Green Synthesis of Stable Sub‐Nano Silver Clusters with Potential against Cancer
Journal of Nanomaterials, Volume 2024, Issue 1, 2024.Sub‐nano‐sized Ag‐clusters represent an intermediate class between isolated atoms and nanoparticles, and they can possess new, unexpected properties differing from bulk and nano‐sized particles. A simple, fast, one‐step, cost‐effective protocol was revealed to prepare stable sub‐nano‐sized Ag‐clusters with green synthesis.

AFRICAN JOURNAL OF BIOTECHNOLOGY, 2012 The essential oil of flowers and leaves of Porophylum ruderale (Asteraceae) was investigated for its molluscicidal and larvicidal activities, and its toxicities to brine shrimps. The essential oil was analyzed by gas chromatography-mass spectrometry (GC/MS). GC/MS analysis showed a total volatile content of 99.98% in the P. ruderale oil (PREO).
