A radical route from methane to methanol The conversion of into chemicals usually proceeds through high-temperature routes that first form more reactive carbon monoxide and hydrogen. Agarwal et al. report a low-temperature (50°C) in aqueous hydrogen peroxide (H 2 O ) for oxidizing high yield (92%). They used colloidal gold-palladium nanoparticles as catalyst. primary oxidant was ; isotopic labeling showed H activated methyl radicals, which subsequently incorporated . Science , this issue p. 223
Heat treating Fe/ZSM-5 under hydrogen leads to high dispersion of Fe species and higher alcohol selectivity in the oxidation alkanes, as compared oxygen treated catalysts.
PVP polymer stabilisers effect the reactivity of AuPd nanoparticles towards H<sub>2</sub>O<sub>2</sub> synthesis/decomposition and methane oxidation.
We used rheology and confocal microscopy techniques to characterise the flow of emulsions as droplets were confined by increasing drop volume fraction reducing distance between shearing surfaces. Slip was minimised matching density oil water phases. Attractive interactions drops caused them flocculate. The contribution emulsion microstructure its shear response becomes significant when flocs almost span found that confining droplet causes a transition from fluid phase with thinning behaviour...
