... Additionally, nuclear magnetic resonance (NMR) spectroscopy is valuable for unraveling the molecular dynamics and interaction mechanisms between bio-fillers and bio-plasticizers. Combining these characterization techniques not only facilitates a comprehensive understanding of the bio-composite structure but also aids in tailoring their properties for specific applications, thereby advancing the development of environmental friendly and sustainable materials in the realm of bio-based polymers (Anwaaz & Bharathiraja, 2023;Kavimani et al., 2023;Nagarjun et al., 2023;Saha et al., 2023;Somaiah Chowdary et al., 2023). ...

... This translates into an approximate 102.64% boost in production. In SSSSs, Kumaravel et al. [44] studied the performance of pebble stones and blue metal stones as thermal energy storage materials. For this experimental research, three identical solar stills were fitted with dripping and cooling systems to keep the water level steady. ...

... Mostly neat commercial polymers are used in the industry to get easy-processible production. On the other hand, to obtain enhanced mechanical, thermal, etc., properties fiberreinforced polymer composites are widely used [4,5]. Hot embossing is the process of pressing a molding tool into a semi-finished polymer. ...

... It was observed in the literature that the application of heat treatment on the as-built LPBF sample resulted in a negative impact on its microhardness. Sathies et al. [74] confirm that the sample that has undergone a heat treatment of two hours at 1100 °C and subsequent cooling in a furnace exhibits a microhardness of 175.6 HV, representing a 20% decrease compared to the as-built LPBF sample. Furthermore, microhardness values in samples produced via traditional methods, such as casting, are observed to be lower. ...

... Fig. 1 illustrates the sources of noise inside and outside the vehicle along with their significance [1][2][3][4][5][6] and Fig. 2 illustrates a vehicle's noise source ranking during a pass-by noise test. Since the engine mounting system is the primary connector and offers support between the vehicle's engine and chassis, it has a noticeable impact on the noise an ICE produces [9]. Mounting system noise is presented in Fig. 2 as part of the remaining noise. ...

... Despite the excellent power density, high thermal efficiency, high dependability, durability, low fuel consumption, and specific cost [6], diesel engines generate higher noise levels due to the piston slap [7]. Due to the fixed position of the engine on the vehicle frame and its higher compression ratio-owing to the rougher combustion process and higher structural dynamics of the engine-the vibration of the vehicle body is noted to be greater than with a petrol engine [8]. This has contributed a lot to the noise generation in the engine. ...

... Phenolic resin with a maximum tensile strength and hardness of 4 weight percent carbon nanofiber (CNF) of 43.8 MPa and 37.8 HV, respectively. However, the level of increase gradually declines (Natrayan et al., 2021). The innovative component (polypropylene reinforced with biocarbon and Miscanthus fiber, instead of traditional materials like talc and colorant used in conventional components) has emerged to be environmentally favorable and can help meet the fuel economy emission regulations over the conventional component. ...

... Additionally, wear-resistant coatings are frequently utilised in internal combustion engines in addition to gas turbines. In addition, thermal barrier coatings, more commonly referred to as TBC, are routinely utilised in these machines [48][49][50]. As a result of the high temperatures at which these parts and components operate, TBCs are utilised in order to extend the amount of time during which they can be utilised. ...
