Abstract As one of the most common ferrous (Fe 2+ )-containing oxide minerals in Earth’s crust, ilmenite (FeTiO 3 ) is a potential low-cost heterogeneous Fenton-like catalyst for organic wastewater treatment via catalytic wet peroxide oxidation (CWPO). However, it suffers from low activity and long induction time. Herein anisotropic FeTiO /C nanocomposite with rich Fe ions on large surface area 159.0 m 2 g −1 (surface Fe/Ti /Fe 3+ ratios were respectively 2.1 2.0) was prepared...
Nanocone arrays are promising candidates for broadband light absorption owing to their graded refractive index and multiwavelength resonance mechanisms. However, the bidirectional reflection distribution function (BRDF) wide‐angle performance of plasmonic nanocones remain insufficiently explored. Herein, a gold nanocone array fabricated with ion track method is reported, achieving exceptional absorptivity (>0.98) across wide incidence angle range (5°–75°). Combining finite‐difference...
Abstract Prescribed burning (PB) is one of the most prominent sources PM 2.5 (particulate matter with an aerodynamic diameter less than μm) in southeastern United States. The PB emissions estimates may have significant uncertainty because they are based on burned areas reported to state agencies when burners apply for burn permits. When no permit records available, satellite‐derived products could be used as a substitute tool provide area data. In order evaluate from products, we conducted...
Short-term exposure to fire smoke, especially particulate matter with an aerodynamic diameter less than 2.5 µm (PM2.5), is associated adverse health effects. In order quantify the impact of prescribed burning on human health, a general function was used fields PM2.5 from in Georgia, USA, during burn seasons 2015 2018, generated using data fusion method. A method developed identify days and areas when where had major local air quality explore relationship between acute The results showed...
Magnetic nanostructures with conical shape are highly desired for pursuing extraordinary magnetic properties and microwave absorption. However, the fabrication of such controlled size uniformities alignment is not yet realized. Accordingly, their application as absorber well understood. Here, we report on first demonstration soft nickel nanocone arrays sharp geometry, large aspect ratio, uniform size, parallel alignment. The imaginary part relative complex permeability shows multiband...
Long-term air pollution exposure, notably fine particulate matter, is a global contributor to morbidity and mortality known risk factor for coronary artery disease (CAD) myocardial infarctions (MI). Knowledge of impacts related source-apportioned PM 2.5 limited. New modeling methods allow researchers estimate source-specific long-term on the prevalence CAD MI. The Catheterization Genetics (CATHGEN) cohort consists patients who underwent cardiac catheterization at Duke University Medical...
Sichuan Province, the most industrialized and populated region in southwestern China, has been experiencing severe ozone pollution boreal warm season (April–September). With a surface monitoring network reanalysis dataset, we find that nearly all cities Province showed positive increasing trends warm-season levels. The daily maximum 8-h average (MDA8) levels increased by 2.0 ppb (4.8%) year−1 as whole, with slightly larger some sites such site Zigong (5.2 year−1). Seasonally, monthly level...
Our project examines the association between percent African American and smoke pollution in form of prescribed burn-sourced, fine particulate matter (PM2.5) U.S. state Georgia for 2018. (1) Background: Americans constitute 32.4% Georgia’s population, making it largest racial/ethnic minority group followed by Hispanic at 9.8%. Americans, lower wealth groups are more likely than most middle upper income White to be exposed environmental pollutants. This is true because racial ethnic...
Prescribed burning (PB) is a prominent source of PM2.5 in the southeastern US and exposure to PB smoke health risk. As demand for increases stricter controls are implemented other anthropogenic sources, emissions tend be responsible an increasing fraction concentrations. Here, quantify effect on air quality, low-cost sensors used measure concentrations Southwestern Georgia. The feasibility using as supplemental measurement tool evaluated by comparing them with reference instruments. A...
Prescribed burning (PB) is practiced throughout the USA, most extensively in southeast, for purpose of maintaining and improving ecosystem reducing wildfire risk. However, PB emissions contribute significantly to trace gas particulate matter loads atmosphere. In places where air quality already stressed by other anthropogenic emissions, can lead major health environmental problems. We developed a impact forecasting system facilitate dynamic management modulating activity. our system, new...
