• A participant asked how plasmid DNA escapes from nanoparticle carriers, highlighting a key mechanistic gap in non-viral gene-delivery research.

• nsh proposed building an ultrasonic transducer array for “sonocrystallization” experiments and shared an eBay listing for a 48-element parametric speaker kit, questioning whether its class-D amplifier has adequate frequency response.

• nmz787 suggested repurposing dental ultrasonic cleaning transducers—previously discussed in a vacuum/semiconductor chat—for precision wire-bonding of micro-scale wires to silicon chips.

• kanzure provided a curated bibliography of ultrasound-related papers at https://diyhpl.us/~bryan/papers2/ultrasound/ to support the sonocrystallization effort.

• nsh located a ResearchGate paper on “Applications of Ultrasound to Chiral Crystallization, Resolution and Deracemization” and posted its Sci-Hub mirror (xiouras2018.pdf) as a promising starting point for chiral-control experiments.
