Investigation into vibration filtering for reducing friction loss of ultrasonic motors through a numerical approach

Ultrasonic motors (UMs) have emerged as a leading solution for actuators in biomedical equipment, aerospace applications, and other fields, owing to their distinct advantages, such as compact structures and self-locking ability. The operating principle of ...

Bottom-up designing nanostructured oxide libraries under a lab-on-chip paradigm towards a low-cost highly-selective E-nose

Vasily Artemov

Background: The multisensor concept has been developed as a powerful alternative to well-known gas-analytical instrumentation for applications where a fast but accurate and reliable assessment of the environment is required. The concept follows a biology-i ...

3D characterization of kinematic fields and poroelastic swelling near the tip of a propagating crack in a hydrogel

Damien Jean Arthur Thomas Delespaul, Danila Zubko, John Martin Kolinski, Chenzhuo Li

In fracture mechanics, polyacrylamide hydrogel has been widely used as a model material in experiments due to its optical transparency, the brittle nature of its failure, and low Rayleigh wave velocity. Indeed, linear elastic fracture mechanics has been us ...

Orbital-selective metal skin induced by alkali-metal-dosing Mott-insulating Ca2RuO4

Henrik Moodysson Rønnow, Gianmarco Gatti

Doped Mott insulators are the starting point for interesting physics such as high temperature superconductivity and quantum spin liquids. For multi-band Mott insulators, orbital selective ground states have been envisioned. However, orbital selective metal ...

Spontaneous formation of a self-healing carbon nanoskin at the liquid-liquid interface

Pedro Miguel Nunes Pereira de Almeida Reis, Holger Frauenrath, Nicolas Candau, Reuben Yeo Jueyuan, Paul Grandgeorge, Enzo Jean Raymond Bomal

Biological membranes exhibit the ability to self-repair and dynamically change their shape while remaining impermeable. Yet, these defining features are difficult to reconcile with mechanical robustness. Here, we report on the spontaneous formation of a ca ...

Guided-acoustic stimulated Brillouin scattering in silicon nitride photonic circuits

Yang Liu

Coherent optomechanical interaction known as stimulated Brillouin scattering (SBS) can enable ultrahigh resolution signal processing and narrow-linewidth lasers. SBS has recently been studied extensively in integrated waveguides; however, many implementati ...

Damage-Based Assessment of the Fatigue Crack Initiation Site in High-Strength Steel Welded Joints Treated by HFMI

Alain Nussbaumer

This study aimed to identify the fatigue crack initiation site of high-frequency mechanical impact (HFMI)-treated high-strength steel welded joints subjected to high peak stresses; the impact of HFMI treatment residual stress relaxation being of particular ...
