With exposure to air, many liquid metals spontaneously generate an oxide layer on their surface. In oscillatory rheological tests, this skin is found to introduce a yield stress that typically dominates the elastic response but can be tuned by exposing the metal to hydrochloric acid solutions of different concentration. We systematically studied the normal impact of eutectic gallium-indium (eGa...

Microelectromechanical systems (MEMS) have constituted an active R&D area over the last two to three decades, with one of the earliest application topics being microswitches. Typical designs involve actuation of microscale flexural elements (e.g., beams and membranes) to make a short or an opening in the transmission (signal) line. However, the problem of reliability of these switches persisted...

T he properties of materials often change drastically when their size is decreased to the nanometre range. For example, as the surface-to-volume ratio of a material is increased, typically its melting temperature depresses and its chemical reactivity tends to increase. Also, as the size of a crystal shrinks down to submicrometre sizes, it becomes more difficult to deform it plastically (that is...

This study aimed to evaluate the concentration of heavy metals in liquid effluents and to quantify the mercury content in dental amalgam waste generated by dental clinics. Three neighbouring cities in Northeast Algeria were considered in this study (Constantine, Skikda, and Annaba). Heavy metals, such as Hg, Cu, Zn, Fe, Ni, Mn, Cr, Cd, and Pb, were analysed in wastewater and then compared with ...

The tuned liquid column damper (TLCD) having a uniform cross-sectional tube of U-shaped, occupied with liquid is used as a vibrational response mitigation device. The tuned liquid column ball damper (TLCBD) is a modified TLCD, where, an immovable orifice, positioned at the middle part of the horizontal portion, is replaced by a metal ball. Different studies on the unconstrained optimization per...

When in the presence of liquid metal environments, structural materials can potentially lose the ability to deform and plastically flow. In the case of a ductile material, the result of this reduction in flow ability is a transition from ductile to brittle behavior, resulting in a brittle-like failure. This phenomenon is known as liquid metal embrittlement (LME) and is a subset of the more comm...
