Preparation and Evaluation of Polypropylene-Peanut Shell Flour Eco-Friendly Composites with and without Cloisite 30B
Authors : Haydar U. Zaman,Ruhul A. Khan,


Polymer composites strengthened with natural fibers are much attractive than traditional component due to their availability, renewability, low weight and cost, low density, and biodegradability. There are a variety of natural fibers, such as coir, hemp, jute, and palm that can be applied as reinforcement or filler, showing potential as a replacement for inorganic fibers. Plastics are frequently...

Effect of Sintering condition on Magnetization and Microstructure of CuxCo(1-x)Fe2O4 Ferrites
Authors : K.P. Mudholakar,S. Vinaykumar,VinutV. Tambe,S.V. Angadi,S.S. Kakati,Shridhar N. Mathad,Sachin S. Tirlapur,I.B Madalagi,Deepak B. Shirgaonkar,A.S. Pujar,S.L. Galagali,P.R. Jeergal,S.S. Khemalapure,C.S. Hiremath,R.B. Pujar,


Nowadays, ceramic magnets are produced artificially under precisely managed sintering and compositional circumstances. As a result, copper doped cobalt ferrites with the general chemical formula CuxCo(1-x)Fe2O4 (x=0.0, 0.4, and 1.0) were made using the standard ceramic method under varied sintering conditions using AR grade oxides. The formation of a single-phase spinel structure is demonstrated...

 Influence of Fiber Surface Modifications on Fiber-Matrix Interaction in Plant and Waste Fiber Reinforced Thermoplastic Composites
Authors : Haydar U. Zaman,Ruhul A. Khan,


In the last century, polymers have appeared as one of the best essential materials used in daily life, polypropylene (PP) being one such instance. Until lately, synthetic filler ingredients were the desired choice for improving the strength of PP. Nevertheless, natural filler/fiber ingredients are developing as appropriate substitutes to synthetic ingredients for strengthening polymers such as...

Transient stability Studies of series FACT Device: A Comparative Study of GCSC and TSSC
Authors : M. Santhosh Raikar,G.D. Kamalapur,


Today's power system continues to expand exponentially due to extensive automated need for both domestic and industrial needs. The expansion of power transmission networks is limited due to environmental right of way and economic reasons. The ever growing demand of power system network has resulted in rotor angle oscillations and voltage instability. It is precisely due to the inability to...

Optimization of Voltage-Controlled Oscillator based on Heterostructure to increase the density of their elements. Influence of Mismatch-Induced Stress and Porosity of Materials on Technological Process Development
Authors : E.L. Pankratov,


In this paper we introduced an approach to increase integration rate of field-effect heterotransistors in the framework of a voltage controlled oscillator. We formulate recommendations for optimization of annealing to decrease dimensions of field-effect heterotransistors and to increase their density. At the same time one can decrease transition area between doped and undoped areas of elements...

Development and Experimental Performance Evaluation of a Multifunctional Refrigerator for Food Preservation
Authors : G.N. Nwaji,C.I. Obiokpara,C. Nwabude,O.F. Ovadje,E.E. Anyanwu,


A multifunctional refrigerator for heating and cooling of food has been designed, tested and presented in this work. It is a more viable alternative means of keeping food warmth before consumption rather than using the conventional microwave oven. The waste energy from the refrigerator is harnessed and routed to a heating chamber where it is used to heat up processed food materials. The system...

Extraction and Characterization of Nanocrystalline Cellulose from Agricultural Residue-Oil Palm Petiole Fiber
Authors : O.U. Nwosu,S.C. Nwanonenyi ,C.O. Osuagwu,N. Nnawugwu,U.G Eziefula,C. Ononogbo,


The aim was to investigate the use of oil palm petiole fiber (OPPF) as a source for producing nanocrystalline cellulose. OPPF was treated with alkali (NaOH) first, and bleached before the production of nanocellulose by acid hydrolysis (H2SO4). The materials obtained after each stage of treatments were characterized and their chemical compositions were determined. The produced materials were...
