Invention of Superconductors Turns 100

john April 12, 2011 No Comments
Superconductors It has been a century since the discovery of Superconductors. The discovery was made by Heike Onnes on April 8th, 1911 at the Leiden Cryogenic Laboratory in Netherlands. The first experiment involved the immersing of a mercury capillary in liquid helium. In this experiment, Heike Onnes noticed the resistance of the mercury dropping to zero as soon as the temperature reaches 3 Kelvin’s or 3 degrees above absolute zero temperature. This was the first phenomenon which clearly showed...

Direct Conversion of Solar Energy into Fuel

john April 1, 2011 5 Comments
The concept of transforming solar energy directly into fuel is not easy. The method was tried out by researchers for the past decade and many prototypes were developed. But all the past attempts had some basic problems like life span, cost and efficiency and even the combination of all three. Some ideas remained intact as the materials required to conduct the experiment was very costly and were also not abundant. As the basic idea was to commercialize it, there...
