We present a transmission electron microscopy ~TEM!/Rutherford backscattering spectrometry ~RBS!/x-ray-diffraction ~XRD! study of Au evaporated on crystalline organic thin films of diindenoperylene ~DIP!. Cross-sectional TEM shows that the preparation conditions of the Au film ~evaporation rate and substrate temperature! strongly determine the interfacial morphology. In situ XRD during annealin...

The corrosion inhibition of mild steel in 0.5 M H2SO4 solution has been investigated using electrochemical methods, X-ray diffraction (XRD) and scanning electron microscope (SEM). The adsorption and inhibition action of acid corrosion of mild steel using cetyltrimethylammonium bromide (CTABr) and different halides (NaCl, NaBr and NaI) has shown synergetic effect. The results showed that the pro...

The one-step synthesis and characterization of nanostructured metallic platinum microspheres by a low-pressure flat flame technique is presented here. Field emission scanning electron microscopy (FESEM), X-ray diffraction (XRD) and X-ray Photoelectron Spectroscopy (XPS) analyzed the as-derived powders. Collectively, the results obtained from these analyses confirmed the formation of microsphere...

ZnS nanoparticles of different size have been synthesized using a colloidal particles method. ZnS nanoparticles prepared with capping agent (mercaptoethanol) then were characterized using X-ray diffraction (XRD) and UV-Vis spectroscopy. The particle size of the nanoparticles calculated from the XRD patterns has been found in the range 1.85-2.44nm. Absorption spectra have been obtained using UV-...

Silver nanoparticles were prepared by microwave irradiation of silver nitrate solution with carboxymethyl chitosan as reducing agent and a stabilizer. The optical properties, morphology and structure were characterized using UV–Visible spectrophotometer, transmission electron microscope (TEM) and X-ray diffraction (XRD). Appearance of surface plasmon band at 413 nm indicated the formation of si...

Nano sized ZnS and MnS2 were synthesized through a simple wet chemical route. In this Synthesis metal sulfides were used as the starting material and allowed to react with the transition metal source at 60°C for 75 minutes. The products were characterized by X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM), Photoluminescence spectra (PL), Raman Spectra, Thermogravimetry analysis Diff...

The optimum conditions for the fabrication of zein/Ag composite nanoparticles from ethanol/H₂O cosolvents using electrospinning and the properties of the composite were investigated. The zein/Ag nanoparticles were characterized using field-emission scanning electron microscopy, transmission electron microscopy (TEM), X-ray diffraction (XRD), and thermogravimetric analysis. The antibacterial act...

The present research attempt consists in the development of mesoporous hydroxyapatite using inexpensive ingredients using cetyltrimethylammonium bromide (CTAB) as template through a chemical-based hydrothermal method. Wide angle X-ray diffraction (XRD) reveals the formation of pure single-phased hydroxyapatite particles. Fourier transform infrared absorption spectroscopy (FTIR) and electron dif...

Polar and nonpolar ZnO thin films were deposited on MgO (001) substrates under different deposition parameters using oxygen plasma-assisted molecular beam epitaxy (MBE). The orientations of ZnO thin films were investigated by in situ reflection high-energy electron diffraction and ex situ X-ray diffraction (XRD). The film roughness measured by atomic force microscopy evolved as a function of su...

X-ray diffraction has been a standard technique for investigating structural properties of materials. However, most common applications in the organic materials community have been restricted to either chemical identification or qualitative strain analysis. Moreover, its use for polymeric thin films has been challenging because of the low structure factor of carbon and the thin film nature of t...
