SiliceneĀ is a two-dimensionalĀ allotropeĀ ofĀ silicon, with a hexagonal honeycomb structure similar to that ofĀ graphene
Contrary to graphene, silicene is not flat, but has a periodically buckled topology; the coupling between layers in silicene is much stronger than in multilayered graphene; and the oxidized form of silicene, 2D silica, has a very different chemical structure from graphene oxide. History Al
ReductionĀ of xylose by catalyticĀ hydrogenationĀ produces theĀ sugar substituteĀ xylitol
XyloseĀ (cf.Ā Ancient Greek:Ā Ī¾ĻĪ»ĪæĪ½,Ā xylon, “wood”) is a sugar first isolated from wood, and named for it. Xylose is classified as aĀ monosaccharideĀ of theĀ aldopentoseĀ type, which means that it contains fiveĀ carbonĀ atoms and includes anĀ aldehydeĀ functional group. It is deriv
