Scientists have discovered the solar wind like "weird cyclones"

    
Scientistcar dvr finds a mysterious turbulence from the particles in the solar wind flow and magnetic field lines do not rule change, how clear this energy change, is like a river smooth tracks flow from falling to the bottom of the waterfall formed small groups of turbulence similar to the energy changes that occur in the process. In the latest study, scientists using the European Space Agency satellite constellation vehicle dvr of two satellites in the plasma in the solar wind turbulence has been a very fine observation, where they observe are only 20 km away, along the direction of the plasma flow using "burst mode" operation to collect 450 measurements per second. Through computer simulation and control of data, scientists have determined its scope is 20 km, where they observed in turbulence boundary.

According to Italy delakalabuliya University researchers Sylvia · Cooper Mary (Silvia Perri) introduced: "this is the first time in the case of such a high resolution observation of the solar wind plasma, and found that it is a highly structured, through high resolution observations, we can reveal hidden acts of similar micro-turbulence. Sylvia · Cooper, Lisa is the first author of the research paper. European Space Agency satellite constellation in Earth covering the huge magnetic sheath around region region 100 kilometres of detection, magnetic sheath outer area is considered tovehicle dvr be in a planetary magnetic field of thin layer, under the impact of the solar wind can create a bow shock wave.

At the same time, scientists also detected in these turbulent boundary "magnetic reconnection", is a spontaneous magnetic field lines close to each other and rejoin signs have emerged, which may create a strong energy in the process. Although scientists have yet to discover these new small scale magnetic field lines back links, but they believe that the observed falling like a waterfall of energy is to maintain the main energy of the solar wind at high temperature. Sun probe from the European Space Agency and United States NASA Solar Probe's next task will be closer to the sun position detection of whether there is a similar reaction, while United States NASA magnetospheric multiscale mission of research and development will continue to clearly detect magnetic fields on a smaller-scale re-connected region.

Of the European Space Agency satellite constellation group results show that total mission accomplished on space exploration of physical phenomena, in this case, will open car dvrto a greater extent the instrument's measurement capability. Future tasks will be orbiting detectors on the plasma micro-phenomena for more complex studies, observation satellite constellation group for us to provide a better environment.

Stanford University invented the peel and stick solar panels

According to foreign media reports,mobile dvr scientists at Stanford University invented the peel and stick solar panels, the new solar panels can be stripped down like a bandage stuck to any surface, it can provide general solar panels the same size and power, it is important, the solar panels do not require any Assembly, significantly broadens the range of potential car dvr applications of solar technology.

Introducing articles about it have been published in a recent scientific report (Scientific Reports).

At Stanford University, Zheng Xiaolin (Xiaolin Zheng, transliteration) explained that this new technology is a silicon, silica and metallic "sandwich" structure.

In order to split solar cells from thin, delegation of water sheet must be at room temperature, vehicle dvr thermal release tape slowly out, let water run into the nickel and silicon dioxide interfaces, solar cells will slowly away from the rigid sheet, but are still attached to the thermal release on tape.

Cheng said that this experiment has shown that the peel and stick process does not affect the efficiency of solar cells. "And do not waste Silicon slice is not only not damage but also very clean, solar cell separation, it can be used repeatedly. Solar cells you can now be stuck to the helmets, mobile phones, convex Windows, portable electronic equipment, clothes and other things. ”

Researchers also stated that this process can be used in thin-film electronic devices, includingmobile dvr printed circuit boards, ultra-thin transistor liquid crystal displays. "It is clear that thin film electronic devices and combination of thin-film solar cells made from smart clothing to the many new products for new aerospace systems there is a realistic possibility. ”
