Electrical engineers have determined the theoretical fundamental limit for how much electromagnetic energy a transparent material with a given thickness can absorb. The finding will help engineers ...

Hierarchical magnetic graphene–SiCN aerogels were constructed via a stepwise confinement strategy, in which ZIF-derived magnetic nanoparticles and a polysilazane-derived SiCN ceramic layer were ...

Researchers have discovered that proteins, specifically bovine serum albumin (BSA), can improve the microwave absorption capabilities of metal-organic frameworks (MOFs). The optimized composite, 2-BSA ...

Skoltech researchers have developed an ultrathin carbon nanotube coating that absorbs terahertz radiation on silicon waveguides, offering a practical fix for one of the biggest obstacles facing future ...

Harvard researchers built a racetrack-shaped quantum cascade laser that makes bright, stable, mid-infrared frequency combs on ...

In order to control noise, designers must first determine where the noise source or sources are how much each is contributing to the overall level, and their frequency signatures. In order to control ...

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 ...
