چکیده

Spinel type nano ferrite compound MgFe2O4 was synthesized through sol gel technique using metal nitrates as precursors. The phase composition, morphology and elemental analysis of magnesium (MgFe2O4) were performed by X-ray diffraction, fourier transform infrared, atomic force microscopy, energy dispersive x-ray scanning electron analyses. 
 sample's diffraction pattern verifies the existence single material, with size its crystallites estimated to be 39.9 nm. Fourier infrared examination supported metal-oxygen vibrations corresponding tetrahedral octahedral sites, respectively. From microscopy image, grain obtained about 97.7 Raman spectra sample shows five active modes (A1g + Eg 3F2g), which is compatible spinel structure. Magnetic measurement study at room temperature a hysteresis loop behaviour low saturation magnetization value, 27.192 emu g-1 small coercivity value. optical band gap determined UV-visible transmittance spectra. Additionally, photoelectron spectroscopy are used confirm oxidation states explore chemical composition sample.

1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...

Spectroscopic and morphological studies of human retinal lipofuscin granules.

The emission properties of ocular lipofuscin granules isolated from human retinal pigment epithelial cells are examined by using steady-state fluorescence spectroscopy and spectrally resolved confocal microscopy. The shape of the emission spectrum of a thick sample of lipofuscin granules dried on glass varies with excitation energy. The polarization of this emission is wavelength-dependent, exh...

Preparation and characterization of CaF2:Ce3+ nanoparticles with spectroscopic studies

In this research Calcium fluoride nanoparticles and its different amount of cerium ion dopant (5%and 10%) were prepared. The mentioned nanoparticle were studied by fourier transform infrared spectroscopy (FTIR) , X-ray diffraction (XRD), absorption and photoluminescence spectra (PL) and Scanning electron microscopy (SEM). The XRD patterns indicate a typical cubic fluorite structure and no other...
