Vibro-acoustic metamaterial with mass and flexible stem array

WSU researchers have developed a novel device combining the effects of negative effective elastic modulus and negative effective mass, acting as local resonators that can damp out vibrations and sound at multiple frequencies. This class of metamaterials has the superior ability to attenuate sound and have a much greater ability to block dynamic disturbances....

Compositions, Process, and Method for Producing Hybrid Green Cements and Their Concrete Products

A Wayne State University researcher has developed a novel method to make sustainable Hybrid Green Cements (HGC) from low cost minerals and waste minerals such as coal, ash, bio-mass ash, or mine tailings. Key issues that the researcher has identified include optimal ranges of hybrid mix compositions, processing, and curing conditions. HGC provides...
