This paper presents a hexagonal piezoelectric micromachined ultrasonic transducer (PMUT) array that can avoid spurious modes known to occur by mode coupling with adjacent elements. By designing an ...

Various layered materials, including hexagonal boron nitride (h-BN), graphite, and molybdenum disulfide (MoS2), have been successfully exfoliated to be cationic two-dimensional (2D) materials for the ...

Corrosion of metals has always been one of the most challenging industrial problems. Protection of copper foil from the corrosion of water, chloride ions, sulfate ions, hydroxide ions, and oxygen is ...

Thin-walled tubes are widely used in industries like railway and civil engineering for their lightweight and Safety. This study conducted numerical analyses to investigate how different types of ...
