“…Figure S1 presents representative ATR-FTIR spectra of layers #1, #2, #4, and #5 and two library spectra with the best match, clearly showing the presence of alkyd-based enamel resins [33,34,35] as the major organic species in these layers. The Raman spectral data also support the presence of alkyd resins in these four layers [36].…”

“…On the other hand, the laser beam employed in RMS can induce damage to the samples and the interference by the fluorescence often encountered in RMS needs to be minimized, which are not problems in ATR-FTIR measurements. ATR-FTIR imaging provides the ATR-FTIR spectrum at each pixel in the image field for the samples, whereas RMS mapping to obtain the spatial, chemical heterogeneity for the samples takes a much longer time as RMS images are acquired by the point-by-point scanning mode [26,27,28,29,30,31,32,33].…”

For the forensic analysis of multi-layered paint chips of hit-and-run cars, detailed compositional analysis, including minor/trace chemical components in the multi-layered paint chips, is crucial for the potential credentials of the run-away car as the number of layers, painting process, and used paints are quite specific to the types of cars, color of cars, and their surface protection depending on the car manufacturer and the year of manufacture, and yet overall characteristics of some paints used by car manufacturers might be quite similar. In the present study, attenuated total reflectance-Fourier transform infrared (ATR-FTIR) imaging, Raman microspectrometry (RMS), and scanning electron microscopy/energy-dispersive X-ray spectrometric (SEM/EDX) techniques were performed in combination for the detailed characterization of three car paint chip samples, which provided complementary and comprehensive information on the multi-layered paint chips. That is, optical microscopy, SEM, and ATR-FTIR imaging techniques provided information on the number of layers, physical heterogeneity of the layers, and layer thicknesses; EDX on the elemental chemical profiles and compositions; ATR-FTIR imaging on the molecular species of polymer resins, such as alkyd, alkyd-melamine, acrylic, epoxy, and butadiene resins, and some inorganics; and RMS on the molecular species of inorganic pigments (TiO2, ZnO, Fe3O4), mineral fillers (kaolinite, talc, pyrophyllite), and inorganic fillers (BaSO4, Al2(SO4)3, Zn3(PO4)2, CaCO3). This study demonstrates that the new multi-modal approach has powerful potential to elucidate chemical and physical characteristics of multi-layered car paint chips, which could be useful for determining the potential credentials of run-away cars.

“…The alkyd resins contain reactive sites such as carboncarbon double bond, polar ester group, methylene group attached to carbonyl site and allylic methylene group. [41] Also, the dye can be easily stick to the alkyd resin due to its adhesive property. Hence the alkyd resins are effectively adsorbing various pollutants and dyes from wastewater.…”

“…In recent years, the researchers have attracted silica nanoparticles because of their regular structural characteristics, larger surface area, appropriate pore diameter, good thermal and chemical stabilities, ease of surface modification, the selectivity of organic pollutants, economical regeneration and reusability. [41][42][43] Besides their advantages, alkyd resin containing adsorbents exhibits some limitations such as low adsorption capacity and requires long adsorption time, both are the important parameters for being a compatible adsorbent. Hence in this paper, we reported for the first time a newer approach towards the dye adsorbent by using GO, alkyd resin and silica nanoparticles.…”

In this article, we report a facile strategy for the synthesis of G@SiO2‐AR by using silica nanoparticles, which are coated with graphene and alkyd resin. During the synthesis of G@SiO2‐AR, the silica particles have been prepared in situ by hydrolysis of tetraethyl ortho silicate (TEOS). The G@SiO2‐AR has been employed to remove the methylene blue (MB) from aqueous solution. G@SiO2‐AR has a strong affinity to adsorb MB as MB is a cationic dye and it is strongly attracted by anions induced by deprotonation of acid functionality on GO. The detailed adsorption characteristics of G@SiO2‐AR, such as adsorption kinetic and adsorption isotherm has been investigated. The efficiency of dye adsorption on a G@SiO2‐AR has been investigated under various parameters such as contact time, temperature, and pH. The adsorption experiment has been carried out by keeping the constant adsorbent dose in 50 mL of 50 ppm dye solution with varying time intervals such as 5, 10, 15, 20 and 25 min at room temperature. We got better results at 20 min and the dye removal efficiency of G@SiO2‐AR and SiO2@AR is 95.08 % and 87.32 % respectively at room temperature. Also, we carried out the same experiment at different temperatures ranging from 298, 308 and 318 K, out of which the highest adsorption efficiency of above‐mentioned adsorbents has been observed at 318 K up to 99.72 % and 93.16 % respectively. Kinetic data has been shown that the adsorption phenomenon follows the pseudo‐second order kinetic model, while adsorption isotherm follows the Langmuir adsorption isotherm.

“…Alkyd resins are unsaturated oil-modified polyesters synthesized from polycondensation reactions between polycarboxylic acids and polyalcohol in the presence of various traditional vegetable oils such as soybean oil [4][5][6][7], castor oil [8,9], linseed oil [10], sunflower oil [1,7,11,12], and coconut oil [13]. Since alkyd resins were first introduced many decades ago they have enjoyed consistent annual growth and received great importance because of low processing cost, availability of raw materials, and ease of applications [1,14]. These resins are widely used in various coating industries as binders, paints, inks, and varnish [15].…”

Alkyd-based printing ink vehicles were successfully prepared from waste frying oil. Three alkyd resins were synthesized using different ratios of phthalic anhydride. Properties of the 3 prepared resins were measured and compared with virgin oil alkyd resin and commercial alkyd resin. Viscosities of the obtained ink vehicles ranged from 8.6 to 34.9 poises. The vehicles were also completely compatible with carbon black for formulating black printing inks. Preliminary properties of the 3 formulated inks were evaluated and compared with black printing ink prepared from virgin oil alkyd and commercial alkyd. The formulated inks had satisfactory viscosity and tackiness as properties suitable for a variety of printing applications. The 3 synthesized inks had rub resistance values ranging from 4.61 to 5.75 %, slightly higher than the rub resistance of virgin oil alkyd ink and commercial alkyd ink. Particle fineness and water tolerance properties of the 3 formulated inks were comparable with virgin oil alkyd ink and commercial alkyd ink. Results suggested that waste frying oil has potential application as a raw material in the printing ink industry.
