Thermokarst lake inception and development in syngenetic ice-wedge polygon terrain during a cooling climatic trend, Bylot Island (Nunavut), eastern Canadian Arctic [PDF]
The Cryosphere, 2020 Thermokarst lakes are widespread and diverse across permafrost regions, and they are considered significant contributors to global greenhouse gas emissions.

Biogeochemical Processes in the Active Layer and Permafrost of a High Arctic Fjord Valley
Frontiers in Earth Science, 2020 Warming of ground is causing microbial decomposition of previously frozen sedimentary organic carbon in Arctic permafrost. However, the heterogeneity of the permafrost landscape and its hydrological processes result in different biogeochemical processes ...

Monitoring of thermal contraction cracking at an ice wedge site, central Spitsbergen [PDF]
, 1999 P(論文)Thermal contraction cracking was monitored for two years in a continuous permafrost region. A dilatometer read the separation of a pair of benchmarks installed at both sides of an ice-wedge trough. The outputs were recorded in a data logger together

The importance of freeze/thaw cycles on lateral tracer transport in ice-wedge polygons [PDF]
, 2021 Abstract. A significant portion of the Arctic coastal plain is classified as polygonal tundra and plays a vital role in soil carbon cycling. Recent research suggests that lateral transport of dissolved carbon could exceed vertical carbon releases to the atmosphere.

Liquid‐Responsive Shape‐Memory Nanofiber‐Reinforced Scaffolds for Cartilage Repair
Advanced Science, EarlyView.A liquid‐responsive shape‐memory, nanofiber‐reinforced QCG scaffold combines conformal defect filling, an aligned architecture that is structurally permissive for endogenous cell infiltration, and sustained KGN release. This integrated design enhances BMSC viability, migratory activity, and chondrogenic differentiation and promotes hyaline cartilage ...
