plastic solar cells used a derivative of fullerene (a sphere-like carbon molecule) as an acceptor, together with a semiconducting polymer such as P3HT – poly(3-hexylthiophene-2,5-diyl) as a donor. They have achieved ... , or as a coating from solution in a continuous process. The plastic device would be lightweight and flexible, and could be scaled ...

To avoid this problem, we have developed a special technique to control the positioning of each plate in the stack with a precision of greater than 0.1 degrees.” A prototype of the adaptable V-bender was ... designing a supermirror polariser for a cold neutron beam, you need to choose between optimum transmission and very high polarisation – with ...

Spurions is a commonly used expression for parasitic signals, which can be easily mistaken as real signals from the studied sample. There ...

capture.Whenever a nucleus captures a slow neutron, a compound nucleus is formed. The excitation energy is close to the binding energy. The compound nucleus decays by emitting gamma-rays in a cascade.

Thus only 1/3 of the sample volume ... very difficult on a classical TAS instrument, with the additional problem of the attribution of satellites to A or B. As demonstrated ...
