Abstract. An extensive program of experiments focused on biomass burning emissions began with a laboratory phase in which vegetative fuels commonly consumed prescribed fires were collected the southeastern and southwestern US burned series 71 at Forest Service Fire Sciences Laboratory Missoula, Montana. The particulate matter (PM2.5) measured by gravimetric filter sampling subsequent analysis for elemental carbon (EC), organic (OC), 38 elements. trace gas an open-path Fourier transform...
The impact of ship emission reductions can be maximised by considering climate, health and environmental effects simultaneously using solutions fitting into existing marine engines infrastructure. Several options available enable selecting optimum for different ships, routes regions. Carbon-neutral fuels, including low-carbon carbon-negative from biogenic or non-biogenic origin (biomass, waste, renewable hydrogen) could resemble current fuels (diesel-type, methane methanol)....
We report the first joint shipboard and airborne study focused on chemical composition water-uptake behavior of particulate ship emissions. The focuses emissions from main propulsion engine a Post-Panamax class container cruising off central coast California burning heavy fuel oil. Shipboard sampling included micro-orifice uniform deposit impactors (MOUDI) with subsequent off-line analysis, whereas measurements involved number real-time analyzers to characterize plume aerosol, aged few...
Biodiesel is one of the most promising alternative diesel fuels. As emission regulations have become more stringent, particulate filter (DPF) has an essential part aftertreatment system. Knowledge kinetics exhaust particle oxidation for fuels useful in estimating change regeneration behavior a DPF with such This study examines characteristics emissions as well using 1996 John Deere T04045TF250 off-highway engine and 100% soy methyl ester (SME) biodiesel (B100) fuel. Compared to standard D2...
Porous TiO2/C nanocomposite shells with high capacity, excellent cycle stability, and rate performance have been prepared. The synthesis involves coating colloidal TiO2 nanoshells a resorcinol-formaldehyde (RF) layer controllable thickness through sol–gel-like process, calcining the composites at 700 °C in an inert atmosphere to induce crystallization from amorphous anatase simultaneous carbonization RF carbon. cross-linked polymer contributes stability of shell morphology porous nature...
In February 2015, the United States Environmental Protection Agency (EPA) sponsored a workshop in Research Triangle Park, NC, USA to review current state of science one missions, air quality impacts, and health effects associated with exposures ultrafine particles[1].[...].
The nitridation of hollow TiO 2 nanoshells and their layered assembly into electrodes for electrochemical energy storage are reported. nitridated shells prepared by annealing shells, produced initially using a sol–gel process, under an NH 3 environment at different temperatures ranging from 700 to 900 °C, then assembled form robust monolayer film on water surface through quick simple process without any modification the samples. This approach facilitates supercapacitor cell design...
Because vascular endothelial cell inflammation is critical in the development of cardiovascular pathology, we hypothesized that direct exposure human aortic cells (HAECs) to ultrafine particles induces an inflammatory response. To test hypothesis, incubated HAECs for 4 h with different concentrations (0.001–50 μg/ml) CeO2 nanoparticles and subsequently measured mRNA levels three markers intercellular adhesion molecule 1 (ICAM-1), interleukin (IL)-8, monocyte chemotactic protein (MCP-1) using...
Abstract. Particle size distribution from biomass combustion is an important parameter as it affects air quality, climate modelling and health effects. To date, particle distributions reported prior studies vary not only due to difference in fuels but also experimental conditions. This study aims report characteristics of well controlled repeatable lab scale fires for southwestern United States with focus on chaparral. The laboratory at the Department Agriculture-Forest Service's Fire...
Particle emissions from open burning of southwestern (SW) and southeastern (SE) U.S. fuel types during 77 controlled laboratory burns are presented. The fuels include SW vegetation types: ceanothus, chamise/scrub oak, coastal sage scrub, California sagebrush, manzanita, maritime chaparral, masticated mesquite, oak savanna, woodland, as well SE 1 year, 2 year rough, pocosin, chipped understory, understory hardwood, pine litter. burned at higher modified combustion efficiency (MCE) than the...
In urban environments, vehicle exhaust and nonexhaust emissions represent important sources of fine particulate matter with an aerodynamic diameter less than 2.5 μm (PM2.5), which plays a central role in adverse health effects oxidative stress. We collected PM2.5 filter samples from two highway sites (Anaheim Long Beach, CA) site (Irvine, to quantify environmentally persistent free radicals (EPFRs) contained the generation radical forms reactive oxygen species (ROS) water using electron...
Abstract Because it is important to develop new sustainable sources of edible protein, insects have been recommended as a protein source. This study applied Life Cycle Assessment (LCA) investigate the environmental impact small-scale insect production unit in South Korea. IMPACT 2002 + was baseline assessment (IA) methodology. The CML-IA baseline, EDIP 2003, EDP 2013, ILCD 2011 Midpoint, and ReCiPe midpoint IA methodologies were also used for LCIA methodology sensitivity analysis. fat...
As global demands for rare-earth elements (REEs) continue to grow, the biological recovery of REEs has been explored as a promising strategy, driven by potential economic and environmental benefits. It is known that calcium-binding domains, including helix-loop-helix EF hands repeats-in-toxin (RTX) can bind lanthanide ions due their similar ionic radii coordination preference calcium. Recently, lanmodulin protein from Methylorubrum extorquens was reported, which evolved high affinity over...
