Bayesian optimization of laser-aided fracture toughness specimen preparation
Open CeramicsReliable lifetime prediction of ceramic components requires fracture toughness measurements supported by sharp, reproducible artificial defects. Conventional notching techniques often lack consistency, are time-consuming, and are particularly limited for

Graphene in cryo-EM specimen optimization
Current Opinion in Structural BiologySpecimen preparation is a critical but challenging step in high-resolution cryogenic electron microscopy (cryo-EM) structural analysis of macromolecules. In the past decade, graphene has gained much recognition as the supporting substrate to optimize cryo-EM specimen preparation.

Characterization of transverse anisotropy in Poisson's ratio using three-point radial deformation measurements [PDF]
E3S Web of Conferences, 2019 Poisson's ratio (v) of rock specimens can be experimentally determined from radial deformation measurements in an unconfined compression test. This is commonly achieved by mounting a compressometer with diametric or perimetric measurement capability ...

Design and manufacturing optimization of epoxy-based adhesive specimens for multiaxial tests
Materials & Design, 2021 Specimen design and manufacturing quality are decisive factors in the experimental determination of material properties, because they can only be reliably determined if all undesired influences have been minimized or are precisely known.
