Degradable magnesium implants: improving bioactive and antibacterial performance by designed hybrid coatings
(Materials Research Society, 2021-02)
Magnesium and its alloys are promising material candidates for degradable fracture fxation devices due to their suitable mechanical properties and biocompatibility; however, their fast corrosion in aqueous media causes ...
UV-photocurrent response of zinc oxide based devices: Application to ZnO/PEDOT:PSS hydrid Schottky diodes
(2021-01-01)
The UV photocurrent response of thin films of wide bandgap semiconductors such as zinc oxide (ZnO) can be applied to a great number of electronic devices aiming applications in environmental sensing or UV-detection. ...
Silver-functionalized methyl-silica hybrid materials as antibacterial coatings on surgical-grade stainless steel
(Elsevier Science Sa, 2016-03-25)
Development of new materials enriched with noble metal ions, such as silver, cobalt or copper, is of great interest in the field of commercial and medical products due to its action against fungus and bacteria. Although a ...
Role of Preparation Method on the Microstructure and Mechanical Properties of PPy/Ni Organic–Inorganic Hybrid Bilayer Coatings on Carbon Steel
(2015-07-29)
The efficacy of the conducting polymers as coating on a metallic substrate is strongly dependent on the manner how they are applied. Polypyrrole (PPy)/Ni organic–inorganic hybrid coatings were electropolymerized on commercial ...
A Comparative Study on Graphene Oxide and Carbon Nanotube Reinforcement of PMMA-Siloxane-Silica Anticorrosive Coatings
(2016-06-29)
Carbon nanotubes (CNTs) and graphene oxide (GO) have been used to reinforce PMMA-siloxane-silica nanocomposites considered to be promising candidates for environmentally compliant anticorrosive coatings. The organic-inorganic ...
Bioactive coatings deposited on titanium alloys
(Elsevier Science, 2006-09)
One of the ways to minimise corrosion products release from metallic implants to the surrounding tissue consists in applying a protective coating which may be functionalised with a bioactive material, able to generate a ...
Effect of the organic groups of difunctional silanes on the preparation of coated clays for olefin polymer modification
(Mineralogical Society, 2010-12)
Sodium montmorillonite (MMT) was organically modified with hexadecyltrimethylammonium ions and subsequently treated with dichlorosilanes and water, aimed at in situ silane condensation polymerization and modification of ...
Optical Fiber Relative Humidity Sensor Based on a FBG with a Di-Ureasil Coating
(Mdpi Ag, 2012-07-01)
In this work we proposed a relative humidity (RH) sensor based on a Bragg grating written in an optical fiber, associated with a coating of organo-silica hybrid material prepared by the sol-gel method. The organo-silica-based ...
