Uniformly dispersed iron oxide–cellulose ferromagnetic nanocomposites were successfully obtained by ultrasonication, as a clean and energy-saving method.
Nanosized spinel ferrites MFe 2 O 4 (M = Ni, Co, and Zn) have been prepared by sol‐gel autocombustion method using citric acid as a fuel agent. The materials are characterized X‐ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), transmission electron microscopy (TEM). applied for Congo‐Red (CR) dye adsorption batch technique. Different kinetic equilibrium models fitted nonlinear regression to analyze the data. In accordance with Langmuir isotherm, maximum capacity at 293...
The poor water solubility of natural antioxidants restricts their bioavailability and therapeutic use. We aimed to develop a new phytosome formulation with active compounds from extracts ginger (GINex) rosehips (ROSAex) designed increase bioavailability, antioxidant anti-inflammatory properties. phytosomes (PHYTOGINROSA-PGR) were prepared freeze-dried GINex, ROSAex phosphatidylcholine (PC) in different mass ratios using the thin-layer hydration method. PGR was characterized for structure,...
3D hybrid perovskites based upon small organic cations gave start to a new intensively growing class of semiconducting materials. Here we report on the elaboration quantum dots recently emerged perovskite (AzrH)PbBr3 (AzrH = aziridinium cation). By employing antisolvent precipitation technique and stabilization with cationic surfactant succeeded in obtaining that display tunable luminescence. This piece work shows perspective aziridinium-based materials for advanced photonic nanostructures.
Cerium oxide nanoparticles were prepared by a precipitation method using Ce(IV) sulphate as precursor dispersed in glycerol with varying synthesis parameters such temperature or precipitating agent. The structural and morphological characteristics of the obtained investigated X-ray diffraction, transmission electron microscopy, diffuse reflectance spectroscopy. crystallite size varied between 13 17 nm. presence Ce3+ Ce4+ was proved XPS data CeO2 samples conservation fluorite structure...
In recent years, phytofunctionalized AgNPs have attracted great interest due to their remarkable biological activities. the present study, were synthesized using Abies alba and Pinus sylvestris bark extracts. The chemical profile of these extracts was analyzed by LC-HRMS/MS. As a first step, synthesis parameters (pH, AgNO3 concentration, ratio extract AgNO3, temperature, reaction time) optimized. characterized ATR-FTIR spectroscopy, DLS, SEM, EDX, TEM. Their antioxidant, cytotoxic,...
Physical hydrogels were obtained by freezing/thawing of aqueous solutions 15% poly(vinyl alcohol) (PVA)/poly(vinylpyrrolidone) (PVP) mixtures with different ratios between the polymers.
Polylactic acid (PLA) films were coated by coaxial electrospinning with essential and vegetable oils (clove argan oils) encapsulated into chitosan, in order to combine the biodegradability mechanical properties of PLA substrates antimicrobial antioxidant chitosan⁻oil nanocoatings. It has been established that morphology electrospun nanocoatings mainly depend on average molecular weight (MW) chitosan. Oil beads, main chitosan nanofibers, obtained using high-MW (Chit-H). naoparticles resulted...
Silver nanoparticles synthesized using plant extracts as reducing and capping agents showed various biological activities. In the present study, colloidal silver nanoparticle solutions were produced from aqueous of Picea abies Pinus nigra bark. The phenolic profile bark was analyzed by liquid chromatography coupled to mass spectrometry. synthesis monitored UV-Vis spectroscopy measuring Surface Plasmon Resonance band. characterized attenuated total reflection Fourier transform infrared...
