Nanoindentation of Bridgman YBCO samples [PDF]

, 2012
In this study, the mechanical properties of YBa2Cu3O7−x, obtained by the Bridgman technique, were examined using a Berkovich tip indenter on the basal plane (0 0 1). Intrinsic hardness was measured by nanoindentation tests and corrected using the Nix and

Testing 3D Printed Carbon Fiber Durability for Next‐Gen Fusion Reactors via Proton Irradiation

Polymer Composites, Volume 47, Issue 1, Page 924-941, 10 January 2026.
Schematic of proton irradiation effects on carbon fiber samples evaluated via nanoindentation and Raman spectroscopy. ABSTRACT Carbon fiber‐reinforced composites are promising candidates for plasma‐facing components (PFCs) in next‐generation fusion reactors due to their high strength‐to‐weight ratio, thermal stability, and radiation resistance. However,

Water Parameters and Hydrodynamics in Rivers and Caves Hosting Astyanax mexicanus Populations Reveal Macro‐, Meso‐ and Microhabitat Characteristics

Ecology and Evolution, Volume 16, Issue 1, January 2026.
From 2009 to 2025, we have recorded the physicochemical parameters of the water and the hydrological regimes at localities hosting Astyanax mexicanus cavefish and surface fish populations in Mexico. Sampling 13 caves and 30 surface stations revealed strong signatures of the two macrohabitats, but also significant differences in specific water ...
