Beijing April 28 news, according to foreign media reports, in many science fiction and "007" film, laser as a weapon can kill the enemy, the destruction of the planet. However, according to Dr. Adrian Quarterman, a scientist from Scotland in the United Kingdom, although lasers may be used as weapons in the future, he hopes that lasers can be used to provide energy for the earth in the future. According to the British "The Times" report, Dr. Adrian Quarterman from the University of Dundee, England, he is studying the method of converting sunlight into laser energy.
Space Lasers, a Scottish scientist, Adrian Quarterman, believes that lasers can be used to provide energy for humans. But compared to Star Wars, the laser energy used here is much smaller.
Scientists at the Tokyo Institute of Physics and Chemistry in Tokyo hope to install laser equipment at the International Space Station to clean up space debris.
In his view, in order to achieve this kind of transformation, it is first necessary to launch satellites that orbit the earth. Then, the satellite collects sunlight through the installed mirror and converts it into laser light. Finally, satellites use semiconductors to transmit energy back to Earth in the form of lasers.
If Dr. Adrian Quarterman's idea can be realized, it means not only that the British Scotland can use solar energy, but also means that humans can quickly restore the electricity supply in the disaster area. He told the Times that “by adopting the method I proposed, the laser can be directed at the corresponding solar panel, which will greatly increase the energy received by the panel.†Previously, Dr. Adrian Quarterman has successfully completed in Scotland, United Kingdom. For the first experiment, he now hopes to conduct experiments in Portugal.
Unlike movies, the lasers used by Dr. Adrian Quarterman could not only destroy the planet, they couldn't even confuse the pigeons.
In fact, there are many different ideas about the application of lasers. Last week, scientists at the Tokyo Institute of Physics and Chemistry in Tokyo proposed different ideas in a paper. They hope to install laser equipment at the International Space Station to clean up space debris. They believe that the space station’s existing telescopes can be used to find and locate space debris (up to 100 km). Then, using lasers to emit strong pulses forces space debris into the atmosphere, causing space debris to burn in high-speed friction with the atmosphere. The energy of this kind of laser device is also very small. It can only achieve a target of less than 1 cm and is not enough to be a space weapon.
However, this does not mean that space lasers are absolutely safe. Dr. Quarterman himself admitted that we cannot allow anyone to control these satellites.
Hydroxypropyl Methylcellulose Methoxyl content: With the reduction of methoxyl content, gel point raise up, water solubility reduce, surface activity decrease.
hydroxypropyl methylcellulose Methoxyl is White or similar to white powder, odorless No heat, chemical inertness, and not participate in the metabolism of human body.
hydroxypropyl methylcellulose Methoxyl HPMC used in Construction:
- Used as the water retaining agent and retarder in mortar to make it has good pumpability.
- Used as adhesives in plaster, gypsum material, putty powder or other construction materials to improve its workability and extend the operation time.
- Used as paste enhancer of ceramic tile, marble and plastic decoration and reduce usage of cement.
- HPMC water retention property can prohibit too fast dry and cracking after the slurry spraying and enhanced strength after hardening.
