# Key Points from IRC Discussion

• Optalysys optical computing technology was discussed, with questions about data processing capacity and state change frequency in programmable holographic memory systems.

• Piezoelectric applications were explored, including Murata's fluid control systems and piezoelectric pulsed molecular beam sources for creating high-intensity molecular beams.

• Helium microscopy and Neutral Atom Microscopy were discussed as imaging technologies that use gas reflection from sample surfaces rather than secondary electron emission.

• Multilayer ceramic capacitors (MLCCs) were suggested as an alternative to disk piezos for actuators, noting they are tiny, inexpensive (10,000 for $20), and exhibit piezoelectric properties.

• Several open-source plasmid editors were recommended, including UGENE, Gentle-M (GPL-licensed), and GENtle2 with an online version available at gentle.synbiota.com.

• PyPENELOPE and PENEPMA were highlighted as simulation tools for electron-photon transport in materials and x-ray spectra in complex geometries, respectively.

• A conceptual museum exhibit was proposed to demonstrate microscopy principles using bouncy balls or water droplets to illustrate particle reflection imaging at a macroscopic scale.
