Why a World State is Unavoidable in Planetary Defense: On Loopholes in the Vision of a Cosmopolitan Governance [PDF]
, 2019 The main claim of this chapter is that planetary defense against asteroids cannot be implemented under a decentralized model of democratic global governance, as espoused elsewhere in this book.

Development of virtual morphometric globes using Blender
, 2015 Virtual globes - programs implementing interactive three-dimensional (3D) models of planets - are increasingly used in geosciences. Global morphometric models can be useful for tectonic and planetary studies.

Advanced Materials Interfaces, EarlyView.Aqueous directional ice templating (DIT) is developed for making NMC811 cathodes containing vertically aligned pore arrays through electrode thickness. The effects of calendering are studied for the DIT electrodes to find optimal calendering and simultaneously achieve high gravimetric and volumetric energy densities and rate capability for lithium ion ...

, 2013 Extensive photometric stellar surveys show that many main sequence stars show emission at infrared and longer wavelengths that is in excess of the stellar photosphere; this emission is thought to arise from circumstellar dust. The presence of dust disks is confirmed by spatially resolved imaging at infrared to millimeter wavelengths (tracing the dust ...

3D Printing of Highly Electrically Conductive Zinc for Sustainable Electronics Applications
Advanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.A 3D printable zinc ink system with active zinc particles in a shellac matrix is demonstrated. The results show high conductivity, stable performance of printed structures under varying humidity conditions, and promising application in disposable water‐activated batteries. This technology combining digital material assembly, reliable operation, and non‐
