Materials and Corrosion, Volume 75, Issue 12, Page 1583-1599, December 2024.Hot corrosion is encountered in turbine engines, where Co‐based superalloys are proposed to replace Ni‐based materials. In the present study, the hot corrosion resistance of γ/γ′ superalloys of the Co–Ni–Al–W alloys was increased by their Co and W content.

Oxidation behavior of titanium aluminides
Le Journal de Physique IV, 1993 Results from an ongoing study of the high temperature oxidation of intermetallic compounds in the Ti-Al system are presented. The oxidation behavior of alloys based on TiAl (γ) has been found to be extremely complex depending on temperature and atmosphere composition.

Knudsen effusion mass spectrometry: Current and future approaches
Rapid Communications in Mass Spectrometry, Volume 38, Issue 14, 30 July 2024.Rationale Knudsen effusion mass spectrometry (KEMS) has been a powerful tool in physical chemistry since 1954. There are many excellent reviews of the basic principles of KEMS in the literature. In this review, we focus on the current status and potential growth areas for this instrumental technique.

Advanced Engineering Materials, Volume 26, Issue 14, July 2024.Powder hot extrusion and heat treatment of titanium metal matrix composite's lead to high specific stiffnesses of 34.6 GPa cm3 g−1. Remelting, to simulate an additive manufacturing method, of these materials results in severe changes of the microstructure and a decrease in the mechanical properties even with ex situ reinforcements.

Enhanced Electrocatalytic Conversion of Nitrates to Ammonia: Fuel from Waste
ChemSusChem, Volume 17, Issue 10, May 21, 2024.A flow‐through membrane‐free electrocatalytic device (CMED) producing NH3 from nitrate (NO3−) is developed aiming at converting waste to fuel. The combination of NO3− reduction and hydrogen ion (H+) generating catalysts (indium‐palladium (In−Pd)) and platinum (Pt)) enhances conversion rates, reduces by‐products, and stabilizes energy consumption.
