Assessing Glacier Boundaries in the Ala-Archa Valley of Kyrgyzstan by Using Sentinel-1 SAR Dataset and High-Resolution UAV Imagery

open access: yesRemote Sensing, 2023
The significant retreat of glaciers in terms of climate change compels researchers to increase the frequency of studies regarding the transformations occurring in glacier boundaries. In this study, we provided glacier area delineation of Ala-Archa valley

Mapping Samudra Tapu glacier: A holistic approach utilizing radar and optical remote sensing data for glacier radar facies mapping and velocity estimation

open access: yesAdvances in Space Research, 2022
Himalayan glaciers have shown more sensitivity and visible changes to the climate change and global warming in the last 150 years. The highly rugged topography and inaccessible remote areas makes satellite images as the most appropriate source of information retrieval.

APTES‐Mediated Ti‐Squarate MOF/n‐GaN Nanowire Photoanodes for Efficient Photoelectrochemical Water Splitting

open access: yesAdvanced Functional Materials, EarlyView.
The APTES linker establishes a permanent interfacial dipole, reducing the work function of n‐GaN from 3.55 to 3.29 eV. This strengthens the built‐in electric field, significantly accelerating hole extraction to drive the oxygen evolution reaction (OER). Ultimately, this tailored charge‐separation architecture achieves a remarkable 4.78‐fold enhancement

Mamba-trident: terrain-guided tri-modal Mamba network for mapping little ice age glaciers

open access: yesInternational Journal of Applied Earth Observations and Geoinformation
The Little Ice Age (LIA) maximum glacier extent provides a pre-industrial baseline for quantifying centennial-scale glacier retreat. However, post-LIA surface modification weakens the spectral and textural contrasts between glacial deposits and ...

Assessing glacier retreat and landform production at the ‘debris-charged’ snout of Kvíárjökull, Iceland [PDF]

open access: yes, 2010
Iceland is a critical location for the study of glacier fluctuations and landform production in response to climate change due to its diverse glacial legacy and its archive of aerial photographs that provide accurately dated records of glacier retreat ...

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.
