The catalyst keeps its structural integrity and excellent performance for the selective hydrogenation of 1,3 butadiene after exposure to a reductive atmosphere at 200C for 24h. Compared to commercial Pt nanoparticle catalyst on Al2O3 and control samples, this system exhibits significantly enhanced stability and performance for n hexane hydro reforming at 550C for 48h, although agglomeration of Pt single atoms into clusters is observed after reaction. In CO oxidation, the Pt single atom identity was fully maintained after 60 cycles between 100 and 400C over a one month period..
Will never forget when he looked at me in his office and said: are young and healthy. You are in perfect condition. Heart rate went up by about 40 bpm.

As difficult as it is to believe, there were plans at the time to dam the Colorado River, flood the Grand Canyon and turn it into a gigantic reservoir. Wooden drift boaters took to the river, along with a documentary crew, to make a film that brought national attention to the proposed reservoir project. This river journey helped save the Grand Canyon for future generations.
