On the One-dimensional Stability of Viscous Strong Detonation Waves [PDF]

, 2003
Building on Evans function techniques developed to study the stability of viscous shocks, we examine the stability of viscous strong detonation wave solutions of the reacting Navier-Stokes equations.

Biocarbon Suitability Evaluation for Direct Injection in Blast Furnace Ironmaking

steel research international, Volume 97, Issue 4, Page 2278-2287, April 2026.
This study examines densified biocarbon for direct injection in blast furnace ironmaking to reduce greenhouse gas (GHG). Enhanced burnout performance, along with favorable reactivity and carbon structure of the combustion residue, supports its suitability for blast furnace injection. Modeling results indicate that up to a 27% reduction in GHG emissions

The Future of Hydrogen‐Powered Aviation: Technologies, Challenges, and a Strategic Roadmap for Sustainable Decarbonization

Advanced Energy and Sustainability Research, Volume 7, Issue 3, March 2026.
Hydrogen‐powered aviation offers a transformative pathway to zero‐emission flight by eliminating in‐flight CO2 emissions. Key considerations include propulsion systems (fuel cells and hydrogen combustion), cryogenic storage and insulation challenges, infrastructure and cost barriers, and supply‐chain constraints.

Valorization of fishing industry by‐products for biodiesel production: Unlocking the potential of residual fish oil

Biofuels, Bioproducts and Biorefining, Volume 20, Issue 2, Page 1111-1141, March/April 2026.
Abstract Fishing waste and its by‐products, whether naturally occurring or generated by the processing industry, represent a significant opportunity for producing high‐value products. These often discarded or underutilized residues can be converted into various valuable products through advanced processing technologies. Among the potential products are

A predictive model of natural gas mixture combustion in internal combustion engines

Ingeniería e Investigación, 2007
This study shows the development of a predictive natural gas mixture combustion model for conventional com-bustion (ignition) engines. The model was based on resolving two areas; one having unburned combustion mixture and another having combustion ...

Tuning Ce‐Zr‐Al Mixed Oxide Supports to Enhance Pt‐Pd Catalyst Performance for Low‐Temperature CO and C3H6 Oxidation in Diesel Emissions

ChemCatChem, Volume 18, Issue 5, 13 March 2026.
ABSTRACT Diesel oxidation catalysts (DOCs) with low‐temperature activity are required for low‐temperature combustion diesel (LTC‐D) engine technologies to meet emission regulations. To probe the impact of oxygen availability on activity, bimetallic Pt‐Pd catalysts supported on Ce‐Zr‐Al mixed oxides with varying Ce/Zr/Al contents were systematically ...
