Fibre Composite Manufacturing Technologies in Shipyards Industry
Fibre-reinforced polymers (FRPs) are one of the most attractive materials for engineering application. In recent times, fibrous composites have become a strong alternative to steel in the construction industry. The general advantages of FRP compared to conventional materials include high durability, cost-effective fabrication, excellent resistance to corrosion, fatigue, and fire, lighter weight, and lower maintenance costs. Owing to their unique properties, FRP composites can be successfully used in the automobile, aerospace, and marine industry, especially for lightweight constructions.

Micro-Arc Oxidation in Titanium and Its Alloys
Titanium (Ti) and its alloys are widely recognized as preferred materials for bone implants due to their superior mechanical properties. However, their natural surface bio-inertness can hinder effective tissue integration. To address this challenge, micro-arc oxidation (MAO) has emerged as an innovative electrochemical surface modification technique. Its benefits range from operational simplicity and cost-effectiveness to environmental compatibility and scalability. Furthermore, the distinctive MAO process yields a porous topography that bestows versatile functionalities for biological applications, encompassing osteogenesis, antibacterial, and anti-inflammatory properties.

Spatial Planning and Energy Efficiency in Urban Form
As the urban population grows, so does their energy consumption, making efficiency critical to mitigate emissions and resource use. Thus, spatial and transport planning must include energy efficiency and their strategies, as these are vital to urban sustainability. In this sense, compactness has been shown to have many positive aspects that serendipitously go much in line with Jacobs’ ideas. The urban environment is expected to host a growing number of dwellers in the coming decades, and compact urbanism is one possible solution to keep energy consumption under control while providing all the benefits of proximity.

Hybrid Membrane Distillation Systems
Membrane distillation (MD) is an attractive separation process that can work with heat sources with low temperature differences and is less sensitive to concentration polarization and membrane fouling than other pressure-driven membrane separation processes, thus allowing it to use low-grade thermal energy, which is helpful to decrease the consumption of energy, treat concentrated solutions, and improve water recovery rate.

Development of Port Communication Systems
The efficient and sustainable operation of container terminals (CTs) plays a key role in global trade and in ensuring the sustainable functioning of transport chains. While larger container terminals utilise port communication systems (PCSs), smaller container terminals often face challenges when implementing similar systems due to resource constraints and unique operational characteristics.

Criteria for the Adoption of Sustainable Maintenance Practice
The evolution from traditional industrial maintenance to sustainable maintenance (SM) is pivotal within the existing industrial ecosystem. It represents a critical transition towards integrating sustainability principles into maintenance practices including environmental, social and economic outcomes. Increasingly focused on SM, the importance of understanding the impact of environmental initiatives and sustainability indicators becomes a focal point. However, the paradigm shift of SM is lagging in the industrial ecosystem. Although it marked a growing interest in the academic community, the lack of empirical studies and practical implications of adopting SM has been reported. Based on the Bayesian analysis, and the bibliometric and thematic analyses, the role of digital technologies in enhancing SM practices highlights the potential pathways for easier transition and applicability of sustainability-related maintenance practices.

Distributed Propulsion for Next-Generation Aircraft
Developments in the design of transport aircraft are increasingly focusing on the search for innovative solutions to improve general performance and reduce the environmental impact of flight operations. In this context, specific attention is being devoted to research into non-conventional solutions for the integration of the propulsion system, involving two different interconnected technological threads. From a general point of view, new types of propulsion systems are under investigation, and technologies involving new fuels, such as hydrogen or sustainable aviation fuels, or electric and hybrid-electric powertrains, are under development to provide breakthrough forward advancements in the field. In addition to these important innovations, and in a way that is generally complementary, non-conventional powertrain/airframe integrations are increasingly being investigated since, either as standalone or in combination with previous new power supply concepts, they can contribute to general improvements in aircraft performance, with significant implications for reducing environmental impact. Among the advanced technologies under investigation, it is worth mentioning distributed propulsion, which is gaining much interest, especially in the context of synergistic integration with electric powertrains.
