Thermal Atomic Layer Etching of Cobalt and Other Transition Metal Films
A novel stepwise chemical etching method for precise and controlled removal of metal surfaces using protic compounds. Technology Summary This technology introduces a method for etching metal or element surfaces by initially contacting the surface with a protic compound to create a modified layer, followed by exposure to a protic ligand-forming compound...

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....
