Article Snippet: • Multi-technique (UV, DLS, AF4) analysis optimized Au-BSA-CUR drug carrier synthesis and loading efficiency.. • AF4-DAD used A401/A530 ratio to monitor real-time drug release with fullload value of 0.77 ± 0.01.. • AF4 enabled first-time monitoring of drug aggregation at low temperatures

Article Title: Mobilization of water-dispersible colloidal chromium and nickel in basalt-derived paddy soils: Role of Fe (hydr)oxides and organic matter.
Article Snippet: Basalt weathering can lead to heavy metal enrichment in soils, and nickel (Ni) isotopes can served as an effective tracer for this weathering process.. Water-dispersible colloids (WDCs) are ubiquitous in soil environments and can facilitate the long-range transport of sorbed pollutants.. Here, we analyzed soil colloidal distribution, concentration, morphology and Ni isotopes in soil to understand the potential mobilization of WDC-bound Cr and Ni in basalt-derived paddy soils.
