An easy method was used to modify the Cloisite Na+ with different cationic surfactants. To prevent the damages in the clay crystal structure, the process was taken without acid activation. The organo-modified montmorillonite (MMT) were characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), thermal analysis (TG/DTG), field emission scanning electron microscopy ...

Background: The commissioning accuracy of Volumetric Modulated Arc Therapy (VMAT) need to be evaluated.Objective: To test and evaluate commissioning accuracy of VMAT based on the TG 119 protocols at local institution. Material and Methods: The phantom, structure sets, VMAT and IMRT beam parameter setup, dose prescriptions and planning objectives were following TG 119 guidelines to c...

A new method for preparing 1,5-diphenylselenocarbazone (selenazone) nanoparticles and their complexes with Pb2+, Cd2+, Co2+, Ni2+ has been performed using hot methanol solvent. The ligand its were characterized FT-IR, UV-Vis, 1H-NMR, 13C-NMR, X-ray powder diffraction (XRD), EI-mass spectrometry, scanning electron microscopy (SEM), HG flame-atomic absorption spectrophotometer, thermal analysis (...

BACKGROUND Medicinal herbs are used for the treatment of different ailments since antiquity. Different parts of Anethum sowa L. is used in folk medicine as a carminative for the treatment of flatulence, colic and hiccups of infants and children, antioxidant, antimicrobial and antispasmodic agent. The aim of our present study is to evaluate the chemical composition of the essential oil, proximat...

In this study, it is aimed to produce composite hydroxyapatite (HA) gelatin microspheres (HA-Gel) intended for drug delivery applications. The polymer network within the HA particle-matrix can be facilitated as a carrier system. dissolution of in physiological medium allows release controlled manner and also develop cell-microsphere interactions. Gelatin functionalized bare granules were produc...
