“…The XRD analysis showed two broad reflections with maximum intensity at 25° and 44° (supplementary material Figure S1). This characteristic indicates that the nano‐carbon black has a low degree of carbon crystallite orientation . Raman spectra has been shown in our previous works to evaluate graphitization levels of material.…”

In this work, a simple and low‐cost method was developed for the simultaneous determination of the antioxidants tert‐butylhydroquinone (TBHQ) and butylated hydroxyanisole (BHA) in the presence of the cationic surfactant CPB by square wave voltammetry (SWV) technique using a carbon black paste electrode (CBPE). The performance of the method was investigated by varying parameters such as pH, electrolyte, and type and concentration of surfactant. Under the optimum conditions of 0.2 mol L−1 phosphate buffer (pH 7.0), 600.0 μmol L−1 of cetylpyridinium bromide surfactant and SWV operating parameters optimized through the Doehlert matrix, the method presented low limits of quantification for TBHQ and BHA (0.23 and 0.26 μmol L−1, respectively) and high precision in successive measurements. The proposed method was applied in mayonnaise, margarine and biodiesel and the accuracy of method was checked by the HPLC technique.

“…High-resolution transmission electron microscopy (HRTEM, JEOL model 2010) was used to investigate the morphologies of the CQDs and Ni-CQDs [35]. Fourier transform infrared spectroscopy (FTIR, Nicolet model 6700) was applied to investigate the chemical compositions and surface functional groups of the two nanomaterials [36]. Friction and wear tests were conducted by using a multifunctional reciprocating tribometer (model CFT-1, Zhongke Kaihua Technology Co., Ltd.) with different loads (8 N, 20 N, and 100 N) and reciprocation speeds (200 rpm, 300 rpm, and 400 rpm, amplitude of 5 mm) for 60 min at room temperature (Approximate 25 °C ).…”

A novel green lubricating oil additive (carbon quantum dot (CQD) particle-doped nickel (Ni-CQD)) was synthesized from citric acid and nickel acetate. The effects of CQD and Ni-CQD nanoparticles on the tribological behaviors of polyethylene glycol (PEG200) were investigated under different loads and reciprocation speeds. The results indicate that CQD and Ni-CQD particles can both enhance the lubrication properties of PEG200. However, the Ni-CQD nanoparticles enhanced the lubrication properties more than the plain CQD particles did. The average friction coefficient and wear rate of PEG200 containing 2 wt% Ni-CQDs were reduced by 35.5% and 36.4%, respectively, compared to PEG200 containing pure CQDs under a load of 8 N and reciprocation speed of 25 mm/s over 60 min. The friction and wear mechanisms are attributed to the fact that friction induces the Ni-CQDs to participate in the formation of a tribofilm, resulting in a low friction coefficient and wear rate.

“…It was found that the soot particles from both fuels were sphere-like in structure and were linked in a chain. The average diameter of the primary soot particles were about 38 nm, measured from the images using the Nano measurer software, which was similar to the results from the TEM images given in [32,33].…”

a b s t r a c tA biomass oil/diesel blend was prepared using an emulsion method and combusted in a diesel engine. An injector was then removed and the morphology, composition, and structure of the carbonaceous deposits on the pintle-type nozzle were characterized using a combination of HRTEM, SEM/EDAX, Raman and XRD. Results showed that the carbon deposition of the emulsified fuel with high crystallinity was greater than that of diesel. The agglomerated particulate diameters of the deposited carbon from diesel and emulsified fuel were approximately 10-30 μm and 50 μm, respectively. The carbon deposition mechanism from the emulsified fuel was attributed to the high oxygen content of the groups leading to increased polymerization and subsequent condensation on the nozzle surfaces that was then carbonised.
