Innovative Method of Combing Multidecade Remote Sensing Data for Detecting Precollapse Elevation Changes of Glaciers in the Larsen B Region, Antarctica

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2022
The Antarctic Peninsula has undergone dramatic changes in recent decades, including ice-shelf melting, disintegration, and retreat of the grounding line. The Larsen B ice shelf is of particular concern due to the unprecedented ice-shelf collapse in 2002.

Benthic trophic interactions in an Antarctic shallow water ecosystem affected by recent glacier retreat [PDF]

, 2015
The western Antarctic Peninsula is experiencing strong environmental changes as a consequence of ongoing regional warming. Glaciers in the area are retreating rapidly and increased sediment-laden meltwater runoff threatens the benthic biodiversity at ...

Durable Proton Exchange Membrane Based on Polymers of Intrinsic Microporosity for Fuel Cells

Advanced Materials, EarlyView.
A novel composite proton exchange membrane (PEM) design that leverages carboxylic acid‐functionalized polymers of intrinsic microporosity (cPIM‐1) and polyvinylpyrrolidone (PVP). Harnessing Lewis acid‐base interactions enables the development of a synergistic microporous structure that confines phosphoric acid clusters, enhancing proton conductivity ...

Permanent Plasma Surface Functionalization of Internal Surface Areas

Advanced Materials Interfaces, EarlyView.
With applications in various fields including biomedical sciences, textiles, or filter industry, stable functionalization of porous membranes is indispensable. Plasma‐activated species with specific reactivities infiltrate porous substrates at different penetration depths due to their distinct energies and diffusivities.

Development of the First Tritiated Tetrazine: Facilitating Tritiation of Proteins

ChemBioChem, Volume 23, Issue 23, December 5, 2022., 2022
A tritiated tetrazine based on a phenyl/pyridyl core structure was successfully radiolabeled with NaBT4 by reducing an aldehyde moiety. The synthon was effectively employed to label an antibody in vitro with pretargeted autoradiography. Abstract Tetrazine (Tz)–trans‐cyclooctene (TCO) ligation is an ultra‐fast and highly selective reaction and it is ...

Seismic signals generated at a water-ice interface from smoothed particle hydrodynamic simulations [PDF]

arXiv, 2023
The field of ice sheet, ice shelf and glacier-related seismology, cryoseismology, has seen rapid development in recent years. As concern grows for the implications of change in the great ice sheets of Greenland and Antarctica, so instrument advances and international field programs have expanded the availability of passive seismic datasets that contain

Climate-driven Shifts in Quantity and Seasonality of River Discharge over the past 1000 Years from the Hydrographic Apex of North America [PDF]

, 2008
Runoff generated from high elevations is the primary source of freshwater for western North America, yet this critical resource is managed on the basis of short instrumental records that capture an insufficient range of climatic conditions. Here we probe
