Validation of a geometric compliance by the measurement of distances in the displacements space
International Journal of Metrology and Quality Engineering, 2017 The objective of the study is to show that a one-way machining simulation can be qualitatively satisfactory to validate a range of parts machined on a manufacturing with machine-tools 3 axis, even if they must meet geometric tolerances. A reflection on a

Fuzzy Analysis of Geometric Tolerances Using Interval Method
, 2006 The quality and performance of any mechanical system are greatly influenced by the GD&T (geometric dimensioning and tolerancing) used in its design. A proper consideration of the various types of tolerances associated with different components could not ...

Intracrystalline Void‐Mediated Toughening of Brittle Crystals in Quail Eggshells
Advanced Functional Materials, EarlyView.In quail eggshells, the high density and disordered arrangement of intracrystalline voids inhibit lattice cleavage, suppress long‐range crack propagation, and promote deformation twinning and quasi‐plasticity, serving as an essential toughening motif. We show that these voids remain within a narrow subcritical size range and therefore predominantly do ...

Advanced Functional Materials, EarlyView.An amphiphilic GOx nanoamphizyme was constructed by covalently introducing hydrophobic PPNI linkers onto GOx, enabling spontaneous self‐assembly into tunable nanoparticles. Mild crosslinking further stabilized the assemblies and enhanced catalytic performance and stability.
