Xanthine Quartets on Au(111) [PDF]
Journal of the American Chemical Society, 2017 The quartet of xanthine (X), a purine base ubiquitously distributed in most human body tissues and fluids, has been for the first time fabricated and visualized, as the first alternative purine quartet besides the known guanine (G)-quartet. The X-quartet network is demonstrated to be the most stable phase on Au(111).

Highly Biaxially Strained Silicene on Au(111) [PDF]
The Journal of Physical Chemistry C, 2021 Many of graphene's remarkable properties arise from its linear dispersion of the electronic states, forming a Dirac cone at the K points of the Brillouin zone. Silicene, the 2D allotrope of silicon, is also predicted to show a similar electronic band structure, with the addition of a tunable bandgap, induced by spin-orbit coupling.

In-situ STM study of phosphate adsorption on Cu(111), Au(111) and Cu/Au(111) electrodes [PDF]
Surface Science, 2013 Abstract The interaction of Cu(111), Au(111) and Cu-covered Au(111) electrodes with a neutral phosphate buffer solution has been studied by means of cyclic voltammetry (CV) and in situ electrochemical scanning tunneling microscopy (EC-STM). Under low potential conditions, both the Cu(111) and the Au(111) surface appear apparently adsorbate free ...

Super‐Robust Xanthine–Sodium Complexes on Au(111) [PDF]
Angewandte Chemie, 2022 AbstractA widely accepted theory is that life originated from the hydrothermal environment in the primordial ocean. Nevertheless, the low desorption temperature from inorganic substrates and the fragileness of hydrogen‐bonded nucleobases do not support the required thermal stability in such an environment.

Borophene Synthesis on Au(111)
ACS Nano, 2019 Borophene (the first two-dimensional (2D) allotrope of boron) is emerging as a groundbreaking system for boron-based chemistry and, more broadly, the field of low-dimensional materials. Exploration of the phase space for growth is critical because borophene is a synthetic 2D material that does not have a bulk layered counterpart and thus cannot be ...

Cyclotrimerization of arylalkynes on Au(111)
Chem. Commun., 2014 Cyclotrimerization of arylalkynes on Au(111) proceeds readily at modest temperatures, and affords two-dimensional covalently bonded polyphenylene networks.

Ordering of Air-Oxidized Decanethiols on Au(111) [PDF]
The Journal of Physical Chemistry C, 2018 Self-assembled monolayers (SAMs) of alkanethiols on gold are a commonly used platform for nanotechnology owing to their ease of preparation and high surface coverage. Unfortunately, the goldâ sulfur bond is oxidized at ambient conditions which alters the stability and structure of the monolayer.

Pseudodoping of Metallic Two-Dimensional Materials by The Supporting Substrates [PDF]
, 2018 We demonstrate how hybridization between a two-dimensional material and its substrate can lead to an apparent heavy doping, using the example of monolayer TaS$_2$ grown on Au(111).

Adsorption of imidazole on Au(111) surface: Dispersion corrected density functional study [PDF]
, 2016 We use density functional theory in the generalized gradient approximation to study the adsorption of imidazole on the Au(111) surface and account for dispersion effect using Grimme's empirical dispersion correction technique.
