This research investigates the improvements of ozone (O) annealing on the optical and etching characteristics of TiO/AlO multilayer band-pass filters designed for potential optoelectronic applications. The band-pass filters were fabricated using atomic layer deposition (ALD), and their performance was systematically analyzed after the addition of O annealing at moderate temperatures (up to 300 °C). Results reveal that O annealing improves the optical transmittance of the multilayers by approximately 40% without significant spectral changes (∼6 nm).

Article Synopsis
  • The use of silver nanoparticles (AgNPs) is growing in nanomedicine and biomaterials for their antimicrobial properties, with green synthesis being an effective method of production.
  • L. acapulcensis, a tree known for its antimicrobial compounds, can reduce silver to AgNPs and enhance their antimicrobial activity.
  • The study demonstrates that biogenic AgNPs synthesized with L. acapulcensis show higher antimicrobial potency and lower cytotoxicity compared to chemically produced AgNPs.

Because of their shared backgrounds, community health workers' (CHWs) care of patients/program participants (PAPAs) is assumed to be acceptable, and often not evaluated empirically. Using PRISMA guidelines, we reviewed 9560 articles from 5 databases, selected 37 articles for full-text review, and developed a 5-dimensional depth analysis (focus, context, meaning, range, and voices) to characterize quality/quantity of PAPA feedback. Depth analyses clarified a spectrum of PAPA responses from extremely positive to ambivalence to outright distrust and frustration with perceived CHW limitations.
