MXene-polymer bonding lets a thin underwater absorber tune resonance and damping chemically, shifting acoustic control from ...

This work deals with wave absorption in reciprocal asymmetric scattering problem by addressing the acoustic problem of compact absorbers for perfect unidirectional absorption, flush mounted to the ...

The absorption of airborne sound is still a subject of active research, and even more since the emergence of acoustic metamaterials. Although being subwavelength, the screen barriers developed so far ...

This latest accomplishment joins the company’s previously secured ASTM certifications, enhancing the features and expanding the end-uses for its microalgae-based bio-cement and bio-concrete. BOULDER, ...

Experts at the University of Bristol have discovered that the scales on moth wings act as excellent sound absorbers even when placed on an artificial surface. Experts at the University of Bristol have ...

Scientists have developed a new material: an ultra-thin film that can absorb over 99% of electromagnetic waves. The Korea Institute of Materials Science (KIMS) states it to be the “world's first ultra ...

The risk of hearing loss does not come just from loud machinery or other obvious noise. It can also affect people in public environments like theaters and concert halls. Absorbing this excess sound to ...

Experts at the University of Bristol have discovered that the scales on moth wings act as excellent sound absorbers even when placed on an artificial surface. The researchers, who recently discovered ...
