However ATPE has no large-scale industrial applications yet. This is based substantially on very long phase separation times resulting from low interfacial tensions and low density differences between the phases producing intensive and stable emulsions. This causes an increased footprint of the required mixer/settler devices or the application of additional equipment such as energy consuming centrifuges. The present invention relates to a process for separation or purification of biomolecules via ATPE. The advantages are maintained and the major limitation of long phase separation time is overcome by immobilizing one of the two phases in porous particles. Suspending the impregnated particles in the second aqueous phase containing the biomolecules creates the emulsion without any need for phase separation after the extraction step. During the separation process, the biomolecules partition between the aqueous phase surrounding the particles and the immobilized second aqueous phase inside of the particles’ pores.

The IPH presents a solution at HANNOVER MESSE 2015 to make ship traffic more reliable while decreasing the maintenance costs at the same time. In cooperation with project partners, the research institute from Hannover, Germany, has developed a sensor system which continuously monitors the condition of the marine gearbox, thus preventing breakdowns. Special feature: the monitoring system works wirelessly and energy-autonomously. The required electrical power is generated where it is needed – directly at the sensor.
As well as cars need to be certified regularly (in Germany by the TÜV – Technical Inspection Association), ships need to be inspected – if the powertrain stops...
When an earthquake hits, the faster first responders can get to an impacted area, the more likely infrastructure--and lives--can be saved.
The Atlantic overturning is one of Earth’s most important heat transport systems, pumping warm water northwards and cold water southwards. Also known as the Gulf Stream system, it is responsible for the mild climate in northwestern Europe.
Scientists now found evidence for a slowdown of the overturning – multiple lines of observation suggest that in recent decades, the current system has been...
Because they are regularly subjected to heavy vehicle traffic, emissions, moisture and salt, above- and underground parking garages, as well as bridges, frequently experience large areas of corrosion. Most inspection systems to date have only been capable of inspecting smaller surface areas.
From April 13 to April 17 at the Hannover Messe (hall 2, exhibit booth C16), engineers from the Fraunhofer Institute for Nondestructive Testing IZFP will be...
