“…41 The absorption peak at 1067 cm −1 is the stretching vibration of C−O in the alcoholic hydroxyl group. 42 Compared with CCNM, absorption peaks on SDBS-CCNMs at 1160, 613, and 484 cm −1 are increased by SDBS-modified carbon nanomaterial. At 1160 cm −1 , there is an overlap of the sulfonic acid group S�O stretching vibration absorption peak 43 and the C−O stretching vibration absorption peak.…”

In order to make porous carbon nanomaterial more suitable for the adsorption thermal energy storage field, it is necessary to modify the carbon nanomaterial to enhance water vapor adsorption capacity. This work investigated the influence of anionic surfactant sodium dodecylbenzenesulfonate (SDBS) modification on the physicochemical properties of coffee-shell carbon nanomaterials (CCNMs). The physicochemical properties of carbon nanomaterials were characterized. Water vapor adsorption isotherm, thermodynamics, and kinetics were analyzed to investigate further adsorption behavior over the CCNMs. The results suggest that the highest adsorption capacity of water vapor for modified CCNM (SDBS-CCNM) is up to 833.2 mg/g, with 2% SDBS mass fraction, 500 °C calcination temperature, and 30 min calcination time. However, its BET specific surface area and average pore size are only 2018 m 2 /g and 1.915 nm, respectively. On the other hand, the modification improved the amount of total surface oxygen-containing functional groups (SOFGs), mainly phenolic hydroxyl of SDBS-CCNM, compared with unmodified CCNM, which is conducive to water vapor adsorption on SDBS-CCNM under lower relative pressure. And water contact angles are less than 34°. Furthermore, the dynamic adsorption process of water vapor on CCNMs was described by the Bangham model, which suggests that surface adsorption center sites of SDBS-CCNMs play a significant role in the water vapor adsorption process under lower relative pressure. As relative pressure increases, water molecules form clusters around the water molecules previously adsorbed at the active site through hydrogen-bonding interaction. When the clusters are large enough, water molecules begin to fill the pores of the CCNMs until the adsorption process becomes saturated. All the above results indicate that carbon nanomaterials are hydrophilic. Thus, the modified CCNM obtained in the present work can be a potential carbon nanomaterial with an excellent adsorption capacity for adsorption thermal energy storage.

The coating of Fe 3 O 4 -NPs with SM and HS is a new strategy to increase the efficiency of nanofertilizers and improve the quality and resistance of plants against environmental stresses. In this study, aqueous extracts of spinach and guar were used for the green synthesis of Fe 3 O 4 -NPs and CuO-NPs, respectively. The surface of the Fe 3 O 4 -NPs was then coated with SM and HS. UV− vis, thermogravimetric analysis, Fourier transform infrared spectroscopy, X-ray diffraction, scanning electron microscopy, transmission electron microscopy, and dynamic light scattering analyses all confirmed the formation of nanoparticles. The first experiment was carried out as a factorial in a completely randomized design. The effect of nanoparticles and determination of the optimal concentration of Fe 3 O 4 -NPs, SM, HS, Fe 3 O 4 -SM, and Fe 3 O 4 -HS with concentrations (control, 25, 50, 75, and 100 mg/L) and two methods of application (seed priming and addition to planting medium) were determined. The results showed that seed priming with 75 mg/L Fe 3 O 4 -NPs and single-stranded and multibranched polyamines improves germination and increases the dry matter content and seedling length. Then, a pot test was performed for the effects of Fe 3 O 4 -NPs and single-branched and poly branched polyamines under CuO stress conditions. The factors were six polymers (control, Fe 3 O 4 , SM, Fe 3 O 4 -SM, HS, and Fe 3 O 4 -HS) and 60, and 120 μL). Under stress conditions, the application of Fe 3 O 4 -HS caused an increase of 34.11, 41, 39.37, and 68.25% in the activity of CAT, POX, PPO, and proline, respectively, and a decrease of 46 and 33.33% in MDA and hydrogen H 2 O 2 compared to the control treatment. Also, the use of NPs under stress conditions caused more absorption of N and Fe by the plant. Consequently, the plant's resistance to CuO stress conditions increased.

“…35,36 Some nanoparticles have also been reported to be effective in the degradation of MTZ. Metal oxide NPs such as titanium dioxide (TiO 2 ), 37 zinc oxide (ZnO), 38 and iron oxide (Fe 3 O 4 ), 39 have been extensively studied for their ability to adsorb and degrade various pollutants including metronidazole. Zerovalent metal NPs such as iron NPs, 40 copper NPs, 41 palladium NPs 42 have also been shown to be effective in removing metronidazole.…”
