Special issue on physical-layer security
Journal of Communications and Networks, 2012 The unprecedented development of wireless networks and increased concerns for their security have fostered a renewed interest for communication schemes that ensure confidentiality at the physical layer itself. The idea that there is security to be gained by harnessing the randomness of the physical-layer with appropriate coding schemes has now evolved ...

Demonstrating Vibrational Current Generation With a Self‐Assembled Bioelectret
Advanced Functional Materials, EarlyView.Vacuum‐deposited films of the plant‐derived molecule, Baicalein, form a self‐assembled bioelectret exhibiting spontaneous orientation polarization and a giant surface potential. The films induce alternating current during the vibration of a movable electrode without charging treatments. Hydrocarbon protection enhances the air stability of the Baicalein

Advanced Functional Materials, EarlyView.A shape‐memory microneedle system enables reproductive hormone therapy through a single transdermal insertion. The X‐shaped device sustains follicle‐stimulating hormone release for three days, and mild heating restores the O shape to trigger burst human chorionic gonadotropin release.
