Research ArticleOpen accessEvery word in the titlePreparation of LiCoMnO4 Assisted by Hydrothermal Approach and its Electrochemical PerformanceMeilin You, Xingkang Huang, Min Lin et al.LiCoMnO4 materials have been synthesized via a hydrothermal approach followed by a post-annealing process. Pure phase of LiCoMnO4 is unable to form under hydrothermal conditions; however, high quality of pure LiCoMnO4 was achieved after annealing the hydrothermal products. The concentration of LiOH and the post-annealing temperature are the crucial factors to form LiCoMnO4. Without post-annealing process, the highest contents of … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 2 · 23 May 2016 · 8,061 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePreparation of Magnetorheological Fluids Using Different Carriers and Detailed Study on Their PropertiesVikram G. Kamble, Shreedhar Kolekar, Chetan MadivalarHigh sensitive and intelligence are the main function of the Magneto Rheological Fluids (MRF). In this research work, magneto rheological samples are prepared with two different carrier oils (Honge and Castor) independently. Both the samples are mixed and prepared with same concentration of iron particles. In order to reduce the sedimentation fine lithium grease is added as stabilizer for both … …Current Research in Nanotechnology, Vol. 6, Issue 1 · 4 Sep 2015 · 13,120 accessesView PDFCite

It’s had smell gas produced by anaerobic digestion in acid condition from organic and inorganic compounds containing sulphur, presents dual problems of its toxicity and foul ordour. One of methods of its removal is adsorption. Activated carbon is a widely used … …American Journal of Environmental Sciences, Vol. 10, Issue 4 · 17 Jun 2014 · 8,480 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePreparation-Properties Relation of Mn-Cu Hopcalite CatalystArdita Mele, Ilo Mele, Altin MeleProblem statement: The Mn-Cu hopcalite catalyst was used for the conversion of CO to CO2 at low temperatures. It was the catalyst of choice in the gas masks for respiratory protection in mines, aircrafts, military, spatial laboratories. Approach: The efficiency of hopcalite catalyst depends on its surface parameters. Its surface characteristics can be influenced from the chosen way of the … …American Journal of Applied Sciences, Vol. 9, Issue 2 · 26 Dec 2011 · 7,888 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePreparation and Polishing Properties of Spherical Porous Silica AbrasiveHong Lei, Hu Li, Ping Liu, Ruling ChenProblem statement: Abrasive is one of key influencing factors on the polished surface quality in Chemical Mechanical Polishing (CMP). Solid abrasives in CMP slurries are easy to cause polishing scratches. It is well known that reducing the hardness of abrasives would improve the polished surface quality. Therefore, the change in structure or shape of the abrasives means a change in … …Current Research in Nanotechnology, Vol. 1, Issue 1 · 15 Jun 2011 · 9,285 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Polishing of Cutting-Edge Polymer-on-Glass for Pigtailing PreparationMohammad Syuhaimi Ab-Rahman, Fazlinda Ab-Aziz, Noor Azie Azura Mohd Arif et al.Problem statement: The high quality of cutting-edge surface is important in optical waveguide's efficiency. The perfect polishing of end surface is significant to deliver the best quality of light waves and minimize the device losses such as insertion loss and return loss. Hence, this research is concern on the parameters in polishing SU-8 polymer to increase the efficiency of waveguide. … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 1 · 31 Mar 2009 · 9,148 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAmphoteric Starch in Simultaneous Process Preparation with Box-Behnken Design for Optimal ConditionsSopa Cansee, Juntanee Uriyapongson, Commueng Watyotha et al.Cassava starch was chemically modified to produce an amphoteric starch. The amphoteric starch was prepared in a simultaneous process which was evaluated in relation to four factors: temperature (45-55 °C), 3-chloro-2-hydroxypropyltrimethylammonium chloride (CHPTAC, 4-12%) and sodium tripolyphosphate (STP, 2-8%) concentrations, and reaction time (2-6 h). The extent of amphoteric starch produced was determined by the degree of substitution (DS) of … …American Journal of Applied Sciences, Vol. 5, Issue 11 · 30 Nov 2008 · 7,523 accessesView PDFCite
