Microstructure-based simulations of the viscous densification of snow and firn [PDF]
The CryosphereAccurate models for the viscous densification of snow (understood here as a density below 550 kg m−3) and firn (a density above 550 kg m−3) under mechanical stress are of primary importance for various applications, including avalanche prediction and the

Nanorheology of Interfacial Water during Ice Gliding
Physical Review X, 2019 The slipperiness of ice is an everyday-life phenomenon, which, surprisingly, remains controversial despite a long scientific history. The very small friction measured on ice is classically attributed to the presence of a thin self-lubricating film of ...

Rheology of Ice II and Ice III from High‐Pressure Extrusion [PDF]
Geophysical Research Letters, 1986 Rheological parameters for ice II and ice III, needed in tectonic models of the icy satellites of the major planets, are obtained from extrusion experiments and compared with the rheology of ice I at pressures ∼2 kbar and temperatures ∼240K. Ice II has a higher effective viscosity (by a factor ∼10) than ice I at similar stress levels, whereas ice III ...

Validation of oil spill transport and fate modeling in Arctic ice
Arctic Science, 2018 Reliability of oil spill modeling in Arctic waters for response planning and risk assessments depends on the accuracy of winds, currents, and ice data (cover and drift) used as input.

Magnetic anisotropy and debris-dependent rheological heterogeneity within stratified basal ice
Journal of Glaciology, 2019 Basal ice of glaciers and ice sheets frequently contains a well-developed stratification of distinct, semi-continuous, alternating layers of debris-poor and debris-rich ice.

Rheology of ice cream: From fundamentals to applications
Innovations in Agriculture, 2023 Frozen desserts, including ice cream and related products, have captivated consumer palates for centuries due to their unique combination of taste, texture, and temperature. The complex interplay between ingredients, processing techniques, and the inherent rheological behaviour of these confections has drawn the attention of scientists, engineers, and ...

Bio‐Inspired Molecular Events in Poly(Ionic Liquids)
Advanced Functional Materials, EarlyView.Originating from dipolar and polar inter‐ and intra‐chain interactions of the building blocks, the topologies and morphologies of poly(ionic liquids) (PIL) govern their nano‐ and micro‐processibility. Modulating the interactions of cation‐anion pairs with aliphatic dipolar components enables the tunability of properties, facilitated by “bottom‐up ...

Strengthening ice through cyclic loading
Journal of Glaciology, 2017 New experiments reveal that the flexural strength of fresh water, columnar-grained ice loaded normal to the columns may be increased by about a factor of two upon reversed cyclic loading at a frequency of ~0.1 Hz at stress amplitudes of 1.3–2.6 MPa.
