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…
We present light-emitting electrochemical cells based on hybrid lead halide perovskite nanoparticles. The latter are not oxygen sensitive and therefore the LEECs can be produced from solution or by spraying. The resulting LEECs are characterized by a four layer structure. They feature moderate luminance (> 2 cd/m2) and efficacies (> 0.02 cd/A), but high stabilities even after keeping
the devices under ambient conditions.
These eruptions on the sun eject radiation in all directions. The strongest solar flares can impact the ionized part of Earth's atmosphere – the ionosphere -…
A set of novel platinum (IV) oxaliplatin derivatives that are tumour-targeted through albumin binding have been synthesized and tested in vitro and in tumorigenic mice, with highly promising results.
Water vapor becomes liquid under 100 degrees Celsius – it condenses. Physicists speak of a phase transition. In this process, certain thermodynamic…

The SuperKEKB particle accelerator at the KEK research center in Japan has recently reached a major milestone: electrons and positrons have been circulated for…
The researchers led by Prof. Dr. med. dent. Sven Reich developed a scanning aid that replaces the conventional retaining-plate for the extra-oral scanning. The scanning aid now provides the intra-oral scanner a structure around the implant abutment. Thereby, the abutment can be extra-orally optically molded with an intra-oral scanner for the first time. The intra-oral data and the extra-orally gained records using the scanning aid are then fused together. For this end, the scientists have developed an own software.
The target of a much shorter course of treatment with a single session on the patient instead of two to four sessions is made possible by means of the scanning assistant, without the necessity of expensive laboratory scanners. This allows the much quicker method for both the doctor and the patient, and keeps a consistent quality with significant savings of financial resources.
A patent application has been filed at the European Patent Office. A functional prototype has been developed and tested with various available intra-oral scanners. The scanning assistant is the subject of further developments of the Department of Prosthodontics at the University Hospital of Aachen.
PROvendis offers on behalf of the University Hospital Aachen, licenses to the invention for interested companies.
Humyd® is an easily manageable and transportable preparation to improve the essential soil properties, which is usually applied in a pelleted form.
Novel substances are selective ligands which selectively inhibit PPAR receptors of the beta/delta subtype (PPAR: peroxisome proliferator-activated receptor) are offered for product develop-ment. The three well-known PPAR subtypes alpha, beta/delta and gamma regulate upon activation by ligands the activity of their respective target genes.
According to the study, planets with gaseous atmospheres that lie very close to their host stars are bombarded by a torrent of high-energy radiation. Due to…
