A surprising enhancement was observed in this size regime when two different materials (silver and gold) were interfaced. Through theoretical modeling and quantum-mechanical calculations, quantum effects were determined to be responsible for this enhancement by creating a stronger condition for a "charge-transfer plasmon" resonance. The insight gained about this new mechanism may suggest general strategies for overcoming losses in plasmonic performance in the quantum size regime.

Faster, smaller and more energy-efficient - that is what computers of the future should be like. A new phenomenon stands to make a major contribution in this direction: It needs 100,000 times less current than existing technologies, and the number of atoms needed for a data bit could diminish significantly.

Johns Hopkins researchers used suction to learn that individual "molecular muscles" within cells respond to different types of force, a finding that may explain how cells "feel" the environment and appropriately adapt their shapes and activities. A computer model the researchers developed also lets them predict what a cell will do in response to altered levels of those "muscles," a common occurrence in a variety of cancers.
