Surface modifications of Volcanic Glasses (Perlites) by water vapor
(Planta Piloto de Ingeniería Química, 2003-12)
Hydrothermal treatments on expanded volcanic glasses (perlites) were studied. The main objective of this paper is to obtain an activated surface able to interact with specific chemical substances. The above mentioned ...
Hydrophilic cloth by surface modification of polypropylene fabrics with mineral particles
(John Wiley & Sons Inc., 2022-05-07)
Different surface modifications of polypropylene non-woven fabric (NWF) by using mineral particles are proposed to increase fabric hydrophilicity. Particles from a zeolitized vitreous breccia are selected as an economic ...
How functionalized surfaces can inhibit bacterial adhesion and viability
(American Chemical Society, 2019-09)
Device-associated infections (DAI) remain a serious concern in modern healthcare. Bacterial attachment to a surface is the first step in biofilm formation, which is one of the main causes of DAIs. The development of materials ...
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 ...
Influence of subsurface oxidation on the structure, stability, and reactivity of grafted Si(111) surfaces
(American Chemical Society, 2008-09)
We investigated the influence of intermolecular interactions and subsurface oxidation on the structure, surface bonding, and reactivity of compact monolayers of small organic and inorganic molecules bound to the Si(111) ...
Development of an antifungal film by polyethylene surface modification with natamycin
(Elsevier Ltd, 2018-12)
An antifungal low-cost film for cheese packaging was developed using a tailor-made coating process by direct natamycin (Nat) spraying onto heat softened polyethylene film surface. Two spraying systems Nat/ethanol solution ...
Post-Synthetic Modification of ZIF-8 Crystals and Films through UV Light Photoirradiation: Impact on the Physicochemical Behavior of the MOF
(Wiley VCH Verlag, 2019-09)
The physicochemical modification of Metal-Organic Frameworks (MOFs) is a current challenge in the search to improve their performance in different technological applications. In this work we analyze the post-synthetic ...
Spray process to styrene grafting onto polyethylene film surface for paintability enhancement
(Elsevier, 2018-04)
A direct and fast post-processing method to modify polyethylene (PE) film surface is proposed in order to improve its paintability performance without changing its bulk properties. This goal is achieved by grafting styrene ...
Interactions of mimic weathered pyrite surfaces (FeS2) with acidic culture media (0 K): An approach for (bio)leaching applications
(Elsevier Science, 2018-12)
In biohydrometallurgical processes, a mineral exhibits different oxidation phases due to the system's heterogeneity, especially in heap leach pads. Oxidation chemically modifies the mineral surface altering its interface, ...
Spectroelectrochemical analysis of HOPG surface controlled modification
(Elsevier Science, 2017-04-14)
In situ Raman spectroscopy is used to characterize the changes induced by electrochemical oxidation and silver electrodeposition at the step-edge and terrace sites of highly-oriented pyrolytic graphite (HOPG) surfaces. Ag ...
