Nanorheology of Interfacial Water during Ice Gliding

open access: yesPhysical 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 ...

Microstructure-based simulations of the viscous densification of snow and firn [PDF]

open access: yesThe Cryosphere
Accurate 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

Genetically Programmed Shape‐Morphing of Engineered Living Materials

open access: yesAdvanced Functional Materials, EarlyView.
Here, bacterial and mammalian engineered living materials (ELMs) are presented, in which living cells direct genetically programmed and enzymatically mediated shape‐morphing. The resulting deformation and shape‐recovery can be actuated in a genetically controlled manner by an ELM incorporating out‐of‐equilibrium counteracting biochemical reactions with

Validation of oil spill transport and fate modeling in Arctic ice

open access: yesArctic 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.

On the rheology of till [PDF]

open access: yes, 2003
The deformation of subglacial till is instrumental in causing certain glacier surges, the motion of rapid ice streams in ice sheets, and ice-sheet surges which are associated with Heinrich events, and consequent rapid climatic shifts, during the last ice

Rheology of ice at the bed of Engabreen, Norway [PDF]

open access: yesJournal of Glaciology, 2000
AbstractA three-dimensional finite-element model is used to analyze field data collected as dirty basal ice flowed past an instrumented obstacle at the bed of Engabreen, a temperate glacier in northern Norway The ice is modeled as an incompressible power-law fluid, with viscosity , where ΠD is the second invariant of the stretching tensor, and B and n ...

Bioinspired Hydrogels with Broadly Programmable Mechanics for Soft‐Tissue Interfaces

open access: yesAdvanced Functional Materials, EarlyView.
Sea cucumber‐inspired gelatin hydrogels are formed by directional freezing and mechanically programmed through subsequent ionic treatment. Multiscale characterization and modeling link ion‐regulated chain interactions to directional load transfer within the aligned hierarchical architecture.

Magnetic anisotropy and debris-dependent rheological heterogeneity within stratified basal ice

open access: yesJournal 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.

Modelling ice mélange based on the viscous-plastic sea-ice rheology

open access: yes, 2023
Abstract. Ice mélange, which is a mixture of sea ice, bergy bits and icebergs, can have a strong influence on the sea-ice–ocean interaction. So far, ice mélange is not represented in climate models as numerically efficient realizations are missing. This motivates the development of an ice-mélange model based on the viscous-plastic sea-ice rheology ...

Rheology of ice cream: From fundamentals to applications

open access: yesInnovations 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 ...
