TEM images showing the ultrastructures of silica-NW before and following chemical and thermal treatment. a shows silica-NWs prior to treatment to compare to structures after incubation. Structures following incubation in b 2-propanol, c ethanol, d AcN, e HCl, pH 1.5, f heating up to 70 °C, and g autoclaving for 15 min, 2 atm, 1. All silica-NWs remained stable following incubation in harsh conditions
