The Tolman–Ehrenfest criterion of thermal equilibrium in scalar–tensor gravity by Numa Karolinski, Valerio Faraoni

“…Abstract The Tolman–Ehrenfest criterion for the thermal equilibrium of a fluid at rest in a static general-relativistic geometry is generalized to scalar–tensor gravity. Surprisingly, the gravitational scalar field, which fixes the strength of the effective gravitational coupling, does not play a role in determining thermal equilibrium. …”

Multi-scale mechanical properties of Al–Mg–Zr–Sc alloys fabricated by direct metal laser sintering: Towards single-material composites by Dominic Zettel, Piotr Breitkopf, Ludovic Cauvin, Pascal Nicolay, Roland Willmann

“…Single-material composites were fabricated by integrating dense and porous structures within a single geometry. Tensile testing of these composites showed that geometry and the cross-sectional ratio of ductile material influence mechanical properties significantly (tensile strengths ranging from 89.8 MPa to 112.2 MPa), with stress-strain responses displaying atypical behavior due to the brittle, porous matrix and embedded ductile truss-lattice structures.…”
