  • Time will tell whether these findings are relevant to how dinitrogen is reduced to ammonia in nature on a huge scale by nitrogenase enzymes.

  • With support of the NIH I also was able to achieve in 2003 a long sought goal for hundreds of researchers over a period of 40 years, the catalytic reduction of dinitrogen with protons and electrons at room temperature and pressure.
