“…For the analysis of various chemical elements in the oil, GC-MS is an important and quick technique. During pyrolysis, the three primary components of biomass, such as cellulose, hemicellulose, and lignin, were decomposed into various chemical elements such as alcohol, alkanes, alkenes, and phenolic components [54,55]. Table 3 represents a list of chemical components determined by GC-MS. As illustrated in the table, the biomass is typically broken down into phenolic compounds.…”

In this study, the impacts of co-pyrolyzing wood-based biomass from Ficus benghalensis with PET on liquid oil output, reactivity, and heating values were investigated. The effects of temperature on the product distribution of individual pyrolysis and the biomass-plastic ratio on co-pyrolysis were investigated. For individual pyrolysis, a maximum amount of 40.8 wt (%) liquid oil was obtained from biomass at 450°C. On the other hand, a maximum of 59.5 wt (%) liquid oil was obtained from PET at 500°C. The co-pyrolysis experiments were conducted by blending PET with biomass at different percentages, such as 20%, 40%, 60%, and 80%. At 60% addition of PET, a more positive synergistic effect was identified due to radical secondary reactions. In addition, the physical and chemical characterization studies conducted on pyrolysis oil showed that biomass and plastic materials could be used to make valuable chemicals.

“…SiCp/Al composites made by mechanical stirring and other methods can have the characteristics of high plasticity for metals and high brittleness for ceramics. SiCp/Al composite is widely used in aerospace, electronic packaging, high-speed rail, microwaves and other fields because of its low density, light weight, high specific strength, small thermal expansion coefficient, and other excellent characteristics [ 1 , 2 , 3 ]. However, SiC particles with high hardness and wear resistance are mixed in SiCp/Al composites, which seriously affects the service life of traditional machining tools and the surface quality of the workpiece.…”

SiCp/Al composites have excellent physical properties and are widely used in aerospace and other fields. Because of their poor machinability, they are often machined by non-traditional machining methods such as electrical discharge machining (EDM). In the process of EDM, due to the “shielding” effect of the reinforced particles of SiC, the local ejection force is low during the processing process, and it is difficult to throw the reinforced particles smoothly, which ultimately leads to a low material removal rate and poor surface quality. In this paper, a high–low-voltage composite ejecting-explosion EDM power supply is developed to explore the explosive effect of reinforced particles in the ejecting-explosion EDM process and the unique process law of the explosion process. The experiment platform uses self-developed CNC machining machine tools based on an ejecting-explosive EDM power supply, and the influence of a detonation-increasing wave on the processing of SiCp/Al composites with different volume fractions was studied by changing four factors: the open-circuit voltage difference, pulse current difference, pulse phase difference, and pulse width difference of the back wave behind the step front. The material removal rate and surface roughness were measured. The research results showed that the material removal rate could be increased to 164.63%, and the material surface roughness could be increased to 30.03% by adjusting the high and low pulse current difference from 1 A to 8 A. When the voltage difference between high and low wave (HLW) pulses increases from 40 V to 120 V, the material removal rate can be increased to 150.39%, and the material surface roughness can be increased to 20.49%. The material removal rate increases with the increase in pulse phase difference and open-circuit voltage difference. With the increase in peak current difference and pulse width difference, the material removal rate becomes faster at first and then slower. The surface roughness of materials increases with the growth of open-circuit voltage difference, peak current difference, pulse width difference, and pulse phase difference.

“…The sand casting comes from significant constraints on geometrical and higher timeframes attributable to the participation of pattern formation. The increasing sophistication of the design of numerous structural applications necessitates the use of advanced pattern creation, thus restricting the use of sand-casting techniques [17]. In an industrial plant contained within a single room, sand moulds might be utilized to construct a colossal casting [18].…”

3D printing has been recognized to be such a game-changer in manufacturing that it has now permeated virtually every aspect of the industry, including mould and die casting. A thorough examination of 3D printing's past, present and future in the business is provided here. Casting procedures may be enhanced or drastically altered by 3D printing. The design of goods, assemblies, and parts will be transformed by 3D printing, which is more than just a manufacturing technology. With the aid of 3D printing, sand casting is a technique that can make complex components out of almost any metal alloy at a reasonable cost. Using this integration, producers may build massive components in the least amount of time. It has also established a distinctive place in other casting elements; Examples include the ceramic shell, sand mould sand core, and wax pattern, we'll learn more about sand casting and 3D printing this week.
