In this thesis, we explore two important aspects of study of differential equations: analytical and computational aspects. We first consider a partial differential equation model for a static liquid surface (capillary surface). We prove through mathematical analyses that the solution of this mathematical model (the La…
Abstract : The goals of this project were to synthesize, characterize and model bulk nanostructured composite materials for thermoelectric energy conversion applications. The objective was to produce materials which demonstrate an increase in intrinsic thermoelectric efficiency of a factor of two or more over existing…
Warm Mix Asphalt (WMA) used as an alternative to conventional Hot Mix Asphalt (HMA) has gained national prominence. WMA uses technological advances that reduce the temperature needed to produce and compact asphalt for the construction of pavements, which results in lower costs, improved worker health, increased safety…
This paper addresses the problem of controlling hydrocarbon emissions from cold-start of engines by investigating the adsorbents which could adsorb the hydrocarbons at cold temperatures and hold them to 250-300 ?. The materials, that has been studied, are based on the modification of ZSM-5 (SiO{sub 2}/Al{sub 2}O{sub 3…
Space Grade Spectralon® (SGS) has become a standard tool for on-board satellite instrument calibration and verification schemes. This paper provides an overview of the development process, a comprehensive history of the development of SGS, its space qualification, and characterization and degradation studies performed…
Una red interpenetrada (IPN) consiste en la combinacion de dos redes polimericas diferentes, sin que haya enlaces covalentes entre ellas; de esta forma se consigue una mezcla fisica que contiene polimeros entrecruzados. Este tipo de polimeros se prepara por el entrecruzamiento simultaneo o secuencial de dos sistemas d…
Alcator C-Mod is planning an upgrade to its outer divertor. The upgrade is intended to correct the existing outer divertor alignment with the plasma, and to operate at elevated temperatures. Higher temperature operation will allow study of edge physics behavior at reactor relevant temperatures. The outer divertor and…
The supramolecular chemistry of polyhydroxylated compounds (called carbohydrates) is well established. It essentially comprises strong O–H···O and C–H···O H-bonds. The crystallization of these compounds has been carried out innumerable times and has resulted in the formation of a single polymorph only. But recent effo…
We describe a procedure for designing metal-metal boundaries for the strong attenuation of surface plasmon-polaritons without the introduction of reflections or scattering effects. Solutions associated with different sets of matching materials are found. To illustrate the results and the consequences of adopting diffe…
Current trends in the formulation for new food shows that healthy or “functional†products are graduallyincreasing their participation in the preference of the consumers (Catalá Ramón). Nowadays, the participation of meatproducts in this behavior of the marketing is not growing at the same rate, because their ingr…
Recent experiments show that certain self-assembled polymer nanocomposites exhibit colossal dielectric constants (∼4000 at 20 Hz), as compared to eight for the polymer matrix, even for small filler volume fractions (∼7%). However, reasons for this are not well understood. In this work, two possible explanations are sy…
European policy drivers exist to improve the design and deployment of power cable systems in transmission networks, particularly the whole life cycle of future low carbon networks. As part of a new power cable development project called SUSCABLE, a new high temperature and recyclable thermoplastic blend HV power cable…
The TLP bonding is distinguished from brazing processes by the isothermal solidification of this liquid. This is accomplished since the interlayer is rich in a melting point depressant (MPD). Upon heating through the eutectic temperature, the interlayer will either melt or react with the base metal to form a liquid. D…
The designers of electro energetic system are thinking, to conserve the routes of 220kV transmission lines, and the transition to 400kV lines. The easiest way seems to be the placement of new overhead power lines. The other option is the use of covered conductors. Covered conductors are conductors with insulation made…
Este trabalho consiste no estudo das caracteristicas e propriedades de tijolos oriundos das composicoes binarias de solo-cimento, com a incorporacao da cinza do bagaco de cana-de-acucar, formando assim as composicoes ternarias que poderao ser utilizadas pela industria, com a finalidade de se obter um produto de elevad…

It is known that the physical–chemical properties of the metallic alloy surfaces differ markedly from that of the bulk and, mainly, it is caused by segregation one of the alloy components on the surface [1]. It is related to the fact that the physical–chemical state of the surface substantially influences such surface…
Titanium alloys like the modern alloy Ti 6Al 2Sn 4Zr 6Mo (Ti-6246) combine excellent specific mechanical properties and corrosion resistance. On the other hand,due to their material characteristics, machining of these alloys is difficult to perform. The aim of the current study is the analyses of wear mechanisms of co…
We report synthesis and superconductivity at 3.7K in PrO0.5F0.5BiS2. The newly discovered material belongs to the layered sulfide based REO0.5F0.5BiS2 compounds having ZrCuSiAs type structure. The bulk polycrystalline compound is synthesized by vacuum encapsulation technique at 7800C in single step. Detailed structura…
