“…In a study by Gubicza et al [31], using a mixture of large grain (1-10 µ m) and ultra-fine grain (100 nm) Al, they obtained UTS about two times higher, as compared to the present study, with better ductility. Shi et al [1] extruded ultra-fine air atomized Al-4Y-4Ni and Al-4Y-4Ni-0.9Fe (in at.%), with UTS as 422 and 478 MPa measured at room temperature, YTS measured as 394 and 470 MPa, while strain at failure was determined as 16.3 and 7.2%, respectively. It should be noted that they used specimens with a very small gauge length (only 1.3 mm), which resulted in higher reported values.…”

“…Due to their low density, aluminum alloys reinforced with various particles have been developed for weight-critical applications, which have a better specific strength compared to the basic matrix material. However, when reinforcing particles are added to the base metal, the ductility of the composite material is significantly worse, although there are beneficial effects on specific strength and wear resistance [1][2][3][4][5]. The low ductility and manufacturing problems prevent a wider application of aluminum matrix composites (AMC) [6].…”

An industrial press was used to consolidate compacted aluminum powder with a nominal diameter in the range of 1 µm. Direct and indirect hot-extrusion processes were used, and suitable process parameters were determined from heating conditions, ram speeds and billet temperatures. For comparison, a direct-extrusion press for hot extrusion of a conventional aluminum alloy AA 1050 was used. The extruded Al powder showed better mechanical properties and showed a thermal stability of the mechanical properties after annealing treatments. To increase the theoretical density of the directly extruded Al powder, single-hit hot-compression tests were carried out. Activation energies for hot forming were calculated from hot-compression tests carried out in the temperature range 300–580 °C, at different strain rates. Processing maps were used to demonstrate safe hot-working conditions, to obtain an optimal microstructure after hot forming of extruded Al powder.

“…Water pollution is exceedingly difficult to reverse. Natural water filtration procedures can take years, decades, or even centuries to eliminate all hazardous substances from the water, and even the most costly contemporary treatments can take years [7,8]. There are two kinds of pollutants to be handled.…”

Innovative technologies enable businesses to stay competitive in marketplace while also increasing profits in manufacturing of nanocomposites for water treatment. Aforementioned driving factors resulted in adoption of a number of innovative technologies, and no other trend has had a greater impact in recent years than Industry 4.0. Industry 4.0 is a comprehensive term that encompasses data management, manufacturing competitiveness, manufacturing processes, and efficiency. The term “Industry 4.0” refers to a group of key enabler technologies, such as cyber physical models, Internet of Things (IoT), artificial intelligence (AI), and big data analytics, including embedded devices which are all significant components to the mechanized and digitized industrial environments. AI approaches have been used for water treatment processes as well as desalination in recent years for optimizing the process along with providing realistic answers to water scarcity and water pollution-related issues. AI applications have been used to predict and minimize water treatment process operational costs by lowering costs and optimizing chemical utilization. Several AI models are successful and accurate in predicting effectiveness of various adsorbents used in the removal process of a variety of contaminants from water. To identify the current level of research and future development prospects of smart manufacturing, this study uses a comprehensive literature review technique for manufacturing sustainability of nanocomposite fabrication for water treatment applications. The model provided will help to create a baseline for AI and hybrid models in the water treatment and wastewater management sectors, allowing for the increased performance and innovative growth. It will serve to provide the framework and give guidance for researchers interested in creating superior nanocomposites for waste and fresh water treatment and management using Industry 4.0. This study looks at a variety of AI approaches as well as how they may be used in water treatment, with an emphasis on pollutant adsorption. This assessment also identified certain obstacles and research gaps in the field of AI applications in water treatment processes.

“…Ever more demanding applications are pushing the limits of MCU designs due to their requirement for more processing power, lower power consumption, and larger memory capacity. One of the most onerous requests is for greater embedded memory, which can hold larger and more intricate firmware [9,10]. ePCM addresses these chip-and system-level challenges while meeting AEC-Q100 Grade 0 vehicle norms and operating at temperatures up to +165 °C.…”

PCM (phase-change memory) is a memory innovation that has gained prominence as a capacity-class memory for computer systems. It is made up of a tiny functional amount of phase-change material that is located in the middle of two electrodes. In PCM, data is kept by utilizing the difference in electrical resistance between a crystalline phase, which has a high resistance, and its amorphous phase, which has a low resistance. Using electrical pulses, the phase-change material would be shifted from a high to the low conductive region and conversely. However, the device’s material science concerned with PCM has been generally studied, and questions remain regarding their electrical, warm, and fundamental aspects since its publication in the 1960s. One major downside of PCM is its low heat conductivity, which causes delays in the energy charging/discharging procedure and hardware efficiency. As a result of this, one of the primary focuses of PCM studies has been the improvement of PCM’s heat conductivity through the utilization of nanotechnology and nanomaterials. Nanotechnology has been developing ultrasmall nanoparticles to improve traditional PCMs’ thermophysical characteristics. These nanomaterials, such as metal, metal oxide, and carbon, will significantly boost PCM’s thermal properties, including supercooling, viscosity, and heat capacity. An overview of PCM devices is presented in this article, which underlies perusing and composition activities. Consequently, we offered novel PCM devices and materials. Therefore, the total study is qualitative, and no machine learning approach is used. Because of this, we cannot say that the data is quantitative. Our work includes both test representations of the specific features observed in nanoscale PCM devices and material science demonstrations. In the end, we provide a point of view on some remaining open inquiries and possible future exploration directions.
