The structural diversity of zincocenes: half-sandwich, silpped-sandwich and dimetallocene structures

Structural diversity of bimetallic rhodium and iridium half sandwich dithiolato complexes.

The synthesis of a range of rhodium(iii) and iridium(iii) half sandwich complexes with aryl dithiolato ligands of varying geometry and flexibility are reported. These include dinuclear [Cp*M(S-R-S)]2 complexes 3b and 4b, M = Rh, Ir; S-R-S = naphthalene-1,8-dithiolate (b) and four dinuclear complexes bearing bridging dithiolate ligands [(Cp*M)2(μ2-Cl)(μ2-S-R-S)]Cl 3c, 4c, 5b, 6b, M = Rh, Ir; S-R...

Acoustics of Sandwich Structures

USC’s work on sandwich structure acoustics began in 1998 and has evolved in close collaboration with the M.C. Gill Corporation, a leading manufacturer of sandwich panels for aircraft interiors. The work has had both an applied mission and an academic focus, and presents an example of university-industry collaboration can produce mutual benefit while advancing scientific understanding. Here, we ...

Fabrication and structural performance of periodic cellular metal sandwich structures

Metallic sandwich panels with periodic, open-cell cores are important new structures, enabled by novel fabrication and topology design tools. Fabrication protocols based on the sheet forming of trusses and shell elements (egg-boxes) as well as textile assembly have allowed the manufacture of robust structures by inexpensive routes. Topology optimization enables control of failure mechanisms at ...

Structural-Acoustic Optimization of Composite Sandwich Structures: A Review

We review recent advances in the area of composite sandwich modeling, sensitivity analyses, optimization techniques and applications, with the focus on structuralacoustic problems. The optimization of sandwich structures is with respect to passive design parameters, such as material constants, geometric parameters, cellular core geometry and boundary conditions.
