In this paper we examine the conditions for surface topography evolution and crack growth/fracture during the cyclic actuation of polysilicon microelectromechanical systems (MEMS) structures. The surface topography evolution that occurs during cyclic fatigue is shown to be stress-assisted and may be predicted by linear perturbation analyses. The conditions(More)
The synthesis, spectral characterization, and antibacterial activity of some new substituted 8-bromo-6-alkyl-isoxazolo[4,3-e]indoles are presented. Their antibacterial activity (MIC) against methicillin-susceptible Staphylococcus aureus and methicillin-resistant Staphylococcus aureus (MRSA) were determined. The results revealed that compounds 3e-3h(More)
