Research ArticleOpen accessEvery word in the titleFlow Dynamic Behavior of Fish Oil/Silver Nitrate Solution in Mini-Channel, Effect of Alkane Addition on Flow Pattern and Interfacial TensionKirubanandan ShanmugamThe mini-fluidic contacting system is developed as process intensification platform as an attractive alternative for existing liquid-liquid extraction system for separation of Omega 3 PUFA from using Aqueous 50% Wt. Silver nitrate solution. To improve the performance of extraction in mini-fluidics, it is necessary to study the flow-dynamic behavior of fish oil silver nitrate system in the channel. Moreover, different … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 2 · 26 Feb 2016 · 7,956 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSynthesis of Nanoparticles of Mixed Oxides Containing Titanium Cerium Silver and Silicon: Phase TransformationAkkarat Wongkaew, Waree Jansome, Supachai Khemchan et al.Problem statement: Titanium dioxide is a well known material using with self-cleaning application. This is due to its properties after exposed to UV light: Superhydrophilicity and photocatalysis. The addition of other oxides could prolong these properties without continuing exposed to UV. However, titanium dioxide phase is essential. In order to obtain these properties, titanium dioxide needs to be in anatase … …Energy Research Journal, Vol. 1, Issue 2 · 31 Oct 2010 · 7,824 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSynthesis and Characterization of Silver/Polyvinilpirrolidone (Ag/PVP) Nanoparticles Using Gamma Irradiation TechniquesShawkat Salameh Gasaymeh, Shahidan Radiman, Lee Yook Heng et al.Problem statement: In this study, attempts had been made to synthesize silver (Ag)/Poly Vinylpyrolidone (PVP) nanoparticles by ionizing radiation and at the same time overcoming some of the disadvantages previously reported by other methods such as impurities, solvent toxicity, size and distribution control and difficulty in their preparation that limits their commercialization potential. Approach: The use of this alternative method … …American Journal of Applied Sciences, Vol. 7, Issue 7 · 31 Jul 2010 · 9,962 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleQuantum Mechanical Calculation of the Optical Absorption of Silver and Gold Nanoparticles by Density Functional TheoryElham Gharibshahi, Elias SaionProblem statement: Metal nanoparticles confine the motion of conduction electrons and exhibit a strong optical absorption of electromagnetic radiation in the UV-vis-NIR region. The absorption is classically derived from the collective oscillations of free electrons in a metallic nanostructure as a consequence of incident electromagnetic radiation polarizing the particle optically embedded in a dielectric matrix. These oscillations, known as the … …Physics International, Vol. 1, Issue 1 · 31 Mar 2010 · 16,181 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSingle Beam Z-Scan Measurements of Nonlinear Refraction and Nonlinear Absorption Coefficients in Silver Nano-FluidEsmaeil Shahriari, W. Mahmood Mat YunusProblem statement: The nonlinear refractive index and nonlinear absorption are two important optical phenomena which are extensively used in optical switching, optical limiting and labeling. Approach: In the present research we had measured nonlinearity of Ag nano-fluid prepared using γ-irradiation method. The measurement was carried out using a single beam z-scan technique. Under a CW laser beam excitation operated at … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 1 · 31 Mar 2010 · 9,635 accessesView PDFCite
Research ArticleOpen accessIn the keywordsToxicology of Nanomaterials on ZebrafishJimmy De León, María del C. Cotto, Francisco MárquezIncreases in the use and the progressive manufacture of new Engineered Nanomaterials (ENMs) lead to inquire about their impact on the environment. Due to the small size, high reactivity inside organisms and the unusual physicochemical properties of the ENMs, the predictions of toxicity are very complex. The zebrafish (Danio rerio) has been granted as a practical alternative to study the … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 2 · 29 May 2019 · 7,784 accessesView PDFCite
Research ArticleOpen accessIn the keywordsGENE IMPRINTING: ENGRAVING THE PATHOGENESIS OF HERIDETARY DISEASESSandeep Satapathy, Roshan Kumar Singh, Harikrishnan RajendranGene imprinting has conduited the scope of our understanding of phenotypic expression and its corelation with constituent genotype. It is an epigenetic process that involves DNA methylation and histone modulation to attain monoallelic gene expression without altering the genetic sequences. A distinctive model of non-mendelian genetics, imprinting extends the control over expression of traits and selection of the allele that … …American Journal of Immunology, Vol. 10, Issue 1 · 12 Feb 2014 · 7,682 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAtomic Absorption Spectrometric Determination of Certain Fluoroquinolones in Pharmaceutical Dosage Forms and in Biological FluidsH. Salem, W. Khater, L. FadaSimple, accurate, sensitive and selective methods are described for the quantitative determination of ten fluoroquinolones (amifloxacin, ciprofloxacin hydrochloride, difloxacin hydrochloride, enoxacin, enrofloxacin, lomefloxacin hydrochloride, levofloxacin, norfloxacin, ofloxacin and pefloxacin mesylate). The methods are based on precipitation of the ion associates formed from the reaction of the cited drugs with silver nitrate, copper acetate and ferric chloride. The formation and solubility … …American Journal of Pharmacology and Toxicology, Vol. 2, Issue 2 · 30 Jun 2007 · 7,419 accessesView PDFCite
Review ArticleOpen accessIn the keywordsAntimicrobial Dressing for Diabetic Foot Ulcer Colonized with MRSAParthasarathy Ravichandran, Sai Prasad ChittiWound healing in patients with diabetic foot ulcer differs among people. The wound healing process was influenced by factors like nature of the wound, tissue and an immunity of a person. Any measure taken to control bacterial colonies in wound plays a significant role in wound healing. However, recent emergence of Methicillin-resistant Staphylococcus Aureus (MRSA) associated with chronic wounds created … …OnLine Journal of Biological Sciences, Vol. 15, Issue 4 · 17 Nov 2015 · 7,560 accessesView PDFCite
