In this investigation kinetics and mechanism of NH3 synthesis over Fe(100) and K/Fe(100) model catalysts have been studied. In this context, adsorption kinetics of both N2/Fe (100) and H2/Fe (100)systems is initially investigated. By using statistical mechanic approach, we have determined the adsorption coefficient for N2 and H2 molecules as well as transition probability of different states ...
Prehistoric archaeologist and cultural anthropologist Marija Gimbutas was born exactly a century ago. Although she left us over quarter of ago (she passed away in 1994), her person still controversial ideas continue to attract considerable interest, reflected both by the acclaim harsh critique that work theories have received receive. In light recent archaeogenetic findings their interpretation...
