In defending her PhD thesis, Teresa Garde Cerdán, Doctor in Chemical Sciences at the Public University of Navarre, stated that the maximum concentrations of compounds transferred to wine from wood is reached after 10 to 12 months of the wine being stored in wooden casks.
Moreover, it has been shown that, after a year, the concentration of these compounds, positive for the aroma of the wine, not only do they not increase but, in some cases, they begin to decrease. This is an important finding given that the current norms lay down a minimum period of twelve months for Reserva wines and 18 months for Gran Reserva ones.
The PhD thesis, defended at the Public University of Navarre under the title, "A Study of the Volatile Composition of Red Wines Aged in Different Kinds of Oak Casks".

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...
Breakthrough provides a new concept of the design of molecular motors, sensors and electricity generators at nanoscale

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
Theoretical physicists propose to use negative interference to control heat flow in quantum devices. Study published in Physical Review Letters
Quantum computer parts are sensitive and need to be cooled to very low temperatures. Their tiny size makes them particularly susceptible to a temperature...
