Bis(2‐Adamantyl)Magnesium: Synthesis, Structure, and Applications of a Versatile and Shelf‐Stable 2‐Adamantyl Anion Equivalent

Chemistry – A European Journal, EarlyView.
At last, the long‐sought bis(2‐adamantyl)magnesium reagent has been prepared in high yield as a stable tetrahydrofuran/dioxane adduct and fully characterized by x‐ray crystallography. This potent nucleophile outperforms the corresponding Grignard in transmetallation and carbonyl addition reactions, opening new avenues in adamantyl organometallic and ...

Silver‐Mediated Deuterium Labelling of Quinones and Related Compounds by Hydrogen Isotope Exchange With D2O

Chemistry – A European Journal, EarlyView.
A new silver‐catalyzed H/D exchange reaction was developed for the labelling of quinones and related compounds. Both homogeneous and heterogeneous catalytic processes were implemented using heavy water as a simple deuterium source. The corresponding deuterated compounds were obtained with high isotopic enrichment through a practical method that opens ...

Econometric modeling of ocean eddy kinetic energy and Atlantic Meridional Overturning Circulation transport with implications for Sustainable Development Goal 14

Frontiers in Environmental Economics
The United Nations Sustainable Development Goal 14 has emphasized conservation efforts for oceans especially in the wake of climate change. Because sea surface temperatures and sea water turbulence have been increasing, this article modeled the ...

Toward an Energetically Consistent, Resolution Aware Parameterization of Ocean Mesoscale Eddies

Journal of Advances in Modeling Earth Systems, 2019
A subgrid‐scale eddy parameterization is developed, which makes use of an explicit eddy kinetic energy budget and can be applied at both “non‐eddying” and “eddy‐permitting” resolutions.

Impacts of ocean current–atmosphere interactions on mesoscale eddy energetics in the Kuroshio extension region

Geoscience Letters, 2020
The surface ocean current’s imprint on the wind stress (known as the current feedback) has a significant influence on the wind power input to the ocean. In this study, we investigate the effect of the current feedback on mesoscale eddy energetics in the ...

Review of CFD modelling techniques for single‐phase and multiphase flow in static mixers

The Canadian Journal of Chemical Engineering, EarlyView.
This review synthesizes computational fluid dynamics (CFD) approaches for static mixers, linking hydrodynamics to pressure drop, particle/droplet distributions, mixing metrics, and heat‐transfer performance to guide modelling choices and design decisions. Abstract Static mixers enable compact and low‐energy intensification.

Preventing wall deposition in duct flows: The role of particle number density and flow direction

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Particle deposition in wall‐bounded turbulent flows is a challenge in many industries, including pneumatic conveying, filtration, and related applications. When particles accumulate near boundaries, they reduce transport efficiency, alter near‐wall flow structures, and cause blockage.

Synthesis and characterization of polymer networks obtained by conventional radical and RAFT copolymerization processes in supercritical carbon dioxide

The Canadian Journal of Chemical Engineering, EarlyView.
Conventional and RAFT dispersion copolymerizations of HEMA and EGDMA in supercritical CO2 are compared in terms of swelling index (crosslink density), morphology, particle size distribution, and modular differential scanning calorimetry. Abstract The syntheses of net‐poly((2‐hydroxyethylene methacrylate)‐co‐(ethylene glycol dimethacrylate ...

The Multi‐Scale Response of the Eddy Kinetic Energy and Transport to Strengthened Westerlies in an Idealized Antarctic Circumpolar Current

Geophysical Research Letters
The Southern Ocean's eddy response to changing climate remains unclear, with observations suggesting non‐monotonic changes in eddy kinetic energy (EKE) across scales.
