Coalescence of Ag2S and Au nanocrystals at room temperature: A method to extract gold from quantum dot–gold hybrids or gold-containing alloys could provide an effective route to investigate the influence of gold on the properties of these materials say scientists at the Institute of Process Engineering, Chinese Academy of Sciences. The strategy is based on a dissolution–renucleation process which leads to the coalescence of Ag2S and Au nanocrystals. (J. Mater. Chem., 2011, 21, 11750-11753)
Ceramic nanowrinkles via a facile replication process: Researchers at RWTH Aachen University, Germany, have developed a simple method for fabricating regularly structured ceramic nanopatterns without any lithographic or mechanical processes. Their approach uses a molding and replication process to create the wrinkled ceramic nanopatterns. (J. Mater. Chem., 2011, 21, 11750-11753)
A versatile approach to achieve quintuple-shape memory effect by semi-interpenetrating polymer networks containing broadened glass transition and crystalline segments: A shape memory polymer that remembers 5 different shapes has been developed by Chinese scientists. The quintuple-shape memory effect is achieved using PMMA/PEG semi-interpenetrating polymer networks containing broadened glass transition and crystalline segments. The team that this is the first time a quintuple-shape memory effect has been achieved. (J. Mater. Chem., 2011, DOI:10.1039/C1JM12496J, Advance Article)
