Advanced Engineering Materials, EarlyView.This study explores a process chain to produce dispersoid‐strengthened CuCr1Zr for applications requiring high strength and conductivity. Using gas‐atomized powder and copper‐plated alumina nanoparticles, additive manufacturing is performed via powder bed based additive manufacturing with green and red lasers, followed by heat treatment.

Advanced Engineering Materials, Volume 27, Issue 7, April 2025.In this study, the effect of specific ball‐milling energy (SBME) on the mechanical and corrosion properties of graphene nanoplatelets (GNPs) Zn matrix composites is presented. GNPs are uniformly dispersed in the Zn powder mixtures at the optimal SBME of 32.82 kJ g−1.

The complex planetary synchronization structure of the solar system
, 2014 The complex planetary synchronization structure of the solar system, which since Pythagoras of Samos (ca. 570-495 BC) is known as the music of the spheres, is briefly reviewed from the Renaissance up to contemporary research.

Saving Planetary Systems: Dead Zones and Planetary Migration [PDF]
The Astrophysical Journal, 2007 The tidal interaction between a disk and a planet leads to the planet's migration. A long-standing question regarding this mechanism is how to stop the migration before planets plunge into their central stars. In this paper, we propose a new, simple mechanism to significantly slow down planet migration, and test the possibility by using a hybrid ...

Advanced Engineering Materials, EarlyView.A novel approach for alloy development in laser powder bed fusion is introduced. Instead of producing massive samples of one composition at a time, prepressed powder bed samples produced from powder mixtures are processed. Guidelines for the selection of precursor powders are developed.

Advanced Engineering Materials, Volume 27, Issue 6, March 2025.In the present work, synthesizing nanoscrystalline Fe65Co35 alloy by mechanical alloying is focused on, adding cyclohexane (C6H12) acting as a process control agent (PCA). PCAs are effective in favoring nanostructured alloys with uniform grain size. The production of this type of alloy is a promising approach to tune the magnetic hardness in Fe65Co35 ...
