Photoautotrophic organisms use solar radiation to carry out metabolic processes. Phototrophs store the produced energy as chemical energy by the formation of chemical bonds. Most of the photoautotrophic organisms also perform photosynthesis and convert carbon dioxide into organic material (e.g. sugars and fats). Therefore they can be used for the industrial production of biomass. Biomass production has become increasingly interesting in the biofuel or food industry.<br><br> <strong>Technology</strong><br> A highly efficient photobioreactor for growing and harvesting photoautotrophic organisms like the cyanobacterium Synechocystis sp. PCC6803 is presented. The photobioreactor has a gas-tight transparent housing, a gas exhaust and at least two compartments containing the photoautotrophic organisms and the nutrient solution for the phototrophs, respectively. The nutrient solution consists of a highly concentrated mineral carbon medium (e.g. sodium hydrogen carbonate solution) which acts as buffer medium at the same time. The photosynthetic compartment containing the phototrophic organisms is a thin layer (~ 10 mm) which is separated from the nutrient solution by a transparent semipermeable membrane. Thus, the diffusion of the nutrient solution into the photosynthetic compartment creates no turbulences as it would be in case of bubbling CO2 through the bioreactor. This diffusive feeding process results in high growth rates and efficient biomass production. <br><br>

The Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP has been developing various applications for OLED microdisplays based on organic semiconductors. By integrating the capabilities of an image sensor directly into the microdisplay, eye movements can be recorded by the smart glasses and utilized for guidance and control functions, as one example. The new design will be debuted at Augmented World Expo Europe (AWE) in Berlin at Booth B25, October 18th – 19th.
“Augmented-reality” and “wearables” have become terms we encounter almost daily. Both can make daily life a little simpler and provide valuable assistance for...
With the help of artificial intelligence, chemists from the University of Basel in Switzerland have computed the characteristics of about two million crystals made up of four chemical elements. The researchers were able to identify 90 previously unknown thermodynamically stable crystals that can be regarded as new materials. They report on their findings in the scientific journal Physical Review Letters.
Elpasolite is a glassy, transparent, shiny and soft mineral with a cubic crystal structure. First discovered in El Paso County (Colorado, USA), it can also be...
For the first time, Fraunhofer IKTS shows additively manufactured hardmetal tools at WorldPM 2016 in Hamburg. Mechanical, chemical as well as a high heat resistance and extreme hardness are required from tools that are used in mechanical and automotive engineering or in plastics and building materials industry. Researchers at the Fraunhofer Institute for Ceramic Technologies and Systems IKTS in Dresden managed the production of complex hardmetal tools via 3D printing in a quality that are in no way inferior to conventionally produced high-performance tools.
Fraunhofer IKTS counts decades of proven expertise in the development of hardmetals. To date, reliable cutting, drilling, pressing and stamping tools made of...
At AKL’16, the International Laser Technology Congress held in May this year, interest in the topic of process control was greater than expected. Appropriately, the event was also used to launch the Industry Working Group for Process Control in Laser Material Processing. The group provides a forum for representatives from industry and research to initiate pre-competitive projects and discuss issues such as standards, potential cost savings and feasibility.
In the age of industry 4.0, laser technology is firmly established within manufacturing. A wide variety of laser techniques – from USP ablation and additive...
Every three years, the plastics industry gathers at K, the international trade fair for plastics and rubber in Düsseldorf. The Fraunhofer Institute for Laser Technology ILT will also be attending again and presenting many innovative technologies, such as for joining plastics and metals using ultrashort pulse lasers. From October 19 to 26, you can find the Fraunhofer ILT at the joint Fraunhofer booth SC01 in Hall 7.
K is the world’s largest trade fair for the plastics and rubber industry. As in previous years, the organizers are expecting 3,000 exhibitors and more than...
