“…AM and other advanced manufacturing processes are being looked to by the nuclear energy industry to shorten production schedules, save prices, and provide design flexibility for the components of nuclear power plants [98]. AM is a relatively recent field of study for nuclear energy, although other technologies, including powder metallurgy (more especially, hot isotactic pressing), are more developed for nuclear energy components [99,100]. It is also applied for fuel cells, such as biological fuel cells, polymer electrolyte, reversible, and micro fuel cells.…”

Additive manufacturing (AM), commonly known as 3D printing, has garnered significant attention across various industries for its flexibility and simplicity in fabrication. This review explores the evolution of AM technologies, encompassing rapid prototyping and 3D printing, which have revolutionized conventional manufacturing processes. The paper discusses the transition from rapid prototyping to AM and highlights its role in creating fully customized products, optimizing topologies, and fabricating complex designs, especially in the aerospace, medical, automotive, defense energy and food industries. The study delves into the fundamental principles of 3D and 4D printing technologies, detailing their processes, materials, and applications. It provides an overview of the various AM techniques, such as Vat photopolymerization, powder bed fusion, material extrusion, and directed energy deposition, shedding light on their classifications and applications. Furthermore, the paper explores the emergence of 4D printing, which introduces an additional dimension of “time” to enable dynamic changes in printed structures. The role of AM in different industries, including aerospace, medical, automotive, energy, and Industry 4.0, is thoroughly examined. The aerospace sector benefits from AM's ability to reduce production costs and lead times, while the medical field leverages bioprinting for synthetic organ fabrication and surgical equipment development. Similarly, AM enhances flexibility and customization in automotive manufacturing, energy production, and Industry 4.0 initiatives Overall, this review provides insights into the growing significance of AM technologies and their transformative impact on various industries. It underscores the potential of 3D and 4D printing to drive innovation, optimize production processes, and meet the evolving demands of modern manufacturing.

Hydrogen (H2) gas, with its high calorimetric combustion energy and cleanness, is a green source of energy and an alternative to fossil fuels. However, it has a small kinetic diameter, with high diffusivity and a highly explosive nature. Hence, the reliable detection of H2 gas is essential in various fields such as fuel cells. Herein, we decorated ZnO nanoparticles (NPs) with Pd noble metal NPs, using UV irradiation to enhance their H2 gas-sensing performance. The synthesized materials were fully characterized in terms of their phases, morphologies, and chemical composition. Then, the sensing layer was deposited on the electrode-patterned glass substrate to make a transparent sensor. The fabricated transparent gas sensor was able to detect H2 gas at various temperatures and humidity levels. At 250 °C, the sensor exhibited the highest response to H2 gas. As a novelty of the present study, we successfully detected H2 gas in mixtures of H2/benzene and H2/toluene gases. The enhanced H2 gas response was related to the catalytic effect of Pd, the formation of heterojunctions between Pd and ZnO, the partial reduction of ZnO to Zn in the presence of H2 gas, and the formation of PdHx. With a high performance in a high response, good selectivity, and repeatability, we believe that the sensor developed in this study can be a good candidate for practical applications where the detection of H2 is necessary.
