The adhesive contact of a flat punch on a hyperelastic substrate subject to a pull-out force or a bending moment
(2011)In the last decade; instrumented macro- and nano-indentation tests have become useful tools for probing mechanical properties of materials. In this context, little in-depth work has been done for soft bio-materials like ... -
Adjustable Hyperthermia Response of Self-Assembled Ferromagnetic Fe-MgO Core-Shell Nanoparticles by Tuning Dipole-Dipole Interactions
(2012)The Fe-MgO core-shell morphology is proposed within the single-domain nanoparticle regime as an enhanced magnetically driven hyperthermia carrier. The combinatory use of metallic iron as a core material together with the ... -
Advanced Modeling of Composite Slabs with Thin-Walled Steel Sheeting Submitted to Fire
(2013)The paper studies the behavior of composite slabs with corrugated steel sheeting at elevated temperatures. Two structural systems are considered: a simply supported composite slab and a continuous composite slab that ... -
Analysis of heat affected zone in welded aluminum alloys using inverse and direct modeling
(2008)The concept of constructing parameter spaces for process control and the prediction of properties within the heat affected zone (HAZ) of welds using inverse modeling is examined. These parameter spaces can be, in principle, ... -
Analysis of Knoop indentation of cohesive frictional materials
(2013)During the last decades, pyramid micro and nano-indentation tests such as Vickers, Berkovich and Knoop have been used on cohesive-frictional (pressure sensitive) materials, such as hard metals, glasses and ceramics, and ... -
Automated material handling and just-in-time
(1998)Material handling is a very important part of any industry, and with new technological advances this field has become easier to deal with. This article looks at different aspects of what is happening with automation and ... -
BaCeO3: Materials development, properties and application
(2014)The characteristic of a number of oxide materials, which include BaCeO3-systems, is their ability to show the proton conductivity along with oxygen-ion conductivity. Such atypical behavior for other oxides attracts great ... -
BIOFUNCTIONALIZATION OF PET/SiO2 SURFACES FOR SINGLE MOLECULE EXPERIMENTS AND MEDICAL APPLICATIONS
(2011)PET/SiO2 layers were chemically modified to maintain immobilization of functional single molecules. GFP molecules provide an ideal system due to their stability and intrinsic fluorescence. GFP in vivo biotinylated within ... -

(2012)In this article, case-study inverse thermal analyses of Al2198 laser welds are presented. These analyses employ a numerical methodology, that is, in terms of analytic and numerical basis functions for inverse thermal ... -
Characterization of the interaction between peptides derived from the gp 120/V3 domain of HIV-1 and the amino terminal of the chemokine receptor CCR5 by NMR spectroscopy and light scattering
(2006)We applied static and dynamic light scattering (DLS) to probe the structural and physicochemical determinants of the interaction between the gp120 V3 domain of the human immunodeficiency virus HIV-1 and the amino terminal ... -
Constitutive modeling of solid propellant materials with evolving microstructural damage
(2008)Solid propellants are composite materials with complex microstructure. In a generic form, the material consists of polymeric binder, crystal oxidizer (e.g., ammonium perchlorate), and fuel particles (e.g., aluminum). Severe ... -
Control of representative turned surface textures
(2004)A method for characterizing machined surface textures corresponding to varying cutting conditions, which lead to differing profile shapes, is presented here. Through a proper multi-parameter analysis carried out on turned ... -
Corrosion-induced hydrogen embrittlement in aluminum alloy 2024
(2006)The present paper focuses on the observed corrosion-induced embrittlement of alloy 2024 and tries to answer the key question on whether the observed embrittlement is attributed to hydrogen uptake and trapping in the material. ... -
Derivation of strain gradient length via homogenization of heterogeneous elastic materials
(2013)We present explicit upper bound estimates of the microstructural length used in simple gradient elasticity. Our model is a two dimensional composite made of circular hard inclusions randomly dispersed in a soft matrix. ... -
