Bio-concrete and biogenic construction materials with cyanobacteria

Transitioning to climate-friendly construction

02-Jul-2024 - Fraunhofer researchers have developed a method of creating biogenic construction materials based on cyanobacteria. The bacteria multiply in a nutrient solution, driven by photosynthesis. When aggregates and fillers such as sand, basalt, or renewable raw materials are added, rock-like solid ...

Effective metal extraction with electron-stimulated microorganisms by bioleaching

25-Jul-2022 - Researchers are working on solution for the economical consumption of resources, their recycling and the future recovery of new raw material sources, as well as on an environmentally friendly but still demand-oriented extraction worldwide. The extraction of heavy metals from their ores with the ...

Effective metal extraction with electron-stimulated microorganisms by bioleaching

14-Jul-2022 - As part of the project "BioIntElekt" (Development of an innovative small-scale, low-energy electron beam source integrated in a bioreactor system, funding reference: 601015) funded by the Fraunhofer-Gesellschaft in an internal program, metals should be mobilized with the help of bacteria. At the ...

The reduction of so-called "dead lithium" is an essential key to increasing efficiency in batteries

07-Apr-2022 - The development of resource-efficient manufacturing processes for next-generation battery anodes was the aim of the joint project „nextBatt“ funded by the German Federal Ministry of Education and Research (BMBF). At the Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma ...

New applications for multicolor OLED microdisplays

"We can now offer ultra-low power OLED microdisplays that not only display simple information in yellow, but also convey additional information in the signal colors red and green"

21-Dec-2021 - Scientists at the Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP have succeeded in realizing a multicolor OLED microdisplay that consumes the lowest power of all available microdisplays with an extended range of applications compared to monochrome displays. ...

Thermal storage for the energy transition

The energy is not stored in the form of increased heat but in the form of a chemical state

05-Oct-2021 - In Germany, 55 percent of final energy consumption goes towards heating and cooling. However, a lot of heat dissipates unused because it is not generated as and when required. Thermal storage using zeolite material allows heat to be stored for long periods of time without losing any. Fraunhofer ...

Porous silicon layers for more efficient lithium-ion batteries

06-Sep-2019 - The Fraunhofer FEP has developed coating processes for industry for several years. Recently in the project PoSiBat, Fraunhofer FEP scientists were able to develop a non-toxic and efficient manufacturing process for porous silicon layers. The results of the recently completed project will be ...

OLED integration in textiles: functional and eye-catching

12-Sep-2018 - Organic light-emitting diodes (OLED) are mainly known from televisions and smartphone displays. They can be used as lighting objects in car tail lights or lights. The Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP as a partner for customer-specific OLED ...

New technology for ultra-smooth polymer films

29-Jun-2018 - The Fraunhofer FEP has succeeded in developing a new technology for the production of ultra-smooth polymer films as part of the "OptiPerm" project. This project received funding from the European Union and the Saxony State Ministry of Economics, Labor and Transport. The technology, which was ...

Surface modification using accelerated electrons

Fast, gentle, precise, stable and durable

16-Feb-2018 - Surfaces must satisfy a wide range of requirements: they need to be decorative, and even contribute substantially to hygiene. They also play a large role in biomedicine. There are numerous processes for functionalizing surfaces, depending on the application. Many are already well established and ...
