Due to the fact of their ability bond with human’s hard tissue, bioglasses have gained interest in biomedical field certain purposes regarding usage replacement, healing or repair bones. In form thin films, they trigger an increase biocompatibility for inert supports after implantation, based on surface engineering ensure osteoinduction. For that, this research is focused obtaining coatings cerium-enriched bioglass generate bioactive and potential additional antimicrobial antioxidant...
In this work, composite fibers connected in three-dimensional porous scaffolds were fabricated by electrospinning, starting from polycaprolactone and inorganic powders synthesized the sol-gel method. The aim was to obtain materials dedicated field of bone regeneration, with controllable properties bioresorbability bioactivity. employed nanometric a glass-ceramic type, fact that constitutes premise potential attachment living tissue physiological environment. morphological characterization...
In this work, calcium magnesium silicate ceramics were processed through the sol-gel method in order to study crystalline and morphological properties of resulting materials correlation with compositional thermal parameters. Tetraethyl orthosilicate calcium/magnesium nitrates employed as sources cations, ratios specific diopside, akermanite merwinite; they further subjected gelation, calcination (600 °C) treatments at different temperatures (800, 1000 1300 °C). The intermediate final...
The current work proposes the development of composite membranes based on bacterial cellulose (BC) loaded with silver (Ag) and zinc oxide (ZnO) nanostructures by in situ impregnation. research involves production purification BC, followed its loading different types phases help precipitating solutions, turmeric extract (green synthesis) ammonia (classic route). Additionally, combination both antibacterial agents into a single BC matrix to valorise benefits each, proposing novel BC-Ag-ZnO...
The main objective of the tissue engineering field is to regenerate damaged parts body by developing biological substitutes that maintain, restore, or improve original function. In this context, using electrospinning technique, composite scaffolds based on polycaprolactone (PCL) and inorganic powders were successfully obtained, namely: zinc oxide (ZnO), titanium dioxide (TiO2) hydroxyapatite (HAp). novelty approach consists in production fibrous membranes a biodegradable polymer loaded with...
The magnetic properties of low filling factor Fe-nanoparticle monolayers separated by relatively thick Al2O3 layers were investigated in parallel and perpendicular external field. thin film nanocomposites prepared sequential pulsed laser deposition on (100) Si substrates, the contain single-domain, dispersive nanoparticles. When field is oriented to layers, composite exhibits superparamagnetism. However, field, superferromagnetic order sets in, as revealed increase moment, hysteresis...
The current work focuses on the development of mineral scaffolds with complex composition and controlled morphology by using a polymeric template in form nonwoven fibre webs fabricated through electrospinning. By cross-linking process, gelatine fibres stable aqueous solutions were achieved, these being further subjected to loading step two types phases: calcium phosphates deposited chemical reaction barium titanate nanoparticles as decoration previously achieved structures. Thus, hybrid...
Here we present a new approach to overcome the optical diffraction limit by using novel materials. In paper, report experimental results obtained high-resolution transmission electron microscopy (HRTEM) and absorption spectroscopy, for fluorescent photosensitive glass-ceramic containing rare-earth ions such as samarium (Sm). Using home built dynamic tester, with low power laser, recorded nanostructures having 5 nm line widths. structure, measurements reveal presence of silver nanocrystals...
