A functional hybrid ink for 3D-printed hydrogels is developed by Shlomo Magdassi from the Hebrew University of Jerusalem, Yi Long from Nanyang Technological University, and their colleagues. Their simple approach enables the printing of smart materials with high flexibility.

A team of researchers combine atomic resolution imaging and spectroscopic techniques to determine the structure of misfit dislocations in a perovskite-type heteroepitaxial system. The results shed light on the complex chemical behavior of misfit dislocations formed at the interface between two multinary oxides.
