Grape harvest is at its peak now. Ripe grapes are collected and will be processed to tasteful wine. Before the liquid will be filled, the bottles need to be very clean and free of germs. Bottles and cups can be treated and disinfected with special UV radiation.
The UVC radiation, effective at wavelengths from 200 nm to 300 nm, has a strong bactericidal effect. It is absorbed by the DNA of microorganisms such as viruses, bacteria, yeasts or fungi, destroys its structure and inactivates living cells.
Bacteria are rendered harmless within seconds by UV light. If the irradiance is high enough, UV disinfection is a reliable and environmentally-friendly method because chemicals need not be added.
Moreover, the microorganisms cannot become resistant to UV radiation.
After the wine has been filled into bottles, individual labels make them look pretty and unique.
Label Printing and individualization is a big potential for digital printing applications
Printing ink needs to be completely dried or cured before the products can be labeled onto the bottles but also stacked, cut, folded or otherwise processed.
Depending on the paint or ink, UV lamps or IR emitters, or a combination of both, are used for reliable drying or curing.
The UV and IR solutions are precisely adjusted to the individual printing process requirements, to work as efficiently as possible.

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...
