For the first time ever scientists use laser cooled liquid

  Whether 007 was tied to a table, or Han Solo is trapped in the Eisley bar, or any other scenes of the film will be laser as a weapon, its underlying message is that they want to target severe heat damage caused by laser. Valentino iPhone plus case

  In the real world, too, at least so far, people's impression of laser still on high heat, harmful to the human body, and more above. But now, scientists have for the first time achieved using laser cooling water and other liquids.

For the first time ever: scientists use laser-cooled liquid

  From the materials science and engineering, University of Washington researcher Peter Pauzauskie said: "in the Star Wars films, those laser cannons to the other objects to the heating effect of daily conditions and now we can use lasers to cooling water and other liquids. Prior to that, we are not sure whether a valid, because under normal circumstances, exposure to water will heat up. "

  Peter Pauzauskie and his team are using infrared laser water cooling to room temperature was 36 degrees Fahrenheit (about 2.2 degrees Celsius). According to the description of the team, in their studies successfully reversed using the laser when the laser micro-crystals in suspension in the water, emitting heat circulated by more than absorb the heat from the laser.

  In fact, microscopic crystals made the success of this high energy light crystals and crystals in the water surrounding the heat away. As early as 20 years ago, researchers at the Los Alamos National Laboratory have demonstrated this technique in a vacuum laboratory, but it hasn't been implemented in the liquid.

  If the system is able to refine and improve efficiency (current energy consumption is very high), then it will probably apply to many fields. Researchers say, theoretically, they can use any of concentrated light beam to a tiny area to cool, and maybe one day, it can even cooling process, which is very useful in scientific research.

  Pauzauskie said: "in the next cell differentiation, molecular and enzymatic functions of research, we can study their properties by cooling, perhaps we can also staged reality by laser cooling in a slow-motion movie. Its advantage is that, you don't need to cool the whole cells, thus avoiding killing the cell or condition such as changes in cell behavior. "

  Another application area is full of potential, and we can use lasers to cool the inside of the computer microprocessor, or any other part to reduce the heating effect on performance and hardware life. However, this is just one we now expect. Because we've never done a similar thing, scientists may take some time to find the reverse-best way to use lasers to cool.

  Pauzauskie also adds: "very few people would have thought to use this technology to solve the problem, because laser cooling of liquid before it is out of the question. But for other scientists and companies to the idea we have now very interested. "
