Carbon Energy, EarlyView.Here, we design a flexible and non‐flammable solid‐state electrolyte with hierarchical dual‐ion conductive channels. The engineered electrolyte combines continuous organic conductive‐phase pathways for fast bulk Li+ transport and dynamic polymer networks for interfacial ion hopping, achieving unprecedented room temperature conductivity (> 1 mS cm−1 ...

Alkali‐Metal Base Catalyzed Electrocyclization of Isoprene Derivatives
Chemistry – A European Journal, EarlyView.Simple and abundant alkali‐metal base catalysis in combination with Lewis basic polyamines enables the electrocyclization of isoprene‐derived trienes to cycloheptadienes under neat conditions. Mechanistic insight supported by DFT guides a scalable route to seven‐membered carbocycles which, after reduction, give saturated cycloalkanes relevant as ...

Environmental Impact of Silicic Magmatism in Large Igneous Province Events
Geophysical Monograph Series, Page 133-151., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Stability and Liftoff of a N2-in-H2 Jet Flame in a Vitiated Co-flow at Atmospheric Pressure
Eurasian Chemico-Technological Journal, 2014 The stability and liftoff characteristics of a nitrogen (N2) diluted hydrogen (H2) jet flame in a vitiated co-flow are investigated experimentally with particular attention focused on regimes where multiple stabilization mechanisms are active ...

Global and Detailed Calculation of Tube Wall Temperature in a Process Furnace Steam Superheater
Chemie Ingenieur Technik, EarlyView.This study presents a comparison between an iterative global model and multiple approaches to a new non‐iterative model with the purpose of predicting tube wall temperature of a superheater. The results show that the non‐iterative method achieves sufficient accuracy while improving the prediction of local temperature distribution and better ...

Flame Stabilisation Mechanism for Under-Expanded Hydrogen Jets
FireA hydrogen under-expanded jet released from a high-pressure vessel or equipment into the atmosphere through a 0.53 mm diameter orifice results in a sustained lifted flame for pressures above 4 MPa and flame blow-out at pressures below 3 MPa. Knowledge of

The Canadian Journal of Chemical Engineering, EarlyView.Abstract Synthetic jet fuel containing non‐petroleum‐derived kerosene can be produced from synthetic kerosene obtained through processes that include a hydroprocessing step. The potential use of non‐sulphided (reduced) nickel supported on alumina (Ni/Al2O3) was evaluated as an alternative to sulphided catalysts to saturate alkenes in sulphur‐free ...
