Physiotherapy ultrasound machines are commonplace in medicine and sports injury treatment but limitations with current calibration equipment mean they may be producing inaccurate doses that could lead ...

A recent study in Scientific Reports presented a graphene-based metamaterial as a solar absorber. The structure consisted of three layers: aluminum (Al) as the resonator, titanium nitride (TiN) as the ...

Light absorption is a cornerstone for several applications such as solar cells, photodetectors, and optical sensors, to name a few. Yet, the trade-off between the thickness of the absorber and its ...

Shock absorbers have several advantages: 1. Longer machine life: Shock absorbers significantly reduce shock and vibration on machinery. This decreases machinery damage, downtime, and maintenance cost.
