Characterization of squeeze-cast AIB12/AI and AIB2/AI composites
(2009)
Aluminum alloys containing 2 and 4 wt.% copper reinforced with aluminum borides were successfully fabricated by squeeze casting employing squeezing pressures up to 62 MPa. The distribution of reinforcements in the composites ...
Water transport in the diffusion media of a proton exchange membrane fuel cell (PEMCF)
(2009)
The fuel cell is an electrochemical energy conversion device that produces electricity based on an electrochemical reaction. From the diverse types of fuel cell the proton exchange membrane fuel cell (PEMFC) has better ...
Numerical analysis of Berdut linear electric motor for train propulsion
(2009)
This thesis investigates the performance of the Berdut linear motor for use in the propulsion of trains. This motor is part of a novel technology that uses an array of permanent magnets and iron-based materials in the ...
An experimental study of aluminum boride particles distribution in centrifugally cast AI/AIBx composites
(2009)
In this research, centrifugal casting has been used to investigate the influence of casting parameters and chemical composition on the manufacturing of functionally graded Al-2 wt. %B-6 wt. %Mg and Al-2 wt. %B-6 wt. %Cu ...
Development and characterization of oxide scaffolds on gamma-TiAI surfaces to enhance osseointegration
(2009)
The wear properties of oxidized and non-oxidized gamma-TiAl (a potential biomaterial) as well as Ti-6Al-4V and CP-Ti disks were studied and characterized by means of standard wear tests using a Bone pin arrangement. The ...
Synthesis and characterization of polyimide cobalt ferrite nanocomposites for potential applications in mems
(2009)
In the present work, cobalt ferrite nanocrystals were synthesized under size-controlled conditions in aqueous phase and incorporated into a polyimide matrix at various volumetric loads. Synthesized 20nm-cobalt ferrite ...
Optimization and characterization of a magnetocaloric pump using ferrofluids
(2009-05)
This work presents a detailed analysis of a magnetocaloric pump for electronic cooling applications that runs with no moving mechanical parts and that uses ferrofluid (magnetic fluid) as the working fluid. Mn0.5Zn0.5 Fe2O4 ...
Study of bioheat transfer processes for hyperthermia cancer treatment
(2009)
Hyperthermia is a type of cancer treatment in which cancer cells are exposed to high temperatures (in the range 42-45°C). Research has shown that high temperatures can damage and kill cells by maintaining them in that range ...
Numerical simulation and development of a ferrofluid pumping device driven by electromagnets
(2009-12)
This thesis present a development of an Electromagnet Pumping Device (EPD) using a ferrofluid. A moving magnetic field is used as a driving force. A loop is set up with a series of solenoids which operate sequentially to ...
