This paper presents a beam structure of a new metamaterial-inspired dynamic vibration attenuation system. The proposed experimental research presents a designed cantilevered zigzag structure that can have natural frequencies orders of magnitude lower than a simple cantilever of the same scale. The proposed vibration attenuation system relies on the masses places on the zigzag structure thus changing the dynamic response of the system. The zigzag plates are integrated into the host structure namely a cantilever beam with openings, forming what is referred to here as a metastructure. Experimental frequency response function results are shown comparing the response of the structure to depending on the natural frequency of the zigzag structures. Results show that the distributed inserts in the system can split the peak response of the structure into two separate peaks rendering the peak frequency a low transmission frequency. These preliminary results provide a view of the potential of research work on active-controlled structures and nonlinear insert-structure interaction for vibration attenuation.

The title compound, [Zn(CH3CO2)Cl(C14H14N4)]n, is a one-dimensional coordination polymer in which the ZnIIion is tetrahedrally coordinated by two N atoms of a bridging 1,1′-[1,4-phenylenebis(methylene)]di-1H-imidazole ligand, an acetate O atom and a Cl atom. The Cl atom, two acetate O atoms and two acetate C atoms are located on a mirror plane. The coordination of the diimidazole ligand to the ZnIIion gives an infinite one-dimensional zigzag structure along theb-axis direction with the charge balanced by the chloride and acetate ions.

We have investigated Al adsorption on the W (100) surface using LEED and low energy Ion Scattering Spectroscopy (ISS). We observe a p(2 × 1) double domain LEED image for the 1.0 ML Al/W (100) surface at annealing temperature 850°C. We also measured the Al adsorption site at the Al/W (100) — p(2 × 1) surface using ISS. It is found that Al atoms adsorbed at 0.7±0.1 Å aside from the center of the bridge sites with a zigzag structure — one atom adsorbs at the right-hand side and next atom at the left-hand side along the [100] direction. The height of the adsorbed Al atoms is determined to be 1.75±0.15 Å above the W surface layer.
