The applications of ultrathin, conductive films such as those made of graphene have many applications, but it's been thought their efficacy is limited to absorbing only half of the incidental light at ...

The latest research in ACS Applied Energy Materials has shown that vertically aligned silicon nanowire (VA-SiNW) arrays are capable of massively increasing light absorption and causing a significant ...

Infrared spectroscopy (IRS) is a technique used to analyze individual substances in isolation or a mixture, using their spectral information. IRS is based on the measurement of the wavelength and ...

The chameleon changes its color by adjusting the spacing between photonic crystals in its skin to modulate light reflection (Figure 1). A research team at the University of California at Berkeley has ...

Many asymmetric absorbers are currently based on a single-port system, where sound enters one side and is absorbed before a rigid wall. In this design, however, light and air are unable to pass ...
