Fabrication and characterization of porous aluminum and zinc via selective dissolution of AI-Zn alloys
(2013)
Chemical dealloying can be used to fabricate porous metals by removing one or more of the species out of an alloy. Generally, a corrosive electrolyte is used to selectively dissolve a noble element. Alloy concentration, ...
Turbulent flow over a pin fin array: parametric study
(2010-05)
Modern jet engines reach very high combustion temperatures to achieve higher thermal efficiencies which can damage the turbine blades. Damage can occur in the turbine blade due to the temperature difference between the ...
Template assisted manufacturing of low-temperature copper-based nano solder
(2012)
As a response to new legislation and calls to lead-free technologies, a method is proposed to manufacture nano-copper by means of electroless copper plating on nanofibers templates. Polyacrylonitrile (PAN) nanofibers were ...
Mixed-mode fracture & fatigue analysis of rotating blades using the extended finite element method
(2010)
This work focuses in the analysis of mixed-mode crack propagation and fatigue of two dimensional rotating blades using the Extended Finite Element Method (XFEM). A horizontal plate model simulates a UH-60 helicopter rotor ...
Stability of silver colloid by process control of the synthesis using design of experiments
(2013)
Extensive resources have been utilized to develop SiC (silicon carbide) semiconductor devices, there has been relatively little effort into the development of adequate, environmentally benign electronic packaging materials ...
Virtual reality enabled design reviews using head mounted displays
(2018-05)
This research investigates the use of virtual reality technology to improve the interaction between
design engineers and their virtual prototypes during the product development process. For
this, two experiments were ...
Development of a combined interface and extended finite element method to predict delamination in composite structures
(2015-12)
For this work, an user-defined element (UEL) in ABAQUS was developed in conjunction with
a triangular traction separation law, as the Cohesive Zone Model, that combines the Extended
Finite Element and Cohesive Element ...
Organic/inorganic films for biosensor application
(2011)
Biosensors are becoming increasingly important as practical tools in pathogen detection and
molecular diagnostics. Electrochemical biosensors are of particular interest due to several
advantages including low-cost, easy ...
Wind turbine modeling for computational fluid dynamics
(2012-05)
With the shortage of fossil fuel and the increasing environmental awareness,
wind energy is becoming more and more important. As the market for wind
energy grows, wind turbines and wind farms are becoming larger. ...
Fabrication and characterization of chitin-carbon nanotubes composites
(2015)
Most polymers by themselves have limitations due to their poor mechanical, thermal and
electrical properties compared with metallic and ceramic materials. Therefore, to expand
their range of applications these properties ...
