CO2‐Based Fischer‐Tropsch Synthesis Toward Aviation Fuel Components Using a Na‐Promoted Fe Catalyst

Chemie Ingenieur Technik, Volume 97, Issue 5, Page 508-517, May 2025.
A Na‐promoted Fe catalyst was investigated to produce liquid hydrocarbons using CO2‐based Fischer‐Tropsch synthesis. As a result of a systematic variation of operation parameters, 49 wt % of the organic liquid was promising as sustainable aviation fuel. Abstract The CO2‐based Fischer‐Tropsch synthesis toward liquid hydrocarbons was investigated using a

Predicting rare events using training data from stratified sampling designs, with application to human‐caused wildfire prediction

Canadian Journal of Statistics, EarlyView.
Abstract Response‐based sampling is often used in modelling rare events from large, imbalanced data for efficiency. When modelling the event with logistic regression, the sampling design may be adjusted for using sampling weights or an offset. We propose a stratified sampling design for modelling rare events with large data which improves on previous ...

Proximity Strategies for Stakeholder Engagement in Business Models for Sustainability: A Conceptual Framework

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Stakeholder engagement is a crucial part of business models for sustainability (BMfS), but companies struggle to implement it. One approach that could be leveraged is the concept of proximity, as it can enable sharing of knowledge and values.

Electrified Dynamically Responsive Ammonia Decomposition to Hydrogen Based on Magnetic Heating of a Ru Nanocatalyst

ChemSusChem, Volume 18, Issue 8, April 14, 2025.
Almost instantaneous decomposition of ammonia to hydrogen and nitrogen is achieved by magnetic heating of the catalyst. The dynamically fast response of the reactor enables the utilization of intermittent, renewable electrical energy for the on‐demand release of hydrogen, an important energy vector.
