Researchers have demonstrated a new level of optical isolation necessary to advance on-chip optical signal processing. The technique involving light-sound interaction can be implemented in nearly any photonic foundry process and can significantly impact optical computing and communication systems.
Quantum computing could outsmart current computing for complex problem solving, but only if scientists figure out how to make it practical. A research team is investigating new materials that could become the basis for such an advance.
The movement of atoms through a material can cause problems under certain circumstances. Atomic-resolution electron microscopy has enabled researchers to observe for the first time a phenomenon that has eluded materials scientists for many decades.
A new study illustrates the complexity of the toxicity pattern for plants exposed to silver nanoparticles, the necessity of monitoring several markers to accurately evaluate the toxicity, and the interest of interpreting the toxicity pattern in light of the distribution and speciation of silver.
