The role of water in the taste mechanism of small carbohydrates and artificial sweeteners was derived from physico-chemical methods and spectroscopic studies of their aqueous solutions. The effect of bitter substance (Nicotine), Inhibitor of bitterness like Sucrose, Maltitol, Aspartame, beta-Cyclodextrin, Na-Gluconate, K-Gluconate and Acesulfame-K or Nicotine-Inhibitors mixtures on water...

Recently, notwithstanding abundance of hydrogen sources and also industrial development of membrane separation process it can be said hydrogen membrane separation after its productions processes especially through renewable sources can be good to solve human problems especially in the environment issues. This article is a study of a symmetrical two-dimensional modeling with finite element method...

Hydroxyapatite (Ca10 (PO4)6 (OH)2 is the most suitable biocompatible material for bone and tooth replacement, the HAp powder was synthesized using biological waste of Mussel-shell as calcium source and using di-ammonium hydrogen phosphate (NH4)2HPO4 as phosphate source. The grained powder of mussel shell was dissolved in diluted Nitric acid (HNO3) and di-ammonium hydrogen phosphate was...

Recently, Predicting the membrane processes performance with the usage of experimental models let the users to optimize the processes operating conditions. In this research, Artificial Neural Network (ANN) model for Ultrafiltration processes were evaluated by using oil-water separation experimental data. The comparison between the results from the mentioned model and experimental data showed that...

Corrosion inhibition effects of Ocimum Sanctum extract on aluminium in HCl were studied by weight loss, Potentiodynamic polarization method and AC impedance . Spectral studies such as FT-IR, UV studies show functional groups present in Ocimum Sanctum. The worn surfaces of aluminum plates were observed using scanning electron microscope (SEM). The maximum inhibition efficiency of weight loss...

We investigated the focusing properties of a phase modulated radially polarized doughnut Gaussian beam by a high numerical aperture (NA) lens based on vector diffraction theory. We observed that our proposed system generates a sub wavelength focal spot of 0.42λ having large uniform focal depth of 5 λ. This kind of non diffracting focal segments is called as dark channel, which may have...

The present study considered the amount of water-alcohol separation within the process of pervaporation by use of polymer membranes with the help of Artificial Neural Network modeling. Pervaporation can be utilized for separation of many liquids (in this study, it was used for separation of ethanol and butanol from water). All the mentioned alcohols have purity problems due to azeotropics with...

Silver and Magnesium doped ZnO nanoparticles were synthesized via Sol-gel method followed by calcinations at 500, 600 and 700°C for 2h. The influences of calcinations temperature on the particle size, the structural and morphological studies were examined by X-ray diffraction (XRD), Scanning Electron Microscope (SEM). The Elemental analysis have been estimated by Energy Dispersive ...

The metal oxide Nano particles doped semiconductor films were prepared by sol-gel technique and Dip-coating method. The Copper oxide, nickel oxide and tin oxide nano particles doped with silicon films are prepared .The metal oxide nano particles doped semiconductor films were exposed to DC glow discharge plasma and its optical analysis Ultra Violet visible band gap study, Structural analysis X...

Dolomite samples were collected from four different locations of Salem, Tamil Nadu and the percentage of dolomite present in these samples were studied using Fourier Transform Infrared Spectroscopy (FT-IR). The thermal decomposition behavior of sample which has more percentage of dolomite has been studied by thermogravimetric (TG) and Differential Thermal Analysis (DTA). TG-DTA analyses provide...

Modeling of Pevaporation process for water-alcohol separation with polymer membrane was performed using COMSOL Multiphysics software. Modeling was performed for two parts of the membrane and feed channel. For the feed section of the semiconductor, there is a mass transfer and semiconductor transfer term, while only the mass transfer occurs in the membrane. The flux from the membrane was...

The increasing fossil fuel prices due to demand for electricity and increasing environmental changes have revitalized the idea to move towards the renewable energy sources. The solar photovoltaic module is one of the most sustainable and effective system. Solar Photovoltaic (PV) cells can absorb only 70-80% incident solar radiations however only small amount of this incident energy converted into...
