In addition, numerous methods have been explored, such as high-temperature migration 25, 26, pyrolysis 27, 28, atomic layer deposition 29, 30, wet chemical 31, 32, and physical deposition 33, 34 to synthesize SACs. It has become a booming field because of its considerable catalytic performance in various important industrial reactions, including the oxygen reduction reaction (ORR) 7– 9, oxygen evolution reaction (OER) 10– 12, hydrogen evolution reaction (HER) 13– 15, methane reforming 16– 18, methanol oxidation reaction (MOR) 19– 21, and ethanol oxidation reaction (EOR) 22– 24. Single-atom catalysts (SACs) have attracted enormous attention due to their intrinsic advantages, such as unique geometric and electronic properties and maximum atom utilization 1– 6. This work broadens the family of single-atom catalysts and opens a way to investigate highly efficient single-atom catalysts with multiple compositions. To prove utility, quinary high-entropy single-atom catalysts (FeCoNiCuMn) is investigated as oxygen reduction reaction catalyst with much more positive activity and durability than commercial Pt/C catalyst. Various high-entropy single-atom catalysts with tunable multicomponent are successfully synthesized with the same method by adjusting only the printing templates and carbonization parameters. Herein, we present a general route for anchoring up to eleven metals as highly dispersed single-atom centers on porous nitride-doped carbon supports with the developed movable type printing method, and label them as high-entropy single-atom catalysts. Without Gutenberg’s invention modern society may very well be hundreds of years less advanced than where we are currently.The controllable anchoring of multiple isolated metal atoms into a single support exhibits scientific and technological opportunities, while the synthesis of catalysts with multiple single metal atoms remains a challenge and has been rarely reported. In the modern world, the printing press laid the foundation for things like academic text books, online websites, and for others things as insignificant as a restaurant’s menu. The printing press helped to standardize they way we relay information through text, and helped bring books to the everyday member of society. Without the invention of movable type and the printing press during the Renaissance, we may be living in a completely different society today. The printing press had even spread across to the Americas by the mid-16th century. By the beginning of the 16th century, printing workshops had opened in many of the western European countries. The impact of Gutenberg’s invention soon spread across 15th century Europe. The invention of the printing press allowed books to be mass produced more quickly, allowing for the “flowering of knowledge” that occurred during the Renaissance. With the invention of the printing press and movable type, just about anyone could get their hands on a piece of literature. The invention of the printing press during the Renaissance had an enormous impact on not only the literacy rate, but also the amount of people who would now have access to books. The portrait at the top of the page is an artist’s depiction of what he believed Gutenberg to look like. Johann Gutenberg’s invention of the printing press and the affect had on the world during the time of the Renaissance, as well as the modern day impact it still has on us. Not long ago, the only available reading materials were in the form of physical texts, many of which were extremely costly to obtain due to being handwritten and hand-copied. In the day and age of modern technology, we often take for granted the fact that we can have long books and articles appear for us on a computer screen.
