Wear‐Activated Surface Engineering of Thermoplastic Polyurethane/Graphene Nanoplatelet Nanocomposites for Ice Friction Control

Polymer Composites, EarlyView.
Wear‐activated surface engineering of TPU/GNP nanocomposites through improved filler dispersion and interfacial anchoring of functionalized graphene nanoplatelets, leading to finer post‐abrasion textures and enhanced ice traction. ABSTRACT Graphene‐reinforced thermoplastic polyurethane (TPU) composites offer a promising route for developing ...

Modeled Subsidence of Permafrost Terrain 2025–2050: North‐Central Alaska

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT A large fraction of the Alaska terrain is underlain by regolith that contains excess ice (ice that in volume exceeds the natural pore space). Possible loss of excess ice would lead to ground subsidence, which in turn would disturb and destabilize the ground surface.

Disposition Model for Permafrost Degradation in Mountainous Regions

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Permafrost is a widespread thermal phenomenon in Arctic and high mountain regions that, in combination with steep terrain, exerts a key control on slope stability. Its degradation in response to climatic warming can modify the likelihood and timing of rockfall, debris flow and related mass movements. Robust information on the current state and

Evaluating Testability of Permafrost Models Through Physical and Thermal Testing in Complex Mountain Terrain, Yukon, Canada

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Due to its subsurface nature, permafrost cannot be directly observed with the naked eye or optical remote sensing. Consequently, accurately describing its distribution and thermal state is challenging. This is especially true in vast, remote environments, where obtaining comprehensive field data is demanding or improbable.

Repeated Pleistocene Permafrost Episodes in the Western Pannonian Basin

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Concerning the study of past periglacial processes, the Pannonian Basin is a key area as it contains the southernmost frost polygons found in Central Europe. The presence or absence of permafrost is still, however, a matter of debate, and data on the timing of frost action are also scarce.
