Abstract In this paper, we introduced, discussed, and investigated analytical-approximate solutions for nonlinear time fractional gas dynamics equations in terms of conformable differential operator. The proposed algorithm relies upon the conformable power series method and residual error of the generalized Taylor series in terms of the conformable sense. This technique provides analytical solutions in the form of rapid and accurate convergent series in terms of the multiple fractional power series with easily computable components. In this direction, error estimation and convergence analysis for solutions of fractional gas dynamics equations are provided as well. Eventually, several physical examples are tested to justify the theoretical portion and give a clear explanation of dynamic systems for the proposed model for different orders of fractional case The obtained numeric-analytic results indicate that the current algorithm is simple, effective, and profitably dealing with the complexity of many nonlinear fractional dispersion problems.

Abstract An analytical solution for stresses in a plastically deformed cylinder made of a functionally graded material (FGM) under internal pressure is provided. The cylindrical material is composed of two metal powder particles manufactured using centrifugal casting. While Poisson’s ratio is assumed constant, Young’s modulus is a power function of the radius. The von Mises yield criterion is used under the plane-strain condition. The constitutive material model obeys the Ludwik power law, with the yield strength and work-hardening coefficient as functions of the radius. The stress distributions along the radial direction for the elastic, elasto–plastic field and beyond plastic collapse cases were analyzed. To study the effect on the plastic zone in FGM, in addition to pressure, the gradient index was made to vary from −2 to 2 and different cylinder aspect ratios ranging from 1 up to 3 are considered. A finite-element simulation was run for comparison and validation of the analytical solution. The results showed a good agreement between the two methods.

Abstract Pyrolysis is becoming increasingly popular as a method of producing liquid yield from biomass. It has the potential to help build a sustainable renewable fuel market while simultaneously maintaining environmental sustainability. In the present study, cow hooves are pyrolyzed in a fixed-bed batch reactor to investigate product dispersion and determine optimal temperature parameters for optimizing pyrolysis oil yield. Temperature effects on the distribution, elemental content, and physical qualities of major pyrolysis products, such as pyrolysis oil and bio-char, are investigated. At a pyrolysis temperature of 500 °C, the maximum pyrolysis oil production was found to be 50.50 wt%, with the amount of bio-char excluding the gas being 27.20 wt%. A CHNS analyzer, Gas chromatography-mass spectrometry (GC-MS), and Fourier-transform infrared (FTIR) spectroscopy are used to investigate the chemical composition of pyrolysis oil generated under optimal conditions. The fuel properties of the pyrolysis oil are also determined, and it was discovered that it has a favourable fire point, flash point, and pour point. The density of the pyrolysis oil was 1.03 kg/L, the viscosity was 10.2 cSt, and the heating value was 22.7 MJ/kg. The FTIR analysis of the pyrolysis oil reveals that it contains functional groups, such as alkene, carboxylic acid, alcohol, ether, and ketone. According to the GC-MS analysis, the principal components are ester (40%), fatty acids (31%), phenol (3.8%) and p-Cresol (2.9%). Unsaturated fatty acids are abundant in the pyrolysis oil from cow hooves, while saturated fatty acids are in short supply. According to the findings of this study, cow hoof pyrolysis oil has the potential to be used as a source of biodiesel.

Abstract The present study reports the synthesis of gold nanoparticles (AuNPs) using ‘sea grapes’ (Macroalgae) of Caulerpa racemosa extract in a simple, fast and environmentally friendly biogenic method. The formation of spherical, stable, polycrystalline nanoparticles with an average size of 18–45 nm was demonstrated by UV–vis spectroscopy, SEM, high-resolution transmission electron microscopy and X-ray diffraction measurements. Furthermore, FTIR analysis confirmed the presence of phytochemical constituents in the form of functional groups involved in AuNPs synthesis. Antimicrobial activities confirmed that Gram-negative bacteria, here represented by Escherichia coli, were found to be more sensitive to synthesized AuNPs than Gram-positive bacteria, represented by Staphylococcus aureus. The synthesized nanoparticles also showed cytotoxicity against human lung cancer cells (H460) with an IC50 value of 25 µg/mL. Furthermore, our findings show that AuNPs derived from C. racemosa extract are able to induce apoptosis activation via extrinsic and intrinsic pathways and mitochondrial pathways. These findings lay the groundwork for future research against emerging multi-drug resistant bacterial pathogens, as well as lung cancer treatment.
