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 ...

Controlling low-frequency broadband sound using compact structures remains a core challenge in acoustics. Achieving efficient, wideband sound absorption with lightweight, thin materials is vital for ...

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 ...

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 ...

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 ...

Flyer is an enterprise specializing in the development of customized EM absorption and EM shielding materials and components for diverse industrial environments. Under the philosophy of ...

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 ...
