Mn2O3 nanoparticles have been synthesized using chemical co-precipitation method. The as were characterized by X-ray diffractometer (XRD), UV-Visible spectrophotometer (UV-Vis) and Fourier Transform Infra-Red (FTIR) results indicate that possessed crystallites having sizes 12.56 nm 11.90 with cubic orthorhombic structures respectively. two samples are named M1 M2. gas response of both the was i...

The development of biologically inspired silver nanoparticles (AgNPs) has attracted considerable worldwide attention in the field medical nanotechnology. This is because secondary metabolites possess unique reducibility required green synthesis nanoparticles. study for first time describes use an aqueous extract Lagenaria breviflora leaves (LBaq) AgNPs. methanolic (LBme) was analyzed to determi...

Long series of ozone profiles from 6 to 28 km at the Southern Tropics have been obtained from solar occultation measurements at twilight using a SAOZ spectrometer borne by long duration balloons. Two flights have been performed from Bauru in Brazil both in the summer, in February and March 2001 and 2003, from where the balloons 5 are moving westward at almost constant latitude (20 • ±5 • S). Th...

This research aims to study about developing and demonstrating the low-cost and portable light absorbance measurement device for using and learning in analytical experiments. In chemistry experiments, the concentration of solutions is important for mixing the sample or making medicines. In present, a UV-spectrophotometer is commonly used to check the absorbance of solution for investigating con...

in the past decade, magnetic nanomaterials have attracted much attention due to their physical properties and technological applications. in this work, α-fe2o3 nanoparticles were first synthesized via a simple co-precipitation method using iron chloride hexahydrate (fecl3.6h2o) as precursor and ammonia solution as precipitator. the samples were then characterized by high resolution transmission...

In this paper, CuO-ZnO nanocomposite was synthesized and its photocatalytic dye degradation ability from colored wastewater was studied. Basic Red 18 (BR18) and Basic Violet 16 (BV16) were used as model dyes. The characteristics of CuO-ZnO of were investigated using Fourier transform infrared (FT-IR) spectroscopy, scanning electron microscope (SEM) and X-ray diffraction (XRD). Photocatalytic dy...
