Moreover, gold ceases to benoble, and 2–3 nm nanoparticles are excellent catalysts which also exhibit considerable magnetism. At this size they are still metallic, but smaller ones turn into insulators. Their equilibrium structure changes to icosahedral symmetry, or they are even hollow or planar...

The rate-determining step in ammonia synthesis with iron catalysts is cleavage of the N≡N bond. Why is titanium inactive and iron active as a catalyst for ammonia synthesis? 在高温精巧分开的钛起反应与N2给稳定的氮化物。 率确定的步在氨综合与铁催化剂是N≡N债券的分裂。 为什么是钛不活泼和铁...
Gold nanoparticles can act as “catalysts” in chemical reactions. The surfaces of nanoparticles can also be harnessed to degrade pollutants, turn fuels into electricity in fuel cells, and tons of other great stuff! Their surfaces are also largely responsible for how these materials behave in the ...
and good electron mobility. The research on graphene has exponentially accelerated specially when Geim and Novoselov developed and analyzed graphene. On this basis, for industrial application, researchers are exploring different techniques to produce high-quality graphene. Therefore, reviewed in this article...
