  A quantum effect at ambient conditions is presented. A benzene dithiol (BDT)
molecule or a tetrahydrofuran (THF) molecule is used as a barrier molecule
bridging the gold electrodes from a Mechanically Controllable Break junction.
It has been known for a long time that the environment of a junction couples to
the conduction. With a microscopic layer of fluid it is actually possible to
influence this coupling. The electrode-molecule-electrode configuration is
lined with a microscopic layer of THF fluid, also known as the partially wet
phase. This is effectively decoupling the electrode-molecule-electrode system
from environmental modes outside of this system. The effects on coherence and
quantum interference are exceptional.
