This growth intensified the importance of innovative thermal management strategies to ensure safe and efficient vehicle operation. This paper aims to comprehensively review and discuss recent research investigating nanofluid battery thermal management systems (BTMS). Nanofluids are proposed as promising coolants as they possess enhanced thermal performance owing to their higher thermal conductivity compared to conventional fluids. Studies investigating nanofluid BTMSs can be divided into experimental and numerical studies investigating the effects of varying base fluid, nanoparticle type and concentration on thermal performance and pumping power. The overall trend of the reviewed studies displays an improvement in thermal performance with the increase of nanoparticles concentration, coupled with higher pumping power due to the higher viscosity values resulting in higher friction, with reviewed studies demonstrating nanofluids BTMS thermal improvements in the range of 2.9 – 30.5 % with pressure drop increase in the range of 14 – 70 % compared to the base fluid. The most commonly investigated types of nanoparticles are aluminium oxide (Al₂O₃), copper oxide (CuO), and silver oxide (AgO), with concentrations in the range of 0.1 – 5 %.

Thermoelectric generators (TEGs), which work basically on the Seebeck effect can successfully transform input heat from numerous applications into valuable electrical energy, as well as power electronic devices and sensors on their own. However, obstacles include increasing the temperature difference and creating novel materials to improve electrical output and efficiency. Accordingly, this paper discusses these problems by providing a thorough examination of available strategies to enhance the thermoelectric performance. In this study, a variety of materials is presented, starting by the standard used conventional organic and inorganic thermoelectric (TE) materials. Organic materials, such as polyaniline and poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT) composites, acquired ZT values ranging from 0.5 to 1.0, demonstrating their promise for versatile and low-cost applications. At extreme temperatures (∼500 K), inorganic materials such as bismuth telluride (Bi₂Te₃) and lead telluride (PbTe) achieved ZT values around 2.0, indicating great efficiency in power production. Bi₂Te₃/PEDOT, a hybrid material with organic and inorganic components, demonstrated improved performance with ZT values of 1.5–2.0 due to the synergistic effects of its constituents. Novel composite materials, such as Bi₂Te₃-carbon nanotube (CNT) composites and using graphene, developed to optimize thermal and electrical characteristics, enhanced device performance by up to 25% over standard materials, with ZT values ranging from 1.8 to 2.2. In addition, in the present study the new recent materials after applying enhancement methods will be presented. These new materials are developed by different methods and synthesis such as doping, superlattice and heterostructure materials and other methods will be discussed. The main findings indicate that the strategic use of these advanced materials may significantly increase the efficiency and output power of TEG devices, making them more practical for a wide variety of applications.

This work conducts a review study on the coupling of this technology with the various types of solar stills. The performance of each type of solar still in conjunction with a solar heater is examined throughout the study, along with the viability of doing so economically. Furthermore, various environmental studies are offered on this kind of assembly to examine how it affects reducing carbon emissions.

Traditionally, this type of cutting tools were manufactured by powder metallurgy and machining processes, but in this instance Additive Manufacturing processes allowed the customisation of the geometries and eliminated the need of dies to manufacture these tools, leading to economic savings. The study analysed, from different perspectives, the viability of these interchangeable inserts as cutting tools. These approaches included qualitative studies of chip formation and cutting-edge wear as well as thermal and roughness analysis of specimens tested under different conditions. The behaviour of H13 Tool Steel cutting inserts on cylindrical specimens of EN AW-2030 aluminium alloy was compared with commercial carbide inserts, being observed that the chip types produced were extremely similar between those obtained by commercial and those from Additive Manufacturing, particularly in dry conditions. The qualitative study of insert wear showed that AM inserts presented overall larger contribution of built-up edge (BUE) and plastic deformation of the tip, with greater incidence at cutting speeds of Vc = 60 m/min and feed rate of fz = 0.1 mm/r. Regarding thermal analysis, the AM inserts revealed a slightly more abrasive behaviour, resulting in a temperature increase throughout the machining process of approximately 70 °C, with no significant influence from the increase in cutting speed. The study of the surface finish offered average roughness results (Ra) of 0.58 µm for commercial inserts, 1.78 µm in AM inserts with dry tests and 2.06 µm in this same type of insert but tested with lubrication.
