Summary of ECE Presentations at EC-18

EPJ Web of Conferences, 2015
There were nine ECE and one EBE presentation at EC-18. Four of the presentations were on various aspects of ECE on ITER. The ITER ECE diagnostic has entered an important detailed preliminary design phase and faces several design challenges in the next 2 ...

Impacts of refining Canadian partially upgraded bitumen: Fluid catalytic cracking

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract In this study, we examine the fluid catalytic cracking (FCC) performance of vacuum gas oil (VGO) from partially upgraded bitumen (PUB), a novel refinery feedstock from Canadian bitumen. FCC experiments were conducted in a lab‐scale FCC unit with VGOs from two different PUBs prepared using thermal cracking and solvent deasphalting, along with ...

Temperature‐Dependent Kinetics of Plasma‐Based CO2 Conversion: Interplay of Electron‐Driven and Thermal‐Driven Chemistry

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
The transformation of CO2 into chemical building blocks is essential for a net‐zero energy future. Plasma‐chemical processing offers promising potential to achieve this. Here, we explore a temperature‐dependent plasma‐chemical reaction mechanism, revealing a shift from electron‐driven to thermal‐driven CO2 conversion regimes.

SOLPS-ITER modeling of the ITER far scrape-off layer with realistic wall geometry

Nuclear Fusion
For the first time with the SOLPS-ITER code (using the recently released ‘Wide Grids’ code version 3.2.0), plasma boundary modeling with numerical grids extending to all main chamber surfaces under Q = 10 burning plasma conditions has been performed ...

A midsize tokamak as a fast track to burning plasmas

AIP Advances, 2011
This paper describes the conceptual design of a midsize tokamak as a fast track to the investigation of burning plasmas. It is shown that it could reach large values of energy gain (≥ 10) with only a modest improvement in confinement over the scaling ...

Ni–Pd Catalytic Synergy on Rod‐Shaped CeO2 for Boosting Low‐Temperature CH4 Oxidation

EcoEnergy, EarlyView.
Introducing Ni into Pd/CeO2 markedly accelerates deep CH4 oxidation by inducing a synergistic interaction between Ni and Pd species. This synergistic effect significantly improves low‐temperature activity and long‐term stability, providing a rational strategy for efficient CH4 abatement over Pd‐based catalysts under lean CH4 conditions while reducing ...
