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…

BaBeDa is a passive energy self-sufficient data logger for detection and documentation of shock events. A piezoelectric element is used as an acceleration sensor, since it – depending on the magnitude of the acceleration – produces electrical signals during a shock. These electrical signals are used both as a measurement signal and as power source for the circuit, which stores the data concerning the shock event. BaBeDa can be used in particular for shock detection in shipping. In the packing stations and logistics centers each BaBeDa chip can be read out to determine whether a packet was transported properly or not.
For this purpose BaBeDa can already be integrated into a packing during its production. Multiple usage is possible. Since BaBeDa is energy self-sufficient, there are no restrictions on the use of time. Because of the simple technique BaBeDa is compact, suitable for mass production and therefore also very cost effective.

The use of silicon as anode material promises high theoretical energy density in lithium-ion batteries. However, the volume of a silicon-based anode may increase substantially during lithiation. In order to solve this problem, scientists at the Institute of Photovoltaics (ipv), University of Stuttgart, now succeeded in developing a method for producing micro-stabilized and porous silicon anodes by means of laser irradiation. The battery electrodes related to this invention offer a high potential for lithiation and at the same time improved mechanical stability. Due to a large active surface they provide high energy density. They can be used for the production of mechanically flexible batteries.
