Nanoindentation: An emerging technique for polymer surface mechanical characterization
(Budapest University of Technology and Economics, 2007-10)
Polymer surfaces are the phase boundaries that reside between the bulk polymer and the outer environments. For many applications they have to be modified using physical or chemical processes to achieve the desired functional ...
Comparison of standard DFT and Hubbard-DFT methods in structural and electronic properties of TiO 2 polymorphs and H-titanate ultrathin sheets for DSSC application
(Elsevier Science, 2018-01-15)
The structural and electronic properties of several TiO 2 polymorphs and hydrogen titanate surfaces are modeled and studied by density functional theory (DFT). By implementing the Hubbard parameter “U” in our calculations ...
Uncovering the relationship between the structure and acid-base properties for hyperbranched polyester-polyols self-assembled on carbon surfaces
(Elsevier Science SA, 2021-01)
The self-assembly of three different generations of hyperbranched polyester-polyol polymers, based on 2,2-bis(methylol)propionic acid units (H20, H30, and H40 Boltorn®), on carbon electrodes was studied. The physico-chemical ...
Immobilization of alkyl-pterin photosensitizer on silicon surfaces through in situ SN2 reaction as suitable approach for photodynamic inactivation of Staphylococcus aureus
(Elsevier Science, 2021-02)
The tuning of surface properties through functionalization is an important field of research with a broad spectrum of applications. Self-assembled monolayers (SAMs) allow the surface tailoring through the adsorption of ...
Surface and interface properties of benzethonium chloride-montmorillonite
(Elsevier Science, 2017-05)
In this work, Montmorillonite (Mt) obtained from Tokat, Reşadiye region having 0.91 mmol/g cation exchange capacity was modified by using Benzethonium Chloride (BZT). Organoclays, from Mt and BTZ, were prepared by using ...
Surface properties of sediments from two Argentinean reservoirs and the rate of phosphate release
(Pergamon-Elsevier Science Ltd, 2006-12)
This article reports the surface properties (electrophoretic mobility, surface charge and specific surface area (SSA)), and phosphate release rates of sediments from two Argentinean reservoirs. Even though sediments are a ...
Development of micropatterning polyimide films for enhanced antifouling and antibacterial properties
(Elsevier Science, 2020-04)
A commercial biomedical Polyimide (PI) film was topographically and chemically modified by generating micrometric periodic arrays of lines using Direct Laser Interference Patterning (DLIP) in order to improve antifouling ...
Synthesis and surface-active properties of novel cleavable gemini surfactants
(Springer Heidelberg, 2021-09)
A novel series of quaternary ammonium gemini compounds having a butynylene spacer and different hydrocarbon chain lengths (CGBu8-16) were prepared. Carbonate group inserted between the hydrocarbon chains and the polar heads ...
The water/graphitic-carbon interaction energy
(Elsevier Science, 2007-03-30)
The water/graphitic-carbon interaction energy was obtained for a sample having a water surface site adsorption density of 13.3 μmol m -2 . The interaction energy was determined from the spreading pressure of water, its ...
Effect of annealing conditions on the optical properties and surface morphologies of (201)-oriented β-Ga2O3 crystals
(Elsevier Science, 2021-10)
The bulk properties of β-Ga2O3 are sensitive to temperature and atmosphere; therefore, suitable annealing conditions are required. This study was performed to investigate the effects of annealing conditions on the (201) ...
