Detecting effects of 3D shapes in nanoscale chip features
Researchers have determined that, at the ultra-small scale of the latest chip features, SEM measurements are strongly affected by variations in the gate's three-dimensional shape that can occur in the course of fabrication, including the line width and center position, the angle formed by a raised feature's sidewalls, the curvature radius of the top edge area, and the effect of adjacent structures.

Read moreResearch seeks alternatives for reducing bacteria in fresh produce using nanoengineering
Researchers have been exploring natural, safe and alternative antimicrobials to reduce bacterial contamination. Plant essential oils such as those from thyme, oregano and clove are known to have a strong antimicrobial effect, but currently their use in food protection is limited due to their low solubility in water. The team explored ways to formulate oil nanoemulsions to increase the solubility and stability of essential oils, and consequently, enhance their antimicrobial activity.
