Scientists from the Department of Materials Science at the University of Tsukuba developed a new method to produce micrometer-scale single crystals in the form of hollow vessels. By drop-casting an ethanol solution onto a quartz substrate, the molecules can spontaneously assemble into the proper shape. This research, published in Science, may open the way for a new line of experiments in which chemical processes can be contained within these microscopic vessels.
