Electric fields are present in biological systems at multiple spatial and temporal scales. Electroosmotic flow results from the action of electric field on the electrical double layer, formed at the fluid/solid or fluid/membrane interface and characterized by its zeta-potential. For the physiological value of zeta-potential (50 mV) and a single charged protein of average size, electroosmotic ...

The predictive engineering of materials is matured from predicting properties from known morphology or constituents to engineering novel morphology for superior properties. The focus of this paper is about implementation of computational material mechanics modeling method in COMSOL Multiphysics software for engineering the constituents for superior properties. A brief review of property ...
This paper covers the following: * All-Optical Light Modulation of surface plasmon polaritons (SPPs) is achieved using asymmetric single nanoslits. A high on/off switching ratio of >20 dB and phase variation of >? were observed with the device lateral dimension of only about 2 ?m. * Efficient unidirectional excitation of SPP as well as beam splitting are achieved using the dielectric–film ...

Experimental data for oscillations occurring at the three phase contact line of an evaporating HFE 7000 meniscus on a silica substrate is presented. The frequency of the oscillations were found to depend on the local value of the evaporative heat ?ux. The thickness, slope, and curvature of the vapor-liquid interface were determined using an interferometry technique, which allowed us to calculate ...

The objective of the work is to propose a reliability enhancement model for antigen detection system (ADS) using bio MEMS based cantilever array sensors using heterogeneous modular redundancy technique. The reliability of the ADS is expressed in terms of the constituent sub systems which are heterogeneous not only in their respective structures and behaviors but also in their forms. The possible ...

Previous studies proposed using bipolar radiofrequency ablation across two catheters placed on opposing surfaces of the ventricular wall to create transmural lesions. 2D and 3D models were built and solved with COMSOL Multiphysics software. With these models, it was possible to study the temperature distribution and lesion geometry (Figure), to compare the potential of two ways of applying ...

We describe simulations performed in COMSOL Multiphysics® of the precipitation of helium (He) on solid-state interfaces. The non-uniform precipitation of He at certain interfaces is a result of a heterogeneous energy distribution in the interface plane: He wets high interface energy (“heliophilic”) regions but does not wet low interface energy (“heliophobic”) ones. Using a phase-field model, ...
