NANO SILVER WATER Nanotechnology is a rapidly growing science of producing and utilizing nano-sized particles that measure in nanometers (1nm = 1 billionth of a meter). One nanomaterial that is having an early impact in healthcare product is nano-silver. Nano silver water is almost pure atomic sized particle and de-ionized water with silver in suspension. Approximately 80% of the silver is in the form of metallic silver nano-particles and the remaining silver is in ionic form. The size of silver

3. RESULTS AND DISCUSSION The CoCaOxM crystals were grown by single diffusion gel growth technique and the harvested crystals are analysed by FTIR, XRD, SEM-EDX, UV-Visible and incubation studied. 3.1 Fourier Transform Infrared Spectroscopy The FTIR spectrum of CoCaOxM crystals were as shown in Fig 3. In FTIR spectrum, a strong band at 3434cm-1 and 3062cm-1 is due to asymmetric and symmetric OH stretching while an intense absorptions band at 3261cm-1 show inters molecular hydrogen bonded OH

Preparation and Characterization of Electrospinning Fluorine-doped Tin Oxide for Solar Applications. Shaker Ebrahim, Marwa Adel a, Moataz Soliman Department of Materials Science, Institute of Graduate Studies and Research, Alexandria University, P.O Box 832, Egypt a Department of Physics, Faculty of Science, Alexandria University, Egypt Abstract Transparent conductive films of fluorine doped tin oxide (FTO) electrospun on glass substrate were prepared. These transparent conductive films were prepared

After completion of the transesterification reaction employed at the optimal conditions, the catalyst was collected from the reactant mixture by filtration; the catalyst was washed with hexane several times to remove the adhered oil particles, and then dried at 110°C for 2 hr. The catalyst was reused several times without further treatment to obtain FAME from WCSO. To evaluate catalyst stability, the optimum amount of CaO that was obtained by examining the operating condition was stirred with 38ml

2. Optical properties of thick
metal nanohole arrays fabricated
by electron-beam and nanosphere lithography. INTRODUCTION Extraordinary optical transmission (EOT) through nanohole arrays has been concentrated broadly in several aspects, including the hypothesis and confirmation of its origin parameters influencing its intensity, the optical properties, for example like its transmission spectra and divergence. Several parameters including the refractive index of the medium on the metal film surface

nanoparticle was provided by Mie et al. [10,11]. Since the initial development of Mie theory, it is now well known that the strong optical properties of plasmonic nanoparticles result from an induced coherent oscillation of the free conduction-band electrons within the plasmonic nanoparticle. Thus, in our previous studies [12,13], bimetallic Au/Ag nanoframes with excellent LSPR feature were prepared via the galvanic replacement reaction and sulfidation and successfully used as the spectator for Co2+

1. SCANNING ELECTRON MICROSCOPY Scanning electron microscopy uses a focused beam of electrons to develop an image of the surface. Signal is generated by the interaction of electrons with the surface, which are then detected and perceived to obtain image and desired information related to the characteristics and topography. 1.1. WHY SEM USES ELECTRONS? The resolution power of an eye is about 0.2 mm. However, utilizing a microscope magnify this resolution power. The modern light microscope has a

INTRODUCTION Electron microscopes are generally microscopes that use electrons as a source of illumination to create an image, unlike light microscopes that relays on light. One of these types of microscopes is Scanning Electron Microscope (SEM), This microscope uses electrons to scan the surface of a sample giving an observer a highly magnified image of the sample. The electron microscope has been an amazing tool for research purposes around the world for many decades and the technique was discovered

analysis of material culture. During the development of archaeology, various different kinds of scientific techniques have been established to aid in archaeological investigation. Recent archaeological techniques and processes such as Scanning Electron Microscopy, Electron Spin Resonance (ESR) and Radiocarbon Dating are utilised to help better understand a civilisation, specifically the site of Lindow Man. These modern methods have supported in recognizing Lindow Man’s identity and important information
