You will be given a definition of a task first, then some input of the task.
In this task, we ask you to elaborate the sentence without changing its general meaning. You can do so by explaining further the input sentence, using more precise wording, adding qualifiers and auxiliary information etc.

Professor Schrock 's work is continuing with metathesis as well as projects such as dinitrogen fixation and single molecule catalysts which make ammonia from dinitrogen , similar to nitrogenase enzymes in biology .
Output:
Schrock 's work is ongoing with goals of furthering the understanding of metathesis selectivity , developing new catalyst architectures , as well as projects outside of metathesis , such as elucidating the mechanism of dinitrogen fixation and developing single molecule catalysts which form ammonia from dinitrogen , mimicking the activity of nitrogenase enzymes in biology .
