According to Paul et al.'s model [1], behavior of CMP slurry abrasives during polishing was modeled as an adsorption/desorption reaction on sites of polishing pad. The model showed a saturation relationship between removal rate and abrasive concentration. In this study, we extended this concept to include repulsive fo…
This thesis discusses optical investigations of two-dimensional metal-chalcogenide semiconductor materials and their heterostructures. Topics include a study of continuous wave (cw) and time-resolved photoluminescence (PL) of GaTe and GaSe thin films. Based on experimental evidence, we propose a model explaining the s…
To remove bromate and chromate from water, common methods include ion exchange, coagulation-flocculation processes, reductionprecipitation, etc., but these strategies can present some important disadvantages like incomplete removal, high cost, continuous use of reagents, and high energy costs. One of the most promisin…
Lithium-ion battery particle-scale (non-porous electrode) simulations applied to resolved electrode geometries predict localized phenomena and can lead to better informed decisions on electrode design and manufacturing. This work develops and implements a fully-coupled finite volume methodology for the simulation of t…
In this paper we will report a novel CMP slurry chemistry which can provide tunable removal selectivity between various silicon-containing materials, such as SiGe, bare silicon, poly silicon or amorphous silicon against SiO2 and/or SiN. The slurry chemistry is a non-hydrogen peroxide based system containing a novel ca…
The purpose of this study is to obtain the Young’s Modulus (elastic property) of Cu6Sn5 phase by using ultrasonic technique and composite theory. Alloy with the following composition (weight percent = wt%): 15.00 % Cu and 85 % Sn was fabricated by casting method. Phases identification were determined by using X-ray Di…
Lamination is an important step in the production of three-dimensional structures using green ceramic tapes. A lot of research was devoted to the refinement of the lamination process; a certain number of lamination methods are known from the literature. The present work deals with the evaluation of the method in which…
Since composites were first used in boat building in the late 1940's, there has been considerable speculation about how these versatile materials could be used for ship building. Dag Pike examines recent developments.
A temperature-induced transition to the macroscopic behavior of the hopping conductivity is observed in Ge/Si quantum-dot heterostructures upon the investigation of light-induced mesoscopic fluctuations of the electric current in these heterostructures. It is shown that the temperature dependence of the relative ampli…
El present projecte te per objectiu principal l’analisi de dos transitoris de categoria IV en reactors d’aigua a pressio utilitzant codis de calcul de sistema i mitjancant calculs de millor estimacio. Ambdos escenaris han estat proposats per ANAV (Associacio Nuclear Asco Vandellos) i per a la seva realitzacio s’ha emp…
In the pharmaceutical field, amphiphilic block copolymers are of great interest for the nanovectorization of active principles in Drug Delivery. Indeed, new drugs are synthesized each day but in too many cases, their high hydrophobicity makes them useless because of the absence of an appropriated administration method…
The paper deals with numerical analyses of a radial flux motor with double-sided rotor. The motor was designed with Nd-Fe-B sintered magnets and soft magnetic stator made of iron powder. The motor was designed for assessment of possibility of construction high torque motors with the powder stator for e.g. electric veh…
Thermoelectric devices offer a reliable all solid state solution to active temperature control and are more and more considered as a promising way for thermal management of Integrated Circuits. However, low material performances still represent a hurdle to the spreading of such devices for high power electronics cooli…
Carbon silicon carbide composite is very important material due to its excellent thermal and mechanical properties, self lubricating and low wear capability. This composite can be used in lubricating oil and grease. The composite is prepared by using new polymeric surfactants. The technique of preparation was suggeste…
The current bottleneck preventing the wider application of time-resolved structural techniques is the ability to quickly and accurately trigger protein function across an ensemble of molecules either in solution or in crystallo. The fastest and most accurate approach to achieve protein function synchronisation is by u…
Arthrobacter nicotinovorans is a gram positive soil actinobacteria which is able to grow on nicotine\ncontaminated soils due to the presence of a large plasmid - pAO1. It has been shown that pAO1 encodes not only the\npathway for nicotine mineralization, but also newly described oxidative xylose-catabolic pathway. Par…
The Fresnel lens arrays, which can be used as the alternative of microlens arrays for integral imaging, were designed and fabricated. Their imaging properties for different colors were investigated, and a design based on the Fresnel lens arrays with chromatic dispersion is proposed.
There is a demand and a need for cheaper and alternative surface coverings in environments with high temperature fluctuations. Our design for an alternative surface covering involves a basic twopart component epoxy with the addition of a solvent. The purpose of the solvent is to disrupt the reaction that forms the ord…
Since Richard Feynman and his famous talk “There’s plenty of room at the bottom” in an American Physical Society meeting at Caltech in 1959, Nanotechnology has led to the development of novel materials and devices with a wide-range of applications, especially in imaging, diagnostics, and therapy, which contributed to…
