Researchers pinpoint mechanism for aroma formation in wine

October 3, 2014 9:35 am | News | Comments

The majority of wines are produced from around 20 different types of grape, all of which have their own typical aroma. This is due to the terpenes, a diverse category of chemical substances including cholesterol and estrogen. Scientists have now identified two enzymes that determine the terpene content, and thus the aroma intensity, of grapes. The findings could play an important role in the future development of grape varieties.

Multi-spectra “glasses” aid studies of light elements with SEMs

September 26, 2014 11:16 am | News | Comments

Scanning electron microscopes can determine chemical compositions with the help of energy dispersive spectrometers. However, lighter elements like carbon emit secondary fluorescence in an energy range insufficiently resolved by these instruments. Physicists have developed a potential solution to this problem by adding reflection zone plate optics to a specialized spectrometer that delivers high resolution from 50 to 1,120 eV.

Researchers use FEI Titan to link plasmonics with molecular electronics

June 24, 2014 11:44 am | News | Comments

Plasmon tunneling is a quantum-mechanical effect where electrons rapidly oscillate across very closely-spaced metal structures. Using a Titan scanning/transmission electron microscope developed and made by FEI Company, the scientists were able to not only observe this new phenomenon directly, but also control the frequency of the tunneling currents by placing single layers of different molecules between the closely-spaced metal particles.
