Two intelligent labels were developed to monitor the time and temperature of frozen products and to monitor the oxygen content in modified atmosphere packed fresh chilled food. The food producer, transporter, retailer and consumer can see with a change of colour of the smart label if the food has been stored at too high temperature and consequently if the food is prematurely spoiled.
Controlling the post production life cycle of food is an important element of food supply chains. Improper handling of product during transport, storage and in households results in quality defects, increases risk of microbial growth, subsequent spoilage and increases wasting of food.
TTI based on an enzymatic reaction inform the consumer about the quality of the products using a green-orange-redlight system.

Previous investigations showed that there are still many unexploited application areas for time-temperature monitoring using smart labels. In the IQ-FRESHLABEL project, novel intelligent labels for indication of temperature abuse of frozen foods were developped.
These smart labels have to meet demands specific to frozen food. Products have very long shelf-life of 18 to 24 months at optimal storage temperature of -18°C. Increase of temperature lead to major quality deterioration, even if temperature stays below 0°C.
“Smart labels for frozen fish products are validated in Greek cold chain and ready to be implemented on the market. It is possible on a unit base to monitor the quality of the food products in terms of respect of the optimal storage temperature along the cold chain – an obvious benefit for the consumer”, says Marie Shrestha, project manager at the independent research institute ttz Bremerhaven.
Leakages in chilled poultry products packed under modified atmosphere lead to change of the gas atmosphere and thus the shelf life of a product is decreased by 26% for example for a leakage with 0.2mm diameter. A novel, cheap and non-destructive quantitative oxygen detection system, using luminescence technology was created to detect leakages in MAP food (detection range 0-30% O2) and inform about subsequent potential premature spoilage of the food product.
The socio-economical impact of the integration of the smart labels in different food chains was studied in Finland, Germany, Southern France, and Greece. Food manufacturers, retailers and consumers see benefit in implementing intelligent labels. Consumers consider that products with TTI are of higher quality than the ones without and are willing to pay 20 cents more for TTIs (n=2525 consumers interviewed).
Participating food, packaging and consumer associations promoted the influence of smart labels application on waste reduction, food quality and safety in the European supply chains in Greece, Finland, Norway, France, Romania and Poland. Consumers considered that TTIs would assist them to handle food products in adequate manner (n=2525).
IQ-FRESHLABEL is a research project, partly funded by the European Commission in the 7th Framework programme. The project was running for three and a half years (1st August 2010 to 31st January 2014) with 17 partners from 9 different countries.
ttz Bremerhaven is an independent research institute and performs application-related research and development. Under the umbrella of ttz Bremerhaven, an international team of experts is working in the fields of food, environment and health. ttz has assisted enterprises of all sizes for over 25 years in the planning and implementation of innovation projects and the corresponding acquisition of funding at national and European level. http://www.ttz-bremerhaven.de

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
