturalistic intervention study suggesting reduction such risk using portable air cleaners (PACs) HEPA filters. Seventeen individuals newly diagnosed completed this single-blind, crossover, randomized study. Total and size-fractionated...
Fuel additives incorporating nanosized ceria have been increasingly used in diesel engines as combustion promoters. However, few studies assessed the impact of these nanotechnology-based on pollutant emissions. Here, we systematically compare emission rates particulate and gaseous pollutants from a single-cylinder, four-cycle engine using fuel mixes containing nanoceria varying concentrations. The test fuels were made by adding different amounts commercial additive Envirox into an...
Wildfire particulate matter from Canadian forest fires significantly impacted the air quality in northeastern United States during summer of 2023. Here, we used real-time and time-integrated instrumentation to characterize physicochemical properties radiative effects wildfire reaching metropolitan areas New Jersey/ York this extreme incident. The forcing -352.4 W/m2 derived here based on measured optical explains, some extent, ground level temperature reduction about 3 °C observed City Such...
The global increase in wildfires, primarily driven by climate change, significantly affects air quality and health. Wildfire-emitted particulate matter (WFPM) is linked to adverse health effects, yet the toxicological mechanisms are not fully understood given its physicochemical complexity lack of spatiotemporal exposure data. This study focuses on characterization WFPM from a Canadian wildfire June 2023, which affected over 100 million people US Northeast, particularly around New Jersey/New...
There are limited data on air quality parameters, including airborne particulate matter (PM) in residential green buildings, which increasing prevalence. Exposure to PM is associated with cardiovascular and pulmonary diseases, since Americans spend almost 90% of their time indoors, exposures may substantially contribute overall exposure. Our objectives were to: (1) measure various fractions longitudinally apartments multi-family buildings natural (Building E) mechanical L) ventilation; (2)...
Bioaerosol concentrations in residential buildings located the Northeastern US have not been widely studied. Here, 2011-2015, we studied presence and seasonal variability of culturable fungi bacteria three multi-family apartment correlated bioaerosol with building ventilation system types environmental parameters. A total 409 indoor 86 outdoor samples were taken. Eighty-five percent investigated apartments had indoor-outdoor (I/O) ratios below 1, suggesting minimal sources fungi. In...
The Fermi level position in low temperature (LT) GaAs has been studied by photoreflectance (PR). By etching the LT-GaAs to a different thickness, we find as-grown as well annealed is firmly pinned. pinning position, however, occurs at energies: 0.47 eV below conduction band edge for samples and 0.65 samples. believed be result of high degree charge compensation deep levels, while due depletion carriers Schottky barrier metallic As precipitates. From measured ionization ratio antisites, (0/+)...
Room-temperature photoluminescence is used to investigate the basic recombination mechanisms in carbon-doped GaAs samples, with hole concentrations ranging from 3.0×1016 1.2×1020 cm−3. The solution of a one-dimensional, steady-state continuity equation for minority carriers indicates that heavily GaAs, surface minimal, while bulk nonradiative dominant. rate depends not only on p2, which represents Auger recombination, but also p3. By using single p+-GaAs:C (1×1020 cm−3) base layer an...
Exposure to bioaerosols has been implicated in adverse respiratory symptoms, infectious diseases, and bioterrorism. Although these particles have measured within residential occupational settings multiple studies, the deposition of bioaerosol human system only minimally explored. This paper uses real-world environmental measurement data total fungal spores using Air-o-Cell cassettes 16 different apartments residents' physiological those predict spores. The airborne spore concentrations were...
Portable air cleaners (PACs) equipped with HEPA filters are gaining attention as cost-effective means of decreasing indoor particulate matter (PM) pollutants and airborne viruses. However, the performance PACs in naturalistic settings spaces beyond room containing PAC is not well characterized. We conducted a single-blinded randomized cross-over interventional study between November 2020 May 2021 homes adults who tested positive for COVID-19. The intervention was filtration operated filter...
The use of thick nonporous Au/Cr electrodes which can lead to a change in the sweeping mechanism is discussed. With these electrodes, color-center front advances from anode cathode quartz that swept air at temperatures below alpha - beta transition. Evidence presented indicates that: (1) color centers form beneath portions correlate with formation interface Cr-oxides and silicides; (2) clear striae are created along C-axis where either do not or subsequently bleached cylindrical volumes...
Abstract Carbon Capture, Utilization, and Storage (CCS) technology is one of the most relevant technologies aimed at reducing GHG emissions. It vital for energy sector industry, especially hard-to-abate industries, to decarbonize them. When CO2 utilized, instead stored, overall known as CCUS, where "U" stands utilization; although market utilization small compared produced amount CO2, it adds an attractive alternative storage, allows introduce new or improved products into market. To assess...
Vehicular emissions are a major culprit in the rise of urban air pollution. The particulate matter (PM) emitted from vehicular sources includes primarily ultrafine particles (UFPs) with aerodynamic diameters less than 0.1 µm (PM
