Nanoporous platinum thin films synthesized by electrochemical dealloying for nonenzymatic glucose detection
Amperometric response of nanoporous Pt films to glucose and other interfering species.
Local deposition of anisotropic nanoparticles using scanning electrochemical microscopy (SECM )
The local control of either Au nanoparticles (A) or nanorods (B) was accomplished by scanning electrochemical microscopy, which was used in a double pulse approach and in the presence of a surfactant, which assisted the anisotropic growth of Au seeds.
Modelling electrified interfaces in quantum chemistry: constant charge vs. constant potential
If electrochemical reactions are simulated using finite quantum chemical DFT approaches, the conventional picture is the “constant charge” scheme with a fixed number of electrons. An alternative is the “constant potential” ansatz, in which the Fermi level is fixed and the number of electrons is variable.
Methanol reactions on bimetallic Ru(0001)-based surfaces under UHV conditions
Thermally induced methanol reactions on bimetallic surfaces with particular attention devoted to the influence of coadsorbed oxygen.
Ruthenium sulphide thin layers as catalysts for the electrooxidation of water
For the first time crystalline RuS2 thin layers are prepared via reactive magnetron sputtering technique and are electrochemically characterized as an active catalyst for the oxygen evolution reaction.
Surface aspects of sol–gel derived hematite films for the photoelectrochemical oxidation of water
Hematite films were successfully modified in an oxygen plasma in order to form electrochemically active surfaces for the photo-induced oxygen evolution reaction.
Electrochemical-surface enhanced Raman spectroscopy (E-SERS) of uric acid : a potential rapid diagnostic method for early preeclampsia detection
Electrochemical SERS was used to rapidly detect uric acid in synthetic urine with the proof-of-concept goal towards development of a diagnostic test for early preeclampsia detection.
Mechanistic aspects of the linear stabilization of non-stationary electrochemical oscillations
The problem of non-stationarity in experimentally recorded time-series is common in many (electro)chemical systems.

Iron 3p resonant X-ray spectroscopy on anodized hematite photoanodes shows evolution of a hole doped film with increasing current density.
Spectroscopic assessment of the role of hydrogen in surface defects, in the electronic structure and transport properties of TiO2, ZnO and SnO2 nanoparticles
The role of the reducing conditions in the metal oxides stoichiometry, electronic structure and resulting lowering of the potential barrier for the charge transport is evidenced by complicity of the XPS, DRS and EIS.
Theory of the transition from sequential to concerted electrochemical proton –electron transfer
A systematic study of the transition from sequential to concerted electrochemical proton–electron transfer based on a suitably parameterized Hamiltonian.
The effect of Al-doping on ZnO nanoparticles applied as catalyst support
