Al2Mo3O12/polyethylene composites with reduced coefficient of thermal expansion
(Journal of Materials Science, 2014)
Recently, polymer composites reinforced with low fractions of thermomiotic nanoceramics have triggered a lot of research. The efforts have been focused on achieving considerable reduction of the coefficient of thermal ...
Development of lyophilized spherical particles of poly(epsilon-caprolactone) and examination of their morphology, cytocompatibility and influence on the formation of reactive oxygen species
(Paris : Association de pharmacie galenique industrielle, 2014)
A common limitation of using polymeric micro- and nanoparticles in long-term conservation is due to their poor physical and chemical stability. Freeze-drying is one of the most convenient methods that enable further ...
Investigating an organ-targeting platform based on hydroxyapatite nanoparticles using a novel in situ method of radioactive 125Iodine labeling
(Elsevier, 2014)
In this study, we have investigated the synthesis of nanoparticles of hydroxyapatite (HAp) and hydroxyapatite coated with chitosan (HAp/Ch) and the chitosan-poly-d,l-lactide-co-glycolide polymer blend (HAp/Ch-PLGA) as an ...
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 and morpho-structural characterization of nanostructured magnesium hydroxide obtained by a hydrothermal method
(Elsevier, 2014)
Controlled magnesium hydroxide particles were successfully synthesized via a simple hydrothermal method. The influence of temperature and reaction time on the hydrothermal synthesis of Mg(OH)(2) was studied. The results ...
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 ...
The influence of mechanical activation on the electrical properties of Ba0.77Sr0.23TiO3 ceramics
(Ceramics International, 2014)
Ferroelectric barium strontium titanate (Ba0.77Sr0.23TiO3), BST, was prepared by solid-state reactions using as the starting compounds powder of barium carbonate (BaCO3), strontium carbonate (SrCO3) and titanium dioxide ...
Hydroxyapatite nanopowders prepared in the presence of zirconium ions
(Elsevier, 2014)
Hydroxyapatite nanopowders were prepared in the presence of different concentrations of zirconium ions. Such crystallization conditions yielded significantly reduced particle size and increased specific surface area. Cell ...
Fluctuations of the number of adsorbed molecules due to adsorption–desorption processes coupled with mass transfer and surface diffusion in bio/chemical MEMS sensors
(Elsevier, 2014)
In this study we have developed, for the first time, the comprehensive theoretical model of the fluctuations of the number of adsorbed molecules in MEMS chemical and biological sensors, taking into account the processes ...
Structural study of monoclinic Li2FeSiO4 by X-ray diffraction and Mössbauer spectroscopy
(Journal of Power Sources, 2014)
A composite powder Li2FeSiO4/C is synthesized through a solid state reaction at 750 °C. The Rietveld crystal structure refinement is done in the monoclinic P21/n space group. It is found that the crystal structure is prone ...
