Pocket-size food scanner

General-use, cost-effective scanning technology that can be easily adapted

07-Jan-2019

According to a study by the environmental organization WWF Germany, ten million metric tons of food are thrown in the garbage every year in Germany despite still being edible. A mobile food scanner will allow consumers and supermarket operators in the future to test whether food items have gone ...

Producing vaccines without the use of chemicals

07-Jan-2019

Producing vaccines is a tricky task – especially in the case of inactivated vaccines, in which pathogens must be killed without altering their structure. Until now, this task has generally involved the use of toxic chemicals. Now, however, an innovative new technology developed by Fraunhofer ...

Precisely fitting bone implants from the printer

07-Dec-2018

Cancerous tumors, infections or bad fractures can make it necessary to surgically remove bones and insert implants in their place. In collaboration with European partners, Fraunhofer researchers have now developed a technique with which bone implants that are precisely fitting, stable and ...

Machine learning algorithm automatically sorts zebrafish eggs

06-Sep-2018

Zebrafish possess almost all of the same genes we humans do - and that makes their eggs the perfect model organisms for use in genetic and drug research. Previously, samples have had to be prepared manually, which is a very time-consuming task. Now, however, a clever machine learning algorithm ...

Clean through solar power

03-Aug-2018

In combination with the right materials, sunbeams can work wonders: they clean building facades and decompose pollutants from the air or in the water. The magic word is photocatalysis. In practice, though, the effectiveness of this „miracle cure“ fluctuates greatly, depending on the material used ...

Marking breast implants with tomato DNA to prevent counterfeiting

02-Aug-2018

For years, a French company sold breast implants made of cheap industrial silicone components. Headline news when it broke in 2010, this scandal is still keeping the courts busy today. Now, a research team at the Fraunhofer Institute for Applied Polymer Research IAP has come up with a method to ...

New membrane reactors supply "green" raw materials for chemical industry

15-Jun-2018

In the future, closed carbon loops play an important role to drastically reduce carbon dioxide emissions and ensure safe and cost-effective access to carbon sources as the basis for products of the chemical industry. In order to increase the efficiency and thus profitability of the synthesis ...

Rapid spectroscopic process analysis

Empowers development and control of flexible production processes

12-Jun-2018

Global competition in the chemical industry, with increasingly dynamic markets and product cycles, requires shorter process development times and flexible and efficient production processes. By combining micro chemical engineering and spectroscopic process analysis in different spectral ranges, ...

Evaluating risk of hydrogen embrittlement

New simulation of cold cracks in high-strength steels

04-May-2018

High-strength steels play a vital role in the construction of modern vehicles and machines. If these steels are welded during the production of components, mobile hydrogen atoms can cause problems within the material: the atoms accumulate slowly at highly stressed areas of a component, resulting ...

Sensor the size of a nitrogen atom investigates hard drives

04-Jan-2018

Integrated circuitry is becoming increasingly complex. These days a Pentium processor contains some 30 million transistors. And the magnetic structures found in hard drives measure just 10 to 20 nanometers across – less than a flu virus at 80 to 120 nanometers in diameter. Dimensions are rapidly ...
