High-Temperature Materials in Ammonia/Hydrogen Gas Turbines
This entry reviews the critical role of material selection and design in ensuring efficient performance and safe operation of gas turbine engines fuelled by ammonia–hydrogen. As these energy fuels present unique combustion characteristics in turbine combustors, the identification of suitable materials becomes imperative. Detailed material characterisation is indispensable for discerning defects and degradation routes in turbine components, thereby illuminating avenues for improvement. With elevated turbine inlet temperatures, there is an augmented susceptibility to thermal degradation and mechanical shortcomings, especially in the high-pressure turbine blade—a critical life-determining component.

Fatigue and Workload Settings in Flight Operations
Conducting flight operations at the pace of air traffic relies on shift work, overtime work, work at night, work in different and numerous time zones, and unbalanced flight crew schedules. Such working hours and workload settings can cause disturbances of the circadian rhythm and sleep disorders among flight crew members; this can result in fatigue and can have an impact on the safety of flight operations. Fatigue impacts many cognitive abilities such as vigilance, memory, spatial orientation, learning, problem solving, and decision making. In aviation, fatigue has been identified as a hazard to the safety of flight operations.

Hydrogen-Assisted Aging Applied to Storage and Sealing Materials
Hydrogen is a possible alternative to fossil fuels in achieving a sustainable energy future. Unlike other, older energy sources, the suitability of materials for storing, distributing, and sealing systems in a hydrogen environment has not been comprehensively studied. Aging, the extended exposure of a material to an environmental condition, with hydrogen causes degradation and damage to materials that differ from other technologies. Improved understanding of the physical and chemical mechanisms of degradation due to a gaseous hydrogen atmosphere allows to better select and develop materials that are best suited to carrier and sealing applications. Damage to materials from aging is inevitable with exposure to high-pressure hydrogen.

Large-Scale Service Function Chaining in Smart City
Smart cities leverage the Internet of Things (IoT) to collect data from various sources and employ data-driven approaches to improve the management, evaluation, and decision-making processes. From a core network perspective, service function chaining (SFC) is an enabling paradigm for elastically controlling the massive network services (NS) from IoT-empowered smart cities. SFC can effectively enforce policies and regulations set by city authorities, including data retention policies, content filtering, compliance checks, etc. Moreover, SFC optimizes service delivery, resource efficiency, quality of experience (QoE)/quality of service (QoS), and service-specific routing. To activate all the beneficial factors, mobile network operators need solutions to reflect SFC orchestration policies while ensuring efficient resource utilization and preserving QoS in large-scale networking congestion states.
