microspore culture was applied to induce embryogenesis in roses (rosa hybrida) cv. hav1. important factors affecting viability of isolated microspores and formation of multi-cellular structures including isolation media (nln, ab, b) and induction media were studied. the most responsive developmental stage of microspores (late unicellular) was determined using dapi staining. the least infection ...

This paper presents a principle to develop multi-function dielectric elastomer actuators (DEAs) that can concurrently accomplish linear actuation and sound generation through single electrical input. A centimeter-scale cone-shaped DEA is fabricated using silicone-based electrodes. Measurements of the vibro-acoustic response reveal pumping deformation contributes negligible extent in generation,...
