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.
No more error-prone evaporation deposition, drop casting or printing: Scientists have developed organic semiconductor nanosheets, which can easily be removed from a growth substrate and placed on other substrates.
Researchers have developed a new approach for studying piezoelectric materials by using ultrafast 3-D X-ray imaging and computer modeling. Their integrated approach can help us better understand material behavior and engineer more powerful and energy-efficient technologies.
Control of light-matter interaction is central to fundamental phenomena and technologies such as photosynthesis, lasers, LEDs and solar cells. Researchers have now demonstrated a new class of artificial media called photonic hypercrystals that can control light-matter interaction in unprecedented ways.
