“…Hydroquinone was used in commercially accessible cosmetic skin-lightening formulas in European Union nations from the 1950s until 2001 9 . Hydroquinone, on the other hand, may be an element of high molecular aromatic compounds (such as resin), an intermediary, or a byproduct of the decomposition of an aromatic molecule 10 . These chemicals were more hazardous to aquatic: Desmodesmusarmatus, Pimephalespromelas, Daphnia Magna, Aminophenols are frequently employed in industrial chemical syntheses as a dye precursor, coloring hair, fur, and textiles, and as a photographic developer 12 .…”

The resulting antibiotic residue and organic chemicals from the growing global population have a detrimental impact on environmental and human health protection. So, we created a unique B, N-CQDs (Boron, Nitrogen doping carbon quantum dots) based fluorescent nanosensor to investigate novel sensing methodologies for the precise and concentrated identification of antibiotics and phenol derivatives substances to ensure that they are included in the permitted percentages. The as-prepared highly fluorescent B, N -CQDs had a limited range of sizes between 1 and 6 nm and average sizes of 3.33 nm and 2.8 nm in our study. Penicillin and Erythromycin may be detected efficiently using the suggested fluorescence approach, with detection limits of 10 nm and 5 nm, respectively. The novel B, N-CQDs showed high sensitivity and selectivity for phenolic derivatives such as Hydroquinone, Resorcinol, and Para aminophenol, as well as organic solvents such as Hexane, with low detection limits of 0.05µM, 0.024µM, 0.032µM, and 0.013µM in an aqueous medium. The high fluorescence B, N-CQDs probe was examined using transmission electron microscopy (TEM), X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), and UV/VIS spectroscopy. The outcomes were compared to carbon quantum dots (CQDs) that had previously been made from Urea.

“…Since paraffin wax has a similar chemical structure to polyethylene, we decided to use the solubility parameter of polyethylene in calculations (16.7 MPa 0.5 [100]), while the wax's molar volume is equal to 625.56 cm 3 •mol −1 based on its molecular weight and density (approximately 0.9 g/cm 3 ). In turn, the solubility parameter of asphaltenes is about 19.6 MPa 0.5 [92,93], and the molar volume is 704 cm 3 •mol −1 . The above data have allowed for calculating the binodal lines in the first approximation using Equations ( 1)-(3) (marked in Figure 1 with solid black lines).…”

“…Trends in the global economy are such that energy consumption is growing [ 1 , 2 ]. At the same time, reservoirs of fossil fuels are limited, while the demand for petroleum production and consumption is constantly increasing [ 3 ]. Moreover, the increased consumption of fossil fuels is leading to higher concentrations of carbon dioxide, global warming, and a higher carbon footprint.…”

The usual problem of meltable phase-change agents is the instability in their form upon heating, which can be solved by placing them into a continuous polymer matrix. Epoxy resin is a suitable medium for dispersing molten agents, but it is necessary to make the obtained droplets stable during the curing of the formed phase-change material. This work shows that molten paraffin wax forms a Pickering emulsion in an epoxy medium and in the presence of asphaltenes extracted from heavy crude oil. Theoretical calculations revealed the complex equilibrium in the epoxy/wax/asphaltene triple system due to their low mutual solubility. Rheological studies showed the viscoplastic behavior of the obtained dispersions at 25 °C, which disappears upon the heating and melting of the paraffin phase. Wax and asphaltenes increased the viscosity of the epoxy medium during its curing but did not inhibit cross-linking or reduce the glass transition temperature of the cured polymer. As a result of curing, it is possible to obtain phase-change materials containing up to 45% paraffin wax that forms a dispersed phase with a size of 0.2–6.5 μm. The small size of dispersed wax can decrease its degree of crystallinity to 13–29% of its original value, reducing the efficiency of the phase-change material.

“…Bio-oil, the main product from the rapid pyrolysis of biomass, has been successfully used in the preparation of PF in recent years [7][8][9]. Compared with the petroleum-based PF, the biooil phenol-formaldehyde resin (BPF) has similar chemical and physical properties, but a better price competitiveness [10][11][12][13][14][15].…”

“…Compared with the petroleum-based PF, the biooil phenol-formaldehyde resin (BPF) has similar chemical and physical properties, but a better price competitiveness [10][11][12][13][14][15]. However, the components of bio-oil are complex, including hundreds of organic components such as phenols, ketones, aldehydes, acids and sugars [7,[16][17][18]. Some organic components in the bio-oil can directly take part in the resin reaction, resulting in the change of resin structure and properties.…”

In order to clarify the effects of crude bio-oil for phenol-formaldehyde resin, the phenol-formaldehyde resin with bio-oil model compounds (BMPF) were prepared by model compound method. The bonding strength and aging resistance of BMPF were determined, and their microstructure and chemical bonds were also analyzed by scanning electron microscope, Fourier transform infrared spectroscopy, and nuclear magnetic resonance analysis, respectively. The results showed that the components of crude bio-oil had various degrees of effects on the BMPF performance, and the most obvious one is the phenols. The phenols and the ketones of bio-oil had positive effects on the bonding strength. The ketones had the biggest effect on the surface smoothness of BMPF film. But all components of bio-oil could inordinately improve the aging resistance of BMPF. The structural analysis indicated that the effects of bio-oil components on the BMPF performance by changing the resin structure. The CH2 peak in FT-IR and the methylene bridges intensity in NMR of phenol-free BMPF and ketone-free BMPF were smaller, while the results of aldehyde-free BMPF and acid-free BMPF were opposite. And the influence degree of BMPF structure was basically consistent with that of BMPF performance. These results could provide a basis for the modification of phenol-formaldehyde resin by crude bio-oil.
