Coated particle fuel: Historical perspectives and current progress

Fabrication and characterization of fully ceramic microencapsulated fuels

As an extraordinarily lightweight and porous functional nanomaterial family, aerogels have attracted considerable interest in academia and industry in recent decades. Despite the application scopes, the modest mechanical durability of aerogels makes their processing and operation challenging, in particular, for situations demanding intricate physical structures. “Bottom-up” additive manufacturing technology has the potential to address this drawback. Indeed, since the first report of 3D printed aerogels in 2015, a new interdisciplinary research area combining aerogel and printing technology has emerged to push the boundaries of structure and performance, further broadening their application scope. This review summarizes the state-of-the-art of printed aerogels and presents a comprehensive view of their developments in the past 5 years, and highlights the key near- and mid-term challenges.

3D printing of high-purity silicon carbide

A novel approach to fabricating fuel compacts for the next generation nuclear plant (NGNP)

Architecture and properties of TCR fuel form

Disclosed are examples of an apparatus for cooling a barrel 12 of a firearm 10 and examples of a cooled barrel assembly 32 for installation into an existing firearm 10. When assembled with the barrel 12, a contact surface 16 of a shell 14 is proximate to, and in thermal communication with, the outer surface of the barrel 18. The shell 14 is formed of commercially available or modified graphite foam.

A fuel cell unit (50) includes an array of solid oxide fuel cell tube sheets (10) having porous metallic exterior (11) surfaces, interior fuel cell layers (12, 13, 14), and interior surfaces, and at least one header in operable communication with the array of solid oxide fuel cell tube sheets (10) for directing a first reactive gas into contact with the porous metallic exterior surfaces and for directing a second reactive gas into contact with the interior surfaces. The header also includes at least one busbar selected from the group consisting of an exterior busbar (124) disposed in electrical contact with the porous metallic exterior surfaces and an interior busbar (132) disposed in electrical contact with the interior surfaces.
