Scientists have now measured differential cross sections (DCSs) for the reaction H + D2 -> HD + D, which has enabled them to fill many of the gaps in our basic understanding of chemical reactivity.
Differential cross sections for H + D2 → HD(v′ = 2, j′ = 0,3,6,9) + D at center-of-mass collision energies of 1.25, 1.61, and 1.97 eV

Scientists have pinpointed the moment that the CO bond, the strongest bond of any diatomic molecule, breaks when oxidised by a gold catalyst.
Until now, research has only focussed on the catalysts’ active site and not on the reaction mechanisms. Graham Hutchings, Albert Carley and colleagues at the University of Cardiff have investigated the reaction mechanism occurring on a Au/Fe2O3 catalyst and found that CO dissociates at ambient temperature when co-adsorbed with O2.
‘The oxidation of CO gives a surprising result on a gold catalyst as the CO bond being broken is counter-intuitive since it is the strongest diatomic bond,’ says Hutchings.

The electronic transport properties based on the structures of an epoxy-pair chain on zigzag graphene nanoribbons are investigated.
I–V characteristics indicate that this graphene oxide can display the phenomenon of negative differential resistance (NDR) and may provide great potential applications in nanoelectronics by using modified graphene materials.
