Journal ArticleDOI
Isolated Metal Atom Geometries as a Strategy for Selective Heterogeneous Hydrogenations
Georgios Kyriakou,Matthew B. Boucher,April D. Jewell,Emily A. Lewis,Timothy J. Lawton,Ashleigh E. Baber,Heather L. Tierney,Maria Flytzani-Stephanopoulos,E. Charles H. Sykes +8 more
TL;DR: Desorption measurements in combination with high-resolution scanning tunneling microscopy show that individual, isolated Pd atoms in a Cu surface substantially lower the energy barrier to both hydrogen uptake on and subsequent desorption from the Cu metal surface.
Journal ArticleDOI
Experimental demonstration of a single-molecule electric motor
Heather L. Tierney,Colin J. Murphy,April D. Jewell,Ashleigh E. Baber,Erin V. Iski,Harout Y. Khodaverdian,Allister F. McGuire,Nikolai Klebanov,E. Charles H. Sykes +8 more
TL;DR: It is reported that a butyl methyl sulphide molecule adsorbed on a copper surface can be operated as a single-molecule electric motor using Electrons from a scanning tunnelling microscope to drive the directional motion of the molecule in a two-terminal setup.
Journal ArticleDOI
Controlling a spillover pathway with the molecular cork effect
Matthew D. Marcinkowski,April D. Jewell,Michail Stamatakis,Matthew B. Boucher,Emily A. Lewis,Colin J. Murphy,Georgios Kyriakou,Georgios Kyriakou,E. Charles H. Sykes +8 more
TL;DR: It is reported herein that the hydrogen spillover pathway on a Pd/Cu alloy can be controlled by reversible adsorption of a spectator molecule, which is termed a 'molecular cork' effect.
Journal ArticleDOI
Influence of point-defect scattering on the lattice thermal conductivity of solid solution Co ( Sb 1 − x As x ) 3
TL;DR: In this paper, the authors investigated the transport properties of solid solutions of skutterudites based on the Co-Sb sublattice and showed that the lattice thermal conductivity decreases with the increasing content of As at all temperatures.
Journal ArticleDOI
Molecular-scale perspective of water-catalyzed methanol dehydrogenation to formaldehyde.
Matthew B. Boucher,Matthew D. Marcinkowski,Melissa L. Liriano,Colin J. Murphy,Emily A. Lewis,April D. Jewell,Michael F. G. Mattera,Georgios Kyriakou,Maria Flytzani-Stephanopoulos,E. Charles H. Sykes +9 more
TL;DR: It is shown by studying a well-defined metallic copper surface that water alone is capable of catalyzing the conversion of methanol to formaldehyde, revealing an unexpected role of water, which is typically considered a bystander in this key chemical transformation.
