Engineers discover new physics principle to break sound absorption barriers in ventilated spaces
In everyday life, designing spaces that both let air flow and absorb sound can be a tricky balancing act. Usually, materials ...
Figure 1: Absorption enhancement in nanotextured a-Si:H absorbers. UV–vis absorption measurements (Fig. 1c) for the three different samples show enhanced absorption for nanotextured interfaces (red, ...
Black carbon (BC) is functionally defined as the absorbing component of atmospheric total carbonaceous aerosols (TC) and is typically dominated by soot-like elemental carbon (EC). However, organic ...
