Breaking Methane without Metals: Induction‐Heated Carbon Catalyst at Low‐Temperature Process
Advanced Energy and Sustainability Research, Volume 7, Issue 3, March 2026.The catalytic decomposition of methane (or biomethane) into hydrogen with direct carbon capture, with high promising catalytic performance, was achieved using a carbon‐based catalyst coupled with electromagnetic induction heating. The results confirm that the reaction is carried out by catalysis assisted by defects present on the carbon surface, which ...

Stability and Instability of Time‐Domain Boundary Element Methods for the Acoustic Neumann Problem
Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 1, March 2026.ABSTRACT This work presents a stable time‐domain boundary element method for the acoustic wave equation in three‐dimensional unbounded domains. Other formulations of time‐domain boundary element methods based on retarded potential operators are known to exhibit stability issues, which often hinder their use in industrial contexts.

Substructuring of a Petrol Engine: Dynamic Characterization and Experimental Validation
Applied Sciences, 2019 In this work, the vibration behavior of a 4-cylinder, 4-stroke, petrol engine was simulated by leveraging on the Finite Element Method (FEM). A reduced modelling strategy based on the component mode synthesis (CMS) was adopted to reduce the size of the ...

On adaptive minimax density estimation on $R^d$
, 2013 We address the problem of adaptive minimax density estimation on $\bR^d$ with $\bL_p$--loss on the anisotropic Nikol'skii classes. We fully characterize behavior of the minimax risk for different relationships between regularity parameters and norm ...

Australian Economic Review, Volume 59, Issue 1, Page 5-15, March 2026.ABSTRACT The Australian economy grew at a moderate pace in 2024–2025. Monetary policy gradually eased through 2025, with three rate cuts bringing the cash rate down to 3.6%. The labour market has softened further from its post‐pandemic state, but a resurgence of inflation in recent months places further monetary easing in doubt.
