Since carbon nanotubes were discovered, till now no definitive formulation for computing the shear modulus of them was presented. To develop a theoretically rigorous and mathematically elegant expression for the shear modulus, thus, we initially propound a new small-strain theory in which merely small strain will aris…
Prototype fast breeder reactor’s (PFBR) secondary pumps have sealing between the rotating shaft and the stationary parts to prevent cover gas leakage into ambient air. This is achieved by means of triple mechanical seals with oil as buffer fluid. The oil for cooling the mechanical seals and bearing is supplied from an…
An attempt has been made in this research work to develop strong and tough bainitic steels in shorter transformation durations of less than three hours leading to ease of production for steel industries making these steels. High carbon medium alloy steel with high amounts of silicon, cobalt and aluminum was taken up f…
A three-dimensional microfluidic biosensor has been successfully designed using a low temperature co-fired ceramic (LTCC) technology. This microfluidic sensor consists of mixing, focusing and measuring region. The mixing region is a rectangular shaped channel, to enable the complete mixing of sample and buffered salin…
The main aim is to control thermal expansion in aluminium piston at high working condition. A plasma sprayed ceramic coating (TBC) is applied on the piston crown as a top coat and NiCrAl is applied as the middle layer as bond coat to improve the addition strength between the top coat and the metal subtract layer as Al…
PVC insulation has extensively been used for insulating low voltage electrical cables. They offer superior insulating properties but how ageing and exposure could affect their insulation properties is a matter of concern. Chemical exposure related failure modes are known but have received only limited study. The tradi…
The study of evaporation of water droplets over horizontal heated surfaces is an intense area of research because of its wide application in various fields of heat transfer. The characterization of the behavior of water droplets is important in studying the cooling effects produced over impinging surfaces. The present…
The material development is aimed at utilizing a suitable Metal Alloy in combination with a most appropriate plastic material considering the achievement of desirable basic features of Smart materials like Shape Memory Effect, Flexibility, recovery time etc. In the present work shape memory composites were developed u…
In recent year’s Natural Fibers reinforced composite (NFRC) are considered as a suitable alternative to engineering material due to their advantages like low cost, low density, high strength and stiffness to weight ratio, resistance to breakage during processing, low energy consumption, a lesser amount of pollutant em…
In the present work, an attempt has been made to explore the general microstructural characteristics and mechanical properties of titanium-titanium boride (Ti-TiB) composites (20 and 40 vol.% TiB reinforcement in Ti matrix) processed by Vacuum Sintering. The microstructures of the composites were investigated using el…
This paper presents comparison of magnetoelastic properties between the 〈110〉 oriented Tb x Dy 1-x Fe 1.95 polycrystalline alloys for x = 0.27, 0.3, 0.45 under coupled loading of magnetic field and compressive stress. The simultaneously measure are investigated for the magnetization and magnetostriction under applied…
In this work we have satisfied the objective to analyse the medium carbon steel rods which are welded frictionally on their tensile properties when the welding parameter is maximum and minimum in values of forging pressure with respect to time. This work also carries the macrostructure and microstructure analysis of t…
Diamond-like-carbon (DLC) coatings provide excellent surface properties on substrate. With novel advanced techniques like modeling and simulation, the performance of these coatings can be predicted under different loading condition. Aim of present study was to developed three dimensional models for calculating first p…
El propósito de este trabajo fue la identificación y la caracterización de los principales minerales en las fracciones arcilla de muestras de suelos tropicales que fueron seleccionadas de la Reserva Forestal de la Universidad Agraria de la Selva, localizada en la Región de Huánuco, Perú, con énfasis en el estudio de l…
合成了4种新型稀土三元固体配合物：REL2L’C1·nH20（RE：Nd^3＋、Eu^3＋、La^3＋、Sc^3＋；L=全反式维甲酸；L’=L-精氨酸阳离子），并对其进行红外光谱、紫外光谱、荧光光谱、元素分析和TG．DTA等测试。利用3-（4，5．二甲基噻唑．2）．2，5．二苯基四氮唑溴盐（MTT测试方法，初步探讨了配合物对体外培养的人肝癌细胞HepG2、人肺癌细胞A549和人宫颈癌细胞Hela生长的影响。结果表明：4种稀土配合物和稀土硝酸盐、配体全反式维甲酸和三．精氨酸盐酸盐对3种癌细胞株的生长都有一定的抑制作用．但在一定的浓度范围内，三元固体配合物的抑制效果明显优于稀土硝酸盐和2种配体：稀土配合物对3种癌细胞株生长的抑制作用基…
Reactive Oxygen Species (ROS) are known as important intracellular signaling molecules. These are also well known for their role in oxidative stress and cellular damage, leading to their involvement in several pathologies. Despite the widespread postulation of ROS mechanisms, little is actually known about the immedia…
The field of nanomedicine has progressed to a stage where a diverse set of materials are available for controlling how a drug is delivered in the body. Although these materials can be engineered to overcome many of the obstacles associated with drug delivery, the complexity of cellular trafficking mechanisms means con…
Lack of access to clean and safe potable water, especially for people living in rural areas of developing economies, is a matter of great concern in different parts of the world. Measures taken to address the challenges arising from this problem include the improvement of existing water purification methods and develo…
There is a growing need for synthetic bone graft materials, which is particularly apparent for procedures requiring impaction bone grafting (IBG), such as revision hip arthroplasty. Currently allograft bone is used that has limited supply and associated risks of transmission of infectious agents. Porous bioresorbable…
Las fibras celulosicas se caracterizan por presentar entre otras propiedades buen comportamiento al uso generando confort. Sin embargo, durante el uso y el mantenimiento, tambien se puede apreciar capacidad de encogimiento, arrugado y poca recuperacion a la arruga. Estas propiedades no son deseables y se consiguen pal…
