Formation of silicic crust on early Earth and young planetary bodies in an Iceland-like setting

Communications Earth & Environment
Four billion years ago, Earth’s surface was covered with a thick basaltic crust and, similar to other rocky planets and the Moon, parts of this basaltic crust underwent partial melting to produce silicic crust.

Long-lived Paleoproterozoic eclogitic lower crust

Nature Communications, 2021
The nature of the lower crust and the crust-mantle transition is fundamental to Earth Sciences. Here, the authors provide evidence for long-lasting presence of lower crustal eclogite below the seismic Moho, challenging conventional models.

Theoretical Spectra of Terrestrial Exoplanet Surfaces [PDF]

, 2012
We investigate spectra of airless rocky exoplanets with a theoretical framework that self-consistently treats reflection and thermal emission. We find that a silicate surface on an exoplanet is spectroscopically detectable via prominent Si-O features in ...

Reactive Laser Additive Manufacturing of Hierarchically Structured Aerogels

Advanced Materials, EarlyView.
Reactive laser additive manufacturing transforms printing into a chemically active synthesis step. Salt‐enabled transient reaction environments drive in situ formation of hierarchically structured graphitic aerogels with microtubular and nanoscale features in seconds.

3D Printing of Stretchable, Compressible and Conductive Porous Polyurethane for Soft Robotics

Advanced Materials Technologies, EarlyView.
A 3D‐printable porous dopamine‐polyurethane acrylate elastomer results in conductive, stretchable, and compressible structures that can be metallized in situ through catechol‐mediated silver reduction. The resulting material function as both compliant soft robot with a and strain sensors without complex assemblies, enabling fully 3D‐printed soft ...

Electromagnetic-deformational waves of the Earth crust

Геофизический журнал, 2016
This article briefly analyzes mechanisms of mechanoelectromagnetic transformations of the earth’s crust. It demostrates that the presence of these effects leads to the appearance of electromagnetic satellites, which are secondary electromagnetic waves ...
