steel research international, Volume 97, Issue 4, Page 2241-2249, April 2026.Cold spray deposition of stainless steel (grade: SS304) is evaluated for marine applications, with emphasis on martensitic transformation during impact. Analytical modeling, simulations, and experiments reveal that helium‐assisted spraying of fine powders promotes cooling below the martensitic start temperature, enabling up to ≈40% austenite to ...

The Monetary Policy–Commodities Nexus: A Survey
Journal of Economic Surveys, Volume 40, Issue 2, Page 1050-1082, April 2026.ABSTRACT This survey synthesizes evidence on the bidirectional links between commodity markets and monetary policy. On the commodities‐to‐policy side, we review how shocks to energy, food, and metals pass through to inflation, inflation expectations, economic activity, and financial stability in state‐dependent ways that vary by shock type, exposure ...
