Background And Objectives: Delivery of acute ischemic stroke (AIS) therapies is contingent on the duration from last known well (LKW) to emergency department arrival time (EDAT). One reason for treatment ineligibility is delay in presentation to the hospital. We evaluate patient and neighborhood characteristics associated with time from LKW to EDAT.

Article Synopsis
  • Zeolites and mesoporous silicas are important porous materials used in applications like catalysis and gas separation, with their formation influenced by surfactants called structure directing agents (SDAs).
  • The study explores how these SDAs affect the nucleation and selection of zeolite crystal forms through molecular dynamics simulations, particularly focusing on the phase behavior of mixtures involving SDAs and a network-former.
  • It was found that while some zeolites do not benefit from mesophases during nucleation, five others do, indicating that these metastable phases can lower nucleation barriers and guide which crystal structures form.
