Petrobras announced last week that it plans to use laser beams to measure wind speed and direction. The idea is that these data will be used to improve the operation of the wind turbines maintained by this state-owned company in North Rio Grande do.The total investment of the 2.0 version of this device reaches R $11.3 million, known as the offshore wind assessment remote buoy.This technology can a...
Recently, the Advanced Laser and Optoelectronic Functional Materials Department of the Shanghai Institute of Optics and Precision Mechanics, Chinese Academy of Sciences, has made new progress in the corrosion mechanism of alkali aluminophosphate glass. The research findings were published in The Journal of Physical Chemistry C under the title "Formation Mechanism of Crystal Phase during Corrosion ...
According to the Physicists' Network, scientists from Lawrence Livermore National Laboratory (LLNL) in the United States ingeniously combined the high-power laser emitted by the National Ignition Facility (NIF) with the ultra light metal foam to create the brightest X-ray ever. These ultra bright high-energy X-rays play an important role in many research fields, including imaging of extremely dens...
Researchers from Annamarai University in India and South Ural State University in Russia reported a comparative study of resistance spot welding and laser spot welding of ultra-high strength steel for automobiles. The related research was published in The International Journal of Lightweight Materials and Manufacturing under the title "A comparative study on resistance spot and laser beam spot wel...
Scientists from the Institute of Automation and Control Process at the Far East Branch of the Russian Academy of Sciences described the changes on the surface of monocrystalline silicon during laser processing. The author of this study placed the crystal in a methanol solution and applied a laser pulse lasting one thousandth of a second to the sample, with a pulse count ranging from five to fifty ...
