In the published manuscript, "Thermal Stability and Magnetic Properties of Polyvinylidene Fluoride/Magnetite Nanocomposites. Materials 2015, 8(7), 4553-4564" [1], we detected that in three places the explanations were slightly incorrect. We apologize for any inconvenience this may have caused. [...].

Superparamagnetic few-layer graphene nanocomposites (FLG- NCs) can be used for many technological applications, such as solar cells, batteries, touch panels and supercapacitors. In this work, we applied electrochemical exfoliation method as a simple, one step and economical technique to fabricate FLG- NCs. The fabricated Superparamagnetic FLG- NCs were characterized by X-ray diffraction (XRD), ...

Magnetic nanoparticles were obtained using an adjusted Massart method and were covered in a layer-by-layer technique with hydrogel-type biocompatible shells, from chitosan and hyaluronic acid. The synthesized nanocomposites were characterized using dynamic light scattering, transmission electron microscopy, and Fourier transformed infrared spectroscopy. Biocompatibility of magnetic nanostructur...

Experimental and theoretical studies of light coupling to various magnetic nanostructured media and nanocomposites are briefly reported. Enhancement of the magneto-optical response is shown to occur when the constitutive materials of photonic crystals are magnetic. Transmission and reflection types of 1D magnetophotonic crystals (MPCs) have been studied. New possibility to enhance the magneto-o...

Gastric cancer, a high-risk malignancy, is a genetic disease developing from a cooperation of multiple gene mutations and a multistep process. Gene therapy is a novel treatment method for treating gastric cancer. Here, we developed a novel Arg-Gly-Asp (RGD) peptides conjugated copolymers nanoparticles-based gene delivery system in order to actively targeting inhibit the growth of gastric cancer...

In this research the synthesis of [Co(Salen)(PPh3)(H2O)]4[Fe(CN)6] and [Co(Salophen)(PPh3)(H2O)]4[Fe(CN)6] schiff base complexes was reported. Co3O4/CoFe2O4 magnetic nanoparticles were prepared by calcination of these complexes at 500, 550 and 600°C. Precursor complexes were identified by FT-IR and UV-Vis spectroscopy and their thermal behavior was studied via TG/DTA. Nanomagnetic samples were ...

In the present investigation, ZnFe2O4@MnO and MnFe2O4@ZnO magnetic nanocomposites were fabricated via a facile hydrothermal method and were calcined at 300 °C for 3 h. Synthesis of ZnFe2O4@MnO and MnFe2O4@ZnO magnetic nanocomposites optimized by the different weight percentages. The synthesized photocatalyst...

Alumina-based nanocomposites reinforced with niobium and/or carbon nanotubes (CNT) were fabricated by advanced powder processing techniques and consolidated by spark plasma sintering. Raman spectroscopy revealed that single-walled carbon nanotubes (SWCNT) begin to break down at sintering temperatures >1150 C. Nuclear magnetic resonance showed that, although thermodynamically unlikely, no Al4C3 ...

Gold nanoparticles (AuNPs) have attracted widespread attention for their excellent catalytic activity, as well as their unusual physical and chemical properties. The main challenges come from the agglomeration and time-consuming separation of gold nanoparticles, which have greatly baffled the development and application in liquid phase selective reduction. To solve these problems, we propose th...
