Hsu, Li-Yun; Gomez Melo, Santiago; Vazquez-Martel, Clara; Spiegel, Christoph A.; Ziebert, Falko; Schwarz, Ulrich S.; Blasco, Eva, 2024, "Alignment and Actuation of Liquid Crystals via 3D Confinement and Two-Photon Laser Printing [data]", https://doi.org/10.11588/data/CHNSX7, heiDATA, V1
Liquid crystalline (LC) materials are especially suited for the preparation of active 3D/4D microstructures using two-photon laser printing. To achieve the desired actuation, the alignment of the LCs has to be controlled during the printing process. In most cases studied to date,...
