Get a whiff of this! A new research partnership at the National Institute of Standards and Technology (NIST) is using beams of chilled neutrons to determine how aroma compounds are embedded into assortments of other chemicals that carry and release fragrances in perfumes, detergents and other scented products.
Securing the elusive structural details could lead to what might be termed an “odor of magnitude” improvement in models for predicting interactions between fragrances and their molecular carriers. The cooperative project involves researchers from International Flavors & Fragrances (IFF), based in New York City, and NIST.
Besides contributing in other ways to product performance, carrier molecules band together and enwrap fragrance ingredients. IFF Associate Research Fellow Chii-Fen Wang likens the structural arrangement to an onion. “We want to determine where the fragrance compound is located in the onion—in the center, for example, or in a particular layer—and how the structure of the compound changes,” she explains.

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.
When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
