Critical Review of Brazil Disk Techniques for Tensile Strength Characterization With an Emphasis on High Explosive Materials

open access: yesPropellants, Explosives, Pyrotechnics, EarlyView.
ABSTRACT Mechanical properties are a critical performance metric for many high explosive (HE) materials and tensile strength properties are particularly important. Direct tensile measurements using dogbone shaped samples are the gold standard but they have the disadvantage that they are fairly large and require samples machined from billets.

Anticlastic Curvature and Material Freedom

open access: yesphysica status solidi (b), EarlyView.
Anticlastic curvature occurs in bent bars for positive Poisson's ratio; synclastic curvature occurs for negative Poisson's ratio provided the material is homogeneous and elastic. Some planar negative Poisson's ratio materials exhibit anticlastic saddle curvature rather than convex curvature in bending due to effects of 3D structure.

Roughness Measurements at Small and Uneven Surfaces of Ceramic Foam Filters

open access: yesSurface and Interface Analysis, EarlyView.
ABSTRACT This study investigated the possibility of roughness characterization of ceramic foam filters using a laser scanning microscope, examining the influence of magnification, measured area, cutoff wavelength (λc), measured roughness parameter, and position within the ceramic foam on the measured roughness data. Firstly, the effect of magnification

The Impact of Dust Particles on the Function of Screen‐Printed Triple‐Mesoscopic Perovskite Solar Cells

open access: yesSmall, EarlyView.
Screen‐printed mesoporous carbon perovskite solar cells offer an accessible route to scalable green energy. This study investigates the impact of dust particle contamination during the manufacture of this type of solar cell. Results suggest clean rooms may be unnecessary if strict cleanliness is maintained during storage and printing processes in ...

Influence of Heat Treatment Temperature on Crevice and Pitting Corrosion of UNS S32205 Duplex Stainless Steel

open access: yessteel research international, EarlyView.
Heat treatments that alter the proportions of austenite and ferrite phases or induce the precipitation of phases such as sigma in duplex stainless steel UNS S32205 make it more susceptible to pitting and crevice corrosion. However, the effects of these treatments are not always evident when analyzed using the cyclic polarization technique.

On the optimization of the geometric pattern for structured illumination based X‐ray phase contrast and dark‐field imaging: a simulation study and its experimental validation

open access: yesJournal of Synchrotron Radiation, EarlyView.
Single‐mask phase contrast and dark‐field imaging methods offer the great advantage of being simple to implement, translating most of the complexity to the numerical side. In this work, we study the impact of the modulation topology on the image quality retrieved both on numerical simulation and experiments.Phase contrast and dark‐field imaging are ...

Peixe Zircon as a Quality Control Reference Material in U‐Pb Geochronology by LA‐ICP‐MS

open access: yesGeostandards and Geoanalytical Research, EarlyView.
Key Points Peixe#0 zircon was characterised for U‐Pb geochronology using CA‐ID‐TIMS, SIMS and a long‐term LA‐ICP‐MS data set. The consistent results establish Peixe#0 as a reference material for U‐Pb quality control. Trace element heterogeneity requires careful, CL‐guided spot selection.
