  剑桥大学印度裔女科学家Suchitra Sebastian在Google的年度峰会“Solve for X”上提出自己已经有足够证据表明,可以通过设计的方法来找到新型的超导材料。这种方法不同与过往的碰运气的方法。

  在Suchitra Sebastian看来,从已有的超导材料中可以发现这样的一个规律,就是那些导电性不好或者绝缘体才有可能成为超导体,按照这样的规律,她通过改造一些磁性材料,并增加压力,结果令这些磁性材料成为了超导体。

  依据这样的成果,她认为现在正是一个新材料世纪到来的黎明时刻,并将引发如同工业革命那样的新技术革命。这意味着她对室温超导材料的即将问世充满了信心!

  Suchitra Sebastian talks at Google's 'Solve for X' event

  

  King's Fellow Suchitra Sebastian talked about her proposal to create a new generation of superconductors at the 'Solve for X' summit last week in Cordevalle, California.

  Entrepreneurs and scientists from around the world gathered at Google's annual summit to discuss invited 'moonshot proposals'. These are radical ideas for how groundbreaking technology can solve global problems.

  Suchitra highlighted the problem of efficiently transmitting and storing electricity from the remote parts of the world, where renewable energy is generated, to the population centres of the world.

  Exotic materials known as 'superconductors' can transport and store energy losslessly, but they only function at temperatures less than -100潞C.

  Suchitra's solution is to create new superconducting materials that work at higher temperatures. While thus far all known superconducting materials have been found by accident, Suchitra has found a way to create new superconductors by design.

  She has discovered a technique to create new superconductors from insulators or poor conductors by applying large external forces to them. In this way, we can develop a new generation of superconductors that work at higher temperatures. She explained the promising work she has already done on this, where she has been able to transform an existing magnetic material into a new superconductor.

  "What we are witnessing", she says, "is the dawn of a new materials era, and it's going to lead to a revolution which will surpass even the Industrial Revolution."
