The energy needed to change the magnetic orientation of a single atom – which determines its magnetic stability and therefore its usefulness in a variety of future device applications – can be modified by varying the atom’s electrical coupling to nearby metals.

Lithium and oxygen adsorption at MnO2 (110) surface

The adsorption and co-adsorption of lithium and oxygen at the surface of rutile-like manganese dioxide (β-MnO2), which are important in the context of Li–air batteries, are investigated using density functional theory. In the absence of lithium, the most stable surface of β-MnO2, the (110), adsorbs oxygen in the form of peroxo groups bridging between two manganese cations. Conversely, in the absence of excess oxygen, lithium atoms adsorb on the (110) surface at two different sites, which are both tri-coordinated to surface oxygen anions, and the adsorption always involves the transfer of one electron from the adatom to one of the five-coordinated manganese cations at the surface, creating (formally) Li+ and Mn3+ species. The co-adsorption of lithium and oxygen leads to the formation of a surface oxide, involving the dissociation of the O2 molecule, where the O adatoms saturate the coordination of surface Mn cations and also bind to the Li adatoms. This process is energetically more favourable than the formation of gas-phase lithium peroxide (Li2O2) monomers, but less favourable than the formation of Li2O2 bulk. These results suggest that the presence of β-MnO2 in the cathode of a non-aqueous Li–O2 battery lowers the energy for the initial reduction of oxygen during cell discharge.

The DNA nanopore (in blue) is a tube formed of folded strands of DNA. The porphyrin anchors, in red, anchor it securely between the two layers of the cell membrane (in grey), which is shown in cross-section.

Au- and Pt-Nanoparticle-Functionalized Tungsten Oxide Nanoneedles for Selective Gas Microsensor Arrays

C.Blackman, Adv. Funct. Mater., 2013, 23, 1313-1322; DOI: 10.1002/adfm.201201871

Chris Blackman demonstrates a new gas-phase method for the one-step synthesis of metal nanoparticles supported on nanostructured metal oxides as a featured cover article in Advanced Functional Materials. With no requirement for substrate pre-treatment, this provides for direct integration of the co-deposited nanomaterial with device structures and it is utilized for the fabrication of selective gas microsensor arrays based on gold and platinum decorated tungsten oxide nanorods.

John William Draper – When the College opened in 1828, the Professor of Chemistry who was appointed was Edward Turner. One of his students was John William Draper who later emigrated to the United States and became professor of chemistry at New York University. He had a distinguished career, particularly in the new field of photography. He was the first to photograph the moon (1840) and the Great Orion Galaxy (1880), and he is known as the first astrophotographer.
