“…The average EFs for the total primary phenolic compounds decreased by 56.6% and 24.9% for bituminous and anthracite briquette, respectively, compared to those of bituminous and anthracite chunk. This finding was consistent with the observation reported earlier that the improved fuel produced fewer organic compounds in the combustion than the raw materials did (Růžičková et al., 2021). Notably, this study also reported, for the first time, that EFs for the phenolic compounds in aged samples were also 60.9% and 22.1% lower from bituminous and anthracite briquette than bituminous and anthracite chunk, respectively.…”

Phenolic compounds and aromatic acids, as oxygenated aromatic compounds, can participate in photochemical reactions to form secondary organic aerosols (SOAs), and thus strongly impact climate and human health. In the present study, on‐site combustion experiments were conducted to determine primary emissions and secondary formation of phenolic compounds and aromatic acids released from burning of a variety of solid fuels using a potential aerosol mass‐oxidation flow reactor (PAM‐OFR). Emission factors (EFs) of phenolic compounds and aromatic acids from aged samples were 1.04 to 4.04 and 0.90 to 2.80 times those in the fresh PM2.5, respectively, implying significant amounts of these compounds produced from atmospheric aging processes. Substantially different emission profiles of phenolic compounds were observed between coal and biomass burning, with coal combustion mainly released single‐ring species (82%–86% in primary and 86%–89% in secondary emissions), while biomass burning released more two‐, three‐, and four‐ring species (59%–69% in primary and 50%–58% in secondary emissions). Aromatic acids emission profiles from coal and biomass burning also differed considerably, with biomass burning producing significantly higher (>2 times) abundance of dibasic acids than coal combustion, suggesting higher potential of producing additional ‐COOH group from biomass burning. Benzenediol, cresol, dimethylphenol, 1‐pyrenol, phenanthrenol, and hydroxylbenzonic acid were identified as SOA as they were mainly formed during simulated aging processes. Benzenediol acid/phenanthrenol was much lower from biomass (3.70 ± 1.29) than coal (62.7 ± 9.61), and these values remained stable after aging, suggesting this ratio being suitable as tracer for distinguishing different fuels combustion in source apportionment analysis.

“…Compared to bituminous chunks, the total monocarboxylic and dicarboxylic acid EFs of bituminous briquettes reduced by 43.3% and 64.7%, respectively. The result was similar to a previously reported observation that the modified fuel emitted fewer organic pollutants during combustion than raw fuels . The difference, however, was that the carboxylic acid emission from the anthracite briquette (15.3 ± 2.28 mg kg –1 ) is slightly higher than that of the anthracite chunk (12.3 ± 1.63 mg kg –1 ).…”

This is because the anthracite chunk has a perfect structure, and briquetting destroys the original structure, leading to higher EFs.…”

Carboxylic acids play an important role in atmospheric photochemical reactions, aerosol nuclei, and climate change. Primary and secondary carboxylic acid emissions from various combustion scenarios were quantified. Coal combustion emitted more low-molecular weight (MW) monocarboxylic acids (C29) (15.5−32.3%). Ultrahigh-MW monocarboxylic acid abundance and hexadecanoic acid (C16) versus nonadecanoic acid (C19) remained stable between the primary emission and aging processes, suggesting that they could be ideal markers for source characterization. Significant correlations were observed between the decreasing of toluene and benzene and the increasing of oxalic acid (C2), malonic acid (C3), fumaric acid (C4), suberic acid (C8), azelaic acid (C9), and sebacic acid (C10) (p < 0.05) during coal combustion, suggesting that oxidation of toluene and benzene lead to the formation of dicarboxylic acids during photochemical aging. On the other hand, the oxidation of monocarboxylic acids occurs on carbons farther away from the −COOH group, leading to the formation of dicarboxylic acids. The secondary formation mechanism of dicarboxylic acids from biomass burning differed from that of coal because of the abundance of low-chemical reactivity, ultrahigh-MW monocarboxylic acids; further study is required.

“…6 Both short-and long-term in vivo studies have been carried out with many nanoparticles. 7 There is a growing concern about the use of cuprous oxide nanoparticles (β-Cu 2 O NPs) of cuprite phase with a little tenorite (CuO), 8 especially when they are used in commercial products like inks, lubricants, and coatings 9 as these materials may be cytotoxic 10 as earlier suggested by Han et al 11 Several bactericidal and fungicidal properties of β-Cu 2 O NPs have been found recently. 12 Rakhmetova et al found that β-Cu 2 O NPs can be prepared by a variety of agents.…”

The physicochemical approaches and biological principles in bio-nanotechnology favor specially functionalized nanosized particles. Cuprous oxide nanoparticles (β-Cu2O NPs) of cuprite phase with a little tenorite (CuO) may be very effective in the development of novel therapeutic approaches against several fatalities including A-549 lung carcinoma cell lines. Consequently, the synthesis of β-Cu2O NPs for the improvement in the therapeutic index and drug delivery application is becoming an effective strategy in conventional anticarcinoma treatment. Hence, surface-enhanced nanosized spherical cuprous oxide nanoparticles (β-Cu2O NPs) of cuprite phase were successfully prepared using poly(ethylene glycol) (PEG) as an amphiphilic nonionic surfactant and l-ascorbic acid (K3[Cu(Cl5)]@LAA-PEG) reduced to cuprites β-Cu2O NPs via the sonochemical route. Less improved toxicity and better solubility of β-Cu2O NPs compared with Axitinib were a major reason for producing β-Cu2O NPs from K3[Cu(Cl5)]@LAA-PEG (LAA, l-ascorbic acid, PEG, poly(ethylene glycol) (PEG)). These nanoparticle syntheses have been suggested to influence their cytotoxicity, free-radical scavenging analysis, and reactive oxygen species (ROS) using poly(ethylene glycol) (PEG) and l-ascorbic acid (LAA) as coated and grafted materials due to their dose-dependent nature and IC50 calculations. The surface morphology of the formed β-Cu2O NPs has been examined via UV–vis spectroscopy, Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy with energy diffraction scattering spectroscopy (SEM@EDS), field emission scanning electron microscopy (FESEM), and transmission electron microscopy (TEM) analysis. X-ray diffraction (XRD) and Brunauer–Emmett–Teller (BET) surface analysis results confirm the presence of pure cuprite with a very little amount of tenorite (CuO) phase, Dynamic light scattering (DLS) confirms the negative ζ-value with stable nature. Docking was performed using PDB of lung carcinomas and others, as rigid receptors, whereas the β-Cu2O NP cluster was treated as a flexible ligand.
