The Mixture of Nanoparticles of RuO2 and Pt Supported on Ti as an Efficient Catalyst for Direct Formic Acid Fuel Cell
(Springer, 2019)
An active coating, composed of a mixture of nanocrystals of RuO2 with the rutile structure and nanocrystals of metal Pt, was thermally synthetized on a titanium substrate. Cyclic voltammograms and polarization curves showed ...
In vitro evaluation of a multifunctional nano drug delivery system based on tigecycline-loaded calcium-phosphate/ poly-DL-lactide-co-glycolide
(Bio-Medical Materials and Engineering, 2014)
Most drug delivery systems as treatment modalities for osteomyelitis have not been evaluated for resistant infections. Tigecycline (TG) is an antimicrobial agent that could be used in the treatment of multi-drug-resistant ...
Synthesis of Cerium-Activated Yttrium Aluminate Based Fine Phosphors by an Aerosol Route
(Hoboken, NJ : John Wiley & Sons, 2012)
Polycrystalline fine powders of yttrium aluminate doped with Ce3+ were synthesised by spray pyrolysis of a polymeric precursor, which was obtained by dissolving the corresponding nitrates in a solution of ethylenediamine ...
Processing and characterization of UHMWPE composite fibres with alumina particles in poly(ethylene-vinyl acetate) matrix
(SAGE, 2018)
Processing of hybrid composites represents a challenge for engineers where the aim is to establish compatibility among several materials. The aim of this study is to evaluate the effects of different sizes and morphologies ...
45S5Bioglass®-based scaffolds coated with selenium nanoparticles or with poly(lactide-co-glycolide)/selenium particles: Processing, evaluation and antibacterial activity
(Colloids and Surfaces B: Biointerfaces, 2015)
n the bone tissue engineering field, there is a growing interest in the application of bioactive glass scaffolds (45S5Bioglass®) due to their bone bonding ability, osteoconductivity and osteoinductivity. However, such ...
Sintering Effects on Microstructure and Electrical Properties of CaCu3Ti4O12 Ceramics
(Hoboken, NJ : John Wiley & Sons, 2013)
CCTO powders were prepared by solid state reaction and mechanochemically, respectively. Synthesized powders were characterized by XRD, FE-SEM and PSA techniques. The sinterability of CCTO powders was investigated by heating ...
Nanoparticles of cobalt-substituted hydroxyapatite in regeneration of mandibular osteoporotic bones
(Journal of Materials Science: Materials in Medicine, 2013)
Indications exist that paramagnetic calcium phosphates may be able to promote regeneration of bone faster than their regular, diamagnetic counterparts. In this study, analyzed was the influence of paramagnetic cobalt-substituted ...
Synthesis of poly(ɛ-caprolactone) nanospheres in the presence of the protective agent poly(glutamic acid) and their cytotoxicity, genotoxicity and ability to induce oxidative stress in HepG2 cells
(Elsevier, 2014)
Nanospheres of poly (ɛ-caprolactone) (PCL) with sizes smaller than 200 nm were produced by combining the freeze drying method and the physicochemical solvent/non-solvent approach. The influence of various types of ...
Osteogenic and Antimicrobial Nanoparticulate Calcium Phosphate and Poly-(D, L-Lactide-co-Glycolide) Powders for the Treatment of Osteomyelitis
(Materials Science and Engineering: C, 2013)
Development of a material for simultaneous sustained and localized delivery of antibiotics and induction of spontaneous regeneration of hard tissues affected by osteomyelitis stands for an important clinical need. In this ...
Methoxy‐Substituted Hydroxychalcone Reduces Biofilm Production, Adhesion and Surface Motility of Acinetobacter baumannii by Inhibiting ompA Gene Expression
(Wiley, 2021)
An increasing lack of available therapeutic options against Acinetobacter baumannii urged researchers to seek alternative ways to fight this extremely resistant nosocomial pathogen. Targeting its virulence appears to be a ...
