Carbon monoxide oxidation on bimetallic Ru/Au(111) surfaces [PDF]

Journal of the Serbian Chemical Society, 2001
The electrochemical deposition of Ru on Au(111) was performed in 0.5 M H2SO4 + 10-4 M RuCl3. The obtained bimetallic Ru/Au(111) surfaces were characterised by cyclic voltammetry and in situ STM in 0.5MH2SO4.

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.

Formation of surface states on Pb(111) by Au adsorption

Scientific Reports, 2023
Using low-energy electron diffraction and angle-resolved photoemission spectroscopy, we investigated the lattice and electronic structures of the Pb(111) surface upon the adsorption of Au atoms at the low temperature T = 40 K.

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 ...

Carbon monoxide oxidation on a Au(111) surface modified by spontaneously deposited Ru [PDF]

Journal of the Serbian Chemical Society, 2001
The spontaneous deposition of Ru on Au(111) was performed in 10-3MRuCl3 + 0.5MH2SO4 solution. The obtained surface was characterized by STM under potential control in 0.5MH2SO4 solution.

Preclinical Characterization of a Stabilized Gastrin-Releasing Peptide Receptor Antagonist for Targeted Cancer Theranostics

Biomolecules, 2023
Radiolabeled gastrin-releasing peptide receptor (GRPR) antagonists have shown great promise for the theranostics of prostate cancer; however, their suboptimal metabolic stability leaves room for improvements. It was recently shown that the replacement of

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.

Structure determination of Au on Pt(111) surface:LEED, STM and DFT Study [PDF]

, 2015
Low-energy electron diffraction (LEED), scanning tunneling microscopy (STM) and density functional theory (DFT) calculations have been used to investigate the atomic and electronic structure of gold deposited (between 0.8 and 1.0 monolayer) on the Pt(111)
