Sunulan çalışmada, Ni katkısının yaş kimyasal yöntemle hazırlanan Fe2O3’ün yapısal özellikleri üzerine etkileri X-ışını kırınımı (XRD), Fourier dönüşümlü kızılötesi (FTIR), diferansiyel termal analiz (DTA), termogravimetrik (TGA) ve taramalı elektron mikroskopisi (SEM) teknikleri kullanılarak araştırıldı. XRD FTIR sonuçları her bir numune için Fe2O3 yapının oluşumunu destekledi. 4at.%Ni katkısı...

In an attempt to enhance chitosan biological activities, biopolymeric Schiff bases of chitosan and different salicylaldehydes and their palladium(II) and platinum(II) complexes were synthesized and tested. The chemical structures of these derivatives were characterized using ¹H-NMR, FTIR spectroscopy and XPRD. Thermal analysis was done through TGA/DTG-DTA. Electronic absorption spectra and surf...

Here we report a newly synthesized vectorizing nanosystem, based on hydrodispersible magnetite nanoparticles (HMNPs) with an average size less than 10 nm, obtained by precipitation of Fe(II) and Fe(III) in basic solution of p-aminobenzoic acid (PABA), characterized by high-resolution transmission electron microscopy (HR-TEM), dynamic light scattering (DLS), X-ray diffraction (XRD), differential...

Cadmium oxide has found its applications in various areas of research such as solar cells, phototransistors, photodiodes, transparent electrodes and gas sensors. In the present work CdO nano particles were successfully synthesized from cadmium acetate through thermal decomposition at high temperatures by adopting the solid state reaction. The prepared nano particles are subjected to ball millin...

Poly-o-anisidine Sn(IV) arsenophosphate is a newly synthesized nanocomposite material and has been characterized on the basis of its chemical composition, ion exchange capacity, TGA-DTA, FTIR, X-RAY, SEM, and TEM studies. On the basis of distribution studies, the exchanger was found to be highly selective for lead that is an environmental pollutant. For the detection of lead in water a heteroge...

The urinary calculi formation is still now unknown problems and seems to be very complex phenomenon. The in vitro studies are carried out by artificial renal stone formation in silica gel medium. In general, it appeared that trace element (TE) contents in mixed structure are always between values of respective pure phases. It is also found that some of the toxic elements such as barium are rela...

Polyhydroxyalkanoates (PHA) are biodegradable and biocompatible green thermoplastics, synthesized by wide variety of bacteria as an intracellular carbon and energy storage intermediate. They are used as an alternative to nonrenewable petroleum derived plastics. The current interest in these biopolyesters is stimulated by the search for cost-effective capitalized production. This paper attempts ...

A complex of cerium(III) with 4-methyl-7-hydroxycoumarin was synthesized by mixing water solutions of cerium(III) nitrate and 4-methyl-7-hydroxycoumarin sodium salt in a metal-to-ligand molar ratio of 1:2. The complex was characterized and identified by elemental analysis, conductometry, IR, 1H and 13C NMR-spectroscopy, mass spectral data, DTA and TGA. Thermal analysis of the complex indicated ...

A hybrid nanocomposite composed of polyaniline-polystyrene-chitosan/zinc oxide was prepared via a simple in situ polymerization method. The synthesized copolymers were analyzed using Fourier Transform InfraRed (FT-IR), and UltraViolet-Visible (UV–Vis) spectroscopies, ThermoGravimetric Analysis (TGA), and Field Emission Scanning Electron Microscopy (FE-SEM), X-ray diffracti...

The organic nonlinear optical (NLO) material β-Alanine β-Alaninium Picrate (β-AAP) was grown by slow evaporation technique. Powder X-ray diffraction patterns were recorded and indexed for further confirmation of crystalline nature of grown (β-AAP) crystal. The transparent range of the grown material was studied using UV-Vis-NIR spectral analysis and the optical band gap was evaluated from the a...
