Elpasolite is a glassy, transparent, shiny and soft mineral with a cubic crystal structure. First discovered in El Paso County (Colorado, USA), it can also be…

The invention presented here consists in the fact that via pow-der/air/water jet devices, induced through the special geometry of the instrument approach the cleaning powder/water jet is released in such a way that even the undercuts of the implant?s surface are cleaned effectively.

The hole in the ozone layer over Antarctica became an international cause for concern in the latter half of the 20th Century, but as EUMETSAT’s Atmospheric…

Researchers at Aalto University and Lawrence Berkeley National Laboratory have demonstrated that polaron formation also occurs in a system of magnetic charges,…

The technology enables the fast and competitive production of specific ALA via biotechnological process technology. The production of aminolevulinic acid (ALA) is the first step in the biosynthesis of tetrapyrroles and porphyrines (like Chlorophyll, vitamin B12, heme). Recently ALA has attracted interest as a selective and biodegradable herbicide and insecticide. Besides ALA can be applied in the photodynamic therapy and treatment of various kinds of cancer.
Administration of ALA in the tumorous tissue leads to a porphyrin formation inside the cells. Accumulated porphyrins generate reactive oxygene species when excited by light which can lead to death of the tumorous cell. On behalf of the University of Bielefeld, PROvendis offers access to rights for commercial use as well as the opportunity for further co-development.

By decoupling cell growth and productivity of biosynthesis the new method and associated Escherichia coli strain allow for an increase in productivity by a factor two to three.
This could not only be interesting for pharma industry, e.g. by increasing the capacity of insulation production, but for biotechnological synthesis of succinic acid as well. The demand for succinic acid as a component of plastics such as polyamides or polyesters is estimated to amount to 250,000 tons per year.

The demonstration shows that the flexibility and performance of optical networks can be maximized when adjustable transmission rates are dynamically adapted to…

A team of scientists including A*STAR researchers has captured tiny flashes of light from an ultrathin layer of organic molecules sandwiched between two…

In his Nobel Lecture on December 8, 2000, Herbert Kroemer coined the saying “the interface is the device”. Kroemer referred to the mature field of…

The energy bursts caused by the ELMs would be a detrimental event, as it can potentially damage the internal components of the fusion plasma devices like ITER….

The technique used to investigate the inner details of NGC 1052 is known as very-long-baseline interferometry, and has the potential to locate compact jet…

A new and cost saving method makes it possible to combine different components of any form. Manyfold material combinations such as carbon fiber composites and metals can be combined easily. With the material friendly technique high quality welding seams can be manufacured in a flexible manner without affecting the components global-thermally.

Scientists at the University Göttingen developed a monoclonal antibody against a biotinylable peptid (Epitope-Tag) called AP-tag or Avi Tag. This small peptide served as a substrate mimic for biotin ligase (BirA). Anti-AP antibodies are useful tools in the analysis of AP-tag fusion proteins.

An international team of astronomers using the Hubble space telescope have been able to study stellar evolution in action. They observed dramatic increases in…

A number of extrasolar planets have been found in the past two decades and now researchers agree that planets can have a wide variety of characteristics….

Materials that conduct electricity at high temperature but are insulating at lower temperatures have been known for decades. However, until recently it was not…
