Exploring levels and correlates of health literacy in Arabic and Vietnamese immigrant patients with cancer and their English-speaking counterparts in Australia: a cross-sectional study protocol.

Introduction: For immigrants diagnosed with cancer, the stress of a cancer diagnosis and treatment can be amplified by unfamiliarity with the health system, lack of culturally and linguistically appropriate information, and inability to communicate efficiently and accurately with the treating team. Lower levels of health literacy may be one factor underlying poorer outcomes among immigrant patients with cancer, but there have been few studies exploring this issue to date. This study aims to investigate the levels and correlates of health literacy in two immigrant populations affected by cancer and their English-speaking counterparts.

Marked alkyl- vs alkenyl-substitutent effects on squaraine dye solid-state structure, carrier mobility, and bulk-heterojunction solar cell efficiency.

We report two new squaraine dyes substituted at the pyrrolic rings with n-hexyl (squaraine 1) or n-hexenyl (squaraine 2) chains. Although internal molecular structure variations are minimal, the presence of the terminal double bond results in a much more compact solid-state structure, dramatically affecting charge transport in the thin films; the hole mobility of 2 is approximately 5x that of 1, and the BHJ OPV power conversion efficiency (PCE) of 2 is approximately 2x that of 1. PCEs surpassing 2% for ambient solution-processed devices are demonstrated, the largest so far achieved for squaraine-based organic solar cells.
