Tracing the rapid loss of Breifonn, Norway’s southernmost glacier

open access: yesAnnals of Glaciology
Global climate change is causing glaciers to shrink, and in some cases, to vanish completely. Glaciers in Norway are no exception. Glacier inventories, archived imagery and topographic maps across Norway help trace the decadal evolution of individual ...

Reconstruction of Past Glacier Changes with an Ice-Flow Glacier Model: Proof of Concept and Validation

open access: yesFrontiers in Earth Science, 2021
Estimations of global glacier mass changes over the course of the 20th century require automated initialization methods, allowing the reconstruction of past glacier states from limited information. In a previous study, we developed a method to initialize

Selenium‐Integrated Cyanine Dye With Enhanced Photophysical Properties for Optoacoustic‐Guided Cancer Imaging and Therapy

open access: yesAdvanced Functional Materials, EarlyView.
This study introduces selenium‐integrated cyanine dye (Se‐Cyn), with superior photostability, absorption, and photothermal efficiency, outperforming ICG in NIR window. Its nanoparticle form remains stable in water, accumulates in tumors, and enables strong optoacoustic imaging and effective phototherapy outcomes.

RHEOLOGY OF GLACIER ICE

open access: yesLe Journal de Physique Colloques, 1985
A new method for calculating the stress field in bounded ice shelves is used to compare strain rate and deviatoric stress on the Ross Ice Shelf, Antarctica. The analysis shows that strain rate (per second) increases as the third power of deviatoric stress (in newtons per square meter), with a constant of proportionality equal to 2.3 x 10

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.

Weathering Dynamics Under Contrasting Greenland Ice Sheet Catchments

open access: yesFrontiers in Earth Science, 2019
Chemical weathering dynamics in Greenland Ice Sheet (GrIS) catchments are largely unknown, due to a scarcity of field data. This paper presents the most comprehensive study to date of chemical weathering rates from four GrIS catchments of contrasting ...

Modeling and Compensation of the Penetration Bias in InSAR DEMs of Ice Sheets at Different Frequencies

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2020
Interferometric synthetic aperture radar (InSAR) is able to provide important information for the characterization of the surface topography of glaciers and ice sheets.

Directing Near‐Perfect (001) Orientation in Wafer‐Scale BiOI Thin Films via Halide‐Mediated van der Waals Stacking

open access: yesAdvanced Materials, EarlyView.
Our work introduces a new framework that fundamentally changes how orientation in bismuth oxyhalide systems is approached. Comprehensive experiments, backed by theoretical models, reveal the pivotal role of halide anions to modify the van der Waals stacking energies required to direct orientation. Our method enables the fabrication of near perfect (001)

Prehospital locoregional anesthesia: a case series

open access: yesScandinavian Journal of Trauma, Resuscitation and Emergency Medicine
Background Standard prehospital pain management relies on opioids, which involved avoidable risks. Few studies have evaluated pre-hospital locoregional anesthesia (LRA), especially fascia iliaca compartment blocks (FICB) and femoral nerve blocks (FB). We
