A metal surface with chiral memory
Chem. Commun., 2014Prochiral molecules locally induce a chiral restructuring of the Cu(110) surface that persists after removal of the molecules.

Adsorption of Chiral Alcohols on “Chiral” Metal Surfaces
Langmuir, 1996Kink sites on high Miller index surfaces are either left- or right-handed and can be thought of as chiral, when the step lengths on either side of the kink site are unequal. A silver single crystal was oriented and cut to expose the Ag(643) surface on one side and the Ag(643) surface on the other side.

Step decoration of chiral metal surfaces
The Journal of Chemical Physics, 2009Highly stepped metal surfaces can define intrinsically chiral structures and these chiral surfaces can potentially be used to separate chiral molecules. The decoration of steps on these surfaces with additional metal atoms is one potential avenue for improving the enantiospecificity of these surfaces.

Surface Chirality of CuO Thin Films
Journal of the American Chemical Society, 2006We present X-ray photoelectron spectroscopy (XPS) and X-ray photoelectron diffraction (XPD) investigations of CuO thin films electrochemically deposited on an Au(001) single-crystal surface from a solution containing chiral tartaric acid (TA). The presence of enantiopure TA in the deposition process results in a homochiral CuO surface, as revealed by ...

Adsorption of Chiral Hydrocarbons on Chiral Platinum Surfaces
Langmuir, 1998Binding energies and configurations of chiral hydrocarbons adsorbed on stepped Pt surfaces are calculated using Monte Carlo simulations. McFadden et al. have recently shown that many stepped single-crystal surfaces have chiral characteristics and that chiral molecules adsorbed on these surfaces should display enantiospecific properties [McFadden, C. F.;

Chirality in adsorption on solid surfaces
Chemical Society Reviews, 2017Chemical chirality on solid surfaces has important implications in analytical separations, selective crystallizations and catalysis, and may help explain the origin of homochirality in life.

Chiral selection on inorganic crystalline surfaces
Nature Materials, 2003From synthetic drugs to biodegradable plastics to the origin of life, the chiral selection of molecules presents both daunting challenges and significant opportunities in materials science. Among the most promising, yet little explored, avenues for chiral molecular discrimination is adsorption on chiral crystalline surfaces - periodic environments that

Extended Surface Chirality for Enantiospecific Adsorption
Chemistry – A European Journal, 2008AbstractA rapid development of nanotechnology opens up a way for the fabrication of solid surfaces containing unique adsorption properties. In this article, we present the concept of a chiral nanostructured surface as a potential environment for the separation of chiral molecules. In particular, we focus on the effect of size and shape of the adsorbing

Enhanced sampling of chiral reactions on chiral surfaces
Understanding how chirality influences chemical reactivity at solid surfaces is central to the design of enantioselective catalysts and the development of asymmetric surface reactions. This thesis explores the adsorption and reactivity of chiral molecular precursors on chiral metal surfaces using a range of computational techniques, including density ...openaire +1 more source
