Due to the fluctuating power production and periods of peak demand, node potentials and line currents in the power grid can reach critical values which may be inacceptable for grid infrastructure. The proposed hierarchical model- based predictive control proposes optimal consumption constraints to consumers at critical times in order to secure reliability and safety of the power grid.

<b>Abstract</b>
Researchers from Goethe University Frankfurt am Main developed a new method to increase proliferation and viability of immune cells, e.g. natural killer (NK) cells, derived from patients or donors. The obtained NK cell preparations are currently tested preclinically for treatment of leukemia.

The technique, developed by researchers at the Zelinsky Institute of Organic Chemistry in a collaborative project, employs the metal palladium, which interacts…

Currently, pillow-plate heat exchangers (PPHE) enjoy growing attention and become increasingly employed in various branches of industry. The ongoing expansion of the PPHE exploitation area generates a need for new structural requirements for this type of equipment. In this regard, the flow configuration in PPHE is crucial for key aspects like energy efficiency, operating costs and functionality. Whereas in conventional PPHE the flow can be redirected by baffles made of welding lines in the inner pillow-plate channels, there is no method to improve the flow configuration in the outer channels.
For this reason, a new PPHE was developed in the group of Professor Kenig at the University of Paderborn, which enables the flow redirection also in the outer channels. A German patent application is pending, international applications are possible. On behalf of the University of Paderborn, PROvendis offer licenses to interested companies.

The magnetic coupling is capable of transmitting
torque over a hermetically separated distance as a radial magnetic coupling and at smaller dimensions as an axial magnetic coupling. An application might be in a heart catheter pump, where the maximum size is an important and a strong limiting factor.

Sensitive optical components such as semi-conductor laser diodes must be protected from back reflection. A conventional solution to this problem are Faraday optical diodes, which suffer verious problems. We offer a
novel, performant optical diode exploiting spin-orbit coupling of light.
