The National Institute for Materials Science (NIMS)
and JEOL, Ltd. have developed a lanthanum hexaboride (LaB6)
nanowire-based field emission gun that is installable on an
aberration-corrected transmission electron microscope (TEM). This
combined unit is able to perform atomic resolution observation at
an energy resolution of 0.2 eV—the highest resolution ever recorded
for non-monochromatic electron guns—with a high current stability
of 0.4%.

    The New Fusion technology is based on a phenomenon called triplet-triplet annihilation (TTA) which is a process in which two triplet excitons annihilate and produce a higher energy singlet exciton.
