Sea ice dynamics in Foxe Basin: formation of a thick dirty seasonal ice cover along a proposed year-round shipping route

open access: yesArctic Science
Foxe Basin is a shallow inland sea in the Canadian Arctic that has strong tidal dynamics and is covered by a notoriously deformed and dirty sea ice cover for 9 months a year.

Enhancing Low‐Temperature Performance of Sodium‐Ion Batteries via Anion‐Solvent Interactions

open access: yesAdvanced Functional Materials, EarlyView.
DOL is introduced into electrolytes as a co‐solvent, increasing slat solubility, ion conductivity, and the de‐solvent process, and forming an anion‐rich solvent shell due to its high interaction with anion. With the above virtues, the batteries using this electrolyte exhibit excellent cycling stability at low temperatures. Abstract Sodium‐ion batteries

Electrospun Wood‐Derived Biopolymers as Electrodes in Electrochemical Energy Storage Technologies

open access: yesAdvanced Functional Materials, EarlyView.
Electrospinning transforms wood‐derived cellulose and lignin into architecturally defined, binder‐free carbon electrodes with tuneable porosity and functionality. This review shows how fibre design enables decoupled charge and mass transport, enhancing performance across battery systems, while identifying key challenges in spinnability, scalability ...

Assessing Arctic marginal ice zone dynamics from 1979 to 2023: insights into long-term variability and morphological changes

open access: yesEnvironmental Research Letters
Against the backdrop of global climate change, the continued decline in Arctic sea ice extent and thickness has intensified the dynamic evolution of the marginal ice zone (MIZ).

CO2‐to‐CO Conversion in a Gas‐Fed, Zero‐Gap, PEM Electrolyzer Enabled by Polycations and Nitrogen‐Doped Carbon‐Supported Cobalt Nanoparticles

open access: yesAdvanced Functional Materials, EarlyView.
A gas‐fed, zero‐gap, PEM CO2 electrolyzer is realized by incorporating PDDA+ ions onto the carbonaceous Co/N‐C electrocatalyst, with gaseous H2 and CO2 fed into the anode and cathode, respectively. Operating without an aqueous electrolyte, the system sustains a peak FECO of 65.1% at 100 mA cm−2. ABSTRACT Electrochemical carbon dioxide reduction (ECO2R)

The operational determination of wind stress on the Arctic ice pack

open access: yes, 1977
Abstract : The performance of routine FNWC sea level pressure analyses and forecasts in the Beaufort Sea is evaluated for driving an ice model. The geostrophic winds determined from the FNWC pressure fields are compared to geostrophic winds determined from the AIDJEX experiment observations.

An Integrated Oxygen‐Supplying Device and Predictive Multiphysics Model for Extended Ambient Transport of Insulin‐Producing Cells

open access: yesAdvanced Functional Materials, EarlyView.
Cell therapies typically rely on cold‐chain logistics and cryopreservation, limiting access and compromising cell quality. Here, a dual‐chamber device separates an oxygen‐supplying chamber from a hyaluronic acid cargo chamber, sustaining oxygen delivery for over 70 h and enabling ambient‐temperature shipment.
