The Effect of Certain Morphological Features on the Permeability of Clustered Fibrous Media
(2009)A good understanding of the microscopic details of flow through fiber preforms remains a critical step in the design and optimization of composite liquid molding processes such as Resin Transfer Molding (RTM) and its ... -
Effect of Contact Line Dynamics on the Thermocapillary Motion of a Droplet on an Inclined Plate
(2013)We study the two-dimensional dynamics of a droplet on an inclined, nonisothermal solid substrate. We use lubrication theory to obtain a single evolution equation for the interface, which accounts for gravity, capillarity, ... -
An EPR study of Cu adsorption by clinoptilolite from Cl-, NO3 and SO42- solutions
(2008)The concentration and the type of Cu2+ species adsorbed on a natural zeolite (Clinoptilolite) was measured and studied by using Electron Paramagnetic Resonance Spectroscopy (EPR). The EPR results together with macroscopic ... -
Modeling of surface finish in electro-discharge machining based upon statistical multi-parameter analysis
(2004)A multi-parameter analysis of surface finish imparted to Ck60 steel plates by electro-discharge machining (EDM) is presented. The interrelationship between surface texture parameters and process parameters is emphasized. ... -
Modelling of microsegregation and homogenization of 6061 extrudable Al-alloy
(2007)A simulation of the evolution of the as-cast microstructure during the homogenization heat treatment of A6061 aluminum alloy is presented. The microstructure is dendritic with phase and solute segregation. The alloy ... -
The Modified Rockwell Test: A New Probe for Mechanical Properties of Metals
(2009)In the present work a novel methodology is proposed, based on the combination of the Rockwell and the Vickers tests, to provide estimates of the mechanical properties of metal substrates. The analysis is based on some novel ... -
Non-contact Current Transfer Induces the Formation and Improves the X-ray Diffraction Quality of Protein Crystals
(2014)The effect of non-contact current transfer on the crystallization of three model proteins (hen egg white lysozyme, bovine pancreatic ribonuclease A, and human recombinant insulin) was investigated using a prototype ... -
Numerical investigation of the buckling behavior of thin ferrocement stiffened plates
(2015)One of the most common applications of ferrocement is the manufacturing of thin stiffened plates which are prone to buckling. This study focuses on the investigation of the behavior of a ferrocement plate, stiffened in ... -
Precipitation of calcium phosphate from simulated milk ultrafiltrate solutions
(2007)The present work deals with the influence of pH and temperature on the spontaneous precipitation of calcium phosphate from simulated milk ultrafiltrate (SMUF) solutions. The pH range investigated is 5.7-7.0, and the ... -
Simulation of the transformation of iron intermetallics during homogenization of 6xxx series extrudable aluminum alloys
(2012)A computational simulation of the beta-AlFeSi to alpha-AlFeSi transformation has been performed in this work by integrating the process steps of solidification and homogenization. The composition profiles of alloying ... -
Superhydrophobic composite films produced on various substrates
(2008)Hydrophilic silica NOD nanoparticles were dispersed in solutions of poly(methyl methacrylate) (PMMA) and in solutions of a commercial poly(alkyl siloxane) (Rhodorsil 224), and the suspensions were sprayed on glass surfaces. ... -
Synthesis and characterization of poly(3-sulfopropylmethacrylate) brushes for potential antibacterial applications
(2007)This article describes the aqueous atom transfer radical polymerization synthesis of poly(3-sulfopropylmethacrylate) brushes onto gold and Si/SiO2 surfaces in a controlled manner. The effect of Cu(I)/Cu(II) ratio was ... -
Thermocapillary-Driven Motion of a Sessile Drop: Effect of Non-Monotonic Dependence of Surface Tension on Temperature
(2014)We study the thermocapillary-driven spreading of a droplet on a nonuniformly heated substrate for fluids associated with a non-monotonic dependence of the surface tension on temperature. We use lubrication theory to derive ...
