Arctic sea ice thickness and volume declining [PDF]

Eos, Transactions American Geophysical Union, 2013
The record low extent of Arctic sea ice area in September 2012 made headlines. Studies using models have suggested that sea volume has also been declining. A new study by Laxon et al. confirms this with observational data. The authors used satellite radar observations from the European Space Agency CryoSat‐2 mission to estimate Arctic sea ice thickness

Magnetically Guided Mechanoactive Mineralization Scaffolds for Enhanced Bone Regeneration

Advanced Functional Materials, EarlyView.
A 3D‐printed ‘rebar‐concrete’ inspired scaffold (PGS‐P@MGel) synergizes spontaneous biomineralization with magneto‐mechanical stimulation through PDA@Fe3O4‐embedded hydrogel. This dual biointerface activates Piezo1/β‐catenin/YAP mechanotransduction axis, enhancing BMSCs osteogenesis and angiogenesis simultaneously.

Influence of stochastic sea ice parametrization on climate and the role of atmosphere–sea ice–ocean interaction [PDF]

, 2014
The influence of a stochastic sea ice strength parametrization on the mean climate is investigated in a coupled atmosphere–sea ice–ocean model. The results are compared with an uncoupled simulation with a prescribed atmosphere.

Comprehensive Si Anode Design for Sulfide‐Based all‐Solid‐State Batteries: Insights into Si‐Electrolyte Synergy for Mitigating Contact Loss

Advanced Functional Materials, EarlyView.
Silicon anodes in sulfide‐based all‐solid‐state batteries suffer from interfacial instability caused by volumetric fluctuations and contact degradation, restricting their practical implementation despite high capacity. This study presents design strategies that leverage controlled active material expansion and an elastic recoverable anolyte to form an ...
