The dispersion and reaction of two immiscible liquids with subsequently separation of the products according to the state of the art need several steps. The invention enables process intensification, the dispersion, reaction and separation of two immiscible liquids in one device in one batch process. The core of the invention is a rotatable reactor with an integrated centrifuge. Thus the invention enables equipment reduction of separate mixing and separation devices. Depending on how the motors run towards another, a mixing or a centrifugal effect is produced. Competitive Advantages:
•Compact and cost effective
•Mixing and Separation in one device
•Complete control on measurements parameters
•Variable energy input
•Quantitative results
•Short contact times also with coalescence inhibited substance Systems
•No back-mixing
Current Status: A patent application for this invention has been filed in Germany. On behalf of the RWTH University, PROvendis is seeking a partner for further development in view of licensing the Technology.
The characterization of sedimentation and coalescence processes in a multi-phase system is a crucial step for the design and development of equipments for phase dispersion and separations. An established model of phase separator is based on the application of a gravitational field on the multiphase system. For those kinds of equipments, an early system characterization is possible thanks to suitable procedures and instruments established at laboratory-scale.
An effective alternative to gravitational separators are annular centrifugal contactors. Those equipments offer a better scalability and flexibility respect to the gravitational separator. Furthermore, they provide a versatile solution as phase separators as well as chemical reactors. Although centrifugal contactors are already established at the industrial level, a pre-characterization of the systems of interest in small equipment is not possible with the existing technologies. Competitive Advantages:
•Compact and cost effective
•Enables pre-characterization al lab level for processes in centrifugal contactors
•On-line camera
•Complete control on measurements parameters
•Quantitative results

Device and method of treating objects & bulk materials with a physical plasma cushion at atmospheric pressure. The plasma passes from the discharge chamber to the treatment chamber through a sparger plate comprising a multitude of holes, producing a plasma cushion, which supports & slides/pushes the objects while treating them.
Mechanical elasticity is a central parameter of living cells and tissues. Cancerous and healthy tissues, for example, have a different elasticity. Therefore, tools are under development to make tissue elasticity a new diagnostic marker in medicine1. Nevertheless, these efforts have been hampered by poor spatial resolution (i.e. ultrasound elastography) or by their usability being restricted to an in vitro environment (i.e. scanning ion conductance microscopy2,3,4 (SICM)).
Here, we present a novel instrument which transfers principles of SICM into the macro-environment of endoscopy or laparoscopy. This opens the door for a real-time measurement of tissue elasticity, e. g., during minimally invasive surgery.
Our handheld device uses the pressure of a water jet for inducing a deformation of the outer surface of any given tissue. The resulting change in a simultaneously recorded ion current between two electrodes on the “water nozzle” renders charac-teristic parameters for the elasticity of the tissue.
Many Gram-positive bacteria such as are significant pathogens of both animals and humans. Reliable detection of hemolytic activity is a cornerstone for diagnosis of the pathogenic properties of these bacteria.
Here an improved diagnostic test that enables reliable detection of pathogenic Gram-positive bacteria by enhancing hemolytic zones on blood agar plates is presented.
The present invention generally applies to the fixation of hollow organs such as the stomach or the baldder to an outer structure, e.g. to the abdominal wall. The main field of application is in particular the percutaneous endoscopic gastrostomy (PEG) sonde.
PEG-sondes are applied by various techniques, especially by the so-called pull-through and the direct punctation (or push) technique. The latter is predominantly applied, when a stenosis of the upper gastrointestinal tract by a tumor prohibits oral access due to the consumption of space, but also due to the fact that the pull-through method is discussed in the literature to cause inoculation metastasis.

Shar-Pei Autoinflammatory Disease (SPAID) is a complex inflammatory disease. Typical signs are recurrent bouts of fever, inflammations of the ear, arthritis and a reddened skin. The dogs can also develop amyloidosis. Scientists at the University of Veterinary Medicine Hannover developed a genetic test for SPAID predisposition.
Oncolytic virotherapy for cancer has emerged as a novel and promising therapeutic approach to replace standard cancer therapies, which often provide limited efficacy at the cost of unpleasant or severe side effects. Here, a novel VSV/NDV hybrid virus was engineered that combines the advantages of both vesicular stomatitis virus (VSV) and Newcastle disease virus (NDV) vectors, while the safety concerns of both are eliminated.
Scientists of the MEET at Wilhelms University of Muenster developed a set of alkylsilyl complexes (MOSi) as elecrolyte additive, which enhance the performance of lithium ion batteries. Previous studies have shown that electrolyte additives based on metals and semimetals (LiBOB, Mg(TFSI)2, Al(TFSI)3) as well as additives containing trimethylsiloxyl (TMS) groups as ligands can have positive impact on the cycling performance of lithium ion battery cells due to solid electrolyte interphase (SEI) and/or cathode electrolyte interphase (CEI) film forming properties and/or scavenging properties towards acidic impurities. The results of LIB full-cells show a twofold cycle life compared to the standard electrolyte. The addition of the M(TMS)x based additives lowers the charge transfer impedance during prolonged cycling. MOSi leads to lithium ion batteries with enhanced anti fading performance.
A German patent application is pending. International applications are possible.

Skyrmions are stable topological vortices in the magnetization. They can be created on surfaces of magnetic materials where they move through the materiallike a kind of hose. Their motion can be controlled with magnetic and/or electric fields or currents. Skyrmions have a diameter in the nm range and can be easily generated and also detected. SkyrMem is a novel storage arrangement that uses these properties of the skyrmions. It consists of a strip of magnetic material, about twice as wide as the diameter of a skyrmion. A potential barrier is applied in the center of the strip so that the skyrmions can only be placed above or below the line. This can be used to represent logical “1” and “0”. By applying a voltage, the scyrmions can be moved along the strip, permitting serial reading of the information.
With SkyrMem, a completely new type of digital memory can be realized. Since scyrmions are very small and nevertheless stable, storage densities above the values customary today for hard disks are possible. High readout rates can also be achieved. SkyrMem provides a technical basis for the storage media of the future.
A German patent application was filed, international applications are still possible.
