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.

On the way to an intelligent laboratory, physicists from Innsbruck and Vienna present an artificial agent that autonomously designs quantum experiments. In initial experiments, the system has independently (re)discovered experimental techniques that are nowadays standard in modern quantum optical laboratories. This shows how machines could play a more creative role in research in the future.
We carry smartphones in our pockets, the streets are dotted with semi-autonomous cars, but in the research laboratory experiments are still being designed by...
What enables electrons to be transferred swiftly, for example during photosynthesis? An interdisciplinary team of researchers has worked out the details of how...
For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.
Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...
At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.
Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
