#China and India race to fully harness thorium for nuclear power Thorium is an alternative to uranium as a way of doing nuclear fission.
Thorium is an alternative to uranium as a way of doing nuclear fission he told Metro.
That phenomenon known as singlet exciton fission was identified first in the 1960s. However, achieving it in a functioning solar cell has proved difficult
Exciton fission has now been observed in a variety of materials all discovered like the original ones by chance. e can rationally design materials
and devices that take advantage of exciton fission until we understand the fundamental mechanism at work until we know what the electrons are actually doing,
The samples were made of four types of exciton fission molecules decorated with various sorts of pinachbulky side groups of atoms that change the molecular spacing without altering the physics or chemistry.
To detect fission rates which are measured in femtoseconds (10-15 seconds) the MIT team turned to experts including Moungi Bawendi, the Lester Wolfe Professor of Chemistry,
Van Voorhisnew first-principles formula successfully predicts the fission rate in materials with vastly different structures.
They show that molecular packing is important in defining the rate of fission but only to a point.
considers the new findings very important contribution to the singlet fission literature. Via a synergistic combination of modeling, crystal engineering,
and experiment, the authors have provided the first systematic study of parameters influencing fission rates, he says.
Their findings hould strongly influence design criteria of fission materials away from goals involving molecular packing
Nuclear fusion could produce far more energy far more cleanly than the fission reactions at the heart of today s nuclear power plants.
