Virginia Tech researchers are working on technologies that could create a new industry from a problem in the states cotton-growing region.
"Our goal is to add a value to the cotton crop by using the residue from the cotton to make a valuable product," said Foster A. Agblevor, professor of biological systems engineering in Virginia Techs College of Agriculture and Life Sciences.
About 100,000 acres of cotton are grown in the Virginia counties of Southampton, Isle of Wight, Greensville, Sussex, and the City of Suffolk. After the cotton is ginned, the residue left at the processing plant contains the chemical ingredients for products that are commercially valuable. Currently, the residue piles up at the site and must be removed. Because it easily ignites, it can be a hazard, and if it burns, can contribute to air pollution. "We have been able to develop the manufacturing processes that can extract specific chemicals and make two products – ethanol, which can be a fuel in automobiles, and xylitol, a sugar. "Our work shows a manufacturing process for extracting both products simultaneously from the cotton residue so in the future it is possible that a manufacturing company operating in Southside Virginia could produce both the ethanol and the xylitol products," Agblevor said.

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.
Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
