“…The strong band at 1164 cm −1 is due to the C–O bond. 43 The spectra of O 2 plasma/biopolymer-treated polypropylene sample, a significant increase in the band intensity between 3600–3200 cm −1 as a result of increasing the content of hydrogen-bonded –OH group. Moreover, the typical bands of amide I, II, and III of proteins can be distinguished easily.…”

Polypropylene (PP) has unique competitiveness with other synthetic fibers due to its suitable spinnability, availability of raw materials, and low processing cost. PP fabric exhibits excellent chemical, physical, and mechanical properties, such as a light texture, adequate tensile strength, and resistance to most chemicals. However, the absence of reactive functional groups in PP fiber, besides its high crystallinity, results in hydrophobic surface, low affinity to dyestuffs, and poor antistatic properties, which restrict its use in the clothing field. Herein, a water- and energy-saving, eco-friendly finish is proposed to render PP desired properties suitable for textile applications. The surface of PP fabric was activated using oxygen and nitrogen plasma radiations. The plasma-irradiated PP fabric was post-treated with two renewable eco-friendly proteinic biopolymers, namely gelatin and sericin, in the presence and absence of a crosslinking agent. The effects of different process conditions on the properties of the modified PP, including the duration of plasma exposure, the concentration of biopolymer, and treatment temperature were monitored. The affinity of the treated PP fabric towards anionic and cationic dyes was evaluated. The findings of this study demonstrated that the comfort attributes of the plasma/biopolymer-finished fabrics, such as the induced antistatic properties, wettability, and ultraviolet protection, were remarkably improved. The plasma-mediated biopolymer-finished PP fabrics were found dyeable with cationic and anionic dyes. The change in the chemical and morphological structures of PP fabrics was monitored using Fourier transform infrared spectroscopy, scanning electron microscopy, and energy dispersive X-ray spectroscopy.

“…The spectra of B100 displayed the peak at 1.2 ppm as well as at 1.59, and this 1.59 ppm is that of methylene of carbon-chain, and beta-carbonyl methylene. The signal of -OC=O-CH 2 is reported in all biodiesel blends at around 2.28 ppm [18,40,41].…”

“…Monitoring the band in the range between 3500-3400 cm −1 is useful to assess the stability of biodiesel due to the additional carbonyl groups that are formed during oxidation [17]. Chatterjee et al (2022) analyzed oxidation products of biodiesels by 1 H nuclear magnetic resonance (NMR) and studied various fatty acids on glycerol by 13 C NMR [18]. Alexandri et al (2017) reviewed the method of high-resolution NMR spectroscopy in determining the structure and fatty acid composition of the unsaturated lipids in the solution.…”

The demand for sustainable alternative-fuels in the transportation and agriculture domains is essential due to the quick depletion of petroleum supplies and the growing environmental challenges. The ternary-blends (diesel, biodiesel, and Methyl oleate) have the ability to report the existing challenges in this area because they offer significant promise for reducing exhaust emissions and improving engine performance. In the current work, soy methyl ester is blended with methyl oleate and diesel. The emissions and performance of blended biodiesel was conducted in common rail direct injection engine (CRDI). The characterization and physical properties were also evaluated by utilizing various methods like Fourier-Transform Infrared Spectroscopy (FTIR), UV-vis Spectroscopy (UV-vis), and Nuclear Magnetic Resonance. FTIR spectra showed the existence of the strong C=O, indicating the presence of FAME at 1745 cm−1. Again, UV-vis has reported the appearance of conjugated dienes in the oxidized biodiesel. The results indicated all blended samples retained the properties of diesel. The addition of methyl oleate improved brake specific fuel consumption of blended biodiesel almost near to diesel. D50::S80:M20 produced a mean reduction in hydrocarbon 42.64% compared to diesel. The average carbon monoxide emission reduction for D50::S80:M20 was 49.36% as against diesel.
