The energy economy is experiencing a shift away from oil and gas sources as European nations and states, such as California, impose legislation on utilization and sourcing. A primary, would-be displacer of natural gas in the utility space is hydrogen (or chem + hydrogen hybrid fuels). In most cases, the preference of industry would be...

Polymer properties can permanently change as they age, which can lead to unexpected failures. These failures can be avoided by considering the polymer’s response to the environment during early product design. Liquids, gases, heat, and irradiation can have irreversible chemical effects on a polymer. Alternatively, in some cases the polymer can affect the liquid’s properties....

Robotic arc directed energy deposition (DED) additive manufacturing (AM) offers maximum build volume for building structures, adding features to structures, and repairing structures. The technical requirements for metal DED builds are similar to welding requirements. For example, the pending NAVSEA Technical Publication - Process Requirements for Metal Directed Energy Deposition Additive Manufacturing1 will specify maximum...
