“…[ 172 ] In addition, the lightweight design as the focus not only ensures the safety and effectiveness of structures but also reduces the energy consumption. [ 14 ] The specific strength (the ratio of strength to density) is an important indicator of lightweight design. For example, the introduction of light atoms (Ti, Al, Mg, and Li) in the BCC HEA not only ensures the strength but also effectively reduces the material density without changing the lattice structure.…”

The performances of high‐entropy materials (HEMs), including high‐entropy alloys, high‐entropy ceramics, and high‐entropy polymers, with unique characteristics (high mixing entropy, serious lattice distortion, and short‐range order) determined by experiments are out of the ordinary, such as the excellent mechanical properties. The important research methods on HEMs are briefly introduced from the physical modeling, multiscale simulation, and experiments at various scales. The microstructures (dislocation, twinning, grain boundary, and phase) and performances (mechanical property, physical property, chemical property, optical property, medical property, and irradiation property) are summarized. Future directions of research and development with a focus on modeling and simulation in HEMs are discussed. In the next, HEMs with the unique properties would be promising candidates for industrial applications beyond conventional alloys.

“…Elsewhere, there are opportunities to overcome the compositional barriers to increased recycling of discarded products by designing more recycling-friendly alloys. Research avenues here include assessing the opportunity to use a smaller set of parent alloys with a greater focus on using thermomechanical processing (rather than compositional changes) to tune mechanical properties [263].…”

Society's consumption of natural resources and the impact of industrial activities on the environment has gained increasing attention over the last several decades. This paper provides a historical perspective on the origins of the environmental movement and its connection to industrial systems. Then, recent research related to product design, process improvement and change, green manufacturing planning, and the circular economy are described. With respect to product design, topics such as material selection and component light-weighting are considered. For process-related research, efforts such as operation changes and equipment design for reduced energy consumption are discussed. For manufacturing planning, new developments in process planning and production scheduling are highlighted that consider environmental performance. The concept of circular economy is examined critically, with particular emphasis placed on closing materials loops via recycling and remanufacturing. The paper concludes with a discussion of challenges and opportunities to achieve the goal of industrial sustainability.

“…Whether in personal or local bubbles as a consequence of algorithms of data science in media content, or within a chemical purification process, there seems to be an element of "bias" involved in these filter operations. This inherent bifurcation quality of filtering operations manifests themselves in many of today's challenges; from the filter bubbles, personalized news feeds, or data-driven insurance policies [4,5,76], to a race to optimized functions through a fetish of material purity accounting to a major material sustainability [108]. It is crucial that the function and consequences of this separatory aspect be regularly noted and checked.…”

This works aims to re-investigate different aspects of a variety of filters and filtration processes within diverse realms of knowledge from an interdisciplinary point of view, and develop a comprehensive Active Model of Filter that accommodates the phenomena in its entire diversity and complexity. The Active Filter Model proposes to take Filter—from various fields and scales operating at material and symbolic level—not as mere objects, but as difference-producing phenomena that need to be addressed as complex active systems within event-based boundaries. The model underlines a systemic, operative, performative, and negentropic nature to the phenomena that invites one to; recognize various elements and intra-actions within a filter system; follow chains of operations and processes that render the activity; take the performative and ecology building aspect of the filter activity into consideration; and acknowledge the negentropic, order-producing nature of filtering phenomena. The Active Filter Model is meant to serve as a foundation for further analysis and synthesis in various fields dealing with Filter, and the research approach is put forward as a paradigm for how seemingly disciplinary concepts such as Filter can be rethought through interdisciplinary methods, and mutually complement research questions within active matter, biology, information philosophy, data science and sustainability discourses.
