Physical modeling of glacier contact with bedrock (experiment)
Лëд и снег, 2015 Studies of the adhesive strength of glacial ice connection with bedrock has been studied using the analysis of the amplitude-frequency characteristics of acoustic emission (AE) in the frequency range from 15 Hz to 20,000 Hz.

Birth of a Large Iceberg in Pine Island Bay, Antarctica [PDF]
, 2004 This lithograph shows the break-off of a large iceberg from the Pine Island Glacier in West Antarctica. This event occurred between November 4th and 12th, 2001, and provides powerful evidence of rapid changes underway in this area of Antarctica.

Defect‐Rich 2D Layered Double Hydroxides Enhance Sonodynamic Antibacterial Therapy
Advanced Science, EarlyView.This study develops defect‐rich ultrathin ZnCuW‐LDH nanosheets (DR‐ZnCuW‐LDH) via acid etching. DR‐ZnCuW‐LDH exhibits fourfold enhanced US‐triggered ROS production due to oxygen defects and electronic modulation, demonstrating potent antibacterial efficacy in vitro/vivo.

American Journal of Botany, EarlyView.Abstract Premise Species of Deuterocohnia (17 spp.) show extraordinary variation in elevation (0–3900 m a.s.l.) and growth forms, and many have narrow geographic distributions in the west‐central Andes and the Peru‐Chile coast. Previous research using few plastid and nuclear loci failed to produce well‐resolved or supported phylogenies.

Spatial Distribution and Characteristics of Debris-Covered Glaciers in Xinjiang Based on CGI-XJ2020
Remote SensingDebris cover is widespread on glaciers and strongly alters their surface albedo, energy balance, and ablation. Using the Chinese Glacier Inventory of Xinjiang 2020 (CGI-XJ2020), this study investigates the spatial distribution of debris-covered glaciers ...

Advanced NanoBiomed Research, EarlyView.Encapsulated acriflavine (ACF) and copper oxide nanoparticles (CuO NPs) are coreleased from coaxial nanofibers, producing synergistic antiglioblastoma multiforme effects. ACF suppresses the hypoxia‐inducible factor 1α pathway related to many downstream factors for tumor growth, while CuO NPs generate reactive oxygen species that assist cuproptosis ...

Allanite U–Pb step-leaching ages of metapelites in the Imjingang belt, central Korea
Journal of Analytical Science and TechnologyBackground Allanite is a LREE-rich epidote-group mineral, and a potential chronometer for the greenschist-facies metamorphism. However, owing to the metamict nature of allanite, it is extremely difficult to secure sufficient amounts of mineral separates ...
