“…Biomaterials and their derivate could provide unique structures that are not obtainable using conventional ceramic processing methods ( Bahrami et al., 2016 ). Of all the ceramics derivatives obtainable from biomaterials, the most investigated of them all is silicon carbide synthesized from various plants ( Bahrami et al., 2016 ; Aigbodion and Ezema, 2019 ). Most of the oxides present in the derivatives of biomaterials are strengtheners in MMCs ( Ikubanni et al., 2020b ).…”

“…When PKS are used for energy and fuel production, the residue obtained is known as palm kernel shell ash (PKSA). They can be scientifically generated through carbonization in an electric furnace at 900 °C for about 4–5 h ( Aigbodion and Ezema, 2019 ). The PKSA has been found to be useful in the development of MMCs as partial reinforcement with synthetic ceramic materials such as SiO 2 , Al 2 O 3 , and so on.…”

“…The PKSA has been found to be useful in the development of MMCs as partial reinforcement with synthetic ceramic materials such as SiO 2 , Al 2 O 3 , and so on. Sol gel method has also been used in obtaining PKSA in nanoparticle forms ( Aigbodion and Ezema, 2019 ).

The paper focuses on collection of information on recent multifaceted usage of biomass materials with critical examination on its sustainability. The use of biomass is becoming popular, with wide global acceptance as it is considered as green technology. The use of biomass products across industrial parallels, the material combination and production processes were elucidated in this paper. Biomass materials are seen as affordable alternative to conventional materials for domestic and industrial applications. The multifaceted use of biomass, which includes, energy generation, metallurgical applications, construction purposes, reinforcement in metal matrix composite, microelectromechanical system, biochemical and traditional medicine were discussed. This underscores the need to develop a sustainable plan to meet with its diverse usage to be beyond laboratory efforts. This paper examined whether the availability of biomass can sustain its multifaceted usage or not. It also examined the modalities to ensure sustainable use of biomass. Different policies were highlighted and discussed in line with continuous multifaceted use of biomass.

“…A number of current research papers discuss the probable advantages of e-ISSN: 2289-7771 387 reinforcing A356 with organic materials (e.g. [10][11][12][13]), whereas other investigators have exhibited crucial concern about specific property enhancement for the A356 reinforced composites, including corrosion resistance [14], surface enhancement [15], microstructural and associated property enhancement through heat treatment [16][17][18][19][20][21]. The reported studies are nonetheless principal papers regarding metallic reinforced A356 alloy while very scanty papers were noted for organic reinforced A356 alloy, indicating a very restricted number of experimental research available in the literature on A356 alloy organic reinforced composites.…”

The A356 alloy is widely known to exhibit an extremely superior casting, machining, mechanical, and corrosion resistance properties. Despite these, it constitutes an environmental nuisance at its improper disposal for worn-out engine blocks. Also, organic reinforcements have the potentials to reduce the environmental impacts of composites. Consequently, there exits significant research potential to fuse A356 alloy with organic materials to obtain enhanced composite properties. In the area of aluminium matrix, as melting and solidifications of materials are done the accuracy of measurements is driven by the huge array of process parameters and the geometrical aspect of cast components is important. For these reasons, we attempt to solve the problem of optimising the geometry of casts in a complicated scenario with the use of the robust Taguchi's methods. To optimise the framework, the significant process parameters are identified and their effects studied in a route using Taguchi, Taguchi-Pareto and Taguchi–ABC methods. Parameters such as the volume of the cast, length, weight, density, height, width, breadth, weight loss and the total weight of organic materials infused into the melting process were studied for parametric changes, interactions and optimisation with L27 orthogonal array. The analysis of variance for the A356 alloy cast revealed that the density parameter of cast 1 had the highest and major significant effect on the casting process with a variance of 333573, followed by weight parameter of casts 1 and 2, total weight of organic material parameters and weight loss with the variance values of 0.007, 0.005, 0.001 and 0.004, respectively. The variance of other parameters was insignificant to the A356 alloy cast.

The recycling of agro‐waste as complementary reinforcements has received significant recognition in the development of aluminium matrix composites. Hence, this study examines the corrosion behavior of Al6063 reinforced with hybrid SiC/PKSA (palm kernel shell ash) particles. Through various ratios of SiC and PKSA particles in Al6063 alloy, composites were fabricated by double stir casting. Samples were cut and metallographically prepared for 1 M H2SO4 solution corrosion experiments. Gravimetric, potentiodynamic polarization and electrochemical impedance spectroscopic analyses were employed. The composites corroded initially at relatively high rates, gradually declining during long immersion times in the acidic solution. The intersection of reinforcements at the general surfaces of the composites where flawed oxide skins predominate acted as active sites for corrosion initiation. From potentiodynamic polarization studies, the corrosion currents increased with time for all specimens, with A9 being 1075.65 μA/cm2 at 72 h as against 857.99 μA/cm2 at 24 h of measurement. The corrosion potentials for all the specimens hovered around −654.00 to −647.22 mV. Bode plots revealed similar electrochemical reactions over all the substrates' surfaces. The relative corrosion resistance by the specimen depends on the oxide films' nature as the cathodic interfacial reinforcements dropped off into the acidic environment.
