Raman spectroscopy is an analytical technique that allows for the assessment of molecular structure and the identification of materials by examining the rotational and vibrational modes of molecules.

While the world sprints toward ever faster mobile speeds, another connectivity story is quietly unfolding at the opposite end ...

Mechanical antennas represent a disruptive approach to low-frequency communication by exploiting the mechanical oscillation of electric charges or magnetic dipoles to generate electromagnetic ...

Research conducted by a team of scientists from Kaunas universities, Lithuania, revealed that low-frequency ultrasound influences blood parameters. The findings suggest that ultrasound’s effect on ...

The principle of this work is demonstrated by using a laser to levitated nanoparticles and make them carry an electric charge to become an antenna that receives an external electric field containing a ...

We all know how to block the DC offset of an AC signal — that just requires putting a capacitor in series, right? But what if the AC signal doesn’t alternate very often? In that case, things get a ...

Most oscilloscopes are fitted with filters to help improve measurement by reducing overall noise in an acquisition to improve signal-to-noise ratio (SNR). Even the most basic oscilloscopes include an ...

A scheme of simple band-pass RC- and LR- filters on operational amplifiers containing only one capacitor or inductor and 3 resistors is proposed. A comparison is made of the amplitude-frequency ...
