Mantle Structure and Flow Across the Continent‐Ocean Transition of the Eastern North American Margin: Anisotropic S‐Wave Tomography

Geochemistry, Geophysics, Geosystems, 2021
Little has been seismically imaged through the lithosphere and mantle at rifted margins across the continent‐ocean transition. A 2014–2015 community seismic experiment deployed broadband seismic instruments across the shoreline of the eastern North ...

Multimodal Structural Color Graphics Based on Colloidal Photonic Microdome Arrays

Advanced Functional Materials, EarlyView.
A hybrid photonic system combining colloidal crystals and microscale domes is designed to achieve four switchable optical states via the interplay of Bragg reflection and TIR interference. The graphics composed of the photonic microdome arrays provide tunable, angle‐sensitive structural coloration and concealed‐to‐revealed transitions, offering a ...

Operando Temperature Sensing at the Actual Electrocatalytic Interface by Nanodiamond Quantum Sensors

Advanced Functional Materials, EarlyView.
By integrating a wide‐field microscope with a custom‐designed electrolyzer, nanoscale temperature changes can be recorded in situ during the electrolysis process without interfering with ongoing electrochemical reactions. This method establishes a correlation between the interface temperature and specific electrochemical reactions, making the measured ...

Bio‐Inspired Nanoarchitected LiFePO4 Cathodes

Advanced Functional Materials, EarlyView.
Lithium iron phosphate (LFP) is synthesized using a bio‐inspired method, using acidic macromolecules similar to those found in many calcareous mineralized organisms to modulate the morphology and crystal growth of LFP‐carbon composite particles. The observations from this process indicate a non‐classical crystallization process, which subsequently ...

Tomographic evidence for compositional heterogeneity deep in earth’s mantle [PDF]

, 2002
In the past decade, tomographic imaging has revealed that trajectories of mantle convection are more complex than expected from end-member models of unhindered whole mantle circulation or layered convection with an interface at 660 km depth.

Membrane Wrapping for High Capacity and Rapidly Switchable Adhesives

Advanced Functional Materials, EarlyView.
A membrane‐wrapping mechanism enables high‐capacity, rapidly switchable adhesion by coupling suction, friction, and adhesion. Broadband performance is achieved in dry and underwater conditions, allowing fast, reversible manipulation of objects of diverse sizes and shapes, from delicate eggs and berries to flat, complex, or heavy objects. These outcomes

How Phase Transitions Impact Changes in Mantle Convection Style Throughout Earth's History: From Stalled Plumes to Surface Dynamics

Geochemistry, Geophysics, Geosystems
Mineral phase transitions can either hinder or accelerate mantle flow. In the present day, the formation of the bridgmanite + ferropericlase assemblage from ringwoodite at 660 km depth has been found to cause weak and intermittent layering of mantle ...

The mass-radius relationship from solar-type stars to terrestrial planets: a review

, 2008
In this review, we summarize our present knowledge of the behaviour of the mass-radius relationship from solar-type stars down to terrestrial planets, across the regime of substellar objects, brown dwarfs and giant planets.

A new vision of giant planet interiors: Impact of double diffusive convection [PDF]

, 2012
While conventional interior models for Jupiter and Saturn are based on the simplistic assumption of a solid core surrounded by a homogeneous gaseous envelope, we have derived new models with an inhomogeneous distribution of heavy elements within these ...
