Filling a Gap in Materials Mechanics: Nanoindentation at High Constant Strain Rates up to 105 s−1

open access: yesSmall, EarlyView.
A piezoelectric nanoindentation platform enables constant strain‐rate testing up to 105 s−1, extending experimental capabilities to extreme deformation regimes. Distinct hardness upturns are revealed across crystalline and amorphous materials, verified as intrinsic responses through quasi‐static reloading.

Activatable smart contrast agents for photoacoustic imaging

open access: yesSmart Molecules, EarlyView.
This review highlights recent advances in smart activatable photoacoustic imaging (PAI) contrast agents, which dynamically modulate their optical properties in response to external stimuli or microenvironmental cues. It discusses their molecular design, activation mechanisms, biomedical applications, and future prospects for clinically tailored use ...

Towards improving the PF1B beamline McStas model through simulations of a beam characterization experiment

open access: yesJournal of Applied Crystallography, EarlyView.
McStas simulations of a recent time‐of‐flight characterization of the PF1B instrument at the Institut Laue–Langevin show good agreement with the current beamline model, while also highlighting opportunities to refine some parameters of the simulation using the collected time‐of‐flight data as a benchmark.The PF1B instrument at the Institut Laue ...

The Unintended Consequences of German Deterrence

open access: yesGlobal Policy, EarlyView.
ABSTRACT Germany's evolving deterrence posture boils down to continued participation in NATO nuclear sharing and an ambitious conventional rearmament program. Due to its non‐nuclear status and a result of decades of underinvestment, Germany prioritizes modern conventional weapons.
