Ru–based electrocatalyst It is well known that Ru is a superior catalyst in the traditional Haber−Bosch process 82 It has been theoretically proved that in both associative and dissociative mechanisms, the nitrogen adsorption energy and overpotential of Ru are much lower than those of other noble metals, such as Pd and Pt50, 83 It has also been experimentally demonstrated that Ru could .

Note: The name Monte Carlo simulation comes from the computer simulations performed during the 1930s and 1940s to estimate the probability that the chain reaction needed for an atom bomb to detonate would work successfully The physicists involved in this work were big fans of gambling, so they gave the simulations the code name Monte Carlo
Productivity improving technologies date back to antiquity, with rather slow progress until the late Middle Ag Important examples of early to medieval European technology include the water wheel, the horse collar, the spinning wheel, the three-field system (after 1500 the four-field system—see Crop rotation) and the blast furnace
