Front Cover: A new device that allows the mass production of four-layered macromolecular particles and fibers is invented. This electrohydrodynamic device, which contains four coaxial nozzles that simultaneously deliver four polymer solutions under an applied voltage, can revolutionize the concept of polypharmacy and biomedical engineering applications. Further details can be found in the article by S. Labbaf, H. Ghanbar, E. Stride, and M. Edirisinghe* on page 618.
