Nanocubes and Cuboctahedra: Entropic Stabilization Versus Thermal Segregation in Rock Salt‐ and Spinel‐Type Multinary Oxides from Spray‐Flame Synthesis

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Spray‐flame synthesis enables highly flexible and scalable production of multinary and high‐entropy oxide nanoparticles due to high synthesis temperatures with subsequent quenching. Temperature‐dependent in situ diffraction of as‐synthesized materials clearly reveals entropy stabilization in rock salt lattices, while spinels—featuring tetrahedral and ...

Toward a Paradigm Shift in Low‐Temperature SCR Catalyst Design: Defect Engineering and Data‐Driven Integration

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This work systematically reviews the key factors influencing the performance of low‐temperature NH3‐SCR. The mechanism and challenges of defect engineering strategies, such as oxygen vacancies, heteroatom doping, crystal facet exposure, and surface reconstruction, in controlling both activity and selectivity were analyzed.

Flow Characteristics in Cylindrical Combustion Chamber

Journal of Engineering and Sustainable Development, 2005
Combustion equipment of turbulent flows has usually been developed empirically, with only qualitative guidance from theory. The reason is that, although has relevant processes have long been understood qualitatively, no accurate and economical procedure

Evaluation of the Local Burning Velocity Using DNS Data of Turbulent Premixed Flames [PDF]

, 2014
The local burning velocity, which is based on the consumption rate of the unburned mixture, is one of the dominant parameters in turbulent premixed flames. In this study, the evaluating method of the local burning velocity was investigated using DNS data

Governing Positive Energy Districts: The Role of Legitimation and Identity Across Residential and Industrial Contexts

Environmental Policy and Governance, EarlyView.
ABSTRACT Increasing electricity demand from data centres, industrial applications, electric vehicles and domestic heating is creating pressure to develop electricity systems in many parts of the world, but especially in Western countries. In response to challenges such as grid congestion, interconnection queues and climate‐related hazards, network ...

DNS Analysis on the Indirect Relationship between the Local Burning Velocity and the Flame Displacement Speed of Turbulent Premixed Flames [PDF]

, 2014
The local burning velocity and the flame displacement speed are the dominant properties in the mechanism of turbulent premixed combustion. The flame displacement speed and the local burning velocity have been investigated separately, because the flame ...

Constructing Policy (In)coherence in Germany's Energy Transition and Impacts on (In)equality

Environmental Policy and Governance, EarlyView.
ABSTRACT Policy coherence is widely regarded as essential for achieving sustainable development, climate targets, and reducing inequality, as reflected in the 2030 Agenda for Sustainable Development. Recent scholarship has moved beyond technocratic approaches, drawing on comparative politics, particularly the “3 I's” of ideas, interests, and ...
