THE thermochemistry of difluoromethylene is of considerable interest in view of the apparent high stability of this radical. The largest (least negative) value for the heat of formation of ...

Scientists report that the metal ruthenium, supported with lanthanide oxyhydrides, can efficiently catalyze the synthesis of ammonia at a much lower temperature than the traditional approach. In their ...
