Stemming the loss of precious wine
When you buy a bottle of wine for the holidays, you are actually paying for more than a bottle. That’s because during the months or years that the wine was aging, as much as 15 percent of it was lost to evaporation.
Now, that loss of good wine can be prevented -- and wine prices reduced -- with an atomizer system that keeps the humidity inside and outside the barrels equal, thereby eliminating the evaporation that occurs as nature works to maintain equilibrium.
The system, developed at a Technion-Israel Institute of Technology incubator company, consists of three main components for the wine cellar: an acceleration chamber that uses air at supersonic speed to atomize water into a "dry fog" of droplets so small they evaporate before reaching the ground (that means no water collects on the wine barrels or the floor on which the barrels sit, preventing mold); a computer controlled sensor that maintains humidity at 95-98 percent, reducing evaporation of wine from the barrels to about 1 percent; and a gauge that measures humidity levels up to 100 percent, a feat beyond current gauges which stop at 90 percent.
"High humidity is often confused with wetness, but the two are not the same," said Eran Brown, general manager of Optiguide, the Technion company that developed the atomizer system. "Destructive mold on barrels and on the floor forms when there’s freestanding water but not in extreme humidity, which saturates the air but doesn’t wet the barrels and floor."
Optiguide’s internationally patented system is already in use at wineries in Israel, Spain, Portugal, Italy, Mexico and Chile. The company is now searching for U.S. marketing representation in preparation for sale in the United States.
The Technion-Israel Institute of Technology is Israels leading scientific and technological center for applied research and education. It commands a worldwide reputation for its pioneering work in computer science, biotechnology, water-resource management, materials engineering, aerospace and medicine. The majority of the founders and managers of Israels high-tech companies are alumni. Based in New York City, the American Technion Society is the leading American organization supporting higher education in Israel, with more than 20,000 supporters and 17 offices around the country.

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.
Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
