Biochar can benefit human society as a carbon-negative material and soil amendment. However, negative biochar impacts on plant germination growth have been observed, they not fully explained. Therefore, protocols to avoid these risks cannot be proposed. We hypothesized that the free radicals generated during charring may inhibit growth. Significant electron paramagnetic resonance (EPR) signals were observed in biochars derived from several types of common biomass (corn stalk, rice, wheat...
Generation of environmentally persistent free radicals (EPFRs) on solid particles has recently attracted increasing research interest. EPFRs potentially have high reactivity and toxicity. However, the impact organic contaminant behavior is unclear. We hypothesized that in biochars can degrade contaminants play an important role behavior. observed obvious degradation p-nitrophenol (PNP) presence biochars, through detection NO3(-) as well byproducts. The extent PNP was correlated to intensity...
The mining and burning of low-rank coal in Xuanwei, China have attracted a great deal research attention because the generated polyaromatic hydrocarbons (PAHs) high incidence lung cancer this region. Given abundant transition metals allitic soil, we hypothesized that environmentally persistent free radicals (EPFRs) are formed region potential risk had not been addressed. Strong electron paramagnetic resonance (EPR) signals 3.20 × 1017 – 3.10 1019 spins/g were detected environmental samples,...
Persistent free radicals (PFRs) in biochar can influence reactivity, promoting organic contaminant degradation or even causing certain toxic impacts. However, the PFR generation mechanism is not still well understood. An investigation of relationship between formation and chemical structure essential for understanding mechanism. Our situ measurement results showed that intensities increased from 0–509.5 to 146–5678 a.u. after being pyrolyzed at 300 °C 60 min. The significant positive...
Although dissolved organic matter (DOM) could effectively disperse carbon nanotubes (CNTs), sorption characteristics of DOM-suspended CNTs are unclear. In this study, we evaluated the relative contribution to overall from humic acid (DHA) coating (decreased sorption) and CNT dispersion (increased sorption). We observed that coefficients sulfamethoxazole (SMX) on DHA-suspended were up 2 orders magnitude higher than aggregated CNTs. mass percent suspended low (generally less 1%), their...
Carbon nanotubes (CNTs) are hydrophobic in nature and thus tend to accumulate sediments if released into aquatic environments. As part of our overall effort examine the toxicity carbon-based nanomaterials sediment-dwelling invertebrates, we have evaluated different types CNTs 14-d water-only exposures an amphipod (Hyalella azteca), a midge (Chironomus dilutus), oligochaete (Lumbriculus variegatus), mussel (Villosa iris) advance conducting whole-sediment tests with CNTs. The results these...
The performance variation and its associated factors of a polymer composites over wide temperature range need to be particularly concerned in engineering application. In this article, on the basis molecular dynamics simulation analysis experimental verification glass transition ( T g ) neat epoxy resins single‐walled carbon nanotube (SWCNT)/epoxy with two structures aromatic diamines curing agents, elastic modulus systems were studied from cryogenic (100 K) until near depth. Both results...
Environmentally persistent free radicals (EPFRs) can induce reactive oxygen species, causing adverse health impacts, and residential fuel (biomass coal) combustion is believed to be an important emission source for EPFRs; however, the characteristics of EPFRs are rarely studied in real world. Here, we conducted a field campaign evaluating presence generated from biomass coal burning rural China. The factors (EFs) (with units 1020 spins·kg-1) PM2.5 crop residues (3.97 ± 0.47) were...
X-ray imaging has been developed with widespread industrial applications, from medical diagnostics, security, and inspection all the way to space exploration. Accordingly, enthusiasm for extensive research on scintillators steadily growing. However, obtaining superior performance via feasible processing minimizing scattering of propagation between scintillator screen object, especially targets highly curved surfaces, are still challenges. Here, an organic metal halide [Bmmim]2SbCl5 (Bmmim =...
The formation and occurrence of environmentally persistent free radicals (EPFRs) have recently attracted increasing research attention. interactions between organics transition metals the crystalline forms are essential for EPFR formation. This study is thus designed to investigate catechol degradation compare characteristics EPFRs on α-Fe2O3 (hematite, HM) α-FeOOH (goethite, GT). Catechol was inhibited in dark presence iron oxides. inhibition stronger GT-silica, but electron paramagnetic...
