Young stars ejecting plasma could give us clues into the Sun’s past Kyoto, Japan — Down here on Earth we don’t usually notice, but the Sun is frequently ejecting huge masses of plasma into space. These are called coronal mass ejections (CMEs). They often occur together with sudden brightenings called flares, and sometimes extend far enough to disturb Earth’s magnetosphere, generating space weather phenomena including auroras or geomagnetic storms, and even damaging power grids on occasion. Scientists believe that when…

H₂Oleum is an absolutely stable microemulsion and the first thermodynamically stable water/fuel emulsion ever – stable over an extremely wide range of temperatures and operating conditions.
H₂Oleum is a bicontinuous microemulsion – i.e. both the oil and the water components form continuous domains within the liquid. H₂Oleum significantly saves surfactant and the water/fuel ratio can be freely varied.
We offer and licenses and technical support for the commercialisation of H₂Oleum to innovative companies.
Patent applications have been filed for H₂Oleum in Europe and North America.
A series of novel low molecular weight compounds with high activity against Plasmodium falciparum have been developed, synthesized and tested. The compounds are based on a substituted steroidal pharmacophor and are as antiinfective agents in their structure completely new.
The compounds are highly active against red blood cell stages of P. falciparum, also of chloroquine-resistant parasites. Present SAR data indicate that the hydrophobic steroid component and a hydroxyarylmethylamino group are essential for the antimalarial action of the compounds. The hydrophobic steroid part is likely to mediate membrane permeability.
A simple method to sense DNA, as well as potential biomarker proteins of cancer or other diseases such as Alzheimer’s, may soon be within reach – thanks to the…

Common free space optical communication systems use intensity modulation, which has the drawback of a low spectral efficiency. However, OMIMO is an improved concept for free space optical (FSO) communication. To enhance efficiency a coherent transmission is used with incoherent light sources.
At the transmitter a baseband signal is phase-shifted for precoding, spatial multiplexing or beam forming. After upconversion of the baseband signal to a bandpass signal a DC-offset is added. This signal drives a light source, e. g. an LED or a laser diode by direct modulation. The receiver works with a reverse scheme. For transmitting and receiving a plurality of light source and photo detector can be used in parallel, respectively, to establish an optical MIMO concept.
2STEP-CP is a method of communication between two (mobile) signal sources and a relay station with two antennas. In a first time slot, the two signal sources send a first signal, respectively, in a second time slot a second signal. Based on the respective first and second signals the relay station generates a first and a second network-coded signal. In a third time slot, the first network-coded signal is sent via the first antenna and the second network-coded signal is sent via the second antenna. In a fourth time slot, the two network-encoded signals are sent via the respective other antenna. Based on the signal the signal sources have sent in the first two time slots, both signal sources are able to decode the network coded signals from the relay station. The process is also adaptable to a higher number of signal sources and antennas per relay station.
