Ligand-mediated formation of Cu/metal oxide hybrid nanocrystals with tunable number of interfaces

Raffaella Buonsanti, Seyedehbehnaz Varandili, Dragos-Constantin Stoian, Jan Vávra, James Richard Pankhurst

Combining domains of different chemical nature within the same hybrid material through the formation of heterojunctions provides the opportunity to exploit the properties of each individual component within the same nano-object; furthermore, new synergisti ...

Polymer Lamellae as Reaction Intermediates in the Formation of Copper Nanospheres as Evidenced by In Situ X-ray Studies

Raffaella Buonsanti, Dragos-Constantin Stoian, Valeria Mantella, James Richard Pankhurst, Chethana Janardhana Gadiyar, Michal Stanislaw Strach, Kilian Frank

The classical nucleation theory (CNT) is the most common theoretical framework used to explain particle formation. However, nucleation is a complex process with reaction pathways which are often not covered by the CNT. Herein, we study the formation mechan ...

Exploring the Chemical Reactivity of Gallium Liquid Metal Nanoparticles in Galvanic Replacement

Raffaella Buonsanti, Seyedehbehnaz Varandili, Dragos-Constantin Stoian, Laia Castilla Amorós, James Richard Pankhurst

Micron/nanosized particles of liquid metals possess intriguing properties and are gaining popularity for applications in various research fields. Nevertheless, the knowledge of their chemistry is still very limited compared to that of other classes of mate ...

On isothermality in some commonly used plug flow reactors for X-ray based investigations of catalysts

Dragos-Constantin Stoian, Mark Adrian Newton

We compare two reactor setups commonly used to make operando measurements of catalyst behavior using X-rays in terms of the degree to which they may be considered to yield radial and axial isothermality. We use axial and radial Cu K-edge XANES mapping of c ...
