Dry Reforming of Methane Over Ceria Supported Catalysts Produced by Direct Impregnation with Leachate Solution from Spent Diesel Auto‐Catalysts

ChemCatChem, Volume 17, Issue 22, November 24, 2025.
The Pt‐containing leachate solution obtained by a hydrometallurgical recovery route of spent diesel oxidation catalysts was successfully used to fabricate Pt/CeO2 catalysts. Dry reforming of methane and reverse water gas shift tests showed good conversion efficiencies, with negligible carbon deposition after ToS experiments of several hours.

Terminal weight and constraint design for wave energy converter economic model predictive control problems

International Journal of Robust and Nonlinear Control, Volume 35, Issue 7, Page 2694-2716, 10 May 2025.
Abstract The wave energy converter (WEC) control problem aims to make the best use of wave excitation to maximize energy capture and ensure safe operation across a broad range of sea states. This falls into the recently developed economic model predictive control (EMPC) framework, subject to wave excitation being treated as a predictable additive ...

Evaluating Vehicle‐Borne and Person‐Worn Spray Technologies to Deliver Target Decontaminant Doses to Urban Surfaces for Biological Remediation

Remediation Journal, Volume 35, Issue 2, Spring 2025.
ABSTRACT The remediation of urban infrastructure contaminated with an environmentally persistent pathogen requires a large proportion of surfaces to be treated with liquid‐based biocides. Critical to this wide area decontamination effort, will be logistically viable approaches that apply target quantities of formulation to these surfaces while ensuring
