LiVO3/LiZnVO4 Nanocomposite: High Performance Electrocatalyst for Ambient Nitrogen Reduction to Ammonia

open access: yesAdvanced Engineering Materials, EarlyView.
Lithium‐mediated electrocatalysis enables sustainable N2 fixation but hindered by parasitic Li deposition. An oxide‐oxide nanocomposite (LiVO3/LiZnVO4) structurally integrates lithium into active sites, suppressing plating and enhancing N2 activation and HER supression.

Direct Recycling of Cold Work Tool Steel Swarf into New Cutting Disks via Field‐Assisted Sintering

open access: yesAdvanced Engineering Materials, EarlyView.
Through a sintering method known as field‐assisted sintering technology/spark plasma sintering, cold work tool steel swarf can be directly recycled into new cutting disks. This method is capable of densifying the unconventional powder morphology of swarf, and it can also seal grinding contaminants, such as Al2O3, into the steel matrix.

On the kinetics of oxidation of austenitic stainless steels AISI 304 and incoloy 800H [PDF]

open access: yes, 1987
The interaction of oxygen with clean surfaces of stainless steels has been studied by spectroscopic ellipsometry and AES. The reaction involves chemisorption and dissolution of oxygen into the surface of the metal via a place-exchange mechanism.

Is Young's Modulus a Critical Coating Property Determining Fouling‐Release Performance of Marine Coatings?

open access: yesAdvanced Engineering Materials, EarlyView.
The release of foulers from protective marine coatings is determined by several interrelated material properties, including the strength of Young's modulus, the flexibility of chain segments, the surface free energy, and the magnitude of hydrodynamic stress.
