Synthesis of efficient antibacterial agents has become extremely important due to the emergence antibiotic resistant bacteria. This is especially true for Pseudomonas aeruginosa , an opportunistic pathogen having ability rapidly develop resistance multiple classes antibiotics thus limiting efficacy approved clinical use. Aluminum (Al)-doped NiO nanoparticles are special interest their enhanced ...

A desktop scanner was colorimetrically characterized to average CIELAB error of less than unity for Kodak Ektachrome transparencies and Ektacolor paper, and Fuji Photo Film Fujichrome transparencies and Fujicolor paper. Independent verification on spectrally similar materials yielded average ∆E*ab error of less than 2.1. The technique first modeled the image formation of each medium using eithe...

In the present study, binary oxide (cadmium oxide [CdO])x (zinc oxide [ZnO])1-x nanoparticles (NPs) at different concentrations of precursor in calcination temperature were prepared using thermal treatment technique. Cadmium and zinc nitrates (source of cadmium and zinc) with polyvinylpyrrolidone (capping agent) have been used to prepare (CdO)x (ZnO)1-x NPs samples. The sample was characterized...

Introduction: Fe-sulfates with OH &/or H2O are found in martian meteorites [e.g. 1] & on the martian surface [e.g. 2]. These minerals may provide evidence for past surface environments & potential habitability, [e.g. 3]. Several studies have characterized Fe-sulfates using spectral features [e.g., 4-6]. However, unique identification of Fe-sulfates is hampered by the occurrence of mineral assem...

Cu and Ni ferrites as the semiconductor materials were synthesized by a microwave sol-gel auto-combustion method. Two cationic surfactants, sodium dodecyl sulfate (SDS) and cetyltrimethylammonium bromide (CTAB), were applied and the influence of surfactants on the properties of the Cu and Ni ferrite particles was studied. The samples were characterized by X-ray powder diffraction (XRD) pattern,...

This paper deals with the photocatalytic reactivity of anatase titania particles, modified by surface deposition Cu2+ and Zn2+ oxide/hydroxide nanoparticles which are detected EDS FX techniques. The objective preparation steps was chosen to avoid formation larges Cu Zn oxide could be identified XRD other Their activity for methanol oxidation in water studied Rhodamine-B added as photo-sensibili...

In this work, we focused on improvement of rutile-type TiO2 degradation efficiency by cobalt doping and decorating on carbon nanotubes walls (CNTs) (Co-TiO2/CNTs). We also synthesized pure TiO2, Co-TiO2 and TiO2/CNTs samples for control experiments. The textural and morphology features of the samples were characterized by a range of analyses including: XRD, FESEM/EDX. FTIR, TEM, UV-Vis DRS and ...

Many image formation processes are complex interactions of several sub-processes and the analysis of the resulting images requires often to separate the influence of these sub-processes. An example is the formation of a color image which depends on the illumination, the properties of the camera and the objects in the scene, the imaging geometry and many other factors. Color constancy algorithms...

Aniline and its derivate are critical environmental pollutants, thus, the introduction of an eco-friendly catalyst for removing them is important research future. The ZnO supported on ball-mill prepared clinoptilolite nanoparticles (CNPs) was via ion-exchange process followed by calcination process. amount loaded in ZnO-CNP (CZ) samples varied as 0.54, 0.63, 0.72, 0.86 meq/g Zn(II) concentratio...

The yellow seal stone from northern Laos is one possible substitute for the Tianhuang Stone, most famous Chinese stone, because of its similar to orange-yellow appearance and same main mineral composition. colour causation was studied. samples’ phase, micro-morphology chemical components were studied by Raman spectroscopy, scanning electron microscopy (SEM) with energy disperse spectroscopy (ED...
