Synthesis and Structural Characterization of Cobalt Nanostructures in AAO Membranes

Abstract

Metallic nanostructures have attracted the interest of researchers due to their fundamental importance and potential applications in nanodevices, sensors and catalysts. Co-AAO nanocomposites were obtained by using a sol-gel method that uses ultrasonic vibrations to induce the penetration of a colloidal solution through the pores of an anodized aluminum oxide (AAO) template. The AAO template, with the sol into its pores, was annealed at 648 K. The entire dip-anneal-dip�process was repeated three times. Finally, the metal nanostructures were formed by further annealing at 873 K in hydrogen atmosphere for 1 h. The morphology and structure of Co-AAO were investigated by using SEM, HRTEM, XRD and EPR methods.

In Vitro Study Regarding the Biomechanical Behaviour of Bone, Fibre Reinforced Polymer and Wire Composite Perio-dontal Splints. Model Analysis

“…While the clinical rational for splinting is less disputable in current scientific literature [16][17][18][19][20][21], the latest advances in splinting materials and the wide variety available [22] can create confusion among practitioners. There is even less information regarding the biomechanical response of the periodontal complex in the context of different bone resorptions and splints [23][24][25][26][27][28][29][30][31][32][33]. These aspects make splinting therapy to be a challenging decision for dental professionals.…”
