Phase‐Pure and Size‐Tunable Tin Halide Perovskite Quantum Dots

open access: yesAdvanced Materials, EarlyView.
A trioctylphosphine oxide modulated protocol allows for the synthesis and study of the optical properties of a broad library of tin halide perovskite quantum dots across multiple A‐ and X‐site compositions with precise size tuning while eliminating unwanted 2D phases.

Foreword to the thematic cluster: the Arctic in Rapid Transition—marine ecosystems [PDF]

open access: yesPolar Research, 2015
The Arctic is warming and losing sea ice. Happening at a much faster rate than previously expected, these changes are causing multiple ecosystem feedbacks in the Arctic Ocean.

Arctic Ocean circulation and variability – advection and external forcing encounter constraints and local processes [PDF]

open access: yesOcean Science, 2012
The first hydrographic data from the Arctic Ocean, the section from the Laptev Sea to the passage between Greenland and Svalbard obtained by Nansen on his drift with Fram 1893–1896, aptly illustrate the main features of Arctic Ocean oceanography and ...

Nutrient cycling in the Arctic and Subarctic oceans: a stable isotope study [PDF]

open access: yes, 2023
Anthropogenic global warming is actively changing nutrient supply and the food web of the Arctic Ocean and the subpolar regions. This study uses the stable isotopes of dissolved silicon and nitrate, two vital nutrients for marine life, to investigate ...

Two Routes to Land: Genomic Underpinnings of Parallel Aerial Egg Deposition in Aquatic Old‐World Pila and New‐World Pomacea (Ampullariidae)

open access: yesAdvanced Science, EarlyView.
Comparative genomics of Gondwana‐diverged Pila and Pomacea reveals parallel evolution of aerial oviposition. Convergent chromosomal rearrangements reshape regulatory landscapes within topologically associating domains. Lineage‐specific gene family expansions and viral‐derived perivitelline proteins (PV1) underpin desiccation resistance.

The Arctic Ocean marine carbon cycle: evaluation of air-sea CO2 exchanges, ocean acidification impacts and potential feedbacks [PDF]

open access: yesBiogeosciences, 2009
At present, although seasonal sea-ice cover mitigates atmosphere-ocean gas exchange, the Arctic Ocean takes up carbon dioxide (CO2) on the order of −66 to −199 Tg C year−1 (1012 g C), contributing 5–14% to the global balance of CO2 ...

Moisture transport from the Arctic: a characterization from a Lagrangian perspective

open access: yesCuadernos de Investigación Geográfica, 2018
The Arctic Ocean has suffered extreme reductions in sea ice in recent decades, and these observed changes suggest implications in terms of moisture transport.
