Adherence of Molecules to Silica Glass Surface: Experimental Results and Theoretical Calculations
(Elsevier, 2013-01)
The adherence of molecules to surfaces is used in a wide scope of technological applications. In this work we study the attachment of molecules onto porous silica glass surface obtained from a Vycor glass, after glassglass ...
SERS mapping in langmuir-blodgett films and single-molecule detection
(2013-05-01)
Plasmon-enhanced spectroscopic techniques have expanded single-molecule detection (SMD) and are revolutionizing areas such as bio-imaging and single-cell manipulation. Surface-enhanced (resonance) Raman scattering (SERS ...

Adherence of model molecules to silica surfaces: first principle calculations
(Elsevier, 2013-01)
The adherence of model molecules to crystal SiO2 surfaces is studied from first principle calculations at the DFT level. Adsorption energies are calculated which follow the experimental threads obtained elsewhere (Rivera ...
Surface-enhanced resonance Raman scattering: Single-molecule detection in a Langmuir-Blodgett monolayer

Modification of Silicon Surface with Redox Molecules Derived from Ferrocene
(2010)
This study presents a new method to bind active redox molecules derived of ferrocene to the surface of single crystal silicon. The procedure consists in the reaction of hydrogenated silicon with allyl bromide activated ...
Oxygen assisted H2O dissociation on the Pt{110}(1 × 2) surface from first principles
(Elsevier Science, 2014-04)
Water dissociation with and without oxygen coadsorption is investigated on the Pt{110}(1 × 2) surface at low coverage from first principles. Calculations indicate that desorption of the water molecule is likely to occur ...
Formation of self-assembled monolayer of curcuminoid molecules on gold surfaces
(Elsevier Science, 2017-01)
We investigated the formation of self-assembled monolayers of two thiophene curcuminoid molecules, 2-thphCCM (1) and 3-thphCCM (2), on polycrystalline gold substrates prepared by immersion of the surfaces in a solution of ...
Density functional theory study of nitrogen atoms and molecules interacting with Fe(1 1 1) surfaces
(Elsevier Science, 2016-09)
We present Density functional theory (DFT) calculations for the investigation of the structural relaxation of Fe(1 1 1), as well as for the study of the interaction of nitrogen atoms and molecules with this surface. We ...
Langmuir-Blodgett films of diazobenzene molecules
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2008)
Langmuir-Blodgett (LB) films from diazobenzene Sudan III have been investigated using surface potential measurements as a function of number of layers and deposition pressures, with the surface potential data being related ...
