4D Biofabrication

Fig. 1. Fabrication of self-folding hydrogel-based (cell-laden) tubes via 4D bioprinting: a) printing of mathacrylated alginate or hyaluronic acid solutions; b) crosslinking of the printed films with green light (530 nm) and mild drying; c) instant folding into tubes upon immersion of the crosslinked films in water, PBS, or cell culture media; d) examples of the fabricated self-folding tubes (from right to left): schematic illustrations and representative microscope images of single tubes with/without printed cells formed through the described 4D printing process; photograph of a glass vial containing a large number of self-folded tubes, indicating on the possibility of their large-scale fabrication.

Despite water being a ubiquitous substance, it is surprising that some basic questions are still debated. Here using a combination of experimental (cryogenic STM) and theoretical (first-principle electronic structures and molecular dynamics) methods, we systematically studied the unusual structure and dynamics of water molecules on NaCl surface. More interestingly, for the first time, we observe the full quantum effect and magic number hydrates in water system. These results shed light on our understanding of water at atomic scale.
