The design of the vocal smoke detector incorporated psychoacoustic research to more effectively waken children. It also provided an opportunity to examine and improve the usability of an often-overlooked but critical household product. Human factors research into existing smoke detectors identified ergonomic and interaction opportunities in installation and use, which were addressed by an effective design and development process. The result of this effort was not just an appealing and usable product but a next-generation smoke detector that enhances safety by design.

Aquaporin Channels

Designing next-generation fuel cell and filtration devices requires the development of nanoporous materials that allow rapid and reversible uptake and directed transport of water molecules. Here, we combine neutron spectroscopy and first-principles calculations to demonstrate rapid transport of molecular H2O through nanometer-sized voids ordered within the layers of crystalline carbon nitride with a polytriazine imide structure. The transport mechanism involves a sequence of molecular orientation reversals directed by hydrogen-bonding interactions as the neutral molecules traverse the interlayer gap and pass through the intralayer voids that show similarities with the transport of water through transmembrane aquaporin channels in biological systems. The results suggest that nanoporous layered carbon nitrides can be useful for developing high-performance membranes.
