“…Relatively, to obtain a homogeneous distribution and dispersion of nanofillers within the matrix, relatively high grinding energy is required. Wet milling is less effective due to the presence of a solvent, while high-energy milling during dry milling can reduce the crystal size [130,131]. and subsequently cold welded into particles.…”

In the pursuit of achieving zero emissions, exploring the concept of recycling metal waste from industries and workshops (i.e., waste-free) is essential. This is because metal recycling not only helps conserve natural resources but also requires less energy as compared to the production of new products from virgin raw materials. The use of metal scrap in rapid tooling (RT) for injection molding is an interesting and viable approach. Recycling methods enable the recovery of valuable metal powders from various sources, such as electronic, industrial, and automobile scrap. Mechanical alloying is a potential opportunity for sustainable powder production as it has the capability to convert various starting materials with different initial sizes into powder particles through the ball milling process. Nevertheless, parameter factors, such as the type of ball milling, ball-to-powder ratio (BPR), rotation speed, grinding period, size and shape of the milling media, and process control agent (PCA), can influence the quality and characteristics of the metal powders produced. Despite potential drawbacks and environmental impacts, this process can still be a valuable method for recycling metals into powders. Further research is required to optimize the process. Furthermore, ball milling has been widely used in various industries, including recycling and metal mold production, to improve product properties in an environmentally friendly way. This review found that ball milling is the best tool for reducing the particle size of recycled metal chips and creating new metal powders to enhance mechanical properties and novelty for mold additive manufacturing (MAM) applications. Therefore, it is necessary to conduct further research on various parameters associated with ball milling to optimize the process of converting recycled copper chips into powder. This research will assist in attaining the highest level of efficiency and effectiveness in particle size reduction and powder quality. Lastly, this review also presents potential avenues for future research by exploring the application of RT in the ball milling technique.

This experimental study used recycled copper chips as a base material for electrode manufacturing through the additive manufacturing route utilizing the bound powder extrusion (BPE) process. Initially, the copper chips were collected from a conventional machining centre. Then, the chip size was reduced by the two-step milling process (ball-to-powder ratio, 2:1) to attain the micro-sized fine particles around 44 μm, which is the prerequisite for preparing the base material for the BPE process. Subsequently, the input parameters were optimized to a layer thickness of 0.125 mm, nozzle diameter of 1 mm, and printing speed of 20 mm/s by the Box-Behnken design approach and attained a maximum relative density of 98.57%. Finally, the BPE-recycled copper tool electrode was manufactured in 0° and 90° orientations. Further, the electrical conductivity of the tool, material removal rate, tool wear rate, and surface roughness of the machined surface of manufactured components were evaluated and compared for BPE-90°, BPE-0°, and conventional tools. The result shows that the BPE-90° tool electrode performs better than BPE-0° and conventional tools.

“…By modifying the experimental parameters (e.g., temperature, stabilizing agent, or reducing agent) investigated so far, significant structural and morphological differences were induced and thus, the photocatalytic activity of the semiconductors could be increased [ 11 ]. The morphology [ 12 ], optical properties [ 13 , 14 , 15 ], crystal structure [ 16 , 17 ], and applicability [ 18 , 19 ] of semiconductors can also be controlled by varying the previously listed synthesis parameters.…”

In the present work, shape tailored Cu2O microparticles were synthesized by changing the nature of the reducing agent and studied subsequently. d-(+)-glucose, d-(+)-fructose, d-(+)xylose, d-(+)-galactose, and d-(+)-arabinose were chosen as reducing agents due to their different reducing abilities. The morpho-structural characteristics were studied by X-ray diffraction (XRD), scanning electron microscopy (SEM), and diffuse reflectance spectroscopy (DRS), while their photocatalytic activity was evaluated by methyl orange degradation under visible light (120 min). The results show that the number of carbon atoms in the sugars affect the morphology and particle size (from 250 nm to 1.2 µm), and differences in their degree of crystallinity and photocatalytic activity were also found. The highest activity was observed when glucose was used as the reducing agent.
