Development and validation of the airway surgery enclosure for high-risk aerosol-generating airway procedures: a bench and clinical study.

Procedures on the upper airway in patients with respiratory viruses are considered to carry the greatest risk of infection spread to operating room personnel through aerosolization. Appropriate personal protective equipment must be worn, but availability varies worldwide and resources may be limited. We describe the development, validation, and safe implementation of a reusable enclosure with an inexpensive, acrylic design, for use in high-risk airway procedures.

Direct HO Synthesis, without H Gas.

We report here the direct hydrogenation of O gas to form hydrogen peroxide (HO) using a membrane reactor without H gas. Hydrogen is sourced from water, and the reactor is driven by electricity. Hydrogenation chemistry is achieved using a hydrogen-permeable Pd foil that separates an electrolysis chamber that generates reactive H atoms, from a hydrogenation chamber where H atoms react with O to form HO.
