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.

A novel mechanism for electron optics in two-dimensional solid-state systems opens up a route to engineering quantum-optical phenomena in a variety of materials
Electrons can interfere in the same manner as water, acoustical or light waves do. When exploited in solid-state materials, such effects promise novel...
Biochemists at Martin Luther University Halle-Wittenberg (MLU) have used a standard electron cryo-microscope to achieve surprisingly good images that are on par with those taken by far more sophisticated equipment. They have succeeded in determining the structure of ferritin almost at the atomic level. Their results were published in the journal "PLOS ONE".
Electron cryo-microscopy has become increasingly important in recent years, especially in shedding light on protein structures. The developers of the new...

Solar cells based on perovskite compounds could soon make electricity generation from sunlight even more efficient and cheaper. The laboratory efficiency of these perovskite solar cells already exceeds that of the well-known silicon solar cells. An international team led by Stefan Weber from the Max Planck Institute for Polymer Research (MPI-P) in Mainz has found microscopic structures in perovskite crystals that can guide the charge transport in the solar cell. Clever alignment of these "electron highways" could make perovskite solar cells even more powerful.
Solar cells convert sunlight into electricity. During this process, the electrons of the material inside the cell absorb the energy of the light....
