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…
At the University of Konstanz, Germany, a new method for wiring rear contact solar cells has been developed, in particular suited for wire-based interconnection of IBC solar cells. For wiring, narrow tabbing or wire (e.g. highly conductive copper wire), which is run orthogonally to the contact fingers, is used. Half of the wires are led through very small gaps in the p contacts to connect to the n contacts. The other half is led through gaps in the n contacts, connecting to the p contacts.
Many biological processes depend on oligomeric protein-protein interactions (PPI). However, state-of-the-art in vivo PPI techniques focus on analysing binary interactions (i.e. the Split-Ubiquitin System (SUS)1). The SUS can also be used to analyse binding of three proteins in the so-called SUS Bridge Assay (SUB)2 – see Figure A. Nevertheless, this assay makes an unbiased screening approach cumbersome and its low efficiency restricts the identification of meaningful candidates.
Here, we present the first screening system in yeast that permits high-throughput screening of cDNA libraries for ternary binding partners of a known interaction couple. This is achieved by a unique combination of SUB and yeast mating. Technical prerequisites are special “2in1”-vectors3, which allow simultaneous transformation of “Bait I” and “Bait II” on a single plasmid in yeast of one mating type and the cDNA library in the other – see Figure B.
Two IT giants, Intel and HP, have entered a race to produce a commercial version of memristors, a new electronics component that could one day replace flash…
Both events are widely accepted but unproven, so geoscientists are eager for more details and better dates. Many of those dates come from zircons retrieved…
In cooperation with Italian partners, Karlsruhe University of Applied Sciences recently developed a new type of anti-fouling coating on membranes with scalable retention to improve the quality of purified water while reducing the costs involved in cleaning, maintaining and replacing the membranes. Pore sizes and thus separation efficiency and chemical properties of the novel PBM coated membrane surface can be individually adjusted to the composition of the water to be purified. The PBM coated ultrafiltration membranes were successfully tested in membrane bioreactor (MBR) systems using real wastewater.
The new Soft Switching Three Level Inverter (S3L – Inverter) is of striking simplicity and is therefore inexpensive. Because of the underlying principle, it works without losses and thus with maximum efficiency. The inverter is easily controlled, has EMC friendly inherent di/dt- and du/dt limitation, and can be built using low-cost standard semiconductors.
Field of use: electric drives, solar power inverter, wind power inverter, uninterruptible power supplies (UPS).
If you take certain atoms and make them almost as cold as they possibly can be, the atoms will fuse into a collective low-energy quantum state called a…
The invention describes a process for the production of fiber-
reinforced aluminum foam. The composite has advantages
compared to the non-reinforced foam like higher mechanical
properties and greater stiffness. By the fibers the influence of
the non-homogeneous pore distribution can be reduced. Withe
respective reinforcement fibers the energy absorption can be
increased to without increasing the global density.
