Experimental schematic of the hybrid system and ToF apparatus.
(A) A schematic of the experimental apparatus, including the LQT, the high voltage pulsing
scheme (shown as solid and dashed lines), and the ToF. (B) An illustrative experimental
time sequence that depicts initialization of a Ba+ crystal, production of BaOCH3 +
(visualized as dark ions in the crystal) through reactions with methanol vapor, and subsequent MOT immersion. (C) Sample mass spectra obtained after ejecting the LQT
species into the ToF after various MOT immersion times, ti, along with an inset depicting a superimposed fluorescence image of an ion crystal immersed in the Ca MOT. (D) Mass spectra of photofragmentation products collected after inducing photodissociation of
BaOCa+...

Plants like the Jewelweed (Impatiens capensis; or commonly, spotted touch-me-not) use stress ingeniously for the ballistic dispersal of their seeds. The plant stores energy in its seed pods in the form of inbuilt stresses by controlling tissue hydration. When gently touched, these pods explode and curl up to launch their seeds. Using a similar concept, S. Sundaram and coworkers demonstrate the use of 3D-printing to fabricate flat electronic composites with residual stress in specific regions.
