When assessing the stability performance of structures, two figures of merits are required: ground motion transmissibility and mechanical compliance. The former quantifies amplification ofground transmitted vibrations, and the second the displacement induced by on-board disturbance sources. Both must remain sufficiently low to keep structural response within stability requirements. In...
Liquid metals as thermal interface materials (TIMs) offer ultrahigh contact thermal conductance while their inherent compliance eliminates clamping stress-induced deformation in optical components, such as InGa bath or InGa gap cooling. However, their corrosivity toward metals (e.g., Cu, Al) necessitates protective coatings such as high-phosphorus electroless nickel (Ni-P), though minor...
