Development of a New Tool for Writing Research Key Information in Plain Language.

Background: The complexity of research informed consent forms makes it hard for potential study participants to make informed consent decisions. In response, new rules for human research protection require informed consent forms to begin with a key information section that potential study participants can read and understand. This research study builds on exiting guidance on how to write research key information using plain language.

Detection of low levels of trichloroethylene vapor with Raman spectrometry.

The response of a novel fiber-optic Raman probe to low levels of trichloroethylene (TCE) vapors is characterized. The detection limit of the current probe for TCE vapor is 34 mg/L, and the probe exhibits a fully reversible response. The probe uses an organic-polymer, low-density polyethylene to concentrate TCE vapors in the optical path of the fiber-optic Raman spectrometer.
