Article Synopsis
  • Single crystals of organic compounds that respond to heat or light are well-studied, but those showing extreme mechanical response are less common in research.
  • A tetrafluoro(aryl)sulfanylated bicyclopentane developed in this study exhibited a low-temperature thermosalient effect, where crystals jumped and disintegrated at temperatures below ∼193 K.
  • Investigations using various techniques revealed that the mechanical response is not solely due to a chemical transformation or phase transition, but rather related to the release of built-up strain and possibly influenced by microstructural changes or impurities within the crystal.

Background: Older adults commonly experience chronic medical conditions and are at risk of cognitive impairment as a result of age, chronic comorbidity, and medications prescribed to manage multiple chronic conditions. Anticholinergic medications are common treatments for chronic conditions and have been repeatedly associated with poor cognitive outcomes, including delirium and dementia, in epidemiologic studies. However, no study has definitively evaluated the causal relationship between anticholinergics and cognition in a randomized controlled trial design.
