Study of Fluid and Mass Adsorption Model in the QCM-D Sensor for Characterization of Biomolecular Interaction
Increasing attention has been paid to application of the quartz crystal microbalance with dissipation (QCM-D) sensor for monitoring biomolecular interactions. This paper focuses on a practical application of protein-protein binding affinity measurement at low concentrations and minimal ... Read More
The Effect of a Correlated Surface Roughness and Convection on Heat Conduction
Heat conduction through a slab, 0 ≤ x ≤ W is one dimensional. However, if one of the edges, say x=0, is rough the conduction will be two dimensional. The two dimensionality varies with the correlation length with a maximum at a length approximately 10% of the slab width. ... Read More
Viscous damping of a periodic perforated MEMS microstructure when the Reynolds’ equation cannot be applied: Numerical simulations
This paper develops a computational model for determining the total damping coefficient for a unit cell of a MEMS microscale device containing a repetitive pattern of holes. The basic cell of the microstructure is approximated by an axi-symmetric domain and the velocity and pressure ... Read More
Finite Element Analysis of Thermal Fatigue in Thermal Barrier Coatings
A Finite element model of plasma sprayed TBC’s was developed to estimate the stress induced by thermal cycling experiments. A heat transfer analysis was performed to evaluate the temperature distribution on the specimen during the cooling under an impinging air jet; temperature ... Read More
Importance of Assembly Discontinuity Factors In Simulating Reactor Cores Containing Highly Heterogeneous Fuel Assemblies
To assess the importance of assembly discontinuity factors (ADF), a highly heterogeneous reactor core was simulated using a COMSOL model in which ADF are not used. The resulting errors in assembly powers were found to be unacceptably high. This indicates that for highly heterogeneous ... Read More

Expanding Your Materials Horizons
Materials and their related properties are intrinsically fundamental to the creation, development and solution of viable exploratory models when using numerical analysis software. In many cases, simply determining the location, availability and relative accuracy of the necessary material ... Read More
Modelling of the Hydrogen Diffusion in Martensitic Steel in Contact with H2SO4 Media
Hydrogen Embrittlement (HE) is one of the mechanisms responsible for premature failure of structures. In the context of environmental sustainability, it is compelling to improve or conceive new processes and/or new materials capable of reducing fracture induced by HE. We analyzed the ... Read More
