Investigations were carried out to evaluate the performance of two-stroke, single cylinder spark ignition (SI) engine with alcohol blended (80% gasoline, 10% ethanol and 10% methanol by volume) having copper coated combustion chamber (copper-(thickness, 300 μ) coated on piston crown, and inner side of cylinder head).…
Nano MnO2 powder was synthesized by low temperature solution combustion method using oxalyl dihydrazide (ODH) fuel. The final product was well characterized by Powder X-ray diffraction (PXRD), Fourier Transform Infrared Spectroscopy (FTIR) and Scanning electron microscopy (SEM) for crystallographic purity, phase forma…
Abstract — In the present study, fabrication and characterization of compound composite nanofibers of Polyvinyl Alcohol (PVA) with nano silver and Polyamide 6 (PA6) are demonstrated. Compound composite fibers with core-shell structure were made using co-axial electrospinning method. The shell was made up of nano silve…
Geotextiles made of natural fibres like jute have been found to be effective in improving geotechnical characteristics of soil and are being extensively used for various technical end-uses viz. rural road construction, protection of river banks, stabilization of embankments, erosion control, management of slopes, cons…
In this research, the effect of wood species and particle size on mechanical properties of wood plastic composites (WPC) made of Poplar (Populus alba) and Alder (Alnus glutinosa) sawdust and high density polyethylene (HDPE) were investigated. Wood plastic composite (WPC) were made with 30% HDPE in a batch process at 1…
In this paper, an attempt has been made to study thermoelastic response of an inverse thermoelastic problem of a hollow cylinder occupying the space ,
The effect of variation of FeCl 2 concentration on the properties of magnetic nanoparticles produced by Massart’s procedure was investigated. Samples with different FeCl 2 concentration of 0.1, 0.8, 1.0, 1.2 and 1.5 M were produced. In this technique, an aqueous mixture of ferrous and ferric chloride was co-precipitat…
This paper deals with the investigation of dielectric properties of microwave dielectric ceramics with the general formula Ba6-3xR8+2xTi18O54 where R=La and x=2/3. Dielectric materials meet the demand and specifications of current and future systems due to their capability to reduce the size of microwave components an…
A semi-organic nonlinear optical crystal of Potassi um Ammonium L-Tartrate (PAT) has been grown by slow evaporation solution growth technique. The crystal system and lattice parameters are determined from the single crystal X-ray diffractio n analysis. Fourier transform infrared (FTIR) studi es confirm the various fun…
Summary The incorporation of natural antioxidants into fi lms and edible coatings can modify their structure, improving their functionality and applicability in foods, such as in fresh-cut fruits. This paper reviews the more recent literature on the incorporation of antioxidants from several sources into fi lms and ed…
The present paper reports the synthesis of SnO-Al2O3 composites via the hydrothermal route. The as-synthesized materials are characterized by different techniques, such as X-ray diffraction, High resolution scanning electron microscopy and UV-Visible spectroscopy. The A.C.conductivity of the composites were determined…
gest the existence of multiple sp 3 bonded phosphorene and arsenene allotropes that are stable as free-standing monolayers. We have found that -P (black), -P (blue), -P and -P allotropes of phosphorus are similarly stable, but display a different electronic structure. The monolayer of grey arsenic has a very similar s…
Thin sandwich panel made of high strength, high stiffness face sheets and light weight core material was envisaged here to replace the sheet metals. That may be frequently subjected to low intensity foreign body impacts. In this paper sandwich panels made of GF face sheets are tested under 6J, 12J and 18J impact energ…
Для достижения обеспечения максимальной эффективности инвестирования в эксплуатацию транспортной сети необходимо как можно более точно оценить надежность и остаточный ресурс сооружений. Применяемые в настоящее время в Республике Беларусь критерии остаточного ресурса для транспортных сооружений не позволяют выполнить е…
Mn-doped TiO2 material has been synthesized by sol-gel citrate method. Nanostructured 1% Mn-doped TiO2 (Nano-tio2)-poly vinyl alcohol (PVA) film has been fabricated on gold substrate to immobilized Urease (Urs) via physiosorption method for urea biosensor. The nanobiocompo- site film have been characterized by X-Ray d…
In this paper FLC based Maximum Power Point Tracking (MPPT) is proposed to an Interleaved Boost Converter for a Standalone PV system. This topology used to raise the efficiency of the PV power conditioning system. It minimizes switching losses and overall efficiency is increased when compared with the conventional Boo…
Hydroxyapatite (HA) is the main mineral component of bone and dental tissues, its basic application is production of biocompatible materials for medicine. Poly-L-lactide (PL) and blends of PL and starch were chosen as polymeric matrices. Pores in the polymer films were formed by a crazing mechanism. Crazing is a trans…
Frequency Selective Surface (FSS) is any surface that acts like spatial filter for electromagnetic wave and often used in indoors environment such as energy saving glass. Attenuation of GMS, GPS and personal communication signal leads to poor communication inside the building using regular shape of energy saving glass…
Abstract— S udanese rural tanning is an inherited craft. The methods and the indigenous materials employed by the rural tanners have remained unchanged for a long time. This is due to poverty, illiteracy, poor communications and lack of access to modern scientific technologies of leather production. As a result, the…
High quality single crystal of the quaternary thallium chalcogenide Tl2GaInTe4 compound were grown by a modified Bridgman technique. The goal of this paper is to present experimental results of the switching effect and analyze qualitatively the influence of various factors such as temperature, light illumination and s…
