Research ArticleOpen accessPhrase in the titleNucleation and Crystal Growth Rates of Struvite in DTM Type Crystallizer with a Jet-Pump of Descending Suspension Flow in a Mixing ChamberJoanna Koralewska, Krzysztof Piotrowski, Boguslawa Wierzbowska, Andrzej MatyniaThe kinetic data concerning reaction-crystallization of struvite from diluted water solutions of Mg2+, NH4+ and PO43- ions in a continuous DTM-type liquid jet-pump crystallizer with internal circulation of suspension are presented and discussed. The measurements were performed with the assumption of minimal value of unit power of a jet-pump’s feeding stream, providing thus a minimal level of internal circulation intensity. … …American Journal of Agricultural and Biological Sciences, Vol. 2, Issue 4 · 31 Dec 2007 · 7,957 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleRaman Spectroscopy of Protein Crystal Nucleation and GrowthPechkova Eugenia, Maksimov, Georgy et al.Using Raman spectroscopy and the lysozyme as model system, we investigate the differences in protein conformation before and after Langmuir-Blodgett nanotemplate-induced crystal nucleation and growth. It was found, that the main difference in lysozyme conformation is associated to the higher amount of S-S bonds in lysozyme of LB crystals, probably in C-end of protein, resulting in the higher stiffness of … …American Journal of Biochemistry and Biotechnology, Vol. 10, Issue 3 · 8 Dec 2014 · 8,275 accessesView PDFCite
Research ArticleOpen accessIn the keywordsGROWTH OF YB3+ DOPED LiNBO3 CRYSTALS USING LASER HEATED PEDESTAL GROWTH METHODBariza Boudour, Youcef Boumaiza, Amar BoudourThe growth of LN single crystals free from defects greatly doped with rare earth elements (RE3+) and having a high optical quality is still an unresolved problem. Always, crystals of the niobate lithium contain a deficiency in lithium causing the appearance of intrinsic defects and thus a doping is required for the homogeneity. Our work was aimed to study the … …American Journal of Applied Sciences, Vol. 11, Issue 5 · 17 Feb 2014 · 6,912 accessesView PDFCite
Research ArticleOpen accessIn the keywordsFacile Synthesis of AgCl Hollow Nanospheres for Enhanced Photocatalytic PropertiesJing Chen, Yuling Zhao, Xinhui Liu et al.AgCl hollow nanospheres have been synthesized successfully via a hard-template approach using silica nanospheres as hard template for the first time. The phase, size and morphology of the as-prepared AgCl were investigated by X-Ray Diffraction (XRD), Field-Emission Scanning Electron Microscopy (FESEM); which reveals that the cubic AgCl hollow nanospheres with a cell constant a = 5.549 Å are 220 nm … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 3 · 22 May 2015 · 7,350 accessesView PDFCite
Research ArticleOpen accessIn the keywordsSynthesis of Baso4 Nanoparticles by Precipitation Method Using Polycarboxylate as a ModifierMohamed El-Shahate Ismaiel Saraya, Inas Mostafa BakrProblem statement: Barium Sulfate (BaSO4) is suitable for many applications because of its whiteness, inertness and high specific gravity. Approach: Nanoparticles of barium sulphate (BaSO4) have been synthesized from barium nitrate by precipitation method in the presence of water soluble organic polycarboxylic polymer as a modifying agent. Transmission electron microscopy, Scanning electron microscopy, Fourier transform infrared spectroscopy and X-ray powder … …Current Research in Nanotechnology, Vol. 2, Issue 1 · 29 Jul 2011 · 15,705 accessesView PDFCite
Review ArticleOpen accessIn the abstractContinuous Flow Synthesis of Zeolite-A from Coal Fly Ash Utilizing Microwave Irradiation with Recycled Liquid StreamSalman Bukhari, Sohrab RohaniCoal Fly Ash (CFA) was converted to zeolite using continuous microwave reactors while minimizing the wastewater produced during the zeolitization process. At bench scale, a continuous flow tubular microwave reactor was used to explore the effect of microwave irradiation on the crystallinity of the product. The waste water was reused in consecutive runs and Inductively Coupled Plasma (ICP) analysis was … …American Journal of Environmental Sciences, Vol. 13, Issue 3 · 19 Jun 2017 · 7,237 accessesView PDFCite
Research ArticleOpen accessIn the abstractLarge Scale Synthesis of ZnO Nanostructures of Different Morphologies through Solvent-free Mechanochemical Synthesis and their Application in Photocatalytic Dye DegradationRaúl Sánchez Zeferino, Jesús Alberto Ramos Ramón, Ma. Eunice de Anda Reyes et al.Well crystalline, near-stoichiometric zinc oxide nanostructures of different morphologies are fabricated in large scale, utilizing a simple, cost effective mechanochemical synthesis in absence of solvent. Effects of ionic and nonionic surfactants along with the concentration of hydrolyzing agent on the evolution of nanostructure morphology have been studied. It has been observed that while a cationic surfactant such as Cetyltrimethylammonium Bromide … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 1 · 16 Jan 2016 · 8,932 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Inhibitory Substances on Microbiospora Isolated from Soil under Cultivation of Curcuma Longa L.A. P. Kamble, Prakash Thorat, S. W. KulkarniProblem statement: Soil Pollution is major problem because different types of pesticides are used to control plant pest. The residual component of pesticide diffuses into the soil. It is necessary to check whether actinomycetes degrade these components and control the soil pollution. Approach: In Ayurved system of medicine the rhizome portion of Curcuma longa L. was used as an anti-inflammatory … …OnLine Journal of Biological Sciences, Vol. 12, Issue 1 · 16 Mar 2012 · 7,819 accessesView PDFCite
Research ArticleOpen accessIn the abstractPhotocatalytic Activity and Antibacterial Behavior of Fe3+-Doped TiO2/SnO2 NanoparticlesLek Sikong, Budsabakorn Kongreong, Duangporn Kantachote, Weerawan SutthisripokProblem statement: Since bacteria mainly causes damage on fresh vegetables and fruits during transportation to market, anti-bacterial TiO2 photocatalyst was applied for their packaging films. However, it has been known that pure TiO2 exhibits low photocatalytic property due to rapid recombination of photo-activated electrons and holes. Doping with metal or metal oxide shows the improvement of photocatalytic activity and disinfection … …Energy Research Journal, Vol. 1, Issue 2 · 31 Oct 2010 · 15,233 accessesView PDFCite
