Field‐Programmed Anisotropy in Magneto‐Piezoelectric Composites for Material‐Encoded Mechanoperception

Advanced Materials, EarlyView.
Field‐programmed anisotropy imparts material‐level intelligence to soft composites. Magnetic torque dynamics drive magneto‐piezoelectric nanowires from random dispersion into deterministic axial alignment. The resulting hierarchical percolation networks confine electromechanical coupling to specific axes and intrinsically decouple superposed force ...

Design and results of the ice sheet model initialisation initMIP-Greenland: an ISMIP6 intercomparison [PDF]

The Cryosphere, 2018
Earlier large-scale Greenland ice sheet sea-level projections (e.g. those run during the ice2sea and SeaRISE initiatives) have shown that ice sheet initial conditions have a large effect on the projections and give rise to important uncertainties. The

A technique for generating consistent ice sheet initial conditions for coupled ice sheet/climate models [PDF]

Geoscientific Model Development, 2013
Abstract. A transient technique for generating ice sheet preindustrial initial conditions for long-term coupled ice sheet/climate model simulations is developed and demonstrated over the Greenland ice sheet using the Community Earth System Model (CESM).

Organic–Inorganic Hybrid Hole‐Selective Layer Interface Engineering for Enhanced Photoelectrochemical Water Oxidation on Bismuth Vanadate Photoanodes

Advanced Materials, EarlyView.
In this research the [4‐(3,6‐dimethyl‐9H‐carbazol‐9‐yl)butyl] phosphonic acid (Me‐4PACz) self‐assembled monolayers (SAMs) to bond with NiOx is first designed to be the organic‐inorganic hybrid hole‐selective layers, which promotes the BiVO4 photoanodes photoelectrochemical water splitting performance with 6.9 mA cm−2 photocurrent at 1.23 VRHE and at ...

A facet-based numerical model to retrieve ice sheet topography from Sentinel-3 altimetry [PDF]

The Cryosphere
In this study, we present a facet-based numerical model dedicated to ice sheet radar altimetry. The model simulates Sentinel-3 UnFocused-Synthetic Aperture Radar (UF-SAR) waveforms by calculating the backscattered radar signal over the 10 m facets of the

Exposure age and ice-sheet model constraints on Pliocene East Antarctic ice sheet dynamics [PDF]

Nature Communications, 2015
AbstractThe Late Pliocene epoch is a potential analogue for future climate in a warming world. Here we reconstruct Plio-Pleistocene East Antarctic Ice Sheet (EAIS) variability using cosmogenic nuclide exposure ages and model simulations to better understand ice sheet behaviour under such warm conditions.

Sustainable and Multifunctional Natural Macromolecular Polymers for Aqueous Zn Metal Batteries

Advanced Materials, EarlyView.
We comprehensively review the structure‐function relationships and regulatory mechanism of natural macromolecular polymers in stabilizing zinc anodes at the microscopic and mesoscopic scales. The interactions among polymer structures, optimization strategies, and regulatory mechanisms are discussed systematically summarizing recent related research ...

The potential of marine ice cliff instability for Amundsen Sea glaciers revisited

Annals of Glaciology
Marine ice cliff instability (MICI) is the hypothesis that self-sustained retreat of ice sheets can be initiated when sufficiently tall ice cliffs are exposed.

Impact of ocean forcing on the Aurora Basin in the 21st and 22nd centuries

Annals of Glaciology, 2016
The grounded ice in the Totten and Dalton glaciers is an essential component of the buttressing for the marine-based Aurora basin, and hence their stability is important to the future rate of mass loss from East Antarctica. Totten and Vanderford glaciers

A Three-Dimensional Model of the Antarctic Ice Sheet [PDF]

Annals of Glaciology, 1988
A preliminary version of a three-dimensional ice-sheet model for later use in climate models, but excluding ice shelves and basal sliding, is presented and applied to the Antarctic ice sheet. In the model, the three-dimensional fields of velocity and temperature are calculated in the coupled mode, and the temperature equation is integrated for 150 000 ...
