Análisis de la bioactividad de Mg AZ31 recubierta por PEO (Plasma Electrolytic Oxidation)

DYNA, 2018
El Magnesio es un material que presenta propiedades favorables para su selección como biomaterial; sin embargo, su aplicación se ve restringida por la rápida corrosión. En esta investigación se evaluó la modificación superficial de magnesio AZ31 mediante PEO y su efecto sobre las propiedades protectoras y bioactivas.

PFAS Removal by Anion‐Exchange Block Copolymer Membranes Featuring Highly Ordered Alternating Gyroid Nanochannels

Journal of Polymer Science, EarlyView.
Engineering positively charged alternating gyroid nanochannels in block copolymer membranes provides a powerful tool for efficient PFAS removal. ABSTRACT Ion‐exchange resins (IERs) can effectively remove per‐ and polyfluorinated alkyl substances (PFAS) from water through electrostatic interactions between the negatively charged PFAS and the positively ...

Engineered surface strategies to manage dental implant‐related infections

Periodontology 2000, EarlyView.
Abstract When exposed to the oral environment, dental implants, like natural surfaces, become substrates for microbial adhesion and accumulation, often leading to implant‐related infections—one of the main causes of implant failure. These failures impose significant costs on patients, clinicians, and healthcare systems.
