Vapor-based synthesis of ultrathin hydrogel coatings for thermo-responsive nanovalves: Thermo-responsive nanovalves were fabricated by depositing ultrathin hydrogel coatings inside nanoporous track-etched polycarbonate membranes. The hydrogel coatings swell in response to changes in temperature, controlling the flow through a channel and creating a nanovalve. (J. Mater. Chem., 2011, DOI: 10.1039/C1JM10713E, Advance Article)
Efficient quantum cutting in hexagonal NaGdF4:Eu3+ nanorods: single phase, oxygen free, hexagonal NaGdF4:Eu3+ (2 mol%) nanorods with a visible quantum efficiency of 187% were prepared using an ionic liquid assisted solvothermal method. The team behind this research was led by Anja-Verena Mudring from Ruhr-Universität Bochum, Germany. (J. Mater. Chem., 2011, DOI:10.1039/C1JM10728C Advance Article)
Synthesis of magnetic hollow nanotubes based on the kirkendall effect for MR contrast agent and colorimetric hydrogen peroxide sensor: A simple solvothermal approach to synthesize hollow Mn ferrite nanostructures was developed by scientists in Taiwan. The team say that these high magnetic Mn ferrite nanotubes significantly enhance the magnetic resonance imaging contrast signal. (J. Mater. Chem., 2011, DOI:10.1039/C1JM10429B, Advance Article)
