Uncovering hidden bias in neutron diffraction residual strain measurements
Journal of Applied Crystallography, EarlyView.This work demonstrates that diffraction‐based residual strain calculations and uncertainty estimates depend on how grain populations are sub‐sampled, with important implications for interpreting residual stresses in heterogeneous materials with fine‐scale microstructure and strain gradients.When calculating residual strain via neutron or X‐ray ...

The Material Basis of 18th‐Century Meissen Porcelain
Archaeometry, EarlyView.ABSTRACT In the summer of 1708, the quest for making hard‐paste porcelain from Saxonian clay and other mineral resources succeeded. This was achieved by applying as its essential ingredient newly discovered pure kaolin from Heidelsberg near Aue, western Saxon Ore Mountains.

Magnetic properties of geraisites, the first tektite strewn field identified in Brazil
Meteoritics &Planetary Science, EarlyView.Abstract Geraisites are a newly recognized class of tektite from Brazil. They occur as centimeter‐sized, elongated to subspherical bodies scattered across surface gravel and shallow subsurface layers within a ~90‐km‐long strewn field extending between the municipalities of São João do Paraíso and Curral de Dentro, near the border between the states of ...

Effect of Intermediate Principal Stress on the Strength, Deformation, and Permeability of Sandstone
Energies, 2018 Although the mechanical behaviors and flow aspects of sandstone have been previously investigated, studies of the effect of the intermediate principal stress (σ2) on the strength, deformation, and permeability of sandstone are lacking. In this work,
