Spatiotemporally Heterogeneous Impact of Proglacial Lake on Himalayan Glacier Dynamics Revealed by Multisource Remote Sensing

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Proglacial lakes modulate lake-terminating glacier dynamics and can substantially amplify ice loss via frontal calving. While critical for accurate glacier projections, proglacial lake-glacier interactions remain poorly understood across the Himalayas ...

Post‐Modification of Tripyrenylenes to Enantiopure π‐Extended D3‐Symmetric Propellers

Chemistry – A European Journal, EarlyView.
The post‐modification of tripyrenylenes to π‐extended enantiopure propellers with tris‐phenanthrophenazines is presented and the chiroptical properties as well as the solid‐state packings investigated in comparison to the corresponding racemic mixtures.

Using SAR satellite data time series for regional glacier mapping

, 2018
With dense SAR satellite data time series it is possible to map surface and subsurface glacier properties that vary in time. On Sentinel-1A and RADARSAT-2 backscatter time series images over mainland Norway and Svalbard, we outline how to map ...

Synthesis and characterization of amphiphilic nitroxide 1,1,3,3–tetraethylisoindoline–2–oxyl–5–sodium sulfonate (TEIOSNa)

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract The synthesis and characterization of an amphiphilic nitroxide to be used as a controlling agent in a nitroxide‐mediated living radical polymerization in aqueous dispersion media is presented. In the first stage of nitroxide synthesis (phthalimide protection), two reaction methods were employed: traditional and microwave.

The influence of the lithological and geotechnical properties of rocks on the morphology of glacial valleys

, 2013
The glacial valley cross-profile has traditionally had its development attrituted to the physical properties of the eroding glacier, with the input of the properties of the eroded rock mass to the development of the valley system considered in a purely ...

Synthesis and characterization of a highly hydrophilic nanocomposite for wettability alteration, water/oil interfacial tension reduction, and enhanced oil recovery

The Canadian Journal of Chemical Engineering, EarlyView.
Mechanism of wettability alteration, interfacial tension reduction, and oil recovery by novel nanocomposite. Abstract The development of stable nanofluids (NFs) for enhanced oil recovery (EOR) relies on optimizing interactions between reservoir rocks and fluids.

Perspectives on the production of a glacier inventory from multispectral satellite data in Arctic Canada: Cumberland Peninsula, Baffin Island

, 2005
The consequences of global warming on land ice masses are difficult to assess in detail, as two-dimensional glacier inventory data are still missing for many remote regions of the world.

Seasonal grounding line migration at Orville Coast, West Antarctica, based on a 4.5-year Sentinel-1 time series

Journal of Glaciology
This paper analyzes seasonal grounding line migration from a 4.5-year perspective and with a high (6 days) data-sampling rate. We used a series of high-resolution (60 m) Sentinel-1 double-difference interferograms obtained in the years 2017–21 to monitor

Remediation of Organic Pollutant for Wastewater Treatment by Employing Sustainable Graphene Oxide/NiO‐ZrO2/Zeolite Ternary Composite Material

CleanMat, EarlyView.
Graphene oxide/NiO‐ZrO2/zeolite ternary composite was synthesized hydrothermally. Efficient adsorption of Congo red onto GO/NiO‐ZrO2/zeolite composite was studied. ABSTRACT The present study employs a novel method for the synthesis of graphene oxide (GO) based ternary composite utilized for the adsorption of Congo red (CR), an anionic dye molecule. The
